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…
Cloudflare is introducing scannable API tokens, enhanced OAuth visibility, and GA for resource-scoped permissions. These tools help developers implement a true least-privilege architecture while protecting against credential leakage.
We share Cloudflare's internal strategy for governing MCP using Access, AI Gateway, and MCP server portals. We also launch Code Mode to slash token costs and recommend new rules for detecting Shadow MCP in Cloudflare Gateway.
Managed OAuth for Cloudflare Access helps AI agents securely navigate internal applications. By adopting RFC 9728, agents can authenticate on behalf of users without using insecure service accounts.
Huntress uncovered a malware operation using signed PUP to deploy AV killers with SYSTEM privileges. Learn how this adware crosses the line into malware territory and how anyone could have hijacked their update mechanism.
Security programs are failing against modern identity threats. See new Huntress data to discover a roadmap to building a resilient security team.
Don’t forget to secure your side doors. Attackers look for the systems you treat as secondary. Don't neglect staging environments, as they’re a critical part of your attack surface.
Posted by Jiacheng Lu, Software Engineer, Google Pixel Team Google is continuously advancing the security of Pixel devices. We have been focusing on hardening the cellular baseband modem against exploitation. Recognizing the risks associated within the complex modem firmware, Pixel 9 shipped with mitigations against a range of memory-safety vulnerabilities. For Pixel 10, Google is advancing its proactive security measures further. Following our previous discussion on "Deploying Rust in Existing…

If you’ve been a victim of fraud, you’re likely already a lead on a ‘sucker list’ – and if you’re not careful, your ordeal may be about to get worse.
Following our April 2024 announcement, Device Bound Session Credentials (DBSC) is now entering public availability for Windows users on Chrome 146, and expanding to macO…
Attackers are already targeting the AI tools your team just started using. Here's what that looks like when it lands in your own environment. And what actually stops it.
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…
Event 1644 shows localhost, hiding the attacker's real IP. By correlating Event 5156 with a ~60-80ms timing window, you can attribute ADWS queries to their actual source—and the data was already in your SIEM.
Group-IB hosted the FIRST Technical Colloquium in Paris, where cybersecurity experts challenged assumptions around modern cyber defense. FIRST Chair Olivier Caleff opened and moderated the event.
Attackers count on static defenses. Switch to advanced behavioral analytics to spot abnormal behavior while its still unfolding and protect your environment.
CERT-EU Cyber Threat Landscape Report for 2025 - Year Review
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.
The Stryker incident revealed that a "Weaponized Remote Wipe" via compromised MDM is a more permanent and difficult threat than ransomware. Learn concrete steps to secure management platforms and prevent your security shield from becoming a weapon.
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.
Recent advances in quantum hardware and software have accelerated the timeline on which quantum attack might happen. Cloudflare is responding by moving our target for full post-quantum security to 2029.
A recent incident linked to the NightSpire ransomware workflow gives insight into why the RaaS structure and model, or lack thereof, are important – especially when it comes to scoping and recovering from the incident.
Threat actors are using AI to supercharge tried-and-tested TTPs. When attacks move this fast, cyber-defenders need to rethink their own strategy.
The rise of AI opens more doors to attackers

Posted by Adam Gavish, Google GenAI Security TeamIndirect prompt injection (IPI) is an evolving threat vector targeting users of complex AI applications with multiple data sources, such as Workspace with Gemini. This technique enables the attacker to influence the behavior of an LLM by injecting malicious instructions into the data or tools used by the LLM as it completes the user’s query. This may even be possible without any input directly from the user.IPI is not the kind of technical proble…
