Usam Ransomware

Frustrated with Ransomware

What is Usam Ransomware?

Usam ransomware is a deadly cryptovirus which falls under the Djvu ransomware family. The virus threat is high as it can even initiate more deadly Trojan dangers. This malicious program locks the victim’s files upon infiltrating the computer. Then the orchestrators demand money in exchange for the decryption key. The cybercriminals behind this virus are infamous for launching attacks using various malicious software that falls under the Djvu family. The criminals have released over 230 virus versions with the Usam being the latest version.

Usam ransomware was first reported in the middle of June 2020 and the malware has continued to grow its popularity among the Windows platform users. The distribution of this malicious program is often carried out through dodgy techniques such as software cracks, unsecured RDPs, as well as keygens. When an individual initiates the ransomware payload, the malicious programs begin working immediately, encrypting files, mainly targeting music, videos, photos, as well as documents and many more. When the file is encrypted, a .usam extension is added, completing the victim’s restriction to access their files.

How to Remove Usam Ransomware

The sad truth is that at this moment, there is no way of decrypting Usam encrypted files without having to pay. Even the famous STOPdecryptor, which is available to anyone online, is not able to decrypt files locked by Usam. STOPdecryptor is kind of outdated as it can only decrypt Djvu versions that were released no later than 2019 autumn.

According to the readme text file dropped on the victim’s computer once the encryption of personal files is completed, the user must transfer a Bitcoin fee equivalent to $490 within 72-hours. Details of the address to transfer the crypto fee can be obtained by chatting with one of the cybercriminals’ representatives on email or If the fee is not paid within the stipulated timeframe, the victim will be forced to pay a revised ransom amount of $980.

Although paying the ransomware fee may seem to be the only way of getting access to your files again, we advise against it. Why? For starters, these are criminals who rely on extorting innocent people for a living. Therefore, there is no honor among them, which means there is no guarantee that you will get your files decrypted. Even if you do, there is also no guarantee that they will leave you alone forever. Once you give in, you become an easy target for them. Rather lose the files without incurring any financial losses.

What Can Usam Ransomware Do?

As soon as you discover that you have been attacked by Usam ransomware, removing the virus immediately should be your immediate course of action. Keeping the virus in your system for a long time might corrupt some of your system files, further sinking the roots of the issue. Moreover, Usam is part of a gang, meaning chances of it inviting its friends for a permanent visit are high. However, regardless of the timeframe that the Usam virus might have spent in your system, you will need a deep system cleaning tool. For starters, for the virus to evade detection, it must first make some changes to the system. After that, it will be possible for it to launch the encryption tool without detection.

Initially, Usam ransomware plants malicious entries in %AppData%, %User% or %Temp% directories. It then launches the command with administrator privileges, then deletes Shadow Volume Copies and deactivate the system’s antivirus software. Finally, it then downloads Trojan Azorult, which is a data-stealing secondary payload. The changes don’t end there as they are not definite. Therefore, the longer the virus stays, the harder it will be to get rid of it permanently.

When Usam has successfully infiltrated your computer, there will be an entire system lockdown of files. The information note will then be served under the _readme.txt file and it will read as follows:


Don’t worry, you can return all your files!
