Hackers release new variations every 3-4 days, and it is still hard to prevent the infection and recover from it. Recent versions have modified extensions, that are added to the end of affected files, now they are: .cosd. Although, there are decryption tools from Emsisoft available for previous versions newest ones are usually not decryptable. The penetration, infection, and encryption processes remain the same: spam malvertising campaigns, peer-to-peer downloads, user's inattentiveness, and lack of decent protection lead to a severe loss of data after encryption using strong AES-256 algorithms. After finishing its devastating activity Cosd Ransomware leaves the text file - a ransom note, called _readme.txt, from which we can learn, that decryption costs from $490 to $980 and it is impossible without a certain decryption key.

The Malwarebytes experts have classified Best Searcher as another browser hijacker, which manipulates browser settings in favor of various changes. To be more precise, it changes your homepage domain to mh.aatub.xyz and affects some visual adjustments to the start page of your browser. Whilst all of these changes are meant to improve the browsing experience, our investigation proves completely the opposite. Best Searcher does not generate unique results, instead, it might mimic the capabilities of legitimate search engines (Google, Yahoo, Bing, etc.) to show ostensibly better results. Using Best Searcher makes no sense as it also causes redirects to other suspicious pages, which contain dangerous content. A number of ads and banners being displayed along with the usage, can gobble up system resources and downgrade your system significantly. The last, but most important thing to mention is data-tracking abilities. Browser hijackers do not guarantee any privacy terms. This is why your data may be at risk of being spied by Best Searcher developers. If you suspect something is wrong with your browser, we recommend you get rid of the program causing the above-mentioned changes. Our guide below will show how to do this.
