Security researchers dissecting the open‑source Shai‑Hulud supply‑chain attack worm uncovered a bizarre Python‑version Easter egg that checks a host’s geolocation, and with a 1‑in‑6 chance plays a blaring alarm and deletes all files on machines located in Israel or Iran.
Zapper, a Linux process‑hiding tool created by Hacker’s Choice, runs without root, manipulates the ELF auxiliary vector via ptrace, hides command‑line arguments, environment variables and child processes with negligible overhead, and has been observed in real Ukrainian cyber‑war operations, prompting specific defensive recommendations.
In just three months the US Pentagon shifted from publicly rejecting AI weaponization to signing contracts with eight leading tech firms, creating a four‑layer AI‑driven closed loop that makes AI the central brain of modern warfare and grants it access to top‑secret IL‑6 and IL‑7 networks.

FortiGuard Labs reveals a sophisticated SEO poisoning campaign that lures Chinese Windows users to fake software sites, delivers hidden Hiddengh0st and Winos malware, employs anti‑analysis tricks, establishes persistence, and exfiltrates data, while the article breaks down the full attack chain and offers practical defense steps.
This article explains the principle and step‑by‑step flow of Cross‑Site Request Forgery attacks, illustrates common exploitation techniques such as forged GET/POST requests and click‑bait links, and outlines practical defenses including POST usage, HttpOnly cookies, CSRF tokens, and double‑submit cookie validation.
This article explains what network ports are, classifies well‑known, registered and dynamic ports, demonstrates scanning tools and commands, details common attack techniques such as buffer overflow, DoS and MITM, and provides practical hardening recommendations for the most frequently targeted ports.
The article explains how to protect Spring Boot applications from XSS attacks by using custom annotations such as @XSS with an XssValidator and by implementing a request‑filter chain—including XssFilter and XssWrapper—to sanitize input, demonstrating through tests that both approaches reliably secure user data.
This article explains what ransomware is, outlines its main variants such as encryption‑based, lock‑screen and doxware ransomware, describes common infection vectors like brute‑force, phishing and exploit kits, and provides practical network‑ and host‑side defenses as well as response steps if an attack occurs.
India’s Ministry of Defence is rolling out Maya OS, a domestically‑developed, Ubuntu‑based operating system with built‑in full‑disk encryption, intrusion detection, sandboxing, and the Chakravyuh endpoint protection suite, aiming to replace Windows on all connected military computers by year‑end.
This article explains what HTTP request smuggling is, how the vulnerability arises from conflicting Content‑Length and Transfer‑Encoding headers, describes common CL.TE, TE.CL and TE.TE attack patterns, and outlines detection techniques and defensive measures for modern web infrastructures.
This article explains what directory (path) traversal is, demonstrates how attackers can read or write arbitrary files on a server by manipulating file‑path parameters, outlines common bypass techniques, and provides concrete defensive coding practices to mitigate the vulnerability.
This article provides a comprehensive overview of Cross‑Site Scripting (XSS), explaining its definition, dangers, underlying mechanisms, classification into stored, reflected, and DOM‑based types, common injection vectors, and practical defense strategies, while also addressing common questions and resources for further learning.
