What is DirectX 12 download scam?
Microsoft DirectX is a collection of application programming interfaces in Windows that allow software (especially games) to work with the audio and video hardware installed on a computer. The latest DirectX version is DirectX 12, and it is available for download on the official Microsoft page (microsoft.com). It is known that there is a fake DirectX download website used to trick users into downloading and launching a malicious installer designed to install CryptBot. It is important to mention that this could be not the only fake DirectX download page used to distribute the aforementioned or some other malware.
This deceptive website offers to download not only DirectX 12 but also older versions such as DirectX 11, DirectX 10, DirectX 9 (and other versions). As mentioned in the introduction, this fake DirectX download website distributes a malicious program called CryptBot. It is a trojan capable of stealing credentials (usernames, email addresses, passwords used to log into accounts), cookies from web browsers and cryptocurrency wallets, collecting text files, and taking desktop screenshots. Therefore, cybercriminals can use CryptBot to steal email, social media, banking, gaming, and other accounts, and use them to make fraudulent purchases, transactions, spread CryptBot further or distribute other malware, send spam, steal identities, extract money or personal from other users, or for other purposes. Also, they can steal cryptocurrency wallets and use them to transfer cryptocurrency to specified wallets, collect text files and make screenshots and try to monetize them by using them to blackmail victims or do it in other ways. In conclusion, a fake DirectX installer downloaded from this (or another) deceptive website can lead to monetary loss and identity theft. Also, it is likely that victims would not be able to access a variety of personal accounts and encounter other problems related to online privacy, browsing safety.

It is popular among cybercriminals to distribute malware via fake installers. As a rule, these installers are disguised as installers for legitimate software or its components. The main difference between a real (legitimate) and fake installer is a website where it is available for download. Fake installers are promoted through unofficial, deceptive websites and never on the official pages. It is important to mention that users often end up on shady websites (like the download page for a fake DirectX 12 installer) unintentionally - they get opened through deceptive ads, other untrustworthy websites or by installed potentially unwanted applications (PUAs).
How did CryptBot infiltrate my computer?
As mentioned in the first paragraph, a fake DirectX download website is likely to be not the only website used to trick users into installing CryptBot or another malicious software on their computers. It is known that not so long ago, CryptBot was (and possibly still is) distributed using a fake installer for a VPN client called Inter VPN. It is common that cybercriminals use Peer-to-Peer networks (torrent clients, eMule), third-party downloaders, freeware download pages, free file hosting sites, and other channels of this kind to distribute malware too. They use those channels to trick users into downloading and opening malicious files by disguised as legitimate, regular.
How to avoid installation of malware?
Software and files should be downloaded from legitimate, official websites and via direct links. Unofficial websites, third-party downloaders, Peer-to-Peer networks, and other similar channels are not reliable sources for downloading files or programs. Email attachments and website links in irrelevant emails received from suspicious addresses should not be opened. It is common that recipients who open files downloaded via such emails install malware on their computers. Already installed programs must be updated and activated properly: they should be updated and activated using tools or functions that their official developers provide. Most often, various third-party, unofficial tools are malicious/bundled with malware. Another issue with 'cracking' tools (unofficial activation tools) is that it is not legal to bypass the activation of any licensed software using them. The operating system should be scanned for malicious programs and other threats regularly. It is advisable that scans would be performed using a reputable antivirus or anti-spyware software. 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.
