Judicial Phish Delivers XWorm in Colombia

Last updated October 28, 2026

A real phishing campaign targeted Colombian organizations with Spanish-language messages posing as administrative or judicial correspondence. The emails used script attachments disguised as documents and pressured recipients to open them, ultimately delivering XWorm malware through hidden PowerShell and a reusable loader.

Key findings

  • Colombian organizations received Spanish-language phishing emails that urged prompt attention and mimicked judicial or administrative correspondence.
  • The malicious attachments were VBScript and JavaScript files named to look like documents, encouraging recipients to run scripts.
  • Opening the attachment led to concealed PowerShell activity and loading of a .NET component that delivered XWorm.
  • The same .NET loader was found in a separate UK-linked case, but the report says this demonstrates loader reuse rather than proving the same attacker.
  • The malware can collect system and user information and supports commands for downloads, shell execution, plugins, webcam capture, and other actions.

Who’s being targeted

  • Commonly targeted roles: Administrative staff, Legal and compliance teams, Public-sector employees, Executive assistants, Document-processing staff, All email users.
  • Affected industries: Government and public-sector organizations, Judicial and administrative organizations, Organizations in Colombia, Organizations in the United Kingdom.
  • Attack channels: email.
  • Impersonated: A Colombian judicial or administrative organization.

Awareness takeaways

  • Treat unexpected script attachments as dangerous, even when their file names appear to describe an official document or legal notice.
  • Do not let urgency override verification. Independently confirm unexpected judicial or administrative messages through a known contact channel before opening an attachment.
  • Check the real file type before opening an attachment; a .vbs or .js file is not a normal court, administrative, or business document.
  • Report suspicious document-themed emails promptly, because opening the attachment can trigger hidden malware delivery rather than display a document.

Red flags to watch for

  • The attachment is a VBScript or JavaScript file rather than a normal document.
  • The message creates urgency by asking for prompt attention.
  • A supposed official correspondence asks the recipient to execute a script.

A judicial notice lands in your inbox: urgent attention required. It looks like official Colombian correspondence. But the attachment isn't a document: it's a .vbs or .js script, named to look like a legal notice. That's the trick: opening it runs code, not a document. Hidden PowerShell loads a .NET component that delivers XWorm, which can collect information and run commands. Unexpected court notice with a .vbs or .js attachment? Report the email without opening it.
