Major Attacks of June: Nobitex Hack and Losses of Other Projects
The most notable event was the hack of the Iranian cryptocurrency exchange Nobitex, resulting in the theft of assets worth $82 million. According to experts, the hacker group Gonjeshke Darande, also known as Predatory Sparrow, is responsible for the incident, claiming responsibility for the attack. Following the hack, the Central Bank of Iran restricted the operating hours of cryptocurrency exchanges, allowing transactions only from 10:00 AM to 8:00 PM. On June 30, the Nobitex platform announced that it had granted verified users access to their wallets; however, trading and deposit functions remain unavailable at this time.
“Representatives of Nobitex emphasized that they continue to work on restoring withdrawals and deposits, as well as trading operations. According to the developers, these functions will only be available for authenticated users.”
Among other significant losses, the incident involving the ResupplyFi project stands out, with losses amounting to $9.6 million. The protocol team clarified that the exploit affected only the wstUSR market; a vulnerability in the smart contract has already been identified, and the developers promised to provide a detailed report soon.
Additionally, the ALEXLabBTC ($8.4 million) and ForceBridge ($3.8 million) platforms also suffered financial losses. There are also reports of a theft of $3.2 million from one of the users in the Solana network. In total, around 15 significant attacks on cryptocurrency projects occurred throughout June.
Security in the Crypto Sector Remains Threatened
Despite the decrease in the volume of losses, experts emphasize that the security situation in the cryptocurrency sector remains complex. Infrastructure-level hacks, as well as attacks on individual users, continue to pose a serious threat to the entire industry. It was previously reported that in the first half of 2025, the crypto industry lost a record $2.1 billion due to the activities of hackers.
