SiloFinance Hacker Funnels 225 ETH to TornadoCash Amid Rising DeFi Security Concerns

Stock market information for Ethereum (ETH)

• Ethereum is a crypto in the CRYPTO market.
• The price is 2444.83 USD currently with a change of -42.08 USD (-0.02%) from the previous close.
• The intraday high is 2498.49 USD and the intraday low is 2402.62 USD.

🔐 What Happened

• Reemergence of Voltage Finance hacker
  Over half a year after the March 2022 exploit, the hacker resurfaced on May 6, moving 100 ETH (around $182,000–$183,000) from a long-dormant address linked to the original attack – flagged by CertiK .
• Funds funneled through Tornado Cash
  The ETH was sent into Tornado Cash, an Ethereum mixer designed to anonymize transactions—raising significant hurdles for tracing or recovering the stolen funds .

🤔 Why It Matters

1. Persistent DeFi vulnerabilities
   This move underlines that DeFi exploits aren’t one-off incidents—attackers may reemerge even years later as they strategize fund laundering .
2. Mixer-enabled money laundering
   Tornado Cash continues to play a crucial role in laundering stolen crypto. Once ETH enters it, recovery becomes extremely difficult .
3. Rising regulatory and audit pressure
   In Q1 2025 alone, crypto hacks hit $1.74 billion—already surpassing 2024’s total—making proactive audits and security measures more critical than ever .

🛡 Broader Takeaways for DeFi Security

• Audit, patch & verify continuously: Smart contracts must undergo repeated, rigorous testing to stay ahead of evolving attack methods.
• On-chain monitoring is vital: Security firms like CertiK play an essential role in detecting fund movements before they vanish into mixers.
• Searching for stolen funds becomes harder & costlier once assets enter anonymity tools like Tornado Cash.
• Privacy tools vs. criminal misuse: Tornado Cash’s dual-use nature keeps it at the center of ongoing debates about the balance between privacy and illicit use .

✅ Final Thoughts

The Voltage Finance hacker’s reappearance is a stark reminder: DeFi security isn’t a “fix once, forget forever” scenario. As soon as stolen funds are migrated into mixers, recovery becomes extremely unlikely. It underscores urgent needs for:

• Preemptive contract hardening,
• Real-time on-chain surveillance,
• And cross-industry collaboration between protocols, auditors, and regulators.
