Checkmate is a new ransomware infection that encrypts large volumes of office data and demands victims to pay 15,000 USD for its decryption. The virus uses secure algorithms to encipher important pieces of data (e.g., documents, tables, databases, photos, etc.). During this process, all affected files get visually changed with the .checkmate extension. For instance, a file named 1.xlsx will change to 1.xlsx.checkmate and reset its original icon to blank. As a result, the data will become no longer accessible. Lastly, developers create a text note called !CHECKMATE_DECRYPTION_README.txt to explain how files can be decrypted. The text note states how many files have been encrypted and what can be done to reclaim them. As mentioned above, extortionists require victims to pay an equivalent of 15,000 USD in Bitcoin to their crypto wallet address. Additionally, swindlers also offer to try free decryption - by sending 3 encrypted files (no more than 15 MB each) through the Telegram Messenger. They will afterwards supply the victim with free decrypted samples and provide the wallet address for the ransom payment. After transferring money, cybercriminals promise to respond back with decryption tools to unlock access to data. Unfortunately, at the moment of writing this article, there are no third-party tools that could allow free decryption without the direct help of cybercriminals. Means of encryption used by ransomware are usually very strong, making independent tools oftentimes useless with regard to decryption.

My Login Hub is a typical browser hijacker that claims to provide quick access to various e-mail accounts. Although it actually does, My Login Hub is considered a piece of unwanted software that should be removed. Upon its successful installation, users will see that the default address of the search engine, homepage, and new tab changes to hp.hmyloginhub.co. This address persists each time users boot up the browser, open a new tab, or enter some queries into the search bar. One of the main drawbacks making browser hijackers practically useless is often their inability to generate individual search results. The hp.hmyloginhub.co search engine used by My Login Hub is fake and instead powered by the legitimate Yahoo search. This means a newly entered search query will be redirected through hp.hmyloginhub.co, but eventually end up displayed by search.yahoo.com. In addition to this, researchers also point out on privacy risks associated with browser hijackers. Such software may surveil browser activity and collect important data like passwords, IP-addresses, or geolocations. This sensitive information may thereafter be sold to third-parties that could be potentially interested in it. To sum up, My Login Hub should be deleted from your browser and operating system as soon as possible because of doubtful features and security risks it may create.

Vkontakte DJ is a dubious desktop application that distributes itself under the name of a legitimate and popular Russian social media platform called "Vkontakte". A number of research groups classified it as a browser hijacker due to its features to change the browser homepage and search engine to yandex.ru without users' consent. On the initial basis, Vkontakte DJ positions itself as an application designed to help users download music and video without limitations. However, although such features may sound useful, their fulfillment may be poor and not bring the expected user experience. Users facing Vkontakte DJ on their PCs have also seen two more pieces of software installed in addition to it - "Yandex browser" and "Browser Manager". It is also likely you will see the icons of these programs pinned on the taskbar. Although the Yandex browser is legitimate, the company itself has a bad reputation for using intrusive methods of promoting its software.

Vkontakte DJ is not a virus, but should be viewed as an unwanted application if you received it without permission. In such a case, we advise you to remove the application and everything else related to it (e.g. "Yandex browser", "Browser Manager", etc.). Use our guide below to do it fast and without traces.
