Dealing with Ransomware: A Teacher’s Laptop Infection
Recently, an unfortunate situation arose involving a teacher’s laptop that became infected with ransomware, resulting in all his files being converted to the “.nobu” extension. This scenario unfolded after he downloaded several PDFs from an untrustworthy website, which led to numerous unidentified programs cluttering his Task Manager alongside the file encryption issue.
Initial Steps Taken
In light of the urgency of the situation, I quickly ran Malwarebytes on his machine. Since there were no backups of the files, restoring the system to a previous point was not an option. This left us searching for ways to remove the “.nobu” extension from all affected files.
Critical Files Compromised
As I delved further into the matter, it became evident that some of his essential files, particularly those related to Eagle software for PCB design, were also infected. The ransomware had severely impacted the program, rendering it inoperable.
The Encryption Challenge
In my attempts to resolve the issue, I discovered that the encryption might require an online key. I also tested Emsisoft; however, it did not yield positive results. The situation felt increasingly daunting, but I reached out to the online community for assistance.
Community Support
I want to extend my heartfelt gratitude to everyone who offered their help and guidance. It was heartening to witness such an outpouring of support. The teacher, who has a background in electronics and works in the IT field, felt encouraged by the response. He often uses the laptop for PCB design, C programming, and Arduino projects, making this situation even more stressful for him.
Visual Evidence of the Issue
To better illustrate the predicament, I’ve attached some images. Unfortunately, I encountered difficulties capturing screenshots, as Microsoft Paint and the print screen function weren’t cooperating:
Next Steps
Before considering the drastic measure of formatting the laptop, I plan to explore various decryption software options. I remain hopeful that one of these tools will provide a solution, allowing us to restore the valuable files that are critical to his work.
