To date, we continue to enjoy the internet, but literally, we don’t know the possibility of getting infected by a ransomware file. At least there are 54 different versions of ransomware today, with each one of them having multiple variants. Unlike malware which it intends to steal your personal information to get unauthorized access, ransomware exists to take your money.

The biggest problem with ransomware attackers infects your network which becomes critical for your business, and you have no option but to pay them. You can imagine the blow when business data is no longer available for your routine activities. You can’t run the business unless you get your data back.

For instance, in 12th May 2017 saw the most dangerous cyber attack in history. Ransomware- Wannacry spread through the web in Europe in Windows OS devices. Within a few hours of the spread, over 200,000 devices were infected with big institutions like banks feeling the impact.

How does ransomware get the chance to store decryption key on your hard drive?

90% of ransomware exists on the internet, and that’s why the web remains a primary ransomware vector. All it takes is one click on a malicious link, a spam email or downloading a malware program that after that download ransomware without your consent. This is the typical way that ransomware ends up in your hand drive.

But today, things are getting different for ransomware attacks due to many activities running on the web. Attackers are using a dangerous ransomware malware- called CryptoWall which is injected as a link in legitimate advertising websites. CryptoWall will use JavaScript program to download and run ransomware with you not knowing it just happened.

In this moment when you click on a link in a spam email or a connection over the web you potentially activate malicious documents. With ransomware installed on your hard drive, it will take a few seconds to get your data encrypted, and they will give you a few days to pay thousand dollars to get it back.

Why ransomware goes undetected by antivirus programs?

Ransomware evades antivirus products, cybersecurity researchers, malware researchers, and law enforcement by using several evasion tactics. Here are some of the tactics that ransomware malware uses to keep the anonymity of its distributors:

1. Ransomware includes features like TOR and Bitcoin traffic anonymizers to receive payments as well as avoid being tracked by law enforcers.

2. It deploys domain shadowing to hide any communication between the cybercriminals automatically serves and the downloader.

3. Ransomware uses an anti-sandboxing mechanism such that it is not traced at all by the antivirus.

4. Command and control servers are encrypted, and it, therefore, becomes difficult to trace the traffic that ransomware is being transferred.

5. It can mutate enough to create a new variant that sticks on the ransomware mission.

6. It employs encrypted payloads that enhances more time for ransomware to unfold as well making it difficult for antivirus to detect it.

Since almost everything is done online nowadays, outdoing ransomware becomes impossible. Many victims just find themselves paying significant cash to retain essential files.

Actions you should consider against ransomware attacks

1. Backups

Backing up your important files to local devices and servers is the best defensive mechanism against ransomware attacks. Even if attackers manage to lock your computer, you won’t pay them a single coin.

You can always avoid clicking on suspicious files and ads or scanning them before opening
