Integrating Turnstile with the Cloudflare WAF to challenge fetch requests

Two months ago, we made Cloudflare Turnstile generally available — giving website owners everywhere an easy way to fend off bots, without ever issuing a CAPTCHA. Turnstile allows any website owner to embed a frustration-free Cloudflare challenge on their website with a simple code snippet, making it easy to help ensure that only human traffic makes it through.

Navigating the Cybersecurity Horizon in 2024

In 2023, organizations faced a surge in ransomware attacks, prompting a reevaluation of cybersecurity readiness. The focus on high-value assets and critical infrastructure indicated an escalating threat landscape, demanding stronger preemptive measures. This trend is expected to continue in 2024 as cybercriminals exploit vulnerabilities.

Apache Struts 2 Remote Code Execution (CVE-2023-50164) - Cato's Analysis and Mitigation

By Vadim Freger, Dolev Moshe Attiya On December 7th, 2023, the Apache Struts project disclosed a critical vulnerability (CVSS score 9.8) in its Struts 2 open-source web framework. The vulnerability resides in the flawed file upload logic and allows attackers to manipulate upload parameters, resulting in arbitrary file upload and code execution under certain conditions. There is no known workaround, and the only solution is to upgrade to the latest versions, the affected versions being.

Implementing tenant isolation in multi-tenant Kubernetes clusters

One recurrent point in our first interaction with Kubernetes users is the difficulty of implementing security controls on their Kubernetes clusters where tenant or workload isolation is required during rollout or runtime. This happens due to one of the following reasons: Calico provides several features and capabilities to cover each one of the above points with Policy Recommendation, Policy Board, and Dynamic Service and Threat Graph.

SOC Efficiency is the New Imperative

The cybersecurity landscape is currently undergoing significant changes. Many organizations have followed the guidance of analysts by investing in top-of-the-line products and solutions. However, they are now facing unexpected challenges. These challenges include steep financial burdens, a lack of the expected return on investment, and the persistent ability of hackers to breach their security defenses.

Why you should use rotating proxies for web scraping

Because data is an invaluable asset in an increasingly digitized world, companies are trying to get a competitive edge by acquiring data sets that can provide crucial insights. While big players utilize machine learning and Big Data, these technologies might be off-limits or too expensive for some companies. One of the most affordable alternatives to traditional Big Data research is web scraping, a technique of extracting data from websites through software. It is estimated that the web scraping industry has already surpassed $4 billion and is projected to reach $16 billion by 2035.
