Iranian Hackers Use Fake Norton Antivirus to Spread Windows Spyware

Iranian state-sponsored hackers are targeting dissidents, activists, and journalists using deceptive tactics, including malicious applications that impersonate reputable cybersecurity products like Norton Antivirus and KeePass. The FBI and UK authorities issued a warning about these hackers, who establish rapport with targets via social messaging platforms, posing as IT support or known contacts. They convince victims to download files that appear authentic, including AI video creation applications and other software. The spyware, named “Chosen Brick,” infects Windows PCs and has capabilities such as capturing screen content, recording audio, collecting message data, and downloading additional malware. The hackers have exploited this spyware to publish personal details of victims, increasing their harassment. The FBI advises potential victims on detecting the spyware and recommends enabling antivirus software, running regular scans, and avoiding unofficial downloads.

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.

Steam users cautioned as new free RPG hit with ‘do not play’ warning

GAMINGbible highlights a new free RPG called Adventurers Guild, developed by AG Studio, which features a whimsical fantasy world and gameplay elements reminiscent of popular franchises. However, the game has been criticized for not matching the vibrant visuals shown in its trailer, with players expressing skepticism about its authenticity. The Steam listing includes a personal email for customer service, raising further concerns. Reviews warn of potential scams, false advertising, and misleading marketing tactics, advising caution when considering the game. There is currently no evidence of malware, but players are urged to be vigilant.
China-Linked Hackers Exploit Chrome-Windows Zero-Day Chain to Deploy GRIMWEDGE

China-Linked Hackers Exploit Chrome-Windows Zero-Day Chain to Deploy GRIMWEDGE

A spear-phishing campaign linked to the Chinese threat actor UTA0560 targeted various NGOs on September 1, 2026, exploiting recently patched vulnerabilities in Google Chrome and Microsoft Windows. The campaign utilized a malicious JavaScript backdoor called GRIMWEDGE, which was deployed through a multi-stage exploit chain that involved three vulnerabilities: CVE-2026-85046, CVE-2026-87491, and CVE-2026-85880. The attack began with spear-phishing emails that led recipients to a vulnerable U.S.-based university website, allowing attackers to redirect users to their infrastructure. The exploit chain enabled arbitrary code execution and facilitated the deployment of GRIMWEDGE, which is capable of host reconnaissance, file and process management, command execution, and payload delivery. The initial payload was an executable named "msgbox.exe," which extracted a legitimate Windows binary and a malicious DLL called "wsc.dll." This DLL initiated a sideloading chain and contacted a command-and-control server for further instructions. GRIMWEDGE allows for several commands, including system reconnaissance, directory listing, file deletion, and command execution in a hidden window. It lacks built-in persistence or lateral movement mechanisms but provides a foothold for further exploitation. Concurrently, another Chinese threat actor, JungleBamboo (APT31), used the same exploit chain to deploy a loader named SUPERSTOMP, which installs a credential-stealing Chrome extension called LONGTALE. The simultaneous use of the exploit chain by multiple actors suggests potential sharing or sale of the exploit, raising concerns about patch-gap vulnerabilities that pose risks for exploitation campaigns.

One Click, Full Phone Access: Malicious Android Apps Raise Financial Fraud Risk

Malicious Android applications are being promoted through social media advertisements, particularly on platforms like Instagram and Facebook, posing significant risks to users. The Indian Cyber Crime Coordination Centre (I4C) has warned about deceptive apps advertised under names such as Night Play, Reloop, Kyss, Vimo, Rivo, Nezo, and Vixa, which often redirect users to pornographic websites to download APK files. These applications can exploit sensitive device permissions, leading to malware infections, unauthorized financial transactions, and various forms of cyber fraud. Users may be tricked into granting accessibility permissions that allow the malware to operate in the background and potentially install a VPN, rerouting internet traffic through servers controlled by attackers. Cybersecurity experts advise users to verify the legitimacy of applications before installation and to be cautious of permissions requested by unknown apps.
