Kaspersky researchers may have found a potential connection between the SolarWinds hack to a previously known malware strain. Researchers say they found a number of shared features between the Sunburst and Kazuar malware. Both malware families were developed by the same threat group, the researchers say. The code similarities include the use of a sleeping algorithm to stay dormant for a random period between connections to a C2 server, the extensive usage of the FNV-1a hash to obfuscate the malicious code.
