Attack details and reimbursement plan
As reported by Cointelegraph, citing Bitquery, the attack drains $953,000 in 94 seconds from 48 cryptocurrency wallets belonging to nine traders who had used the Bloom bot. The blockchain analytics company says each wallet drain is a Solana transfer signed with the affected wallet's private key.Bloom says it will reimburse all affected traders in full. In a later Monday statement, the company attributes the attack to a remote code execution vulnerability in a third-party module and says no private keys have been accessed or compromised.
Telegram bot security risks intensify
Trading bots such as Bloom hold users' private keys so they can execute trades on users' behalf, a structure that can leave lingering security risks even after traders stop using the service. Bitquery says five of the wallets drained in the Bloom incident have been inactive on the bot since the first half of 2025.The incident adds to a series of losses involving Telegram trading bots. In September 2024, Banana Gun reports that 11 users lose about $3 million, while in October 2023 users of Maestro and Unibot lose a combined $1.1 million in exploits targeting their router contracts.
