Security experts are urgently warning about the vulnerability of thousands of Qlik Sense servers to potential ransomware attacks by the troubling Cactus group. Despite prior disclosures of vulnerabilities by Qlik, many organisations remain at risk due to unpatched systems.
Qlik, an eminent player in data visualisation and business intelligence, disclosed two critical vulnerabilities, known as CVE-2023-41266 and CVE-2023-41265, in August last year. These flaws, when exploited together, enable remote attackers to execute arbitrary code on vulnerable systems. Additionally, a subsequent disclosure in September, CVE-2023-48365, revealed a bypass of Qlik's initial fix, leaving systems vulnerable to exploitation.
Recent reports highlight the active exploitation of these vulnerabilities by the Cactus ransomware group to infiltrate target environments. Despite warnings from security vendors like Arctic Wolf, ongoing attacks persist. A recent scan by Fox-IT uncovered over 5,000 internet-accessible Qlik Sense servers, with a significant portion still vulnerable to exploitation.
Countries such as the US, Italy, Brazil, Netherlands, and Germany face a concerning number of vulnerable servers, elevating the risk for organisations in these regions. In response, security organisations like Fox-IT and the Dutch Institute for Vulnerability Disclosure (DIVD) have launched efforts under Project Melissa to disrupt Cactus group operations.
Upon identifying vulnerable servers, Fox-IT and DIVD have actively notified affected organisations, urging immediate action to mitigate the risk of a ransomware attack. Joining the effort, the ShadowServer Foundation emphasises the urgent need for remediation to prevent compromise.
To assist organisations in identifying potential compromise, specific indicators such as the presence of unusual font files, qle.ttf and qle.woff, have been highlighted. These files, not standard in Qlik Sense installations, may indicate unauthorised access or remnants of previous security incidents.
In recognizing the gravity of the situation, Fox-IT stressed the need for proactive measures to address the potential risks of ransomware attacks. These measures include promptly patching vulnerable systems to fix known security issues and conducting thorough security assessments to identify and resolve any existing weaknesses in the network infrastructure.
Additionally, organisations are encouraged to implement robust cybersecurity measures, such as deploying intrusion detection and prevention systems, enhancing network segmentation to limit the impact of potential breaches, and enforcing strong access controls to prevent unauthorised access to sensitive data.
Regular employee training and awareness programs play a crucial role in identifying and mitigating security risks, including phishing attacks or social engineering attempts. By educating employees about the latest cybersecurity threats and best practices, organisations can strengthen their overall security posture and reduce the risk of successful ransomware attacks.
Moreover, maintaining up-to-date backups of critical data is essential to ensure data integrity and facilitate recovery in the event of a ransomware attack. Organisations should establish a comprehensive backup strategy that includes regular backups, secure storage of backup data, and testing of backup restoration procedures to ensure their effectiveness.
Given these developments, the collective efforts of security organisations, alongside proactive measures by organisations, are critical in mitigating the risk posed by the Cactus ransomware group and similar threats.
Ransomware attacks are becoming increasingly costly for businesses, with a new study shedding light on just how damaging they can be. According to research from Sophos, a staggering 94% of organisations hit by ransomware in 2023 reported attempts by cybercriminals to compromise their backups. This alarming trend poses a significant threat to businesses, as compromised backups can lead to a doubling of ransom demands and payments compared to incidents where backups remain secure.
The impact is particularly severe for certain sectors, such as state and local government, the media, and the leisure and entertainment industry, where 99% of attacks attempted to compromise backups. Perhaps most concerning is the revelation that overall recovery costs can skyrocket when backups are compromised, with organisations facing recovery costs up to eight times higher than those whose backups remain unaffected.
To mitigate the risk of falling victim to ransomware attacks, businesses are urged to take proactive measures. First and foremost, it's essential to backup data frequently and store backups securely in a separate physical location, such as the cloud, to prevent them from being compromised alongside the main systems. Regularly testing the restoration process is also crucial to ensure backups are functional in the event of an attack.
Furthermore, securing backups with robust encryption and implementing layered defences to prevent unauthorised access is essential for ransomware defence. Vigilance against suspicious activity that could signal attackers attempting to access backups is also recommended.
While it's tempting to believe that your organisation won't be targeted by ransomware, the reality is that it's not a matter of if, but when. Therefore, taking proactive steps to secure backups and prepare for potential attacks is imperative for businesses of all sizes.

Dual ransomware attacks have become a new, alarming trend in a digital environment replete with cyber threats. Using this smart strategy, criminals target an institution twice, multiplying the potential harm and raising the ransom demands. The FBI's most recent findings have shed insight on the seriousness of this developing threat.
According to the FBI, these attacks have surged in recent months, leaving organizations scrambling to bolster their cybersecurity measures. Special Agent Scott Smith, who leads the FBI’s Cyber Division, warns, "Dual ransomware attacks are a game-changer. They represent a significant escalation in the tactics employed by cybercriminals."
One high-profile incident detailed in a report by Tech Monitor involved a multinational corporation falling victim to a dual ransomware attack. The first attack infiltrated the company's network, encrypting critical files and crippling operations. Just as the organization was working to recover, a second attack hit, targeting backup systems and leaving the company with no option but to negotiate with the criminals.
The Register’s report further emphasizes the severity of this threat. It reveals that criminal organizations are becoming increasingly organized and resourceful, collaborating across borders to execute these attacks. The report quotes cybersecurity expert Dr. Emily Chen, who states, "Dual ransomware attacks signify a new level of sophistication among cyber criminals. It's no longer a matter of if an organization will be targeted, but when."
The implications of dual ransomware attacks are far-reaching. Not only do they result in financial losses from ransoms paid, but they also lead to significant operational disruptions and damage to an organization's reputation. Moreover, the psychological toll on employees can be immense, as they grapple with the stress and uncertainty of such attacks.
To mitigate the risks posed by dual ransomware attacks, organizations must adopt a multi-layered approach to cybersecurity. This includes regular employee training, robust threat intelligence programs, and the implementation of advanced security technologies. Additionally, maintaining up-to-date backups and a well-defined incident response plan can be crucial in the event of an attack.
Ransomware attacks that involve two different strains of malware are becoming more common, a clear indication that cybercriminals are becoming more sophisticated and organized. Businesses must take the lead in bolstering their cybersecurity defenses.

The notorious Monti ransomware has made an ominous comeback and is now targeting government organizations. Recent reports from cybersecurity professionals indicate that this malware version has reappeared with a new and powerful encryptor, specifically targeting Linux-powered devices. The cybersecurity community has been shaken by this development, which has prompted increased vigilance and efforts to block its advancements.
The Monti ransomware first gained notoriety for its sophisticated tactics and high-profile targets. Over the years, it has undergone several transformations to enhance its capabilities and expand its reach. Its focus on government entities raises concerns about potential disruptions to critical services, sensitive data leaks, and economic implications.
Security researchers at Trend Micro have identified the ransomware's latest campaign, which involves a newly designed encryptor tailored to Linux-based systems. This adaptation showcases the malware operators' determination to exploit vulnerabilities in various environments, with a clear emphasis on government networks this time. The attackers deploy phishing emails and exploit software vulnerabilities to gain unauthorized access, underlining the importance of consistent software updates and employee training in cybersecurity best practices.
The ramifications of a successful Monti ransomware attack on government systems could be dire. It could lead to halted public services, jeopardized confidential information, and the potential compromise of national security. As the attackers continue to refine their techniques, the need for a multi-layered security approach becomes paramount. This includes robust firewalls, intrusion detection systems, regular data backups, and continuous monitoring to promptly identify and mitigate any potential breaches.
The Monti ransomware's resurgence serves as further evidence of how cyber dangers are always changing. Cybercriminals are broadening their objectives to include industries that house sensitive data and essential infrastructure in addition to enhancing their attack routes. In order to effectively stop the ransomware's comeback, government agencies, business enterprises, and cybersecurity specialists must work together to exchange threat intelligence, best practices, and preventative measures.
Security companies are working hard to investigate the ransomware's behavior, extract the decryption keys, and create solutions that might be able to mitigate its effects in response to this most recent threat. However, prevention is still the best course of action. Government organizations must prioritize cybersecurity by putting money into cutting-edge technology, doing frequent vulnerability scans, and encouraging a cybersecurity awareness culture among staff members.
Ransomware attacks have become a pressing concern for individuals, businesses, and governments worldwide. Cybercriminals are constantly evolving their tactics, and two significant trends that demand close monitoring are the rise of Ransomware-as-a-Service (RaaS) and the growing reliance on cryptocurrencies for ransom payments.
According to recent reports, ransomware attacks have become increasingly sophisticated due to the emergence of Ransomware-as-a-Service. This model allows even less experienced hackers to launch ransomware campaigns with ease. By using RaaS, malicious actors can purchase ready-to-use ransomware kits from more skilled developers, giving them access to advanced tools without the need for extensive technical knowledge. This trend has dramatically widened the scope of potential attackers, leading to a surge in ransomware incidents across the digital landscape.
The impact of Ransomware-as-a-Service is not limited to smaller-scale operations. It has enabled the creation of formidable cybercrime syndicates capable of orchestrating large-scale attacks on critical infrastructures and major corporations. As a result, businesses of all sizes must be vigilant in bolstering their cybersecurity measures to fend off these increasingly prevalent threats.
Furthermore, ransomware attackers are exploiting cryptocurrencies to anonymize their transactions and evade law enforcement. Cryptocurrencies, such as Bitcoin, have emerged as the preferred method of payment for ransoms due to their decentralized nature and pseudo-anonymous properties. Transactions carried out using cryptocurrencies are challenging to trace, making it difficult for authorities to identify and apprehend the criminals behind these attacks.
The use of cryptocurrencies in ransom payments also creates an additional layer of complexity for victims and law enforcement agencies. As transactions are conducted peer-to-peer, there is no central authority that can freeze or retrieve funds. Once the ransom is paid, it is often impossible to recover the funds, leaving victims with limited options for recourse.
One of the key aspects of tackling ransomware effectively is understanding the motivations and techniques employed by attackers. As cyber criminals adapt their strategies, organizations, and individuals must remain informed about the latest trends and statistics surrounding ransomware. By staying up-to-date, they can implement proactive measures to mitigate the risks associated with these evolving threats.
As an industry expert highlights, "The increase in Ransomware-as-a-Service offerings has democratized cybercrime, allowing more threat actors to participate and launch attacks. At the same time, the adoption of cryptocurrencies as the preferred payment method makes it imperative for organizations to invest in robust cybersecurity measures and maintain data backups to protect against potential ransomware attacks."
Collaboration between private businesses and law enforcement authorities is now essential in the face of the escalating ransomware threat. Sharing threat intelligence and best practices can be crucial to effectively battling ransomware and reducing its effects on both organizations and people.
Arms manufacturer Rheinmetall has recently confirmed that it fell victim to a ransomware attack orchestrated by the BlackBasta ransomware group. The cyberattack has caused significant disruption to the company's operations, including its arms production capabilities.
