PANews reported on November 29 that, according to Cointelegraph, Ronghui Gu, co-founder of blockchain security company CertiK, said that as of November 28, hacking attacks in 2023 alone have caused $1.5 billion in losses in the crypto field. Ronghui Gu believes that these hacks and vulnerabilities have had a huge impact on cryptocurrency adoption and undermine public trust in the security and stability of digital assets, and that the ongoing security incidents caused by SIM-swap and multi-signature failures are "unforgivable" and that companies should accept crypto-native multi-factor authentication and conduct regular security audits.
