Today, the Australian Signals Directorate Australian Cyber Security Centre (ASD ACSC), the Cybersecurity and Infrastructure Security Agency (CISA), and other U.S. and international partners released the joint guide Detecting and Mitigating Active Directory Compromises. This guide informs organizations of recommended strategies to mitigate common techniques used by malicious actors to compromise Active Directory.

Active Directory is the most widely used authentication and authorization solution in enterprise information technology (IT) networks globally. Malicious actors routinely target Active Directory as part of efforts to compromise enterprise IT networks by escalating privileges and targeting the highest confidential user objects.  

Responding to and recovering from malicious activity involving Active Directory can be consuming, costly, and disruptive. CISA encourages organizations review the guidance and implement the recommended mitigations to improve Active Directory security.

CISA continues to respond to active exploitation of internet-accessible operational technology (OT) and industrial control systems (ICS) devices, including those in the Water and Wastewater Systems (WWS) Sector. Exposed and vulnerable OT/ICS systems may allow cyber threat actors to use default credentials, conduct brute force attacks, or use other unsophisticated methods to access these devices and cause harm.   

CISA urges OT/ICS operators in critical infrastructure sectors to apply the recommendations listed in Defending OT Operations Against Ongoing Pro-Russia Hacktivist Activity to defend against this activity.

As Hurricane Helene approaches, CISA urges users to remain on alert for potential malicious cyber activity. Fraudulent emails and social media messages—often containing malicious links or attachments—are common after major natural disasters. Exercise caution in handling emails with hurricane-related subject lines, attachments, or hyperlinks. In addition, be wary of social media pleas, texts, or door-to-door solicitations relating to severe weather events. 

CISA encourages users to review the following resources to avoid falling victim to malicious cyber activity: 

• Federal Trade Commission’s Staying Alert to Disaster-related Scams and Before Giving to a Charity, 

• Consumer Financial Protection Bureau's Frauds and scams, and 

• CISA’s Phishing Guidance, Stopping the Attack Cycle at Phase One to help organizations reduce likelihood and impact of successful phishing attacks.

Today, CISA and FBI released a Secure by Design Alert, Eliminating Cross-Site Scripting Vulnerabilities, as a part of our ongoing effort to reduce the prevalence of vulnerability classes at scale. Vulnerabilities like cross-site scripting (XSS) continue to appear in software, enabling threat actors to exploit them. However, cross-site scripting vulnerabilities are preventable and should not be present in software products.

CISA and FBI urge CEOs and other business leaders at technology manufacturers to direct their technical leaders/teams to review past instances of these defects and create a strategic plan to prevent them in the future.

Today, the Cybersecurity and Infrastructure Security Agency (CISA) released the Federal Civilian Executive Branch (FCEB) Operational Cybersecurity Alignment (FOCAL) Plan. Developed in collaboration with FCEB agencies, this plan provides standard, essential components of enterprise operational cybersecurity and aligns the collective operational defense capabilities across the federal enterprise.

Currently, federal agencies maintain their own networks and system architectures—and they independently manage their cyber risk. CISA’s FOCAL plan aligns the federal enterprise, empowering agencies to better address the dynamic cyber threat environment collectively. The plan recommends actions that substantively advance operational cybersecurity improvements and alignment goals.
