What is the "Unauthorized Login Attempt" email scam

What kind of email is "Unauthorized Login Attempt"?

We have inspected this email and determined that it is a phishing scam. The message poses as a security alert from a generic email service, falsely claiming that an unauthorized login was detected on the recipient's account. It is designed to trick unsuspecting users into entering their email credentials on a fraudulent website. This email should be ignored to prevent account compromise.

"Unauthorized Login Attempt" email scam in detail

The email carries the subject "[URGENT] Security Alert: Unauthorized Login Detected" and claims to originate from an "IT Security & Operations Team." It warns the recipient that an unauthorized login from an unrecognized IP address was detected and that mailbox access has been temporarily restricted.

To restore full access, recipients are told to click a button labeled "Verify Account Identity" within 24 hours. The email threatens that failing to do so will result in the account being permanently deactivated.

Clicking the button leads to a fake login page hosted on an IPFS gateway. The page presents a webmail login form styled to resemble Gmail, requesting an email address and password.

The site appears designed to adapt to whichever email provider the recipient uses. A Gmail user would see a Gmail-branded interface, while users of other services may encounter a version tailored to their provider, making the deception more convincing.

Anything typed into that form is captured by the scammers. With stolen email credentials, cybercriminals can take over the account, reset passwords for linked services, read private correspondence, and use the hijacked inbox to target the victim's contacts with further scams.

"Secure Mail Services" is a fictitious sender name. No legitimate company or email provider has any connection to this scam.

Similar scam emails in general

In summary, this is a phishing email disguised as an urgent security notice. It directs recipients to a fake login page to steal email account credentials. Scam emails of this kind are sometimes also used to distribute malware. Ignoring the message and avoiding any links it contains is the safest course of action.

More examples of similar scam emails are Weekend Security Maintenance, cPanel Disk Quota Exhausted, and Avis De Virement – Chorus Pro.

How do spam campaigns infect computers?

Spam emails can carry malware through file attachments or embedded links. Attachments commonly take the form of executable files, Office documents, archives such as ZIP or RAR, PDF files, or script files. Opening them can trigger a malware infection, particularly when the user enables malicious macro commands within an Office document.

Links in spam emails may also lead to sites that download malware automatically or persuade users into downloading and running harmful files manually. In either case, some form of user interaction is typically required before a system is compromised.

How to avoid installation of malware?

Treat unexpected emails - especially those urging immediate action - with caution. If a message claims to be from a service you use, log in through that service's official website directly rather than clicking any link in the email. Consider enabling two-factor authentication on important accounts for an added layer of protection.

Download software only from official developer websites or verified app stores. Avoid pirated content, key generators, and cracking tools, as these are frequently bundled with malware. Keep your operating system and installed applications updated to reduce the risk of exploitation.

Use reputable antivirus software and do not allow unfamiliar websites to send browser notifications. If you have already opened a suspicious file, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate any infiltrated malware.

Types of malicious emails:

Phishing Emails

Most commonly, cybercriminals use deceptive emails to trick Internet users into giving away their sensitive private information, for example, login information for various online services, email accounts, or online banking information.

Such attacks are called phishing. In a phishing attack, cybercriminals usually send an email message with some popular service logo (for example, Microsoft, DHL, Amazon, Netflix), create urgency (wrong shipping address, expired password, etc.), and place a link which they hope their potential victims will click on.

After clicking the link presented in such email message, victims are redirected to a fake website that looks identical or extremely similar to the original one. Victims are then asked to enter their password, credit card details, or some other information that gets stolen by cybercriminals.

Emails with Malicious Attachments

Another popular attack vector is email spam with malicious attachments that infect users' computers with malware. Malicious attachments usually carry trojans that are capable of stealing passwords, banking information, and other sensitive information.

In such attacks, cybercriminals' main goal is to trick their potential victims into opening an infected email attachment. To achieve this goal, email messages usually talk about recently received invoices, faxes, or voice messages.

If a potential victim falls for the lure and opens the attachment, their computers get infected, and cybercriminals can collect a lot of sensitive information.

While it's a more complicated method to steal personal information (spam filters and antivirus programs usually detect such attempts), if successful, cybercriminals can get a much wider array of data and can collect information for a long period of time.

Sextortion Emails

This is a type of phishing. In this case, users receive an email claiming that a cybercriminal could access the webcam of the potential victim and has a video recording of one's masturbation.

To get rid of the video, victims are asked to pay a ransom (usually using Bitcoin or another cryptocurrency). Nevertheless, all of these claims are false - users who receive such emails should ignore and delete them.

How to spot a malicious email?

While cyber criminals try to make their lure emails look trustworthy, here are some things that you should look for when trying to spot a phishing email:

• Check the sender's ("from") email address: Hover your mouse over the "from" address and check if it's legitimate. For example, if you received an email from Microsoft, be sure to check if the email address is @microsoft.com and not something suspicious like @m1crosoft.com, @microsfot.com, @account-security-noreply.com, etc.
• Check for generic greetings: If the greeting in the email is "Dear user", "Dear @youremail.com", "Dear valued customer", this should raise suspiciousness. Most commonly, companies call you by your name. Lack of this information could signal a phishing attempt.
• Check the links in the email: Hover your mouse over the link presented in the email, if the link that appears seems suspicious, don't click it. For example, if you received an email from Microsoft and the link in the email shows that it will go to firebasestorage.googleapis.com/v0... you shouldn't trust it. It's best not to click any links in the emails but to visit the company website that sent you the email in the first place.
• Don't blindly trust email attachments: Most commonly, legitimate companies will ask you to log in to their website and to view any documents there; if you received an email with an attachment, it's a good idea to scan it with an antivirus application. Infected email attachments are a common attack vector used by cybercriminals.

To minimise the risk of opening phishing and malicious emails we recommend using Combo Cleaner Antivirus for Windows. 

Example of a spam email:

What to do if you fell for an email scam?

• If you clicked on a link in a phishing email and entered your password - be sure to change your password as soon as possible. Usually, cybercriminals collect stolen credentials and then sell them to other groups that use them for malicious purposes. If you change your password in a timely manner, there's a chance that criminals won't have enough time to do any damage.
• If you entered your credit card information - contact your bank as soon as possible and explain the situation. There's a good chance that you will need to cancel your compromised credit card and get a new one.
• If you see any signs of identity theft - you should immediately contact the Federal Trade Commission. This institution will collect information about your situation and create a personal recovery plan.
• If you opened a malicious attachment - your computer is probably infected, you should scan it with a reputable antivirus application. For this purpose, we recommend using  Combo Cleaner Antivirus for Windows.
• Help other Internet users - report phishing emails to Anti-Phishing Working Group, FBI’s Internet Crime Complaint Center, National Fraud Information Center and U.S. Department of Justice.
