Practical security insights for teams without a SOC

A CORS misconfiguration occurs when a web application allows an untrusted origin to read cross-origin responses that should only be available to trusted websites. Common causes include reflecting arbitrary Origin values, weak origin validation, trusting null, or allowing origins that attackers can control.Not every permissive CORS response is an exploitable vulnerability. The real risk depends […]

Cross-Site Request Forgery (CSRF) is a web security vulnerability in which an attacker causes a user’s browser to send an unintended request to an application that accepts the user’s automatically supplied credentials or authority. The browser may be authenticated, but the application fails to verify that the user actually intended the action.That distinction is the […]

A WordPress pharma hack is a post-compromise SEO spam infection that adds pharmaceutical keywords, links, pages, redirects, or hidden content to a WordPress website without the owner’s permission. It is also commonly called a Viagra hack, pharmaceutical spam hack, or pharma SEO spam.The infection can be confusing because the website may look normal when you […]

An open redirect vulnerability occurs when a web application lets attacker-controlled input determine where a user is redirected without sufficiently restricting the final destination. An attacker can then create a link that begins on a legitimate domain but sends the victim to an external site chosen by the attacker.The simplest impact is phishing: the trusted […]

Server-Side Request Forgery (SSRF) is a web application security vulnerability in which attacker-controlled input causes a server-side component to send a network request to an unintended destination. The defining characteristic is that the sensitive request originates from the server, not from the attacker’s browser.That distinction matters because an application server may be able to reach […]

Cross-site scripting (XSS) is a web application vulnerability that allows untrusted data to reach a browser in a context where the browser interprets it as executable code instead of ordinary content. The attacker does not need to compromise the browser itself. The vulnerable website delivers or processes the attacker-controlled content in a way that makes […]

A Magecart attack steals payment and personal data from ecommerce customers by compromising the website, its checkout code, or software that the page trusts. The best-known Magecart technique uses malicious JavaScript to watch a payment form in the customer’s browser, copy card data as it is entered, and send a stolen copy to attacker-controlled infrastructure […]

WordPress vs Drupal security is not as simple as comparing vulnerability counts. Drupal generally provides stronger security and governance defaults for complex, multi-user websites, especially around permissions, configuration management, and controlled deployments. WordPress core also has a mature security process and stronger native update automation, but its enormous plugin and theme ecosystem creates more third-party […]

A JavaScript npm supply chain attack targets the software and infrastructure between an npm package maintainer and the application that eventually installs that package. Instead of exploiting a flaw in your own JavaScript first, an attacker may compromise a trusted package, publish a lookalike dependency, abuse package resolution, steal publishing credentials, or execute malicious code […]

If you want to know how to scan JavaScript for vulnerabilities, do not rely on a single security check. A modern JavaScript application can contain weaknesses in the code your team writes, known vulnerabilities in npm dependencies, and security issues that appear only after the application runs in a browser. A useful JavaScript security assessment […]

If you want to know how to scan an IP address for vulnerabilities, the process goes beyond checking whether a few ports are open. A proper assessment verifies the correct and authorized target, identifies reachable TCP and relevant UDP services, fingerprints the software behind them, runs vulnerability-specific checks, validates important findings, prioritizes confirmed weaknesses, applies […]
