Introduction to Ololo Ransomware
Ololo ransomware is a malicious software identified as a variant of the MedusaLocker family. It primarily targets QNAP and other Network-Attached Storage (NAS) devices, encrypting files and demanding ransom payments for decryption. The ransomware appends the “.ololo” extension to encrypted files and leaves a ransom note named “RETURN_DATA.html”.

File Encryption Process
Upon infection, Ololo ransomware scans the system for files to encrypt. It utilizes a combination of RSA and AES encryption algorithms to lock files, appending the “.ololo” extension to each encrypted file (e.g., “document.docx” becomes “document.docx.ololo”). The ransomware also drops a ransom note named “RETURN_DATA.html” in affected directories.
Ransom Note Details
The ransom note, “RETURN_DATA.html”, contains the following message:
Your personal ID:

- Email Attachments: Malicious emails containing infected attachments such as MS Office documents, PDFs, or executable files.
- Malicious Advertisements: Ads leading to compromised websites that host the ransomware.
- Pirated Software: Downloading and installing pirated or cracked software from unreliable sources.
- P2P Networks: Sharing infected files through peer-to-peer networks.
- Exploiting Vulnerabilities: Taking advantage of unpatched software or operating system vulnerabilities.
Detection and Removal
Several antivirus and anti-malware programs can detect Ololo ransomware. Detection names include:
- Avast: Win64:MalwareX-gen [Ransom]
- Combo Cleaner: Gen:Variant.Tedy.700016
- ESET-NOD32: A Variant Of Win64/Filecoder.MedusaLocker.A
- Kaspersky: HEUR:Trojan-Ransom.Win32.Generic
- Microsoft: Ransom:Win64/MedusaLocker.MZT!MTB
To remove Ololo ransomware, it is recommended to use reputable antivirus software to perform a full system scan and eliminate the infection.
Preventive Measures
To protect against Ololo ransomware and similar threats:
- Regular Backups: Maintain up-to-date backups of important data on external drives or cloud storage.
- Software Updates: Keep operating systems and all software applications updated with the latest security patches.
- Email Vigilance: Be cautious with email attachments and links, especially from unknown senders.
- Avoid Pirated Software: Download software only from official and trusted sources.
- Security Software: Use comprehensive antivirus and anti-malware solutions to detect and prevent threats.
Impact on QNAP and NAS Devices
Ololo ransomware specifically targets QNAP and other NAS devices, exploiting vulnerabilities to gain unauthorized access. Once infected, the ransomware encrypts files stored on these devices, rendering them inaccessible without the decryption key. Users are advised to secure their NAS devices by disabling unnecessary services, updating firmware, and avoiding direct exposure to the internet.
