In view of the current new situation in blockchain security, 『Beosin』 concludes:
In general, the amount involved in various blockchain security incidents continued to decline in May 2023. the total amount of losses from various attacks reached $19.69 million in May, a decline of about 79% from April.
The amount involved in Rug Pulls exceeded that in attacks this month, and new ways of stealing coins such as using shared rechargeables to steal private keys also emerged. Hackers and scammers are gradually shifting the target of their attacks from various project parties to ordinary users. It is recommended that users must raise their anti-fraud awareness, research on projects background, and learn multiple methods to safeguard their assets. In addition, more than half of the projects attacked this month are unaudited, so it is recommended that you should always find a professional auditing company to conduct an audit before the project goes live.
