Symantec investigation into WannaCry / Lazarus link
Following last week’s global WannaCry ransomware outbreak, Symantec has monitored and conducted a thorough investigation into the tools and infrastructure used in the WannaCry ransomware attacks, finding similarities and markers in the ransomware code that indicate a connection to the Lazarus group.
The Lazarus group was responsible for the destructive attacks on Sony Pictures and the theft of US$81 million from the Bangladesh Central Bank.
The first evidence Symantec has seen of WannaCry being used was February 10, when a single organisation was compromised. Within two minutes of the initial infection, more than 100 computers in the organisation were infected. A second iteration of the ransomware began on March 27, before going global on May 12.
