The NULS blockchain platform has revealed in a security update that hackers have stolen 2,000,000 NULS tokens worth $480,000 from one of the accounts on the platform. A total of 548,354 stolen NULS tokens have already been traded and hence, could not be traced. The stolen NULS tokens represent 2% of the 73 million NULS tokens in circulation.
NULS also said that it had fixed a security vulnerability in NULS 2.2 version that allowed the hackers to hack the platform. It urged node operators to upgrade their systems.
NULS informed users that in light of the hack attack, it had decided to carry out a hard fork, after which the remaining 1451645 NULS tokens which have not been traded by the hackers, will be destroyed by putting them in a deep freeze. Thus, hackers will not be able to trade the remaining NULS tokens and cause loss to NULS users.
Additionally, NULS is also working with cryptocurrency exchanges to prevent further trading of stolen NULS tokens.
In 2016, Ethereum had opted for a hard fork after a hack attack and created Ethereum Classic. Hackers still managed to steal $50 million from the network after the hard fork.
