According to online reports, Slowfog founder Yu Xin posted on social media saying that there is no problem with the Safe contract. The problem lies in the non-contract part. The front end has been tampered with and forged to achieve a deceptive effect. This is not an isolated case. North Korean hackers have successfully used this method several times last year, such as the WazirX incident ($230 million stolen, Safe oversigned), the Radiant Capital incident ($50 million stolen, Safe oversigned), and DMM ($305 million stolen, Gonco oversigned). This attack method is engineered and mature. Other homes also need to pay more attention. Safe may not only have such attack points.
