What is XCry ransomware? And how does it implement its attack?
XCry ransomware is a dangerous crypto virus that came out in the middle of January 2019. It uses a .xcry7684 extension in marking its encrypted files and demands ransom from victims in exchange for the recovery of the files.
The instant its payload file is installed in the system, XCry ransomware will implement a series of modifications in the system. It starts by importing the following Windows functions in KERNEL32.dll:
The aforementioned Windows functions help XCry ransomware in implementing its attack. Some of them are used to obtain information from the infected computer and use them to bypass any security programs installed in the system. While others are used to launch or repress system processes and modify entries in the Windows Registry allowing it to execute its attack automatically in every system boot. After these modifications, XCry ransomware will scan the system in search of its targeted files, some of which are files with the following extensions:
.7z, .bat, .c, .cpp, .cs, .css, .doc, .dpr, .h, .hpp, .html, .j, .jav, .java, .jpg, .js, .jsp , .lua, .pas, .php, .php4, .php5, .pl, .pm, .pod, .ppt, .py, .rar, .rb, .rtf, .t, .tar, .tar.gz .tcl, .txt, .vb, .xls, .xml, .zip
XCry ransomware uses the AES encryption algorithm in encrypting its targeted files. Once the encryption is completed, it appends the .xcry7684 extension to each one of the encrypted files. It then opens an HTML file named “HOW_TO_DECRYPT_FILES.html” which contains the following message:
“Your files have been encrypted.
To decrypt your files, follow instructions
Open your explorer, in the pathbar, enter %appdata%
Find the file encryption_key and send it to email:
Await payment instructions.”
How is the malicious payload of XCry ransomware distributed online?
The malicious payload of XCry ransomware is allegedly being distributed via malicious spam email campaigns. These emails are reported to contain a malicious file that has malicious scripts used to install XCry ransomware in a targeted computer. This file may be a document, PDF, ZIP, or executable file so you have to be careful in downloading attachments from your email no matter where the email came from. You should also refrain from downloading files from unreliable sources as cybercriminals also use such methods in distributing malicious threats like XCry ransomware.
