What is ransomware?
The term "ransomware" is used for a type of malware that takes control of a victim's computer and encrypts its contents. Ransomware typically holds the system hostage by giving the user an hour or two to pay ransom to regain access before it destroys files.
How does ransomware spread?
This type of malware is often delivered through phishing campaigns, among other ways, and relies on social engineering to fool users into clicking. They also tend to be delivered via worm-laced spam messages, which can disseminate automatically via email or instant messaging without any intervention from the user.
About Pyphyfe ransomware
The ransomware Pyphyfe is a malicious program belonging to the Snatch ransomware family. It operates by encrypting data and demanding payment for the decryption. Victims of this scam are instructed to contact the cybercriminals with instructions on how to pay, an offer of free test decryption, and instructions on how to get their data back in exchange.
After encrypting your files, Pyphyfe will append all encrypted files with the .pyphyfe extension, and drop a ransom note onto your desktop titled 'HOW TO RESTORE YOUR FILES' in an attempt to pressure you into paying up to have your data restored to retrieve your personal data that you encrypted in the first place.
How to remove ransomware?
Various approaches can be taken in order to remove ransomware. Removing the malware may require a decrypting tool and application knowledge. The best approach would be to contact the cyber-security experts or system administrators of your computer in order to find a solution. You should also make use of antivirus software and antivirus exclusion rules, which allows you to exclude certain files from being scanned by antivirus software. Some other options for removing ransomware include using System Restore, Clear Memory, running "msconfig" through the Start menu, and uninstalling any previous versions of malware deleted before this infection.
How to protect against ransomware?
There are a few things to remember when dealing with ransomware. The first thing is not to open any emails or links that come in an email, particularly if it comes from someone you are unfamiliar with. This includes opening attachments as well. The second thing is to back up anything important and keep backups on an external hard drive or USB flash drive stored somewhere safe, preferably in a bank vault or safety deposit box (the interviewer may want to know where your backups are). Lastly, there should be more than one way of getting into your account to ensure that you can access the information even if something goes wrong.
