Summary Points The Cybersecurity and Infrastructure Security Agency (CISA) urges critical infrastructure owners to develop plans for operating securely in emergency conditions for extended periods, potentially months, including isolating from IT and third-party systems. CISA is collaborating with the private sector through the CI Fortify initiative to assess vulnerabilities, test recovery plans, and ensure continuity of services, especially in sectors like energy, water, and defense. Core strategies include isolating operational technology (OT) from external networks during crises and establishing internal protocols to maintain essential services when disconnected from IT or third-party vendors. Despite efforts to combat Chinese hacking groups like…

Top Highlights A supply chain attack has compromised DAEMON Tools installers, delivering malicious payloads from April 8, 2026, impacting thousands across over 100 countries. The malware activates during system startup, downloading and executing a series of payloads, including system info collectors and a backdoor for remote commands. The attack appears targeted, affecting specific organizations in Russia, Belarus, and Thailand, with evidence suggesting a Chinese-speaking threat actor. This incident highlights the rising sophistication of software supply chain breaches, emphasizing the need for organizations to monitor and isolate affected systems. Supply Chain Attack Targets Trusted Software with Malicious Files Recently, cybersecurity researchers…

Quick Takeaways North Korean hackers are increasingly targeting individuals within crypto firms through social engineering and insider recruitment, shifting from system-based attacks. Attackers employ fake websites, suspicious wallet addresses, and detailed profiles to facilitate active hacking campaigns, making threat detection more complex. Rapid, shared intelligence—like Ripple’s collaboration with Crypto ISAC—enables early detection and swift response to social engineering and insider threats, reducing potential losses. Threats, Attack Techniques, and Targets Ripple recently shared intelligence about North Korean hacking groups with Crypto ISAC. These hackers are now focusing more on social engineering and insider threats. They often target employees seeking jobs at…

Fast Facts Trellix disclosed a breach where a threat actor accessed part of their source code repository, but no evidence suggests exploitation or impact on source code distribution. The company is investigating with forensic experts and law enforcement, but key details like repository location and attacker identity remain unclear. Past attacks on cybersecurity firms’ source code, such as F5 Networks, Okta, and Lastpass, highlight ongoing risks to supply chain security and downstream customers. Experts warn that while current access may be limited, source code breaches can reveal vulnerabilities and complicate mitigation efforts, posing future security risks. Unauthorized Access to Trellix…

Quick Takeaways CISA’s CI Fortify initiative aims to enhance critical infrastructure resilience by preparing organizations to operate independently of external connectivity during cyberattacks. The plan emphasizes operational readiness through planning, testing, and the ability to quickly restore systems in isolation, moving beyond traditional disaster recovery approaches. Key challenges include a lack of visibility into dependencies within complex networks and the high costs associated with building resilient infrastructure. Effective remote access controls must be rethought, with a focus on secure, auditable, crisis-capable systems to prevent expanding attack surfaces during disruptions. The Core Issue The US Cybersecurity and Infrastructure Security Agency (CISA)…

Quick Takeaways A Latvian national, Deniss Zolotarjovs, was sentenced to 102 months in prison for involvement in ransomware attacks that extorted over $16 million from more than 54 companies, including a U.S. government entity. Zolotarjovs helped lead a ransomware organization, associated with former Conti group members, that targeted victims primarily in the U.S. and used multiple aliases like Conti, Royal, and others. The group’s crimes caused hundreds of millions of dollars in losses and included leaking sensitive data, such as children’s health records, impacting tens of thousands of individuals. Zolotarjovs was arrested in Georgia, extradited to the U.S., pleaded guilty…

Essential Insights Zero Trust is a mindset, not a product; organizations must adopt a cultural shift that emphasizes a security-first attitude, carefully managing exceptions to ensure smooth workflows. Assuming software is compromised highlights the importance of restrictive controls — instead of just access, focus on blocking malicious actions even after vulnerabilities are found. Default-deny focuses on stopping breaches early by preventing malicious code from executing, addressing the attack at its source rather than relying solely on detection. Controls are about managing human error, not distrust; implementing "deny by default" protects against inevitable mistakes, ensuring security without hindering productivity. Problem Explained…

Summary Points A critical vulnerability (CVE-2026-23918) in Apache HTTP Server 2.4.66 allows remote code execution and DoS via a double free in HTTP/2 protocol handling, especially exploitable on default Debian and Docker setups. Attackers can trigger the flaw through malicious HTTP/2 HEADERS and RST_STREAM frames, causing server crashes or executing arbitrary code by manipulating memory via mmap reuse and fake structures. The severity is heightened by widespread HTTP/2 deployment; the flaw primarily affects multi-threaded servers with mod_http2 enabled, posing significant risk of persistent DoS and remote Code execution attacks. Threat, Attack Techniques, and Targets The Apache HTTP/2 vulnerability (CVE-2026-23918) is…

These threats include phishing, brand abuse, impersonation of executives, and exposure of login details. The threat…

Fast Facts Microsoft Edge stores all user passwords in clear text within process memory, accessible through simple memory dump techniques, exposing sensitive credentials without requiring elevated privileges. Attackers can easily extract these plaintext passwords by analyzing Edge’s memory dumps with standard tools like "strings," leading to credential theft and potential account compromise. Despite browser security prompts, Edge’s inherent data handling practices make user credentials vulnerable to misuse, highlighting a critical security flaw in credential storage. Threat, Attack Techniques, and Targets Recent research reveals a serious security concern with Microsoft Edge. The browser stores all user passwords in plain text, even…
