According to a recent Financial Times article, the amount of crypto sent to addresses with known criminal associations shot to a record $14 billion in 2021, more than doubling from 2020. This is according to research from data company Chainalysis. Scams, ransomware and theft rose 79% in dollar terms last year. This is perhaps unsurprising when you look at our aggregator table below of the notable scams, hacks and thefts of 2021.
The key takeaways from last year’s hacks and scams can be distilled down to the following:

USD $139 million |
Boy X Highspeed (BXH), a decentralised cross-chain exchange, was hacked in October in a hack that drained $139 million of funds.

With the private key, the attacker was able to digitally sign a transaction transferring $139 million in tokens from BXH’s account on BSC to their own account. |
BXH’s CEO stated that an investigation was underway to identify the hacker. If the hacker is not found, BXH has said that it will devise a user repayment plan and is offering $1 million to teams able to help retrieve the funds. |

As reported above, it appears that the owner used a flash loan to make the fake purchase of the Punk, borrowing and repaying 124,000 ETH. The move was likely a marketing stunt. |
