Multiple vulnerabilities in eLinkSmart padlocks
Multiple vulnerabilities were found in the eLinkSmart smart lock range. Flaws in the implementation of the locks' Bluetooth Low Energy (BLE) communication and the back-end API enable an attacker to unlock any lock within Bluetooth range, identify the location of any lock in the world, and compromise user credentials. This blog post describes the vulnerabilities, as well as the process followed to identify them, and demonstrates the issues in action.

Bug hunting with static code analysis
Static code analysis techniques can improve application security by identifying vulnerabilities early in the software development lifecycle. The presentation explores automated methods for detecting security flaws, ranging from simple scripts to sophisticated analysis tools. These techniques can be integrated into continuous integration systems to proactively catch and resolve security issues before product release.

Abusing PuTTY & Pageant through native functionality
A technique for remotely interacting with SSH keys stored in PuTTY's Pageant SSH agent on Windows is explored. The method leverages native functionality to proxy SSH authentication requests through a compromised workstation without traditional exploitation. An attack tool called PageantJacker enables forwarding authentication requests to a remote Pageant instance, allowing an attacker to use a target's SSH keys from their own machine.

The Pageantry of Lateral Movement
A presentation on lateral movement techniques in network penetration testing explores abusing Pageant (PuTTY's SSH agent) on Windows hosts. The talk demonstrates a nearly undetectable method of tunneling SSH agent traffic using a meterpreter extension. Improvements were made to an existing reconnaissance tool to enhance its utility during simulated attacks.
