What is a Ransomware and How to avoid Ransomware Attack ?

Ransomware is a type of malicious software that encrypts files using a public-key cryptography system. Attackers send the virus software through email attachments, malicious websites, or exploiting vulnerabilities in software. If the program runs on a computer, all files on that computer will be encrypted, and the victim will lose the ability to open or view the content of the encrypted files. After encrypting all files, the virus program will be deleted automatically, leaving no trace.

After a computer is infected with ransomware, a message will appear on the screen demanding a ransom payment in exchange for a decryption key that will unlock the encrypted files. The ransom is usually demanded in cryptocurrency, such as Bitcoin, which makes it difficult to trace the attacker.

Ransomware attacks can be devastating for individuals and organizations, causing the loss of critical data, disruption of operations, and financial losses. Prevention is key, and it’s important to take steps such as regularly backing up data, using anti-malware software, keeping software up to date, avoiding suspicious websites, using strong passwords, and being cautious about clicking on suspicious links or downloading files from unknown sources.

What are the things to do soon after Ransomware Attack?

Getting rid of ransomware can be a difficult process, as the malware is specifically designed to prevent victims from accessing their files or systems. Here are some general steps you can take to remove ransomware:

• Disconnect from the internet: As soon as you suspect that your computer has been infected with ransomware, disconnect it from the internet to prevent the malware from spreading and potentially encrypting more files.
• Use anti-malware software: Run a full system scan using reputable anti-malware software. Some popular options include Malwarebytes, Norton, and Kaspersky. The software should detect and remove any malicious files on your system.
• Restore from backups: If you have backed up your data regularly, you can restore your files from a previous backup. This will allow you to recover your data without paying the ransom.
• Use a ransomware decryption tool: Some ransomware strains have decryption tools available, which can help recover your files without paying the ransom. You can check online to see if a decryption tool is available for the specific ransomware that infected your computer.
• Consider paying the ransom: While it’s not recommended, some victims choose to pay the ransom to get their files back. However, this is not a guarantee that the attackers will provide a working decryption key, and it also funds criminal activity.

If your computer has been infected with ransomware, it’s important to act quickly and follow these steps to remove the malware and recover your files. To prevent future infections, make sure to keep your software up to date, use strong passwords, and be cautious when opening email attachments or clicking on links.
