Description

A URL shortener was detected in the email body.

Attacker's Goals

Attackers use URL shorteners to hide the true destination of a link, making it easier to trick recipients into clicking on it.

Investigative actions

  • Examine the sender's IP address and reputation.
  • Verify whether the sender's IP address has appeared in different log sources before, and if it is recognizable.
  • If the message contains attachments/links, scrutinize them for any suspicious indications.
  • Monitor further actions taken, such as file downloads or access to potentially malicious links.
