The “We detected unusual activity on your account” scam is a phishing email that claims suspicious behavior has been identified on the recipient’s account. The email presents itself as a security alert from a known service provider. It warns that unauthorized access attempts or abnormal sign-in activity were recorded and that immediate action is required. This warning is fabricated and is not issued by a legitimate company.
The email instructs the recipient to secure the account by clicking a provided link. The wording focuses on reviewing activity, confirming identity, or preventing account suspension. The link does not lead to the official website of the service mentioned in the email. Instead, it opens a fraudulent web page designed to look like a real login portal. The page may display a familiar logo, a short security message, and fields for entering login credentials.
When the recipient types in a username and password, the information is transmitted to the scammers. The page does not check account activity or apply any security measures. It exists only to capture login details. After submission, the site can show a generic confirmation message or redirect to a legitimate login page to reduce suspicion. By that point, the credentials are already collected.
The targeted information in the “We detected unusual activity on your account” scam depends on how the email is framed. It can focus on email accounts, banking platforms, payment services, or other online profiles. Access to any of these accounts allows scammers to view personal data, transaction records, stored contact information, or billing details. If the compromised account is an email account, it can be used to reset passwords for other services linked to that address.
Once attackers gain access, they can change account passwords and recovery settings to lock out the legitimate user. They may also perform unauthorized transactions, gather additional personal information, or send phishing emails from the compromised account. The unusual activity claim is used only to create urgency and push the recipient to interact with the fake login page. The scammers do not have insight into real account activity.

How to identify phishing emails
The “We detected unusual activity on your account” scam arrives as a security-themed email. The subject line contains the same warning or a close variation referring to suspicious activity. The sender’s name is written to appear as a support or security department. A closer look at the full sender address shows a domain that does not match the legitimate service being impersonated. This mismatch is a strong indicator of fraud.
The body of the email is focused only on the security alert. It states that unusual activity has been detected and that the recipient must verify the account to prevent restrictions. The message often mentions a short timeframe for action. It does not include specific details such as exact login times, device names, or geographic locations that legitimate providers normally include in real security notifications. The main feature is the link directing the user to verify the account.
The phishing page linked in the email mimics a login screen. The domain in the browser’s address bar is unrelated to the real service and can contain extra words or slight spelling changes. The page includes fields for entering login credentials and may repeat the unusual activity warning to maintain the illusion of legitimacy. It lacks the full navigation structure and verified security indicators found on official websites.
Another defining trait is the narrow focus on suspicious activity. The same warning appears in the subject line, body text, and action button. The email does not reference billing, subscription plans, or other account features. It remains centered on the unusual activity claim.
Legitimate providers notify users about security events through official account dashboards and established communication channels. They do not request login credentials through external links embedded in unsolicited emails. The combination of a suspicious activity warning, a mismatched sender domain, and a login page hosted on an unrelated site defines the “We detected unusual activity on your account” scam.
