State-Sponsored Hackers Exploit Palo Alto Networks Zero-Day to Breach Networks
A critical zero-day vulnerability (CVE-2024-3400) in Palo Alto Networks firewalls has been exploited by suspected state-sponsored hackers since March 26 to breach internal networks, steal data, and credentials. The attackers installed a custom Python backdoor named 'Upstyle' to execute commands on compromised devices and pivot to internal networks. Volexity, who discovered the zero-day, believes the attackers are highly likely to be state-sponsored based on the resources required and the capabilities displayed.
LG Smart TV Vulnerabilities Allow Root Access and Command Injection
Researchers discovered vulnerabilities in LG webOS on smart TVs that enable authorization bypass and root access. The flaws, CVE-2023-6317 through CVE-2023-6320, impact webOS versions 4.9.7 to 7.3.1 and were patched in March 2024. Exploitation allows gaining elevated privileges and running arbitrary commands, potentially impacting over 91,000 internet-exposed devices primarily in South Korea, Hong Kong, and the U.S.
Raspberry Robin Malware Evolves to Use Highly Obfuscated Windows Script Files for Initial Infection
The Raspberry Robin Windows worm has updated its infection chain to deliver payloads via heavily obfuscated Windows Script Files (WSF). These scripts implement robust anti-analysis and virtual machine detection capabilities to evade security controls. The malware establishes device integrity checks before downloading its DLL payload, adds Microsoft Defender exclusions, and restarts execution to break debugger sessions.
GitHub Repositories Abused to Spread Keyzetsu Malware
Threat actors are using GitHub automation features and malicious Visual Studio projects to distribute a new variant of the Keyzetsu clipboard-hijacking malware, targeting cryptocurrency payments. The attackers create GitHub repositories with names optimized for search rankings and artificially boost their popularity using automated commits and fake accounts. Users downloading files from these repositories are infected with malware hidden within Visual Studio project files, which is stealthily executed during the build process.
Metasploit Meterpreter Installed via Vulnerable Redis Servers
Attackers are targeting misconfigured and outdated Redis 3.x servers to install Metasploit Stager malware and the PrintSpoofer privilege escalation tool. The Stager downloads the memory-resident Meterpreter backdoor from a C&C server, providing ongoing access. Organizations running Redis should update to the latest version, restrict external access to servers, and use endpoint protection to detect and block the malware.
AI & Security
Cybercrime Group Uses Likely AI Script to Load Info Stealer
Proofpoint researchers identified TA547 targeting German organizations with an email campaign delivering Rhadamanthys malware, an information stealer. The actor appeared to use a PowerShell script suspected to be generated by a large language model (LLM) to load the malware into memory without writing it to disk. While LLMs can assist threat actors, the potentially LLM-generated code did not change the malware's functionality or impact defenses against it.
AI-Powered Security Platforms Race Heats Up with Microsoft, Google, and Simbian
Microsoft, Google, and startup Simbian are investing heavily in generative AI (GenAI) systems to automate cybersecurity tasks using natural language.

Sama's team conducts tests using real-world scenarios to identify potential risks and determine whether prompts should be refined or recreated to enhance AI safeguards.
Leadership Insights
CISOs Struggle to Sell Cybersecurity Value and Face Burnout
Allan Alford, CEO at Alford and Adams Consulting, shares that two CISOs he spoke with recently wanted to quit not just their roles but the cybersecurity field altogether due to feeling a lack of leadership support. Alford emphasizes the need for CISOs to effectively sell the value of their work, continuously re-evaluating their approach and seeking feedback from peers while also prioritizing self-care to avoid burnout in this challenging role.
Using "No" Strategically Can Help CISOs Drive Business Value
Clarke Rodgers from AWS says that CISOs should track how often they must say "No" to business requests. If a CISO has to frequently say "No", it indicates the organization lacks a strong security culture, adequate funding, and executive understanding of cyber risk. CISOs can use data on the cost of saying "No" to justify initiatives like building security into CI/CD pipelines, embedding Security Ambassadors in product teams, and supporting AI adoption while mitigating risks.
How Google Cloud’s Office Of The CISO Is Shaping The Future
Forbes sits down with the members the Office of CISO of Google Cloud. The OCISO aims to address the unique cybersecurity challenges and regulatory landscapes of each sector by providing tailored, empathetic guidance rooted in the team's experience as former CISOs. Members share details about their approach, frameworks and ways of working.
Playbooks Provide Context and Automation for SecOps
Aimei Wei, founder and CTO of Stellar Cyber, discusses how playbooks can enhance SecOps by providing context and automation. Traditional SecOps techniques struggle to combine insights from various tools, but playbooks in XDR solutions offer visibility into the entire attackSurface while correlating alerts using AI and ML. Playbooks can automate response actions and improve analyst productivity through better root cause analysis.
Career Development
Mentorship Crucial for Building Successful Security Careers
Michael Dorn, Executive Director of Safe Havens International, emphasizes the mutual benefits of mentorship, learning from both superiors and employees. Jennifer Franks, Director of Information Technology and Cybersecurity at GAO, highlights the need for tailored mentorship approaches to navigate the vast and fast-moving cybersecurity field. Shannon Brewster, Director and General Manager at AT&T Cybersecurity, thinks having a mentor is probably one of the most instrumental things that you can have in terms of really realizing success. Colin Daugherty mentions the leadership is about promoting others before yourself.
NIST Releases Free Online Courses on SP 800-53 Security and Privacy Controls
NIST has released three free online introductory courses covering the SP 800-53 security and privacy control catalog, SP 800-53A control assessment procedures, and SP 800-53B control baselines. The courses provide high-level overviews of foundational security and privacy risk management concepts based on their respective NIST Special Publications. The courses range from 45-60 minutes and do not require registration, making them easily accessible for those looking to gain a basic understanding of these important cybersecurity standards.

How I discovered a 9.8 critical security vulnerability in ZeroMQ with mostly pure luck and my two cents about xz backdoor
Fang-Pen Lin shares how she discovered CVE-2019-13132 in ZeroMQ while implementing authentication using CurveZMQ. Vulnerability allowed stack overflow via large metadata in authentication payload, achieving CVSS 9.8 severity. Quickly patched and disclosed to ZeroMQ maintainers, who rolled out fix to major Linux distributions.
Combining SaaS Attack Techniques for Effective Attack Chains
Poisoned tenants involve an adversary registering a SaaS app tenant they control and tricking target users to join it. SAMLjacking is where an attacker uses SAML SSO configuration settings for a SaaS tenant they control to redirect users to a malicious link during authentication. Combining these techniques allows an attacker to compromise user credentials without direct phishing, potentially leading to businessImpact across multiple SaaS applications.
How I got RCE in one of Bugcrowd's Public Programs
Bug bounty hunter, discovered an Apache Struts 2 instance running on a non-standard port during reconnaissance of a Bugcrowd public program's assets using Shodan. After fuzzing directories and attempting to exploit known CVEs for the specific Tomcat versions, an OGNL injection payload was successfully used to achieve remote code execution via the showLogin.action endpoint. The vulnerability was reported to Bugcrowd and the program resolved it by decommissioning the affected asset.
