RetoSwap Attacked Due to Haveno Protocol Vulnerability; Minimum Client Version Upgraded

RetoSwap, a Monero ecosystem P2P trading platform, announced that its Haveno trading protocol has been exploited by attackers. The team has urgently suspended trading by raising the minimum required client version to 2.0.0 and blocking the attackers’ Onion addresses. RetoSwap emphasized that its own infrastructure was not compromised; this incident stems from a vulnerability in the Haveno protocol. In May this year, RetoSwap disclosed a prior attack in which attackers exploited a protocol vulnerability to steal approximately 7,000 XMR—valued at roughly $2.7 million at the time.
