According to initial reports, nearly <strong>54 billion South Korean won were siphoned<\/strong> to an unidentified external address.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-rich is-provider-twitter wp-block-embed-twitter\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"twitter-tweet\" data-width=\"500\" data-dnt=\"true\"><p lang=\"en\" dir=\"ltr\">Upbit(<a href=\"https:\/\/twitter.com\/Official_Upbit?ref_src=twsrc%5Etfw\">@Official_Upbit<\/a>) has been hacked \u2014 54B KRW (~36.8M USD) in assets on <a href=\"https:\/\/twitter.com\/hashtag\/Solana?src=hash&amp;ref_src=twsrc%5Etfw\">#Solana<\/a> have been transferred to unknown wallets.<a href=\"https:\/\/t.co\/plbmBz2G4N\">https:\/\/t.co\/plbmBz2G4N<\/a><a href=\"https:\/\/t.co\/YOHoqDVfqa\">https:\/\/t.co\/YOHoqDVfqa<\/a> <a href=\"https:\/\/t.co\/DM5BxSTtXA\">pic.twitter.com\/DM5BxSTtXA<\/a><\/p>&mdash; Lookonchain (@lookonchain) <a href=\"https:\/\/twitter.com\/lookonchain\/status\/1993904734546300942?ref_src=twsrc%5Etfw\">November 27, 2025<\/a><\/blockquote><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script>\n<\/div><\/figure>\n\n\n\n<p>Upbit&#8217;s response was relatively swift. The <a href=\"https:\/\/investx.fr\/en\/crypto-news\/exchanges\/\">exchange<\/a> immediately <strong>proceeded to secure the compromised wallets<\/strong> and published a statement reassuring its users. The platform states that this loss will be entirely absorbed by its own reserves, with no impact on client balances. This approach echoes that adopted during other major industry incidents. Where some platforms chose to socialize losses while others, like Upbit, directly assume the cost of the breach.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"peckshield-detects-the-breach-timeline-of-a-lightning-hack\">PeckShield Detects the Breach: Timeline of a Lightning Hack<\/h2>\n\n\n\n<p><strong>PeckShield<\/strong> played a decisive role in the early identification of this violation. The cybersecurity firm, experienced in on-chain analysis, spotted abnormal transfers involving Solana tokens from Upbit&#8217;s hot wallets. Analysts noticed that <strong>the funds were moved in several closely-timed transactions<\/strong>. A classic signature of automated attacks or private key compromises.<\/p>\n\n\n\n<p>This type of breach raises major technical questions. How did the attackers manage to <strong>access the hot wallets without triggering alert systems earlier?<\/strong> Exchanges typically use <strong>multi-signature mechanisms<\/strong> and progressive withdrawal controls to limit exposure. Yet, in this specific case, the hackers appear to have circumvented these safeguards with formidable efficiency.<\/p>\n\n\n\n<p>The <strong>Solana<\/strong> blockchain, despite its speed and low transaction costs, also presents <strong>specific characteristics in terms of wallet management and security<\/strong>. Unlike Ethereum where custody solutions are <strong>more mature and diversified,<\/strong> the Solana ecosystem is still developing on certain security aspects. This attack could therefore highlight <strong>vulnerabilities<\/strong> specific to the technical infrastructure used by Upbit to manage its <strong>SPL<\/strong> assets.<\/p>\n\n\n\n<p>Store your Solana tokens on <strong>cold wallets<\/strong> to protect yourself against attacks. This is the ideal opportunity since <strong>Ledger<\/strong> is offering <strong>50% discounts and up to $90 of BTC<\/strong> for any Ledger purchase with our exclusive Black Friday offer:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a class=\"https:\/\/investx.fr\/visiter-ledger\" href=\"https:\/\/investx.fr\/visiter-ledger\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" width=\"744\" height=\"418\" src=\"https:\/\/investx.fr\/en\/wp-content\/uploads\/sites\/5\/2025\/11\/image-122.png\" alt=\"A smartphone with a Ledger Nano X on black background for Black Friday offer \" class=\"wp-image-22591\" srcset=\"https:\/\/media.investx.fr\/wp-content\/uploads\/sites\/5\/2025\/11\/image-122.png 744w, https:\/\/media.investx.fr\/wp-content\/uploads\/sites\/5\/2025\/11\/image-122-300x169.png 300w\" sizes=\"(max-width: 744px) 100vw, 744px\" \/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"upbit-promises-total-compensation-crisis-management-strategy\">Upbit Promises Total Compensation: Crisis Management Strategy<\/h2>\n\n\n\n<p>Faced with this incident, Upbit opted for transparent and reassuring communication. The exchange clearly stated that members&#8217; assets <strong>will not be affected<\/strong>, a crucial commitment to preserve user confidence. This decision to fully cover the loss with its own funds demonstrates solid financial health and a responsible approach to risk management.<\/p>\n\n\n\n<p>Historically, Upbit had already been the victim of a major hack <strong>in 2019<\/strong>, where <strong>342,000 ETH<\/strong> were stolen, worth approximately <strong>$50 million at the time.<\/strong> The platform had also reimbursed its users then, strengthening its reputation for reliability. This new attack, although significant, remains lower in absolute value, but it occurs in a context where the security of centralized exchanges is <strong>closely scrutinized by regulators and the community.<\/strong><\/p>\n\n\n\n<p>Upbit&#8217;s teams announced the launch of an <strong>in-depth investigation in collaboration with South Korean authorities<\/strong> and blockchain security partners. The objective is twofold: identify the attack vectors used and strengthen existing security protocols. Investigations could also focus on the traceability of stolen funds, with the hope of freezing part of the assets through collaborations with other exchanges and Solana development teams.<\/p>\n\n\n\n<p><strong>Related articles:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/investx.fr\/en\/crypto-news\/shiba-inu-shib-outperforms-bitcoin-whats-behind-remarkable-surge\/\">Shiba Inu (SHIB) outperforms Bitcoin: What\u2019s behind this remarkable surge?<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/investx.fr\/en\/2025\/11\/26\/is-bitcoin-the-perfect-investment-opportunity-now\/\">Is Bitcoin the perfect investment opportunity now?<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/investx.fr\/en\/crypto-news\/monad-has-finally-launched-mon-token-everything-you-need-know-about-explosive-release\/\">Monad has finally launched its MON token: Everything you need to know about this explosive release<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>South Korean exchange Upbit has experienced a major security breach involving 54 billion wons in Solana assets, approximately $37 million transferred to an unauthorized wallet.
