Considering the botnet's enormous scale and the filename pandoraspear, we dubbed the cybercime syndicate Bigpanzi. Once installed, these devices transform into operational nodes within their illicit streaming media platform, catering to services like traffic proxying, DDoS attacks, OTT content provision, and pirate traffic. Differing from typical botnets spreading through 0/N day vulnerabilities, this group's modus operandi involves enticing users to install free or cheap audio-visual apps or firmware updates, embedding backdoor components. This syndicate primarily targets Android OS TVs and set-top boxes, as well as eCos OS set-top boxes. These tools further led us to 32 eCos platform firmwares embedding five domains, which shared the same IP for C2 resolutions as pcdn.Īs our investigation and source tracing deepened, a major cybercrime syndicate, active since 2015, gradually surfaced. For instance, specific strings in pcdn pointed us to two Windows platform DDoS tools linked to the group. Moreover, the implants unraveled further connections. These were hard-coded into a set of APKs used for deploying pandoraspear/pcdn-containing Android platform firmware upgrades. Notably, a discernible pattern in the Downloader URLs within these scripts led us to 22 such URLs. These scripts either directly provided additional implants for the syndicate, like pcdn, ptcrack, and p2p_peer, or indirectly expanded our insight. This led us to various download scripts, such as a.sh, pd.sh, and cpcdn.sh. We finished analyzing the sample fast and started monitoring the botnet's attack instructions. This greatly limits our ability to observe and track them. This strategy redirects certain domain names to specific IP addresses, bypassing the normal DNS resolution process used to find the IP addresses of Command and Control domains. They bombarded our domains with DDoS attacks to force them offline and manipulated the hosts files of the infected devices. Upon realizing that we had secured their domains, the group countered aggressively. At its peak, we noted approximately 170,000 daily active bots, predominantly in Brazil. We seized this opportunity to register these domains to gauge the botnet's scale. Our analysis revealed that it hardcoded nine C2 domain names, two of which had lapsed beyond their expiration protection period. This sample, named pandoraspear and employing a modified UPX shell, has an MD5 signature of 9a1a6d484297a4e5d6249253f216ed69.
