Nothing about it exploits a bug in Solana or in your wallet: the transaction is valid, the signature is yours, and the transfer is final.

You connect your wallet, which reveals your address but moves nothing. The site then queries the chain to see exactly what you hold, ranks it by value, and builds a transaction targeting the most valuable assets specifically.<\/p>\n\n\n\n<p>Then it presents that transaction with a friendly label: &#8220;Claim&#8221;, &#8220;Verify&#8221;, &#8220;Enable trading&#8221;. You approve, and the bundled instructions transfer your tokens, sweep your SOL, and in some cases grant SetAuthority over your token accounts so anything arriving later can be taken too. On Solana this happens in one slot, sub-second, and is irreversible. The delivery half of that funnel is covered in <a href=\"\/blog\/fake-airdrop-scams-solana\/\">how fake airdrops are constructed<\/a>; this is the payload half.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why the Numbers Moved<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Period<\/th><th>Losses<\/th><th>Wallets affected<\/th><th>What changed<\/th><\/tr><\/thead><tbody><tr><td>2024<\/td><td>~$494M<\/td><td>332,000+<\/td><td>Peak of drainer-as-a-service growth<\/td><\/tr><tr><td>2025<\/td><td>~$83.85M<\/td><td>106,106<\/td><td>~83% decline as wallets added warnings<\/td><\/tr><tr><td>January 2026<\/td><td>$6.27M in one month<\/td><td>4,741<\/td><td>Signature phishing up 207% month on month<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>The 2025 drop is real progress and worth understanding correctly: wallets started simulating transactions and flagging known malicious domains, which removed the easiest version of the attack. The January 2026 spike shows what followed \u2014 attackers moved toward signature phishing, where the request looks like an innocuous message signing rather than a transfer. Defences shift the technique rather than ending it, so a wallet warning you did not see is not the same as a transaction that was safe.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Actually Stops a Drainer<\/h2>\n\n\n\n<p>Reading the transaction before approving is the only defence that works at the moment of attack. Modern wallets simulate and show expected balance changes: if a &#8220;claim&#8221; shows assets leaving your wallet, that is the answer. If the simulation cannot render the transaction at all, reject it \u2014 an unreadable instruction set under time pressure is the standard shape, not an edge case.<\/p>\n\n\n\n<p>Everything else reduces exposure rather than preventing approval. Keeping risky activity in <a href=\"\/blog\/burner-wallet-solana\/\">a separate burner address<\/a> means a successful drain costs a small balance. Reaching sites by typing the domain rather than following links removes lookalike domains and paid search results. And periodically checking that no delegate or authority was granted \u2014 the routine in <a href=\"\/blog\/revoke-token-approvals-solana\/\">revoking approvals and delegates<\/a> \u2014 catches the slower variant where access is planted for later.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">If It Already Happened<\/h2>\n\n\n\n<p>Move whatever remains to a wallet generated from a completely new seed phrase, immediately, before hunting for what went wrong. Then check the compromised address on <a href=\"https:\/\/solscan.io\" rel=\"nofollow\">Solscan<\/a> to see which instructions ran and whether ownership of any token account was transferred. Abandon the address rather than continuing to use it, because confirming that no lingering authority remains is harder than starting fresh. If tokens remain that are worth moving, route the exit through <a href=\"https:\/\/jup.ag\" rel=\"nofollow\">Jupiter<\/a> in one pass rather than several transactions. Ignore anyone who contacts you afterwards offering recovery \u2014 that is a second scam aimed at the same victim.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Token Choice Does Not Protect You<\/h2>\n\n\n\n<p>DOLAN Duck ($DOLAN) has a fixed 98.3M supply, roughly 10,700 holders, no mint authority and no freeze authority \u2014 and none of that is relevant to a drainer, because a drain does not attack the token. It attacks the wallet holding it, and a token with perfect on-chain hygiene sitting in a compromised address is taken exactly as easily as one without. This is the distinction worth carrying away from the whole security cluster: token-level checks tell you whether a project can harm you, while wallet-level discipline determines whether anyone else can. Both are necessary and neither substitutes for the other.<\/p>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1754644601\"><strong class=\"schema-faq-question\">What is a crypto drainer?<\/strong> <p class=\"schema-faq-answer\">A crypto drainer is packaged software that empties a wallet when its owner signs one prepared transaction.
