Recent blockchain security monitoring has revealed renewed activity from an address linked to the 2019 Upbit exchange breach (starting with 0x93A0). Chain analytics show that over 1,400 ETH have been funneled into a privacy-focused protocol, signaling a significant shift in the long-dormant hacker’s strategy and drawing industry-wide attention.

Large-Scale Movements Trigger Red Flags

The transferred ETH, valued at approximately $36 million, marks the first major movement from this address in years. According to MistTrack, the attacker is using staggered transactions to evade detection—a tactic commonly seen in high-profile exchange heists and illicit fund laundering.

Privacy Tools Complicate Tracking Efforts

The destination protocol enhances transaction anonymity, making it difficult to trace the final recipients. While such tools serve legitimate privacy needs, their misuse in obscuring stolen funds remains a growing concern for regulators and security teams alike.

  • Transactions split across multiple blocks, ranging from 50–100 ETH each
  • Source wallet had been inactive for years before recent activation
  • Intermediate relays include cross-chain bridging services

Call for Stronger Exchange Safeguards

This resurgence highlights the persistent risks in digital asset custody. Experts recommend enhanced cold wallet protocols, real-time anomaly detection systems, and deeper integration with on-chain intelligence platforms to counter evolving threats in fund diversion tactics.
