File-Locker Ransomware – Distribution
File-Locker ransomware infection occurs once the executable file named File-Locker Ransomware.exe is running on the system. The payload may be spread via different techniques, but one of them is considered to be the preferred one. It’s about spam email messages that generally deliver the ransomware payload. Such emails usually come with a spoofed sender and an email address. This trick aims to mislead addressee that the received email appears to be sent from a trustworthy source like favorite websites, popular services, public organizations and even governmental entities. The main aim of these emails is to trick receivers into reaching out a malicious file attachment or a corrupted web link. Once the malicious file attachment that carries the File-Locker ransomware payload is started on the system, it triggers the infection. Plagued email attachments usually come as documents, archives, pictures, projects, or other commonly used file types. When a corrupted web link is used for the ransomware distribution, it lands on a web page which has the payload injected into its code. As it may be set to download the malicious file automatically the ransomware penetrates the system unnoticeably and starts encoding target data.
File-Locker Ransomware – Infection Flow
It seems that the code of a threat created for educational purposes – HiddenTear has been modified for another severe ransomware attack and released in active attack campaigns against online users. The File-Locker is a new HiddenTear based ransomware that is targeting primarily users in Korea which does not exclude its distribution worldwide.
The analyses of the new File-Locker ransomware samples reveal that it can perform various malicious actions. Once the ransomware payload contained in the file File-Locker Ransomware.exe is running on the system, it initiates a sequence of malicious actions. Thus the threat could easily bypass the available security layers and establish its malicious files on the system. Additionally, File-Locker can create more malicious files and terminate various processes to fulfill the attack. Some files associated with File-Locker may be located in the following system folders:
- %AppData%
- %Temp%
- %Roaming%
- %Common%
- %System32%
File-Locker ransomware uses the AES encryption algorithm to encode a predefined list of target file extensions and then appends the extension .locked to all corrupted data. Afterward, it requests 50,000 Won, or approximately 50 USD, from victims so they could get the files back. The amount should be transferred in bitcoin to a specified Bitcoin address that supposedly belongs to the creators of the threat. The exact address is mentioned in a ransom note created on the desktop. It is called Warning!!!!!!.txt and is written in both English and Korean. What the entire note reads is:
한국어: 경고!!! 모든 문서, 사진, 데이테베이스 및 기타 중요한 파일이 암호화되었습니다!!
당신은 돈을 지불해야 합니다
비트코인 5만원을 fasfry2323@naver.com로 보내십시오 비트코인 지불코드: 1F1tAaz5x1HUXrCNLbtMDqcw6o5GNn4xqX 결제 사이트 https://www.localbitcoins.com/English: Warning!!! All your documents, photos, databases and other important personal files were encrypted!!
You have to pay for it.
Send fifty thousand won to fasfry2323@naver.com Bitcoin payment code: 1BoatSLRHtKNngkdXEeobR76b53LETtpyT Payment site https://www.localbitcoins.com/
Any contacts and negotiations with the hackers should be avoided. Remember that the ransom payment provides no guarantee of .locked files decryption. Following hackers’ rules only encourages them to continue spreading devastating infections like File-Locker ransomware and blackmail infected users. In this article are presented secure solutions that will help to regain the control over infected PC and corrupted files without funding crooks.
File-Locker Ransomware – Data Encryption
As File-Locker crypto virus script is HiddenTear based it utilizes the AES cipher algorithm to encrypt predefined file types. The ransomware scans the system for the following file extensions that store valuable information:
.txt, .doc, .docx, .xls, .index, .pdf, .zip, .rar, .css, .lnk, .xlsx, .ppt, .pptx, .odt, .jpg, .bmp, .png, .csv, .sql, .mdb, .sln, .php, .asp, .aspx, .html, .xml, .psd, .bk, .bat, .mp3, .mp4, .wav, .wma, .avi, .divx, .mkv, .mpeg, .wmv, .mov, .ogg, .java, .csv, .kdc, .dxg, .xlsm, .pps, .cpp, .odt, .php, .odc, .log, .exe, .cr2, .mpeg, .jpeg, .xqx, .dotx, .pps, .class, .jar, .psd, .pot, .cmd, .rtf, .csv, .php, .docm, .xlsm, .js, .wsf, .vbs, .ini, .jpeg, .gif, .7z, .dotx, .kdc, .odm, .xll, .xlt, .ps, .mpeg, .pem, .msg, .xls, .wav, .odp, .nef, .pmd, .r3d, .dll, .reg, .hwp, .7z, .p12, .pfx, .cs, .ico, .torrent, .c
Each time File-Locker detects a match during the scan it modifies the original code of the target file and renders it completely unusable. All encrypted files receive the specific extension .locked at the end of their names. Corrupted .locked files remain unusable until a proper solution is applied for their recovery.
To prevent one of the available data recovery options, the ransomware deletes all Shadow Volume Copies stored in the Windows Operating System.
