A Cautionary Tale: Battling the DJVU/STOP Ransomware

In today’s digital landscape, the threat of ransomware looms larger than ever. Recently, I encountered a distressing experience that highlights the importance of being cautious with software sources, particularly when it comes to downloading plugins and applications.

The Incident

While exploring new FL Studio plugins, I accidentally downloaded a file from a less-than-reputable website. After executing an .exe file, my computer was swiftly compromised by a variant of ransomware known as DJVU/STOP. This malicious software encrypted all my personal files, leaving them with the .SGHL extension, rendering them inaccessible.

Upon inspecting the aftermath, I found a text file left by the attackers. It contained a chilling message:

ATTENTION!

Don’t worry, recovering your files is possible! Unfortunately, they’ve used robust encryption techniques and a unique key for your data. The only way to regain access is by purchasing a decrypting tool along with a unique key specifically for your files.

To entice victims, they offer to decrypt one file for free—provided it doesn’t include any sensitive information. In their message, they included a link to a video overview of the decryption tool, which I caution you against clicking.

The ransom for the private key and decryption software? A staggering $980, or $490 if contacted within the first 72 hours for a supposed discount. They assured that without payment, file recovery was impossible and advised checking spam folders if no response was received.

Seeking Help

At this point, I felt completely helpless. My files—photos, documents, and other essential data—were at the mercy of these criminals. I wondered: in addition to encrypting my files, had they copied them elsewhere? Would I ever see my data again?

I reached out to friends and online communities for advice, and the support I received was incredibly heartwarming. Many shared their thoughts and experiences with ransomware, and I’m grateful for every piece of feedback.

Preventive Measures Moving Forward

This incident served as a critical reminder of the importance of cybersecurity. Here are a few tips to help others avoid a similar fate:

1. Vet Your Sources: Always download software from trusted, reputable sites. Avoid unofficial or questionable sources.

2. Back Up Your Data: Regularly back up your important files on external drives or cloud storage. Having backups can save you from a devastating loss in the event of
