According to Golden Finance, Slow Fog founder Cosine posted on social media that there is no problem with the Safe contract, and the problem is that the non-contract part is tampered with forged in the front end to achieve the 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 multiple signs), the Radiant Capital incident ($50 million stolen, Safe multiple signs), and DMM (3.05 stolen, $100 million, Gonco signed more). This attack method is engineered and mature. Other companies also need to pay more attention. More signings may not only have such attack points in Safe.
