Release Date: January 16, 2025
Description: Deception, influence, and social engineering in the world of cybercrime.

Introduction

In the latest episode of Hacking Humans, hosted by Dave Buettner, Joe Kerrigan, and Maria Varmazes from N2K Networks, the trio delves deep into sophisticated cyber scams that blend social engineering with cutting-edge technology. The episode titled "Crypto Chameleons and Star Fraud" explores intricate fraud schemes involving cryptocurrencies and high-profile targets, shedding light on the evolving tactics of cybercriminals.

Story 1: Jury Duty Scammers in Florida

Timestamp: [01:33]

Joe Kerrigan opens the episode with a cautionary tale about Anthony Sanders and Marlita Andrews, who orchestrated a $12,000 scam targeting a woman in Sarasota, Florida. The scam involved pretending to be from the sheriff's office to claim the victim owed money for missed jury duty—a tactic highlighted by Joe:

Joe Kerrigan [01:50]: “Anthony Sanders called her and said, you owe money for missing jury duty. But, if you miss jury duty, they're not going to call you and demand money.”

Key Points:

• Anthony Sanders, operating from prison, and Marlita Andrews, his collaborator on the outside, executed the scam.
• They spoofed the sheriff's office phone number and convinced the victim to transfer $12,000 to a cryptocurrency wallet.
• The rapid dispersion of funds suggests the victim is unlikely to recover her money.
• The operation underscores the challenges of controlling scams that originate within prison systems.

Discussion Highlights:

• Maria Varmazes [02:22]: “It's not, at least in the United States. That is true, right?”
• The hosts discuss the ingenuity and boldness of conducting such operations from within prison, emphasizing the need for robust security measures.

Story 2: Phishing in Job Interviews

Timestamp: [05:24]

The second story involves a deceptive job interview process targeting software developers, as recounted by Franco Aguilera. Franco shared his experience where a seemingly legitimate job interview led him to download a malicious GitHub repository containing a script designed to steal cryptocurrency keys.

Notable Quote:

Joe Kerrigan [06:06]: “What happened with this guy is they said, I need you to go out and download this client-server package and fire up the server, and then we're going to try to interact with it... this script was going out and collecting information and sending it to an IP on the Internet somewhere.”

Key Points:

• Phishing Tactics: Using fake job interviews to lure victims into running malicious software.
• Malicious Code: The downloaded repository contained obfuscated code that compromised Franco’s system.
• Preventative Measures: Emphasis on conducting code reviews and using virtual machines (VMs) to isolate such exercises.

Discussion Highlights:

• Dave Buettner [06:19]: “Can you explain what code challenges are for somebody seeking this kind of employment?”
• Maria Varmazes [08:32]: “Right. Like, we should never expect this to be happening.”
• The hosts stress the importance of skepticism during unsolicited technical requests and the benefits of using VMs to mitigate potential risks.

Story 3: Voice Phishing Operations

Timestamp: [12:43]

Drawing from an investigative report by Brian Krebs on Krebs on Security, the hosts explore the operations of a sophisticated voice phishing crew named Crypto Chameleon. This group offers phishing kits as a service, catering to various aspects of the scam operation.

Notable Quotes:

Dave Buettner [13:12]: “One specific thing in the pile of it is actually something you need to address right now. So all of that sounds like technology maybe making life better, but I think you can probably anticipate where this is going.”

Joe Kerrigan [17:10]: “They rent out their fishing kits. Very businesslike.”

Key Points:

• Crypto Chameleon: A cybercriminal group providing turnkey phishing solutions.
• Operational Structure:
  • Callers: Engage victims through impersonated support services (e.g., Google, Apple).
  • Operators: Manage the phishing tools and infrastructure.
  • Drainsters: Execute the financial theft by accessing victims' cryptocurrency wallets.
• Phishing Process:
  1. Target Identification: Using tools like "autodoxers" to sift through data breaches and identify high-value targets.
  2. Initial Contact: Deploying phishing emails, calls, or notifications masquerading as legitimate entities.
  3. Building Trust: Imitating support agents to guide victims into divulging sensitive information.
  4. Credential Theft: Directing victims to fake login pages to capture usernames, passwords, and two-factor authentication codes.
  5. Financial Drain: Extracting funds from compromised accounts, particularly cryptocurrency wallets.

Discussion Highlights:

• Maria Varmazes [20:57]: “It's just always amazing to me how sophisticated these operations are.”
• The hosts emphasize the alarming professionalism of such operations, likening them to a "crew from Ocean's Eleven," highlighting the need for enhanced vigilance and security protocols.

Preventative Measures:

• Awareness: Recognizing unsolicited communications claiming to be from trusted entities.
• Verification: Always verifying the authenticity of support requests through official channels.
• Security Practices: Implementing strong, unique passwords and enabling robust two-factor authentication.

Apple’s AI-Generated Notification Summaries: A Double-Edged Sword

Timestamp: [23:55]

Maria Varmazes introduces a discussion on Apple's latest iOS feature—AI-generated summaries of app notifications. While designed to declutter user experiences, the feature has inadvertently facilitated scamming tactics.

Notable Quotes:

Maria Varmazes [24:26]: “But they are having some kind of fare sale. I'm not going anywhere. I don't need to know that.”

Maria Varmazes [25:36]: “There are also some fun versions of these summaries going out... AI can help you with that. It's so great.”

Key Points:

• Functionality: Apple’s AI condenses multiple app notifications into concise summaries, aiming to streamline user interactions.
• Security Concerns: Cybercriminals exploit these summaries to highlight misleading priorities, making scam messages appear urgent and legitimate without the usual contextual warnings.
• Examples of Misrepresentation:
  • Fake Security Alerts: AI-generated messages urging immediate action on supposed security issues.
  • False Delivery Notifications: Prompts to verify personal details to release fake packages.

Discussion Highlights:

• Dave Buettner [22:10]: “Apple and Google both warn and reiterate that they will never ask you for your password or call you unsolicited.”
• Maria Varmazes [28:43]: “AI is now sanitizing all of those cues that we have learned to look for... this is priority.”

Recommendations:

• Disable the Feature: Until the AI can accurately distinguish and flag potential scams.
• User Vigilance: Continually verify the authenticity of notifications through official apps or websites.

Catch of the Day: Voicemail Scam Analysis

Timestamp: [34:47]

The hosts present a recurring scam voicemail example received by a listener named Keefe. The message impersonates Walmart, informing the recipient of a pre-authorized purchase to lure them into engaging with the scam.

Voicemail Transcript:

“Hey, this is Amelia from Walmart. A pre authorized purchase of PlayStation 5 with special edition and Pulse 3D headset is being ordered from your Walmart account for an amount of $919.45. To cancel your order or to connect with one of our customer support representatives, please press 1.”

Notable Quote:

Dave Buettner [36:01]: “If you didn't make this purchase, do not engage. Check your account directly through Walmart's official website or app.”

Debunking the Scam with AI: Dave demonstrates utilizing ChatGPT to summarize and analyze the voicemail, effectively identifying it as a potential phishing attempt.

Conclusion and Takeaways

The episode underscores the escalating sophistication of cyber scams, emphasizing the intricate blend of social engineering, technological manipulation, and organized criminal operations. The hosts advocate for heightened awareness, robust security practices, and skepticism towards unsolicited communications to safeguard against such threats.

Final Thoughts:

• Maria Varmazes [21:56]: “It's really remarkable how my old mental model of this being just some lone troublemaker... is so, so outdated.”
• Joe Kerrigan [22:10]: “Never trust the inbound call and never give those codes out. Those codes are for you and you alone.”
