Attackers are utilizing <code>OP_RETURN<\/code> outputs\u2014an optional script field in Bitcoin transactions capable of carrying small amounts of arbitrary data\u2014to broadcast their malicious payloads to anyone inspecting historical blockchain data or tracking legacy wallets.<\/p>\n<p>The alarming campaign underscores the evolving tactics employed by bad actors in the digital asset ecosystem, leveraging psychological pressure, faux legal authority, and advanced social engineering to trick high-value targets into compromising their private keys or surrendering sensitive personal information.<\/p>\n<h3>Targeting Legendary Dormant Wallets<\/h3>\n<p>In one prominently documented case highlighted by the security analysts, the orchestrators of the scam targeted the famous &quot;1Feex&quot; wallet. This heavily monitored address holds approximately 80,000 Bitcoin, a massive fortune that historical blockchain analysis ties to the catastrophic 2011 hack of the now-defunct Mt. Gox exchange. <\/p>\n<p>Rather than attempting a direct cryptographic exploit, which remains practically impossible given Bitcoin&#8217;s robust underlying security architecture, the attackers utilized the <code>OP_RETURN<\/code> mechanism to embed a custom, deceptive message within the blockchain. This on-chain artifact directs curious observers or legacy wallet monitors to a fraudulent web domain meticulously designed to impersonate Salomon Brothers, the legendary and historic Wall Street investment bank.<\/p>\n<p>Upon navigating to the phishing portal, visitors are greeted by a fabricated legal notice asserting that the targeted cryptocurrency wallet is officially classified as &quot;lost or abandoned.&quot; The site relies heavily on intimidation and urgency, warning that failure to act will result in the permanent forfeiture of funds. <\/p>\n<p>To create an illusion of legitimacy, the fraudulent platform invites supposed rightful owners of the ancient Bitcoin to verify their identity and establish ownership claims. The site outlines two primary methods for doing so: signing an on-chain cryptographic message using the wallet&#8217;s original private key\u2014which would instantly expose the private key to the attackers\u2014or submitting comprehensive personal documentation through an embedded web contact form. The notice establishes a strict deadline of October 5, claiming that any address failing to respond by this date will be deemed legally abandoned and subject to reallocation.<\/p>\n<h3>Fabricated Legal Claims and Phantom Advisors<\/h3>\n<p>BitMEX Research thoroughly investigated the claims made by the phishing portal and quickly established that the website possesses zero credible connection to the real Salomon Brothers or its historic corporate leadership. <\/p>\n<figure class=\"article-inline-figure\"><img decoding=\"async\" src=\"https:\/\/cryptoslate.com\/wp-content\/uploads\/2025\/07\/scammer-bitcoin-1.jpg\" alt=\"Scam targets dormant Bitcoin wallets with fake legal notice\" class=\"article-inline-img\" loading=\"lazy\" \/><\/figure>\n<p>While the fraudulent operators attempted to launder their reputation by publishing a list of genuine individuals who previously worked at the investment bank during the 1980s, security analysts confirmed that these former Wall Street executives have absolutely no association with the newly minted and spurious entity running the scam. The inclusion of these real names represents a calculated social engineering tactic designed to deceive investigators and potential victims into trusting the validity of the legal warning.<\/p>\n<p>Furthermore, industry observers have noted tactical similarities between this current campaign and past legal controversies surrounding the &quot;1Feex&quot; address. Analysts pointed out that the approach bears a striking resemblance to earlier speculative maneuvers involving high-profile industry figures, such as Calvin Ayre, who previously funded complex legal actions attempting to lay claim to the exact same disputed Bitcoin balance. However, security experts emphasize that regardless of any historical legal battles surrounding the Mt. Gox fallout, the current website is entirely fraudulent and operates purely as a phishing vehicle.<\/p>\n<p>BitMEX Research issued a direct advisory regarding the campaign, stating that the associations claimed by the website are completely fabricated. &quot;The links between this company and this website are fake,&quot; the firm noted, highlighting the deceptive inclusion of the 1980s advisory board roster. &quot;There is a page with an &#8216;advisory board&#8217; that contains real people who worked at Salomon Brothers in the 1980s, however, these people seem to have no link to this new spurious entity.&quot;<\/p>\n<h3>Broader Implications for Crypto Security<\/h3>\n<p>As news of the campaign spread across blockchain intelligence circles and social media platforms, cryptocurrency community members quickly weighed in with technical insights. Experienced developers and security researchers pointed out that legitimate wallet owners wishing to prove activity or operational control do not need to interact with suspicious third-party legal forms or expose sensitive credentials. Instead, standard network verification can be accomplished simply by broadcasting a minuscule transaction of a fraction of a Satoshi from the wallet in question, instantly proving current private key access without risking the entire balance.<\/p>\n<p>This practical observation has reinforced suspicions across the broader cybersecurity community that the campaign is not genuinely designed to adjudicate legal ownership claims. Rather, security professionals suspect it is part of a much broader, highly targeted social engineering effort aimed at extracting sensitive personal identifiable information or manipulating legacy holders into revealing private keys under the false pretense of compliance with regulatory or legal mandates.<\/p>\n<p>Security analysts have reiterated stern warnings advising all cryptocurrency holders, particularly those managing early-era or long-dormant addresses, to completely ignore these on-chain injections. Users are strongly urged never to interact with unverified contact forms, click links embedded within suspicious blockchain transactions, or input private keys into web-based portals regardless of how authoritative or official the associated legal notices may appear.<\/p>\n<p>The emergence of this sophisticated phishing scheme arrives against the backdrop of an increasingly hostile threat landscape within the digital asset economy. According to recent industry tracking data, the growing complexity and frequency of crypto-related fraud have placed immense pressure on both institutional custodians and individual investors. During the first half of the year alone, malicious actors and state-backed hacking syndicates successfully stole over $2.1 billion across 75 distinct security incidents, representing a notable 10% increase in total losses compared to the corresponding period in the previous year. As attackers continue to pioneer novel vectors ranging from on-chain data injection to elaborate social engineering campaigns, the latest BitMEX Research warning serves as a stark reminder of the persistent vigilance required to navigate the cryptocurrency ecosystem safely.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Analysts at BitMEX Research have raised a critical security alarm regarding an emerging and sophisticated&#8230;<\/p>\n","protected":false},"author":7,"featured_media":1343,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[578],"tags":[1278,25,1358,581,680,296,529,1013,184,580,214,532,579,530,814,115,348],"class_list":["post-1344","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-fraud-scams","tag-addresses","tag-bitcoin","tag-bitmex","tag-dormant","tag-early","tag-fraud","tag-holders","tag-lost","tag-phishing","tag-prevention","tag-research","tag-scam","tag-scams","tag-sophisticated","tag-targeting","tag-wallet","tag-warns"],"_links":{"self":[{"href":"https:\/\/smartcryptosecurity.com\/index.php?rest_route=\/wp\/v2\/posts\/1344","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/smartcryptosecurity.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/smartcryptosecurity.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/smartcryptosecurity.com\/index.php?rest_route=\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/smartcryptosecurity.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1344"}],"version-history":[{"count":0,"href":"https:\/\/smartcryptosecurity.com\/index.php?rest_route=\/wp\/v2\/posts\/1344\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/smartcryptosecurity.com\/index.php?rest_route=\/wp\/v2\/media\/1343"}],"wp:attachment":[{"href":"https:\/\/smartcryptosecurity.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1344"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/smartcryptosecurity.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1344"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/smartcryptosecurity.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1344"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
