What is the Chuk ransomware?

Discovered by xiaopao, Chuk is a malicious program belonging to the Dharma ransomware family. Systems infected with this malware experience data encryption and users receive ransom demands for decryption.

During the encryption process, files are renamed following this pattern: original filename, unique ID assigned to the victims, cyber criminals' email address and the ".chuk" extension.

For example, a file originally named "1.jpg" would appear as something similar to "1.jpg.id-C279F237.[tchukopchu@tutanota.com].chuk", and so on for all affected files. After this process is complete, ransom messages are created in a pop-up window and the "FILES ENCRYPTED.txt" text file.

What is search.standartanalog.com?

search.standartanalog.com is a fake search engine. These bogus search tools are usually promoted by browser hijackers. Note that search.standartanalog.com is promoted by adware-type software with browser hijacker traits (e.g. ExtendedProcesser). Fake search engines typically have data tracking capabilities, and this extends to browser hijackers and adware.

Due to the dubious techniques used to proliferate this rogue software, it is also classified as a Potentially Unwanted Application (PUA). The apps that promote search.standartanalog.com have been observed being spread via fake Adobe Flash Player updaters/installers. This dubious distribution method is employed to proliferate Trojans, ransomware and other malware.

What is ExtendedProcesser?

ExtendedProcesser functions as a browser hijacker and adware. Depending on the browser, it changes certain browser settings to 0yrvtrh.com or search.standartanalog.com (the address of a fake search engine) and serves various advertisements. It can also access (collect) sensitive information.

Commonly, users download and install programs such as ExtendedProcesser unintentionally and, therefore, they are categorized as potentially unwanted applications (PUAs). Research shows that this particular app is distributed through a deceptive Adobe Flash Player installer.

What is xrclicks[.]xyz?

xrclicks[.]xyz displays dubious content or opens other untrusted websites. There are many pages similar to xrclicks[.]xyz including, for example, cachenews[.]biz, lastmedias[.]biz and vinphone[.]xyz. Commonly, they are opened by installed potentially unwanted applications (PUAs).

These apps often gather data and display advertisements. They are classified as PUAs, since users often download and install them inadvertently.

What is Hbdalna ransomware?

Discovered by GrujaRS, Hbdalna is a malicious program belonging to the Snatch ransomware family. Systems infected with Hbdalna ransomware have their data encrypted and users receive ransom demands for decryption tools/software. During the encryption process, all compromised files are appended with the ".hbdalna" extension.

For example, a file originally named "1.jpg" would appear as "1.jpg.hbdalna" following encryption. Once this process is complete, text files named "HOW TO RESTORE YOUR FILES.TXT" are dropped into affected folders. These files contain identical ransom messages.

What is "Activation Failed! (Error Code 001)"?

This is a typical technical support scam website used to deceive visitors into calling the provided number and paying for unnecessary services and/or software.

Generally, people do not visit these pages intentionally - they are opened through deceptive advertisements, other untrusted websites, or by installed potentially unwanted applications (PUAs). In any case, you should ignore these scam web pages.
