Posted by Adam Gavish, Google GenAI Security TeamWith the rapid adoption of generative AI, a new wave of threats is emerging across the industry with the aim of manipulating the AI systems themselves. One such emerging attack vector is indirect prompt injections. Unlike direct prompt injections, where an attacker directly inputs malicious commands into a prompt, indirect prompt injections involve hidden malicious instructions within external data sources. These may include emails, documents, or…
Across the larger cybersecurity community, an often-used adage is that “threat actors always change their tactics.” However, when we really start to look at and track incident data, we begin to see that while some changes may be necessitated based on infrastructures and other challenges the threat actor may encounter, there are times when tactics remain consistent across incidents. Recent investigations into exploitation activity for CVE-2025-31151 and CVE-2025-30406 show similar TTPs across di…

How to best empower your business clients’ cybersecurity with critical cyber threat intelligence
This blog post provides a detailed look at the TTPs of a ransomware affiliate operator. In this case, the endpoint had been moved to another infrastructure (as illustrated by various command lines, and confirmed by the partner), so while Huntress SOC analysts reported the activity to the partner, no Huntress customer was impacted by the ransomware deployment.
Evidence of a pre-existing exploit was rendered when the Huntress agent was added to an endpoint. Within minutes, and in part through the use of previously published threat intelligence, analysts were able to identify the issue and make recommendations to the customer to remediate the root cause.
