.oled File Virus – Distribution
For it’s distribution, Oled ransomware may use spam e-mails that aim to spread it’s malicious executable that drops the payload of the ransomware once opened. These malicious executable files may be loaders or droppers and may be either uploaded on websites or sent out via spam.
One of the spam methods which may be associated with Oled ransomware infections, is via e-mail.

Usually most e-mails aim to resemble legitimate companies such as PayPal or other entities.
.oled Ransomware – Analysis
Oled ransomware virus is a part of the BTCWare ransomware family, meaning it may exhibit similar behavior to other viruses from the family, like the .onyon ransomware.
After infection has taken place, the ransomware virus may begin to exhibit different types of activities, the first of which is to drop the malicious files related to the virus in various Windows folders. These files may be located in multiple different Windows folders, such as:
- %AppData%
- %Roaming%
- %Local%
- %LocalLow%
- %Temp%
After the malicious files of the Oled ransomware are dropped on the infected computer, the malware may modify the registry keys on the infected computer, more specifically targeting the Run and RunOnce registry keys. After doing so, the virus may also delete the shadow volume copies on the infected computer. These shadow copies are an option to recover files and Oled ransomware may execute the vssadmin and other commands in order to delete them:
→ process call create “cmd.exe /c
vssadmin.exe delete shadows /all /quiet
bcdedit.exe /set {default} recoveryenabled no
bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures
After this has happened, the Oled ransomware infection may also drop it’s ransom note, which has the following message to victims:
The ransom note is almost identical to the ransom note set by OnyonLock ransomware:
Oled Ransomware – Encryption Process
