Description
Detected characters resembling Latin letters within an email's subject and/or body.
This could indicate an attempt to impersonate a well-known brand or impersonate someone's identity.
This could also be used as a method to evade text scanners and analyzers.
Attacker's Goals
Impersonate known legitimate brands or evade defenses, tricking recipients into clicking on malicious links or attachments.
Investigative actions
- Check the characters in the email address for any characters that might look slightly different.
- 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.
- Check the domain the email came from, and if this domain is recognized within the organization.
- 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.
