How does Ransomware Work?

This malicious software has evolved over time, getting more efficient. The most recent evolution locks the computer display and does not allow the user to access any programs. This is done by dropping and executing a malicious binary on the infected system which then searches and encrypts valuable files. The ransomware may also exploit system and network vulnerabilities to spread to other systems and possibly across entire organizations.

Afterwards, the computer shows a message asking for a ransom to be paid within 24 to 38 hours to restore the encrypted files and the computer. Usually, the message claims to be from a branch of local law enforcement. To make the message more credible, logos are used. The people who are not aware of these scams or who just want to restore access to their computer pay a certain amount of money.

However, even if you pay the sum the computer’s functionality won’t be restored as the only way to do so is by removing the malware.
