The first bug is tracked as CVE-2026-23863, a Windows specific problem. This bug was maliciously crafted with hidden “NUL BYTES” hidden within the filename, to trick WhatsApp into showing it as one filetype such as an authorized PDF while pretending to be running as an executable once opened. Meta fixed this patch in April on both platforms.
The second vulnerability, tracked as CVE-2026-23866 impacted both android and iOS users. The attack tactic involved partial authorization of AI rich response texts for Instagram Reels shared within Whatsapp. A threat actor could possible launch another user’s device to access media content through an arbitrary URL, such as launching OS level custom URL scheme handles. This flaw was patched in April on both platforms.
The two bugs were given medium severity by researchers. WhatsApp has verified that no bug was abused.
Both were rated medium severity, and WhatsApp confirmed there's no evidence either was actually abused.
These kind of reporting get sidelined by glossy and infamous threat. For instance the recent SMS pumpoing attacks increasing phone bills, or phishing campaigns that used messaging apps as entry points, and lastly the attack on educational institutes that compromised Canvas and Instructure, leaking hundreds of GBs of data.
But Whatsapp did a good job in finding and fixing the flaw before cybercriminals could exploit them and cause harm. The bug bounty program of WhatsApp has been going on for fifteen yesr, and the recent patches show it it is still reliable.
Simple advice: always keep your phones and app updated.
There has never been a better moment to use secure communications services like WhatsApp or Signal. The truth is that Meta does a great job of keeping the app and its users safe and secure, despite some security concerns of its own, such as the recently reported phishing attempts using the encrypted messenger as part of the exploit chain and a spyware threat targeting iOS users.
Security researchers have uncovered a gap in the way Anthropic Skill scanning tools inspect third-party AI packages, allowing malicious code hidden inside test files to execute on developer systems even after scanners marked the Skills as safe.
The issue centers on Anthropic Skills, reusable packages designed for AI coding assistants such as Claude Code, Cursor, and Windsurf. These packages often include instructions, scripts, and configuration files that help AI agents perform development tasks inside IDE environments.
Researchers from Gecko Security found that existing Skill scanners focus primarily on files tied directly to agent behavior, particularly SKILL.md, while ignoring bundled test files that can still run locally through standard developer tooling.
In the demonstrated attack chain, a Skill passed all scanner checks because its visible instruction files contained no prompt injection attempts, suspicious shell commands, or malicious instructions. However, the repository also included a hidden .test.ts file stored elsewhere in the directory structure. Although the file was outside the agent execution layer, it still executed through the project’s testing framework with full access to local resources.
According to researcher Jeevan Jutla, the problem begins when developers install a Skill using the npx skills add command. The installer copies nearly the entire repository into the project’s .agents/skills/ directory. Only a few items, including .git, metadata.json, and files prefixed with underscores, are excluded during installation.
Once placed inside the repository, testing frameworks such as Jest and Vitest automatically discover matching test files through recursive glob patterns. Both frameworks reportedly enable the dot:true option, allowing them to search inside hidden directories including .agents/. Mocha follows similar recursive discovery behavior in many default configurations.
A malicious Skill can therefore include a file such as reviewer.test.ts containing a beforeAll function that silently executes before visible tests begin. Researchers said these payloads can access environment variables, .env files, SSH keys, AWS credentials, deployment tokens, and other sensitive information commonly available inside local developer environments and CI pipelines. The data can then be transmitted to external servers without triggering obvious warnings during test execution.
The researchers stressed that the AI agent itself is never involved in the compromise. Instead, the malicious behavior occurs through trusted developer tooling already integrated into the software workflow. Existing scanners inspect the files the AI agent can interpret, but not the files executed separately by testing infrastructure.
The technique resembles older software supply-chain attacks involving malicious npm postinstall scripts and poisoned pytest plugins. However, Gecko Security noted that the Anthropic Skill ecosystem creates an additional propagation problem because installed Skills are often committed into shared repositories so teams can reuse them collaboratively.
GitHub’s default .gitignore templates do not automatically exclude .agents/ directories. Once a malicious test file enters the repository, every teammate cloning the project and every CI pipeline running automated tests may execute the payload across branches, forks, and deployment workflows.
The findings arrived shortly after multiple large-scale security audits examining the broader Anthropic Skills ecosystem. A January academic study named SkillScan analyzed 31,132 Skills collected from two major marketplaces and found that 26.1% contained at least one vulnerability spanning 14 separate patterns. Data exfiltration appeared in 13.3% of examined Skills, while privilege escalation appeared in 11.8%. Researchers also determined that Skills bundling executable scripts were 2.12 times more likely to contain vulnerabilities than instruction-only packages.
Several weeks later, Snyk published its ToxicSkills audit covering 3,984 Skills from ClawHub and skills.sh. The company reported that 13.4% of scanned Skills contained at least one critical-level security issue. Automated analysis combined with human review identified 76 confirmed malicious payloads, while eight malicious Skills reportedly remained publicly accessible on ClawHub when the findings were released.
In April, Cisco introduced an AI Agent Security Scanner integrated into IDE platforms including VS Code, Cursor, and Windsurf. The scanner can detect prompt injection attempts, suspicious shell execution patterns, and data exfiltration behaviors within Skill definitions and agent-referenced scripts. However, Gecko Security said bundled test files remain outside the scanner’s documented detection surface because the tool was designed around agent interaction layers rather than developer execution layers.
Researchers noted that other products, including Snyk Agent Scan and VirusTotal Code Insight, face similar structural limitations. These tools inspect what the agent is instructed to execute but may overlook code paths triggered separately through local development frameworks.
Elia Zaitsev described the broader issue as a distinction between interpreting intent and monitoring actual execution behavior. In this case, the malicious code did not depend on prompt manipulation or AI instructions. It operated as ordinary TypeScript executed through legitimate test runners with full local permissions.
Zaitsev also warned that enterprise AI agents increasingly operate with privileged access to OAuth tokens, API keys, and centralized data sources. If those credentials are accessible through environment variables during automated testing, malicious test payloads can reach sensitive infrastructure without requiring direct agent compromise.
Mike Riemer added that threat actors frequently reverse engineer security patches within 72 hours of release, while many organizations take far longer to deploy fixes. In the case of the Anthropic Skill test-file issue, researchers warned that the exposure window becomes more difficult to manage because the malicious files may execute immediately after installation without triggering scanner alerts.
Security researchers are urging development teams to block test discovery inside .agents/ directories and inspect Skill repositories for files such as *.test.*, *.spec.*, conftest.py, __tests__/, and suspicious configuration scripts before merging code.
The report also recommends pinning Skill installations to verified commit hashes rather than installing the latest repository version. Researchers said this reduces the risk of attackers submitting clean repositories for scanner approval before later inserting malicious files. The approach aligns with guidance published in the OWASP Agentic Skills Top 10 project.
Organizations that already store Skills inside repositories are advised to audit existing .agents/ directories immediately, rotate exposed credentials if suspicious files are discovered, inspect CI logs for unexplained outbound network traffic, and review repository history to identify when potentially malicious files entered development pipelines.
The researchers additionally called on security vendors to provide greater transparency regarding which directories, execution surfaces, and file categories their scanners actually inspect. They argued that security teams evaluating Anthropic Skill scanners should verify whether products analyze bundled test files, build scripts, and CI configurations rather than focusing exclusively on prompt injection and agent instruction analysis.
The rising AI economy is bringing a new type of cybercrime. Cybercriminals are scamming AI firms by signing up for new accounts to steal tokens via computing power. The problem is getting worse, according to Patrick Collison, CEO of payment behemoth Stripe. The token hackers now amount for one in every six new customer subscriptions.
Experts said that the threat actors steal the tokens to later sell them on the dark web. ‘Token pilfering’ has plagued the cybersecurity world and is becoming quite expensive for AI startups to give free trials to potential customers.
It is not new for hackers to attack startups. With the AI economy rising, it has created fractures for hackers because with traditional software trials, a registration for an AI firm brings valuable tokens for compute power that hackers can sell later.
The most neglected subject in AI is token theft. Because they are using tokens at machine speed, these attackers can swiftly accrue enormous consumption bills that they never plan to pay and burn inference costs. This is one of the most frightening aspects of that.
In order to use the tokens for purposes unrelated to what the company is delivering or to resell them, token theft sometimes involves thieves creating many accounts at an AI company and across multiple firms. They always vanish after using up all of the tokens; Sands compared this swindle to those who "dine and dash" at restaurants.
The problem surfaces as the crooks use agents to steal the tokens in minutes. Unlike a traditional software company, the cybercrime happens too fast for the organization to address the issue.
It is hell for AI firms who want to give out free trials to get more new users. Typically, it costs nothing for a firm to give out free trials on a temporary basis, but for AI firms, the customer-acquisition costs can go up to $500 due to scammers abusing the startup policies of giving out free tokens for trial accounts.
The token epidemic has created problems for startups. Few have stopped free trials, but it has affected their growth as it shuts down the opportunities to get new customers.
Luckily, one solution exists. According to Stripe, there exists a product called Radar that works as a default fraud detector in the credit card payment network, adapts tools, and helps clients find and block token fraud.
Project Eleven, a quantum security firm, published a report that said these quantum computers, even one, is powerful enough to hack the elliptic curve digital signatures securing Ethereum, Bitcoin, and other big blockchains. Experts say they won’t exist beyond 2033, and may end soon by 2030. The window for action is closing fast. According to the report, “Migration to quantum-resistant cryptography is no longer optional but imperative for any blockchain system expected to be trusted and secure into the future."
Recent innovations have significantly lowered the hardware bar needed to launch such attacks. A breakthrough Google paper said that breaking the elliptic curve cryptography threshold could be achieved within 1,200 logical cubits, and less than 90 minutes of computing time on a supercomputing hardware.
Google has put a Q-Day (like D-day) at 2032. Project Eleven’s research has decreased the timeline by two years: 2030. The report estimates that 6.9 million Bitcoin (one third of the total estimated supply) have already been leaked on-chain, exposed to the potential quantum attack. For ETH, exposure is more, with over 65% of all ETH held in quantum-exposed addresses.
The public ledgers and bearer-instruments offer no security. Blockchains has no scam department, no redressal platform for stolen funds, and no chargeback measures. If a quantum hacker recovers a private key and steals money, the loss is permanent. The transition problem is further fouled by slow-moving blockchain governance.
What makes blockchains particularly vulnerable, the report explains, is that their public ledgers and bearer-instrument design offer no safety net. Unlike a bank, a blockchain has no fraud department, no chargeback mechanism, and no way to reverse a forged transaction. Once a quantum attacker recovers a private key and drains a wallet, the loss is permanent.
Bitcoin SegWit upgrade took more than two years to complete whereas ETH’s transition of proof stake took around 6 years to build. Quantum migration reaches the most basic layer of any blockchain mechanism.
The tech world has already started moving. More than half of web traffic (human) is currently post-quantum encrypted, Cloudflare data from December 2025 said.
The digital asset industry lacks preparedness. Crypto developers are suggesting various proposals but these plans will take years to execute while the threat is already brushing businesses and users.
"The internet has already moved," the report added. "The digital asset industry—which arguably has more at stake because blockchains directly protect bearer value with the exact cryptographic primitives that quantum computers threaten—has barely started."
Cybersecurity entered 2026 under stress to deploy AI tech while building foundations for a quantum future. Cybersecurity experts have to defend against advanced AI and hybrid attacks while facing talent scarcity, a rapidly shifting threat scenario, and rising operational challenges.
It is the first time that hackers have access to the same advanced enterprise-level tech that security experts are using to defend their digital assets.
Organizations are in need of the transformational advantage that Quantum computing promises, however, it also risks affecting the cryptographic infrastructure that protects today’s digital world. Worse, cyber attackers are getting together and outbeating experts.
Like experts, threat actors don’t mind playing the long game either, they gain initial access and stay hidden inside systems for longer periods of time. When the right opportunity arrives, they move laterally and hack important data that can affect operations, cause financial damage, and tarnish reputations.
So, what are these four key areas that businesses and users need to address or stay safe from?
As per the ICS2 2025 report, 69% respondents suffered multiple cybersecurity breaches due to skill gaps. This is due to various factors such as budget constraints, misalignment in academia, and high enterprise demand.
Hackers use GenAI to advance their attacks, scaling, and escape security experts. This reactive cycle delays response times, and gives just basic protection. What businesses need today is Continuous Threat Exposure Management (CTEM) approach that offers real-time visibility before flaws can be exploited. But the success depends on AI-based risk prioritization.
Reliability is the new attack vector. Deepfakes have plagued every digital aspect of human life. Traditional measures fail to address content due to AI, therefore AI-based protection is needed. Adaptive deepfake systems can address identity workflows and respond immediately to threats, flagging malicious activity and capturing attacks with detailed metadata for research and audit work.
Quantum computing is making strides in applicability; if sufficiently advanced, the systems can break public-key cryptographic systems in ransomware attacks such as RSA, where hackers extort millions. Hackers are already using the “harvest now, decrypt later” approach, stealing coded data with no promise of returning it.
Thus, the National Institute of Standards and Technology (NIST) have advised to adopt post-quantum cryptography (PQC) and tracking quantum-vulnerable assets.
To be safe, users should avoid feeding personal data to the AI, as it can be misused, and there are thousands of cases now. Users at the receiver end can not do much except using multifactor authentication, and creating a strong password and using two-factor authentication. But users can be happy now that a new feature is available to individual ChatGPT users.
The new feature is called Advanced Account Security, it aims to provide better security to your account and protect your data. The option is aimed for security-minded users like journalists, politicians, activists, and researchers.
With better security, Advanced Account Security provides four setting standards. The first one requires using a passkey or physical security key to log in. The second one requires better tactics to recover an account besides SMS or email authorization. In the third setting, our active session with an AI chatbot is limited to restrict its exposure. The fourth setting protects your chats from AI misuse.
1. Use passkeys to avoid unauthorized access. Advanced Account Security asks for signing in with a passkey. Users can set up either one or both, but will also have to create two authentication methods.
2. Two-factor authentication for securing your account will help in recovering lost data. However, SMS and Email authentication are vulnerable to attacks. Advanced Account Security disables these two methods, so users are sometimes helpless.
3. Try to shorten your login sessions. Longer sessions are more exposed to malware or cyberattacks.
4. Turn off AI training. ChatGPT uses your conversations for AI training and learns to be human. But this capability is a risk to user privacy.
Advanced Account Security protects users in Codex if they use it to make and fine tune their code. Currently, this feature is only available to paid and free ChatGPT users with their personal accounts. However, OpenAI has said it is planning to expand it to the enterprise public.
Advanced Account Security also protects you in Codex if you use it to develop and fine-tune your own code. For now, the feature is available to free and paid ChatGPT users with their own accounts. But OpenAI said it expects to expand it to the enterprise crowd.
Several European governments are trying to reduce their dependence on American software, cloud platforms, and digital infrastructure as debates around data control, political influence, and technological independence become more intense across the region.
The situation has exposed contradictions in Europe’s relationship with U.S. technology companies. Microsoft chief executive Satya Nadella has largely stayed away from the kind of political messaging often associated with Alex Karp. Despite this difference, France has started moving parts of its public systems away from Microsoft Windows while simultaneously renewing contracts linked to Palantir Technologies through its domestic intelligence agency.
This complicated approach shows how Europe is attempting to distance itself from American tech firms without fully breaking away from them. Many governments now believe that relying too heavily on foreign technology companies can also mean depending on foreign laws, political priorities, and corporate influence. Still, Europe’s response has not followed one common strategy, with many actions appearing fragmented or reactive.
Much of the debate intensified after the U.S. passed the CLOUD Act in 2018 during President Donald Trump’s first term. The law gives American authorities the ability to request data from U.S.-based technology companies even if that information is stored outside the United States. For European officials, this raised concerns that storing data inside Europe may no longer be enough to fully protect sensitive information from foreign legal access.
Healthcare data quickly became one of the strongest examples used in these discussions. Medical records are considered among the most sensitive forms of information governments hold because they contain deeply personal details tied to citizens. Even after the CLOUD Act came into force, the United Kingdom partnered with companies including Google, Microsoft, and Palantir Technologies during the COVID-19 pandemic for projects involving National Health Service data.
Critics have argued that such partnerships could expose public-sector information to outside influence. France later decided that its Health Data Hub would stop using Microsoft Azure infrastructure and move toward what officials described as a sovereign cloud model. The contract was awarded to Scaleway, a cloud provider owned by French telecommunications group Iliad. Scaleway has also been expanding its network of data centers across Europe.
Scaleway later became one of four companies selected in a €180 million sovereign cloud contract backed by the European Commission. The program is intended to support cloud services that operate under European legal and regulatory standards. Notably, the European Sovereign Cloud initiative launched by Amazon Web Services was not included among the selected providers, even though Amazon created the project to answer European concerns about digital sovereignty.
Questions have also emerged around whether some so-called sovereign alternatives remain partly tied to American technology companies underneath. Some observers pointed to S3NS, a joint venture involving French defense company Thales Group and Google Cloud. Critics worry that arrangements like these could still leave room for indirect U.S. access or legal exposure despite being promoted as trusted European solutions.
Europe has faced similar problems in the search engine market. French search company Qwant was previously recommended for public servants in France while relying on Microsoft Bing’s underlying search infrastructure. The relationship later deteriorated after Qwant accused Microsoft of taking advantage of its dominant position in the market. Although French regulators declined to act against Microsoft, Qwant eventually started searching for alternatives on its own.
Qwant later partnered with German nonprofit search platform Ecosia to launch Staan, a Europe-based search index designed to reduce reliance on Google and Bing technologies. The project focuses on privacy and regional control over search infrastructure. Even so, both companies remain far smaller than their American competitors. Ecosia, despite having around 20 million users, still operates on a completely different scale compared to Google’s global user base.
One of the biggest problems facing European technology firms is market dominance from American companies. U.S. providers continue to control large parts of cloud computing, enterprise software, internet search, and artificial intelligence markets because of their global infrastructure, financial resources, and established ecosystems. European officials hope that large public-sector contracts could help regional providers compete more effectively.
Besides Scaleway, the European Commission’s sovereign cloud program also selected French companies Clever Cloud and OVHcloud, along with STACKIT. STACKIT was developed by the Schwarz Group, the parent company of Lidl, originally for its own internal systems before later being turned into a commercial cloud service.
Supporters of the initiative believe government-backed contracts could encourage more European companies to invest in domestic infrastructure instead of depending on foreign cloud providers. Backers of the program have also said the project aims to encourage digital solutions that align with European laws, governance rules, and privacy standards.
Still, Europe’s strategy of distributing contracts across several companies may create another challenge. While diversification could reduce dependence on one dominant provider and improve resilience, it may also make it harder for Europe to build a single technology giant capable of competing globally with firms such as Microsoft, Amazon, or Google.
Some critics also view sovereign tech partly as an economic strategy meant to keep European spending within the region. However, Europe’s attempts to move away from U.S. technology have not always translated into direct support for startups. In several cases, governments have instead turned toward open-source software alternatives.
France has already started replacing parts of its Windows-based systems with Linux. Public institutions in Germany, Denmark, Austria, and Italy are also exploring alternatives to Microsoft’s office software products through platforms such as LibreOffice.
Several governments have also embraced a “build instead of buy” approach by creating internal software tools. That strategy has faced criticism from parts of the technology and financial sectors. France’s Court of Auditors reportedly questioned spending linked to Visio, an internally developed platform intended to act as an alternative to Zoom and Microsoft Teams.
French newspaper Les Echos also reported frustration from parts of the country’s technology sector. Some critics argued that if governments themselves do not consistently adopt domestic technology tools, it becomes difficult to convince large private companies to do the same.
Many giants of European businesses continue selecting American technology providers when they offer stronger technical or commercial advantages. German airline Lufthansa chose Starlink for onboard internet services. Air France also selected Starlink despite partial ownership ties to the French and Dutch governments. Reports have additionally suggested that France’s national railway operator SNCF may eventually adopt similar services.
The debate around European alternatives has become particularly visible in satellite communications. During a disagreement involving Poland, Elon Musk stated publicly that “there is no substitute for Starlink.” European governments are now trying to prove otherwise by investing in domestic telecommunications and space infrastructure projects.
Public sentiment has also started influencing the discussion. After President Trump threatened to take control of Greenland, applications encouraging consumers to boycott American products surged in popularity on Denmark’s App Store rankings. The reaction showed that calls to reduce dependence on U.S. companies are no longer limited to policymakers and regulators.
Pressure is also building on European governments to reconsider contracts involving controversial American firms. Palantir’s recent public messaging and political positioning have drawn criticism inside parts of the European Union and the United Kingdom. At the same time, many European officials and citizens have started distancing themselves from X, formerly Twitter, because of growing dissatisfaction around platform governance and political discourse.
American technology companies have also shown that Europe is not always their top commercial priority. When Meta delayed the European release of Threads because of regulatory concerns tied to EU laws, it reinforced the perception that large U.S. firms can afford to deprioritize the region when legal requirements become too restrictive.
At the same time, this environment is opening new opportunities for companies building products specifically designed for European markets, languages, and legal standards. Supporters of the EuroStack initiative are pushing for rules that would encourage or require public institutions to purchase locally developed technology whenever possible.
Backers of sovereign tech also hope European companies can eventually compete internationally rather than only within domestic markets. French artificial intelligence company Mistral AI has reportedly experienced strong revenue growth as some businesses search for alternatives to OpenAI. Meanwhile, the governments of Canada and Germany are supporting cooperation between Cohere and Aleph Alpha to create what supporters describe as a transatlantic AI platform for governments and businesses.
As geopolitical tensions continue reshaping the global technology industry, some companies are discovering that not being American, Chinese, or Russian is itself becoming a commercial advantage in international markets.
