Water Hydra

Also known aswater_hydra

Water Hydra, also known as DarkCasino, is a financially motivated threat actor described in the content as a cybercrime APT. It was first detected in 2021 and has been characterized as having evolved from an economically motivated group into an advanced persistent threat. The group has targeted financial market traders and organizations associated with banks, cryptocurrency platforms, trading services, gambling sites, and casinos. Reported campaigns used sophisticated zero-day attack chains, including exploitation of CVE-2024-21412, an Internet Shortcut Files / SmartScreen bypass vulnerability, to target financial traders and ultimately infect systems with the DarkMe trojan or RAT. Trend Micro reported that Water Hydra used internet shortcut files disguised as JPEG images, and later updated its January 2024 infection chain to execute a malicious MSI to streamline DarkMe delivery. The group previously leveraged the WinRAR zero-day CVE-2023-38831 before public disclosure to target stock traders with DarkMe, including seeding lures in forex trading forums and stock trading Telegram channels. The content consistently associates Water Hydra/DarkCasino with financially motivated operations and zero-day exploitation in trader-focused intrusion campaigns.
