INCIDENTMalicious-server transaction replacement and fee-bump loss
monitoring · high · since 2026-10-11
Electrum's October 24 advisory reports exploitation of versions before 4.8.3: a malicious server can replace a just-broadcast transaction in wallet history with an invalid transaction paying an attacker. Manually fee-bumping that transaction can sign the attacker payment. The developers report two user reports, including one loss. Version 4.8.3 includes signature checks for wallet-owned inputs; the patch is not evidence that lost funds were recovered. Electrum developer security advisory GHSA-6jp4-8v48-cc5v

Where is it available?

Is the operator based in a Five Eyes country?
