The dependency of professionals and businesses on the electronic form of data has grown lately. So has increased the attacks on the data.
Cyberattacks have a long history and for the most of it, damaging the data was their prime target. However, attackers have now realized that data is valuable to businesses and professionals, and they can even be forced into paying for it. Riding on this realization, ransomware attacks have cropped up as the most damaging form of cyberattacks for businesses.
What is Ransomware?
Ransomware is a malicious program that restricts the access to the information until a ransom is paid. Most malware follow the encryption technique to block this access while cryptocurrency is the common form of ransom demand.

Protecting your Data Against Ransomware Attacks
Ransomware is malware that impacts data, so it has to make a way to the device on which data is stored to cause any damage. By deploying proper security in the paths that ransomware may use, you can protect your data. Here are the some of the critical methods that can help you:
1. Anti-spam Your Email
Email is the most commonly used method to deliver ransomware. Therefore, starting by safeguarding your emails is an excellent way to begin.
Following are some of the practices for filtering out the ransomware:
- Avoid entertaining emails from unidentified/doubtful senders. It is advisable to notice the sender’s email address carefully. Hint: firstname.lastname@example.org is NOT email@example.com (Yes, you need to pay attention)
- Pay attention to the file extensions of attachment. What may appear as PDF could be an EXE file.
- Some email services offer built-in spam and antivirus check. If your email service is not providing this feature, you can opt for the third-party email security service.
2. Be Attentive While Installing Software
It is easy to say and understand that you should not install ransomware. Attackers understand that as well and therefore attempt to find different methods to trick you into installing ransomware.
Ransomware may appear to be a useful software intended to do some other task, while a malicious program may be wrapped in it as an add-on. Follow these steps to stay safe.
- Download software only from trusted vendors.
- Run an antivirus check on the downloaded setup.
- There are some software (usually the freebies) that carry the instruction to install additional software with them. Ensure that you uncheck the unwanted add-on/extensions during the installation process.
- Be watchful to the permissions that the software requests. Don’t allow dubious permissions, such as – access to admin rights, etc., if you are unsure about the importance of the permissions.
3. Update/Patch OS and Software
Cyber attackers are continuously targeting the loopholes in Operating Systems (OS) and other software to find a way to install ransomware on the system. Security update or patch for OS and software is meant to fix these loopholes.
It is recommended that you install the security updates on time to keep the attacks away. Most of the modern OS and software offer the option of automatic updates, which is a smart choice to avoid manual efforts with it.
Important: For software that you are not familiar with or its operations involve integration with various other software, it is recommended to take the assistance of an expert.
4. Secure Backups
If a ransomware strikes, backups are your easiest way to get past the attack and restore your operations. Apart from ransomware, there are many more reasons why regular data backup is crucial. Still, users tend to ignore it out of sluggishness mostly. Going with the automated backup policies is the best trick to stay safe.
Some attackers know that data backups can nullify the reason for the attack and they try to attack the backups too. So, it is essential to consider the security of the backup storage. Ace Cloud Hosting backs up the data on multiple locations and in an encrypted format to ensure complete protection of the data.
