According to PANews, blockchain investigator ZachXBT has claimed that the North Korean hacker group Lazarus has laundered $200 million worth of stolen cryptocurrency into fiat currency over a four-year period. The group is known for its cyber-attacks and has been active in the cryptocurrency space for several years.

ZachXBT's allegations, if proven, would highlight the extent of Lazarus' activities in the digital currency market. The group's alleged actions could have significant implications for the security and integrity of the cryptocurrency market.

This is not the first time Lazarus has been linked to such activities. The group has been accused of several high-profile cyber-attacks in the past, including attacks on banks and other financial institutions. The laundering of stolen cryptocurrency into fiat currency would represent a significant escalation in the group's activities.

The claims made by ZachXBT are yet to be verified. If proven, they could have serious implications for the security of the cryptocurrency market and could lead to increased regulatory scrutiny. The allegations also highlight the potential risks associated with digital currencies, including the risk of theft and the potential for money laundering.
