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.


Socksprox: Unleashing Bug Bounty Potential with AI and Kubernetes

Socksprox is a solution to common bug bounty hunting challenges, using a Kubernetes cluster with multiple Dante Socks Proxy nodes to bypass rate-limiting, avoid bans, and manage IP addresses. Developed with the help of ChatGPT, an AI language model, Socksprox demonstrates the potential of AI models to accelerate learning and development in technology. The scalable and cost-effective solution has great potential for enhancing bug bounty hunting and optimizing the experience for developers.

The patch improves the compatibility of the CLOUD 3700 F reader with the NFC library by implementing additional functions and updating the code. This change enhances communication and allows the reader to better support various NFC card types.


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.


Google's Threat Analysis Group (TAG) has discovered two campaigns using 0-day exploits against Android, iOS, and Chrome. These campaigns show that commercial spyware vendors have increased their capabilities and are enabling dangerous hacking tools to be utilized by governments. Both campaigns were limited and highly targeted, highlighting the importance of timely patching and keeping devices updated.
