What is Ransomware?
Ransomware is malicious software used to demonstrate an online or offline, public or private system or data and demands a ransom payment. This ransom demand is typically paid in an encrypted, anonymous form of e-money, like Bitcoins.
A typical ransom message will claim that the person whose message you are seeing has accessed your system and files and has encrypted them with a sophisticated encryption algorithm. The ransom message will usually provide you with an email address to contact the attacker (and ostensibly decrypt your system) or give you some other method of proceeding to pay for the decryption key.
How Does Ransomware Spread?
Ransomware spreads by a variety of means. Crooks can use a Trojan to infect a system and silently send ransomware to all targeted email addresses in the compromised network. They will then sit back while victims automatically pay the ransom while watching their funds being transferred into an account that the criminal controls.
They can also connect directly to each other, sending ransomware from one device to another or add ransomware payloads onto other malware payloads. It may even spread through corrupting legitimate software from trusted sources, such as an update for popular games or applications from non-malicious sources.
How Does L30 Ransomware Work?
The ransomware will infect the system after downloading the malicious code from its Command and Control (C&C) servers. The C&C might be located on a legitimate website, such as Google Docs or Dropbox. Once the malicious file downloads, it will drop a copy to %TEMP% and run a batch file containing PowerShell commands to run and execute the malicious program. On execution, it will create a copy of itself and store it in %TEMP%. It will then encrypt files and identify encrypted files that are already encrypted by other attacks, such as the notorious “Rocker” malware.
The L30 Ransomware can target Windows XP, Windows Vista, Windows 7, Windows 8, and Windows 10. It will also spread successfully on Android.
How to Remove L30 Ransomware
An antivirus program can do the remove L30 Ransomware. There are also recovery tools that can be used in removing L30 Ransomware from the system. One such recovery tool is Data Restore PRO, which can recover data from hard drives and removable media, including USB drives and memory cards.
How to Protect My Computer From Ransomware

- Avoid downloading software from unverified sources.
- Always use up-to-date software and software patches.
- Avoid connecting to public networks unless necessary.
- Do not open attachments from suspicious sources.
- Install anti-virus software on the system.
