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. We encourage you to do your own research before investing.A few hours ago, Neel Mehta, a researcher at Google posted a mysterious message on Twitter with the #WannaCryptAttribution hashtag:

The stolen funds as the laundering progresses, and will update its tools to reflect the movement of these assets.ĭISCLAIMER: The Information on this website is provided as general market commentary and does not constitute investment advice. The relatively short periods during which the stolen funds stop being moved out of Tornado cash are consistent with APAC nighttime hours.We have observed very similar programmatic laundering of funds stolen from the Ronin Bridge, which has been attributed to Lazarus, as well as a number of other attacks linked to the group.

The regularity of the deposits into Tornado over extended periods of time suggests that an automated process is being used.Although Harmony is based in the US, many of the core team have links to the APAC region. Lazarus Group tends to focus on APAC-based targets, perhaps for language reasons.Such techniques have frequently been used by the Lazarus Group. The theft was perpetrated by compromising the cryptographic keys of a multi-signature wallet – likely through a social engineering attack on Harmony team members.

For example, the group is believed to be behind the $540 million hack of Ronin Bridge.

The Lazarus Group has perpetrated several large cryptocurrency thefts totaling over $2 billion, and has recently turned its attention to DeFi services such as cross-chain bridges.

Wu Blockchain June 30, 2022Īccording to the analysis of Elliptic, it is consistent with the activities of Lazarus Group – a cybercrime group with close links to North Korea. Users of Elliptic’s solutions can now screen wallets and transactions for links to the stolen funds – even those that have passed through Tornado.Įlliptic: Suspected North Korean hackers known as the Lazarus Group are believed to be behind the recent $100 million heist on Harmony. However, Elliptic has used its Tornado demixing capability to trace all of the stolen funds through Tornado and onwards to other wallets. Mixers such as Tornado Cash are used to hide the transaction trail. The Horizon Bridge hacker has so far sent 41% of the $100 million in stolen cryptoassets into the Tornado Cash mixer.įollowing the trail after the Horizon hack. This is a common laundering technique used to avoid seizure of stolen assets. The thief immediately used Uniswap – a decentralized exchange (DEX) – to convert much of these assets into a total of 85,837 ETH. The stolen cryptoassets included Ether (ETH), Tether (USDT), Wrapped Bitcoin (WBTC) and BNB. On the morning of June 24th, over $100 million in cryptoassets was stolen from Horizon Bridge – a service that allows assets to be transferred between the Harmony blockchain and other blockchains. Elliptic appears to be a North Korean hack similar to the Ronin hack. The attacker’s wallet also contained 49,794 ETH. Harmony attackers transferred over 18,000 ETH to three addresses, most of which was subsequently transferred to Tornado Cash in batches of 100 ETH.
