HiRiBi<\/a>, we offer you to review the 10 most high-profile cases in the history of cryptocurrencies.<\/p>\n\n\n\n1.\u00a0Bybit Hack: $1.5 Billion<\/h2>\n\n\n\n
In\nFebruary 2025, Bybit, one of the largest cryptocurrency exchanges, suffered a\nmassive breach, with hackers stealing over $1.5 billion worth of Ethereum. The\nbreach was made easy by vulnerabilities in Bybit\u2019s multi-signature wallet\nsystem, where the attackers used compromised infrastructure from Safe{Wallet},\na third-party provider. The attack was traced to the Lazarus Group, a North\nKorean state-sponsored hacking collective. <\/p>\n\n\n\n
Despite\nthe significant loss, Bybit was able to acquire emergency funding from firms\nlike Galaxy Digital and Wintermute, replenishing its reserves within 72 hours. <\/p>\n\n\n\n
2.\u00a0Ronin Network (Axie Infinity): $625 Million<\/h2>\n\n\n\n
On\nMarch 23, 2022, the Ronin Network, which supports the popular blockchain game\nAxie Infinity, was hacked for approximately $625 million in Ethereum and USDC.\nThe hack was also traced to the Lazarus Group, which exploited a vulnerability\nin the network’s validator nodes. While Sky Mavis, Axie Infinity’s developer,\nmanaged to recover $5.8 million of the stolen funds, most remain unaccounted\nfor. <\/p>\n\n\n\n
3.\u00a0Poly Network Hack: $610 Million<\/h2>\n\n\n\n
A\nlone hacker exploited Poly Network, a decentralized finance (DeFi) platform, in\nAugust 2021 for $610 million. The hacker took advantage of a vulnerability in\nthe network\u2019s smart contracts, siphoning funds to their wallet. After an appeal\nby the project\u2019s developers on X (formerly Twitter), the hacker cooperated,\nreturning over $300M in just two days. Most of the stolen funds were recovered,\nwith the hacker keeping only $33M USDT. It later emerged that they had targeted\nthe network \u201cfor fun.\u201d <\/p>\n\n\n\n
4.\u00a0Binance BNB Bridge: $569 Million<\/h2>\n\n\n\n
Binance\nsuffered a massive exploit in October 2022 where the attackers made off with\nnearly $569M. The breach targeted BSC Token Hub cross-chain bridge, where a\nvulnerability in a smart contract allowed the hackers to mint 2 million\nunauthorized BNB tokens.<\/p>\n\n\n\n
5.\u00a0Coincheck: $534 Million<\/h2>\n\n\n\n
In\nJanuary 2018, Japanese exchange Coincheck was hacked for $534 million worth of\nNEM tokens. The attackers gained access to the exchange\u2019s hot wallets, which\nlacked proper security measures due to a shortage of employees, according to\nthe exchange. The breach went unnoticed for nearly eight and a half hours.\nCoincheck initially stated that it might not be able to compensate all affected\nusers, but later repaid all 260,000 affected users using its own capital.<\/p>\n\n\n\n
6.\u00a0Mt. Gox Hack: $470 Million<\/h2>\n\n\n\n
Mt.\nGox, once the leading Bitcoin exchange, suffered the first major crypto hack in\n2011, losing 25,000 bitcoins valued at about $400,000. However, the most\ndevastating blow came in 2014 when the platform revealed that nearly 850,000\nBTC, 650,000 belonging to customers and 100,000 to the company, had been stolen,\namounting to approximately $470 million at the time. The breach, which stemmed\nfrom years of undetected theft via the exchange\u2019s hot wallet, exposed severe\nlapses in security and internal oversight. Mt. Gox eventually filed for\nbankruptcy and recently kicked off plans to compensate affected users.<\/p>\n\n\n\n
7.\u00a0Wormhole: $321 Million<\/h2>\n\n\n\n
In\nFebruary 2022, Wormhole, a cross-chain bridge between Ethereum and Solana, was\nexploited for $321 million. The attacker targeted the platform’s smart\ncontract, allowing them to mint unauthorized tokens. This was made possible by\nan upgrade to the project’s GitHub repository, which had not yet gone live.\nJump Crypto, the platform’s backer, stepped in to replace the stolen funds to\nmaintain the project’s integrity. <\/p>\n\n\n\n
8.\u00a0KuCoin: $281 Million<\/h2>\n\n\n\n
The\nKuCoin hack occurred on September 25, 2020, when hackers stole over $281\nmillion worth of cryptocurrency from the exchange. The stolen assets included\nBitcoin, Ethereum, and various ERC-20 tokens. Initially, the hackers attempted\nto sell the stolen tokens on regular exchanges but were quickly blocked. They\nthen turned to decentralized exchanges (DEXs) like Uniswap and Kyber Network to\nlaunder the funds. Despite the use of DEXs, blockchain monitoring tools such as\nElliptic and Chainalysis were still able to trace the stolen funds. KuCoin\nmanaged to recover approximately $204 million of the stolen funds.<\/p>\n\n\n\n
9.\u00a0Bitmart: $196 Million<\/h2>\n\n\n\n
In\nDecember 2021, Bitmart, a global cryptocurrency exchange, became the target of\na massive hack that resulted in the theft of approximately $196 million. The\nhackers accessed Bitmart\u2019s hot wallets by obtaining private keys and draining\nassets from multiple tokens. Although Bitmart pledged to compensate affected\nusers and enhanced its security protocols afterward, the breach exposed the\nvulnerability of exchanges, particularly in the handling of private keys.<\/p>\n\n\n\n
10.\u00a0Bitfinex: $72 Million<\/h2>\n\n\n\n
In\nAugust 2016, Bitfinex exchange was breached, and the hackers made away with\napproximately 119,754 BTC, valued at $72 million at the time. The breach was\nlinked to vulnerabilities in the exchange\u2019s security system, which allowed the\nhackers to make over 2,000 unauthorized transactions. In 2022, U.S. authorities\narrested two individuals in connection with the hack and recovered more than\n75% of the stolen funds. <\/p>\n\n\n\n
Final\nThoughts <\/h2>\n\n\n\n
The\ncrypto industry has come a long way since the early days of these massive\nhacks, but there\u2019s still much to be done to protect users\u2019 assets.\nMulti-signature wallets, better smart contract auditing, and user education on\nhow to securely manage their assets are essential steps forward. As more\ninstitutional investors enter the market, the need for stronger security\nprotocols will only increase. For investors, the key takeaway is to stay\ninformed, diversify holdings, and never underestimate the importance of\nsecuring private keys.<\/p>\n","protected":false},"excerpt":{"rendered":"
The cryptocurrency industry, despite its promise of decentralized finance and strong security, has been marred by significant breaches. Over the past decade, hackers have exploited vulnerabilities in blockchain protocols, decentralized finance (DeFi) platforms, and crypto exchanges, stealing billions of dollars in digital assets.<\/p>\n","protected":false},"author":1,"featured_media":1226,"comment_status":"closed","ping_status":"closed","sticky":true,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[125,71,98,79,104],"class_list":["post-1225","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized","tag-btc","tag-crypto","tag-defi","tag-ethereum","tag-hiribi","entry"],"_links":{"self":[{"href":"https:\/\/hiribi.com\/blog\/wp-json\/wp\/v2\/posts\/1225","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hiribi.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/hiribi.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/hiribi.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/hiribi.com\/blog\/wp-json\/wp\/v2\/comments?post=1225"}],"version-history":[{"count":1,"href":"https:\/\/hiribi.com\/blog\/wp-json\/wp\/v2\/posts\/1225\/revisions"}],"predecessor-version":[{"id":1227,"href":"https:\/\/hiribi.com\/blog\/wp-json\/wp\/v2\/posts\/1225\/revisions\/1227"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/hiribi.com\/blog\/wp-json\/wp\/v2\/media\/1226"}],"wp:attachment":[{"href":"https:\/\/hiribi.com\/blog\/wp-json\/wp\/v2\/media?parent=1225"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/hiribi.com\/blog\/wp-json\/wp\/v2\/categories?post=1225"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/hiribi.com\/blog\/wp-json\/wp\/v2\/tags?post=1225"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
