Coinsbuy offers $100K reward after Sunday security breach

Coinsbuy said it covered all affected client funds after unauthorized withdrawals, while an onchain investigator estimated more than $7.9 million was stolen.

Wallets linked to crypto payments platform Coinsbuy were reportedly drained of more than $7.9 million across Ethereum and TRON on Sunday.

According to a Telegram post from blockchain investigator SpecterAnalyst, the attacker began moving the stolen funds into Monero through exchanges, while ChangeNOW helped freeze a six-figure portion of the assets.

Coinsbuy temporarily paused deposits and withdrawals following the incident before restoring both services, according to SpecterAnalyst. The investigator identified three addresses linked to the stolen funds, including two Ethereum addresses and one TRON address.
