If you have ever logged into a corporate computer, searched for a colleague in your company’s email directory, or used a single set of credentials to access dozens of different internal applications, you have likely interacted with LDAP . Standing for Lightweight Directory Access Protocol , LDAP is an open, vendor-neutral, industry-standard application protocol for accessing and maintaining distributed directory information services over an IP network. In simpler terms, it is the underlying language that allows different systems and applications to communicate with a central directory to find information about users, devices, and permissions. Think of LDAP as a highly organized, digital phonebook. When an application needs to know if "John Doe" is a valid user and what his password is, it uses LDAP to ask the phonebook. How LDAP Organizes Data Unlike traditional relational databases (like SQL) that store data in tables, LDAP stores data in a hierarchical, tree-like structure known as the Directory Information Tree (DIT) . This makes it incredibly fast at reading and searching for information, which is exactly what an authentication system needs to do millions of times a day. Here are the core components of this structure: Root: The top level of the directory tree, usually representing the organization (e.g., dc=example, dc=com ). Branches (Organizational Units - OU): Categories or departments within the organization (e.g., ou=Marketing , ou=Servers ). Leaves (Entries): The actual objects being stored, such as a specific user, printer, or computer. Attributes: The specific pieces of data tied to an entry. For a user entry, attributes might include givenName (first name), mail (email address), and userPassword . Every entry in an LDAP directory has a unique identifier called a Distinguished Name (DN) . It acts like an absolute file path. For example, John Doe’s DN might look like this: cn=John Doe, ou=Marketing, dc=example, dc=com How Applications Talk to LDAP When an

No hacking — a passive scan only looks at what your browser already downloads when it opens a page. Here's what I found: 6 of 15 load their Supabase database directly client-side. The public API key sits in the page source. That's fine if Row-Level Security is configured right — but it's one wrong setting away from "anyone can read the whole table." 14 of 15 ship no Content-Security-Policy — a simple, high-value hardening against script injection, almost always missing. Is this theoretical? No. Two apps I audited with the owner's permission: A social app: the profiles table — user names, cities, and a password hash — readable by a logged-out stranger. Closed in an afternoon. A paid learning app: 155 paid study sheets and 4,872 answers were readable by anyone, with no account and no subscription — its entire paid catalogue, a single API call away. The paywall lived only in the front-end; the database served everything to everyone. Loading Supabase in the browser isn't the mistake. Not enforcing access in the database (RLS) is. And the tools you build with won't tell you — they'll happily ship it. If you built something on Lovable / Bolt / Replit with real users (or paying ones), it's worth 60 seconds to check what a stranger can already see. I made a free tool that runs the surface check (passive, no signup): sealdy.dev Happy to answer questions on how RLS leaks happen and how to lock them down.

For years, scam prevention has relied on a familiar instruction: educate people so they can recognise danger before they act. Public campaigns warn consumers not to click unexpected links, disclose security codes, transfer money under pressure, or trust unsolicited contact. This advice remains useful, but it places too much defensive responsibility at the final point in a long scam chain. The Australian Scams Prevention Framework, or SPF, reflects a more demanding view. The framework requires selected service providers to take action against scams connected with or using their services. Its governing logic extends across prevention, detection, reporting, disruption, response, governance and intelligence sharing.[1][2] Australia has therefore moved beyond a model in which awareness is treated as the primary control. The emerging standard is an operational system in which institutions must identify scam activity, convert reports into usable intelligence, intervene against infrastructure, assist affected consumers and learn from recurring campaigns. This distinction is important. Awareness changes what a person knows. Operational scam defence changes what a scammer can do. Awareness Operates at the Last Defensible Moment Most awareness controls activate immediately before the victim acts. A warning appears before a transfer, a browser displays a suspicious-site alert, or a public campaign advises the consumer to pause and verify. By that stage, however, the scam may already have passed through several successful phases: The victim has been reached through SMS, email, social media, a search advertisement, a phone call or a marketplace conversation. A trusted brand, institution, employer, government agency or personal identity has been impersonated. The scammer has created urgency, authority, fear, opportunity or emotional dependency. The victim has been moved to a website, app, private chat or phone conversation. Payment, credential, identity or access pressure has begu

OpenBSD Privilege Escalation, GitHub AI Agent Leaks, & CDN Supply Chain Risks Today's Highlights This week's top security news features a critical use-after-free vulnerability in OpenBSD, a novel prompt injection attack leading to private repo leaks from GitHub's AI agent, and an unusual case of obfuscated bash scripts delivered via a CDN on consumer products. OpenBSD has a use-after-free allowing local privilege escalation to root (Hacker News) Source: https://nvd.nist.gov/vuln/detail/cve-2026-57589 A newly disclosed vulnerability, CVE-2026-57589, impacts OpenBSD, a renowned security-focused operating system. The vulnerability is identified as a use-after-free (UAF) flaw, which typically occurs when a program attempts to use memory after it has been freed, often leading to crashes or arbitrary code execution. In this specific case, the UAF bug allows for local privilege escalation to root. This type of vulnerability is particularly critical for operating systems, as it can enable an unprivileged attacker with local access to gain complete control over the system. System administrators and users of OpenBSD are advised to monitor official channels for patches and apply them immediately to mitigate the risk of compromise. Understanding the underlying cause of such UAFs is crucial for developing more robust memory management practices and identifying similar vulnerabilities in other systems. Comment: This is a critical reminder for OpenBSD admins to patch immediately, as use-after-free exploits are a classic, dangerous route to full system compromise from local access. GitLost: We Tricked GitHub's AI Agent into Leaking Private Repos (Hacker News) Source: https://noma.security/blog/gitlost-how-we-tricked-githubs-ai-agent-into-leaking-private-repos/ Researchers have uncovered a significant AI-specific security vulnerability, dubbed 'GitLost,' demonstrating how GitHub's AI agent can be manipulated to leak sensitive information from private repositories.

The cyberattack targeting a U.S. insurance giant is the largest known breach of driver's license numbers so far in 2026.

Last week, national security agencies from the Five Eyes—that’s the rich, English-language-speaking countries club—jointly released a statement warning of the increasing cyber risks of AI models: in particular, their ability to autonomously hack into systems and networks. The statement was more measured than some of the breathless headlines about it, and the advice they gave is pretty much the standard advice everyone gives—albeit with newfound urgency. Internet risks are nothing new, and cyberattacks—both large and small—have been a significant issue since long before the current crop of generative AI models...

Disclaimer: I'm currently learning web security through OWASP and PortSwigger Web Security Academy. These are my beginner-friendly notes rewritten as a blog to help reinforce my understanding. If you're just starting out, I hope this makes the topic easier to understand. What you'll learn: In this article you'll learn: ✔ What Broken Access Control is ✔ Vertical Privilege Escalation ✔ Security by Obscurity ✔ Parameter-Based Access Control ✔ Platform Misconfiguration ✔ Horizontal → Vertical Escalation ✔ IDOR ✔ Lessons learned from PortSwigger labs Concept Map: What is Broken Access Control? Broken Access Control happens when a user is able to access data, pages, or perform actions that they are not supposed to . Why should you care? Broken Access Control has ranked #1 in the OWASP Top 10 (2021) because it can expose sensitive data, allow privilege escalation, and let attackers perform actions they should never be able to perform. Think of a website with two types of users: Normal User Admin A normal user should only be able to view their own profile and perform basic actions. An admin, however, can manage users, delete accounts, change settings, etc. If a normal user somehow gains access to those admin features, that's Broken Access Control . In interview terms: Broken Access Control is the failure to properly enforce authorization, allowing users to perform actions beyond their intended permissions. 1. Vertical Privilege Escalation Vertical Privilege Escalation means moving up the permission hierarchy. Example: Normal User ↓ Admin A normal user should never be able to become an administrator. 1.1 Unprotected Functionality One of the simplest forms of Broken Access Control is Unprotected Functionality . Imagine a website has an admin page: /admin The developer removes the Admin button from the normal user's dashboard. Problem solved? No. If a user manually visits: /admin and the server doesn't verify whether they're actually an admin, the page opens. The mistake here

Introduction AI governance is often framed around risk, ethics, safety, and international cooperation. These are essential, but they are not sufficient. Governance only becomes real when countries have the computing infrastructure required to run, monitor, and maintain modern AI systems. Without compute, governance is theory. With compute, governance becomes capability. This article explores the missing execution layer in global AI governance — and why bridging the AI divide requires far more than policy alignment. The Hidden Dependency: Governance Assumes Infrastructure Most governance frameworks implicitly assume that nations already have: access to high performance compute reliable data pipelines secure storage operational tooling energy capacity connectivity skilled operators But this assumption is false for the majority of the world. The global AI divide is not primarily about access to models. It is about access to the infrastructure required to run them. Governance frameworks that ignore this reality risk becoming aspirational rather than actionable. The Execution Layer: Where Policy Meets Reality The execution layer is the part of AI governance that turns policy into practice. It includes: compute infrastructure data ingestion and processing pipelines monitoring and evaluation tooling human in the loop operational workflows maintenance and lifecycle management energy and cooling requirements secure deployment environments This layer is rarely discussed in governance conversations, yet it is the foundation upon which all responsible AI depends. Without an execution layer, governance collapses into paperwork. The Real Global Divide Isn’t About Models — It’s About Compute There is a persistent misconception that the AI divide is about access to large models. In reality, the divide is driven by: insufficient compute unreliable infrastructure lack of operational capacity limited data availability absence of secure environments dependency on external providers A c

Beyond the Playbook: Architecting Defenses Against Autonomous AI Threats We used to build security systems assuming the attacker was human. That assumption just died. Recent research demonstrations involving autonomous AI agents, such as "JadePuffer", have shown how quickly this shift is happening: an autonomous system independently compromised an unsecured Langflow instance, corrected failed authentication attempts, escalated privileges, exfiltrated credentials, and deployed ransomware — all without human intervention. This is not a one-off curiosity. It marks the beginning of a fundamental change in the threat landscape. Recent research demonstrations involving autonomous AI agents, such as "JadePuffer", have shown how quickly this shift is happening: an autonomous system independently compromised an unsecured Langflow instance, corrected failed authentication attempts, escalated privileges, exfiltrated credentials, and deployed ransomware. All without human intervention. This is not a one-off curiosity. It marks the beginning of a fundamental change in the threat landscape. From Static Playbooks to Autonomous Attackers Traditional ransomware follows predictable patterns. A script runs through a fixed playbook: scan, encrypt, demand ransom. If one step fails, the attack often stalls. Autonomous AI agents operate differently. They analyze their environment in real time, adapt when initial attempts fail, make contextual decisions about targets and techniques, and chain multiple exploits together without predefined sequences. This introduces machine-speed lateral movement. Something human defenders and traditional security tools are not built to handle. The Defensive Automation Gap The core problem is asymmetry. Attackers are rapidly automating both reconnaissance and execution. Defenders, on the other hand, still rely heavily on manual processes, static rules, and human-driven response. This "Defensive Automation Gap" creates dangerous imbalances in speed, scale, an

Originally published on satyamrastogi.com Seqrite Labs identifies multi-stage DcRAT campaign impersonating India's Income Tax Department. Attackers exploit tax professional workflows to deliver remote access trojans capable of data exfiltration and lateral movement. Operation DragonReturn: DcRAT Deployment via Fake ITR Utilities Executive Summary A China-nexus threat cluster is actively exploiting the predictable workflows of Indian tax professionals, corporate finance teams, and individual taxpayers through phishing campaigns distributing DcRAT (Dark Crystal Remote Access Trojan). Operation DragonReturn, as tracked by Seqrite Labs, demonstrates sophisticated understanding of Indian taxation cycles and organizational structures - critical operational intelligence required for high-success-rate social engineering. From an attacker's perspective, this campaign is methodologically sound: it targets a specific, predictable event (tax filing deadlines), uses trusted entity impersonation (Income Tax Department), and deploys a mature RAT with established evasion capabilities. The selection of DcRAT indicates access to commodity malware-as-a-service (MaaS) infrastructure, likely from Chinese underground forums where such tools are actively monetized and continuously updated. Attack Vector Analysis This operation chains multiple MITRE ATT&CK techniques into a cohesive infection chain: Initial Compromise: Spear-Phishing with Pretexting Attackers execute T1566.002 (Phishing - Spearphishing Attachment) by crafting emails impersonating legitimate Indian Income Tax Department communications. The social engineering layer leverages T1598.003 (Phishing - Spearphishing Link) with URLs pointing to malicious tax filing utilities. Pretexting is enhanced through T1589.001 (Gather Victim Identity Information - Credentials) , as attackers likely harvested tax professional contact lists from public records, LinkedIn OSINT, or previous data breaches. The timing of campaigns around Indian fis

Meses atrás eu estava fazendo uma varredura de segurança no sistema multi-tenant da minha empresa, procurando vulnerabilidades. Afinal, já é um sistema que conta com diversos usuários e que a cada mês vem crescendo mais. Cyber security não é a minha área, então pedi um relatório com todos os achados pro nosso querido amigo Fable 5. O primeiro item veio destacado em vermelho, caixa alta, com a categoria mais grave possível: BOLA (Broken Object Level Authorization). Eu nunca tinha visto esse termo, e ele estava registrado como uma falha grave que eu nem sabia que existia. O sistema nasceu antes do advento da IA escrever código do jeito como faz hoje. Começou comigo codando na mão; meu foco era fazer funcionar para melhorar depois. Com a chegada da IA, parei de escrever código e passei a revisar e garantir qualidade. Só que, naquele relatório, eu não entendia metade dos erros listados. Não conhecia os nomes e muito menos sabia por que eram tão graves. E aí me caiu a ficha: eu sou um legítimo impostor. (Pelo menos era o que eu pensava e sentia.) Escrever código era onde eu sentia o esforço, a prova concreta de estar construindo algo com a minha criatividade. Como o Brooks escreve em O Mítico Homem-Mês: "a programação é divertida, porque satisfaz anseios criativos acalentados profundamente dentro de nós". Minha prioridade era resolver o problema, mas, pra resolver, eu tinha que entender onde estava pisando. O que é esse tal BOLA, e por que é tão grave? Este artigo é o que eu descobri. O que é BOLA A OWASP, que mantém a lista das falhas de segurança de API mais críticas, coloca o BOLA em primeiro lugar no ranking de 2023: a mais comum e a mais fácil de explorar. Ou seja, está em todo lugar e não exige um gênio pra abusar. A ideia central é simples. Toda vez que uma API recebe o ID de um objeto e faz alguma coisa com ele, seja POST, GET, DELETE ou o que for, ela precisa checar uma pergunta antes de responder: o usuário logado tem permissão pra acessar este objeto específic
