Release Date: January 6, 2025

Introduction

In the January 6, 2024 episode of Cybersecurity Today, host Jim Love delves into pressing cybersecurity issues impacting businesses and governmental institutions. The episode covers significant browser exploits, a major breach at the U.S. Department of the Treasury, and CrowdStrike’s remarkable recovery from an unprecedented IT outage. Love offers insightful analysis, expert opinions, and actionable advice for securing organizations in a perilously digital landscape.

1. Browser Exploits: Double Clickjack and Compromised Extensions

a. Compromised Browser Extensions

Jim Love opens the discussion by highlighting severe vulnerabilities in commonly used browsers, particularly focusing on Google Chrome. He remarks:

"If you use Google Chrome or any browser really, you might want to think twice before you double click." – [00:00]

Key Points:

• Discovery of Compromised Extensions: During the holiday season, Cyberhaven's security researchers unearthed a compromise in their Chrome extension. This extension, designed to bolster security by preventing users from entering sensitive information, was exploited due to a vulnerability in Chrome's developer authentication system.

• Scope of the Breach: Cyberhaven was not alone; at least 33 popular browser extensions were infected, affecting approximately 2.6 million devices. The attackers executed a spear-phishing campaign targeting extension developers, stealing credentials to upload malicious versions seamlessly. Consequently, users were unknowingly exposed as the malicious updates installed automatically upon opening Chrome.

• Expert Insight: John Tuckner, founder of Secure Annex, explains the sophistication of the attack:

  "The attackers relied on custom lookalike domains... likely compromising at least 19 other extensions, leading to a total of 1.46 million suspicious downloads." – [00:05]

b. Double Clickjacking Exploit

The conversation shifts to a novel double clickjacking exploit uncovered by security researcher Paulo Zabello. Unlike traditional clickjacking, which relies on invisible iframes blocked by modern browsers, this new method operates across multiple browsers, including Chrome, Edge, and Safari.

Key Points:

• Mechanism of Attack: By timing two clicks in rapid succession, attackers can insert malicious authorizations without user awareness. This tactic can trick users into granting unintended permissions or altering security settings instantaneously.

• Implications for Browser Security: These developments underscore a significant challenge for browser security, where trusted extensions and seemingly benign user actions like double-clicking can be exploited creatively by attackers.

• Jim Love's Commentary:

  "The double clickjack effectively reopens a clickjacking threat surface that many believed was dead." – [00:10]

c. Expert Recommendations

In response to these threats, cybersecurity experts advocate for enhanced browser extension controls. Suggestions include implementing asset management lists that restrict extensions to pre-approved add-ons and increasing user awareness regarding suspicious double-click actions.

"Organizations should consider stricter browser extension controls... be cautious with double click actions, especially if a prompt seems unusual or appears to come out of nowhere." – [00:15]

2. U.S. Treasury Breach: A State-Sponsored Attack

a. Details of the Breach

The episode transitions to a significant cybersecurity incident involving the U.S. Department of the Treasury. Attackers gained unauthorized access to Treasury workstations, leading to the theft of unclassified documents.

Key Points:

• Method of Attack: On December 8, Beyond Trust, a third-party service provider, alerted the Treasury to the breach. Attackers had obtained a remote support key, enabling them to bypass standard security protocols and exfiltrate data undetected until post-breach detection.

• Attribution: Treasury officials have attributed the attack to a Chinese state-sponsored advanced persistent threat (APT) group, marking a continuation of supply chain breaches targeting U.S. government entities.

"Treasury labeled the incident major and attributed it to a Chinese state-sponsored advanced persistent threat or APT actor." – [00:20]

b. Implications and Response

Although the stolen data was unclassified, the breach raises concerns about intelligence gathering, future operation groundwork, and the robustness of government cybersecurity defenses.

Expert Insights:

• Risks of Third-Party Software: The incident highlights the vulnerabilities inherent in third-party service providers within the federal tech infrastructure. A single compromised vendor can offer a gateway to sensitive governmental systems.

• Government Response: The Treasury has taken affected services offline, while the Cybersecurity and Infrastructure Security Agency (CISA), FBI, and intelligence agencies collaborate with forensic experts to investigate the breach.

"The breach underscores the risks of third-party software in the federal tech stack." – [00:25]

c. Broader Context

This incident adds to a series of reported cyber infiltrations, including the compromise of U.S. telecommunications systems by Chinese hackers. The Wall Street Journal reported extensive breaches involving major telecom operators like AT&T, Verizon, Lumen, and T-Mobile, as well as exploitation of unpatched network devices from Fortinet and Cisco Systems.

"The big question: Are these breaches a rehearsal for something even more disruptive?" – [00:30]

3. CrowdStrike's Comeback: Recovering from the Largest IT Outage in History

a. Overview of the Incident

Jim Love discusses CrowdStrike’s recent turmoil caused by a catastrophic IT outage following a flawed software update.

Key Points:

• The Outage: In July, CrowdStrike deployed an update to its flagship Falcon security software. This update led to the crashing of millions of Windows PCs and servers globally, disrupting critical services across various industries, including airlines, healthcare, and broadcasting.

"It was so massive that U.S. House Homeland Security Committee Chair Mark Green dubbed it the largest IT outage in history." – [00:35]

• Impact on Clients: The outage caused significant operational disruptions, with Delta Airlines alone reporting losses exceeding $500 million and initiating a lawsuit against CrowdStrike.

b. CrowdStrike’s Response and Recovery

Despite the severity of the outage, CrowdStrike has demonstrated resilience and transparency in its recovery efforts.

Key Points:

• Transparency and Accountability: CEO George Kurtz maintained that customer trust remained intact, asserting:

  "Customers are staying with us and reported one client, comparing this to the experience of a broken bone that heals stronger." – [00:40]

• Market Recovery: Remarkably, CrowdStrike has reclaimed over $30 billion in market value lost during the outage. The company reported a 29% increase in quarterly revenue, reaching approximately $1 billion, and retained 97% of its customers.

• Legal and Operational Challenges: While CrowdStrike faces legal battles, their lawyers argue contractual limitations on liability, mitigating the scale of Delta’s claims.

"CrowdStrike went for total honesty... no doubt that after the initial stumbles, there were a ton of lawyers who were freaking out." – [00:45]

c. Industry Analysis and Future Outlook

Analysts believe that CrowdStrike's essential role in enterprise security and their adept handling of the crisis have prevented a mass customer exodus. Additionally, discussions have emerged regarding the level of access third-party security tools should have to operating systems, with some attributing the extent of the damage to vulnerabilities in Microsoft’s Windows OS.

"There's a question about whether it can keep this momentum going... how fragile our interconnected systems are and how dependent we are on them." – [00:50]

CrowdStrike’s upcoming evaluations in the fourth quarter, coupled with customer renewal cycles and commitment packages, will be critical in determining the company’s sustained recovery and market position.

Conclusion

Jim Love wraps up the episode by reflecting on the intricate vulnerabilities within our digital infrastructure. The discussions emphasize the need for heightened security measures, vigilant third-party management, and robust incident response strategies to navigate the evolving threat landscape effectively.

"Maybe even more important, once we take the focus off CrowdStrike and what was surely a stupid error, we need to think about how fragile our interconnected systems are and how dependent we are on them." – [00:55]
