Blockchain platform Nuls has lost almost $480,000 worth of NULS tokens due to a hack, according to a security update tweeted on Dec. 22.
In its tweet, Nuls said it had detected that 2 million tokens had been transferred, of which 548,354 tokens — worth roughly $131, 600 — had entered the trading market and were now untraceable.
Mandatory hard fork upgrade to be released ASAP
In response to the theft, Nuls has decided to hard fork the blockchain at block height 87,800:
“After the hard fork, the remaining 1451645.65303905 NULS that has not entered the trading market will be destroyed in a permanent freeze to prevent continued flow into the market.”
The action should help to prevent losses to community members, the team claims. The hard fork will be released as soon as possible, with the team notifying node owners that an upgrade is mandatory and should be complied with ASAP.
Nuls revealed that hackers exploited a security vulnerability in the Nuls 2.2. version, which it says has now been fixed. It also notes that all relevant cryptocurrency exchanges have been contacted and are actively cooperating with the Nuls team.
Post-hack, Nuls token sees only mild losses
The stolen tokens represent only 2% of the circulating supply of over 73 million. The hack has seemed to have little effect on NUL’s price movement. At press time, NULS has lost 1% on the day and is trading at $0.238.
