More about the "Web App Security" scam email

This phishing email claims that the recipient's email account has been disconnected from sending and receiving messages. It urges the recipient to confirm whether the account is still active on the server to restore normal email functionality. The message instructs the recipient to reconfirm the account through a provided link (labeled "Re-confirm account").

It also states that the mailbox will return to normal after this confirmation process. The link in this email leads to a fake email account login website that imitates the recipient's provider (e.g., Gmail or Yahoo Mail). Fraudsters use this fraudulent website to deceive users into entering their email login credentials.

After the information is submitted, it can be used to hijack an email account. The compromised account may then be exploited to send scam messages, steal sensitive information from emails, spread malware, or carry out other harmful activities. Cybercriminals can also attempt to access other services such as social media, online banking, gaming, and various personal accounts.

As a result, victims may face consequences like identity theft, financial losses, damage to their reputation, and other serious issues.

Similar scam emails in general

Emails of this type are designed to trick users into revealing their login details through fake websites that often mimic legitimate services. Once scammers obtain this information, they can take over accounts and misuse them for various malicious activities. In some cases, scam emails can be used to spread malware.

How do spam campaigns infect computers?

Malware is frequently spread through emails that contain harmful attachments or links. When a recipient opens one of these files or follows the instructions, the malicious software can infiltrate a device. These attachments may be malicious executable files, Office documents, PDFs, compressed archives like ZIP or RAR, scripts, etc.

Emails can also include links to untrustworthy websites created specifically to deliver malware. In some cases, simply visiting such a page can trigger an automatic download without the user realizing it.

How to avoid installation of malware?

Keep your operating system and all applications up to date. Only download software from official websites or trusted app stores, and avoid using pirated programs, cracks, or key generators. Do not click on suspicious ads or links, especially on unreliable websites, and never allow notifications from questionable pages.

Be careful with unexpected or irrelevant emails and messages, particularly those from unknown senders, and avoid opening any included links or attachments unless you are sure they are safe.

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?

Phishing emails are usually distributed to many people at the same time. The email addresses are often collected from leaked databases, fake websites, or similar methods.

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

If login details are exposed, all related passwords should be updated. If financial or other sensitive information is affected, the user should quickly inform their bank, service providers, or relevant authorities.

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

Executable files (like .exe) can infect a system immediately when they are run. Document files, such as PDFs or Word files, are less risky because they do not automatically execute malware when opened. Generally, whether a system is infected depends on the file type and how the user interacts with it.

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

Simply opening or reading a fraudulent email is usually not harmful on its own. Malware can only infiltrate systems via links or attached files.

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

Combo Cleaner can identify and remove most malware. However, some more advanced threats may avoid detection by hiding in the system. That is why a full system scan is advised to ensure that advanced threats are eliminated.
