This article explains the principles and common scenarios of prompt injection attacks on LLMs and provides practical defense strategies—including rule reinforcement, input filtering, output verification, and advanced techniques—to protect AI systems from malicious manipulation.
As U.S. and Israeli forces target Iranian nuclear sites, analysts warn that Iran and its proxy hackers are poised to launch large‑scale cyber retaliation against critical U.S. and Israeli infrastructure, with sophisticated APT groups, upgraded attack methods, and high‑risk targets spanning energy, finance, and public utilities.
This article explains what denial‑of‑service (DoS) attacks are, describes their underlying principles and common variants such as SYN, UDP, ICMP, and HTTP floods, and outlines comprehensive defense strategies including firewalls, IDS, CDN, multi‑active architectures, SYN cookies, rate limiting, and cloud‑based protection services.
The WiS Platform provides a game‑based environment for benchmarking large language models in multi‑agent settings, measuring reasoning, deception and collaboration through dynamic scenarios, offering fair experimental design, real‑time competition, visualizations, detailed metrics, and open‑source tools, with GPT‑4o outperforming other models such as Qwen2.5‑72B‑Instruct.
The article explains how misconfigured caches and inconsistent front‑end/back‑end parsing enable web cache poisoning and HTTP request smuggling attacks, illustrates practical exploitation scenarios, and recommends disabling caching, unifying request‑boundary logic, and adopting HTTP/2 or strict configurations to defend against these high‑impact threats.
This article explains how Active Directory domains work, outlines over 220 attack techniques such as SPN scanning, password spraying, Kerberoasting, DCSync, and privilege‑escalation exploits, and then presents comprehensive defense measures including attack‑surface reduction, strict admin hygiene, network isolation, honeypots, and continuous monitoring.
The article provides a comprehensive overview of phishing as a social‑engineering attack, detailing its various techniques—including email deception, spear‑phishing, whaling, malware‑based lures, domain spoofing, vishing, SMS and QR‑code scams—and offers practical defense measures such as anti‑phishing tools, multi‑factor authentication, content filtering, and security standards.
On April 8, a record‑breaking 1.23 Tbps DDoS attack—dominated by SSDP reflection and launched by roughly 166 000 mostly Chinese sources, including PCs, IDC servers and IoT devices—targeted a Tencent Cloud‑hosted game, prompting the article to urge operators to assess risk, adopt high‑protection services, conceal origin IPs, and tailor defense policies with expert assistance.
From a front‑end engineer’s viewpoint, this article dissects web security as a holistic system, examines attack motives, targets, and vectors across browsers, transmission channels, and servers, and proposes coordinated front‑end and back‑end defenses such as encryption, signing, XSS filtering, URL whitelisting, and CSRF mitigation.
This comprehensive guide explains why database injection remains a critical security threat, illustrates real‑world attack techniques and toolchains, and provides layered defensive measures—from secure coding and DB‑proxy solutions to web‑server filtering, WAF deployment, and log‑analysis pipelines.
This article examines the XOR.DDoS Linux trojan (sample 101), detailing how it hijacks crontab to launch malicious scripts, the forensic clues left in system logs, and a step‑by‑step emergency removal procedure, while also discussing its polymorphic nature and the broader challenges of defending against such malware.
This article provides a detailed classification of DDoS attacks—including network‑layer, application‑layer, hybrid, reflection, pulse, and link‑flooding methods—and outlines a four‑layer defense architecture (ISP/WAN, CDN/Internet, Data‑Center, OS/APP) along with practical mitigation techniques and considerations for different enterprise sizes.
