Deral Heiland explores from printer to pwnd at DEF CON 19, examining wireless-security and practical defenses.

Summary

Architecture and Background

Deral Heiland - From Printer To Pwnd: Leveraging Multifunction Printers During Penetration Testing In this presentation we go beyond the common printer issues and focus on harvesting data from multifunction printer (MFP) that can be leveraged to gain access to other core network systems. By taking advantage of poor printer security and vulnerabilities during penetration testing we are able to harvest a wealth of information from MFP devices including usernames, email addresses, and authentication information including SMB, Email, LDAP passwords.

Vulnerability Analysis

Leveraging this information we have successful gained administrative access into core systems including email servers, file servers and Active directory domains on multiple occasions. We will also explore MFP device vulnerabilities including authentication bypass, information leakage flaws.

Exploitation and Demonstrations

Tying this altogether we will discuss the development of an automated process for harvesting the information from MFP devices with the updated release of our tool 'PRAEDA'. Deral Heiland CISSP, serves as a Senior Security Engineer where he is responsible for security assessments, and consulting for corporations and government agencies.

Remediation and Defensive Strategies

In addition, Deral is the founder of Layered Defense Research a group of security professionals responsible for discovering and publishing multiple vulnerabilities. Deral is also co-founder and president of Ohio Information Security Forum a not for profit organization that focuses on information security training and education. Deral has also presented at numerous conferences including ShmooCon, DEF CON, AFCEA InfoTech, Ohio Digital Government Summit , University of Wisconsin lockdown conference and has also been a guest lecturer at the Airforce Institute of Technology (AFIT). Deral has over 18 years of experience in the Information Technology field, and has held multiple positions including: Senior Network Analyst, Network Administrator, Database Manager, Financial Systems Manager and Senior Information Security Analyst where he was responsible for delivering security guidance and leadership in the area of risk and vulnerability management for a global Fortune 500 manufacturer.
