Research Saturday

Guest Tom Roter from Minera Labs joins Dave to discuss his team research: "Rigging a Windows Installation." It is common knowledge that pirated software might contain malware, yet millions still put themselves and their devices at risk and download from dubious sources. It is even more surprising to see the popularity of torrented operating system installations, which are ranked at the top of most...

Guest Yonatan Striem-Amit joins Dave to talk about Cybereason's research "Prometei Botnet Exploiting Microsoft Exchange Vulnerabilities."

Guest Brandon Hoffman of Intel 471 joins Dave Bittner to share his team's research "EtterSilent: the underground’s new favorite maldoc builder". The cybercrime underground often mimics behaviors that we see in everyday facets of life. Intel 471’s latest discovery is an example of one of these patterns: when a product takes off in the marketplace, users will rush to obtain it and find unique ways t...

Guest Joe Slowik joins us from DomainTools to discuss his team's research "COVID-19 Phishing With a Side of Cobalt Strike." Multiple adversaries, from criminal groups to state-directed entities, engaged in malicious cyber activity using COVID-19 pandemic themes since March 2020. Adversaries continue to leverage the pandemic, arguably the most significant issue globally as of this writing, in vario...

Guest LTC Erica Mitchell from Army Cyber Institute joins us to talk about their infrastructure resiliency research project called Jack Voltaic. The Army Cyber Institute’s (ACI’s) Jack Voltaic (JV) project enables the institute to study incident response gaps alongside assembled partners to identify interdependencies among critical infrastructure and provide recommendations. JV provides an innovati...

Guest Mike McLellan from Secureworks joins us to share his team's insights about SUPERNOVA and threat group attribution. Similarities between the SUPERNOVA activity and a previous compromise of the network suggest that SPIRAL was responsible for both intrusions and reveal information about the threat group. In late 2020, Secureworks® Counter Threat Unit™ (CTU) researchers observed a threat actor e...

Guest Jen Miller-Osborn from Palo Alto Networks' Unit 42 joins Dave to discuss their 2021 Unit 42 Ransomware Threat Report, which highlights a surge in ransomware demands based on a global analysis of the threat landscape in 2020. To evaluate the current state of the ransomware threat landscape, the Unit 42 threat intelligence team and the Crypsis incident response team collaborated to analyze the...

Guest Jason Passwaters of Intel 471 joins us to discuss his team's research into bulletproof hosting (BPH). The research team at Intel 471 defined what a typical BPH service offers and how these services can be stopped in order to limit the damage they have on enterprises, businesses and digital society itself. They examined some popular malware families that actors host or leverage via BPH servic...

Guest Deepen Desai joins Dave to talk about Zsaler's research "Return of the MINEBRIDGE RAT With New TTPs and Social Engineering Lures." In Jan 2021, Zscaler ThreatLabZ discovered new instances of the MINEBRIDGE remote-access Trojan (RAT) embedded in macro-based Word document files crafted to look like valid job resumes (CVs). Such lures are often used as social engineering schemes by threat actor...

Guests Gage Mele, Winston Marydasan, and Yury Polozov from Anomali join Dave to discuss their research into Static Kitten targeting government agencies in the UAE and Kuwait. Anomali Threat Research uncovered malicious activity very likely attributed to the Iran-nexus cyberespionage group, Static Kitten (Seedworm, MERCURY, Temp. Zagros, POWERSTATS, NTSTATS, MuddyWater), which is known to target nu...

Guests Fernando Martinez and Tom Hegel from AT&T Alien Labs join Dave to discuss their team's research "Malware using new Ezuri memory loader." Multiple threat actors have recently started using a Go language (Golang) tool to act as a packer and avoid Antivirus detection. Additionally, the Ezuri memory loader tool acts as a malware loader and executes its payload in memory, without writing the fil...

Guest Sergio Caltagirone from Dragos joins us to take us through their 2020 ICS Cybersecurity Year in Review report. Dragos's annual ICS Year in Review provides an overview and analysis of ICS vulnerabilities, global threat activity targeting industrial environments, and industry trends and observations gathered from customer engagements worldwide. The goal of the report is to give asset owners an...

Guest Jen Miller-Osborn from Palo Alto Networks' Unit 42 joins us to discuss their research into BendyBear. Highly malleable, highly sophisticated and over 10,000 bytes of machine code. The code behavior and features strongly correlate with that of the WaterBear malware family, which has been active since as early as 2009. The malware is associated with the cyber espionage group BlackTech, which m...

Guest Dr. Rosario Cammarota from Intel Labs joins us to discuss confidential computing. Confidential computing provides a secure platform for multiple parties to combine, analyze and learn from sensitive data without exposing their data or machine learning algorithms to the other party. This technique goes by several names — multiparty computing, federated learning and privacy-preserving analytics...

Guest Hossein Jazi of Malwarebytes joins us to take a deep dive into North Korea's APT37 (aka ScarCruft, Reaper and Group123) toolkit. On December 7 2020 the Malwarebytes Labs threat team identified a malicious document uploaded to Virus Total which was purporting to be a meeting request likely used to target the government of South Korea. The meeting date mentioned in the document was 23 Jan 2020...

Guest Maurits Lucas from Intel471 joins us to discuss his team's research into cybercrime in China. Data from Intel 471 show that the Chinese cybercrime underground proliferates through use of common methods or platforms, but behaves differently in large part due to the caution that actors take with regard to their identity. While the average citizen must follow the heavy handed nature of the gove...

Guest Bojan Zdrnja of Infigo IS and a certified instructor at SANS Institute shares an incident he discovered where attackers were using a pretty novel way of exfiltrating data and using that channel for C&C communication. The code that was acquired was only partially recovered, but enough to indicate powerful features that the attackers were (ab)using in Google Chrome. The basis for this attack w...

Guest Dr. Shreyas Sen, a Perdue University associate professor of electrical and computer engineering, joins us to discuss the following scenario:. Instead of inserting a card or scanning a smartphone to make a payment, what if you could simply touch the machine with your finger? A prototype developed by Purdue University engineers would essentially let your body act as the link between your card...

Guest Joe Slowik joins us from Domain Tools to share their research "Current Events to Widespread Campaigns: Pivoting from Samples to Identify Activity" where they examined technical artifacts emerging around the 2020 conflict between Armenia and Azerbaijan in the Caucasus region.  Cyber Threat Intelligence (CTI) practitioners can gain insight into adversary operations by tracking conflicts or geo...

Guest Yonatan Striem-Amit joins us from Cybereason to share their Nocturnus Team research into Kimsuky. The Cybereason Nocturnus Team has been tracking various North Korean threat actors, among them the cyber espionage group known as Kimsuky, (aka: Velvet Chollima, Black Banshee and Thallium), which has been active since at least 2012 and is believed to be operating on behalf of the North Korean r...

Guest Mark Arena from Intel471 joins us to discuss his team's research into Trickbot and its evolution from a banking trojan to a long-standing, most likely well-resourced operation that was taken down last year. Mark shares some insight into Trickbot's order of operations and what went on behind the scenes that his team working with Brian Krebs were able to discover. Since the separate and indepe...

Guest Selena Larson, senior cyber threat analyst at Dragos, Inc., joins us to discuss their research into recent observations of ICS-targeting threats to manufacturing organizations.  Cyber risk to the manufacturing sector is increasing, led by disruptive cyberattacks impacting industrial processes, intrusions enabling information gathering and process information theft, and new activity from Indu...
