What Do Malicious Actors Do With Email Addresses?
Malicious actors use stolen email addresses to send spoof emails to phish users through malicious links and attachments. Downloading these attachments or clicking on the harmful links can install malware or ransomware on the user’s system. It enables the malicious actors to steal confidential data like financial information, passwords, and other critical data. Furthermore, they can encrypt the user’s information assets through ransomware, which they decrypt only after receiving the ransom.
How To Know If An Email Account Is Hacked?
Here are some signals to look for when you suspect that a threat actor may have compromised your customer’s email account.
- The user’s email password has been changed without their knowledge.
- The user receives emails in their inbox from people they do not recognize.
- Unexpected and unwanted emails keep arriving in the inbox.
- Different IP addresses keep showing up on the user’s log.
- User’s friends report receiving spam emails from their email addresses.
How To Remove An IP From The Gmail Blacklist?
Sometimes Gmail blocks a user’s emails. It is because they have blacklisted the IP address. The user can remove it from the blacklist by following these steps.
- Authenticate the email address using SPF, DKIM, and DMARC authentication methods.
- Submit the Gmail Blacklist Removal Form.
- Wait for Gmail to act on the removal request.
It could take a week to get an IP address removed from Gmail’s blacklist.
