Does it happen that when you start your system to perform some crucial work, you get the scary image of a large padlock? The text in the window shows that your data is locked, and to prevent losing it permanently, you have to pay the ransom? If so, the bad news is that you have become the latest victim of ransomware. Ransomware is a significant threat to business as it can encrypt your data and makes it impossible for you to access the data. So, if you consider ransomware merely a tech nuisance, it’s time to think again. We are not scaring you, but being prepared is the first step towards Data Recovery due to a ransomware attack. And, to do so, you first need to know what ransomware is all about.
What do you need to know about ransomware?
Ransomware is a type of malicious software that makes it difficult for you to access the system or data. And, to access the data, be ready to send a massive amount to the hackers. If you don’t pay in time, you will lose the data forever. Ransomware attacks have become extremely common these days as not only business but government agencies have fallen victim to them.
The two most common types of ransomware are encryptors and screen lockers. Encryptors are known for encrypting data on the system, making it difficult for users to use the content unless they have the decryption key. On the other hand, screen lockers block access to the system by using a lock screen. On the lock screen, users will be asked to purchase a cryptocurrency like Bitcoin to pay the ransom. And, only after paying the ransom, users will get the decryption key. In most of the situations, even after getting the decryption key, there is no guarantee that you will be able to get the data back.
Impact of Ransomware on business
After learning what ransomware is all about, let’s find out how it impacts the day to day operations of businesses.
Prevents access to data: The reason why business owners fear ransomware is, because it prevents users from accessing valuable data. The only way to unlock the data is to pay a huge amount to hackers to get the decryption key.
Disrupts regular business operations: Do you know ransomware itself is not a significant threat? The problem arises with the operational impact of ransomware on the business. For instance, a vital business process comes to a halt because of the ransomware attack, resulting in the loss of productivity.
Financial burden: Even if you have a robust recovery strategy, there is no guarantee that you will not experience a ransomware attack. And, once you come under the attack, you will have to spend a fortune for a computer recovery service to get your data back.
Damage of reputation: In most situations, a cyberattack can lead to damage to your reputation; this is the worst nightmare for any firm. Ransomware can be the culprit behind the loss of trust amongst customers. If customers get to know that you’re under a ransomware attack, they will be reluctant to share their personal information and credit card details with you. No matter the size of your business, a ransomware attack can permanently damage the reputation of your business.
Here are some examples that will make it easy for you to understand the impact of ransomware on businesses.
WannaCry: A worldwide ransomware worm that was responsible for infecting over 250,000 systems. And, to prevent the disastrous impact of this ransomware attack, killswitch software was introduced. Proofpoint came to the rescue of firms infected with the ransomware to find the killswitch and destroy the ransomware.
CryptoLocker: This is the current generation ransomware that is financial in nature. The ransomware requires cryptocurrency for making payment. It works by encrypting the user’s hard drive and attached network drives. The ransomware spreads via an email with an attachment that claims to be FedEx and UPS tracking notifications. And according to reports, for recovering data, a huge ransom of $27 million was paid by victims.
Bad Rabbit: This ransomware created havoc in Russia and Ukraine. The attack mostly impacted media companies. The ransomware spread through a fake flash player update that impacts users via a drive-by attack.
NotPetya: One of the most destructive ransomware attacks, the ransomware infects and encrypts the master boot record of Microsoft Windows-based systems. The ransomware is capable of making the target system unrecoverable.
Learn How to Stay Away from Ransomware Attacks
To protect your data from ransomware attacks, you need to perform the following steps.
Always maintain a regular backup of data, especially of your critical data.
Use reliable security solutions to enhance data security.
Use good quality antivirus software and update it for all the devices.
Never open email ad attachments from a sender, whom you don’t know about.
Educate your employees about good data protection measures. For instance, ask your employees to keep sensitive data separately, restrict employee access, and maintain a good backup of data.
Also, since ransomware is a criminal offense, if you become a victim of ransomware, report it to the law enforcement agency.
Measures to take in case of a Ransomware Attack
Now, before you head out to CBL for Trusted Data Recovery service, there are certain steps we want you to perform to prevent the situation from getting all bad. If you suspect any unusual system behavior or your system gets locked, perform the following steps.
Switch off your system directly.
Next, you have to disconnect the LAN cable.
Now restart the system and install the antivirus software.
Scan the antivirus software to discover the vulnerabilities.
Keep a data backup to secure your confidential data.
Apart from these steps, here are some do’s and don’ts you must observe to protect the data from a ransomware attack.
Never fall prey to suspicious links and attachments present in the email messages.
Like the links and attachments, never open suspicious images.
If you encounter any phishing or suspicious email message, never respond to it.
In case of any suspicious email, contact the system support department.
Make sure the security solutions on the system and servers connected to the network are up to date.
Also, make sure the operating system, antivirus software, and other software running on your system are up to date.
How can CBL Data Recovery come to your assistance?
Ransomware can be a real threat that enables cyber extortion for financial gain. There is no direct way to protect against a ransomware attack on your network. The best way to protect your system is to have real ransomware to test your defenses. For this reason, we have introduced a ransomware simulator that does encryption of information on the network but has an off switch in a way that is under your command and also enables you to decrypt the data as well.
Want to know how the tool works? Let’s find out!
The tool is developed and works using windows PowerShell Encrypter /Decrypter. If you want to learn more about what PowerShell is, we are ready to help you.
We have developed two PowerShell scripts that work as a ransomware simulator. The one script encrypts the data while the other one decrypts the data using a public/private key pair. The tool is a simulator that tests your system’s defense against actual ransomware. The decrypter is intended to ensure that your files are not destroyed permanently.
WARNING: This tool encrypts files. Please use responsibly. If you are unfamiliar with PowerShell, DO NOT use this tool. Here are the step by step guidelines on how the tool works.
In descending order, the network drives are enumerated and sorted.
The drive with the lowest letter will be attacked. It enables you to control what shares are affected. We use drive letter Z as our attack drive for the convenience of the testing environment.
Folders are not included. Only the files that have been discovered are included.
Each discovered file is encrypted with the public key that renders the file in an unreadable format.
The scripts stop after all files are encrypted.
