Keep Safe From Malware & Ransomware

Ransomware is becoming more and more common across both personal networks and enterprise level networks and the effects can be devastating. The fact that ransomware can completely lock a network and encrypt the data held within it should shine a light onto why avoiding and preventing ransomware is so important.
In this guest post by 5u IT Services, we look at what ransomware is, how you can protect yourself from it and what you can do if you’re infected.

What is ransomware?

Ransomware is a variant of cyber-attack that involves hackers carrying a computer or other device and insisting payment. The attackers use malicious software (Malware) by downloading it on a victim’s device and using it to encrypt their information. Most ransomware strikes are targeted toward companies and big corporations, but it could also affect people.

There are a number of ways to safeguard yourself from ransomware, and many attacks might have been averted had the victim exercised care in their everyday usage of their devices. Security specialists have released tips to help users protect themselves from those cyber-attacks, especially after a rise in domestic and international cases:

1. Be wary of emails, pop-ups and dodgy apps

According to TrendMicro, Ransomware is often spread through emails containing suspicious links. Once clicked, the hackers could access the user’s computer and subsequently their files, which they can block and freeze. That is where they endanger the victim with the reduction of the documents, should they refuse payment.

But, there are ways that you may spot a bogus email. Look closely at the email address to find out whether it is valid. What’s more, you could try hovering over hyperlinks (without clicking them) to see if they guide you to dubious web pages.

Remember that banks and credit card companies won’t ever ask for private information such as your password or credit card details.

‘Malvertising’ is a brand new method which includes the embedding of malware in adverts on sites you are familiar with and trust. They are frequently pop-ups and occasionally promote software to remove malware. Never click on these adverts, but close the windows instantly. To prevent malvertising appearing on your trusted sites, you can use ad blockers, or rather, repair known browser security holes.

Lastly, not download an app that has not been certified by an official shop, and always read testimonials before installing anything to prevent allowing attackers access to your personal computer or mobile device.

2. Back up all of your documents

If you make certain that you back up all your information daily, you’ll be immune to attacker’s threats if your servers or computers are blocked. But you need to make certain you use an external drive that’s offline so that the ransomware cannot reach them. By backing all of your information onto external drives which are not directly linked to a desktop system, however, would let you erase all information from the attacked device and restore it with the backup, in the event you fall victim.

3. Always install valid updates

Upgrades are usually released to fix bugs that may cause your device more vulnerable to ransomware and other strikes. Therefore, download the most recent version of your applications whenever it becomes available.

4. Install an antivirus program

Antivirus software can detect malware and block it from penetrating your pc before it becomes visible or a threat for you. However, be sure that you only download such software from reputable companies such as Bitdefender, Kaspersky Lab, and Norton.

5. Never pay the ransom

Paying the ransom will sadly only encourage attackers farther, and there is no guarantee your files will be recovered. Should you back up your data frequently, however, you are able to restore your files from that.

If you’re a part of a business ensure you disconnect from the corporate network and the internet to steer clear of malware spreading to other apparatus. Also disable Wi-Fi and Bluetooth since these may also be an entry for ransomware. Report the crime and seek help from an expert who majors in data retrieval, so it’s possible to discuss your alternatives. In extreme cases, your only option is to pay the ransom, but DO NOT do so unless you have spoken to an expert first.

For businesses, Ransomware is an absolute nightmare and can run riot through a network. For that reason, we’d always suggest ensuring that you have adequate security patches installed as well as robust antivirus and firewall solutions in place.
