Posted by Thomas Brunner, Yu-Han Liu, Moni PandeAt Google, our Threat Intelligence teams are dedicated to staying ahead of real-world adversarial activity, proactively monitoring emerging threats before they can impact users. Right now, Indirect Prompt Injection (IPI) is a top priority for the security community, anticipating it as a primary attack vector for adversaries to target and compromise AI agents. But while the danger of IPI is widely discussed, are threat actors actually exploiting th…
Written by: JP Glab, Tufail Ahmed, Josh Kelley, Muhammad Umair Introduction Google Threat Intelligence Group (GTIG) identified a multistage intrusion campaign by a newly tracked threat group, UNC6692, that leveraged persistent social engineering, a custom modular malware suite, and deft pivoting inside the victim’s environment to achieve deep network penetration. As with many other intrusions in recent years, UNC6692 relied heavily on impersonating IT helpdesk employees, convincing their victim…
Standard EDR creates a gap between detection and action. Huntress closes it. Learn how our Attack Disruption Engine automatically disrupts threat actors and reduces the impact of endpoint attacks.
Introduction Advances in AI model-powered exploitation have demonstrated that general-purpose AI models can excel at vulnerability discovery, even without being purpose-built for the task. Eventually, capabilities such as these will be integrated directly into the development cycle, and code will be more difficult to exploit than ever; however, this transition creates a critical window of risk. As we harden existing software with AI, threat actors will use it to discover and exploit novel vulne…
Written by: Jamie Collier, Robin Grunewald Germany has reclaimed its position as a primary focus for cyber extortion in Europe. While data leak site (DLS) posts rose almost 50% globally in 2025, Google Threat Intelligence (GTI) data shows that the surge is hitting German infrastructure harder and faster than its regional neighbors, marking a significant return to the high-pressure levels previously observed in the country during 2022 and 2023. Cyber Criminals Pivoting Back to Germany Germany mo…
Posted by Ben Ackerman, Chrome team, Daniel Rubery, Chrome team and Guillaume Ehinger, Google Account Security team Following our April 2024 announcement, Device Bound Session Credentials (DBSC) is now entering public availability for Windows users on Chrome 146, and expanding to macOS in an upcoming Chrome release. This project represents a significant step forward in our ongoing efforts to combat session theft, which remains a prevalent threat in the modern security landscape. Session theft t…
A threat actor enumerated our entire AD with Get-ADComputer, and none of our detections fired. The problem wasn't their evasion - it was an architectural blind spot in how PowerShell talks to Active Directory.
Discover how North Korean threat actors use synthetic identities, AI-assisted workflows, and overlapping infrastructure to infiltrate companies, and learn actionable strategies to mitigate this insider threat.
Threat actors are using AI to supercharge tried-and-tested TTPs. When attacks move this fast, cyber-defenders need to rethink their own strategy.
Group-IB researchers uncover an ongoing phishing campaign targeting major banks in the Philippines. This blog details how threat actors abuse trusted and legitimate platforms to deceive users and evade detection. It highlights a significant threat escalation with the successful hijacking of a legitimate domain to host malicious infrastructure, enabling threat actors to operate with even greater credibility and reduced detection.
Railway PaaS is being weaponized as a clean token replay engine in an active AiTM and device code phishing campaign impacting 268+ M365 organizations and 100+ MSPs.
Threat actors are people, too, and like everyone else, make mistakes. These mistakes can reveal insights into the threat actor, or even expose access to their infrastructure.
The abuse of remote monitoring and management (RMM) tools is surging. See how threat actors daisy chain RMM software for initial access, persistence, and detection evasion.

In this roundup, Tony looks at how opportunistic threat actors are taking advantage of weak authentication, unmanaged exposure, and popular AI tools
The business social networking site is a vast, publicly accessible database of corporate information. Don’t believe everyone on the site is who they say they are.
This blog uncovers DeadLock’s stealthy usage of Polygon smart contracts for proxy address storage, a poorly-documented and under-reported technique that Group-IB analysts have observed increased usage in the wild. Variants of this technique are very wide and offer great alternatives to threat actors for bypassing traditional defenses by abusing decentralized blockchains available worldwide.
