Iranian hackers use CHOSEN BRICK data-stealing malware to spy on dissidents and journalists

UK NCSC, FBI and Dutch AIVD warn Iranian state hackers deploy CHOSEN BRICK spyware via WhatsApp and Telegram lures against dissidents and journalists since 2025.

The UK's NCSC, the FBI and the Netherlands' AIVD jointly warned that Iranian state cyber actors have deployed CHOSEN BRICK against dissidents, activists and journalists in the UK, US and Netherlands since at least 2025. Victims are contacted on WhatsApp or Telegram by impostors posing as known contacts or platform support, then tricked into running files disguised as software such as fake Norton Antivirus, KeePass, Telegram or MRI scan results. The Windows malware adds Microsoft Defender exclusions, persists via HKCU Run keys, uses per-device Telegram bots for C2, and can capture screens, activate microphones, steal email and messaging data, and download further payloads. Some stolen data has later appeared on pro-Iranian leak sites, and the agencies note Iranian intelligence has plotted kidnappings or lethal operations against targets abroad.

Microsoft Releases Emergency Windows 11 Update Following Patch Tuesday Bugs

Microsoft issued emergency Windows 11 update KB5129195 to fix Patch Tuesday regressions and fully close the CVE-2026-62721 privilege escalation flaw.

Microsoft shipped out-of-band cumulative update KB5129195 for Windows 11 24H2 and 25H2 (builds 26100.9457 and 26200.9457) after the September 8 Patch Tuesday rollup, which addressed over 960 CVEs including two actively exploited flaws, broke Remote Desktop Services, Hyper-V Plan9 folder sharing, and USB audio. The emergency release also strengthens the incomplete fix for CVE-2026-62721, an elevation-of-privilege flaw in the Windows User-Mode Power Service that could let a local attacker gain SYSTEM privileges. Companion patches cover Windows 11 26H1, Windows 10, and Windows Server. Some USB Audio Class 1.0 and AMD Radeon graphics issues remain unresolved.

GhostCode Phishing Kit Bypasses Microsoft 365 MFA to Hijack Accounts in 78 Seconds

eSentire identified GhostCode, a phishing kit abusing Microsoft 365 OAuth device-code sign-in to steal tokens and take over accounts in seconds.

eSentire analysts identified GhostCode in late August, a phishing kit that uses business contact-form messages and an NDA pretext to deliver a password-protected HTML attachment leading victims to a Microsoft device-code sign-in. Victims authenticate on legitimate Microsoft pages, letting the kit obtain a Primary Refresh Token in 32 seconds and register three devices in 78 seconds, with residential proxies matching the victim's location. The kit hides its redirect with encrypted addresses, junk data, and scanner-filtering challenges, and uses GHOSTnet-linked infrastructure during device enrolment. eSentire recommends blocking device-code authentication via Conditional Access, invalidating tokens, and reviewing newly enrolled devices.
