Iranian cyber targeting of dissidents, activists and journalists
UK NCSC, FBI, and Dutch AIVD expose CHOSEN BRICK spyware used by Iranian state actors against dissidents, activists, and journalists worldwide.
A joint advisory from the UK NCSC, FBI, and Dutch AIVD details CHOSEN BRICK, a Windows spyware family used by Iranian state cyber actors since at least 2025 against dissidents, activists, and journalists in the UK, US, and Netherlands. Actors build rapport on WhatsApp and Telegram impersonating known contacts or platform support, then deliver disguised payloads resembling apps such as Telegram, Norton, RunwayML, or fake MRI results. The malware persists via HKCU Run registry keys, adds Microsoft Defender exclusions, and uses a unique Telegram bot C2 per victim. Capabilities include screen capture, microphone recording, process enumeration, email and messaging data theft, file deletion, and system wiping; victim data has appeared on pro-Iranian leak sites.

Smishing Triad Hackers Use JWR Phishing Kit to Steal Cards, OTPs and Bank Credentials
Group-IB attributes large-scale smishing using the JWR real-time phishing kit to the Smishing Triad's Outsider cluster, harvesting card data, OTPs, and bank credentials.
Group-IB attributes a large-scale SMS phishing campaign to Outsider, an operator sub-cluster within the Smishing Triad phishing-as-a-service ecosystem, using a kit dubbed JWR. The Vue 2-based platform maintains real-time WebSocket communication with operators, enabling them to adapt pages live and harvest roughly 70 PII fields, card data, PINs, OTPs, identity document images, and digital wallet credentials via a dedicated PayPal sub-funnel. Unit 42 previously tied 194,345 malicious domains across 136,933 root domains to the broader operation since January 2024. Defenders can hunt for /api/open/ endpoints, /webSocket/QT/ paths, JWR-prefixed storage artifacts, and a hard-coded WebSocket token.
