The bug gave attackers a path to push fraudulent transactions through <span>nodes<\/span> that had not applied recent updates.<\/p>\n<figure id=\"attachment_809426\" aria-describedby=\"caption-attachment-809426\" style=\"width:1332px\" class=\"wp-caption aligncenter\"><figcaption id=\"caption-attachment-809426\" class=\"wp-caption-text\">Litecoin X post on the subject on April 25, 2026.<\/figcaption><\/figure>\n<p>The 13-block reorg was the network\u2019s response to that exploit. It reversed the invalid transactions and prevented them from being included in the main chain. The <a href=\"https:\/\/news.bitcoin.com\/litecoin-integrates-bitcoinos-for-zk-rollup-cross-chain-utility\/\">Litecoin<\/a> team confirmed that all valid transactions during that period remain unaffected.<\/p>\n<p>The team insists the bug has since been fully patched. The Litecoin network is operating normally as of the team\u2019s statement posted at 4:22 p.m. ET on April 25.<\/p>\n<p>Aurora Labs CEO Alex Shevchenko and onchain analyst <a href=\"https:\/\/x.com\/zacodil\/status\/2048093765731037413\" target=\"_blank\" rel=\"noopener noreferrer\">Zacodil<\/a> had <a href=\"https:\/\/x.com\/AlexAuroraDev\/status\/2048087271262318795?s=20\" target=\"_blank\" rel=\"noopener noreferrer\">flagged<\/a> the reorg earlier in the day, with observers initially interpreting the 13-block reorganization as a classic 51% attack. Onchain timestamps showed those blocks took more than three hours to generate, compared to the normal target of roughly 32 minutes for 13 blocks at Litecoin\u2019s 2.5-minute block time.<\/p>\n<p>The official Litecoin statement reframes what happened. The reorg was allegedly not attackers successfully rewriting history for profit. It was the network correcting a bug-driven exploit by discarding the invalid chain.<\/p>\n<figure id=\"attachment_809434\" aria-describedby=\"caption-attachment-809434\" style=\"width:1572px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-809434 size-full\" title=\"Litecoin Confirms Zero-Day Bug Caused 13-Block Reorg, Network Patched and Stable\" src=\"https:\/\/static.news.bitcoin.com\/wp-content\/uploads\/2026\/04\/reddit_nwmk.png\" alt=\"Litecoin Confirms Zero-Day Bug Caused 13-Block Reorg, Network Patched and Stable\" width=\"1572\" height=\"410\" srcset=\"https:\/\/static.news.bitcoin.com\/wp-content\/uploads\/2026\/04\/reddit_nwmk-300x78.png 300w, https:\/\/static.news.bitcoin.com\/wp-content\/uploads\/2026\/04\/reddit_nwmk-1024x267.png 1024w, https:\/\/static.news.bitcoin.com\/wp-content\/uploads\/2026\/04\/reddit_nwmk-768x200.png 768w, https:\/\/static.news.bitcoin.com\/wp-content\/uploads\/2026\/04\/reddit_nwmk-1536x401.png 1536w, https:\/\/static.news.bitcoin.com\/wp-content\/uploads\/2026\/04\/reddit_nwmk.png 1572w\" sizes=\"auto, (max-width: 1572px) 100vw, 1572px\"\/><figcaption id=\"caption-attachment-809434\" class=\"wp-caption-text\"><a href=\"https:\/\/www.reddit.com\/r\/litecoin\/comments\/1svgsqk\/double_spend\/\" target=\"_blank\" rel=\"noopener noreferrer\">Reddit user<\/a> asking about a double-spend during the Litecoin reorg on April 25 on the r\/litecoin subreddit.<\/figcaption><\/figure>\n<p>NEAR Intents had originally <a href=\"https:\/\/x.com\/AlexAuroraDev\/status\/2048099904938029159?s=20\" target=\"_blank\" rel=\"noopener noreferrer\">reported<\/a> approximately $600,000 in exposure, saying its team would cover any user losses.
