A study by SlowMist says that cybercriminals have managed to steal about $30 billion in digital currencies since 2012.
In total, there were just over 1,100 successful attacks during this time, as a result of which the attackers managed to steal funds. Most often, they found vulnerabilities in smart contracts to gain access to the information and crypto wallets of victims.
The total damage caused by hackers and fraudsters is estimated at about 2.5% of the crypto market capitalization.
