According to the report, approximately $309 million of losses have been identified by law enforcement as being associated with the Lazarus Group, a cybercriminal organization with ties to the Democratic People’s Republic of Korea, also known as North Korea. These losses include those from the Atomic Wallet hack ($100 million), CoinEx ($70 million), Alphapo ($60 million), Stake, CoinsPaid and others.

The vast majority of funds lost were from hacks rather than fraud. Only $103 million was lost from clearly identifiable fraud schemes, such as rug pulls, whereas over $1.6 billion was lost from hacks and exploits. The majority of losses — $1.3 billion — came from protocols claiming to be decentralized. Only $409 million was lost from centralized finance (CeFi) crypto protocols, the report stated.

The $1.8 billion in losses appears to represent a more than 52% decline from the previous year, when blockchain security platform Chainalysis reported  over $3.8 billion in stolen funds.
