Office 365 Audit Logging and Email scams
We’re coming across more and more instances of Office 365 accounts with suspicious activity. Unfortunately the logging defaults in Office 365 are unsatisfactory and a little additional configuration is required to improve the effectiveness of the logging, especially in regards to user activity.
Microsoft DirectX Memory Corruption (CVE-2018-8563)
A memory corruption vulnerability exists in Microsoft DirectX. The corruption happens as a result of the incorrect handling of text, while running CSS tranformations, resulting in an out-of-bounds-read. It is possible to trigger this vulnerability remotely via Internet Explorer. An attacker can use this vulnerability to disclose memory of a victim’s machine. Generally, such vulnerability is chained with a Remote Code Execution vulnerability and used to bypass common defenses.
read moreAdventures with the Ducati CAN bus
In this article I’ll be taking a look at the CAN bus network in a 2009 Ducati 848. How to find the bus, confirm the high and low lines with a scope and analyse messages with a Linux box and socket-CAN. The aim of the game is to identify a way to get onto the bus, and then analyse the messages going across the bus. We’ll end up figuring out how to log the throttle position and RPM data, how the immobilizer is implemented and how to bypass it.
Extracting JavaScript from Sourcemaps
Sourcemaps are intended to make debugging minified JavaScript less of a pain. This article will take a closer look at Sourcemaps and discuss retrieving the original source code tree from a downloaded Sourcemap file.

Two vulnerabilities were discovered within the Oracle WebLogic SAML service provider authentication mechanism. By inserting an XML comment into the SAML NameID tag, an attacker can coerce the SAML service provider to log in as another user. Additionally, WebLogic does not require signed SAML assertions in the default configuration. By omitting the signature portions from a SAML assertion, an attacker can craft an arbitrary SAML assertion and bypass the authentication mechanism.

Phusion Passenger’s Nginx module is vulnerable to a privilege escalation vulnerability when run with a non-standard passenger_instance_registry_dir configuration. A vulnerability exists when creating the control_process.pid file, specifically when the file’s owner is changed from root. An attacker can use this behavior to escalate privileges from the www-data user to the root user when Nginx is restarted.
Red Team vs Pentest
When it comes to offensive security, engagements can be broadly broken up into two categories: Penetration testing and red teaming. Understanding the differences between the two is essential when attempting to verify the security of an application, network or organisation.
