What sort of email scam is "cPanel Disk Quota Exhausted"

What kind of email is "cPanel Disk Quota Exhausted"?

We have examined this email and determined it is a phishing scam disguised as an automated cPanel service alert. It falsely claims the recipient's email account has run out of storage space and that incoming mail is now blocked. The goal is to steal email login credentials through a fraudulent sign-in page. This email should be ignored.

"cPanel Disk Quota Exhausted" email scam overview

The email poses as an official alert from cPanel's service monitoring system. It warns that the email account has exhausted its allocated disk quota and that the mail delivery daemon is now blocked from writing new messages to the inbox. The recipient is urged to click a "Manage Email Disk Usage" button to resolve the issue.

Clicking that button leads to a phishing site at loginsecurde4-dpqom26teqv9.edgeone[.]dev. The page is designed to detect the victim's email service provider and display a matching fake login form. Gmail users, for example, are shown a "gmail Portal" asking for their email address and password.

Any credentials entered there go directly to the scammers. A stolen email account can be used to read private conversations, hijack accounts on other platforms linked to that address, and send further phishing messages to the victim's contacts.

It should be noted that cPanel, L.L.C. is not connected to this scam in any way. The email merely copies the company's branding and copyright notice to appear trustworthy.

Similar scam emails in general

In conclusion, this is a phishing email impersonating cPanel to harvest email login credentials through a fake sign-in portal. Recipients should avoid clicking any links it contains and delete the message.

How do spam campaigns infect computers?

Cybercriminals frequently distribute malware by attaching malicious files to emails or including links that lead to harmful downloads. These files can take many forms - executables, compressed archives, PDF documents, Microsoft Office files, and scripts.

Opening such files, or in some cases enabling embedded macro commands within them, triggers the malware installation. As a rule, malware will not activate unless the user takes some direct action, such as running an executable or enabling features that allow additional code to execute.

How to avoid installation of malware?

Be careful with emails from unfamiliar senders, especially those that urge you to act immediately. Avoid clicking links or opening attachments in messages you were not expecting, even if the email appears to come from a known service or platform.

Only download software and updates from official developer websites or verified app stores. Pirated programs, key generators, and software cracks are common delivery vehicles for malware.

Keep your operating system and applications up to date. Run a reputable security program and perform scans regularly. If you have already opened a suspicious attachment, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate 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.

Frequently Asked Questions (FAQ)

Why did I receive this email?

Scam emails like this are sent out in large batches, not aimed at specific individuals. Cybercriminals gather email addresses through data breaches, fake sign-up pages, and similar methods, then send the same message to thousands of recipients at once.

I have provided my personal information when tricked by this email, what should I do?

If you entered your email credentials on the fake login page, change the password immediately for that account and for any other service where the same password is used.

If other sensitive data was also disclosed, such as payment or identification details, contact the relevant institutions or authorities without delay.

I have downloaded and opened a malicious file attached to an email, is my computer infected?

It depends on the file type. Executable files typically compromise the system as soon as they are opened. Documents such as Word files or PDFs generally require additional interaction, such as enabling macros, before any malicious code can run.

I have read the email but did not open the attachment, is my computer infected?

No. Reading or viewing the email itself is harmless. Infection only happens when you click a malicious link, open an attached file, or otherwise interact with content in the message in a way that allows it to execute.

Will Combo Cleaner remove malware infections that were present in email attachment?

Yes, Combo Cleaner is designed to detect and eliminate the vast majority of known malware threats. Running a full system scan is still recommended, since sophisticated infections may sometimes be structured to evade detection and require a deeper pass to remove completely.
