What is Lip Ransomware?

Lip ransomware is a type of malware that encrypts all the files on a computer until the user pays a ransom. Files encrypted by Lip will have a .lip extension appended to the end of the file name. Lip is delivered through a Win32 EXE file and has been spotted inside the following files and processes: ['yyjol44qr.dll', 'buildz.exe'] Lip ransomware can query the cryptographic machine GUID, read ini files, download files from webservers via HTTP, and spawn processes. It can also perform DNS lookups and write files inside the user directory.

What is Ransomware?

Ransomware is malware that encrypts a user's files, making them unusable, and demands a ransom payment to restore access to the files. The "ransom" is often in the form of a cryptocurrency, typically bitcoins. The most common form of ransomware is cryptoviral extortion, where the attacker holds the victim's data hostage until a ransom is paid.

How Does ransomware Spread?

Ransomware is typically delivered via phishing emails, social engineering, exploit kits, or drive-by downloads. Once the ransomware is executed, it will encrypt files, append a file extension to the victim's files, and demand a ransom payment in exchange for the decryption key.

Lip Ransomware Capabilities

Lip ransomware is a type of malware that uses process injection attack techniques to evade process-based defences and possibly elevate privileges. By injecting code into processes, Iip ransomware may be able to access the process's memory, system/network resources, and elevated privileges. Lip ransomware may use a variety of application layer protocols to communicate with remote systems to avoid detection and network filtering. Commands and results may be embedded within the protocol traffic between the client and server, making it difficult to distinguish from normal traffic. 

This ransomware may also use protocols commonly used for web browsing, file transfer, email, or DNS. Lip ransomware uses System Information Discovery attack techniques to gather detailed system information about the target operating system and hardware. This information can be used to shape follow-on behaviours, including whether or not the adversary fully infects the target. Lip ransomware may also use the information from System Information Discovery during automated discovery to identify potential targets.

Mitigations Against Lip Ransomware:

• Lip ransomware can be mitigated by some endpoint security solutions that can be configured to block process injection. 
• Lip ransomware attacks can be mitigated by using network intrusion detection and prevention systems that use network signatures to identify traffic for specific adversary malware. 
• Lip ransomware attacks can be mitigated by using network intrusion detection and prevention systems that use network signatures to identify traffic for specific adversary malware.

How to Protect Against Ransomware?

The best way to protect yourself from ransomware is to keep your operating system and software up to date and patched, which will help prevent malware from infecting your computer. You should also back up your data regularly, so you won’t lose your important files if ransomware attacks your computer. Finally, you should be wary of email attachments and links from untrustworthy sources, and make sure you’re installing software only from reliable sources.

• Back up your data.
• Use secure file sharing. 
• Keep your software up to date. 
• Only download software from verified sources. 
• Use strong passwords. 
• Avoid suspicious links and emails. 
• Use antivirus software. 
• Use caution when opening email attachments.
