Summary:
The cybercrime syndicate ‘Bigpanzi’ has been infecting Android TV and eCos set-top boxes to create a large botnet used for illegal activities, including media streaming, DDoS attacks, and content provision. Their customized malware, pandoraspear and pcdn, poses serious cybersecurity threats. The scale of their operations, involving over 1.3 million distinct IPs, presents a significant challenge for cybersecurity analysts.
Based on the meeting notes, it is clear that a cybercrime syndicate named ‘Bigpanzi’ has been actively infecting Android TV and eCos set-top boxes worldwide since at least 2015. This syndicate has been able to net significant earnings by controlling a large-scale botnet with approximately 170,000 daily active bots, with a majority of these IPs located in Brazil. The infections are typically carried out via firmware updates or backdoored apps that users unwittingly install themselves. The cybercriminals then use these infected devices for various illicit purposes, including illegal media streaming platforms, traffic proxying networks, distributed denial of service (DDoS) swarms, and over-the-top (OTT) content provision.
The syndicate has customized malware tools named ‘pandoraspear’ and ‘pcdn’ to execute their operations, with pandoraspear acting as a backdoor trojan hijacking DNS settings and establishing command and control (C2) communication, while pcdn functions to build a peer-to-peer (P2P) Content Distribution Network (CDN) on infected devices and possesses DDoS capabilities to weaponize devices.
It is evident that Xlabs has conducted extensive research into the scale of operations of this cybercrime syndicate, noting that they observed over 1.3 million distinct IPs associated with the botnet since August, with a large number of nodes detected in Brazil. However, Xlabs indicates that due to the limitations of their visibility, the actual size of the botnet may be larger than currently known.
Furthermore, Xlabs has suggested a link between the syndicate and a suspicious YouTube channel controlled by a company, although no attribution details have been disclosed, possibly being reserved for applicable law enforcement authorities.
Overall, the meeting notes reveal the extensive and sophisticated operations of the ‘Bigpanzi’ cybercrime syndicate and the significant implications for cybersecurity and law enforcement efforts.
