The UK government's National Cyber Security Centre (NCSC) has issued a warning about ongoing Distributed Denial of Service (DDoS) attacks carried out by Russia-linked hacktivists. These attacks are targeting critical infrastructure and local government systems across the UK. The NCSC's alert, released on January 19, 2026, emphasizes the potential disruption these attacks can cause, putting essential services at risk. The government urges organizations to bolster their defenses against such incidents, highlighting that the threat remains persistent. This situation is particularly concerning as it could impact public safety and the functionality of vital services during times of crisis.

The U.K. government has issued a warning about ongoing attacks from Russian-aligned hacktivist groups that are targeting the country's critical infrastructure and local government entities. These attacks primarily involve disruptive denial-of-service (DDoS) tactics, which can overwhelm systems and render them inoperable. As these groups continue their campaigns, organizations may face significant operational challenges and potential data breaches. It’s crucial for affected entities to bolster their cybersecurity measures to mitigate the risks associated with these aggressive actions. The situation highlights a growing trend of politically motivated cyberattacks that can impact essential services and public safety.

The UK's National Cyber Security Centre (NCSC) has issued a warning about an increase in disruptive cyber attacks carried out by Russian hacktivists. These attacks are primarily targeting critical infrastructure across the UK, raising concerns about the potential for significant disruptions to essential services. The NCSC has not specified the exact organizations or sectors being targeted, but the implications could be serious for public safety and national security. As these attackers become more aggressive, organizations must remain vigilant and enhance their cybersecurity measures to prevent potential breaches. This development comes amid heightened geopolitical tensions, making it crucial for all sectors to be prepared for potential cyber threats.

Researchers have identified a cross-site scripting (XSS) vulnerability in the control panel of StealC malware, an infostealer that has been operating since at least 2023. This malware, which is sold as a service, targets and extracts sensitive information like cookies and passwords from victims. The flaw in the control panel has exposed important details about the attackers behind the malware, raising concerns about the ongoing threat to users' data security. Since its update to StealC v2 in 2025, the malware has continued to pose risks to individuals and organizations alike. The discovery emphasizes the need for vigilance against such malware, as the information leak could lead to further malicious activities by the attackers.

A new information-stealing malware called 'SolyxImmortal' has emerged, which utilizes legitimate APIs and libraries to gather sensitive data. The malware sends this stolen information to Discord webhooks, making detection challenging. This type of attack can affect anyone who unwittingly downloads the malware, potentially compromising personal and financial information. As cybercriminals increasingly exploit trusted platforms and tools, users need to be vigilant about the software they install and the permissions they grant. This incident serves as a reminder of the evolving tactics used by attackers to bypass security measures.

This week, several significant cybersecurity incidents have emerged, showcasing the vulnerabilities within various systems. Notably, flaws in Fortinet products have come to light, potentially exposing users to exploitation. Additionally, researchers have identified the RedLine Clipjack malware, which can hijack browser sessions, affecting users who may not realize their data is being compromised. The discovery of a method to crack NTLM authentication raises concerns for organizations relying on this protocol, as it could lead to unauthorized access. Furthermore, a new attack targeting AI tools like Copilot illustrates how these advancements can be manipulated, posing risks to users and their data. These incidents emphasize the need for robust security measures as technology continues to evolve rapidly.

Researchers from Resecurity have uncovered a new malware called PDFSIDER that takes advantage of the legitimate PDF24 application to steal sensitive data and provide attackers with remote access to compromised systems. This malware is part of a sophisticated campaign targeting corporate networks, utilizing spear-phishing tactics to lure victims and encrypted communications to evade detection. Companies using PDF24 should be particularly vigilant as this attack leverages a trusted application, making it easier for attackers to bypass security measures. The implications are serious, as this could lead to significant data breaches and unauthorized access to sensitive corporate information.

Ukrainian authorities recently conducted a raid targeting individuals linked to the Black Basta ransomware group, a notorious criminal organization responsible for various cyberattacks. Among those arrested was Oleg Evgenievich Nefedov, who is believed to be one of the group's founders and has been placed on both Europol’s and Interpol’s Most Wanted lists. Black Basta has gained notoriety for deploying ransomware that encrypts victims' files and demands a ransom for their release. The group's activities have affected numerous businesses and organizations worldwide, raising concerns about the growing threat posed by such cybercriminals. This operation underscores the ongoing efforts by law enforcement to combat ransomware and bring perpetrators to justice.
