 Why Did the FBI Issue a Warning for Hive Ransomware?

A variety of ransomware gangs target specific industries and demand a ransom in exchange for preventing service interruptions. As a result, the Hive ransomware gang has emerged and has carried out many attacks this year alone, which is a nightmare for the healthcare industry. In terms of ransomware, this is a very bad example.

In addition, in response to the seriousness of the situation, the FBI issued a public statement with technical facts regarding the Hive ransomware. So, how exactly does the Hive ransomware operate? And what measures can you take to safeguard yourself?

What Is Hive Ransomware?

In June 2021, the malware known as Hive came to public attention. This ransomware attack, in contrast to certain other ransomware outbreaks, is thought to be affiliate-based ransomware. In other words, it employs a model known as "Ransomware-as-a-Service."

This business model allows any criminal to carry out ransomware attacks and benefit from them without having any prior knowledge of how it all works. Yes, a ransomware assault can be launched by an attacker who does not know a single line of programming code whatsoever.

The FBI Issues a Warning Regarding Hive Ransomware

Earlier this month, the Memorial Health System was targeted by the ransomware organization, which forced the hospital to cancel procedures and redirect patients for a period of time.

As a result, the FBI issued an advisory to inform the public about what to look out for, including the infamous Hive ransomware organization, which has been on the rise recently.

How does Hive Ransomware Works

As part of its effort to guarantee that the attack is successful, Hive ransomware employs a wide range of tactics, methods, and procedures (TTPs).

It employs the typical method of phishing to infect a machine, and you can expect a malicious file to be attached to an email when you open it. Although the file appears to be innocent, the ransomware is able to infiltrate your system and begin operating as soon as you open it.

The Hive ransomware also analyses your system for any programs associated with backup, antivirus or other security protection, and file copying, amongst other things. After that, it ends all similar processes in order to deactivate the protection measures.

Upon infection, it encrypts files on the network and demands a ransom, along with a warning that the files would be leaked to a site that can only be accessed through the use of the Tor browser.

The impacted files have a .hive extension, which makes it easy to identify them. The Hive ransomware also includes a .bat script that is hidden in the affected directory and is responsible for cleaning up the files when the encryption process is complete.

After you've finished cleaning up your original files, create a second shadow.

A bat script is also dropped by the ransomware in order to clear up any shadow or backup copies of your data that have been discovered by the malware.

Everything takes place without the user being notified. As a result, you will not be aware of its presence until you come across a directory containing hive encrypted files. In addition, you will notice a text file that contains instructions on how to decrypt the data. This will direct you to a sales department URL, which can only be accessed through the Tor browser, which will connect you to the ransomware perpetrators for a live chat in the meantime.

After that, you will have between two and six days to pay the ransom. If you are currently in the process of negotiating with them, they may decide to extend the deadline.

How to Protect Yourself Against Hive Ransomware

Hive ransomware takes advantage of phishing emails to trick users into installing legitimate software that could be critical to your company's operations. For example, you could be enticed to download a 7zip executable file (legitimate software) and then become infected with ransomware as a result.

The attackers also appear to be employing file-sharing sites such as MEGA, SendSpace, and other similar services to change the file URL to appear innocent and trustworthy while doing so.

So keep an eye out for links that appear to be dodgy. You should also double-check and validate your information before downloading any executable files to your computer. Don't click on anything unless you're quite certain it's what you want to do.

You should also back up all of your vital data to the cloud or a separate storage drive (that is not connected to your network) to avoid having to pay the ransom.
