Tool: Contopee

Names	Contopee WHITEOUT
Category	Malware
Type	Backdoor
Description	(SecurityWeek) Aside from commonalities in the tools used to spread WannaCry, there are also a number of links between WannaCry itself and Lazarus. The ransomware shares some code with Backdoor.Contopee, malware that has previously been linked to Lazarus. One variant of Contopee uses a custom SSL implementation, with an identical cipher suite, which is also used by WannaCry. The cipher suite in both samples has the same set of 75 different ciphers to choose from (as opposed to OpenSSL where there are over 300).
