While initially known in Russia, nowadays the term ransomware has grown widely all over the world. From millions to billions, hackers have taken huge amounts of ransom money from users who try to retrieve their data after being attacked by this malware.
It’s a type of computer malware that secretly installs on a computer system, executes itself to lock computer’s data and demands for a ransom amount to give the data back. It is, therefore, a type of Denial of Service (DOS) attack that prevents the victim from accessing his data without the decryption key.
Cryptoviral extortion, a 3-round protocol carried out between the attacker and the victim, goes as follows:
In Ransomware attacks, usually, payment is the goal. Victims are made to pay a ransom amount to get their data back. Therefore, a key element that helps attackers in carrying out such attacks successfully is a convenient payment system. From wire transfers to pre-paid vouchers, attackers use a wide range of methods for online payment.
Keeping both online and offline backups of data will help you recover easily from such attacks. Also, downloading anti ransomware tools and usage of web security software will help to keep such threats at bay. Not just individual internet users but businesses also need to care about these ransomware attacks in order to ensure safety of their data.
