Cryptocurrency / Security Threats
Recent findings by cybersecurity experts reveal a new campaign that targets a known vulnerability in the Apache HTTP Server to deploy a cryptocurrency miner named Linuxsys. This vulnerability, identified as CVE-2021-41773, carries a high severity rating (CVSS score: 7.5) and involves a path traversal issue in Apache HTTP Server version 2.4.49, which allows for remote code execution. According to Jacob Baines from VulnCheck, “Attackers exploit compromised legitimate websites to disseminate malware, facilitating hidden delivery and evasion of detection.” The infection process, traced back to an Indonesian IP address (103.193.177[.]152), aims to transfer a subsequent payload from “repositorylinux[.]org” using tools like curl or wget. This payload, a shell script, is tasked with downloading the Linuxsys cryptocurrency miner from five separate legitimate sites, indicating that the threat actors…
