Frequently Asked Questions
Mimic Ransomware Technical Details
What is Mimic ransomware and how does it operate?
Mimic ransomware is a sophisticated malware strain that abuses Everything32.dll APIs for file encryption. It deletes shadow copies, terminates applications and services, and leverages legitimate tools like 7za.exe and Everything.exe to extract and execute its payload. It creates persistence, disables security features, and uses multi-threading for faster encryption, making analysis more challenging for security researchers.
How does Mimic ransomware use Everything32.dll and Everything APIs?
Mimic ransomware abuses Everything32.dll, a legitimate Windows filename search engine, by using its APIs to query and locate files for encryption. It specifically uses the Everything_SetSearchW function to search for targeted file extensions and filenames, enabling efficient identification of files to encrypt or avoid.
What are the main capabilities of Mimic ransomware?
Mimic ransomware can collect system information, create persistence via the RUN key, bypass User Account Control (UAC), disable Windows Defender and telemetry, activate anti-shutdown and anti-kill measures, unmount virtual drives, terminate processes and services, inhibit system recovery, and remove indicators. It also registers a hotkey (Ctrl + F1) to display status logs and uses a session key file to resume encryption if interrupted.
How does Mimic ransomware achieve persistence and evade detection?
Mimic ransomware achieves persistence by creating entries in the Windows RUN key, disabling Windows Defender and telemetry, and activating anti-shutdown and anti-kill measures. It also removes indicators and inhibits system recovery to evade detection and hinder remediation efforts.
What file extensions does Mimic ransomware target and how does it mark encrypted files?
Mimic ransomware searches for files to encrypt using Everything APIs and appends the .QUIETPLACE file extension to all encrypted files. It uses specific search queries to identify files for encryption or exclusion.
How does Mimic ransomware use multi-threading and session keys?
Mimic ransomware employs the CreateThread function to run multiple threads, enabling faster encryption and complicating analysis. It also drops a session key file (session.tmp) to allow the encryption process to resume if interrupted.
What similarities exist between Mimic ransomware and Conti ransomware?
Mimic ransomware shares code similarities with the Conti ransomware builder, particularly in the enumeration of encryption modes and the use of functions like GetIpNetTable for ARP cache reading and NetShareEnum for Windows share enumeration. These similarities suggest Mimic may be based on or inspired by leaked Conti code.
How does Mimic ransomware use legitimate tools in its attack chain?
Mimic ransomware leverages legitimate tools such as 7za.exe (7zip) for extracting payloads and Everything.exe/Everything32.dll for file searching. It also uses legitimate sdel binaries and disables Windows Defender to facilitate its attack.
What is the significance of the Everything64.dll file in Mimic ransomware attacks?
Everything64.dll is a password-protected archive dropped by Mimic ransomware. When extracted using 7za.exe, it contains the malicious payloads necessary for the ransomware's execution and encryption process.
How does Mimic ransomware enumerate network shares and ARP cache?
Mimic ransomware uses the GetIpNetTable function to read the ARP cache and identify IP addresses for targeting. It then employs the NetShareEnum function to enumerate all Windows shares on the discovered IP addresses, excluding certain ranges like 169.254 (APIPA).
What anti-analysis techniques does Mimic ransomware use?
Mimic ransomware uses multi-threading, anti-shutdown and anti-kill measures, and disables system recovery to hinder analysis and remediation. It also removes indicators and employs obfuscated configuration decryption using the NOT operation.
How does Mimic ransomware display its ransom note?
After encrypting files and appending the .QUIETPLACE extension, Mimic ransomware displays a ransom note to inform victims of the attack and demand payment for decryption.
What is the role of the session.tmp file in Mimic ransomware attacks?
The session.tmp file is a session key file dropped by Mimic ransomware. It allows the ransomware to continue the encryption process if it is interrupted, ensuring that the attack can resume without starting over.
How does Mimic ransomware use hotkeys during execution?
Mimic ransomware registers a hotkey (Ctrl + F1) using the RegisterHotKey API. Pressing this hotkey displays status logs of the ransomware's activities, which may aid attackers in monitoring the attack's progress.
What is the significance of the NOT operation in Mimic ransomware's configuration?
Mimic ransomware stores its configuration in an overlay, which is decrypted using the NOT operation. This obfuscation technique makes it harder for analysts to extract and interpret the ransomware's configuration data.
How does Mimic ransomware handle virtual drives and system sleep?
Mimic ransomware can unmount virtual drives and disable system sleep and shutdown features, ensuring that the encryption process is not interrupted and that all targeted files are accessible during the attack.
What is the impact of Mimic ransomware on business operations?
Mimic ransomware can cause significant business disruption by encrypting critical files, disabling recovery options, and demanding ransom payments. The use of advanced evasion and persistence techniques increases the risk of data loss, reputational damage, and financial consequences.
