It's surprising to see this news that Akropolis which got audited was also attacked. I think these hackers are targeting DEFI platforms with lending feature especially. I remember buying 2k$ worth of BZRX before their platform official launch, but price went south after their platform hack. I think the audit companies do need to upgrade, in order to spot loopholes which can be taken advantage by hackers. I still need to further confirm the hack case with Akropolis anyway, information here is not enough.
