Mirai Variant Nexcorium Exploits CVE-2024-3721 to Hijack TBK DVRs for DDoS Botnet

The Hacker News

Researchers from Fortinet FortiGuard Labs and Palo Alto Networks Unit 42 have identified that attackers are exploiting a command injection vulnerability, CVE-2024-3721, in TBK DVRs and outdated TP-Link Wi-Fi routers. This medium-severity flaw, which has a CVSS score of 6.3, allows malicious actors to hijack these devices to create a botnet for DDoS attacks. The compromised TBK DVRs and EoL TP-Link routers are particularly concerning as they can be easily targeted due to their lack of ongoing support and security updates. This situation poses a significant risk to users, as their devices can be turned into tools for larger-scale cyberattacks without their knowledge. Users of these devices should take immediate action to secure their systems against potential exploitation.
