Ryuk Ransomware Prevention Services

Ryuk ransomware is a type of ransomware specific to crypto that uses encryption to stop and block any access to a system, your devices, or files until a ransom has been paid. It can be a difficult recovery process to go through. If you are under attack, Ryuk will demand payment via Bitcoin cryptocurrency. It will direct anyone under attack through their systems to deposit the requested ransom in a Bitcoin wallet and the amounts can and will vary but are generally large. Ryuk is often the last piece of malware dropped into any infection cycle. These start with either Emotet or TrickBot and can cause a lot of harm. Multiple malware infections may greatly complicate the process of recovery.

A Little More About Ryuk Ransomware

The majority of Ryuk Ransomware attacks can be traced back to either Remote Desktop Protocol access or email Phishing as the attack starting point. This is due to the prevalence of poorly secured RDP ports. There is also ease with which Ransomware distributors are able to either force themselves onto the device systems, or purchase credentials on dark market sites to corrupt. Companies and businesses that allow employees to work from home or contractors to access their networks through remote access, without taking any of the proper protections, are at risk of being attacked by Ryuk Ransomware. Email phishing is also increasingly likely in Ryuk attacks.

Ryuk is primarily spread via other malware dropping it onto an existing infected system and often is the last element in a cyber-attack. Finding the initial starting point on a system for analysis is difficult. This is due to the fact that the main element deletes itself after the initial execution, which can cause issues with finding the Ransomware issue in the first place. The dropper creates a file for the payload to be saved to. However, if the file creation fails, the dropper will then try to write it into its own directory, which could cause more problems.

How Long Do Ryuk Ransomware Incidents Normally Last?

Ryuk incidents tend to be much longer than other types of ransomware. This is due to the high ransom amounts demanded through Bitcoin and also the labor-intensive nature of the decryption tool. Unfortunately, Ryuk Ransomware has a low data recovery-success rate after a ransom payment is made.

Ryuk Ransomware typically appends a standard ‘.ryk’ to encrypted files and this is how such an attack can be identified. There is a lot involved, but this is where we as experts can help you identify the problem and also enable you to get back on track with your business and your devices.
