FortiGuard Labs is aware of a report that source code of BotenaGo malware was recently made available on GitHub. BotenaGo is a malware written in Golang and is reportedly capable of exploiting more than 30 vulnerabilities in various IoT devices such as routers, modems, and NAS devices, and varies the delivered payload depending on the device it successfully exploited.Why is this Significant?This is significant because the source code of BotenaGo malware is available on a publicly available repository and with the report that BotenaGo is capable of exploiting more than 30 vulnerabilities, an uptick of its activities is expected.What is BotenaGo Malware?BotenaGo is an IoT (Internet fo Things) malware written in Golang and may become a new arsenal used by Mirai attackers.The malware is reportedly capable of exploiting more than 30 vulnerabilities in various IoT devices (a list of those vulnerabilities is contained in the Alien Labs blog linked in the Appendix). After the targeted device is successfully exploited, the malware executes remote shell commands that download a payload that varies depending on the device it successfully compromised. BotenaGo also sets up a backdoor on the compromised machine and awaits remote commands from the attacker on ports 19412 and 31412. It can also set a listener to system IO (terminal) user input and get remote commands through it.What Vulnerabilities are Exploited by BotenaGo?Some of the known vulnerabilities exploited by BotenaGo are below:CVE-2013-3307: Linksys X3000 1.0.03 build 001CVE-2013-5223: D-Link DSL-2760U Gateway (Rev.
