What sort of email scam is "Roundcube Account Errors"

What kind of email is "Roundcube Account Errors"?

We have examined this email and determined that it is a phishing scam. The message is disguised as a Roundcube webmail notification, falsely warning that the recipient's account has errors requiring immediate resolution. It is designed to drive recipients to a fake login page where their email credentials can be stolen, and it should be ignored.

"Roundcube Account Errors" email scam overview

The "Roundcube Account Errors" email arrives with a subject line referencing the recipient's address followed by "Please confirm to continue." The body, signed by "Round-Cube Notifications," warns that the recipient's mail account will stop sending and receiving messages on a specific date due to unresolved errors.

Recipients are urged to click a button labeled "RESOLVE ERRORS NOW." Doing so opens a page hosted on Google Cloud Storage infrastructure that has been repurposed to host a fake Roundcube Webmail login page.

The fraudulent page displays fields for a full email address and a password, along with a "Login" button. Any credentials entered there go directly to the scammers. With access to a victim's inbox, cybercriminals can read private messages, trigger password resets on linked services, and use the account to send further scam emails.

It should be noted that Roundcube is a legitimate, open-source webmail client with no connection to this scam. Cybercriminals abuse its branding to make the email look credible. Roundcube is not responsible for the misuse of its name in deceptive campaigns like this one.

Similar phishing spam campaigns

In summary, this email is a phishing scam disguised as a Roundcube webmail notification. Its goal is to capture the recipient's email credentials through a fake login page. Anyone who receives it should delete the message without following any of its links. In some cases, email scams like this are also used to spread malware.

How do spam campaigns infect computers?

Cybercriminals frequently use email to deliver malware, typically by attaching malicious files or including links to harmful websites. Attachments may be executable files, Office documents, PDFs, archives, or scripts. Interacting with these files, such as enabling malicious macro commands in a document, triggers the infection.

Links in spam emails can redirect to sites that download malware automatically or prompt the user to do so manually. In most cases, an infection requires the recipient to take a direct action, such as opening a file or running an installer. Staying cautious about any unsolicited email is one of the most effective defenses available.

How to avoid installation of malware?

Be skeptical of unexpected emails, particularly those claiming urgent account actions are needed. Avoid clicking links or opening attachments from unknown or unverified senders. Even messages that appear to come from familiar services should be verified through official channels first.

Download software and updates only from official websites and trusted app stores. Avoid pirated programs, key generators, or files from peer-to-peer networks, as these are common sources of malware. Keep your operating system and applications up to date to reduce the chance of exploitation.

Use a reputable antivirus tool and keep it current. If you have already opened a suspicious attachment, 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.

Frequently Asked Questions (FAQ)

Why did I receive this email?

Scammers distribute these messages in bulk, reaching large numbers of recipients at once. Email addresses are gathered through various means, including data breaches, fake login forms, and similar sources. These campaigns are generally not targeted at any specific individual.

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

If you entered your email login credentials, change that account's password immediately. Check whether the same password is used on any other accounts and update those as well. Contact the email provider's support team if you believe the account may have already been accessed without your permission.

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

It depends on the file type. Executable files can compromise a device as soon as they are run. Document formats such as PDFs or Word files generally require additional user interaction, like enabling macros, before any malicious code activates.

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

No. Simply reading or viewing an email does not result in infection. Malware requires direct interaction, such as opening an attachment or following a malicious link, in order to activate.

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

Yes. Combo Cleaner is capable of detecting and removing a wide range of malware. Running a full system scan helps ensure that even threats embedded deeper in the system are identified and eliminated.
