What Are Ransomware Attacks? And How To Get Secured

In recent years, ransomware has become increasingly prevalent, affecting everyone from individuals to state governments. The revenue generated by the ransomware virus is steadily growing day by day. The new ransomware, on the other hand, will bring in more cash. You’re probably aware that if you’re infected with ransomware, you’ll have to pay a ransom to get your data back.

What is a ransomware attack exactly? What is the mechanism behind it?

A ransomware assault is essentially a sophisticated form of data theft. Ransomware software is malware that infiltrates a network or a single computer via an unsecured access point. Perhaps a port is left open, allowing hackers to get access through the back door. It’s possible that someone in their inbox clicked on a malicious link. Perhaps they were the victims of a drive-by download using an exploit kit after clicking on advertising.

Whatever the reason, once ransomware has been installed or got into the system, it can do a variety of tasks depending on the strain. Some ransomware locks your screen, locking you out of your computer but leaving your file system unharmed. However, more destructive malware goes further.

It will encrypt your whole file system, rendering data on your computer or network unrecoverable until you pay the ransom for the decryption key. There are varieties of this sort of ransomware that can extract files rather than merely lock them, exposing businesses to massive privacy breaches and data theft.

Hackers will demand a ransom, which is usually paid in Bitcoin, a difficult-to-trace online currency. The hackers will release the files and return control of the computer or network to the folks who paid the ransom. However, even if they do so, the ransomware remains on the system, ready to be reactivated whenever the hackers want more money.

8 ways to prevent ransomware attacks

As we know, prevention is better than cure. To avoid their attack, the most important thing to do is to prevent them. Here are eight ways to prevent ransomware attacks:

1. Make a copy of your data:

The most important thing you can do to combat ransomware attacks is to keep your backups up to date. You may lose your document if you are attacked with ransomware. As a result, having a frequent backup to an external device or backup service is critical.

2. Display file extensions that are concealed:

One of the simplest ways for ransomware attacks to spread is through a file with the extension “.PDF.EXE,” which uses Windows’ default practice of hiding recognized file extensions. It would be simpler to recognize suspicious files if you re-enabled the ability to see the complete file extension.

3. EXEs in the email should be filtered out:

If your gateway mail scanner can filter files based on their extension, you must reject emails that contain “.EXE, VBS….etc.” files.

4. Disable AppData/LocalAppData directories from being launched:

You may use Windows rules to prevent the ransomware from running its executable from the App Data or Local App Data files, which is a common occurrence. If you have genuine software that you don’t wish to execute from the regular Program Files directory but instead from the App Data directory, then this rule does not apply to it.

5. Installed software should be renewed or updated:

Malware authors rely on users using outdated software that they may exploit to gain access to your computer invisibly. If you make it a habit to update your software, you may dramatically reduce your risk of being victimized by ransomware. Activate automatic updates or visit the program vendor’s website directly.

6. Make use of a trustworthy antivirus product:

Both anti-malware software and a firewall are recommended to safeguard you from identifying threats or unusual activities. Malware authors often send out new variations and try to evade detection, so having two levels of security is critical.

7. Immediately disconnect from Wi-Fi or unplug from the network:

If you execute a file that seems like it could be ransomware, but you don’t see any ransomware symptoms, you should cease communicating with the C&C server before it encrypts your data. You might be able to lessen the impact by disconnecting from the network. Because encrypting your data takes time, you may be able to halt it before it destroys your contents. This method isn’t flawless, but it does work to some extent.

8. Utilize system restorer:

If you have a system restore enabled on your Windows system, you may use it to restore your system to its original condition. However, specific modern versions of ransomware, such as Cryptolocker, can remove your “Shadow” files from System Restore, which means that when you try to replace your malware-damaged copies, those files will not be there.

Wrap Up!

Ransomware attacks are a significant threat to computer cybersecurity, and if you’re attacked with a ransomware assault and don’t have sufficient offsite backups, you’ll lose time, money, valuable secret data, and your customers’ faith.

So, it’s vital to stay one step ahead of hackers. Choose an affordable agency that places your security at a high priority that secures your network forever.
