Cryptocurrency users lost nearly $500 million to wallet drainer malware throughout 2024, according to a comprehensive report released by anti-scam platform Scam Sniffer on January 6, 2025. The findings reveal a disturbing escalation in phishing-based theft that demands immediate attention from anyone holding digital assets.
The report confirms that approximately $494 million was stolen from more than 332,000 compromised wallet addresses, marking a 67% year-over-year increase in losses. The largest single theft reached $55.48 million, underscoring the devastating potential of these attack vectors.
The Exploit Mechanics
Wallet drainers operate by tricking victims into signing malicious blockchain transactions. Unlike traditional malware that steals private keys directly, wallet drainers exploit the trust users place in their wallet interfaces. Victims encounter phishing websites that closely mimic legitimate decentralized applications, and when they connect their wallets and approve what appears to be a routine transaction, the drainer contract empties their assets.
According to Scam Sniffer, over 90% of the total losses came from a small number of high-value incidents. Just 30 individual attacks accounted for $171 million in combined losses, with the two largest attacks occurring in August and September 2025, stealing $55.48 million and $32.51 million respectively.
The first quarter of 2024 saw the highest concentration of attacks, with 175,000 victims losing a combined $187.2 million. Activity decreased in subsequent quarters as major drainer operations like Pink and Inferno exited the scene, but the overall damage remained substantial.
Affected Systems
The attacks primarily targeted users of browser-based wallet extensions such as MetaMask, Phantom, and Trust Wallet. Ethereum and EVM-compatible networks bore the brunt of the losses, though Solana users were also significantly affected. The phishing infrastructure leveraged compromised advertising networks, fake social media accounts, and impersonated customer support channels to distribute malicious links.
Chainalysis data corroborates the broader trend, revealing that more than $2.2 billion in total cryptocurrency was stolen across all attack vectors in 2024. North Korean state-sponsored hackers were blamed for a significant portion of these losses, including a $308 million theft from Bitcoin exchange DMM.com in December.
The Mitigation Strategy
Security experts recommend a multi-layered defense against wallet drainers. First, users should always verify the URL of any decentralized application before connecting their wallet. Bookmarking frequently used protocols eliminates the risk of landing on phishing sites through search engine results.
Second, hardware wallets provide critical protection. Even if a user signs a malicious transaction on their computer, hardware wallets require physical confirmation on the device, giving users a chance to review the actual transaction details before approval.
Third, revoking unnecessary token approvals on a regular basis limits the blast radius of any successful drainer attack. Tools like Revoke.cash and Unrekt allow users to audit and remove permissions granted to smart contracts.
Lessons Learned
The 2024 wallet drainer epidemic demonstrates that user education remains the weakest link in cryptocurrency security. Despite advances in smart contract auditing and exchange security, individual users continue to fall victim to increasingly sophisticated social engineering attacks.
The exit of major drainer operations like Pink and Inferno in mid-2024 did reduce attack frequency, but new operations quickly filled the void. The 67% increase in losses suggests that the economics of wallet drainers remain highly favorable for attackers.
User Action Required
With Bitcoin trading above $102,000 and Ethereum above $3,680 at the time of this report, the stakes have never been higher. Users should immediately audit their wallet permissions, enable transaction simulation features in their wallet software, and consider migrating high-value holdings to hardware wallet storage.

Mass adoption is happening incrementally — people just don’t notice
332K wallet addresses drained for $494M. 67% increase from 2023. and that is just what got reported. the real number is easily double
the 67% YoY increase is just from tracked drainers. there are copycat kits on telegram going for $200/month that dont even get counted
Interesting perspective — I hadn’t considered that angle before
30 individual attacks accounting for $171M. the two largest in august and september 2025 stole $55M and $32M. wallet drainers are industrial scale operations now not script kiddies
$55M single theft from one wallet drainer. thats more than most defi hacks and it came from phishing not a smart contract exploit
Education is still the biggest barrier to mainstream adoption
