A 27-year-old from Hot Springs, Arkansas, was for a time very popular among the world’s cyber criminals, thanks to a malicious piece of software he created called NanoCore Remote Access Trojan (RAT). That malware allowed hackers to steal sensitive information from victims’ computers, including account numbers and passwords, and even allowed them to secretly activate the webcams of infected computers to spy on unsuspecting victims.

The NanoCore RAT has the ability to control a victim’s computer.  This type of malware—a Remote Access Trojan (RAT)—is all the more insidious because in most cases victims have no idea their computers have been compromised. According to court documents, NanoCore RAT was used to infect and attempt to infect more than 100,000 computers.

He didn’t stop with NanoCore RAT. He also developed and profited from Net Seal, a fee-based licensing software that he and his customers used to distribute NanoCore RAT and other malware.  He was arrested in February 2017 and charged with aiding and abetting computer intrusions. He pleaded guilty, admitting that he intended his products to be used maliciously. In February 2018, a federal judge sentenced him to 33 months in prison.
