The cryptocurrency world is reeling from another high-profile hack, with reports surfacing that a user lost approximately $3.2 million in digital assets on May 16, 2025, in an attack attributed to the notorious Lazarus Group, a North Korean state-sponsored hacking syndicate. This incident, first highlighted by blockchain investigator ZachXBT, underscores the persistent threat posed by sophisticated cybercriminals targeting the crypto space. In this blog post, we’ll explore the details of the attack, the methods used, and what it means for the broader Web3 ecosystem.
What Happened?
According to posts on X, a user on the Solana blockchain had multiple wallets drained of $3.2 million worth of assets in a single attack on May 16, 2025. The stolen funds were quickly market-sold and bridged from Solana to Ethereum, a hallmark of the Lazarus Group’s tactics. By June 25, 2025, approximately 400 ETH (valued at roughly $1 million at the time) was deposited into Tornado Cash, a crypto-mixing service used to obscure the origin of stolen funds. This rapid movement of assets across blockchains and into mixers is consistent with the group’s playbook for laundering proceeds.
The attack was first reported by blockchain analyst ZachXBT on X, who noted that the victim’s wallets included multisig, externally owned accounts (EOAs), and exchange wallets, indicating a sophisticated breach likely involving malware or phishing. The funds were liquidated on the open market, with a significant portion funneled through THORChain, a decentralized liquidity protocol, in a single day.
Who is the Lazarus Group?
The Lazarus Group, also known as APT38 or Hidden Cobra, is a North Korean state-sponsored cybercrime organization linked to the country’s Reconnaissance General Bureau. Active since at least 2009, the group has been responsible for some of the largest cyber heists in history, including:
- $1.5 billion from Bybit (2025)
- $625 million from Ronin Network (2022)
- $100 million from Harmony’s Horizon Bridge (2022)
- $81 million from Bangladesh Bank (2016)
- $41 million from Stake.com (2023)
Since 2017, the group has stolen an estimated $6 billion in cryptocurrency, targeting exchanges, DeFi platforms, and individual traders. Their tactics include social engineering, phishing, malware, and private key compromises, often exploiting human error to gain access to high-value wallets. The group’s activities are believed to fund North Korea’s nuclear and ballistic missile programs, bypassing international sanctions.
How the Attack Unfolded
The $3.2 million heist followed a pattern typical of Lazarus Group operations:
- Initial Breach: The attacker likely used malware or a phishing campaign to compromise the victim’s wallets. Posts on X suggest the attack targeted multiple wallet types, indicating a high level of sophistication.
- Asset Drainage: The stolen assets, primarily SOL-based tokens, were drained from the victim’s wallets on May 16, 2025. The speed of the attack suggests the use of automated tools or pre-existing access to the victim’s systems.
- Market Dumping: The funds were immediately sold on the open market, causing a rapid liquidation that likely impacted token prices. This move is designed to convert assets into more liquid forms like ETH.
- Cross-Chain Bridging: The proceeds were bridged from Solana to Ethereum, a tactic used to complicate tracking efforts. Blockchain analytics firms like Arkham Intelligence traced these movements, noting the group’s use of THORChain to process at least $605 million in a single day during prior attacks.
- Laundering via Tornado Cash: On June 25, 2025, 400 ETH was sent to Tornado Cash, a mixing service that obscures transaction trails. This aligns with the group’s history of using mixers like Tornado Cash, Sinbad, and Yonmix to launder funds.
Why This Matters
This $3.2 million hack highlights several critical issues in the crypto ecosystem:
- Evolving Threat Landscape: The Lazarus Group’s shift toward targeting individual traders, as opposed to just exchanges or DeFi protocols, signals a broadening of their attack surface. This incident, described as targeting an intraday trader, suggests the group is adapting to exploit retail investors.
- Laundering Sophistication: The group’s ability to launder $1.39 billion in ETH from the Bybit hack in just 10 days demonstrates their advanced money-laundering capabilities. The use of Tornado Cash and THORChain complicates recovery efforts, with only $40 million frozen in the Bybit case.
- Web3 Vulnerabilities: The attack underscores the vulnerabilities of multisig wallets and hot wallets, even for savvy users. The group’s reliance on social engineering and malware highlights the importance of user education and robust security practices.
- Geopolitical Implications: Funds stolen by the Lazarus Group are believed to support North Korea’s weapons programs, raising concerns about the intersection of cybercrime and global security.
How to Protect Yourself
To avoid falling victim to similar attacks, consider these best practices:
- Use Cold Wallets: Store assets in offline hardware wallets to protect against online hacks.
- Enable Two-Factor Authentication (2FA): Add an extra layer of security to your accounts and wallets.
- Beware of Phishing: Verify URLs and avoid clicking unsolicited links or sharing sensitive information. The Lazarus Group frequently uses fake job offers and phishing emails to gain access.
- Regularly Update Software: Keep wallets and exchange apps updated with the latest security patches.
- Monitor Wallet Activity: Use blockchain explorers or analytics tools to track suspicious transactions in real-time.
- Avoid Overexposure: Limit the amount of funds stored in hot wallets or on exchanges to reduce risk.
What’s Next?
The Lazarus Group’s continued success in executing high-value heists, including this $3.2 million attack, highlights the need for stronger security measures across the crypto industry. Blockchain analytics firms like Elliptic, Chainalysis, and Arkham Intelligence are working with exchanges and law enforcement to track and freeze stolen funds, but the group’s expertise in laundering makes recovery challenging.
The Bybit hack earlier in 2025, which saw $1.5 billion stolen, prompted Bybit’s CEO to launch a bounty program to trace funds, with $40 million frozen so far. Similar efforts may emerge in response to this incident, but the chances of recovering the full $3.2 million are slim given the group’s use of Tornado Cash.
For the broader crypto community, this attack serves as a wake-up call. As ZachXBT noted, the Lazarus Group’s tactics are evolving, targeting individual traders and leveraging Web3’s inherent vulnerabilities. Enhanced cross-border cooperation, blockchain monitoring, and anti-money laundering (AML) measures are critical to combating this threat.
Final Thoughts
The alleged $3.2 million theft by the Lazarus Group is a stark reminder of the risks in the crypto space. While the industry offers immense opportunities, it remains a prime target for sophisticated cybercriminals like the Lazarus Group. Users must prioritize security, and exchanges must strengthen their defenses to prevent further losses. As the crypto ecosystem evolves, so too must our approach to protecting it.
Stay vigilant, secure your assets, and keep an eye on blockchain analytics for updates on this ongoing saga. The fight against cybercrime in Web3 is far from over.
