Detect and disrupt AI-themed attacks with Microsoft Defender

Microsoft Threat Intelligence reports criminal campaigns impersonating ChatGPT, Copilot, Claude, and DeepSeek in phishing, AiTM, and malvertising attacks reaching 100,000 emails daily.

Microsoft Threat Intelligence observed a growing set of campaigns that abuse trust in popular AI brands: a ChatGPT-themed phishing campaign sent up to 100,000 emails in one day to steal payment card data, and a Claude-themed campaign used adversary-in-the-middle techniques to harvest credentials and access tokens. Other campaigns included malvertising for a fake AI Windows plugin delivering the Vidar stealer and fraudulent DeepSeek installers distributed via GitHub. Initial access broker Storm-3075 used AI-themed malvertising to distribute payloads for multiple downstream actors, and Microsoft notes the AI services themselves were not compromised. Microsoft also details Defender protections such as Safe Links, Safe Attachments, and attack disruption against these multi-stage lures.

Latvian officials resign after cyberattack exposes data on 1.2 million people

Latvia's road traffic agency CSDD confirmed a breach exposing data on 1.2 million people and 200,000 businesses, prompting leadership resignations.

Latvia's Road Traffic Safety Directorate (CSDD) said hackers accessed payment receipt data dating back to 2008, covering over 1.2 million people and 200,000 legal entities, about two-thirds of Latvia's population. Stolen data includes personal ID numbers, license plates, payment amounts and addresses; phone numbers, emails and passwords were not affected. CERT.LV said attackers exploited a vulnerability in an internet-exposed CSDD system, and President Edgars Rinkevics called the breach a significant national security threat. The supervisory board resigned and chief Aivars Aksenoks said he will leave; state police opened criminal proceedings while responsibility with IT contractor Tet is disputed.
