CISA and FBI Warn of Valentine’s Day Scams

Both the Cybersecurity and Infrastructure Security Agency (CISA) and the FBI have released advisories warning of internet romance scams on the occasion of Valentine’s Day. The FBI’s advisory explains well-rehearsed criminals search dating sites, apps, chat rooms, and other social media networking sites attempting to build “relationships” for the sole purpose of getting your money or your personally identifiable information.

Microsoft Windows Privilege Escalation Vulnerability

As part of its regular patch Tuesday release, Microsoft has announced an escalation of privileges vulnerability (CVE-2021-1732) in Microsoft Win32k. A local attacker can exploit this vulnerability to take control of an affected system. Microsoft has stated that Windows 10 and Windows Server 2019 are affected by this vulnerability. Microsoft has also reported that this vulnerability has

The Top Consumer Frauds of 2020

The Federal Trade Commission (FTC) reflects on the top consumer frauds for 2020, noting that overall it was a busy year. According to the FTC, last year it received more than 2.2 million reports about fraud, with people collectively indicating they had lost nearly $3.3 billion. The top fraud of 2020 was imposter scams, with scammers showed up wearing many different hats – from that of a government official, to a known business, to a dear family member or friend.

Safer Internet Day – Together for a Better Internet

Today is Safer Internet Day. With a theme once again of "Together for a Better Internet,” the organizers and supporters of this initiative call upon all stakeholders to join together to make the internet a safer and better place for all. While much of the focus of Safer Internet Day is on children and young people, this initiative still provides information and resources that can be useful for others, including representatives of organizations and industries.

Malicious Actor Compromises U.S. Water Treatment Plant, Changes Chemical Level

Today officials in Florida announced that late last week an unknown malicious actor infiltrated a water treatment plant in the city of Oldsmar and made changes to chemical levels in the treatment process. Fortunately this activity was quickly observed by a plant operator and reversed. Officials indicated that the public was never in danger due to the operator's quick action as well as to other measures that would have prevented the release of the water into the distribution system.

OT/ICS Security – Understanding, Differentiating, and Reporting OT Infrastructure Compromises

In the interest of incident reporting it is important to be able to identify and differentiate types of incidents being reported. It is also important to be able to understand the difference between an actual attack and an unintentional incident that may have attack-like consequences. Given cross-sector dependencies, some water and wastewater utilities closely track and apply NERC CIP regulations even though they aren’t required. NERC CIP 008-6 became mandatory on January 1, 2021 and requires bulk power system utilities to report attempts to compromise their infrastructure and operations.

OT/ICS Security – Consequence-driven Cyber-informed Engineering (CCE)

In another reference to WaterISAC's 15 Cybersecurity Fundamentals for Water and Wastewater Utilities, you may recall this topic being discussed at #6 Install Independent Cyber-Physical Safety Systems. Consequence-driven Cyber-informed Engineering (CCE) is an advanced topic for critical infrastructure organizations, but one that shouldn't be overlooked.

OT/ICS Security – Network Segmentation and Asset Management

As stated in #3 Minimize Control System Exposure in WaterISAC's 15 Cybersecurity Fundamentals for Water and Wastewater Utilities, critical infrastructure site assessments performed by CISA for the water and wastewater sector cite the most commonly identified network weakness is a lack of appropriate boundary protection controls. Furthermore, as Armis reminds, per NIST, network segmentation and segregation is one of the most effective architectural concepts that an organization can implement to protect ICS.
