The Growing Role of Cybersecurity in Protecting Nations

 




It is becoming increasingly complex and volatile for nations to cope with the threat landscape facing them in an age when the boundaries between the digital and physical worlds are rapidly dissolving. Cyberattacks have evolved from isolated incidents of data theft to powerful instruments capable of undermining economies, destabilising governments and endangering the lives of civilians. 

It is no secret that the accelerating development of technologies, particularly generative artificial intelligence, has added an additional dimension to the problem at hand. A technology that was once hailed as a revolution in innovation and defence, GenAI has now turned into a double-edged sword.

It has armed malicious actors with the capability of automating large-scale attacks, crafting convincing phishing scams, generating convincing deepfakes, and developing adaptive malware that is capable of sneaking past conventional defences, thereby giving them an edge over conventional adversaries. 

Defenders are facing a growing set of mounting pressures as adversaries become increasingly sophisticated. There is an estimated global cybersecurity talent gap of between 2.8 and 4.8 million unfilled positions, putting nearly 70% of organisations at risk. Meanwhile, regulatory requirements, fragile supply chains, and an ever-increasing digital attack surface have compounded vulnerabilities across a broad range of industries. 

Geopolitics has added to the tensions against this backdrop, exacerbated by the ever-increasing threat of cybercrime. There is no longer much difference between espionage, sabotage, and warfare when it comes to state-sponsored cyber operations, which have transformed cyberspace into a crucial battleground for national power. 

It has been evident in recent weeks that digital offensives can now lead to the destruction of real-world infrastructure—undermining public trust, disrupting critical systems, and redefining the very concept of national security—as they have been used to attack Ukraine's infrastructure as well as campaigns aimed at crippling essential services around the globe. 

In India, there is an ambitious goal to develop a $1 trillion digital economy by the year 2025, and cybersecurity has quietly emerged as a key component of that transformation. In order to support the nation's digital expansion—which covers financial, commerce, healthcare, and governance—a fragile yet vital foundation of trust is being built on a foundation of cybersecurity, which has now become the scaffolding for this expansion. 

It has become more important than ever for enterprises to be capable of anticipating, detecting, and neutralising threats, as artificial intelligence, cloud computing, and data-driven systems are increasingly integrated into their operations. This ability is critical not only to their resilience but also to their long-term competitiveness. In addition to the increasing use of digital technologies, the complexity of safeguarding interconnected ecosystems has increased as well. 

During October's Cybersecurity Awareness Month 2025, a renewed focus has been placed on strengthening artificial intelligence-powered defences as well as encouraging collective security measures. As a senior director at Acuity Knowledge Partners, Sameer Goyal stated that India's financial and digital sectors are increasingly operating within an always-on, API-driven environment defined by instant payments, open platforms, and expanding integrations with third-party services—factors that inevitably widen the attack surface for hackers. He argued that security was not an optional provision; it was fundamental. 

Taking note of the rise in sophisticated threats such as account takeovers, API abuse, ransomware, and deepfake fraud, he indicated that security is not optional. According to him, the primary challenge of a company is to protect its customers' trust while still providing frictionless digital experiences. According to Goyal, forward-thinking organisations are focusing on three key strategic pillars to ensure their digital experiences are frictionless: adopting zero-trust architectures, leveraging artificial intelligence for threat detection, and incorporating secure-by-design principles into development processes. 

Despite this caution, he warned that technology alone cannot guarantee security. For true cyber readiness, employees should be well-informed, well-practised and well-rehearsed in incident response playbooks, as well as participate in proactive red-team and purple-team simulations. “Trust is our currency in today’s digital age,” he said. “By combining zero-trust frameworks with artificial intelligence-driven analytics, cybersecurity has become much more than compliance — it is becoming a crucial element of competitiveness.” 

Among the things that make cybersecurity an exceptionally intricate domain of diplomacy are its deep entanglement with nearly every dimension of international relations-economics, military, and human rights, to name a few. As a result of the interconnectedness of our society, data movement across borders has become as crucial to global commerce as capital and goods moving across borders. It is no longer just tariffs and market access that are at the centre of trade disputes. 

It is also about the issues of data localisation, encryption standards, and technology transfer policies that matter the most. While the General Data Protection Regulation (GDPR) sets an international standard for data protection, it has also become a focal point in a number of ongoing debates regarding digital sovereignty and cross-border data governance that have been ongoing for some time. 

 As far as defence and security are concerned, geopolitical stakes are of equal importance to those of air, land, and sea. Since NATO officially recognised cyberspace in 2016—as a distinct operational domain comparable with the other three domains—allies have expanded their collective security frameworks to include cyber defence. To ensure a rapid collective response to cyber incidents, nations share threat intelligence, conduct simulation exercises, and harmonise their policies in coordination with one another. 

The alliance still faces a dilemma which is very sensitive and unresolved to the point where determining the threshold at which a cyberattack would qualify as an act of aggression enough to trigger Article 5, which is the cornerstone of NATO's commitment to mutual defence. Cybersecurity has become inextricable from concerns about human rights and democracy as well, in addition to commerce and defence.

In recent years, authoritarian states have increasingly abused digital tools for spying on dissidents, manipulating public discourse, and undermining democratic institutions abroad. As a consequence of these actions, the global community has been forced to examine issues of accountability and ethical technology use. The diplomatic community struggles with the establishment of international norms for responsible behaviour in cyberspace while it must navigate profound disagreements over internet governance, censorship, and the delicate balancing act between national security and individuals' privacy through the process of developing ethical norms.

There is no doubt that the tensions around cybersecurity have emerged over time from merely being a technical issue to becoming one of the most consequential arenas in modern diplomacy-shaping not only international stability, but also the very principles that underpin global cooperation. Global cybersecurity leaders are facing an age of uncertainty in the face of a raging tide of digital threats to economies and societies around the world. 

Almost six in ten executives, according to the Global Cybersecurity Outlook 2025, feel that cybersecurity risks have intensified over the past year, with almost 60 per cent of them admitting that geopolitical tensions are directly influencing their defence strategies in the near future. According to the survey, one in three CEOs is most concerned about cyber espionage, data theft, and intellectual property loss, and another 45 per cent are concerned about disruption to their business operations. 

Even though cybersecurity has increasingly become a central component of corporate and national strategy, these findings underscore a broader truth: cybersecurity is no longer just for IT departments anymore. Experts point out that the threat landscape has become increasingly complex over the past few years, but generative artificial intelligence offers both a challenge and an opportunity as well. 

Several threat actors have learned to weaponise artificial intelligence so they can craft realistic deepfakes, automate phishing campaigns, and develop adaptive malware, but defenders are also utilising the same technology to enhance their resilience. The advent of AI-enabled security systems has revolutionised the way organisations anticipate and react to threats by analysing anomalies in real time, automating response cycles, and simulating complex attack vectors. 

It is important to note, however, that progress remains uneven, with large corporations and developed economies being able to deploy cutting-edge artificial intelligence defences, but smaller businesses and public institutions continue to suffer from outdated infrastructure and a lack of talented workers, which makes global cybersecurity preparedness a growing concern. However, several nations are taking proactive steps toward closing this gap.

An example is the United Arab Emirates, which embraces cybersecurity not just as a technology imperative but also as a societal responsibility. A National Cybersecurity Strategy for the UAE was unveiled in early 2025. It is based on five pillars — governance, protection, innovation, capacity building, and partnerships. It is structured around five core pillars. It was also a result of these efforts that the UAE Cybersecurity Council, in partnership with the Tawazun Council and Lockheed Martin, established a Cybersecurity Centre of Excellence, which would develop domestic expertise and align national capabilities with global standards.

As a result of its innovative Public-Private-People model, which combines school curricula with nationwide drill and strengthens coordination between government and private sector, the country can further embed cybersecurity awareness across society. As a result of this approach, a more general realisation is taking shape globally: cybersecurity should be enshrined in the fabric of national governance, not as a secondary item but as a fundamental aspect of national governance. If cyber resilience is to be reframed as a core component of national security, sustained investment in infrastructure, talent, and innovation is needed, as well as rigorous oversight at the board and policy levels. 

The plan calls for the establishment of red-team exercises, stress testing, and cross-border intelligence sharing to prevent local incidents from spiralling into systemic crises. The collective action taken by these institutions marks an important shift in global security thinking, a shift that recognises that an economy's vitality and geopolitical stability are inseparable from the resilience of a nation's digital infrastructure. 

In the era of global diplomacy, cybersecurity has grown to be a key component, but it is much more than just an administrative adjustment or a passing policy trend. In this sense, it indicates the acknowledgement that all of the world's security, economic stability, and individual rights are inextricably intertwined within the fabric of the internet and cyberspace that we live in today. 

Considering the sophistication and borderless nature of threats in today's world, the field of cyber diplomacy is becoming more and more important as a defining arena of global engagement as a result. As much as traditional forms of military and economic statecraft play a significant role in shaping global stability, the ability to foster cooperation, set shared norms, and resolve digital conflicts holds as much weight.

In the international community, the central question facing it is no longer whether the concept of cybersecurity deserves to be included in diplomatic dialogue, but rather how effectively global institutions can implement this recognition into tangible results in the future. To maintain peace in an era where the next global conflict could start with just one line of malicious code, it is becoming imperative to establish frameworks for responsible behaviour, enhance transparency, and strengthen crisis communications mechanisms. 

Quite frankly, the stakes are simply too high, as if they were not already high enough. Considering how easily a cyberattack can disrupt power grids, paralyse transportation systems, or compromise electoral integrity, diplomacy in the digital sphere has become crucial to the protection of international order, especially in a world where cyberattacks are a daily occurrence.

The cybersecurity diplomacy sector is now a cornerstone of 21st-century governance – vital to safeguarding the interests of not only national governments, but also the broader ideals of peace, prosperity, and freedom that are at the foundation of globalisation. During these times of technological change and geopolitical uncertainty, the reality of cyber security is undeniable — it is no longer a specialized field but rather a shared global responsibility that requires all nations, corporations, and individuals to embrace a mindset in which digital trust is seen as an investment in long-term prosperity, and cyber resilience is seen as a crucial part of enhancing long-term security. 

The building of this future will not only require advanced technologies but also collaboration between governments, industries, and academia to develop skilled professionals, standardise security frameworks, and create a transparent approach to threat intelligence exchange. For the digital order to remain secure and stable, it will be imperative to raise public awareness, develop ethical technology, and create stronger cross-border partnerships. 

Those countries that are able to embrace cybersecurity in governance, innovation, and education right now will define the next generation of global leaders. There will come a point in the future when the strength of digital economies will not depend merely on their innovation, but on the depth of the protection they provide, for the interconnected world ahead will demand a currency of security that will represent progress in the long run.

Madras High Court says cryptocurrencies are property, not currency — what the ruling means for investors

 



Chennai, India — In a paradigm-shifting  judgment that reshapes how India’s legal system views digital assets, the Madras High Court has ruled that cryptocurrencies qualify as property under Indian law. The verdict, delivered by Justice N. Anand Venkatesh, establishes that while cryptocurrencies cannot be considered legal tender, they are nonetheless assets capable of ownership, transfer, and legal protection.


Investor’s Petition Leads to Legal Precedent

The case began when an investor approached the court after her 3,532.30 XRP tokens, valued at around ₹1.98 lakh, were frozen by the cryptocurrency exchange WazirX following a major cyberattack in July 2024.

The breach targeted Ethereum and ERC-20 tokens, resulting in an estimated loss of $230 million (approximately ₹1,900 crore) and prompted the platform to impose a blanket freeze on user accounts.

The petitioner argued that her XRP holdings were unrelated to the hacked tokens and should not be subject to the same restrictions. She sought relief under Section 9 of the Arbitration and Conciliation Act, 1996, requesting that Zanmai Labs Pvt. Ltd., the Indian operator of WazirX, be restrained from redistributing or reallocating her digital assets during the ongoing restructuring process.

Zanmai Labs contended that its Singapore-based parent company, Zettai Pte Ltd, was undergoing a court-supervised restructuring that required all users to share losses collectively. However, the High Court rejected this defense, observing that the petitioner’s assets were distinct from the ERC-20 tokens involved in the hack.

Justice Venkatesh ruled that the exchange could not impose collective loss-sharing on unrelated digital assets, noting that “the tokens affected by the cyberattack were ERC-20 coins, which are entirely different from the petitioner’s XRP holdings.”


Court’s Stance: Cryptocurrency as Property

In his judgment, Justice Venkatesh explained that although cryptocurrencies are intangible and do not function as physical goods or official currency, they meet the legal definition of property.

He stated that these assets “can be enjoyed, possessed, and even held in trust,” reinforcing their capability of ownership and protection under law.

To support this interpretation, the court referred to Section 2(47A) of the Income Tax Act, which classifies cryptocurrencies as Virtual Digital Assets (VDAs). This legal category recognizes digital tokens as taxable and transferable assets, strengthening the basis for treating them as property under Indian statutes.


Jurisdiction and Legal Authority

Addressing the question of jurisdiction, the High Court noted that Indian courts have the authority to protect assets located within the country, even if international proceedings are underway. Justice Venkatesh cited the Supreme Court’s 2021 ruling in PASL Wind Solutions v. GE Power Conversion India, which affirmed that Indian courts retain the right to intervene in matters involving domestic assets despite foreign arbitration.

Since the petitioner’s crypto transactions were initiated in Chennai and linked to an Indian bank account, the Madras High Court asserted complete jurisdiction to hear the dispute.

Beyond resolving the individual case, Justice Venkatesh emphasized the urgent need for robust regulatory and governance frameworks for India’s cryptocurrency ecosystem.

The judgment recommended several safeguards to protect users and maintain market integrity, including:

• Independent audits of cryptocurrency exchanges,

• Segregation of customer funds from company finances, and

• Stronger KYC (Know Your Customer) and AML (Anti-Money Laundering) compliance mechanisms.

The court underlined that as India transitions toward a Web3-driven economy, accountability, transparency, and investor protection must remain central to digital asset governance.


Impact on India’s Crypto Industry

Legal and financial experts view the judgment as a turning point in India’s treatment of digital assets.

By recognizing cryptocurrencies as property, the ruling gives investors a clearer legal foundation for ownership rights and judicial remedies in case of disputes. It also urges exchanges to improve corporate governance and adopt transparent practices when managing customer funds.

“This verdict brings long-needed clarity,” said a corporate lawyer specializing in digital finance. “It does not make crypto legal tender, but it ensures that investors’ holdings are legally recognized as assets, something the Indian market has lacked.”

The decision is expected to influence future policy discussions surrounding the Digital India Act and the government’s Virtual Digital Asset Taxation framework, both of which are likely to define how crypto businesses and investors operate in the country.


A Legally Secure Digital Future

By aligning India’s legal reasoning with international trends, the Madras High Court has placed the judiciary at the forefront of global crypto jurisprudence. Similar to rulings in the UK, Singapore, and the United States, this decision formally acknowledges that cryptocurrencies hold measurable economic value and are capable of legal protection.

While the ruling does not alter the Reserve Bank of India’s stance that cryptocurrencies are not legal currency, it does mark a decisive step toward legal maturity in digital asset regulation.

It signals a future where blockchain-based assets will coexist within a structured legal framework, allowing innovation and investor protection to advance together.



AI Poisoning: How Malicious Data Corrupts Large Language Models Like ChatGPT and Claude

 

Poisoning is a term often associated with the human body or the environment, but it is now a growing problem in the world of artificial intelligence. Large language models such as ChatGPT and Claude are particularly vulnerable to this emerging threat known as AI poisoning. A recent joint study conducted by the UK AI Security Institute, the Alan Turing Institute, and Anthropic revealed that inserting as few as 250 malicious files into a model’s training data can secretly corrupt its behavior. 

AI poisoning occurs when attackers intentionally feed false or misleading information into a model’s training process to alter its responses, bias its outputs, or insert hidden triggers. The goal is to compromise the model’s integrity without detection, leading it to generate incorrect or harmful results. This manipulation can take the form of data poisoning, which happens during the model’s training phase, or model poisoning, which occurs when the model itself is modified after training. Both forms overlap since poisoned data eventually influences the model’s overall behavior. 

A common example of a targeted poisoning attack is the backdoor method. In this scenario, attackers plant specific trigger words or phrases in the data—something that appears normal but activates malicious behavior when used later. For instance, a model could be programmed to respond insultingly to a question if it includes a hidden code word like “alimir123.” Such triggers remain invisible to regular users but can be exploited by those who planted them. 

Indirect attacks, on the other hand, aim to distort the model’s general understanding of topics by flooding its training sources with biased or false content. If attackers publish large amounts of misinformation online, such as false claims about medical treatments, the model may learn and reproduce those inaccuracies as fact. Research shows that even a tiny amount of poisoned data can cause major harm. 

In one experiment, replacing only 0.001% of the tokens in a medical dataset caused models to spread dangerous misinformation while still performing well in standard tests. Another demonstration, called PoisonGPT, showed how a compromised model could distribute false information convincingly while appearing trustworthy. These findings highlight how subtle manipulations can undermine AI reliability without immediate detection. Beyond misinformation, poisoning also poses cybersecurity threats. 

Compromised models could expose personal information, execute unauthorized actions, or be exploited for malicious purposes. Previous incidents, such as the temporary shutdown of ChatGPT in 2023 after a data exposure bug, demonstrate how fragile even the most secure systems can be when dealing with sensitive information. Interestingly, some digital artists have used data poisoning defensively to protect their work from being scraped by AI systems. 

By adding misleading signals to their content, they ensure that any model trained on it produces distorted outputs. This tactic highlights both the creative and destructive potential of data poisoning. The findings from the UK AI Security Institute, Alan Turing Institute, and Anthropic underline the vulnerability of even the most advanced AI models. 

As these systems continue to expand into everyday life, experts warn that maintaining the integrity of training data and ensuring transparency throughout the AI development process will be essential to protect users and prevent manipulation through AI poisoning.

Arctic Wolf Report Reveals IT Leaders’ Overconfidence Despite Rising Phishing and AI Data Risks

 

A new report from Arctic Wolf highlights troubling contradictions in how IT leaders perceive and respond to cybersecurity threats. Despite growing exposure to phishing and malware attacks, many remain overly confident in their organization’s ability to withstand them — even when their own actions tell a different story.  

According to the report, nearly 70% of IT leaders have been targeted in cyberattacks, with 39% encountering phishing, 35% experiencing malware, and 31% facing social engineering attempts. Even so, more than three-quarters expressed confidence that their organizations would not fall victim to a phishing attack. This overconfidence is concerning, particularly as many of these leaders admitted to clicking on phishing links themselves. 

Arctic Wolf, known for its endpoint security and managed detection and response (MDR) solutions, also analyzed global breach trends across regions. The findings revealed that Australia and New Zealand recorded the sharpest surge in data breaches, rising from 56% in 2024 to 78% in 2025. Meanwhile, the United States reported stable breach rates, Nordic countries saw a slight decline, and Canada experienced a marginal increase. 

The study, based on responses from 1,700 IT professionals including leaders and employees, also explored how organizations are handling AI adoption and data governance. Alarmingly, 60% of IT leaders admitted to sharing confidential company data with generative AI tools like ChatGPT — an even higher rate than the 41% of lower-level employees who reported doing the same.  

While 57% of lower-level staff said their companies had established policies on generative AI use, 43% either doubted or were unaware of any such rules. Researchers noted that this lack of awareness and inconsistent communication reflects a major policy gap. Arctic Wolf emphasized that organizations must not only implement clear AI usage policies but also train employees on the data and network security risks these technologies introduce. 

The report further noted that nearly 60% of organizations fear AI tools could leak sensitive or proprietary data, and about half expressed concerns over potential misuse. Arctic Wolf’s findings underscore a growing disconnect between security perception and reality. 

As cyber threats evolve — particularly through phishing and AI misuse — complacency among IT leaders could prove dangerous. The report concludes that sustained awareness training, consistent policy enforcement, and stronger data protection strategies are critical to closing this widening security gap.

The Fragile Internet: How Small Failures Trigger Global Outages






The modern internet, though vast and advanced, remains surprisingly delicate. A minor technical fault or human error can disrupt millions of users worldwide, revealing how dependent our lives have become on digital systems.

On October 20, 2025, a technical error in a database service operated by Amazon Web Services (AWS) caused widespread outages across several online platforms. AWS, one of the largest cloud computing providers globally, hosts the infrastructure behind thousands of popular websites and apps. As a result, users found services such as Roblox, Fortnite, Pokémon Go, Snapchat, Slack, and multiple banking platforms temporarily inaccessible. The incident showed how a single malfunction in a key cloud system can paralyze numerous organizations at once.

Such disruptions are not new. In July 2024, a faulty software update from cybersecurity company CrowdStrike crashed around 8.5 million Windows computers globally, producing the infamous “blue screen of death.” Airlines had to cancel tens of thousands of flights, hospitals postponed surgeries, and emergency services across the United States faced interruptions. Businesses reverted to manual operations, with some even switching to cash transactions. The event became a global lesson in how a single rushed software update can cripple essential infrastructure.

History provides many similar warnings. In 1997, a technical glitch at Network Solutions Inc., a major domain registrar, temporarily disabled every website ending in “.com” and “.net.” Though the number of websites was smaller then, the event marked the first large-scale internet failure, showing how dependent the digital world had already become on centralized systems.

Some outages, however, have stemmed from physical damage. In 2011, an elderly woman in Georgia accidentally cut through a fiber-optic cable while scavenging for copper, disconnecting the entire nation of Armenia from the internet. The incident exposed how a single damaged cable could isolate millions of users. Similarly, in 2017, a construction vehicle in South Africa severed a key line, knocking Zimbabwe offline for hours. Even undersea cables face threats, with sharks and other marine life occasionally biting through them, forcing companies like Google to reinforce cables with protective materials.

In 2022, Canada witnessed one of its largest connectivity failures when telecom provider Rogers Communications experienced a system breakdown that halted internet and phone services for roughly a quarter of the country. Emergency calls, hospital appointments, and digital payments were affected nationwide, highlighting the deep societal consequences of a single network failure.

Experts warn that such events will keep occurring. As networks grow more interconnected, even a small mistake or single-point failure can spread rapidly. Cybersecurity analysts emphasize the need for stronger redundancy, slower software rollouts, and diversified cloud dependencies to prevent global disruptions.

The internet connects nearly every part of modern life, yet these incidents remind us that it remains vulnerable. Whether caused by human error, faulty code, or damaged cables, the web’s fragility shows why constant vigilance, better infrastructure planning, and verified information are essential to keeping the world online.



Windows 11’s Auto-Enabled BitLocker Locks User Out of Terabytes of Data — Here’s What Happened

 

Microsoft first introduced BitLocker drive encryption with Windows Vista back in 2007, though it was initially limited to the Enterprise and Ultimate editions. Over the years, it evolved into a core security feature of Windows. With Windows 11, Microsoft went a step further — BitLocker now activates automatically when users sign in with a Microsoft account during the setup process (OOBE). While this auto-encryption aims to secure user data, it has also caused some serious unintended consequences.

That’s exactly what happened to one unfortunate Reddit user, u/Toast_Soup (referred to as “Soup”), who ended up losing access to their data after a Windows reinstall.

Soup noticed their PC was lagging and decided to perform a clean installation of Windows. Their system had six drives — including the boot drive and two large backup drives (D: and E:), each with around 3TB of data. But once the reinstall was complete, those two drives appeared to have vanished. They were locked by BitLocker encryption, despite Soup never manually turning the feature on.

Unaware that Windows 11 automatically encrypts drives linked to a Microsoft account, Soup didn’t have the necessary BitLocker recovery keys — keys they didn’t even know existed. Without them, the data became permanently inaccessible. Even professional data recovery software couldn’t help, since BitLocker’s encryption is designed to prevent unauthorized access.

Desperate, Soup reinstalled Windows again, only to face the same encryption prompt — this time for the boot drive. Thankfully, they noted down the new recovery key and regained access to Windows. Unfortunately, their D: and E: drives remained permanently locked. When Reddit users suggested checking Microsoft account settings, Soup confirmed that only the key for the main C: drive was listed there.

What makes this situation worse is that BitLocker doesn’t just risk unexpected data lockouts — it can also impact system performance. Previous testing has shown that the software-based version of BitLocker can reduce SSD read/write speeds by up to 45%, as the CPU must continuously encrypt and decrypt data. This slowdown could explain the lag Soup noticed before resetting their system.

It’s worth noting that hardware-based encryption (known as OPAL) performs much better but isn’t what Windows 11 enables automatically. Some users in the Reddit thread also mentioned that even small system changes — like altering boot order — can unexpectedly trigger BitLocker on Windows 11 Home, even with a local account.

Windows 10 doesn’t exhibit the same automatic encryption behavior, nor does upgrading from Windows 10 to 11. Unfortunately, in Soup’s case, there’s little left to do other than wipe the drives and start over.

To avoid similar disasters, users should check BitLocker settings immediately after setup, disable automatic encryption if desired, and securely back up recovery keys. Always maintain external backups of crucial data — because once BitLocker takes over without your knowledge, recovery may not be possible.

Amigo Mesh Network Empowers Protesters to Communicate During Blackouts

 

Researchers from City College of New York, Harvard University, and Johns Hopkins University have developed Amigo, a prototype mesh network specifically designed to maintain communication during political protests and internet blackouts imposed by authoritarian regimes. The system addresses critical failures in existing mesh network technology that have plagued protesters in countries like Myanmar, India, and Bangladesh, where governments routinely shut down internet connectivity to suppress civil unrest.

Traditional mesh networks create local area networks by connecting smartphones directly to each other, allowing users to bypass conventional wireless infrastructure. However, these systems have historically struggled with messages failing to deliver, appearing out of order, and leaking compromising metadata that allows authorities to trace users. The primary technical challenge occurs when networks experience strain, causing nodes to send redundant messages that flood and collapse the system.

Dynamic clique architecture

Amigo overcomes these limitations through an innovative approach that dynamically segments the network into geographical "cliques" with designated lead nodes. Within each clique, individual devices communicate only with their assigned leader, who then relays data to other lead nodes. This hierarchical structure dramatically reduces redundant messaging and prevents network congestion, resembling the clandestine cell systems historically used by resistance movements where members could only communicate through local anonymous leaders.

Advanced security features

Security represents another major innovation in Amigo's design. The system implements "outsider anonymity," making it impossible for bystanders or surveillance systems to detect that a group exists. It enables secure removal of compromised devices from encrypted groups, a persistent vulnerability in older mesh standards. Amigo incorporates forward secrecy, ensuring past communications remain secure even if encryption keys are compromised, and post-compromise security that automatically generates new keys when breaches are detected, effectively blocking intruders

Realistic movement modeling

Unlike previous mesh systems that treated users as randomly moving particles, Amigo integrates psychological crowd modeling based on sociological research. Graduate researcher Cora Ruiz discovered that people in protests move closer together, slower, and in synchronized patterns. This realistic movement modeling creates more stable communication patterns in dense, moving environments, preventing the misrouted messages that plagued earlier systems.

While designed for political activism, Amigo's applications extend to disaster recovery scenarios where communication infrastructure is destroyed. The technology could prove vital for first responders, citizens, and volunteers operating in devastated areas or remote regions without grid connectivity. Lead researcher Tushar Jois indicates the next phase involves working directly with activists and journalists to understand protester needs and test how the network functions as demonstrations evolve.

Europol Dismantles SIMCARTEL Network Behind Global Phishing and SIM Box Fraud Scheme

 

Europol has taken down a vast international cybercrime network responsible for orchestrating large-scale phishing, fraud, and identity theft operations through mobile network systems. The coordinated crackdown, codenamed “SIMCARTEL,” led to multiple arrests and the seizure of a massive infrastructure used to fuel telecom-based criminal activity across more than 80 countries. 

Investigators from Austria, Estonia, and Latvia spearheaded the probe, linking the criminal network to over 3,200 cases of fraud, including fake investment scams and emergency call frauds designed for quick financial gain. The financial toll of the operation reached approximately $5.3 million in Austria and $490,000 in Latvia, highlighting the global scale of the scheme. 

The coordinated action, conducted primarily on October 10 in Latvia, resulted in the arrest of seven suspects and the seizure of 1,200 SIM box devices loaded with nearly 40,000 active SIM cards. Authorities also discovered hundreds of thousands of unused SIM cards, along with five servers, two websites, and several luxury vehicles. Around $833,000 in funds across bank and cryptocurrency accounts were also frozen during the operation. 

According to Europol, the infrastructure was designed to mask the true identities and locations of perpetrators, allowing them to create fake social media and communication accounts for cybercrimes. “The network enabled criminals to establish fraudulent online profiles that concealed their real identity and were then used to carry out phishing and financial scams,” Europol said in a statement. 

Investigators have traced the network to over 49 million fake accounts believed to have been created and distributed by the suspects. These accounts were used in a range of crimes, including extortion, smuggling, and online marketplace scams, as well as fake investment and e-commerce schemes. 

The operation highlights the growing global threat of SIM farms—collections of SIM boxes that allow cybercriminals to automate scams, send spam, and commit fraud while remaining undetected by telecom providers. These systems have become a preferred tool for large-scale phishing and social engineering attacks worldwide. 

Just weeks earlier, the U.S. Secret Service dismantled a similar network in New York City, seizing over 300 servers and 100,000 SIM cards spread across several locations. 

Cybersecurity intelligence firm Unit 221B also issued a warning that SIM farms are rapidly multiplying and putting telecom providers, banks, and consumers at risk. “We’ve identified at least 200 SIM boxes operating across dozens of U.S. sites,” said Ben Coon, Chief Intelligence Officer at Unit 221B. 

While the SIMCARTEL takedown marks a major victory for law enforcement, Europol noted that investigations are still underway to uncover the full extent of the criminal infrastructure. Authorities emphasize that combating SIM box networks is essential to defending users against phishing, identity fraud, and telecom-based cyberattacks that continue to grow in sophistication and scale.
