	"plain_text": "Lazarus Group Exploits Zero-Day Vulnerability to Hack South\r\nKorean Financial Entity\r\nBy The Hacker News\r\nPublished: 2023-03-08 · Archived: 2026-04-05 19:39:37 UTC\r\nThe North Korea-linked Lazarus Group has been observed weaponizing flaws in an undisclosed software to\r\nbreach a financial business entity in South Korea twice within a span of a year.\r\nWhile the first attack in May 2022 entailed the use of a vulnerable version of a certificate software that's widely\r\nused by public institutions and universities, the re-infiltration in October 2022 involved the exploitation of a zero-day in the same program.\r\nCybersecurity firm AhnLab Security Emergency Response Center (ASEC) said it's refraining from divulging more\r\nspecifics owing to the fact that \"the vulnerability has not been fully verified yet and a software patch has not been\r\nreleased.\"\r\nThe adversarial collective, after obtaining an initial foothold by an unknown method, abused the zero-day bug to\r\nperform lateral movement, shortly after which the AhnLab V3 anti-malware engine was disabled via a BYOVD\r\nattack.\r\nhttps://thehackernews.com/2023/03/lazarus-group-exploits-zero-day.html\r\nPage 1 of 3\n\nIt's worth noting here that the Bring Your Own Vulnerable Driver, aka BYOVD, technique has been repeatedly\r\nemployed by the Lazarus Group in recent months, as documented by both ESET and AhnLab in a series of reports\r\nlate last year.\r\nAmong other steps taken to conceal its malicious behavior include changing file names before deleting them and\r\nmodifying timestamps using an anti-forensic technique referred to as timestomping.\r\nThe attack ultimately paved the way for multiple backdoor payloads (Keys.dat and Settings.vwx) that are designed\r\nto connect to a remote command-and-control (C2) server and retrieve additional binaries and execute them in a\r\nfileless manner.\r\nThe development comes a week after ESET shed light on a new implant called WinorDLL64 that's deployed by\r\nthe notorious threat actor by means of a malware loader named Wslink.\r\nhttps://thehackernews.com/2023/03/lazarus-group-exploits-zero-day.html\r\nPage 2 of 3\n\n\"The Lazarus Group is researching the vulnerabilities of various other software and are constantly changing their\r\nTTPs by altering the way they disable security products and carry out anti-forensic techniques to interfere or delay\r\ndetection and analysis in order to infiltrate Korean institutions and companies,\" ASEC said.\r\nFound this article interesting?
