ASD’s ACSC, CISA, FBI, and NSA, with the support of International Partners Release Best Practices for Event Logging and Threat Detection
Aug 21, 2024
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.

Best Practices for Cisco Device Configuration
Aug 8, 2024
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.

Royal Ransomware Actors Rebrand as “BlackSuit,” FBI and CISA Release Update to Advisory
Aug 7, 2024
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.

CISA Releases Secure by Demand Guidance
Aug 6, 2024
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.
