STRRAT is a malicious program distributing through e-mail spam messages. Decoded, STRRAT refers to Remote Administration Trojan (RAT), which aims at hijacking sensitive data. The object of focus is usually hanging around login data saved in browsers or e-mail clients. A list of data usually includes banking credentials, passwords, history, IP addresses, and more personal intel representing the money value sought by the developers. STRRAT allows the extortionists standing behind to manage a PC of victims remotely. By doing so, they are able to read and sort out the information they need to extort. Web browsers like Google Chrome, Mozilla Firefox, Internet Explorer, and e-mail clients like Foxmail, Microsoft Outlook, and Mozilla Thunderbird can be easily tracked by the virus once it gets on the system. The stolen information can therefore be abused to perform illegitimate transactions and other fraudulent steps pursuing personal benefit. Technically, as STRRAT developers have access to affect your entire system, they are more than capable of installing other potentially dangerous software (e.g. ransomware, cryptocurrency mining programs, adware, browser hijackers, etc.).
Maql Ransomware is a disastrous virus, that uses AES encryption algorithms to encrypt users' files. After encoding files obtain following extensions: .maql. The malware aims at encryption of personal data, such as documents, photos, videos, music, e-mails. Deep encoding makes those files unapproachable and decryption instruments available today cannot help in most cases. To start automatically each time the OS starts, the cryptographer creates an entry in the Windows registry key that defines a list of programs that start when the computer is turned on or restarted. To determine which key to use for encryption, Maql Ransomware tries to establish a network connection with its command server. The virus sends information about the infected computer to the server and receives the encryption key from it. In addition, the command server can send additional commands and modules to the virus that will be executed on the victim's computer. If the data exchange with the command server was successful, the virus uses the received encryption key (online key). This key is unique for each infected computer. If Maql Ransomware was unable to establish a connection with its server, a fixed key (offline key) will be used to encrypt files.
The Graphics card plays a very important role - that is analyzing and displaying the picture to your monitor. Sometimes, there are troubles when Windows cannot identify whether a graphics card is installed on your motherboard. In other words, users cannot use it to run video games and other tasks during the process. Usually, computers are equipped with integrated cards alongside the processor to run simple tasks. Discrete ones get often enabled to increase maximum performance during gaming and editing experience. If one of them goes off, the system will switch up to another. This can slacken your PC and limit its capabilities to pull off the needed tasks. Luckily, experts have found and tested some methods that contributed to solving this issue thus far. See the step-by-step guide to revive your graphics card down below.
Being a successor of Kronos, Ares is another trojan designed to collect banking data. Trojans are programs, which force the download of other malware. In our case, Ares is meant to install a program-spy called Ares Stealer. Once it settles down your system, the trojan will be able to read and record sensitive data entered during the usage. The main target is usually passwords, credit/debit card numbers, usernames, e-mail, and other banking-related information used on various websites or desktop applications. The worst part is that some users might not know that they are surveilled. They continue using and entering confidential data, which leaks to servers of cybercriminals. All credentials and other types of private intel collected by swindlers can be abused to make online transactions, sell your personal details, and more. Overall, the most obvious sign of trojans infesting your system is unusual computer behavior.
Udacha is a ransomware virus that encrypts data with AES+RSA algorithms and demands payment of 490$ (0.013 BTC) in order to return it. This information is visible inside of the ReadMe_Instruction.mht file, which is created after encryption puts its finishing touches onto the data. Prior to this, however, users will see their files changed with the .udacha extension. To illustrate, a file like
1.pdfwill change to
1.pdf.udachaand reset its shortcut icon. Below, you can see the full information that is written within the ransom note.
Also known as Trojan:Win32/Wacatac, Wacatac is a trojan-type infection that is capable of doing truly irreversible damage. Trojans are generally the virus used to distribute other malicious software. When trojan gets on your computer, it forces so-called "chain installations". The amount of software that can be delivered may vary broadly, however, the most popular is Ransomware that encrypts files stored on your PC asking to pay a ransom as a result. Unfortunately, these infiltrations can lead to massive privacy loss by handing personal data to third parties for making a profit. IP addresses, passwords, credentials, and location are often the most valuable information that extortionists are looking for. Since the rise of Bitcoin, trojans also started distributing crypto mining software that mines cryptocurrencies without users' consent. These manipulations require a vast amount of system resources which can slow down the computer or even lead to the entire system collapse. Sometimes, trojans can contain adware and browser hijackers that disseminate deceptive ads and redirects. This can also lead to system infection that can put you in a meltdown.
