GorillaBot Overview: Key Threat Information<\/h2>\n

GorillaBot is a recently identified botnet<\/a>, classified as a variant of the Mirai botnet, which gained notoriety for its role in large-scale Distributed Denial of Service (DDoS) attacks. Mirai, first discovered in 2016, primarily targets internet-connected devices like IoT cameras and routers, exploiting weak or default passwords to build its botnet.<\/p>\n\n\n\n\n\n\n\n\n\n

The release of Mirai’s source code<\/a> has led to numerous variants, with GorillaBot emerging as a significant threat in 2023, launching over 300,000 attacks across more than 100 countries<\/strong> between September 4 and September 27, 2023. These attacks targeted critical sectors including telecommunications, financial institutions, and education.<\/p>\n

This malware appears to reuse Mirai’s core logic for DDoS attacks, such as command parsing and communication with control servers. However, it enhances these with custom encryption methods and includes anti-debugging features to evade detection. This makes it a more sophisticated threat compared to the original Mirai.<\/p>\n

Technical Analysis of GorillaBot<\/h2>\n

Security researchers at ANY.RUN have published a detailed analysis<\/a> of this threat. Our focus here is on the key technical aspects that differentiate GorillaBot from the original Mirai while making it more dangerous and difficult to detect.<\/p>\n

Code Reuse and Architecture Support<\/h3>\n

GorillaBot inherits much of its functionality from Mirai, focusing on DDoS attacks<\/a>. Analysis of its binary reveals that it supports multiple system architectures:<\/p>\n
