Compromised Email: What to Do When It’s Too Late

Has your corporate mailbox started sending spam? Did you notice emails moving to odd folders without your action? Or worse, did someone report that you sent messages with suspicious attachments?
If you experienced something like this, your email account may be compromised.
Unauthorized access to corporate email accounts ranks among the most underestimated—and harmful—cyber threats.

Signs Not to Ignore

An email account takeover is not always obvious at first. Sometimes everything seems fine until someone raises the alarm. A colleague may tell you they received strange emails from your address. Or you might spot missing messages that ended up in folders you didn’t create. More often, you detect the attack after the fact.

Typical warning signs of compromise include:

• Sudden, large-volume sends to unknown addresses
• Unusual settings in your email account
• Addition of unauthorized contacts
• Credential changes without your input
• Logins from unfamiliar IPs or countries

Contain the Attack

Like any illicit activity, an account takeover leaves traces. Spotting anomalies early can help you resolve the issue before it causes irreparable harm. Your first step is to block access to the compromised mailbox and regain control. Don’t stop at changing the password: an attacker may already hold keys to re-enter or stay hidden. Acting promptly limits damage, prevents clients from receiving dangerous messages, and protects your professional reputation.

Many believe only certain sectors face account takeovers. In reality, any organization can fall victim. These attacks rank among the most damaging cyber threats. Without proper prevention, they can hit not only financial outcomes but also damage the organization’s reputation and erode client trust.
