Apache ActiveMQ | Breaking Cybersecurity News | The Hacker News

Threat actors are exploiting a nearly two-year-old security flaw in Apache ActiveMQ to gain persistent access to cloud Linux systems and deploy malware called DripDropper . But in an unusual twist, the unknown attackers have been observed patching the exploited vulnerability after securing initial access to prevent further exploitation by other adversaries and evade detection, Red Canary said in a report shared with The Hacker News. "Follow-on adversary command-and-control (C2) tools varied by endpoint and included Sliver , and Cloudflare Tunnels to maintain covert command and control over the long term," researchers Christina Johns, Chris Brook, and Tyler Edmonds said. The attacks exploit a maximum-severity security flaw in Apache ActiveMQ ( CVE-2023-46604 , CVSS score: 10.0), a remote code execution vulnerability that could be exploited to run arbitrary shell commands. It was addressed in late October 2023. The security defect has since come under heavy exploitation...

Atlassian has released software fixes to address  four critical flaws  in its software that, if successfully exploited, could result in remote code execution. The list of vulnerabilities is below - CVE-2022-1471  (CVSS score: 9.8) - Deserialization vulnerability in  SnakeYAML library  that can lead to remote code execution in multiple products CVE-2023-22522  (CVSS score: 9.0) - Remote code execution vulnerability in Confluence Data Center and Confluence Server (affects all versions including and after 4.0.0) CVE-2023-22523  (CVSS score: 9.8) - Remote code execution vulnerability in Assets Discovery for Jira Service Management Cloud, Server, and Data Center (affects all versions up to but not including 3.2.0-cloud / 6.2.0 data center and server) CVE-2023-22524  (CVSS score: 9.6) - Remote code execution vulnerability in Atlassian Companion app for macOS (affects all versions up to but not including 2.0.0) Atlassian described CVE-2023-22522...

The recently disclosed critical security flaw impacting Apache ActiveMQ is being actively exploited by threat actors to distribute a new Go-based botnet called  GoTitan  as well as a .NET program known as  PrCtrl Rat  that's capable of remotely commandeering the infected hosts. The attacks involve the exploitation of a remote code execution bug (CVE-2023-46604, CVSS score: 10.0) that has been  weaponized  by various hacking crews, including the  Lazarus Group , in recent weeks. Following a successful breach, the threat actors have been observed to drop next-stage payloads from a remote server, one of which is GoTitan, a botnet designed for orchestrating distributed denial-of-service (DDoS) attacks via protocols such as HTTP, UDP, TCP, and TLS. "The attacker only provides binaries for x64 architectures, and the malware performs some checks before running," Fortinet Fortiguard Labs researcher Cara Lin  said  in a Tuesday analysis. "It als...

The  Kinsing  threat actors are actively exploiting a critical security flaw in vulnerable Apache ActiveMQ servers to infect Linux systems with cryptocurrency miners and rootkits. "Once Kinsing infects a system, it deploys a cryptocurrency mining script that exploits the host's resources to mine cryptocurrencies like Bitcoin, resulting in significant damage to the infrastructure and a negative impact on system performance," Trend Micro security researcher Peter Girnus  said . Kinsing  refers to a  Linux malware  with a history of targeting misconfigured containerized environments for cryptocurrency mining, often utilizing compromised server resources to generate illicit profits for the threat actors. The group is also known to quickly adapt its tactics to include newly disclosed flaws in web applications to breach target networks and deliver crypto miners. Earlier this month, Aqua  disclosed  the threat actor's attempts to exploit a Linux pri...

Cybersecurity researchers have demonstrated a new technique that exploits a critical security flaw in Apache ActiveMQ to achieve arbitrary code execution in memory. Tracked as  CVE-2023-46604  (CVSS score: 10.0), the vulnerability is a remote code execution bug that could permit a threat actor to run arbitrary shell commands. It was patched by Apache in ActiveMQ versions 5.15.16, 5.16.7, 5.17.6, or 5.18.3 released late last month. The vulnerability has since  come under   active exploitation  by ransomware outfits to deploy ransomware such as HelloKitty and a strain that shares similarities with TellYouThePass as well as a remote access trojan called SparkRAT. According to  new findings  from VulnCheck, threat actors weaponizing the flaw are  relying  on a public proof-of-concept ( PoC ) exploit originally disclosed on October 25, 2023. The attacks have been found to use  ClassPathXmlApplicationContext , a class that's part of the...
