Hackers known as Predatory Sparrow claim responsibility for rendering Nobitex exchange funds inaccessible

An Israel-linked hacking group has claimed responsibility for a $90m (£67m) heist on an Iranian cryptocurrency exchange.

The group known as Gonjeshke Darande, Farsi for Predatory Sparrow, said on Wednesday it had hacked the Nobitex exchange, a day after claiming it had destroyed data at Iran’s state-owned Bank Sepah.

Elliptic, a consultancy specialising in crypto-related crime, said it had so far identified more than $90m in cryptocurrency sent from Nobitex crypto wallets to hacker addresses.

The hackers appear to have in effect “burned” those funds, rendering them inaccessible by storing them in “vanity addresses” for which they do not have the cryptographic keys, Elliptic said.
