According to @zachxbt, a prior KrebsOnSecurity investigation identified Ice Blockchain/Online.io CEO Alexandru Ionut Florea, also known as Zeus, as an administrator behind the Microleaves residential proxy network that researchers alleged was powered by malware/botnet activity (source: @zachxbt; KrebsOnSecurity). According to @zachxbt, he also linked Florea and Online.io (OIO) to the 2018 OIO ICO, which he characterized as a rug, raising sponsor-vetting concerns and headline risk for any entities associated with Ice Blockchain/Online.io from a trading due-diligence standpoint (source: @zachxbt).
