CoinBene Hack
USD LOSS UNCONFIRMED
—
What happened
CoinBene's March 2019 wallet movements prompted suspicions of a hack. Reporting on Elementus's analysis described roughly $105 million moving from its hot wallet on March 25, followed by transfers to other exchanges. CoinBene denied a hack and attributed its downtime to maintenance.
The transferred value should not be treated as proven net loss.
Technical Root Cause
The cause of the suspicious transfers remains unconfirmed.
