How to identify scams like "iCloud Storage Full" fake message

What is "iCloud Storage Full" scam?

Its purpose is to lure recipients to fake websites that present fabricated alerts and misleading instructions designed to manipulate users into performing specific actions. Recipients are advised to disregard such emails and delete them immediately.

More about the "iCloud Storage Full" scam email

The deceptive email states that the recipient's cloud storage account has reached full capacity and can no longer back up important data such as photos, contacts, and documents. It warns that synchronization has been suspended due to insufficient space and that files may be at risk if no action is taken.

The message urges the recipient to upgrade to a larger storage plan (250 GB) to restore backup functionality and secure their data. The provided link (button labeled "Get 250 GB) is designed to open untrustworthy pages. These web pages present various misleading messages, mostly fake alerts/warnings.

They falsely state that a user's cloud storage is full, causing backups and syncing to stop. They warn that various files, such as photos and videos, are no longer being uploaded because the limit has been reached. In addition, they claim that the user's subscription has expired and threaten that stored data could be removed unless the plan is renewed.

The links on these pages include affiliate IDs, allowing scammers to earn commissions whenever someone registers, makes a purchase, or takes another action. Those pages often redirect users to legitimate products, including McAfee or XSHIELD. Legitimate companies do not rely on deceptive emails and fake sites to advertise their products or services.

Conclusion

This is a scam that uses fake storage warnings to pressure users into clicking malicious links. The linked pages display fake alerts and attempt to generate revenue through affiliate schemes. It should be ignored, and no links or offers associated with it should be trusted.

Here are examples of similar scams: "Cloud Files Are Scheduled For Permanent Deletion", "Cloud Storage Plan Has Been Paused", and "Cloud Account Scheduled For Deletion".

How do spam campaigns infect computers?

Malware is distributed via email when threat actors include malicious attachments. They use various file types, such as documents, compressed files, scripts, and executables. Once opened or after certain actions, such as enabling macros, these files can compromise the system.

Cybercriminals may also send links that lead to hijacked or fake websites. These pages can either trigger automatic downloads or trick users into manually downloading and running malicious software.

How to avoid installation of malware?

Applications should be downloaded only from official websites or trusted app stores, while pirated software, cracks, and key generators should be avoided. It is also essential to stay cautious with email attachments and links, particularly when messages are unexpected or come from unknown senders.

Interacting with pop-ups, ads, buttons, or other elements on suspicious websites should be avoided, as they may lead to harmful content. In addition, using up-to-date operating systems and software, along with regularly using reliable antivirus or anti-malware tools, reduces security risks.

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?

Fraudsters often send identical messages to large numbers of people simultaneously. They obtain email addresses from leaked databases, misleading websites, or other sources where user information has been collected or exposed.

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

If login credentials have been stolen, the passwords should be changed immediately. In cases where financial or personal information may have been compromised, it is important to inform the appropriate banks, service providers, or institutions, and contact authorities if necessary.

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

The likelihood of infection depends on the file type and how it is handled. Executable files can infect a system immediately once opened, while documents typically pose a threat only if users enable features such as macros.

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

Viewing an email does not compromise a device. Infections typically occur only after a user clicks a harmful link or opens a malicious attachment.

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

Combo Cleaner is capable of detecting and removing most known security threats. However, some advanced infections may be specifically designed to avoid detection. Because of this, performing a full system scan is recommended.
