CISA and Partners Release Advisory on Russian SVR-affiliated Cyber Actors Exploiting CVE-2023-42793

Today, CISA—along with the U.S. Federal Bureau of Investigation (FBI), National Security Agency (NSA), Polish Military Counterintelligence Service (SKW), CERT Polska (CERT.PL), and the UK’s National Cyber Security Centre (NCSC)—released a joint Cybersecurity Advisory (CSA), Russian Foreign Intelligence Service (SVR) Exploiting JetBrains TeamCity CVE Globally.

Since September 2023, Russian Foreign Intelligence Service (SVR)-affiliated cyber actors (also known as Advanced Persistent Threat 29 (APT 29), the Dukes, CozyBear, and NOBELIUM/Midnight Blizzard) have been targeting servers hosting JetBrains TeamCity software that ultimately enabled them to bypass authorization and conduct arbitrary code execution on the compromised server. The joint CSA provides information on the SVR’s most recent compromise, actionable indicators of compromise (IOCs), and SIGMA and YARA rules.

The authoring agencies encourage network defenders and organizations review the joint CSA for recommended mitigations and rules. For more information on affiliated advanced persistent threats, see CISA’s Advanced Persistent Threats and Nation-State Actors and Russia Cyber Threat Overview and Advisories webpages.

CISA Releases Joint Guide for Software Manufacturers: The Case for Memory Safe Roadmaps

Today, as part of the Secure by Design campaign, CISA published The Case for Memory Safe Roadmaps: Why Both C-Suite Executives and Technical Experts Need to Take Memory Safe Coding Seriously in collaboration with the following partners:

  • United States National Security Agency
  • United States Federal Bureau of Investigation
  • Australian Signals Directorate’s Australian Cyber Security Centre
  • Canadian Centre for Cyber Security
  • United Kingdom National Cyber Security Centre
  • New Zealand National Cyber Security Centre
  • Computer Emergency Response Team New Zealand

Malicious cyber actors routinely exploit memory safety vulnerabilities, which are common coding errors and the most prevalent type of disclosed software vulnerability. Preventing and responding to these vulnerabilities cost both software manufacturers and their customer organizations significant time and resources.

The Case for Memory Safe Roadmaps details how software manufacturers can transition to memory safe programming languages (MSLs) to eliminate memory safety vulnerabilities. The guidance provides manufacturers steps for creating and publishing memory safe roadmaps that will show their customers how they are owning security outcomes, embracing radical transparency, and taking a top-down approach to developing secure products—key Secure by Design tenets.

CISA and our partners urge C-suite and technical experts at software manufacturers to read this guidance and implement memory safe roadmaps to eliminate memory safety vulnerabilities from their product.
