This week brought us another series of DeFi hacks and scams resulting in the theft of more than $2.2M worth of tokens. Exchange hacks continue the trend of attackers targeting PII data, U.S. government knocked out another major malware actor, cryptomining malware is on the rise. This week also features a must-read CipherTrace report on cryptocurrency crime and a number of research articles on DeFi security.

On a more positive note, checkout my latest project called OpenBlockSec which aims to create a series of curated lists on security of smart contracts, blockchains, exchanges, and other related topics. The first list in the series documents all known blocksec CTF competitions and writeups. On this note, Paradigm CTF kicks off this Friday, which should be a fantastic opportunity to learn!
