December 20 — On-chain researcher Specter reports that the address which lost 50 million USDT in a phishing attack yesterday left an on-chain message for the attacker, noting a formal case has been filed. With help from law enforcement, cybersecurity agencies and multiple blockchain protocols, authorities have gathered significant actionable intelligence on the attacker’s activities. The attacker’s controlled wallet address is now under 24/7 monitoring. The attacker has been asked to return 98% of the stolen funds to a designated address within 48 hours. If compliant, they may keep $1 million as a white hat bounty (to reward vulnerability discovery and disclosure). This offer depends on full, timely cooperation. Upon return of the funds, victims will consider the matter resolved and take no further action. If the attacker refuses, the case will be escalated via legal and international law enforcement channels to identify the attacker and pursue criminal and civil charges.
