How to Respond When a Scammer Gains Access to Your Computer: A Cautionary Tale

In today’s digital age, it’s essential to be vigilant about online security. I recently found myself in a disconcerting situation when my father unwittingly allowed an unknown caller to access his laptop through TeamViewer. The situation unfolded when he received a phone call from someone claiming to be from his Internet Service Provider (ISP). Trusting the representative, he granted them access to his device, only to panic when the screen went black for about four minutes before he cut off the connection.

While I may not be a tech expert, my basic understanding of cybersecurity leads me to believe this could be serious. The prospect of someone potentially installing malicious software or gaining remote control of his computer is alarming. With this in mind, I quickly devised a plan: disconnect the internet, back up important documents, and then perform a full factory reset on his device.

But was this the right approach? After some research and feedback from the community, I realized taking immediate action was crucial. I took the necessary steps to wipe his laptop clean; this included scanning it thoroughly with Malwarebytes, which confirmed that it was free from threats. Although my father was understandably upset about having to reset five years’ worth of passwords, I reassured him that it could have been much worse.

Interestingly, the supposed ISP called again, attempting to initiate the same dubious process. I was right there alongside him this time and firmly told them to leave us alone. This renewed contact could be a silver lining, suggesting that they didn’t manage to extract any sensitive information during the initial breach.

If you ever find yourself in a similar situation, here are a few steps to consider:

Stay Calm: Panicking won’t help. Assess the situation carefully.
Disconnect from the Internet: This will help prevent any further remote access.
Back Up Important Files: If possible, secure any valuable data before taking any drastic measures.
Perform a Full Factory Reset: This is a solid way to ensure that any potential malware is removed from the system.
Change Passwords: Update all passwords, particularly for sensitive accounts, after you’ve secured your computer.
Report the Incident: Inform your ISP and consider reporting the scammer to local authorities.
