FBI Expects a Rise in Scams Involving Cryptocurrency Related to COVID-19 Pandemic

The FBI advises its partners to be on the lookout for an increase in the following cryptocurrency fraud schemes related to COVID-19. These schemes may include blackmail attempts, work from home scams, paying for non-existent treatments or equipment, and investment scams. Although each of these scams has its own twist, they share the commonalities of attempting to capitalize on the fear and uncertainty during the current pandemic to steal money and launder it through the cryptocurrency ecosystem.

FBI Warns of Advance Fee and BEC Schemes Related to PPE and Supplies Procurement during COVID-19 Pandemic

The FBI has issued an industry alert warning of rapidly emerging advance fee and business email compromise (BEC) schemes related to procurement of personal protective equipment (PPE) and other equipment in short supply during the current COVID-19 pandemic. The FBI recently became aware of multiple incidents of government agencies, attempting to procure such equipment, wiring transferred funds to fraudulent sellers in advance of receiving the items. In one case, an individual claimed to represent an entity with which the purchasing agency had an existing business relationship.

Adversaries Living off the ICS/OT Land and How to Detect Them

“Living off the land” is a phrase adopted to describe adversary behavior of using built-in system tools in an attempt to blend in or hide in plain sight with expected system/network activity. The practice typically involves IT-based tools and tactics, but industrial cybersecurity firm Dragos reviews the relevance or living off the land for ICS/OT environments. Even advanced ICS-focused (and skilled) threat groups use IT-based system tools such as PowerShell to gain initial access before traversing ineffective network segmentation to compromise ICS/OT networks.

Security Awareness – A Few of the Latest Coronavirus Related Scams

Even during this challenging time, there is no question that cyber attack ploys are the same. Threat actors constantly leverage disasters in their campaigns; however, the specific themes and lures abusing coronavirus news and information across various attack techniques continues unabated. Attackers are not letting up, and we must not grow weary in keeping our remote workers aware of the scams using coronavirus that are intended to trick them into clicking on a malicious link or opening a weaponized document.

KUKA.Sim Pro (ICSA-20-098-05)

CISA has published an advisory on an improper enforcement of message integrity during transmission in a communication channel vulnerability in Kuka.Sim Pro. Version 3.1 is affected. Successful exploitation of this vulnerability could result in a loss of integrity in external 3D models fetched from remote servers. When tested on real machines, this effect is unpredictable. KUKA recommends upgrading KUKA.Sim Pro to Version 3.1.2 or above to mitigate this vulnerability. CISA also recommends a series of measures to mitigate the vulnerability.
