Questions & Answers

Q: How do attackers initially gain access to a user's data?

Attackers send harmless emails to entice users to respond, gradually progressing to emails with links to legitimate websites, and gradually gathering information about the user's operating system.

Q: How does the malware evade detection by Windows Defender?

The malware is delivered as a password-protected PDF, which prevents Windows Defender from scanning the code. Additionally, it uses reputation-based scanning, which Windows Defender cannot effectively perform.

Q: What happens when the user runs the password-protected PDF?

Running the PDF executes code that captures data from the user's browsers, including login credentials and cookies. This information is then transferred to the attackers.

Users should change their passwords, log out of all browsers, and secure any sensitive accounts. Attackers may sell the captured data on the dark web, making it crucial to take immediate action.
