Most individuals have participated in a crypto exchange at least once in their lifetime.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Crypto-assets can potentially make individuals millionaires in a flash, but the blockchain technology behind them &#8211; which offers substantial anonymity and security &#8211; isn&#8217;t immune to cybercrime. In the past year, there have been various reports of colossal crypto breaches, as highlighted in this blog.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Cryptocurrencies have been in existence for a relatively long period now. <a href=\"https:\/\/bitcoin.org\/en\/\" target=\"_blank\" rel=\"noreferrer noopener\">Bitcoin<\/a>, the first and largest, was founded in 2009.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">So, it is understandable that such new technologies have faced numerous challenges and faced setbacks due to the incidence of theft and hacking of crypto-assets.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">For example, in its heyday, Bitcoin alone was valued at an eye-watering market capitalization of $1.28 trillion and its unrivaled security provided by blockchain technology only made it even more appealing to investors.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">This in turn, combined with the ignorance of many crypto-investors about blockchain, made them easy targets for <a href=\"https:\/\/reconcybersecurity.com\/\"><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-luminous-vivid-amber-color\">hacking<\/mark><\/strong><\/a>, leading to a series of high-profile crypto hacks, some of which have been the biggest of all time. <\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Let&#8217;s take a closer look at what has occurred in these incidents and the impact that they have had.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"has-black-color has-text-color has-large-font-size\">Ronin Network was funded with an incredible $625 million.<\/p>\n<\/blockquote>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">In spite of the vast potential of crypto-assets to enrich investors, the blockchain technology that underlies them is still susceptible to cybercrime, as evidenced by the Top 3 Largest Cryptocurrency Hacks in History. <\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Over the past year, cybercriminals have exploited vulnerabilities with their advanced techniques to raid digital wallets and purloin significant sums, leaving investors aghast and confounded.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">According to Ronin Network, this heist compromised the validator nodes of Sky Mavis, the programmer of <em>Axi<\/em> Infinity, a top crypto game of that era.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">What&#8217;s worse is that neither Ronin Network nor Sky Mavis was aware that the breach had occurred until one individual reported they could not withdraw their digital money from the system.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">The vulnerability that enabled the hack became even more clear as, shortly before, Ronin Network had decreased its security level due to the rollout of a big Axi Infinity update. <\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Hackers used this chance to gain access to wallets&#8217; private keys and falsify transfers. This would have been avoidable if Ronin Network had maintained higher security protocols to release the update.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"662\" height=\"442\" src=\"https:\/\/reconcybersecurity.com\/blogs\/wp-content\/uploads\/2023\/04\/d969bd790b-edited.jpg\" alt=\"Top 3 Largest Cryptocurrency Hacks in History\" class=\"wp-image-10990\" srcset=\"https:\/\/reconcybersecurity.com\/blogs\/wp-content\/uploads\/2023\/04\/d969bd790b-edited.jpg 662w, https:\/\/reconcybersecurity.com\/blogs\/wp-content\/uploads\/2023\/04\/d969bd790b-edited-300x200.jpg 300w, https:\/\/reconcybersecurity.com\/blogs\/wp-content\/uploads\/2023\/04\/d969bd790b-edited-380x254.jpg 380w\" sizes=\"auto, (max-width: 662px) 100vw, 662px\" \/><\/figure>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Afterward, Ronin Network and Sky Mavis collaborated with multiple U.S. authorities in a bid to recover the stolen assets but could not get back any major amounts. <a href=\"https:\/\/www.binance.com\/en\" target=\"_blank\" rel=\"noreferrer noopener\">Binance<\/a>, on the other hand, retrieved $5.8 million, a trifling sum in comparison. <\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Upon conclusion of the investigation, North Korean cyber criminals working out of China were suspected to be the perpetrators of the theft, leaving the U.S. powerless to act.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"has-black-color has-text-color has-large-font-size\">Poly Network was funded with an incredible $611 million.<\/p>\n<\/blockquote>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Not every hack needs to have a sorrowful conclusion, and the Poly Network hacking episode is a perfect case of that. This hack occurred on August 10th, 2021, when a cyber criminal effectively stole more than $600 million worth of cryptocurrency from the Defi platform.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">As per the reports, the hack may have resulted from an unintentional disclosure of the private keys that were employed to authenticate transactions on the Poly Network wallets.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Further reports detailed that the hacker exploited a bug in the Poly Network code that permitted them to sign transactions without requiring any private keys.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">All in all, about $611 million worth of crypto vanished, including tokens such as wrapped <strong>Ethereum <\/strong>and <strong>Bitcoin<\/strong>, <strong>USDT<\/strong>, and <strong>Shiba Inu<\/strong>.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">To trace and track the stolen assets, Poly Network shared the address of the crypto wallets where funds were transferred and encouraged different exchanges and networks to be vigilant. This eventually resulted in Tether freezing around $33 million of USDT.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Fortunately, this story has a satisfying outcome. After the hacking incident, Poly Network attempted to establish contact with the hacker through various online channels, and remarkably, they received a response.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">The hacker declared that they meant to return all the stolen cryptos and only wanted to reveal the network&#8217;s vulnerabilities.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Following this, the hacker started the process of restoring the stolen funds and by August 13th, had returned around $340 million worth of crypto, with the leftover tokens being shared between Poly Networks and the hacker through multi-signature wallets.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">By August 25, Poly Network was back in the ownership of all the $611 million worth of crypto and offered the hacker a bounty of $500,000 for locating the bug.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Additionally, they also extended the offer for a position as head of cyber security to the hacker, although it remains unknown whether the offer was accepted.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"has-black-color has-text-color has-large-font-size\">The infamous Mt. Gox-$473 million<\/p>\n<\/blockquote>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">One of the most memorable <a href=\"https:\/\/reconcybersecurity.com\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-luminous-vivid-orange-color\">cyber-attacks<\/mark><\/strong><\/a> to ever occur in the cryptocurrency industry happened in 2011, when Mt. Gox, then one of the world&#8217;s largest crypto exchanges, suffered the loss of roughly 25,000 Bitcoin which had an equivalent value of $400,000 at the time.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">However, this event wasn&#8217;t a learning experience for Mt. Gox as the same year, hackers made away with an extra 650,000 Bitcoin from customers, and 100,000 from the exchange itself, valued at around $473 million.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">During the 2011 attack, cybercriminals managed to exploit Mt. Gox&#8217;s security system, manipulating the price of one Bitcoin to just one cent, allowing some users to capitalize on this price manipulation.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Post-2011, Mt. Gox claimed to have heightened its security protocols but it soon fell victim to another hack in 2014.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">After further investigation, it was found that the 2011 attack was responsible for the decryption of numerous Mt. Gox private keys that were then used to extract the subsequent funds in 2014.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">What is so perplexing about the 2014 attack is that it went on undetected for over three years. Speculations have been made that by 2013, Mt. Gox had already been robbed of the majority of their Bitcoin, yet nothing was ever done about it.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Ex-employees have even claimed that Mt. Gox&#8217;s lack of management is to blame for this as it allowed the hackers to steal cryptocurrency unnoticed for an extensive amount of time.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Following the hack&#8217;s discovery, it is reported that Mt. Gox was able to recuperate around 200,000 Bitcoin but unfortunately, the customers are still yet to get their crypto back after eight long years.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"These are Top 3 Largest Cryptocurrency Hacks in History Top 3 Largest Cryptocurrency Hacks in History: Cryptocurrencies have&hellip;\n","protected":false},"author":1,"featured_media":10755,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[241],"tags":[394,395,347,396,240,311],"class_list":{"0":"post-8884","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-it-knowledge","8":"tag-crypto","9":"tag-cryptocurrency-hack","10":"tag-cryptocurrency-miners","11":"tag-cryptocurrency-world","12":"tag-cyber-security","13":"tag-recon-cyber-security"},"_links":{"self":[{"href":"https:\/\/reconcybersecurity.com\/blogs\/wp-json\/wp\/v2\/posts\/8884","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/reconcybersecurity.com\/blogs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/reconcybersecurity.com\/blogs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/reconcybersecurity.com\/blogs\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/reconcybersecurity.com\/blogs\/wp-json\/wp\/v2\/comments?post=8884"}],"version-history":[{"count":3,"href":"https:\/\/reconcybersecurity.com\/blogs\/wp-json\/wp\/v2\/posts\/8884\/revisions"}],"predecessor-version":[{"id":10993,"href":"https:\/\/reconcybersecurity.com\/blogs\/wp-json\/wp\/v2\/posts\/8884\/revisions\/10993"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/reconcybersecurity.com\/blogs\/wp-json\/wp\/v2\/media\/10755"}],"wp:attachment":[{"href":"https:\/\/reconcybersecurity.com\/blogs\/wp-json\/wp\/v2\/media?parent=8884"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/reconcybersecurity.com\/blogs\/wp-json\/wp\/v2\/categories?post=8884"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/reconcybersecurity.com\/blogs\/wp-json\/wp\/v2\/tags?post=8884"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
