Wu said that SlowMist Yuxian tweeted that after reviewing the two thefts of FixedFloat, it was said that the root cause of the problem came from the hosting service provider Time4VPS, which is cheap but unreliable, especially: the attacker obtained all functional permissions of the host, including global access to all available servers, which made the previous measures completely ineffective. The cryptocurrency industry should not choose such a small service provider. FixedFloat was previously attacked and lost more than $26 million worth of Bitcoin and ETH.
