	"plain_text": "Revamped CryptBot malware spread by pirated software sites\r\nBy Bill Toulas\r\nPublished: 2022-02-21 · Archived: 2026-04-10 03:16:21 UTC\r\nA new version of the CryptBot info stealer was seen in distribution via multiple websites that offer free downloads\r\nof cracks for games and pro-grade software.\r\nCryptBot is a Windows malware that steals information from infected devices, including saved browser\r\ncredentials, cookies, browser history, cryptocurrency wallets, credit cards, and files.\r\nThe latest version features new capabilities and optimizations, while the malware authors have also deleted several\r\nolder functions to make their tool leaner and more efficient.\r\nSecurity analysts at Ahn Lab reported that the threat actors are constantly refreshing their C2, dropper sites, and\r\nthe malware itself, so CryptBot is currently one of the most shifting malicious operations.\r\nhttps://www.bleepingcomputer.com/news/security/revamped-cryptbot-malware-spread-by-pirated-software-sites/\r\nPage 1 of 4\n\nUsing search results for delivery\r\nAccording to the Ahn Lab report, the CryptBot threat actors distribute malware through websites pretending to\r\noffer software cracks, key generators, or other utilities. \r\nTo gain wide visibility, the threat actors utilize search engine optimization to rank the malware distribution sites at\r\nthe top of Google search results, providing a stable stream of prospective victims.\r\nAccording to screenshots shared of the malware distribution sites, the threat actors use both custom domains or\r\nwebsites hosted on Amazon AWS.\r\nSome of the websites used recently for CryptoBot distribution\r\nSource: Ahn Lab\r\nThe malicious websites are constantly being refreshed, so there’s a wide variety of ever-shifting lures to draw\r\nusers onto the malware distribution sites. \r\nVisitors of these sites are taken through a series of redirections before they end up on the delivery page, so the\r\nlanding page could be on a compromised legitimate site abused for SEO poisoning attacks.\r\nWe have seen the same malware operators using fake VPN sites to deliver CryptBot to victims in previous years,\r\nso search engine abuse isn't a new trick.\r\nFeatures removed\r\nFresh samples of CryptBot indicate that its authors want to simplify its functionality and make the malware\r\nlighter, leaner, and less likely to be detected.\r\nIn this context, the anti-sandbox routine has been removed, leaving only the anti-VM CPU core count check in the\r\nnewest version.\r\nAlso, the redundant second C2 connection and second exfiltration folder were both removed, and the new variant\r\nonly features a single info-stealing C2.\r\n\"The code shows that when sending files, the method of manually adding the sent file data to the header was\r\nchanged to the method that uses simple API. user-agent value when sending was also modified,\" explains\r\nASEC's report\r\nhttps://www.bleepingcomputer.com/news/security/revamped-cryptbot-malware-spread-by-pirated-software-sites/\r\nPage 2 of 4\n\n\"The previous version calls the function twice to send each to a different C2, but in the changed version, one C2\r\nURL is hard-coded in the function.\"\r\nAnother feature the CryptBot’s authors have scrapped is the screenshot function and the option of collecting data\r\non TXT files on the desktop, which were too risky and perhaps easily detected during exfiltration.\r\nWorks on all Chrome versions\r\nOn the other hand, the latest version of CryptBot brings some targeted additions and improvements that make it a\r\nlot more potent.\r\nIn previous versions, the malware could only successfully exfiltrate data when deployed against Chrome versions\r\nbetween 81 and 95.\r\nThis limitation arose from implementing a system that looked for user data in fixed file paths, and if the paths\r\nwere different, the malware returned an error.\r\nPathname discovery system comparison (new right) - ASEC\r\nNow, it searches on all file paths, and if user data is found anywhere, it exfiltrates them regardless of the Chrome\r\nversion.\r\nConsidering that Google rolled out chrome 96 in November 2021, CryptBot remained ineffective against most of\r\nits targets for roughly three months, so fixing this problem was well overdue for its operators.\r\nAs CryptBot primarily targets people searching for software cracks, warez, and other methods of defeating\r\ncopyright protection, simply avoiding the downloading of these tools will prevent infection by this malware and\r\nmany others.\r\nhttps://www.bleepingcomputer.com/news/security/revamped-cryptbot-malware-spread-by-pirated-software-sites/\r\nPage 3 of 4\n\nAutomated Pentesting Covers Only 1 of 6 Surfaces.\r\nAutomated pentesting proves the path exists. BAS proves whether your controls stop it. Most teams run one\r\nwithout the other.\r\nThis whitepaper maps six validation surfaces, shows where coverage ends, and provides practitioners with three\r\ndiagnostic questions for any tool evaluation.\r\nSource: https://www.bleepingcomputer.com/news/security/revamped-cryptbot-malware-spread-by-pirated-software-sites/\r\nhttps://www.bleepingcomputer.com/news/security/revamped-cryptbot-malware-spread-by-pirated-software-sites/\r\nPage 4 of 4",
