What is node Quota Exceeded email scam?

It is common that cybercriminals use email as a tool to trick recipients into providing personal information (like credit card details, name, surname, bank account number), installing malware on the operating system (e.g., ransomware, Trojan), transferring money. As a rule, they send emails purporting to be from a legitimate company, organization, or other entity. This particular email is disguised as a final notice letter from cPanel (web hosting control panel software developer) stating that a certain domain has reached its inode quota (a website has reached maximum allowed resources).

Inode Quota Exceeded email scam email spam campaign

Inodes contain information about the files, emails, directories, etc., stored on the server. Usually, the number of inodes is limited, and once its limit is reached, users cannot create or upload new files, receive emails, and their cPanel starts showing notifications informing that no temporary files can be stored on the account anymore. Scammers behind this email claim that a specific domain has reached its inode quota, their main goal is to trick recipients into opening the attached HTML file and entering information such as domain name, panel username, and password. They attempt to trick recipients into believing that by entering the required details, they will log into cPanel and automatically add more inodes to their hosting account. The attached HTML file sends entered information to a server controlled by cybercriminals behind this scam. Stolen information can be used to access hosting account and take control over the domain, download and modify files and use those modified files for a variety of illegal activities. Depending on the hijacked website, cybercriminals may have access to personally identifiable information, credit card data, and much more. It is important to mention that stolen login credentials for hosting platforms such as cPanel could be sold on the dark web as well.

How do spam campaigns infect computers?

When cybercriminals use email as a channel to deliver malware, they send attempt to trick recipients into opening a malicious email attachment or a file downloaded via a website link. Usually, they send emails pretending to be official, important letters from legitimate companies. Recipients infect their computers when they open a malicious Microsoft Office, PDF document, archive file (ZIP, RAR, or another), JavaScript file, executable file (like .exe). It is important to mention that documents opened with Microsoft Office 2010 or any other newer version infect computers only if users enable editing or content (macros commands). It is because the aforementioned versions have the "Protected View" mode, which prevents malicious documents from installing malware. However, older MS Office versions do not have this feature. Therefore, malicious documents opened with older versions install malware automatically.

How to avoid installation of malware?

Received irrelevant emails containing attachments or website links should be analyzed, especially when such emails are received from unknown, suspicious addresses. Quite often, emails from unknown senders that contain files or links are used to deliver malware. Software should not be downloaded or installed through third-party downloaders or installers. It is also not safe to use unofficial pages, Peer-to-Peer networks. free file hosting sites, and other sources of this kind for downloading files, programs. Files, programs should be downloaded from official websites and via direct links. Installed software has to be updated using tools, functions that the official developers provide. The same applies to software registration or activation. It is important to know that it is illegal to bypass activation of licensed using various unofficial, third-party tools. Also, both unofficial activation or updating tools tend to be malicious. One more way to keep computers safe is to scan them with a reputable antivirus or anti-spyware software regularly, and always keep that software up to date. If you've already opened malicious attachments, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer.
