Stablecoin issuer Tether froze balances on all 131 Tron addresses following the designation, rendering the <strong>USDT<\/strong> held there unusable on compliant platforms. ISIS-K, the Islamic State affiliate operating across Afghanistan, Pakistan and parts of Central Asia, solicited crypto donations through its media arm, the al-Azaim Media Foundation, via websites and messaging platforms. Chainalysis identified historical donation addresses across the Tron, Monero and Bitcoin networks, with several of the newly designated wallets routing funds to Syria-based crypto exchangers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The action underscores the growing role of centralized stablecoin issuers as an enforcement instrument. Because Tether controls the token contract, it can render sanctioned funds unspendable almost as fast as OFAC publishes a list \u2014 the company froze more than <strong>$182 million<\/strong> in USDT across five Tron wallets in January under the same compliance policy. The three Monero addresses illustrate the limit of that approach: the privacy coin obscures senders, receivers and amounts at the protocol level and has no central operator, so the designated <strong>XMR<\/strong> wallets remain functional even as U.S. persons are barred from transacting with them.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The same tranche included a separate counter-narcotics action targeting a network tied to Primeiro Comando da Capital, described by the Treasury as Latin America&#8217;s largest criminal gang. OFAC designated two Brazilian nationals and four companies accused of laundering more than <strong>$30 million<\/strong> in U.S.-generated drug proceeds and using crypto to move the funds back to Brazil. The designations follow a June action against six entities and three individuals accused of moving money for ISIS across Europe, the Middle East and West Africa.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For exchanges and other virtual asset service providers, the immediate task is operational: sanctions screening and transaction monitoring must be updated to cover the newly listed addresses. The broader takeaway is structural \u2014 OFAC is leaning harder on onchain identifiers, and the split outcome between Tron and Monero marks the practical boundary of what that strategy can enforce.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The U.S. Treasury&#8217;s Office of Foreign Assets Control added 134 cryptocurrency wallet addresses to its ISIS-Khorasan sanctions entry<\/p>\n","protected":false},"author":2,"featured_media":460,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[2],"tags":[],"class_list":["post-459","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-last-news"],"brizy_media":[],"_links":{"self":[{"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/posts\/459","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=459"}],"version-history":[{"count":1,"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/posts\/459\/revisions"}],"predecessor-version":[{"id":461,"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/posts\/459\/revisions\/461"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/media\/460"}],"wp:attachment":[{"href":"https:\/\/1stblock.info\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=459"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=459"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=459"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
