You can download the “ lazaruswannacry” Yara rule here. Yes, Matt Suiche from Comae Technologies confirmed the same similarity based on Neel’s samples:Ĭan you share the YARA rule used to find this? Further research can be crucial to connecting the dots. In time, more evidence appeared and allowed us, and others, to link them together with high confidence. Looking back to the Bangladesh attack, in the early days, there were very few facts linking them to the Lazarus group. We believe it’s important that other researchers around the world investigate these similarities and attempt to discover more facts about the origin of Wannacry. We strongly believe the February 2017 sample was compiled by the same people, or by people with access to the same sourcecode as the May 2017 Wannacry encryptor used in the May 11th wave of attacks. They also removed an older extension: “.tar.bz2” and replaced it with just “.bz2” Yes, it shares the same the list file extension targets for encryption but, in the May 2017 versions, more extensions were added: Are we sure the early February variant is the precursor to the later attacks? One thing is for sure - Neel Mehta’s discovery is the most significant clue to date regarding the origins of Wannacry. His next US stakes victory would come in the 177,000 Hoosier Park Pacing Derby where he paced.

Sent to race in North America, Lazarus N won the 325,000 Dan Patch in his North American stakes debut. We believe this might hold the key to solve some of the mysteries around this attack. Lazarus N was a 15 time Group 1 winner, establishing 5 track records in New Zealand and another 3 records in Australia. What conclusions can we make?įor now, more research is required into older versions of Wannacry. We believe a theory a false flag although possible, is improbable. The February 2017 sample appears to be a very early variant of the Wannacry encryptor.

However, this code appears to have been removed from later versions. In theory anything is possible, considering the 2015 backdoor code might have been copied by the Wannacry sample from February 2017. During that research, which we also participated in, hundreds of samples were collected and show that Lazarus is operating a malware factory that produces new samples via multiple independent conveyors. The group has been very active since 2011 and was originally disclosed when Novetta published the results of its Operation Blockbuster research. The scale of the Lazarus operations is shocking. We believe Lazarus is not just “yet another APT actor”. See:Īmong other things, the Lazarus group was responsible for the Sony Wiper attack, the Bangladesh bank heist and the DarkSeoul operation.

We wrote about the Lazarus group extensively and presented together with our colleagues from BAE and SWIFT at the Kaspersky Security Analyst Summit (SAS 2017). I know about Wannacry, but what is Lazarus? So, what does it all mean? Here’s a few questions and answers to think about. The similarity can be observed in the screenshot below, taken between the two samples, with the shared code highlighted:

A Lazarus APT group sample from February 2015.

A WannaCry cryptor sample from February 2017 which looks like a very early variant.

The two samples Neel refers to in the post are: The cryptic message in fact refers to a similarity between two samples that have shared code. A few hours ago, Neel Mehta, a researcher at Google posted a mysterious message on Twitter with the #WannaCryptAttribution hashtag:
