Vulnerability in transaction signature verification algorithm

Data Sources:

The well-known public chain NULS was attacked by hackers, and 2 million tokens in the team account were stolen. The SlowMist security team found that the cause of the attack was a vulnerability in the NULS transaction signature verification algorithm. Hackers used carefully constructed transactions to bypass signature verification and transferred the tokens of the team’s account. Then some tokens were thrown to the market. At present, major exchanges have suspended the deposit and withdrawal of NULS. After the attack, the government urgently investigated the problem, carried out problem fixes and code testing, and then released a new version of the program, and scheduled a hard fork at a height of 878000 to freeze other tokens that did not enter the market.
