The more the vulnerabilities in your system, the more is the risk of a ransomware attack. So, here are precautions you should take in order to prevent yourself and your company from being attacked by ransomware.

Tips to Reduce Risk 

Never open all your emails

The cyberattackers use multiple ways to send the harmful malware to your computers. The most common way is through emails. Do not view or download email attachments from suspicious senders. Double check the email senders and the attachments. The attachments include PDFs, Word documents etc. Check if the email address is correct and inform your team to be careful about the issue. Also do not open attachments if they ask you to enable macros. As running malicious macros will take away the control over your system, better not to open such untrusted attachments enabling macros. If you fail staying away from such malicious attachments, you may end up providing full access to those hackers.

Do not click on suspicious links

The other way to prevent your files and data from skipping into the hands of cyber attackers is avoiding clicking on spam links. Here you might get a question ‘How can we know if it is a spam link?’. Well, it is difficult to identify the normal and spam links as some legitimate websites have these malicious links unknowingly. So, never click on any links if you find them suspicious. Because if it seems suspicious, it might be suspicious and you might end up as the victim. Also, never visit websites that appear as spam sites. They may automatically redirect you to some other malicious sites which read, hold your data and take control over it. 

Once they encrypt and hold your data, they reach you demanding some ransom amount to unlock the access and recover the data. In most of the situations, victims fall under this trap and end up paying but fail to recover the data. After all, they are untrusted attackers and there is no guarantee that they will give you access to your systems. So, the right and only way is to protect your system from the attack.

Stay cautious of your downloads

In order to shut the doors for the cyberattackers, the other thing you need to take care of is your downloads. Be aware of what is happening in your system. Avoid downloading any files and software from untrusted websites. Only visit and download files from reputed sites and sites which have https in the url.

Say ‘no’ to giving personal info

What do you do if someone from the ‘X’ organization calls you to inquire about your information? Yes, this is one of the tricky ways cyber criminals use to find out loopholes and vulnerabilities of your security system.  Act smart by not giving any personal data or any information of your company to strangers. They send texts, emails and call you asking you personal info, simply ignore and inform your security personnel and alert your team to  stay aware of these issues. 

If you are not sure the call is really spam, you can directly contact the company and verify if it is genuine. But do not risk sharing your data before verification.

Stay away from unfamiliar USBs

If you do not know where the USBs came from, better avoid using them. Do not insert unfamiliar storage devices into your devices. If the devices like USBs or pen drives etc. are infected with malware, your PC will also get infected. If those devices are wantedly infected with ransomware by cyber criminals, you will end by playing a victim.

The software security teams work on updating the software based on new security patches and closes the security holes of vulnerable applications frequently. So ensure you update them accordingly challenging the cybercriminals.

In recent years, the ransomware attack has become wildly popular, hence the internet security solutions came into existence. To protect your systems from malicious malware, use such anti-malware solutions. These software prevent your system from downloading or streaming infected websites or files. 

Also, update the security software most frequently to gain the highest level of protection from harmful ransomware attacks.

Whether you have a threat of ransomware attack or not, you must always have your data backup. In case when you experience a cyber attack, you will have all your data in backup that reduces the downtime of your business. But make sure you plug out the external storage device after the backup. You can store the data on cloud services or on external devices frequently. These will help you retrieve your previous unencrypted versions, in case your data is encrypted by ransomware. Keep reminders to backup your data frequently or enable automatic backup to prevent loss of your useful data.

Steps to taken after ransomware cyber attack

What if your computer or important data is already infected by ransomware? First thing, do not panic. The focus point of ransomware attack is the attackers hold your data, lock your screen denying access to you. They demand some amount and promise to unlock the access in return. If the data is so important the only option you could see is paying them. But remember, do not pay them. If you pay them, indirectly you are encouraging them to infect other organizations or your organisation once more. Moreover, encouraging such activities also count as a crime. It is never late to act smart…
