PlushDaemon makes use of a customized backdoor that we monitor as SlowStepper, and its essential preliminary entry method is to hijack official updates by redirecting visitors to attacker-controlled servers by a community implant that we name EdgeStepper. Moreover, we have now noticed the group gaining entry through vulnerabilities in internet servers, and in 2023 it carried out a supply-chain assault.<\/p>\n<h2>Overview<\/h2>\n<p>In 2024, whereas researching PlushDaemon\u2019s clusters of exercise (together with the <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/www.welivesecurity.com\/en\/eset-research\/plushdaemon-compromises-supply-chain-korean-vpn-service\/\" target=\"_blank\" rel=\"noopener\">supply-chain compromise of a South Korean VPN service<\/a>), we observed that an ELF file submitted to VirusTotal contained two subdomains from PlushDaemon\u2019s infrastructure.
