Chinese state security authorities warn outdated antivirus software can expose systems to cyberattack

Chinese state security officials have emphasized the necessity for organizations to keep antivirus software and virus databases updated to prevent data breaches and unauthorized access. The Ministry of State Security (MSS) highlighted that neglecting these updates has led to significant security incidents, including the theft of sensitive data and cyberattacks on work email accounts. Specific cases include a research institute that suffered a breach due to unpatched vulnerabilities, an institution exposed to cyberattacks for not enforcing regular virus scans, and a company that operated a poorly protected server with outdated antivirus software. Contributing factors to delayed updates include a lack of awareness about cybersecurity risks, insufficient network maintenance, and unclear responsibilities within organizations. Under China's Cybersecurity Law, network operators must implement measures to protect against cybersecurity threats. The MSS advises organizations to enhance their cybersecurity measures by adopting technologies like automated risk alerts and intelligent behavioral analysis.

Iranian spies hit Windows machines with Chosen Brick data-stealing malware

Iranian state cyber actors are targeting individuals through popular messaging applications, using surveillance and data-stealing malware known as "Chosen Brick," which has been in use since at least 2025. This malware is designed for Windows systems and enables the theft of personal data, allowing Iranian spies to monitor perceived threats such as dissidents, activists, and journalists. The attacks typically begin with messages sent via WhatsApp or Telegram, impersonating trusted contacts. Attackers conduct extensive research on their targets to craft convincing messages that encourage victims to download malicious files disguised as legitimate applications. Once executed, Chosen Brick operates stealthily, evading detection and establishing a connection for command-and-control communications. It can enumerate processes, capture screen and audio content, extract sensitive information, and even wipe infected systems. Organizations suspecting compromise are advised to engage IT providers for investigations and to inform staff about potential risks. Recent alerts follow cyberattacks on water and energy sectors linked to Iran, with ongoing concerns about the implications for cybersecurity amid escalating military tensions. Additionally, five US agencies have reported that attackers are using AI-generated scripts to exploit vulnerabilities in critical infrastructure systems.

AI Is Changing Antivirus From File Matching to Behaviour-Based Malware Detection

Artificial intelligence is transforming malware detection by moving away from traditional file signature reliance to analyzing program actions. Antivirus software previously used signatures to identify known threats, but the rapid emergence of over 450,000 new malware samples daily complicates this method. Attackers now employ techniques like repacking and encryption to evade detection, prompting the need for machine-learning and behavioral techniques for better protection. Modern detection systems assess multiple characteristics of executable files, including their behavior, to identify potential threats, even if they lack recognized signatures. Microsoft's Project Ire exemplifies advanced detection capabilities, functioning as an automated malware analyst that evaluates unknown binaries based on their behavior. Additionally, modern endpoint-security products leverage cloud systems to analyze data from multiple devices, enhancing threat detection through shared intelligence. However, AI detection can still produce false positives and is susceptible to manipulation by attackers. Therefore, effective security systems require a combination of traditional measures, behavioral monitoring, machine learning, and human analysis to navigate complex threats.
