Numbered Panda has a long list of high-profile victims and is known by a number of names including: DYNCALC, IXESHE, JOY RAT, APT-12, etc. Numbered Panda has targeted a variety of victims including but not limited to media outlets, high-tech companies, and multiple governments. Numbered Panda has targeted organizations in time-sensitive operations such as the Fukushima Reactor Incident of 2011, likely filling intelligence gaps in the ground cleanup/mitigation operations. One of the most interesting techniques that Numbered Panda likes to use is to dynamically calculate the Command and Control (C2) port by resolving a DNS. The malware will typically use two DNS names for communication: one is used for command and control; the other is used with an algorithm to calculate the port to communicate to. There are several variations of the algorithm used to calculate the C2 port, but one of the most common is to multiply the first two octets of the IP address and add the third octet to that value. Numbered Panda will frequently use blogs or WordPress in the c2 infrastructure, which helps to make the network traffic look more legitimate. CrowdStrike has observed Numbered Panda targeting high-tech, defense contractors, media organizations, and western governments. Disclosure of this information went through the same IGL process as discussed in the Whois Anchor Panda blog post
