In this month’s “Red Team Hacking” feature, you will learn how to use Chisel to access restricted intenal network of our target organization. Let’s start with what chisel is. What is Chisel? Chisel is a traffic tunneller that can tunnel SSH traffic over HTTP. It is mainly useful in Red Team operations and pen test exercises to bypass firewall restrictions, forward remote ports, SOCKS proxy etc. In this Issue, we will show you how to access the restricted internal network and resources of target organization using Chisel. Scenario Imagine you are in midst of a pen test or a Red Team operation. You have already gained initial access on a system belonging to the organization. While scanning the internal network for pivoting purposes, you find a web server that is…

A critical file deletion vulnerability has been discovered in the popular plugin of WordPress that affects over 6,00,000 active installations. Forminator is a Wordpress from builder plugin that is used to create forms, surveys etc for Wordpress websites. About the vulnerability The vulnerability tracked as CVE-2025-6463 has a vulnerability rating of 8.8. It allows unauthenticated attackers to delete any critical system files including “wpconfig.php” and can lead to remote code execution and even complete site takeover. This vulnerability affects all versions of Forminator plugin up to 1.44.2. The vulnerability is due to an insufficient file path validation in the “entry_delete_upload_files” function. This function processes form submission deletions as it doesn’t perform proper security checks. It processes all metadata values without verifying files types, the extension of the file, or the…

Some unusual witnesses helped convict Alex Murdaugh of the murders of his wife, Maggie, and son, Paul. The first was Bubba, Maggie’s yellow Labrador retriever. Prosecutors used a recording of Bubba to place Alex at the site of the murders. Given Alex’s presence at the crime scene, other witnesses then revealed his movements, tracked his speed and explained what he had in his hands. Those other witnesses were a 2021 Chevy Suburban and Maggie, Paul and Alex’s cellphones, which all provided data. They’re all part of the Internet of Things, also known as IoT. The privacy implications of devices connected to the internet are not often the most important consideration in solving a murder case. But outside of criminal prosecution, they affect people’s privacy in ways that should give everyone…

A critical zero-day vulnerability has been discovered affecting Microsoft SharePoint Servers installed on the on-premises installations which was being exploited by threat actors in the wild before its detection. About the vulnerability The vulnerabilities tracked as CVE-2025-53770 and CVE-2025-53771, with a CVSS rating of 9.8 is a result of deserialization of untrusted data flaw within the SharePoint server.
