Tzw Ransomware
Tzw is a ransomware tool uncovered by cybersecurity researchers. Upon execution, the Tzw Ransomware encrypts the files on the infected device and changes their titles by appending a '.tzw' extension to them. A ransom-demanding message delivered as a text file named 'readme.txt' is then created, asking the victim to purchase the decryption key from the cybercriminals responsible for the attack to recover the impacted data.
In the vast majority of ransomware attacks, decryption is usually impossible without the attackers' involvement. Sometimes victims do not receive the promised decryption keys/tools even after paying, making the consequences of the malware attack even more severe. Generally, it is strongly recommended not to follow the ransom demands of threat actors since data recovery is not guaranteed and paying also supports this criminal activity.
Protect Your Devices from Threats Like the Tzw Ransomware
Ransomware attacks are becoming increasingly more common and harder to prevent. That's why it is critically important to know what measures to take to protect your devices and the data stored on them from being manipulated by threat actors.
- Ensure You Have Recent Backups
Having a recent backup is critical to recovering quickly after a ransomware attack. It should contain your most important data as recent versions of it so that if something gets encrypted with ransomware, you can easily recover it using clean unaltered versions stored elsewhere. Make sure to back up your data frequently and consistently, preferably with an automated process.
- Install Security Software & Updates on All Systems
Security software plays an essential role in preventing ransomware attacks by being able to look for threatening activity continuously. Equally as important is to keep the operating system and other software on the device up-to-date with the latest security patches.
- Regularly Scan Your Network
Periodic scans of servers, applications, databases, etc., help identify any weaknesses or vulnerable areas which may be exploited by hackers. Additionally, they also reveal signs of suspicious activities and allow for adequate and timely response, mitigating the potential damage caused by such activities.
