What is GorillaBot?
Gorilla Botnet, also known as GorillaBot, is a botnet family that recently gained momentum and notoriety. It was first observed in 2023. However, industry researchers did not report on GorillaBot until recently, when it was observed in a high-volume attack. Between September 4-27th, GorillaBot conducted a series of high-density attacks, issuing over 300,000 attack commands. NSFocus reported on GorillaBot.
GorillaBot is an offshoot of Mirai and is capable of targeting a variety of architectures, including ARM, MIPS, x86_64, and x86. For DDoS, GorillaBot uses UDP flood, ACK BYPASS flood, VSE flood, SYN flood, and ACK flood. Using the connectionless UDP protocol facilitates high attack traffic in relation to the limited number of bots used.
During the high volume of attacks in September, GorillaBot targeted over 100 countries. Of the over 20,000 targets affected, China and the US had the most victims. Targeted entities included those in the education, government, telecommunications, financial, and gaming sectors. At least 40 targets were critical infrastructure entities.
NSFocus researchers noted that GorillaBot uses DDoS attack methods and encryption algorithms typically associated with KekSec. GorillaBot is sophisticated, using multiple techniques to maintain persistence and showing a high level of counter-detection awareness. PolySwarm analysts consider GorillaBot to be an emerging threat due to its sophistication and the recent demonstration of its capability for high-volume attacks.
