In this episode, we break down the massive supply chain attack that rocked the React Native ecosystem beginning on June 6, 2025. Over 16 NPM packages, collectively downloaded over one million times per week, were silently weaponized with a Remote Access Trojan (RAT) embedded in obfuscated code. The attack, linked to the same threat actor behind the May 2025 rand-user-agent breach, exploited a compromised contributor token to inject malicious payloads into widely used libraries under the @react-native-aria and @gluestack-ui namespaces.

We examine how the malware embedded itself stealthily—using whitespace padding, hidden payloads, and path hijacking to achieve long-term persistence, especially on Windows systems. The trojan's capabilities include arbitrary command execution, system data exfiltration, and stealthy control via hardcoded C2 servers on non-standard ports. Despite the maintainers’ response—deprecating affected versions and implementing 2FA—experts warn that system-level compromises may already be widespread.

This incident is not isolated. We also highlight related supply chain attacks across NPM, PyPI, and even browser extensions and macOS malware. From credential theft to sabotage and full host takeovers, these threats underscore a growing trend: open-source ecosystems are high-value targets, and current trust models are not enough.

Join us for a deep technical dive into what happened, how it was detected, what makes this attack different—and what you must do now if you rely on these packages.

In this episode, we examine Taiwan’s growing alarm over Chinese mobile applications , especially TikTok and WeChat, in light of rising global concern over data privacy and foreign surveillance. A recent inspection by Taiwan’s National Security Bureau (NSB) revealed that these apps aggressively collect personal data and transmit it to servers located in mainland China—where national laws require that user data be made available to Chinese government authorities upon request. Taiwan’s warning isn’t isolated—it echoes fears expressed by governments across the world, from the United States to India to European regulators, who see apps like TikTok, WeChat, and others as national security risks . At the center of this debate lies the Data Security Law (DSL) of the People’s Republic of China , a sweeping mandate that compels companies to store data within China and hand it over for national intelligence purposes. Taiwan’s NSB highlighted violations such as the unauthorized collection of facial recognition data, contacts, geolocation, and more—actions that could be leveraged for foreign surveillance, espionage, or influence operations. We explore: The mechanics of data collection by TikTok, WeChat, and similar Chinese-developed apps—including how these apps access sensitive personal information far beyond what's needed for their core functionality. How Chinese national laws—especially the DSL, Cybersecurity Law, and National Intelligence Law—enable state access to user data stored by any company operating in or connected to China. Taiwan’s broader national security context , including cyberattacks and espionage targeting its infrastructure, which raise the stakes for data security. Parallel concerns from other nations , including EU investigations into unlawful data transfers, India’s outright bans on hundreds of Chinese apps, and ongoing U.S. debates about TikTok's fate. The potential for foreign influence through content curation , especially via algorithmic targeting of political messages and behavioral profiling enabled by biometric data collection. Regulatory dilemmas facing democracies: how to balance free markets and open technology with the imperative to protect citizens’ data and national infrastructure. Taiwan’s alignment with global trends in confronting China-developed software—not just through advisories but also through technological countermeasures and increased cyber resilience efforts . The episode also covers what average users can do: re-evaluating app permissions, avoiding features with poor transparency, and understanding the geopolitical stakes behind seemingly innocuous mobile platforms.…
 
This episode exposes the growing menace of Atomic macOS Stealer (AMOS) — a rapidly evolving malware-as-a-service (MaaS) platform targeting macOS users worldwide. Once seen as a simple data stealer, AMOS has matured into a potent, long-term threat featuring keyloggers , a persistent backdoor , and system-level access , all designed to exfiltrate data and maintain control over compromised systems. AMOS now enables threat actors to remotely execute commands, spy on users, and re-infect devices even after reboot , thanks to advanced macOS persistence techniques like LaunchDaemons and hidden binary scripts. Its infection chain relies on social engineering, counterfeit applications, and tampered DMG installers — making even savvy Mac users vulnerable. This episode explores: AMOS's evolution from stealer to full-platform malware with persistent remote access Key features of the latest version, including a keylogger and embedded backdoor capable of running arbitrary commands Real-world attack vectors , such as phishing campaigns, cracked software, poisoned torrents, and fake job ads targeting cryptocurrency holders and freelancers The use of macOS persistence mechanisms (LaunchDaemons, osascript, ScriptMonitor) and Gatekeeper evasion Cross-platform development in GoLang, allowing the malware to operate seamlessly across Mac architectures The global impact , with campaigns spanning over 120 countries and rising infection rates in the U.S., U.K., France, and Canada How AMOS compares to Cthulhu Stealer and North Korea-aligned tools like RustBucket and macOS BeaverTail Practical security steps to detect and mitigate AMOS, including IOC monitoring, digital signature verification, and behavioral endpoint defenses AMOS has rapidly become one of the top three most detected macOS threats , signaling a paradigm shift in Mac-targeted malware. With crypto wallets, browser data, and personal credentials at risk, this episode is essential listening for anyone in cybersecurity, IT, or using Macs in high-risk industries.…
 
In this episode, we dissect CitrixBleed 2 —a newly disclosed and actively exploited vulnerability affecting Citrix NetScaler ADC and Gateway appliances. Tracked as CVE-2025-5777 (and possibly also CVE-2025-6543), this critical flaw mirrors the notorious original CitrixBleed by allowing attackers to extract sensitive memory content , including user session tokens , through crafted POST login requests. Despite Citrix’s claims that there’s no active exploitation, threat intelligence reports from security researchers and government agencies like CISA tell a different story: public proof-of-concept exploits are circulating , and attacks have been observed as early as mid-June. The vulnerability stems from a format string misuse involving the snprintf function, allowing memory leakage in small byte increments—enough for determined attackers to reconstruct sensitive data, hijack authenticated sessions, and potentially access administrative utilities. We cover everything from the technical mechanics of the vulnerability to the strategic mitigation steps enterprises must take. Affected systems include NetScaler MPX, VPX, SDX , and NetScaler Gateway , making the scope of risk widespread, especially in large-scale remote access and cloud deployments. In this episode, we unpack: How CVE-2025-5777 works, including the format string flaw and session token exposure Indicators of active exploitation and CISA’s inclusion of related CVEs in its KEV catalog The timeline and evidence suggesting exploitation began weeks before disclosure Why slow patch adoption is increasing risk across industries A guided breakdown of the NetScaler Secure Deployment Guide , covering: Strong authentication, MFA, and password security Role-based access control (RBAC) and session management Secure traffic segmentation, ACL configuration, and TLS hardening App-layer protections like WAF and rewrite policies for cookie security Logging, SNMP configuration, and remote syslog best practices DNSSEC and cryptographic key management How to verify patch status via the NetScaler Console and initiate remediation scans This episode delivers a clear message: Patch now, monitor aggressively, and revisit your NetScaler hardening strategy . With public exploits in circulation and attackers harvesting session tokens, this vulnerability represents a pressing concern for enterprises relying on Citrix infrastructure.…

At the center of this month’s update is CVE-2025-30012 , a critical unauthenticated command execution flaw in SAP Supplier Relationship Management (SRM). Initially classified as high priority, this vulnerability has now been escalated to critical status due to its severe impact. Also in the spotlight: a remote code execution bug in SAP S/4HANA and SCM (CVE-2025-42967) , and four insecure deserialization vulnerabilities affecting SAP NetWeaver Java systems—longtime targets for threat actors and ransomware groups alike. While there are no confirmed in-the-wild exploits for these new issues, history tells us that such gaps don’t remain unexploited for long. Just earlier this year, vulnerabilities in SAP’s Visual Composer framework were actively exploited by ransomware operators like BianLian and RansomEXX . As threat actors grow more sophisticated and supply chain targets grow more lucrative, patch speed has never been more important. This episode covers: The vulnerabilities patched in SAP’s July advisory and their real-world risk Why CVSS scoring matters —and how SAP determines what counts as "critical" The SAP vulnerability lifecycle , and how organizations can use structured frameworks for patch and incident management Key lessons from past exploits , including zero-day activity targeting SAP systems The shared security model in cloud deployments like RISE with SAP—and what you’re responsible for vs. what SAP handles Why alert fatigue and delayed patching are existential threats in SAP environments How to verify your patch level, interpret SAP Notes, and ensure you’re protected We also discuss how critical tools like SecurityBridge , NIST-aligned vulnerability workflows, and proactive community engagement can help mitigate threats and support SAP admins, DevSecOps teams, and CISOs navigating the growing complexity of ERP security.…
 
In this episode, we explore a shadowy and unconfirmed—but highly consequential—data breach at Spanish telecommunications giant Telefónica. Allegedly orchestrated by the HellCat ransomware group, the breach involves a staggering 106GB of exfiltrated data, including internal communications, customer records, and employee information. Telefónica has yet to acknowledge the breach publicly, while the threat actor “Rey” released a 5GB sample to support their claim, pointing to a Jira server misconfiguration as the entry point. We unpack the evolving tactics of HellCat—a ransomware gang known for targeting Atlassian’s Jira platform—and examine how such misconfigurations continue to expose sensitive data across major organizations like NASA, Google, and Yahoo. Telefónica is no stranger to HellCat; a similar attack occurred in January, making this latest breach appear not only credible but also indicative of ongoing remediation failures. But this isn’t just a story about technical lapses—it’s also a warning shot for every organization subject to the GDPR and Spain’s national data protection laws. We dig into the regulatory implications, potential fines, and legal obligations that Telefónica could face if the breach is confirmed. You'll also hear why Atlassian’s Jira platform has become a soft target for threat actors, and what companies need to do to harden their SaaS deployments against similar threats. Finally, we explore frameworks for responsible breach response—from immediate containment to post-incident review—and what every enterprise should learn from this growing wave of misconfiguration-fueled cyberattacks. Key discussion points include: The anatomy of the Telefónica breach and the leaked data How HellCat exploits Jira misconfigurations and infostealer-compromised credentials The broader trend of Atlassian-based intrusions across multiple industries GDPR and NLOPD obligations: What counts as a notifiable breach? Regulatory fines, reputational risks, and the right to compensation Best practices for SaaS security and breach response in 2025 This episode is a must-listen for CISOs, privacy officers, IT security professionals, and legal teams navigating the intersection of cybersecurity failures and regulatory exposure.…
 
The recent ransomware attack on Ingram Micro , a global technology distribution giant, reveals not only a sophisticated human-operated cyber assault—but also the fragile state of modern supply chain cybersecurity. In this episode, we break down how attackers, believed to be affiliated with the SafePay ransomware group , penetrated Ingram Micro’s infrastructure, reportedly by exploiting a Palo Alto GlobalProtect VPN vulnerability and leveraging stolen credentials. The breach disrupted the company’s website and order systems, impacting partners and resellers worldwide. This case is a microcosm of a much larger threat: ransomware groups are evolving, using targeted, manual operations rather than automated malware blasts. And when a company like Ingram Micro gets hit, the downstream effects ripple through entire IT ecosystems. This episode explores the deeper story behind the headlines, including: Human-operated ransomware tactics , including credential theft, privilege escalation, lateral movement, and double extortion. The critical vulnerability CVE-2024-3400 in GlobalProtect , which is being actively exploited in real-world ransomware campaigns. SafePay’s emergence in 2025 as a serious actor, using stolen VPN credentials and backdoor persistence methods to deploy ransomware discreetly. How human-operated ransomware attacks differ from commodity malware—and why they're more dangerous.

In a sudden and cryptic announcement, the notorious ransomware group Hunters International has declared its shutdown, citing “recent developments” and pledging to release decryption keys to victims. Active since late 2022 and suspected to be a rebrand of the earlier Hive ransomware gang , Hunters International has been responsible for attacks on nearly 300 organizations across various industries. Yet, cybersecurity experts believe this announcement is less about remorse—and more about reinvention. In this episode, we dissect what this “shutdown” really means. Far from disappearing, the group may already be operating under a new name: World Leaks . This episode explores the lifecycle of ransomware gangs and how rebranding, splintering, and strategic pauses are common tactics used to throw off law enforcement and improve operational resilience. Key discussion points include: The lifecycle of ransomware groups, from emergent to established , using the GRIT taxonomy. How rebranding is used to evade law enforcement pressure and manage public perception, especially after high-profile disruptions. The Hive–Hunters–World Leaks lineage , and what indicators point to continuity rather than closure. Why law enforcement actions rarely shut down ransomware permanently, often leading to splinter or successor groups . The business model of ransomware , including double extortion, data leak sites, and Ransomware-as-a-Service (RaaS). Which sectors remain most vulnerable—including manufacturing, professional services, finance, and education —and how victim selection is increasingly based on financial footprint and data value . The significance of public communications and tactics like apologies, targeting rules, and ethics messaging used to shape ransomware groups' public image. The importance of ransomware payment tracking via blockchain , with insights into Bitcoin-based laundering operations and the transparency paradox of public ledgers. The value of Ransomware Susceptibility Index™ (RSI) metrics to help organizations prioritize defenses and understand their exposure. This case study of Hunters International exemplifies the strategic fluidity of modern ransomware operations —where shutting down may simply mean rebooting under a different brand. For defenders, staying ahead means recognizing these patterns, maintaining continuity in threat intelligence, and preparing for the next iteration before it strikes.…

In this episode, we uncover a high-stakes cyber campaign targeting the heart of French digital infrastructure. ANSSI , France’s national cybersecurity agency, has exposed a Chinese-linked hacking group known as Houken (UNC5174 or Uteus) responsible for a widespread espionage operation since late 2024. This state-adjacent threat actor infiltrated critical sectors including government, media, transport, telecom, and finance using an arsenal of sophisticated tactics—blending zero-day exploits, rootkits, and stealthy post-exploitation tools. The Houken group leveraged multiple zero-day vulnerabilities in Ivanti Cloud Service Appliances (CSA) —CVE-2024-8190, CVE-2024-8963, and CVE-2024-9380—to gain initial access. But this wasn’t just about intrusion; Houken’s operators dug in deep: stealing credentials, moving laterally , and deploying a rare Linux kernel-mode rootkit capable of hijacking any inbound TCP traffic while remaining virtually invisible to traditional defenses. What sets this campaign apart isn’t just its technical sophistication—it’s the hybrid nature of the threat. ANSSI suggests Houken may be a cyber mercenary group , simultaneously working in the service of China’s Ministry of State Security (MSS) and pursuing financial gains , such as cryptocurrency mining and reselling system access. This “multiparty approach” signifies a dangerous evolution in cybercrime—where espionage and monetization coexist within a single operational framework. We delve into: The attack chain : from zero-day exploitation to credential harvesting and stealth persistence. The rootkit sysinitd.ko : a kernel module granting root-level command execution while avoiding detection. Defense evasion tactics : including timestomping , log deletion , and self-patching vulnerabilities to lock out rival threat actors. Houken’s toolkit : a mix of commodity utilities (Nmap, Netcat, Fscan) and custom implants (PHP webshells, SparkRAT, Neo-reGeorg). Operational clues that tie activity to China Standard Time (UTC+8) and highlight probable MSS alignment. This is more than a breach. It’s a signal that cyber mercenary operations are maturing , and European states are squarely in the crosshairs. The Houken campaign forces a reconsideration of perimeter defenses, zero-day management, and detection strategies for advanced persistent threats. Whether you’re a security architect, CISO, or public sector technologist, this episode provides a deep and essential briefing on one of the most sophisticated cyber espionage efforts uncovered in 2025.…
 
In this episode, we examine a growing threat reshaping financial crime in Europe: sophisticated, technology-driven investment fraud. Spanish law enforcement has recently dismantled a fraud operation that spanned multiple years, deceived over 300 victims, and resulted in more than $11.8 million in losses. What made this case particularly notable was the use of high-pressure call centers inside Spain , supported by strategic psychological manipulation , to drive fraudulent investments advertised across social media platforms. The scheme, launched in 2022, mimicked the playbook of larger international fraud networks—slick branding, convincing digital ads, and seemingly personalized pitches to lure in unsuspecting investors. Behind the scenes, victims were connected to well-trained fraud agents posing as investment advisors who used scripted tactics to manipulate emotional trust and urgency. This case, however, is just one node in a much broader web of financial crime being actively investigated across Spain: Authorities arrested 21 individuals and seized luxury vehicles, stacks of cash, and other high-value assets linked to the scheme. In a separate crackdown, Spanish police disrupted a ring that laundered over €500 million , highlighting the scale and integration of illicit finance operations within legitimate economic channels. Another scam exploited AI-generated advertisements and deepfakes to lure cryptocurrency investors into fake opportunities, netting €19 million. We unpack the evolving tactics used by fraudsters , including: Social engineering techniques that exploit emotional triggers and authority bias. The use of AI and deepfakes to create authentic-looking investment platforms and personalities. Affinity fraud , where scammers target members of specific communities or shared identity groups to exploit trust. The integration of cryptocurrency and decentralized finance (DeFi) to obscure money trails and enable rapid laundering. This episode also dives into the regulatory landscape , including how the EU’s Anti-Money Laundering Directive (AMLD) and organizations like FATF and Moneyval are attempting to curb these activities through stricter oversight, risk-based frameworks, and obligations for financial and non-financial intermediaries to report suspicious transactions. As these fraud rings adopt increasingly advanced tools—ranging from Telegram social engineering to metaverse impersonations—Spain’s efforts signal a broader shift: financial crime is becoming cybercrime , and law enforcement must keep pace. Whether you’re a financial compliance professional, cybersecurity lead, or simply someone navigating digital investments, this episode is your briefing on where the threat landscape is heading—and what can be done to stay one step ahead.…

A critical new WordPress vulnerability— CVE-2025-6463 —has been discovered in the widely used Forminator plugin , affecting over 600,000 active installations and putting hundreds of thousands of websites at risk of full compromise. In this episode, we dive deep into the mechanics, risks, and remediation of this arbitrary file deletion flaw and explain what every WordPress administrator, developer, and security professional needs to know. At the heart of this issue is improper validation in how the Forminator plugin handles file paths when deleting form entries. This allows unauthenticated attackers to inject file paths into form submissions—even in fields not meant to accept files—and trick the system into deleting critical WordPress files like wp-config.php. The result? A full site reset , granting attackers an opportunity to seize control of the site . Here’s what we unpack in this episode: The CVE-2025-6463 Vulnerability : How the exploit works, which function is flawed (entry_delete_upload_files), and why unsanitized file arrays in form fields make this so dangerous. Real-World Impact : Deleting wp-config.php can reset a WordPress site, giving an attacker a window to install a fresh site under their control . Scope of Exposure : Over 400,000 sites remain unpatched , and many administrators may not even be aware they’re running outdated versions of the Forminator plugin. The Fix in Version 1.44.3 : We discuss how the patch restricts deletions to specific field types, limits file deletions to safe directories, and enforces path normalization and filename sanitization.

In one of the latest large-scale data breaches to hit the U.S. private sector, Kelly Benefits , a provider of payroll and benefits administration services, disclosed a significant cybersecurity incident impacting over 553,000 individuals . The breach, which occurred in December 2024 but was only revealed in April 2025 , exposed sensitive personal information—including names, Social Security numbers, financial data, and even medical records —of employees linked to over 40 partner organizations , such as Aetna Life Insurance and United Healthcare .

The Invisible Cost of Vendor Vulnerabilities : How breaches at service providers can cascade downstream, exposing thousands of individuals tied to organizations with no direct involvement in the original breach. The Growing Identity Theft Epidemic : With over 500,000 individuals exposed in this incident alone, we look at how breaches like this contribute to financial fraud, medical identity theft , and long-term privacy violations.
