Password Change Request: “We’ve Detected Suspicious Activity on Your Account”. This message appears when a malicious program or attacker has successfully obtained your login credentials and accessed your account. From such compromised accounts, unsolicited messages and spam are typically sent.
What’s the solution?
Don’t wait—immediately change your account password using the form provided.
Frequently Asked Questions
I don’t want to enter my phone number. What should I do?
Providing your phone number is considered a necessary part of securing your account in this case.
A PIN code required to proceed with the form will also be sent to this number.
This phone number can later be used to recover your password if you lose access to your account.
How could someone obtain my login credentials?
The most common cause is reusing the same password and email on another online service.
Discussion forums, online services, shops, and mobile apps are popular sources of leaked credentials.
More on how to create and secure a strong password can be found in the article Secure Password for Your Account.
Do I really need to change my password?
Yes, changing your password is absolutely essential in this case. If spam continues to be sent from your account, it may lead to a permanent block of your Seznam account!
Important: Never return to your previous password. Doing so could allow the attacker to regain access.
More Details
What’s going on?
The password change request appears when our security systems detect unusually high message activity—or outright spam—being sent from your email account or through a connected mail program.
Mass distribution of unsolicited messages (spamming) harms other Seznam users and affects users across other services as well. It also damages the reputation of our mail servers.
In such cases, access to your mailbox is blocked for security reasons, and you are required to change your password. This prevents the malicious actor or program from continuing to send spam and blocks further access to your account.
Why did this happen?
A malicious program or attacker has discovered your login details and is now using your email account to send out spam, which must be stopped.
More information about secure passwords can be found in the article Secure Password for Your Account.
Alternatively, if you’ve knowingly sent a large number of messages to multiple recipients, this activity may have been flagged as suspicious or classified as unsolicited marketing communication.
What’s the solution?
Follow the instructions in the warning message exactly—change your password to something stronger (password strength must be at least “good”), and request a verification code to be sent to your phone number.
How can I prevent this in the future?
Start with the basics of internet safety:
- Avoid using the same email and password on multiple services.
- Don’t log in through untrusted or suspicious login forms.
- Always keep your antivirus software, firewall, and other security programs up to date.
If you regularly send large volumes of bulk or marketing emails, which may be considered unsolicited, we recommend reviewing the Emailing Code of Conduct, contacting our Sales Department about authorized bulk mailing, or using a specialized email marketing provider for such messages.
