The Foundation said valid transactions made during that period remained unaffected.<\/p>\n<p>Moreover, attackers used the fork window to attempt double-spend transactions against cross-chain swap protocols. These platforms had accepted MWEB peg-outs that later became invalid after the reorganization.<\/p>\n<p>Shevchenko said, \u201cThe exposure for NEAR Intents is around $600k.\u201d He also warned trading venues to review Litecoin transactions and balances, adding, \u201cWe see a lot of double spend transactions.\u201d<\/p>\n<h2 class=\"wp-block-heading\"><strong>Foundation says bug is patched<\/strong><\/h2>\n<p>The Litecoin Foundation said the zero-day bug has now been fully patched. It did not name the affected mining pools or disclose how much LTC the invalid transactions attempted to create.<\/p>\n<p>The attack marks the first known major exploit targeting MWEB since Litecoin activated the privacy feature in May 2022.
