Odaily News According to MistTrack monitoring, the notorious wallet stealing group Inferno Drainer attempted to transfer the 174.1261 WETH (about $533,000) it stole through the privacy protocol Railgun. However, the behavior was blocked by Railgun and the relevant addresses were blacklisted, forcing them to send the tokens back to Inferno's original wallet address. Railgun contributor Alan Scott Jr said that Inferno maliciously attempted to use the Ethereum-based privacy protocol, but was rejected by Railgun's automated private proof of innocence (Private POI) system. Scott said: "Once the Private POI system is activated, these tokens can only be returned to the attacker's address." (Cointelegraph)
