Ransomware – What and How?

So, what is ransomware? Simply stating, it is a type of malware which converts your data into a code, locking you out. In other words, the attacker keeps your data as a hostage and demands a ransom in return for access to that data. All of the data is still present on your computer but is now under encryption, rendering it inaccessible. The attackers ask for money as ransom and give you a deadline to comply.

Ransomware rose to prominence with the popularity of cryptocurrencies that can be used for untraceable payments of the ransom – like Bitcoin, Litecoin, Ripple, etc. Almost all verticals of businesses have been attacked.

What are the Different Types of Ransomware?

Ransomware comes in different forms, shapes, and sizes. The most common types of ransomware are:

  • Lockers
  • Scareware
  • Crypto malware
  • Doxware

 

How to Protect Your Business Against Ransomware?

It is said that the best protection against ransomware is prevention because it’s difficult to catch the attackers if their attack is executed. Here are a few pointers which you need to keep in mind:

  • Use a Security Software: It’s important that you make use of a credible security suite that comes with enhanced, business-class antivirus features. This should be regularly updated for protecting against these advanced cyber threats.
  • Update your Operating System: Ransomware attackers most often exploit systems that haven’t had the security patches updated.
  • Use Cloud Services: Cloud services usually keep the last file versions and can help you roll back to the unencrypted forms of the attacked files.
  • Keep your Data Backed-up: If you already have your files backed up to an external hard drive, then the attacker will not be able to have leverage over you.
  • Do not Open Email Attachments Automatically: As a matter of caution, do not open any emails or attachments from unknown sources.
