Simplicity, Harmony, and Opportunity: Rapid7 Threat Report Q3 2017

John Archibald Wheeler, the theoretical physicist who first coined the term “wormhole” (and therefore brought us Deep Space 9) once listed Albert Einstein’s Three Rules of Work: > Out of clutter find simplicity; from discord find harmony; in the middle of difficulty lies opportunity. These rules seemed fitting for our third quarter threat report []. Q3 brought us plenty of clutter, discord, and difficulty, but in this threat repo

The BadRabbit Ransomware Attack: What You Need To Know

What’s Up? Rapid7 has been tracking reports of an expanding ransomware campaign dubbed BadRabbit. Russian news outlets and other organizations across Europe have reported being victims of this malware and the “outbreak” is continuing to spread.

Compromised Credentials Have a High ROI for Attackers

Given that detecting the use of compromised credentials is at the core of user behavior analytics', and InsightIDR's, focus, I want to explain why compromised credentials are so valuable to attackers. To effectively understand any attacker tools and techniques, we have to put them into the context of their challenges and goals the same way you would a business, or supply chain of businesses. Accordingly, I will use some common microeconomics terms to explain. Phishing has a high expected return

Attackers Take Advantage Of The Options You Give Them - Malware vs. Credentials

When InsightIDR was purpose-built to detect compromised credentials in the first months of 2014, we did so because we identified a significant gap in detection solutions currently available to security teams. The 2014 Verizon DBIR just happened to subsequently quantify the size of this gap (and it has repeated in 2015 and 2016). User behavior analytics, as an industry, emerged to cover this gap in SIEM and other solutions. This does not mean that malware is not heavily used in attacks today, but

Hammertoss Demonstrates Need for Applying Attacker Knowledge to Behavior Analytics

A recent report on a new type of malware dubbed “Hammertoss []” highlights the importance of applying knowledge of attacker methodologies to behavior analytics. As an industry, we get very fixated on the latest intruder tools. The risk here is that we can't see the forest for the trees. To effectively detect intruders, we must look at the entire attack chain and the methods attackers will always use to complete their mi

Rapid7 UserInsight Brings User Context to Palo Alto WildFire Alerts

According to the Ponemon Institute's 2014 Industry Report, 74% of security professionals claim incident investigation solutions lack integration with existing security products. UserInsight, our intruder analytics solution, now integrates with Palo Alto WildFire to provide user context and investigative tools to their advanced malware alerts. What does user context mean? For incident alerts, monitoring solutions often provide the IP addresses or assets affected. However, as users connect to the
