What is the "Email Deliverability Issues" email scam

What kind of email is "Email Deliverability Issues"?

After examining this email, we determined it is a phishing scam. The message poses as an alert from an entity called "Email Services," falsely claiming the recipient's account has deliverability problems that require immediate attention. Its purpose is to direct victims to a fraudulent website and steal their email login credentials. This email should be ignored.

"Email Deliverability Issues" scam email overview

The email arrives under the subject "Please confirm to continue." and presents itself as an urgent notification from a supposed service called "Email Services." It claims the recipient's email account is experiencing deliverability issues that need to be resolved right away.

The message urges the recipient to click a button labeled "Enable Deliverability Protection." No technical specifics are provided - the vague warning is designed to create a sense of urgency and prompt a hasty response without further thought.

The button in the email leads to a website that was imitating an email service provider's login page. Although the site is no longer active, it was built to collect the email account credentials of visitors who believed the warning was genuine.

Anyone who entered their login details on that page handed their email account directly to the scammers. With that access, criminals can read private messages, impersonate the account owner, reset passwords on linked services, and use the account to send further phishing emails to the victim's contacts.

It is worth noting that "Email Services" is not a real company. The name is a fabricated sender identity with no connection to any legitimate email service provider.

Email scams in general

In conclusion, this is a phishing email disguised as a routine account notification from an email service provider. It attempts to trick recipients into visiting a fake login page and surrendering their email credentials. The email should be deleted without following any of the instructions it contains.

Also, scam campaigns of this kind are sometimes used to distribute malware. In such cases, the email may carry a malicious file attachment or a link that downloads harmful software to the victim's device.

More examples of similar scam emails are Attached Files Sizes Exceeded Mail Quota Settings, Outgoing Messages Not Reaching Recipients, and Purchase Order Review Request.

How do spam campaigns infect computers?

Cybercriminals often distribute malware through email by attaching malicious files or embedding links to harmful websites. The files can take many forms - executables, Office documents, archives, PDFs, or scripts. Opening them, or enabling features like malicious macro commands, can trigger malware installation on the device.

In some cases, simply visiting a linked page is enough to start an automatic download. More commonly, the infection requires the user to open a downloaded file or run a program. Either way, some form of interaction with the malicious content is typically what allows the malware to take hold.

How to avoid installation of malware?

Treat any unsolicited email with caution, especially when it includes attachments or presses you to follow a link. If the sender is unfamiliar or the message feels out of place, avoid interacting with its contents altogether.

Download software only from official websites and verified app stores. Avoid pirated content, key generators, and unofficial activation tools - these are among the most common vehicles used to deliver malware to unsuspecting users.

Keep your operating system and all installed software up to date, and use a reputable antivirus or anti-malware program. 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.

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?

These emails are sent in bulk to thousands of addresses at once. Scammers compile address lists through data breaches, fake sign-up pages, and other similar methods. Receiving one does not mean you were specifically targeted.

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

If you entered your email credentials on the linked page, change that password right away and update it on any other account where you reuse the same one. Review your account's security settings and enable two-factor authentication if it is available.

If you also provided sensitive data such as credit card numbers or identification details, contact the relevant institution or authorities as soon as possible.

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

Executable files typically compromise a device as soon as they are launched. Files in other formats, such as Office documents or PDFs, generally require additional user interaction - for example enabling macros or running a bundled installer - before malware can activate.

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

Simply reading an email does not put your computer at risk. Infection requires actively interacting with a malicious attachment or link. If you only read the message without clicking anything, your device is safe.

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

Yes, Combo Cleaner can detect and remove a wide range of malware. Running a full system scan is important to ensure all threats are found and eliminated, including any that may be hiding deeper in the system.
