Description

A new zero-day vulnerability, CVE-2025-0282, in Ivanti Connect Secure VPN appliances has been exploited since mid-December 2024. The vulnerability allows unauthenticated remote code execution. Attackers have deployed multiple malware families, including SPAWN, DRYHOOK, and PHASEJAM, to maintain persistence, steal credentials, and evade detection. The attacks involve disabling security features, injecting web shells, blocking system upgrades, and performing network reconnaissance.

Ivanti has released patches and recommends customers use their Integrity Checker Tool and implement security measures.
