How Does Ransomware Infect a Computer?
As malware variants continue to evolve, ransomware is fast becoming the most dangerous threat of all times. Financial gain is the primary motivation behind ransomware attacks.
Unlike many other malware programs that allow cybercriminals to steal valuable data from victims, ransomware directly targets the victims, holding their computer files hostage (using encryption) for a ransom. In recent years, there is not only an increase in the number of ransomware attacks, but the level of sophistication in those ransomware attacks has also increased.
Even though ransomware is considered one of the most advanced malware programs, they have an inherent vulnerability — ransomware must establish a communication channel with its creator to initiate the process of encrypting the victim's computer. In the process of communicating with the hacker, most ransomware variants generate a signature on the network which can be detected.
Today, ransomware programs are more advanced and stealthy, with some recent variants operating quietly in the background without making a single call to the hacker. Some ransomware variants even remove the data recovery options by encrypting the mapped network drives, deleting files and system restoration points.
How Ransomware Spreads?
Ransomware infects a computer when a user downloads or runs ransomware-infected files. Attackers hide such files in a seemingly begin software, so it is advisable to practice safe computing habits.
Email is the most common way by which ransomware spreads. The Ransomware is usually disguised as an email attachment and sent to unwary users. If the user opens such email attachments, it can lead directly to an infection. Another way used by cybercriminals is hiding the ransomware links in a button or the body of the email.
When clicked, it then redirects the user to a malicious website that leads to an infection. Hence, it is advisable that you verify the authenticity of any file or email attachments from unknown sources, before opening it.
Hackers lure unwary users into downloading ransomware by hiding malicious ransomware codes within cracked versions of different software such as games, adult content, online game cheats, and many more.
