Overview: A novel attack vector, termed "repo swatting," is emerging, targeting repositories on GitHub and GitLab to illegitimately force their removal.

Key Points:

• Attackers exploit hidden features to upload malicious files within repository issues without publication.
• By reporting these concealed threats, they compel platform administrators to delete the repositories under false pretenses.
• This method undermines the integrity of issue reporting and poses significant risks to developers relying on these platforms.

Notable Quote: Steve Gibson laments, “This is what's keeping Uber from having nice things” (60:02), highlighting the frustration with such malicious tactics.

6. Palo Alto Networks Suffers Critical Zero-Day Vulnerabilities

Overview: The episode addresses severe zero-day vulnerabilities discovered in Palo Alto Networks' enterprise firewalls, exposing customers to potential breaches.

Key Points:

• Vulnerabilities stem from poor implementation using PHP, making the systems susceptible to remote code execution.
• An analysis by Watchtower Labs revealed flawed authentication layers, with internal comments condemning the hack.
• Over 2,000 Palo Alto Networks firewalls were compromised, allowing persistent attacker access through PHP webshells.

Notable Quote: Steve criticizes the design, stating, “They introduce its use by noting... this is their own source code. Their own PHP code contains the comment 'these are horrible hacks'” (65:04).

7. D-Link VPN Routers: Terminal Vulnerabilities and End-of-Life Risks

Overview: Six older models of D-Link VPN routers are highlighted for possessing stack buffer overflow vulnerabilities, leaving them exposed without forthcoming patches.

Key Points:

• The vulnerabilities allow unauthenticated remote code execution, posing dire risks to networks relying on these devices.
• All affected routers have surpassed their end-of-life, meaning no future updates or fixes will be provided.
