Summary
Bitcoin blockchain transactions are being leveraged by a piece of malware from a known crypto mining botnet campaign to hide its backup command-and-control IP address and defeat takedown attempts. Remote code execution vulnerabilities in numerous Internet facing applications are being exploited to gain initial access. Shell scripts used during the infections scan for additional servers to infect, disable security tools, establish persistence, and download and start crypto-miners.
Our Threat Research team gathers and analyzes information from multiple open and closed sources before disseminating intelligence reports. This campaign was researched by Akamai Technologies and shared publicly.
