Date: August 25, 2025
Host: Steve Prentiss

Episode Overview

This episode spotlights major recent events in cybersecurity, including the discovery of a credential-stealing Go module, the resurgence of a Mirai-based botnet, and new cloud exploitation tactics by the Silk Typhoon group. It also covers a ransomware attack on electronics manufacturer Data IO, U.S. efforts to modernize federal cyber hiring, a significant breach in a women’s safety app, China's unusual nationwide internet blackout, and a regulatory warning to tech firms over foreign censorship compliance.

Key Discussion Points & Insights

1. Malicious Go Module Used for Credential Theft

[00:06–01:40]

• What happened: Researchers at Socket discovered a Go module posing as an SSH brute force tool, but actually exfiltrates credentials via Telegram.
• How it works:
  • Scans random IPv4 addresses for exposed SSH services on port 22.
  • Uses embedded username/password dictionaries for brute forcing.
  • Sends compromised credentials (IP, username, password) to a hard-coded Telegram bot.
• Details: The package, named golang_randomipssh_bruteforce, linked to a now-deleted GitHub account.
• Speaker Insight:

  "It does this by sending the target IP address, username and password to a hard coded Telegram bot controlled by the threat actor."

2. New Mirai-Based Botnet Resurfaces

[01:41–02:29]

• Discovery: FortiGuard Labs is tracking a Mirai variant using both N-Day and Zero-day exploits.
• Targets: A range of brands including Draytek, TP Link, Raisecom, Cisco, Neterbit, and Weimar smart home devices.
• Evasion & Aggression: The operators even launched DDoS attacks against the researchers tracking them.
• Quote:

  "It has been hitting four Faith brand industrial routers and as well Neterbit routers and Weimar smart home devices. Its operators have also been launching DDoS attacks against the researchers who are tracking it."

3. Silk Typhoon (Hafnium) Exploits Cloud Trust Relationships

[02:29–03:10]

• Technique: The group leverages the implicit trust given to cloud providers (who often have administrative access) to gain entry to customer environments.
• Impact: Able to access networks and data of downstream customers, maintaining stealthy access due to trusted status.
• Expert analysis:

  "By exploiting these trust models, Murky Panda can more easily blend in with legitimate traffic and activity to maintain stealthy access for long periods."
  — CrowdStrike via Steve Prentiss [03:04]

4. FTC Warns Tech Companies Against Foreign Censorship Compliance

[03:10–03:49]

• Context: FTC Chairperson Andrew Ferguson criticizes U.S. tech giants for complying with European and British data laws that could amount to censorship or weakened encryption.
• Legal threat: Such compliance might violate Section 5 of the FTC Act, which prohibits unfair or deceptive practices.
• Memorable Quote:

  "American consumers do not reasonably expect to be censored to appease a foreign power and may be deceived by such actions."
  — Steve Prentiss summarizing Ferguson [03:45]

5. Data IO Ransomware Attack

[03:51–04:31]

• Victim: Data IO, a component maker for clients like Tesla, Amazon, and Google.
• Attack Date: August 16, 2025.
• Impacts: Disrupted shipping, manufacturing, and production.
• Response: Third-party investigation underway before notifying potential breach victims.

6. U.S. Lawmakers Propose Cybersecurity Hiring Modernization Act

[04:33–05:16]

• Objective: Federal hiring to prioritize skills over formal educational degrees for cyber roles.
• Sponsors: Representatives Nancy Mace (R-SC) and Chantel Brown (D-OH).
• Rationale: Widen applicant pool and meet urgent security needs.
• Quote:

  "We need to make sure our federal agencies hire the most qualified candidates, not just those with traditional degrees."
  — Nancy Mace as quoted by Steve Prentiss [05:06]

7. Massive Data Breach in Women-Only Safety App

[05:19–06:30]

• App: Women Only Tea (dating/advice app)
• Breach specifics:
  • 72,000 images leaked (13,000 selfies, driver's licenses meant for deletion after verification)
  • Later, 1.1 million private direct messages uncovered from 2023–2025
• Outcomes:
  • Messaging feature suspended
  • Ten class action lawsuits filed
  • Calls for app store removal
  • Offers of identity theft and credit monitoring for affected users
• Expert Opinion: App's security called "weak" by cybersecurity experts.
• Notable Moment:

  "The crisis deepened… when a Researcher uncovered over 1.1 million private direct messages... revealing intimate conversations and personal identifiers."
  — Steve Prentiss [06:03]

8. Unprecedented Internet Blackout in China

[06:35–07:37]

• Event: China disconnected itself country-wide from the Internet for over an hour by blocking TCP port 443 (HTTPS).
• Impact: Affected all outbound web traffic, including services for Apple and Tesla.
• Motives Unclear: Could have been a test or an error, but highlights China’s ability to control the nation’s connectivity.
• Quote:

  "Not only did this prevent China's citizens from reaching websites hosted outside China, it also blocked other services that rely on Port 443, such as those used by Apple and Tesla..."
  — Steve Prentiss [06:56]
