It’s Difficult to Paint the OT/ICS Threat Landscape Picture when Incidents aren’t Reported

While there seems to be interest in the OT/ICS cyber threat landscape, it’s truly a challenge to paint an accurate picture when organizations don’t report incidents – it’s like trying to paint a beautiful sunset with only black and white. Nonetheless, some organizations develop surveys with questions believed to capture the perceived issues and challenges in order to at least cover the broad strokes. The latest such survey report comes from the SANS Institute, for which 480 of your OT/ICS peers have spoken – A SANS 2021 Survey: OT/ICS Cybersecurity.

ProxyToken – the Most Recent Microsoft Exchange Vulnerability

Another vulnerability associated with Microsoft Exchange Server has been disclosed. The flaw, dubbed “ProxyToken,” allows remote attackers to bypass authentication and alter an Exchange email server’s backend configuration. This vulnerability could be exploited by a threat actor to copy all emails sent to a specified target account and then forward those emails to a separate account controlled by the attacker.

Cybersecurity Hygiene – Password Re-use, not Just for Users

Users are not the only ones to suffer from password re-use across multiple sites, services, or devices. Unfortunately, many system administrators use the same passwords for local administrator access across all workstations for ease of technical support. But what’s good for the sysadmin, is also good for the threat actor who gains access to password hashes. Pen Test Partners (PTP) briefly discusses the issues with admin password re-use and suggests a more secure solution than using the same local admin password across all workstations.

FBI FLASH: Indicators of Compromise Associated with Hive Ransomware

The FBI has published another TLP:WHITE FLASH providing indicators of compromise associated with “Hive” ransomware. The Flash indicates that Hive ransomware, which was first discovered in June 2021 and likely operates as an affiliate-based ransomware campaign, primarily employs phishing tactics and remote desktop protocol (RDP) attacks to infiltrate a company’s network. After compromising a network, attackers exfiltrate data and encrypt files on the network before leaving a ransom note with further instructions.
