Zilliqa Accounts Exposed by Ledger Bug

A recent bug in the Ledger app exposed at least 6,772 Zilliqa accounts, allowing attackers to steal 683.13 million ZIL across 66 transactions.

The disclosure turned an earlier unquantified security flaw into a measured loss and exposure record.

According to the post-mortem, the bug allowed attackers to reconstruct private keys from public blockchain data in seconds on ordinary hardware, using four or more biased signatures produced by the Ledger app.
