According to ChainCatcher, according to a report by blockchain intelligence company TRM, the amount of cryptocurrency stolen through hackers and network vulnerabilities in the first half of this year more than doubled to $1.38 billion. Among them, five large attacks accounted for 70% of the stolen cryptocurrency. Despite this, the amount of theft in the first half of this year is still lower than the nearly $2 billion in the first half of 2022, which was also a record year for cryptocurrency theft.

TRM said that hackers mainly steal cryptocurrencies by obtaining encrypted strings such as private keys and seed codes. The largest attack this year occurred on the Japanese exchange DMM Bitcoin, with more than $300 million worth of bitcoins stolen and more than 4,500 tokens. At present, the cause of the attack has not yet been determined.
