"WeTransfer" removal guide
What is "WeTransfer"?
"WeTransfer" is the title of a deceptive email, designed to spread the Kryptik trojan. However, it may also be used to spread other malicious programs as well. It is strongly advised against opening this letter, especially the links found therein - as that will trigger the installation of the aforementioned malware.
The text presented in "WeTransfer" email is brief and simply informs recipients that they have been sent a document concerning the unspecified company's profile and purchase/order details ("Our company profile as requested and Purchase Order.pdf"). The letter is not bogged down in details, thereby it does not play with extreme emotions (e.g. fear or happiness). However, users may be tricked into downloading the archived file under the aforementioned title - simply from confusion or curiosity. It is not uncommon for cyber criminals to mentioned and/or use legitimate services for their malicious purposes. Both WeTransfer and ownCloud are genuine services (file transfer and hosting respectively) - which are grievously misused by the individuals behind this spam campaign. At the time of research, the link in the "WeTransfer" email opened an ownCloud webpage, from which the file containing Kryptik trojan could be downloaded. This is a high-risk malware with a wide range of abilities, including (but not limited to): system and browser modification, control over connected hardware and data exfiltration. To summarize, Kryptik is likely to cause severe privacy issues, significant financial losses and even identity theft. To protect device and user safety, it is crucial to eliminate all malicious programs without delay.

Social engineering and scare tactics are usually employed to further deceptive/scam emails. These letters are typically disguised as "official", "important", "priority", "urgent" and so on. The subject matter varies drastically, the written content can be well-researched and detailed or sloppy and hastily put together. Hence, emails riddled with grammatical errors and spelling mistakes, as well as other inconsistencies - should call the legitimacy of the letter immediately into question. The only goal of this deceptive mail is to generate revenue at user expense. This purpose can be achieved via malware infections, by tricking recipients into revealing their personal details (e.g. information relating to identity, banking account or credit card details, etc.) or making monetary transactions (e.g. blackmail for existing or nonexistent compromising material, various fake fees or payments, etc.) and many other scamming techniques. Systems are infected through attached files or links, leading to to the download of such. "Your computer hacked!", "Christmas Party Email", "HARASSMENT COMPLAINT" are a few examples of emails, used to proliferate malware. The Kryptik malicious software, spread through "WeTransfer" email spam campaign, shares similarities with Emotet, TrickBot, Adwind and countless other trojans.

How to avoid installation of malware?
Suspect and/or irrelevant emails should not be opened, especially ones received from unknown senders (addresses). Any attached files (or links) found in suspicious letters - must never be opened, as they are a potential origin of an infection. It is highly recommended to use Microsoft Office versions released after 2010. The newer releases have "Protected View" mode, which prevents malicious macros from immediately initiating the infection process when the document is opened. Malicious content can also be downloaded from untrustworthy download channels, e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders. Therefore, only official and verified download sources should be used. Illegal activation ("cracking") tools and third party updaters can also cause infections; hence, programs should be activated and updated with tools/functions provided by legitimate developers. To ensure device integrity and by extension - user safety, it is paramount to have a reputable anti-virus/anti-spyware software installed and kept up-to-date. Furthermore, this software is to be used for regular system scans and removal of detected threats/issues. If you've already opened the file downloaded from the website accessed via "WeTransfer" email, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
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. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections, we recommend scanning it with Spyhunter for Windows.
