Attackers sent personalized fake federal court notices to more than 100,000 companies, impersonating the US District Court for the Southern District of Florida. The emails directed recipients to a counterfeit court website and offered a password-protected case file that ultimately installed LodaRAT, giving attackers a way to steal credentials, monitor activity, and remotely control Windows computers.
How the attack worked
The campaign impersonated the US District Court for the Southern District of Florida, sending personalized emails with a subject beginning "Court-Ordered ADR Notice" to more than 100,000 companies. Each message included the target's details and an ADR case ID, claiming the company was involved in an Alternative Dispute Resolution proceeding. Recipients were directed to a counterfeit portal at florida[.]courtadr[.]com that displayed their own company details and let visitors search for fabricated cases by ADR ID, reinforcing the illusion of a genuine legal matter.
A "Download Your Case File" link on the fake portal delivered a password-protected ZIP archive named after the recipient's ADR reference. Inside was an ISO disk image containing a .msc console file, a .bat batch script, and a .lnk Windows shortcut. These files worked together to download and run LodaRAT using legitimate Windows components, giving attackers a remote access trojan capable of stealing browser credentials and session cookies, logging keystrokes, capturing screenshots, and recording audio and webcam video.
Why it succeeded
The attack combined personalization with a convincing supporting website rather than relying on the email alone. By showing the target's own company name and a fabricated case ID on the portal, attackers created what amounts to an entire environment in which the alleged legal matter appears to exist. The legal and administrative framing added urgency and legitimacy, since unexpected court correspondence is the kind of message employees often feel compelled to act on quickly.
What to watch for
- Unexpected legal or court notices that reference a case ID and pressure a quick response.
- Links to external "court portals" rather than communication through verified channels.
- Password-protected archives, disk images, scripts, or shortcut files sent from outside the organization.
- Sender addresses that cannot be independently verified against known official court contacts.
How to build resistance
Organizations should treat unexpected court or legal correspondence as unverified until confirmed through independently obtained contact details rather than information in the message itself. A clear process for forwarding unexpected legal notices to Legal and Security teams helps ensure verification happens before any file is opened. Employees should never need to download an alleged case file to judge whether a notice is genuine. Security teams should also review how email and endpoint controls handle password-protected archives, disk images, scripts, and shortcuts from external sources, and awareness training should reinforce prompt reporting if a suspicious file has already been opened, so response can go beyond simply deleting the download.
