The is a dangerous virus release which is currently being deployed in a global attack campaign. At the moment the number of captured sample is very low which indicates that the threat may still be under development. No information is also available about the hacker group behind it, given the way it is designed they might be experienced enough in order to have created it from scratch. The fact that it has been launched through several distribution methods indicates that there is a strategy behind the release. Like other similar threats this one is also spread using the most popular malware spread tactics — phishing emails, browser hijackers and malware sites. If a large-scale infections are required then infected payloads and browser hijackers can be used. The virus samples can be uploaded to file-sharing networks as well.
The ransomware can be programmed to carry out a wide range of malicious actions, including the following:
- Boot Changes — The associated engine can be used to make system changes to the way the computer boots. This behavior will start the .xLckr Ransomware as soon as the operating system is loaded. In addition access to the recovery boot options will be disabled which makes most manual user removal guides non-working. In these cases the victims will need to use a quality anti-spyware solution.
- Security Software Bypass — The malware engine can locate any installed security services which can block the virus infection. The programs are identified by looking out for their signatures in the memory and files on the hard disk. Affected services include anti-virus programs, sandbox environments, firewalls and intrusion detection systems.
- Additional Payload Delivery — The made infections can be used to download other threats to the infected hosts: Trojans, hijackers and miners.
- Windows Registry Changes — The .xLckr Ransomware can modify existing values stored in the Windows Registry and also creates ones for itself. This can lead to very serious problems with the computer’s performance rendering it completely unusable. Loss of data and unexpected errors can also come up as the normal functioning of programs and services is disrupted.
Not only is this virus built on a modular framework that allows further components to be added in future campaigns, it also has an unique feature — the ability to remove duplicate files. This is the ransomware that has been confirmed to include such functionality. It uses a built-in list of target file extensions which are scanned for duplicate file names:
.txt, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .sqlite, .odt, .jpg, .jpeg, .bmp, .gif, .png, .csv, .sql, .mdb, .sln, .php, .asp, .aspx, .html, .xml, .psd, .xsd, .cpp, .c, .h, .hpp, .htm, .py, .reg, .rb, .pl, .zip, .rar, .tgz, .key, .jsp, .db, .sqlite3, .sqlitedb, .bat, .bak, .7z, .avi, .fla, .flv, .java, .mpeg, .pem, .wmv, .tar, .tgz, .tiff, .tif
When all components have finished running the actual file encryption process will occur. The .xLck extension is applied to all victim files. The ransomware note will be shown via a lockscreen instance which will block the normal interaction with the system until the threat is completely removed.
