Crypto crime rates are dropping despite a massive increase in attacks targeting the DeFi sector, reports security firm CipherTrace.
Crimes targeting the virtual currency sector decreased by more than half in 2020 according to blockchain security firm CipherTrace.
The firmās 2020 cryptocurrency crime and anti-money laundering report revealed that losses from cryptocurrency theft, hacks, and fraud fell 57% in 2020 to $1.9 billion, due mainly to improved security systems. The same figure in 2019 hit a record $4.5 billion.
CipherTrace said that āmassive exit scamsā such as the PlusToken Ponzi dominated crypto crime over the past two years, with that scam alone netting $2.9 billion. In 2020, a similar scheme by some of the same culprits called WoToken defrauded investors out of $1.1 billion, accounting for 58% of the yearās major crime volume.
The report found that fraud is the dominant cryptocurrency crime, followed by theft and ransomware. Dave Jevans, CipherTraceās chief executive officer, told Reuters:
āThefts from hacks against centralized exchanges continue to decrease as these financial institutions mature and adopt stronger security measures,ā
However, 2020 saw a surge in decentralized finance related crime, the majority of which were ārug pullsā. Thatās where a token is artificially hyped and inflated, with the creators and early investors pulling the plug after the pump leaving the latecomers out of pocket.
The report explained that some bad actors will liquidate the entire liquidity pool, leaving the remaining token holders with no liquidity and unable to trade, wiping out the remaining value of the token:
āHalf of all 2020 crypto hacks were of DeFi protocolsāa pattern that was virtually negligible in all prior yearsāand nearly 99% of major fraud volume in the second half of 2020 stemmed from DeFi protocols performing ārug pullsā and other exit scams in a pattern eerily reminiscent of the 2017 ICO craze.ā
Due to being mostly unregulated, DeFi protocols have many exemptions from traditional enforcement regimes that centralized exchanges, money service businesses and banks face, Jevans added.
The report stated that 2020ās largest theft, the $281 million hack of the centralized exchange KuCoin, also involved the DeFi sector as criminals attempted to launder the stolen funds through Uniswap, the worldās largest decentralized exchange.
