Hello to all our Cyber Panda Bears! In this extra-packed episode of Discarded, host Selena Larson and guest host, Sarah Sabotka reunite with Staff Threat Researcher Mark Kelly to dive deep into China-aligned espionage activity—this time with a focus on Taiwan’s semiconductor ecosystem and the strange, stealthy tools threat actors are using to get in.

Mark walks us through Proofpoint’s latest research on custom malware (yes, “Voldemort” is back), threat clusters with pun-filled names like UNK_SparkyCarp and UNK_DropPitch, and why Taiwan’s chip industry has become such a hot target. From design and manufacturing to financial analysts and supply chains, Chinese state-aligned actors are getting more creative—and more persistent.

We also unpack:

•  The “Phish & Chips” campaign and how it fits into China’s broader geopolitical strategy
  
  
  
•  Why pop culture references like Voldemort and Mr. Robot keep showing up in espionage infrastructure
  
  
  
• Attribution headaches, including Proofpoint’s tracking of multiple unattributed threat clusters with UNK designators
  
  
  
•  How AI, LLMs, and adversary-in-the-middle phishing are influencing espionage tactics
  
  
  
•  The use of RMM tools and spoofed MacOS folders for stealth
  
  
  
•  Why basic backdoors are making a strategic comeback
  
  
  
•  A threat intel team’s deep love for vegetables, puns, and report titles
  
  
  

Whether you're tracking state-sponsored cyber activity, curious about weird malware names, or just here for the expert banter, this episode has you covered.

Hello to all our Cyber Masked Vigilantes!  In this episode of Discarded, host Selena Larson and co-host Tim Kromhardt are joined by James Emery-Callcott, a Security Researcher on Proofpoint’s Emerging Threats team, for an insider’s look at the technical, tactical, and collaborative forces shaping modern network detection.

James takes us behind the curtain of rule writing, CVE coverage, and malware detection, breaking down how signatures are developed, validated, and deployed to protect against a constantly shifting threat landscape. From the fading heyday of exploit kits to the rise of infostealers and ClickFix, we explore how detections evolve—and why the most persistent threats often hinge on the fundamentals of networking.

You’ll also hear how the team maps detection rules to frameworks like MITRE ATT&CK and CISA KEV, using metadata tags to reduce alert fatigue and prioritize real-world risks. James shares why this kind of tagging isn’t just technical polish—it’s operational gold.

But detection doesn’t happen in a vacuum. James explains how the community—through Discord chats, support tickets, and collaborative research—plays a vital role in surfacing false positives, sharing POCs, and suggesting metadata improvements. 

Bonus highlights include:

• Why writing reliable detection rules is still too nuanced for AI
  
  
  
• The anatomy of a CVE rollout (and the surprising role of an Xbox controller)
  
  
  
• Signature performance testing and hardware challenges
  
  
  
• Why older vulnerabilities still matter
  
  
  
• A sneak peek at a free Suricata training series in the works
  
  
  

Whether it’s a shoutout to Tony for pushing tagging innovation or a nod to students eager to get started, the message is clear: everyone can contribute to better detection.

Hello to all our Cyber Spring Chickens! Join host Selena Larson, and guest host, Sarah Sabotka, as they chat with Saher Naumaan, Senior Threat Researcher at Proofpoint, for a deep dive into how modern espionage and cybercrime are increasingly blurring lines.

At the center of the conversation is ClickFix—a fast-evolving social engineering technique originally used by cybercriminals but now adopted by espionage actors across at least three countries in just 90 days. 

We explore: 

• how threat actors are borrowing each other’s tactics, techniques, and procedures (TTPs), creating “muddled attribution” as espionage groups mimic high-volume e-crime methods
• how these techniques are being tailored to target high-value, often non-technical individuals
• what defenders can do in the face of increasingly sophisticated psychological attacks

Hello to all our Cyber Spring Chickens! Join host Selena Larson and guest hosts, Tim Kromphardt and Sarah Sabotka, both Senior Threat Researchers at Proofpoint. 

These top sleuths crack open Proofpoint’s new Human Factor series and explore one of the most deceptively dangerous tactics in a threat actor’s playbook: the benign conversation.

What exactly is a benign conversation—and why is it anything but harmless? Whether it’s a simple “Do you have a minute?” or a seemingly legit job offer, these messages are often the opening moves in complex social engineering attacks used for fraud, malware delivery, and even nation-state espionage.

The team dives into:

• The top five fraud-related benign conversation themes, including the rise of advanced fee fraud
  
  
  
• Real-world examples of job scams, gift card requests, and a Taylor Swift-themed lure
  
  
  
• The difference between financially motivated lures and espionage-style social engineering
  
  
  
• How Iranian and North Korean threat actors are perfecting the art of trust-building through impersonation and tailored messages
  
  
  
• TOAD scams (Telephone-Oriented Attack Delivery) and the power of fear and urgency
  
  
  
• The critical role of spoofing in making these attacks believable
  
  
  
• The human toll and psychological manipulation behind scams like pig butchering—and why acknowledging the abuse behind them matters
  
  
  

From hijacked contact forms and fake antivirus invoices to AI-generated phone calls and scam compounds, this episode blends serious security insight with Friday vibes and candid discussion. 

Whether you're a seasoned threat analyst or just here for the “lure-palooza,” you’ll walk away with a sharper eye for red flags—and a deeper understanding of the evolving cyber threat landscape.
