More about ValleyFall

The ValleyFall malware exhibits a broad range of malicious functionalities that underscore its sophisticated nature and potentially devastating impact on infected systems. Among its notable features, keylogging stands out as a primary focus, allowing the malware to covertly capture keystrokes made by the victim.

This enables the malicious actors behind ValleyFall to acquire sensitive information, such as login credentials, personal data, and confidential communications. Beyond the functionalities previously discussed, this malware also illicitly acquires computer data. This encompasses information about the graphics hardware, disk and Random Access Memory (RAM) capacity, the installed Windows version, hardware specifications, and more.

Moreover, this malware incorporates the capability to retrieve a PE file upon receiving specific commands and execute it on the victim's system. This functionality opens up the potential for downloading and executing additional malware (e.g., ransomware or crypto-mining malware). This can lead to data encryption, system disruption, monetary loss, and other serious problems.

To evade detection and analysis, ValleyFall employs an intricate evasion tactic by scanning for virtualization processes. This approach is designed to thwart security measures and complicate efforts to dissect and mitigate the malware, underscoring the malware's commitment to remaining covert and elusive. ValleyFall can also evade security software.

In conclusion, ValleyFall is a highly sophisticated and multifaceted malware strain with the capacity to infiltrate and compromise targeted systems. Its extensive functionalities, including keylogging, data gathering, remote control, and evasion tactics, make it a potent tool for cybercriminals seeking to steal sensitive information and carry out covert operations.

How did ValleyFall infiltrate my computer?

Users can inadvertently infect their computers with ValleyFall by opening a deceptive file (a downloader) that disguises itself as something harmless, like an image. Once opened, it secretly downloads malicious files and uses tricks to hide its activities and stay on the victim's computer.

The downloader used to distribute ValleyFall may be propagated in various ways. Cybercriminals could send phishing emails with attachments that appear to be innocuous images. These emails may contain enticing subject lines or urgent messages to encourage recipients to open the attachment.

Also, users may unknowingly download such image files from compromised or malicious websites. These websites may trick users into clicking on links that initiate downloads without their consent. In some cases, visiting compromised or malicious websites can trigger drive-by downloads, where the image file is automatically downloaded to the user's computer without any action on their part.

Additionally, malicious actors can upload deceptive image files to file-sharing platforms, torrents, or peer-to-peer (P2P) networks. Unsuspecting users who download files from these sources may inadvertently get infected.

How to avoid installation of malware?

Download software and apps exclusively from trusted sources, such as official websites or reputable app stores like Google Play Store, Apple App Store, or Microsoft Store. Avoid downloading cracked or pirated software. Regularly update your operating system, web browsers, and other software applications.

Install reputable antivirus or anti-malware software and keep it up to date. Exercise caution when opening email attachments or clicking links, especially if emails are from unfamiliar senders or contain unexpected content. Refrain from downloading files from P2P networks and torrent sites. Do not trust ads and links on shady websites.

If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.
