Kryptik virus removal guide

What is Kryptik?

Kryptik (also known as Win32/Kryptik.BGIS) is a backdoor trojan which gets installed without user's knowledge. In other words, people do not install programs of this type on purpose. When installed, Kryptik can be controlled remotely. Basically, cyber criminals try to trick people into installing Kryptik so they could steal various information and then use it to generate revenue. If there is any reason to believe that Kryptik is installed on the operating system, then it should be removed as soon as possible. It is also worth mentioning that the term "Kryptik" (also known as Krypt, Cryptic, Crypt, Packed) is used by a variety of malware databases to describe "packed" files. In other words, the file is compressed.

Kryptik malware

Research shows that cyber criminals use Kryptik to steal information such as email addresses, clipboard data, usernames and passwords of various applications (and services) such as BancLine, Fidelity, CruiseNet, BankMan, Teller Plus and so on. Such information could be used to extract or steal money from victims, or other people, or at least cause various privacy issues. Additionally, Kryptik can steal digital certificates and their passwords, URLs of visited websites (and sensitive details from pages visited/used by a victim), POP3 and IMAP account information, computer name and username, version of the operating system and Outlook Express account data. One way or another, cyber criminals store all stolen data on a remote machine. Additionally, Kryptik trojan can generate various URL addresses, open random TCP and UDP ports, monitor and modify network traffic, change homepages on browsers, set up a proxy server, deny access to certain websites and so on. Furthermore, cyber criminals can use Kryptik to capture screenshots, record keystrokes, shut down or restart the infected computer and run executable files on it. The keylogging feature can cause serious problems, it means that this trojan can be used to record the keys struck on a keyboard, including credentials (logins, passwords) of important accounts such as banking, email and so on. Having these accounts stolen might cause financial, data loss and other problems. Captured screenshots could be used to blackmail victims by threatening them to spread some personal information or compromising material. The list of Kryptik'a capabilities is quite impressive, which means it could be used to cause a variety of problems. To avoid any of that we recommend to make sure that this trojan is not installed on the operating system, and if it is, then to remove it immediately.

The Internet is full of trojan-type programs, here are a few examples: Varenyky, GozNym and Extenbro. Some of them are really powerful tools, some of them not. However, in most cases cyber criminals use malicious programs of this type to steal sensitive information, infect computers with other high-risk malware (like ransomware) and so on. There is always a possibility that a trojans like Kryptik might cause serious and irreversible damage.

How did Kryptik infiltrate my computer?

It is unknown how cyber criminals spread Kryptik, however, there are few ways that most of them use. For example, spam email campaigns, fake software updaters, untrustworthy software download sources and unofficial software activation tools. Spam campaigns are used to spread infections through files attached to emails. Typically, these attachments are Microsoft Office documents, archive files (like ZIP, RAR), PDF documents, executable files (like .exe), JavaScript files and so on. If opened, these attachments infect computers with some high-risk malware. Fake software updaters cause damage to systems by downloading and installing malicious programs instead of updating the installed ones, or by exploiting bugs, flaws of the software that is not updated. Free file hosting, freeware download websites, Peer-to-Peer networks (like torrent clients, eMule etc.), third party software downloaders and other similar channels can be used to disguise malicious files as normal and harmless. When downloaded and opened, they install malicious programs. Software 'cracking' tools supposed to allow their users to activate installed (and paid) programs for free. However, instead of activation they often install malware as well.

How to avoid installation of malware?

If some received email is irrelevant, sent from unknown address and contains attachment, then we recommend to keep the attached file unopened. All programs should be downloaded using direct download links and official websites. We do not recommend to use any third party downloaders or any other channels that we mentioned in the paragraph above. Installed software has to be updated through tools or implemented functions that are designed (provided) by official software developers. Same applies to activation of paid software. Note, it is not legal to use 'cracked' software or 'crack' it with third party tools. We also recommend to have a reputable anti-virus or anti-spyware software installed and perform system scans periodically. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.
