	"plain_text": "North Korean Hackers Are up to No Good Again\r\nBy Catalin Cimpanu\r\nPublished: 2018-04-27 · Archived: 2026-04-05 12:46:47 UTC\r\nFor a month leading up to today's historic meet between North and South Korea's presidents, a North Korean hacking group\r\nhas amplified operations and has targeted a wide variety of business sectors in at least 17 countries.\r\nThe purpose of this campaign was to infect organizations, perform reconnaissance, and steal sensitive data. Targeted\r\nindustries included critical infrastructure, entertainment, finance, healthcare, and telecommunications.\r\nThis overly aggressive campaign appears to be a new operation carried out by a group of hackers primarily known as\r\nLazarus Group, the ones responsible for the infamous Sony Studios hack in 2014. Other names for this group are Hidden\r\nCobra, the name US authorities are using to describe it, but also the Hastati Group, Group 77, or Labyrinth Chollima.\r\nhttps://www.bleepingcomputer.com/news/security/north-korean-hackers-are-up-to-no-good-again/\r\nPage 1 of 4\n\n0:00\r\nhttps://www.bleepingcomputer.com/news/security/north-korean-hackers-are-up-to-no-good-again/\r\nPage 2 of 4\n\nVisit Advertiser websiteGO TO PAGE\r\nThe group operates in bursts of hacking activity aimed at specific targets. Past operations include Operation Troy,\r\nBlockbuster, or Dark Seoul.\r\nOperation GhostSecret started last month\r\nThe most recent Lazarus Group operation is codenamed Operation GhostSecret and appears to have started in mid-March\r\n2018 with attacks targeting the Turkish financial sector.\r\nCybersecurity firm McAfee describes this particular campaign as sophisticated due to the \"significant capabilities,\r\ndemonstrated by their tools development and the pace at which [the attackers] operate.\"\r\nResearchers identified malware with shared capabilities to hacking tools used in the 2014 Sony hack, but they also found\r\nnewer tools such as Bankshot (implant), Proxysvc (downloader), and Escad (backdoor).\r\nAttacks amplify in scale following public disclosure\r\nExperts noted that despite exposing the first attacks on the Turkish financial sector, the group continued its attacks unphased\r\nby the attention their tools and hacking infrastructure were getting.\r\nFurthermore, attacks seem to have ramped up, most likely in an attempt to use hacking tools while they were still effective\r\nand before security software would be able to detect them.\r\nMcAfee said it alerted the Thai government that some of the command and control servers used for Operation GhostSecret\r\nwere hosted on the compromised servers of Thammasat University in Bangkok. ThaiCERT seized and shut down the servers\r\ntwo days ago.\r\nA full and detailed report on Operation GhostSecret, including IoCs, is available here.\r\nAutomated Pentesting Covers Only 1 of 6 Surfaces.\r\nhttps://www.bleepingcomputer.com/news/security/north-korean-hackers-are-up-to-no-good-again/\r\nPage 3 of 4\n\nAutomated pentesting proves the path exists. BAS proves whether your controls stop it. Most teams run one without the\r\nother.\r\nThis whitepaper maps six validation surfaces, shows where coverage ends, and provides practitioners with three diagnostic\r\nquestions for any tool evaluation.\r\nSource: https://www.bleepingcomputer.com/news/security/north-korean-hackers-are-up-to-no-good-again/\r\nhttps://www.bleepingcomputer.com/news/security/north-korean-hackers-are-up-to-no-good-again/\r\nPage 4 of 4",
