How do I know if Avaddon Ransomware has infected my system?

If you are unable to access your data, receive notice that your files have been encrypted, and see a demand for a ransom to regain access, it may mean your system is infected with Avaddon ransomware.

Avaddon Ransomware has been known to the cybersecurity community since September of 2019. Files encrypted by Avaddon generally have a random string of lower and upper case letters as a file extension. It also changes the desktop wallpaper of affected computers. It uses both AES and RSA encryption standards. There is currently one known free decryptor for Avaddon, but it only works under certain conditions. The Avaddon gang has reportedly fixed their code so that the free decryptor no longer works.

  • How do you know if Avaddon Ransomware has encrypted your data?
  • Avaddon Ransomware creates and leaves a text file named *EXTENSION-readme.txt* on your Desktop, or sometimes in each encrypted folder.
  • Your file extensions change to a string of random upper and lower case letters, along with a ransom note which instructs you to visit a hidden service where attackers attempt to extort you.
  • You suddenly notice no desktop wallpaper, or your wallpaper has been changed to communicate a threatening message as an extension to the ransom note.
  • Your CPU is pegged at 100% utilization, even when intensive applications do not appear to be in use.
  • Your Desktop PC or laptop is extremely slow and operating at a speed which is much more sluggish than usual.
  • The hard disk appears to be reading and writing at 100% capacity in the background, even though no drive intensive applications are in use.
  • You are unable to use your antivirus software or find it deactivated.

What should I do if and when my data has been encrypted by Avaddon?

  • Disconnect your system from the network immediately. For more details, please visit our complete guide to Ransomware Response.
  • It is better NOT to talk with the attackers, as they are skilled at taking advantage of inexperienced negotiators.
  • Report the crime to the relevant law enforcement authorities. For a list of relevant offices, see our directory.
  • Ensure that the affected machine is shut down. If left on its own, Avaddon may continue encrypting your data in the background.

The groups that operate Avaddon ransomware are known for targeting large organizations. The gang is known to customize ransom demands based on the annual revenue of their victims.

The average Avaddon ransom amount is somewhere around $40,000. Ransoms are usually paid in Bitcoin. Most quick-buy methods of purchasing Bitcoin via methods like PayPal or credit card will also apply a fee of up to 10%.

Downtime resulting from Avaddon ransomware is often longer than with normal ransomware attacks. The manual process of communicating with the attackers can further delay response time.

For many organizations, downtime is the most expensive part of a ransomware incident. Another negative side effect of a data breach can be damage to your reputation.

Your goal should be to get your systems back to a productive state as soon as possible. The best way to do this is to call in experts who know the ins and outs of Avaddon ransomware to complete the removal and restoration process immediately.

In our experience, a successful ransom payment usually results in getting a working Avaddon decryptor. Decryptor tools do take work to maintain, however, so not all attackers have working tools.

It’s important to know which gang you are dealing with. Some attackers are careful to maintain a good reputation, and always provide working Avaddon decryptors. Others are known to be scammers, and will never provide a decryptor after receiving payment.

The most common attack vector for Avaddon ransomware is phishing.

To our knowledge, there are presently no working free Avaddon decrypt tools for Avaddon ransomware. You can check for free, publicly available decryption tools here.

In most cases, the only way to obtain a working Avaddon decrypt tool is through negotiation with the attackers. Depending on the history of the gang that is behind the hack, it may be possible to get a functional decryption tool by paying the demands of the attackers. Some gangs consistently deliver working ransomware tools. Other hackers can be less reliable, however. Some will demand a second or even third payment after being paid the first time. In some cases, they don’t provide any decryption tool at all or provide a faulty decryption tool. This is why we don’t recommend trying to deal with the gang yourself.

We maintain a database on active ransomware gangs to understand how they operate, the risks of dealing with them, and the probability of success. Knowing the history of a gang can help to negotiate with them more effectively. Using this methodology, we have succeeded in negotiating down ransom demands by as much as 70%.

If the situation is urgent, you can also contact us by phone on our emergency line any time.

The only way to know precisely how much ransomware response will cost is to contact us for a free consultation.

Ransomware response cost varies according to the type of attack, how much data is affected, the number of computers infected, and your local environment (computer performance, servers, operating systems). The response includes removal of the ransomware, negotiations with attackers and transferring payment if necessary, restoring data, patching the vulnerability that led to the attack, and preparing all documentation for legal compliance and insurance claims. The course of action our clients choose also affects the overall cost. 

The minimum cost for small companies generally starts around several thousand euros, including the cost of the ransom. However, if at all possible, we strongly recommend avoiding paying the attackers. Paying the attackers encourages them to harm more people. However, if it is not economically feasible, we handle fully legally compliant payments to attackers. The overall expense depends a lot on the ransom amount demanded, and how successful negotiations are. We maintain a database on ransomware gangs to negotiate more effectively. In some cases, negotiations can result in a significant reduction in the ransom payment.

We have a greater than 98% success rate.

In the case of most of our clients who have cyber insurance, their coverage pays the cost of our services, as well as the ransom, if necessary. 



  1. Professional ransomware response can significantly decrease downtime. We deal with hundreds of cases every year. Through our years of experience, we have developed a streamlined process that brings our clients back online as fast as possible. In the event that a ransom has to be paid, purchasing the necessary cryptocurrency can take days. The process of resolving a ransomware attack without prior experience can take many hours of research. Most of our cases are completely resolved 24-72 hours after we begin the recovery process.

  2. Avoid dealing with criminals and ensure legal compliance. Most companies don’t feel comfortable dealing with cyber-criminals. It can add another layer of stress in emergency. We maintain files on different groups of hackers in order to maximize security and effectiveness of negotiations. We also ensure that all communications and transfers comply with applicable laws and regulations to protect our clients against potential legal problems. 

  3. Cryptocurrency transfers. It is always better to avoid giving into the attacker’s demands. If backups and normal recovery methods fail, however, there may be no other choice. Most ransomware attackers demand payment in Bitcoin. We guide you through the whole process of creating a crypto currency wallet and buying the crypto currency with you. Therefore we have different cooperation partner in order to prepare your wallet and do the transaction as quick and easy as possible for you. 

  4. Ensure data integrity and security. As specialists in the field of ransomware incident response, we are always refining industry best practices for data recovery. We have robust, standardized procedures for backing up encrypted data, restoring data, and removing viruses to ensure that there is no data loss or damage.

  5. Easy Insurance Reporting: All of our clients receive a detailed incident report with all information required by cyber-insurance and for law enforcement purposes. Thankfully, cyber-insurance often covers the cost of cyber-extortion as well as professional ransomware response services. Completing all paperwork correctly from the beginning can speed up the process of filing a claim and recovering lost funds.
  1. Backup, Backup, Backup! In most cases, a fresh and secure backup of data can prevent ransomware attack from succeeding. For this reason, many attackers put in a lot of effort to find and encrypt backups. The best backup will be air-gapped, meaning physically disconnected from your main network. It is also important to have a regular backup schedule with robust security procedures

  2. Install a Next-Gen Antivirus. Next generation anti-virus software combines a classic signature-based antivirus with powerful exploit protection, ransomware protection and endpoint detection and response (EDR). Mcafee, Fireeye, and Sentinel One are all examples of antivirus software with these features. 

  3. Install a Next-Gen Firewall. A Next-Gen-Firewall is also called Unified threat management (UTM) firewall. It adds a layer of security at every entry and exit point of your company data communication. It combines classic network security with intrusion detection, intrusion prevention, gateway antivirus, email filtering and many other features. 

If you can afford it, having staff or hiring a dedicated service to monitor network traffic can also help to detect unusual activity and prevent ransomware attacks. Ransomware attackers usually do a lot of surveillance on a network before attempting a hack. This “reconnaissance” phase has certain tell-tale signs. If you can catch these early, it’s possible to detect the attacker early and deny them access to the network. 

If you get hit by ransomware, a professional ransomware response service can help to identify and patch security gaps.
