Comae analyzed WannaCry variants that appeared after the initial outbreak, including one live sample seen in the wild and one no-kill-switch sample that Kaspersky recovered from VirusTotal. The live variant used the kill-switch domain ifferfsodp9ifjaposdfjhgosurijfaewrwergwea[.]com, which the author registered and sinkholed to stop another infection wave. The source lists hashes for the original and new samples and notes that the no-kill-switch build still spread through ETERNALBLUE and DOUBLEPULSAR but did not encrypt files because its ransomware archive was corrupted. A later update flags reported Lazarus attribution links, but the technical evidence in this excerpt centers on variant behavior, kill switches, and sample comparison.
