Woofun AI reports that Cardano's ADA token plummeted to multi-year lows after SecondFi, the network's largest wallet provider, suffered a significant security breach. Attackers exploited a vulnerability in wallet generation software to execute four separate thefts over a 72-hour window beginning June 22. The assault compromised 374 wallets and resulted in the loss of approximately 16 million ADA, valued at roughly $2.4 million at the time of the incident.

Developers confirmed the root cause resided strictly within SecondFi's proprietary software, leaving the underlying Cardano blockchain infrastructure completely unaffected. Although initial estimates suggested higher potential damage, funds moved into emergency custody remained secure throughout the crisis. The development team swiftly patched the software flaw for unaffected wallets and launched independent security audits to prevent recurrence.

To address the financial impact on victims, the team established a restoration fund while simultaneously evaluating legal action against the perpetrators.

Woofun AI data shows the market reaction was immediate, with ADA prices sliding to $0.139 on June 24 before stabilizing near $0.148. This valuation places the asset more than 95% below its all-time high, reflecting severe investor sentiment following the disclosure.

Technical analysis reveals a conflicting picture as a TD Sequential buy signal has emerged amidst the downturn. Analysts caution that this signal may represent a bull trap, noting that substantial resistance is expected between $0.160 and $0.176. Support levels are currently identified near $0.136 and $0.127, defining the immediate trading range.

The incident underscores the critical distinction between protocol security and third-party application vulnerabilities in the broader ecosystem. While the core network integrity holds, the reliance on external wallet providers introduces distinct systemic risks for asset holders. This marks a pivotal test of community resilience and recovery mechanisms following a major infrastructure failure.
