Increased Threat Landscape
The alarming update follows revelations from cybersecurity firm CloudSEK regarding the AndroxGh0st malware. Threat actors are reportedly utilizing a range of security vulnerabilities, including CVE-2014-2120, to distribute this malware. Notably, this malicious activity is further amplified by the integration of the Mozi botnet, which has been known to expand its reach through exploiting various vulnerabilities.
CISA Response
In response to the growing concern, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has officially added CVE-2014-2120 to its Known Exploited Vulnerabilities (KEV) catalog. This action mandates that Federal Civilian Executive Branch (FCEB) agencies remediate the flaw by December 3, 2024, emphasizing the importance of addressing this security issue promptly.
