ESET Research has discovered a new China-aligned APT group that we’ve named GopherWhisper, which targets Mongolian governmental institutions
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…
The resurgence of one of Russia’s most notorious APT groups
Huntress has identified and detailed a full timeline of an intrusion in a customer environment that aligns with what others have identified as MuddyWater (Iranian-linked APT).

The attack used a compromised mailbox to distribute Phoenix backdoor malware to international organizations and across the whole Middle East and North Africa region, targeting more than 100 government entities.
In July 2025, the Tea app 🔗, a mental health and social community platform, experienced a devastating breach that spilled 72,000 images (including 13,000 driver’s license and verification selfies) and over 1.1 million private direct messages onto the internet. The leaks first surfaced on 4chan and quickly spread across forums, torrents, and underground channels. This was not “just another API key leak.” Instead, it was a story about Firebase misconfigurations, poor data retention practices, an…
Huntress discovered RedCurl activity across several organizations in Canada going back to 2023. Learn more about how this APT operates and how they aim to remain undetected while exfiltrating sensitive data.
Explore the growing threats posed by the Lazarus Group's financially-driven campaign against developers. We will examine their recent Python scripts, including the CivetQ and BeaverTail malware variants, along with their updated versions in Windows and Python releases. Additionally, we will analyze their tactics, techniques, and indicators of compromise.
Huntress identified an intrusion against a non-profit supporting Vietnamese human rights that’s likely spanned years. Jump in as we provide a thorough analysis of this malicious threat actor.
