Different Types of Ransomware
Crypto and locker ransomware have historically been the two most common forms of malware. Threat actors have recently been interested in double extortion and ransomware as a service (RaaS).
Fremont, CA: Ransomware is among the most effective ways to target businesses, key infrastructure, and people. This malware infects computers and prevents users or external applications from accessing devices or entire systems until ransom demands get paid.
Let's look at the four forms of ransomware and examples of specific ransomware outbreaks and their impact on the security environment to comprehend the notion better.
• Locker ransomware
The Locker ransomware prevents users from accessing their computers. To enter systems, this version employs social engineering tactics and compromised credentials. Threat actors access the system and prevent users from using it until a ransom gets paid. On the victim's screen, a pop-up message may display, claiming, "Your computer was used to access websites that contained unlawful material. You must pay a $100 fee to unlock your computer," or "Your computer has got infected with a virus." To fix the problem, go here."
RaaS entails criminals renting access to a ransomware strain from the ransomware author, who sells it as a pay-per-use service. RaaS developers put their ransomware on dark websites and sell it as a subscription to criminals, similar to the SaaS model. The prices vary depending on the ransomware's sophistication and features, but there is usually a membership charge. A part of the ransom is given to the RaaS author under previously agreed-upon terms once members infect machines and collect ransom payments.
• Crypto ransomware
Ransomware that encrypts files is more frequent and ubiquitous than ransomware encrypts files. It encrypts all or partial files on a computer and demands a ransom in return for the decryption key from the victim. Some of the most recent varieties also infect shared, networked, and cloud storage. Malicious emails, websites, and downloads are how crypto-ransomware spreads.
• extortion ransomware
To blackmail victims into paying a ransom, double extortion ransomware encrypts files and exports data. Attackers that use double extortion ransomware threaten to reveal stolen data if its demands are not satisfied. It implies that the attacker still has control over the victim, even if they can recover their data from backup. On the other hand, paying the ransom does not ensure data security because the attackers have access to the stolen information.
