Ransomware got its start in 1989. Back then, it was relatively ineffective. That's changing, which is bad news for us.
One of my neighbors recently experienced ransomware first hand. Up until then, he had no idea it existed. Because of that, it seems important to revisit extortion malware, explain exactly what it is, and how to avoid it.
Ransomware made its debut with a trojan called PC Cyborg, the brainchild of Dr. Joseph Popp. The extortion begins with a vulnerable computer becoming infected. Once settled in, the malware hides all folders and encrypts file names on the C: drive. Next, a dialog box opens, proclaiming the victim needs to send PC Cyborg Corporation $189 US, because the license had expired.
