Outpost24 analysts recently discovered a critical authentication bypass vulnerability in CrushFTP, identified as CVE-2025-31161. The vulnerability has a CVSSv3.1 score of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (9.8). We reached out to MITRE for a CVE on 13th March 2025 and were within an agreed 90-day non-disclosure period with CrushFTP.

Secret doesn’t always mean safe – and it can even give a false sense of security.

On January 14th, 2025, Belsen Group emerged in the underground forum Breach Forums publishing a list of sensitive data extracted from vulnerable Fortinet FortiGate devices. Since then, they have expanded their malicious activities into acting as initial access brokers. Who are they and what do we know about them? In this blog we’ll give you the lowdown on an ambitious new threat group to be aware of.

In the context of penetration (pen) testing, false positives are where the testing tools or methods identify a security vulnerability or issue that doesn’t actually exist. Essentially, a false alarm. This can happen for a few reasons, such as misconfigurations in the testing tools, incorrect assumptions, or environmental factors.
