Unwelcome Intruders: Dealing with Mysterious Remote Access to Your Computer

In today’s digital age, the concept of remote access can be both a beneficial tool and a potential nightmare. As an IT support professional, I recently found myself grappling with a frightening case of unknown remote access to my system that left me puzzled and concerned. Here’s a detailed account of my experience, the steps I took to address the situation, and the lessons learned along the way.

The Incident

It all began when I noticed that my computer—specifically my Firefox browser—was being remotely controlled. The intruder appeared to have gained access without my consent and executed a series of actions that were beyond my control. Here’s what transpired:

1. The intruder opened a new tab in Firefox, which was already active.
2. They attempted to search for “Google” using the address bar but misspelled it at first.
3. Following that, they searched for the name of a cryptocurrency game.

At this point, alarm bells went off in my head, and I promptly disconnected my network cable to prevent further access. Here’s a list of immediate measures I took to fortify my system:

• Disabled remote access to my PC.
• Uninstalled AnyDesk, which I had been using for work-related tasks.
• Conducted thorough scans with Malwarebytes and its rootkit scanner, which returned no threats.
• Adjusted the local security policy to block network connections.
• Removed recently installed applications such as ClipClip and Winamp.

It’s worth mentioning that my Windows operating system was fully updated, and I was using Windows Defender as my antivirus solution.

Questions on My Mind

After taking these precautions, two questions lingered in my mind: How did this happen? and Why did the intruder choose to search for that particular game? While pinpointing the “how” remained elusive, the “why” intrigued me further. What motivated someone to navigate to a specific cryptocurrency game on my computer?

Despite my intentions to reinstall Windows 10 for added security, I hoped to gather more insights before taking that drastic step.

Community Insights and Updates

After sharing my experiences and seeking advice, I removed the name of the game from my post to avoid any unwanted attention. The feedback I received from the community was incredibly helpful, but unfortunately, I could not identify a definitive cause for the intrusion. It appeared that my vulnerability could have stemmed from a browser extension,
