Are your files encrypted after a ransomware attack?

Here are 4 file decryption options!

It is really harmful for a company not to be able to operate due to a ransomware attack. indeed, an attacker locks or encrypts the files.

Our company can effectively help you recover from ransomware attacks! We have helped many customers to recover their data and decrypt their files.

Below we explain how:

  • files are encrypted or locked after a ransomware attack
  • to decrypt them.

In other words, a recovery company analyses all encrypted files and help the victim decide if it is necessary to pay the ransom.

What are the options?

Firstly, with this guide we explain the choices that customers have.

Through the 4 options, we show how we collect any information that is crucial for ransomware decryption.

In general, the purpose of this analysis is to teach you:

  • What information is necessary to be collected.
  • About the stages of the investigation when decrypting or unlocking your files after a ransomware attack.

Are you victim to a ransomware attack?

When you fall victim to such an attack, you may notice:

  •  Suspicious notifications from network servers.
  • No-functioning  databases.
  • Data not accessible by employees.

Once you understand something’s wrong, you’ll try to investigate what’s going on.

Particularly, you may realize that all files on your network have been renamed. It is possible to locate notes demanding a ransom. You may also find a screen that asks you to send mail to someone, in order to have your files back.

Therefore, after being victim to a ransomware attack, you cannot have access to your locked files.

Consequently, a business that does not follow specific security policies and procedures,  is prone to ransomware attacks.

What are your weak spots?

The 3 most common causes for ransomware attacks are:

  • Open Remote Desktop Protocol Ports (RDP)

If an organisation has not properly tuned its security parameters, it can leave Remote Desktop Protocol Ports unlocked.

After that, a hacker manages to connect to a company’s network, in order to install ransomware. He opens back doors so he can attack later. Therefore, every company should close the RDP port on time to endpoints and servers.

  • Phishing attacks

Ransomware administrators choose mainly to invade networks, through phishing attacks. In addition, they use networks of devices to attack via phishing messages.

With these emails they try to deceive the recipient. Moreover, they persuade him to click an unsafe connection and an infected attachment.

Thus, they manage to secretly install a ransomware virus or other malware.

It is a fact that attackers find imaginative ways to make phishing messages seem normal.

So it’s getting harder and harder for anyone who gets a message like that to realize what is happening.

As a conclusion, a company must regularly train all its staff in Cyber Security.

  • Passwords that have been compromised.

A company that does not choose a proper policy for protecting its network ,is vulnerable to such attacks.

In particular, the risk is greater when authentication is not properly configured.

Therefore, passwords are exposed and very easy to break. This is another way in which a ransomware administrator can penetrate your data. So, employees must choose strong and unique passwords.

Finally, through the great number of ransomware attacks, we can realize the importance of digital forensic research. In this way, a ransomware victim will be able to understand exactly what has happened and how to react.

4 Data recovery and Decryption options

1. Recover your data from a backup.

  • You must keep your files stored in the cloud or offline. It is a safe way to protect them from viruses and any malicious attack.
  • Moreover, you have to check Windows Shadow Copies. Even if it’s impossible, you might find them without changes.
  • You should also Check the on-site backup. The data is either encrypted through ransomware or deleted manually.

2. Recreate the data.

Even if you are a victim to a ransomware attack, you may be able to retrieve your data as following:

  • By manually re-entering your data. This is possible from the physical copies you keep in paper form.
  • You can export your files that you may have sent as attachments in e-mail messages.

3. Break ransomware encryption.

It is really rare to succesfully break a ransomware encryption. This does not mean that a data recovery company will override this option.

Obviously, there are ransomware encryptions with vulnerabilities. A data recovery company will take in consideration this weakness, especially when there is not time pressure.

If the effort is successful, a customer can save a lot of money. However, in reality most efforts are not successful.

Without a dubt, ransomware is a cryptovirus that uses complicated algorithms and secret keys. By combining these powerful tools, the attacker locks the company’s files, with the help of strong encryption and malware.

Are you scared from a ransomware attack?

The original purpose of creating encryption has been reversed.

Indeed, from a defense tool, it evolved into an attack tool against unsuspected victims.

For this purpose, there are free platforms to help you identify ransomware and find out if decryption is possible.

However, primarily you will need the opinion of a qualified analyst, because usually encryption is unbreakable.

4. Pay the ransom.

Most companies don’t have time to waste trying to crack ransomware encryption.

If they lose time, they’ll have significant losses in profits and expenses. So, they are forced to pay the ransom demanded.

On the other hand, there are also companies that – for special reasons – do not wish to pay the ransom.

Only specialized data recovery personnel  can help you decide concerning a ransomware attack.

Below is a list of proven unbreakable ransomware encryptions:

• Mamba
• Dharma2
• Phobos
• Netwalker/Mailto
• Matrix
• Mr. Dec
• Maze
• Cryptomix Revenge
• Globeimposter
• NM4
• Sodinokibi
• Lockcrypt 2.0
• Rapid
• Nozelesn
• Major
• Snatch

How can a data recovery company help you if you fell victim to ransomware attack?

The first step is to search for an experienced ransomware recovery company.

Such an experienced company must:

  • Estimate the current situation due to the attack.
  • Analyze what are the options to deal with.
  • Explain you its experience in similar cases.
  • Inform you on the cost of the procedure.

In the second stage, the company you choose should:

  • Understand what ransomware variant you have to face.
  • Determine after analysis whether encryption can be broken.
  • Collect information about the attacker.
  • Provide immediately digital currency in case of ransom payment.
  • Adjust properly decryption programs in order to avoid delays.
  • Repair corrupted files and databases.

In conclusion, through the above procedure you will collect all information needed to prevent corresponding future attacks.
