Hackers Disguise CHOSEN BRICK Malware as AI Apps, Antivirus Software and MRI Results

Iranian state-affiliated cyber actors are targeting dissidents, activists, and journalists using fake AI applications, counterfeit antivirus tools, and fabricated MRI scan results, primarily through a spyware family known as CHOSEN BRICK, which is designed for Windows systems. This campaign has been active since at least 2025 and affects individuals globally, including in the UK, US, and Netherlands. The malware establishes persistence via the Windows Registry Run key and communicates through Telegram, utilizing unique Bot IDs for each victim. CHOSEN BRICK is capable of extensive data collection, including capturing screenshots, recording audio, and stealing email content. Personal information from victims has been found on pro-Iranian leak sites, increasing harassment risks. Security measures should include monitoring for suspicious Registry entries and unusual communications, while users are advised to avoid unsolicited software installations and keep their systems updated. The FBI refers to this malware family as HEAVYGRAM.

AI helps scammers build convincing antivirus renewal pages

Antivirus renewal scams often begin with messages claiming automatic subscription renewals, leading victims to counterfeit pages designed to collect personal information. These scams impersonate well-known brands and do not indicate that the sender has accessed the recipient's device. Responding to such messages can provide scammers with valuable data, including names and phone numbers, which can be sold or used for further scams. A specific scam site impersonating Avast targeted users in Belgium, falsely claiming a subscription renewal for €129.99. The site appeared polished and requested basic contact information without asking for sensitive data. It contained notes suggesting AI involvement in its creation, indicating it was a half-finished project. To identify antivirus renewal scams, individuals should verify any claimed charges directly with their bank, check subscriptions through official channels, be cautious of cancellation forms requesting phone numbers, treat follow-up calls as potential threats, and avoid installing remote access software. If engagement with a scam occurs, disconnect from the internet, remove any installed software, and change passwords. Tools like Malwarebytes Browser Guard can help block malicious sites, and Scam Guard can analyze suspicious communications.

Best Antivirus for Windows 2026: 5 to Install, 1 to Avoid

Windows is the only desktop platform where antivirus software is essential. Microsoft has patched many vulnerabilities, but the OS still allows installations from unverified sources and connects to potentially untrustworthy networks. As of 2026, the top antivirus solutions for Windows include: - Norton 360: Best overall, with a full scan time of 13 minutes and 22 seconds, robust firewall, and up to 250 GB cloud backup. - Bitdefender: Best for older PCs, maintaining peak CPU usage at 11% and memory at 183 MB during scans. - Avast One: Best free option for Windows 11, achieving a perfect score in AV-TEST. - NordVPN Threat Protection Pro: Best for VPN users, blocking 90% of malware. - McAfee+: Best for households with multiple devices, offering unlimited coverage but is the slowest scanner. - Microsoft Defender: Best free option included with Windows, awarded Top Product by AV-TEST. Norton 360 has a 99.8% detection rate and offers a 60-day refund window. Bitdefender also has a 99.8% detection rate with low resource usage. Avast's free version is effective, while NordVPN provides integrated malware protection for existing VPN users. McAfee is suitable for large households but has slower performance. Microsoft Defender is adequate for single users practicing safe browsing but lacks multi-device support. Kaspersky is unavailable in the U.S. due to supply chain concerns.

Android Advanced Protection to Roll Out Granular “Expert Features”: App Teardown

A new feature called "expert mode" is being introduced to enhance the "Advanced Protection" framework for Android users, allowing them to toggle specific security features individually. Users will be able to manage six distinct items within the Advanced Protection suite: Intrusion logging, USB protection, Block auto-connection to unsecured Wi-Fi, Unknown apps, Spam filter, and Suspicious links in Google Messages. The "expert features" will not replace "Advanced Protection" but will provide users with the option to enable all protections at once or selectively activate specific features. While "Block auto-connection to unsecured Wi-Fi" will debut with "expert features," the inclusion of "Unknown apps," "Spam filter," and "Suspicious links in Google Messages" in the final version remains uncertain. The relevant resource for updates is the "Google Play services" app, version v26.36, released on September 15, 2026.

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.

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.
