Today, the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC), CISA, FBI, NSA, and international partners are releasing Best Practices for Event Logging and Threat Detection. This guide will assist organizations in defining a baseline for event logging to mitigate malicious cyber threats.

The increased prevalence of malicious actors employing living off the land (LOTL) techniques, such as living off the land binaries (LOLBins) and fileless malware, highlights the importance of implementing and maintaining an effective event logging program.

 CISA encourages public and private sector senior information technology (IT) decision makers, operational technology (OT) operators, network administrators, network operators, and critical infrastructure organizations to review the best practices in the guide and implement recommended actions. These actions can help detect malicious activity, behavioral anomalies, and compromised networks, devices, or accounts.

For more information on LOTL techniques, see joint guidance Identifying and Mitigating Living Off the Land Techniques and CISA’s Secure by Design Alert Series.

For more information and guidance on event logging and threat detection, see CISA’s Secure Cloud Business Applications (SCuBA) products, network traffic analysis tool Malcom, and Logging Made Easy.

In recent incidents, CISA has seen malicious cyber actors acquire system configuration files by leveraging available protocols or software on devices, such as abusing the legacy Cisco Smart Install feature. CISA recommends organizations disable Smart Install and review NSA’s Smart Install Protocol Misuse advisory and Network Infrastructure Security Guide for configuration guidance. 

CISA also continues to see weak password types used on Cisco network devices. A Cisco password type is the type of algorithm used to secure a Cisco device’s password within a system configuration file. The use of weak password types enables password cracking attacks. Once access is gained a threat actor would be able to access system configuration files easily. Access to these configuration files and system passwords can enable malicious cyber actors to compromise victim networks. Organizations must ensure all passwords on network devices are stored using a sufficient level of protection. 

CISA recommends type 8 password protection for all Cisco devices to protect passwords within configuration files. Type 8 password protection is more secure than other password types and approved by NIST. CISA urges organizations to review NSA’s Cisco Password Types: Best Practices guide for more information and follow the best practices for securing administrator accounts and passwords:  

• Properly store passwords with a strong hashing algorithm.  

• Do not reuse passwords across systems.  

• Assign passwords that are strong and complex.  

• Do not use group accounts that do not provide accountability. 

CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.

• CVE-2024-36971 Android Kernel Remote Code Execution Vulnerability
• CVE-2024-32113 Apache OFBiz Path Traversal Vulnerability

These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise.

Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise.

Today, CISA—in partnership with the Federal Bureau of Investigation (FBI)—released an update to joint Cybersecurity Advisory #StopRansomware: Royal Ransomware, #StopRansomware: BlackSuit (Royal) Ransomware. The updated advisory provides network defenders with recent and historically observed tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) associated with BlackSuit and legacy Royal activity. FBI investigations identified these TTPs and IOCs as recently as July 2024.

BlackSuit ransomware attacks have spread across numerous critical infrastructure sectors including, but not limited to, commercial facilities, healthcare and public health, government facilities, and critical manufacturing.

CISA encourages network defenders to review the updated advisory and apply the recommended mitigations. See #StopRansomware for additional guidance on ransomware protection, detection, and response. Visit CISA’s Cross-Sector Cybersecurity Performance Goals for more information on the CPGs, including additional recommended baseline protections.

CISA encourages software manufacturers to take ownership of improving the security outcomes of their customers by applying secure by design tactics. For more information on secure by design, see CISA’s Secure by Design webpage and joint guide Shifting the Balance of Cybersecurity Risk: Principles and Approaches for Secure by Design Software.

Today, CISA and the Federal Bureau of Investigation (FBI) have released Secure by Demand Guide: How Software Customers Can Drive a Secure Technology Ecosystem to help organizations drive a secure technology ecosystem by ensuring their software manufacturers prioritize secure technology from the start.

An organization’s acquisition staff often has a general understanding of the core cybersecurity requirements for a particular technology acquisition. However, they frequently don’t assess whether a given supplier has practices and policies in place to ensure that security is a core consideration from the earliest stages of the product development lifecycle.

This guide provides organizations with questions to ask when buying software, considerations to integrate product security into various stages of the procurement lifecycle, and resources to assess product security maturity in line with secure by design principles. 

This guide compliments the “Software Acquisition Guide for Government Enterprise Consumers: Software Assurance in the Cyber-Supply Chain Risk Management (C-SCRM) Lifecycle” that was recently published.

CISA encourages organizations to review both the Secure by Demand Guide and Software Acquisition Guide and implement recommended actions.

CISA released one Industrial Control Systems (ICS) advisory on August 6, 2024. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.
