Title: TP-Link Router Botnet
Feedly Summary: There is a new botnet that is infecting TP-Link routers:
The botnet can lead to command injection which then makes remote code execution (RCE) possible so that the malware can spread itself across the internet automatically. This high severity security flaw (tracked as CVE-2023-1389) has also been used to spread other malware families as far back as April 2023 when it was used in the Mirai botnet malware attacks. The flaw also linked to the Condi and AndroxGh0st malware attacks.
