Tenable Research Podcast Tenable Research

This month we talked to Tenable’s director of research product management Ray Carney and Eric Hoffman, director of partnerships and alliances at Greynoise, about the formation of a new research alliance program.

Announced in mid October, this is intended to facilitate collaboration and information sharing between industry partners, and support best-practice coordinated vulnerability disclosure in order to promote increased cooperation in order to reduce an attacker's free time.

After we discussed the concept of Exposure Management on our last podcast, this time we welcome back Tenable’s senior principal security advocate Nathan Wenzler to discuss the concept of how you can determine your level of exposure, what has led to this level of vulnerability, and what options are available to you to better manage this.

The concept of Exposure Management has become more and more prominent in recent months, as users understand how much they are exposed to attack, how they can protect their assets and what it takes to achieve a level of compliance.


In this podcast, we talk with Tenable’s senior principal security advocate Nathan Wenzler about the concept of Exposure Management, what it is, and what businesses need to do to adopt it.

In the field of responsible disclosure, a policy of 90 days to publicly disclose vulnerabilities has been created by industry. This time period should allow the researcher to disclose the vulnerability to the recipient company, giving them time to push a fix out before the original flaw can be announced.


However are we in a time where this time period still works? Some vulnerabilities can be fixed fairly rapidly as we work in cloud environments, while others can be more challenging to fix - such as in OT. We talked to Tenable’s Ivan Belyna and Nick Miles about the evolution of the 90 day policy, and its present and future, and what use advanced disclosure is to security leaders and to the wider industry.

In the first few months of 2022, the LAPSUS$ Group made a major splash in the cybersecurity headlines as it conducted a series of attacks on the likes of Nvidia, Microsoft and Okta. However a few months later, they had disappeared and arrests were reported soon afterwards.


In a new blog, Tenable’s senior research engineer Claire Tills looked at the efforts of LAPSUS$ and what its motivations were, and how it is viewed now, and joins us on this podcast to discuss the extortion group further.

Beyond the success of its impact, a lucrative criminal ecosystem has been developed for ransomware. This has seen ransomware-as-a-service (RaaS) creating an ecosystem utilizing multiple players, while the concept of double extortion has emerged, which involves exfiltrating data from victim organizations and publishing teasers about these breaches on the dark web.


In this new edition of the Tenable Research podcast, we talk with senior staff research engineer Satnam Narang about a new white paper which explores the working of this ecosystem, how it works and what the economics of the model are.
