Alon Zahavi from CyberArk, joins Dave Bittner on this episode to discuss CyberArk's work in conjunction with Patch Tuesday. CyberArk published about how Docker inadvertently created a new vulnerability and what happens when it's exploited.

CyberArk's research concluded that an attacker may execute files with capabilities or setuid files in order to escalate its privileges up to root level. CyberArk found the new vuln in some of Microsoft’s Docker images, caused by misuse of Linux capabilities, a powerful additional layer of security that gives admins the ability to assign capabilities and privileges to processes and files in the Linux system

Larry Cashdollar, Principal Security Intelligence Response Engineer from Akamai Technologies, joins Dave to talk about their research on "KmsdBot: The Attack and Mine Malware." Akamai's Security Research team has found a new malware that infected their honeypot, which they have dubbed KmsdBot. 

The research states "The malware attacks using UDP, TCP, HTTP POST, and GET, along with a command and control infrastructure (C2), which communicates over TCP." The botnet targets weak login credentials and then infects systems via an SSH connection.

Deepen Desai from Zscaler sits down with Dave to talk about the Crytox ransomware family. First observed in 2020, Crytox is a ransomware family consisting of several stages of encrypted code that has fallen under the radar compared to other ransomware families. While other groups normally use double extortion attacks where data is both encrypted and held for ransom, Crytox does not perform this way.

The research says "The modus operandi of the group is to encrypt files on connected drives along with network drives, drop the uTox messenger application and then display a ransom note to the victim." It also shares how you may be compromised with this ransomware and goes through each stage in depth.

Roya Gordon from Nozomi Networks sits down with Dave to discuss their work "UWB Real Time Locating Systems: How Secure Radio Communications May Fail in Practice." Ultra-wideband (UWB) is a rapidly-growing radio technology that, according to the UWB Alliance, is forecasted to drive sales volumes exceeding one billion devices annually by 2025.

In an effort to strengthen the security of devices utilizing UWB, Nozomi Networks Labs conducted a security assessment of two popular UWB RTLS solutions available on the market. Their research reveals 0-day vulnerabilities and other weaknesses that, if exploited, could allow an attacker to gain full access to all sensitive location data exchanged over-the-air.

Federico Kirschbaum from Faraday Security sits down with Dave to discuss their research on "A vulnerability in Realtek's SDK for eCos OS: pwning thousands of routers." The team at Faraday found a vulnerability that made it to DEFCON 30, labeling it high severity. With more and more people working from home for their companies, the research team went looking for where there may be vulnerabilities as employees are working from home.

The research states that the team was "seeking and reporting security vulnerabilities in IoT devices, which led to the finding of an exploitable bug in a consumer-grade router popular in Argentina." They also stated in the research that it was escalating quickly and shares about how protecting home networks is important while working remotely.

Dick O'Brien from Symantec's Threat Hunter team sits down with Dave to discuss their work on "Witchetty - Group Uses Updated Toolset in Attacks on Governments in Middle East." Their research has found that the group known as Witchetty aka LookingFrog, has been progressively updating its toolset, including the new tool, backdoor Trojan (Backdoor.Stegmap) to launch malware attacks on targets in the Middle East and Africa.

The research states "The attackers exploited the ProxyShell and ProxyLogon vulnerabilities to install web shells on public-facing servers before stealing credentials, moving laterally across networks, and installing malware on other computers. The researchers describe more on the new tool being used and why this new group is a threat.

Brigid O Gorman from Symantec's Threat Hunter team joins Dave to discuss their research on "Noberus Ransomware - Darkside and BlackMatter Successor Continues to Evolve its Tactics." The research states that Noberus ransomware (aka BlackCat, ALPHV) is more dangerous than ever because attackers have been using new tactics, tools, and procedures in recent months.

In the research, Symantec says, "Among some of the more notable developments has been the use of a new version of the Exmatter data exfiltration tool, and the use of Eamfo, information-stealing malware that is designed to steal credentials stored by Veeam backup software." They go over an in-depth look at how its affiliate program operates.

Jen Miller-Osborn from Palo Alto Networks' Unit 42 joins Dave to discuss their work on the Cloaked Ursa group, with a recent report released called "Russian APT29 Hackers Use Online Storage Services, DropBox and Google Drive." The research shares insights into an active campaign from Russia’s Foreign Intelligence Service, that is leveraging the use of trusted, legitimate cloud services including Google Drive as a staging platform to deliver malware.

The research states that when these tactics are used, it is extremely difficult for organizations to detect the malicious activity in connection with the campaign. These tactics are used to collect victim information, evade detection, and deliver Cobalt Strike.

David Prefer from SANS sits down with Dave to discuss how a new covert channel exfiltrates data via a browser's built-in bookmark sync. David goes on to describe how this research will "describe how the ability to synchronize bookmarks across devices introduces a novel vector for data exfiltration and other misuses."

In the research, he shares how he tested his said hypothesis and goes on to describe how the interesting find was tested on multiple browsers including Chrome, Edge, Brave and Opera. In his research, he found that bookmarks are able to keep data and synchronize it, making it easier to infiltrate and extract data from. David shares the rest of his findings, as well as what organizations and browser developers can do to work on this new threat.

Gafnit Amiga, Director of Security Research from Lightspin, joins Dave to discuss her team's research "AWS RDS Vulnerability Leads to AWS Internal Service Credentials." The research describes how the vulnerability was caught and right after it was reported, the AWS Security team applied an initial patch limited only to the recent Amazon Relational Database Service (RDS) and Aurora PostgreSQL engines, excluding older versions.

They followed by personally reaching out to the customers affected by the vulnerability and helped them through the update process. The research states "Lightspin's Research Team obtained credentials to an internal AWS service by exploiting a local file read vulnerability on the RDS EC2 instance using the log_fdw extension."
