Data: Cryptocurrency hacks and scams cost $364 million in April

The cryptocurrency sector lost about $364 million in April to hacking, fraud, and exploits, the vast majority of which ($337 million) was related to phishing attacks, according to new estimates from CertiK. Most of the ill-gotten gains stemmed from a single incident in which attackers used complex social engineering to steal 3,520 bitcoins from wallets. In addition, decentralized exchange KiloEX lost $7.50 million due to a "price oracle vulnerability", Loopscale was stolen 5.80 million, and the Ethereum scaling protocol ZKsync airdrop contract was withdrawn for nearly $5.30 million, although all three platforms have recovered funds from white hat hackers. Losses in April increased significantly from March ($28.80 million), but are still small compared to the $1.50 billion lost by North Korean hacking group LazarusGroup in February's attack on Bybit. In light of the frequent phishing attacks, CertiK reminds crypto companies and investors to verify the authenticity of URLs and smart contracts before transferring money, and also recommends using cold wallets for storage and not sharing position information on social media.
