14 people have reportedly been arrested by police in Taiwan in connection with a $5.41 million crypto investment scam according to The Taipei Times.
Poly Network has taken the unusual step of embracing the apparent hacker, who stole $610 million in early August.
Japanese crypto exchange Liquid said that bitcoin, ether, XRP and TRX coins were stolen in the hack, and it was trying to track down the crypto.
"We cordially invite Mr. White Hat to be the Chief Security Advisor of Poly Network," the company said.
"We have determined that unauthorized access to some T-Mobile data occurred," a spokesperson said in a statement.
There is $268 million worth of ether that has yet to be returned to Poly Network as of Thursday afternoon.
The hacker appeared to be returning part of their loot to Poly Network after saying they would do so if the DeFi platform met certain conditions.
The South-Africa based lawyers told Bloomberg their mandate to assist the brothers has been terminated.
