Wilton School is Victim of Phishing and Spoofing - October 2, 2019

About two weeks ago, approximately 15 high school students and parents from Wilton High School reported getting suspicious and threatening emails at their school email accounts. The emails appeared to be coming from themselves, and had the same email address as their accounts. This is known as “spoofing,” when a hacker impersonates another device or user on a network. The sender of the email then indicated they had taken over the victim’s email and demanded payment in Bitcoin, a cryptocurrency, to restore the victim’s contact lists.

The good thing is no one fell for the bait and no identities and data were breached.

NSI Catching Cryptoviruses in January 2019

In the first few months of 2019, we've observed a sudden increase in the volume of calls and emails from clients regarding suspicious emails. Tammy, Director of Client Services, said "A client just recently had a new employee who hadn’t taken the security training yet, clicked on an attachment in an email that caused them to get a crypto virus. We were able to remediate relatively quickly but it could have been a catastrophe. Same customer uses RDS rather than VPN against our recommendation to connect to their server. This leaves a port opened that can allow an intruder to brute force their RDP server. The effect of this vulnerability allowed for them to overload the resources of the RDS server. Again we were able to remediate quickly so it didn’t cause too much downtime."
