The risk of malware infection remains on a constant rise with new infections rapidly spreading every hour, every day. You should careful this growing malware problem by introducing powerful security measures such as Security Advisor and Qualysguard Security Scan, as well as regular security updates to protect from potential threats. Recently, we are all witnessed for new encryption-based ransomware targeting personal files and even network-based devices.
What is an encryption-based ransomware?
Encryption-based ransomware, such as CryptoWall, CryptoLocker, wannacry and TorrentLocker, encrypts files stored on computers, and even network drives. Once infected, you are left with the option to either pay the ransom to regain access to your files or give up all your precious data previously stored on the computer or storage device.
Crucial practices against ransomware attacks on your PC
Ransomware has become a growing threat to home users and small offices with less sophisticated defense systems. Put an end to malware infections, here are some tips and tricks to avoid becoming another victim of ransomware.
Update your operating system
Outdated computer systems are relatively more vulnerable to ransomware attacks. This is why it is essential to perform regular software and operating system updates to improve the security of your computer.
Install a reputable security suite
Install a good antivirus software or a reputable security suite to help you detect and fight off malicious threats, giving you an extra form of protection.
Avoid suspicious files
Stay on guard and think twice before opening email attachments or clicking files from unknown sources. Watch out for suspicious files with hidden file-extensions such as “.pdf.exe”
Disable remote access
Malware often target computers using RDP (Remote Desktop Protocol). Keep RDP disabled if you do not require remote access
Multi-version backup, your best weapon against ransomware
Encryption-based ransomware is getting sophisticated and may not be detected by anti-malware software in time. Once infected, you will be locked out from your own data and there is still no guarantee you can retrieve your data even after paying the ransom! It is highly recommended to perform routine backups to restore infected files and minimize damage. Follow multi-version backup — a robust backup solution allowing you to restore previous versions of the infected files.
Steps to take when discovering ransomware infection
In the unfortunate event that you have encountered a ransomware attack, do not fret. Turn off your WiFi or unplug your network cable—make sure you disconnect yourself from the internet immediately. The next step is to have your computer system completely wiped clean of infection. Make sure your computer is at a clean state before restoring previous versions of files that were backed up.
