Building a Digital Defense Using Virtual Private Networks

The FBI’s Portland, Oregon office has published an advisory discussing the use of virtual private networks, or VPNs. For those who use public WiFi networks for business or personal computing, VPNs are an incredibly important tool as they render traffic that could otherwise be intercepted by a third party – potentially a malicious actor – as unreadable. Given that there are many different types of VPNs on the market, the FBI offers a series of tips to assist in decisions about which one to choose.

CISA Malware Analysis Report on Recent North Korean Activity: “HOPLIGHT”

This activity, referred to as “HOPLIGHT,” involves Trojan malware variants. The MAR includes malware descriptions, suggested response actions, and recommended mitigation techniques. Users or administrators should flag activity associated with the malware and report the activity to CISA or the FBI Cyber Watch (CyWatch) and give the activity the highest priority for enhanced mitigation.

Cybersecurity Best Practices for Operating Commercial Unmanned Aircraft Systems

The DHS Cybersecurity and Infrastructure Agency (CISA) has published a document on cybersecurity best practices for operating commercial unmanned aircraft systems (UASs). In the document, CISA explains that while UASs offer benefits, they can also pose cybersecurity risks that necessitate caution on the part of operators. The document is intended to assist an organization with standing up or securing an existing program and is meant for information technology managers and personnel involved in UAS operations.

Incident Response Ransomware: Part One

TrustedSec has published the first blog in what it says will become a three-part series on responding to a ransomware incident. Part one provides an introduction into what ransomware is, how it works, and how it spreads to systems within an organization. It also describes different types of ransomware and variations of ransomware tactics. While part two in this series will go more into the attack kill chain, this first segment provides an overview of the sequence of events that occur during infection. Part two will also discuss more of the ways to detect, protect, and prevent ransomware.
