Cybersecurity Blog: The Cyber Scene is evolving, are you?

Overview

On March 15 2018, the Department of Homeland Security (DHS) and Federal Bureau of Investigation (FBI) released a joint Technical Alert (TA) – TA18-074A providing information on Russian government actions targeting U.S. critical infrastructure organizations including energy, nuclear, water, aviation and critical manufacturing sectors. The TA includes the Indicators of Compromise (IOCs) and technical details on the tactics, techniques, and procedures (TTPs) used by Russian government cyber actors on compromised victim networks.

Spear Phishing
noun

The fraudulent practice of sending emails ostensibly from a known or trusted sender in order to induce targeted individuals to reveal confidential information.
"spear phishing represents a serious threat for every industry"

How does this serious threat effect your organization? We’ve built a detailed analysis of how one adversary takes a very personal approach to the classic supply chain attack. It analyzes the attack end to end, using the Cyber Kill Chain® analysis framework, including review of how a targeted email was delivered and weaponized.

Note: All names are fictional, and any resemblance to real people or companies is unintentional.

With their proprietary control protocols and use of specialized hardware and software, early industrial control systems (ICS) had little resemblance to traditional information technology (IT) systems.  However, today’s ICS environments are using industry standard computers, operating systems (OS) and network protocols, putting them at risk of cybersecurity vulnerabilities and incidents. The increased use of wireless networking further acerbates the security issue.

Struggling with internal security teams that are short-staffed, overworked, and underskilled, today’s CISOs are turning to information security consulting providers for needed expertise. But who should they turn to in a market full of choices?

At the Black Hat 2017 conference in Las Vegas, Leidos gave a sneak peek at a new product for critical infrastructure customers—Arena Asset Visibility and Insights (AVI). The product’s concept was driven by interactions with customers who shared concerns over the lack of situational awareness and visibility into their industrial control systems (ICS) network. While most have a wealth of tools and processes to aggressively monitor and respond to threats and security incidents to their Enterprise IT network, their Operations (OT) side is typically only monitored up to the edge of the IT/OT firewall. For the Security Analysts in the SOC, managers who act as a liaison between the plants, corporate IT, and the plant operation managers, OT awareness is minimal.

The cyber-attack on Ukraine power centers last December — an event that took 30 substations offline and left more than 230,000 residents without power — was a rude awakening for power generation plants and distribution centers around the world. Despite being well-segmented from the control center business networks with robust firewalls — notably more secure than some U.S. operations — the network was still breached.

Insider crimes are a very real and costly problem for companies—often more costly than high profile cyberattacks. Despite continued investments in security measures to control and monitor access to sensitive data, more organizations feel vulnerable to breaches caused by insiders. In fact, according to a recent survey of security professionals conducted by LinkedIn’s Information Security Community and Crowd Research Partners, 74% of respondents say their organizations are vulnerable to insider threats, and 56% say insider threat incidents have become more frequent in their organization in the last 12 months.

An evolving threat landscape, persistent adversaries, and a shortage of talent and skills are some of the reasons security teams struggle to successfully defend their organizations. However, the biggest roadblock to a successful defense is often self-inflicted.
