A relatively unknown cryptocurrency exchange by the name of BitGrail has informed its users of a coordinated cyber attack targeting Nano (XRB) tokens. However, the incident does not appear to be holding up to scrutiny after the founder of the exchange made an odd request to the developers of Nano shortly after discovering the alleged theft.
The Italian exchange issued a notice to its clients last week informing them that 17 million XRB tokens were compromised in a cyber attack. The XRB token, formerly known known as Raiblocks, is valued at $9.80 at the time of writing for a total market cap of $1.3 billion. That puts the total monetary loss of the supposed heist at nearly $167 million.
Parts of the notice have been translated into English from the original Italian by Tech Crunch, a media company dedicated to startups and technology news. According to the agency, BitGrail has stated the following:
“… Internal checks revealed unauthorized transactions which led to a 17 million Nano shortfall, an amount forming part of the wallet managed by BitGrail… Today a charge about those fraudulent activities has been submitted to the competent authorities and now is under police investigation.”
The notice indicated that all transactions have been put on hold until authorities complete their investigation.
Very little is known about BitGrail, as it is not listed among the 183 exchanges whose volume is ranked by CoinMarketCap.
Unlike other crypto heists, the circumstances surrounding the alleged BitGrail attack have been met with widespread suspicion. As David Z. Morris of Fortune rightly notes, this isn’t the first time BitGrail has suspended Nano withdrawals. The same thing happened in early January when the exchange halted not only Nano, but Lisk and CryptoForecast transactions as well.
The suspension was followed by an announcement that the exchange was taking measured steps to verify users and enforce anti-money laundering requirements. It was around this time that users became suspicious that BitGrail was going to cut and run with their tokens.
BitGrail founder Francesco Firano made an unusual request to the developers of Nano following the alleged attack: he asked them to fork their record, a move that would essentially restore the stolen funds.
Nano officially rejected the request on Friday, the day after Firano supposedly discovered the stolen coins. In a post that appeared on the Nano Medium page, the team said:
“We now have sufficient reason to believe that Firano has been misleading the Nano Core Team and the community regarding the solvency of the BitGrail exchange for a significant period of time.”
Last month, hackers made off with more than $400 million worth of NEM tokens stolen from Coincheck, a Japan-based cryptocurrency exchange. The coins have yet to be recovered and the perpetrators remain at large. In 2014, a cyber heist brought down Mt Gox, which was the world’s largest exchange.
