What is ransomware?
Ransomware is a sort of malware (malicious software) employed by hackers. Suppose a machine or network has been attacked with ransomware. The ransomware disables access to the device and encrypts its data from access. Cybercriminals demand money or crypto coin from their victims in return for releasing the data. After an infection, victims of malware assaults have three options: pay the ransom, attempt to remove the software, or reset the device. Attack vectors typically utilized by extortion Trojans include the RDP, phishing emails, and software flaws. A ransomware attack may thus target both people and organizations.
In particular, two forms of ransomware are trendy:
Locker ransomware: This sort of virus inhibits robust computer functionality. For example, you may be refused entry to the desktop when the mouse and keyboard are partly disabled. This permits you to continue to interact with the window holding the ransom demand to make the payment. Apart from that, the PC is unusable. The Locker malware doesn’t target essential data; it only tries to lock you out. Destruction of your data is, thus, improbable.
Crypto Ransomware: Crypto-ransomware seeks to encrypt your vital data, such as papers, images, and movies, but not to interfere with crucial computer processes. This spreads fear since users can see their files but cannot read them. The attacker often add a countdown to their ransom money: “If you don’t pay the ransom by the deadline, the cybercriminal will remove all your files.” due to the large number of users who are uninformed of the need for alternative or backup in the cloud or on external physical disk drives, Crypto-ransomware can have a devastating impact. Consequently, many victims pay the ransom to get their data back.
Let’s check the well-known examples of ransomware.
❐ Locky Ransomware Attack
Locky is a type of ransomware attack that encrypts the victim’s files and demands a ransom payment in exchange for the decryption key.
