Only Malware in the Building

Welcome in! You've entered, Only Malware in the Building. Join us each month to sip tea and solve mysteries about today's most interesting threats. Your host is ⁠⁠Selena Larson⁠⁠, ⁠⁠Proofpoint⁠⁠ intelligence analyst and host of their podcast ⁠⁠DISCARDED⁠⁠. Inspired by the residents of a building in New York's exclusive upper west side, Selena is joined by her co-hosts ⁠⁠N2K Networks⁠⁠ ⁠⁠Dave Bittner⁠⁠ and ⁠Keith Mularski⁠, former FBI cybercrime investigator and now Chief Global Ambassador at ⁠Qintel⁠. Being a security researcher is a bit like being a detective: you gather clues, analyze the evidence, and consult the experts to solve the cyber puzzle. On this episode, our hosts discuss Chinese-speaking threat actors are targeting Japan with a massive phishing campaign using a sneaky new kit called CoGUI, which has hit organizations with over 170 million messages in a single month. The campaign mimics trusted brands like Amazon, PayPay, and Rakuten to steal login and payment info—lining up with warnings from Japan's Financial Services Agency about attackers cashing out and buying Chinese stocks. While the CoGUI kit is slick with its evasion tricks and browser profiling, your hosts are hot on its trail with new detections to help stop the phishing frenzy.

Your host is ⁠Selena Larson⁠, ⁠Proofpoint⁠ intelligence analyst and host of their podcast ⁠DISCARDED⁠. Inspired by the residents of a building in New York's exclusive upper west side, Selena is joined by ⁠N2K Networks⁠ ⁠Dave Bittner⁠ and our newest co-host, Keith Mularski, former FBI cybercrime investigator and now Chief Global Ambassador at Qintel. Being a security researcher is a bit like being a detective: you gather clues, analyze the evidence, and consult the experts to solve the cyber puzzle. On this episode, our hosts discuss the growing trend of cybercriminals using legitimate remote monitoring and management (RMM) tools in email campaigns as a first-stage payload. They explore how these tools are being leveraged for data theft, financial fraud, and lateral movement within networks. With the decline of traditional malware delivery methods, including loaders and botnets, the shift toward RMMs marks a significant change in attack strategies. Tune in to learn more about this evolving threat landscape and how to stay ahead of these tactics.

Your host is Selena Larson, Proofpoint intelligence analyst and host of their podcast DISCARDED. Inspired by the residents of a building in New York's exclusive upper west side, Selena is joined by N2K Networks Dave Bittner —and our newest totally unbiased co-host, Archy, a highly sophisticated AI robot who swears they have no ulterior motives (but we're keeping an eye on them just in case). Being a security researcher is a bit like being a detective: you gather clues, analyze the evidence, and consult the experts to solve the cyber puzzle. On this episode, our hosts discuss Telephone-Oriented Attack Delivery (TOAD), also known as callback phishing. In this type of attack, an attacker sends a seemingly benign email, often containing an invoice or payment notification, along with a phone number. When the victim calls, they speak with the attacker, who convinces them to install remote access tools, leading to malware installation, phishing, and financial theft. Tune in as we explore how this deceptive tactic works and ways to protect yourself from falling victim to it.

On this episode, we dive into how Proofpoint researchers uncovered an espionage campaign casting custom malware known as "Voldemort" in August 2024. The Dark Arts practitioner behind this campaign targeted global organizations, disguising themselves as mundane tax authorities and weaving clever enchantments like using Google Sheets for command and control (C2). While their ultimate motive remains as shadowy as a cursed Horcrux, this malware is built for intelligence gathering and is primed to unleash additional attacks — likely summoning something even darker, like Cobalt Strike. Prepare your wands, and let's dive into this tale of digital sorcery!

On this episode, we talk about the abuse of legitimate services for malware delivery. Proofpoint has seen an increase in the abuse of tools like ScreenConnect and NetSupport, as well as Cloudflare Tunnel abuse and the use of IP filtering. They have also observed a rise in financially motivated malware delivery using TryCloudflare Tunnel abuse, focusing on remote access trojans (RATs) like Xworm and AsyncRAT. Today we look at how Cloudflare tunnels are used to evade detection and how they have evolved their tactics by incorporating obfuscation techniques, with ongoing research to identify the threat actors involved.

On this episode, we talk about "The curious case of the missing IcedID." IcedID is a malware originally classified as a banking trojan and was first observed in 2017. It also acts as a loader for other malware, including ransomware, and was a favored payload used by multiple cybercriminal threat actors until fall 2023. Then, it all but disappeared. In its place, a new threat crawled: Latrodectus. Named after a spider, this new malware, created by the same people as IcedID, is now poised to take over where IcedID melted off. Today we look back at what happened to the once prominent payload, and what its successor's spinning web of activity means for the overall landscape. Learn more about your ad choices.
