Horizon Bridge hack attributed to Lazarus group

North Korean state-sponsored hacking operation Lazarus has been suspected to be behind the hack of Harmony's Horizon Bridge, which led to the theft of $100 million worth of cryptocurrency assets, according to SecurityWeek. Forty-one percent of the stolen funds have been transferred using the Tornado Cash mixer, which has been leveraged for cryptocurrency transaction concealment, a report from Elliptic revealed. The report attributed the theft to Lazarus hackers based on the malicious activity's nature and subsequent money-laundering procedure. "The regularity of the deposits into Tornado over extended periods of time suggests that an automated process is being used. 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," said Elliptic. The findings come after the U.S. government had linked the $600 million Ronin Validator cryptocurrency heist to Lazarus.
