Make a recovery plan against encryption-based locker viruses(Ransomware)
Ransomware is a rising threat against both business and home users that targets computers and network-based devices. A simple yet effective method of mitigating the threat of ransomware is to ensure that you always have up-to-date, remotely-stored backups. QNAP NAS is an ideal backup center that includes comprehensive backup features and supports point-in-time snapshots to help individuals and organizations protect important data, restore files, and avoid downtime.
What is locker ransomware?
Locker is a file-encrypting ransomware (Cryptolocker, CTB Locker, TeslaCrypt, and others) that encrypts files found on local drives, removable drives, mapped network drives, and even Dropbox mappings. Victims will be extorted a ransom to decrypt the affected files, or they will be unable to open the affect files ever again.
And why is locker ransomware so troublesome?
- Ransomware is typically spread through phishing emails, and mostly hidden in emails as attachments like .zip, .pdf, .doc, .exe, .js files, and more. It is difficult to identify, and self-spreading.
- Traditional antivirus may not detect next-generation ransomware.
- Locker ransomware uses asymmetric encryption or more advanced encryption methods which can be difficult (if not impossible) to break locally.
- Victims are forced to pay (normally by untraceable means) to restore their files, or they face losing them forever.
Back up with QNAP NAS to save your files
While the first line of defense against being affected by malicious software is being careful and practicing sensible usage habits (regularly updating your software, not opening untrustworthy emails, not visiting unknown websites, etc), you should always remember to back up your data.
QNAP NAS provides a simple solution for backing up/restoring files and data. Its Linux-based QTS operating system makes it more secure than Windows® systems that are more at risk from being attacked. Moreover, the native support for point-in-time snapshots that are operated separately from the file system makes QNAP NAS a reliable backup solution for reacting quickly for backing up and restoring important files and system data.
Snapshots: React quickly for backing up and restoring
Snapshots record the metadata of files outside the file system and allow users to preserve and restore multiple versions of the same file, folder or even the entire volume. If ransomware attacks or an unexpected situation arises on your system, you can quickly and easily revert back to the previous state that the snapshot has recorded.
