Ransomware is on the rise!
In 2015, a ransomware trojan called Cryptolocker caused global chaos. Unfortunately, another form of ransomware is becoming a serious social issue once again this year.
The name “Ransomware” is a combination of ransom (The sum or price paid or demanded) and ware (terms for classes of software). Once the ransomware has been released into your device, all your personal files will be encrypted and you can’t decrypt it unless you pay a ransom. Once it’s encrypted, you can’t use the files until you find out the attacker’s decryption key. Sometimes, attackers refuse to decipher even after victim pays a ransom. We don’t recommend to pay a ransom because there is no guarantee the attacker will give a decryption key to restore your files. Also, paying a ransom to attacker basically offers an incentive for other attackers to get involved in this activity.
If so, how should we protect our devices against ransomware?
Backup your important data in cloud storage
Preventing is the most important keyword in cyber-attacks like a ransomware. Ransomware propagation is usually done by Drive-by Download way, which infects your device through security vulnerability, not by downloading certain file or program. Most of the time propagation made through Online Ads, which called Malvertising. Thus, users don’t know when to be caught by ransomware, so it’s important to prevent it in the first place.
In user’s point of view, the best way to prevent ransomware attack is to backup data. It’s good to save it in the external storage such as external hard drives and USB or use cloud storage to back-up your data. Ransomware even attacks smart devices such as a smartphone, so you need to backup your pictures or videos in storage too. In this point, it would be more easy to store both data in cloud storage.
Stay on the safe side
The coast is not clear even after data has been stored in the cloud storage. Recently, there are cases where ransomware even attacked files which were saved in cloud storage. It mostly happens through the integration between PC or mobile and cloud storage. In other words, the files which are already infected by ransomware has been integrated to the cloud storage.
If we turn the tables, we can see that cloud storage is very safe from direct ransomware attack unless infected files have been uploaded. It may little uncomfortable, but we highly recommend to turn off the synchronization when uploading important data to cloud storage. Once again, taking precautions to protect your information is the most important thing to protect against ransomware.
If you haven’t made a backup of your data, It’s not late yet. Let’s prevent, and be safe 🙂
