The 3CX Supply Chain Debacle: Unraveling the 'Smooth Operator' Attack

The recent 3CX Voice Over Internet Protocol (VOIP) desktop client supply chain attack, dubbed "Smooth Operator," affected over 600,000 companies and 12 million users. North Korean-linked threat actor Labyrinth Chollima is the prime suspect. The attackers distributed a trojanized update, compromising both Windows and MacOS versions of the software, which then dropped an info-stealing payload. Despite early reports from users, 3CX's initial response was inadequate, dismissing the issue and instructing users to create security exceptions.

Beware the Trap: SNMP Exploit Leads to Remote Code Execution on LibreNMS

A critical security vulnerability has been discovered in LibreNMS, a popular open-source network monitoring solution. An unauthenticated attacker could exploit this vulnerability by sending a single SNMP trap, allowing them to execute arbitrary code remotely. The issue affects LibreNMS versions 22.10.0 and earlier, with a patch available in version 22.11.0. The article provides an in-depth explanation of SNMP, the vulnerability, and its impact, as well as key learnings and recommendations for securing SNMP configurations and using safer template engines.
