A Couple of Rats Pick Up New Tricks, Un Proposes Cybercrime Treaty
In this episode of the Microsoft Threat Intelligence Podcast host Sherrod DeGrippo is joined by Microsoft’s Dinesh Natarajan, Senior Threat Hunter, and Thomas Ball, Senior Security Researcher. They unpack recent findings around AsyncRAT, a remote access Trojan (RAT) used for keylogging, data exfiltration, and deploying further malware.
Dinesh explains how attackers are now using screen-sharing tools, like Screen Connect, as part of a new infection chain that makes the malware delivery process more deceptive. Thomas then shares insights on SectopRAT, another threat targeting browser data and crypto wallets. Uniquely, this RAT creates a second desktop, allowing attackers to operate undetected.
Next, Sherrod talks with Microsoft’s Senior Director of Diplomacy, Kaja Ciglic, about the UN’s proposed cybercrime treaty. Originally spearheaded by Russia, the treaty aims to create a global framework for prosecuting cybercrime, but critics worry about its potential impact on freedom of expression and human rights.
In this episode you’ll learn:
How tech support scam emails lead to AsyncRAT installations on different devices
The importance of leveraging tools like Microsoft Defender's SmartScreen for protection
The treaty encourages cooperation but may let governments exploit unclear cybercrime definitions
Some questions we ask:
How does social engineering through email play a role in these attacks?
What capabilities does AsyncRat have, and why is it so concerning?
How do we ensure the treaty doesn't impact freedom of expression or human rights?

Between Two Gregs: An Update on the North Korean Threat Landscape
In this episode of the Microsoft Threat Intelligence Podcast host Sherrod DeGrippo is joined by Proofpoint’s Greg Lesnewich and Microsoft’s Greg Schloemer to share the unique threat posed by North Korea’s (DPRK) state-sponsored cyber activities. The Gregs discuss their years of experience tracking North Korean cyber actors and the distinct tactics that set DPRK apart from other nation-sponsored threats. The conversation also explores North Korea’s high stakes, as DPRK threat actors operate under intense pressure from government handlers, adding a layer of urgency and fear to their operations. They share insights into North Korea’s aggressive use of stolen cryptocurrency to fund the regime’s initiatives, like ballistic missile tests, and discuss the broader geopolitical impact.
In this episode you’ll learn:
The technical sophistication and the relentlessness of DPRK cyber tactics
Complex motives behind funding and sustaining the North Korean government
The training and skills development of North Korean cyber operators
Some questions we ask:
How do North Korean threat actors set up their relay networks differently?
What sets North Korea apart from other nation-sponsored threat actors?
How do North Korean cyber actors differ from traditional e-crime actors?
