Host: Steve Prentiss | Release Date: March 28, 2025

1. JavaScript Injection Campaign Compromises 150,000 Sites

Timestamp: [00:00]

Steve Prentiss opens the episode by highlighting a significant security threat uncovered by researchers at Website Security Company, known as Cside (spelled lowercase c forward slash side). This malicious campaign has successfully compromised approximately 150,000 websites through JavaScript injection.

Key Details:

• Methodology: The attack employs an iFrame injection technique to overlay malicious content via CSS, directing visitors to fraudulent Chinese gambling platforms.
• Targeted Platforms: Primarily affects infected WordPress sites, showcasing the adaptability and evolving sophistication of threat actors.

Prentiss emphasizes:
“This campaign infiltrates legitimate websites with malicious JavaScript using an iFrame injection to display a full-screen overlay...” [00:00]

2. Vulnerabilities in Solar Power Systems Pose Risks to Electrical Grids

Researchers from Forescout have identified multiple vulnerabilities within solar power system products from manufacturers such as Sungrow, Growwatt, I.E. G, R.O.W.a.T.T, and SMA.

Key Concerns:

• Affected Components:
  • Internet connectivity interfaces.
  • Cloud services handling monitoring and control data.
  • Mobile applications interfacing with cloud services.
• Potential Exploits:
  • Arbitrary Code Execution: Attackers could upload malicious files to cloud servers.
  • Data Theft & Vandalism: Unauthorized access to sensitive information or disruption of power grid operations.

Prentiss notes the severity of these vulnerabilities, stating that some could "pose a serious threat to electrical grids" if exploited.

3. T-Mobile Faces $33 Million Arbitration Over SIM Swap Attack

In a significant legal development, the law firm Greenberg Glusker secured a $33 million arbitration award against T-Mobile related to a SIM swap attack that resulted in a massive cryptocurrency theft.

Case Highlights:

• Incident Date: February 21, 2020.
• Losses Incurred: Bitcoin valued at $38 million was stolen after the attack.
• Legal Argument: The firm contended that T-Mobile's security lapses, potentially involving a system backdoor, facilitated the breach. Additionally, T-Mobile allegedly attempted to conceal details of its security failures.

Prentiss summarizes the outcome, emphasizing the court's stance on T-Mobile's responsibility in the security breach.

4. NHS Software Supplier Receives Discount on Fine After Ransomware Attack

Following the August 2022 Lockbit ransomware attack on Advanced Health and Care Ltd., a key IT service provider for the UK's National Health Service (NHS), the company has settled for a reduced fine.

Case Details:

• Original Fine Proposed: £6 million.
• Final Fine: Just over £3 million, half of the initial proposal.
• Settlement Reasons:
  • The company acknowledged the watchdog's decision without appealing.
  • Demonstrated cooperation with the NHS and regulatory bodies post-attack.
  • Implemented mitigation measures to address related risks.

Prentiss highlights the importance of compliance and proactive risk management in mitigating fines and penalties.

5. Kubernetes Vulnerabilities Put 40% of Cloud Environments at Risk

According to researchers at Wiz, defects in a Kubernetes component have exposed 40% of cloud environments to potential threats.

Vulnerability Insights:

• Affected Component: Ingress NGINX controller for Kubernetes (spelled NGINX).
• Number of Vulnerabilities: Five recently discovered, including one critical flaw with a CVSS score of 9.8.
• Current Exploitation: No active exploitation reported yet, but the risk remains extremely high for publicly exposed and unpatched controllers.

Expert Commentary:
Steven Fuhr, Principal Security Researcher at Rapid7, warns:
“With exploit code for this vulnerability starting to be published online, Kubernetes administrators should remediate publicly exposed instances on an urgent basis.”

Successful exploitation could lead to unauthorized access to cluster-wide secrets, including passwords and tokens, or even complete cluster takeover.

6. Top Microsoft Office Exploits to Watch For

The Hacker News team identifies the top three Microsoft Office exploits currently prevalent:

1. Phishing with Enhanced Email Attachments:

   • Incorporates fake CAPTCHA, Cloudflare challenges, and QR codes to deceive users.

2. Microsoft Equation Editor Zero-Click Exploit:

   • Despite being outdated, many systems still retain the Equation Editor, which allows remote code execution embedded within Word files without any user interaction.

3. Follina (0-Click) Exploit:

   • Leverages the Microsoft Support Diagnostic Tool and specially crafted URLs within Office documents to execute remote code silently.

Prentiss advises listeners to consult the Hacker News article linked in the show notes for detailed mitigation strategies.

7. Windows Server 2025 Updates Cause Remote Desktop Freezes

Microsoft has reported a known issue affecting Windows Server 2025 post-security updates released since February's Patch Tuesday.

Issue Description:

• Symptoms: Unresponsive mouse and keyboard inputs shortly after establishing a remote desktop connection, necessitating reconnection.
• Affected Versions: Also impacted Windows 1124H2, though this was resolved with the February 25th update.
• Current Status: Microsoft has yet to release a fix for Windows Server 2025 but plans to address it in future updates.

Prentiss underscores the inconvenience caused to administrators relying on remote desktop functionalities.

8. Mozilla Patches Critical Firefox Sandbox Escape Vulnerability on Windows

Mozilla has released Firefox version 1336.04 to address a critical security flaw that allows attackers to escape the browser's sandbox on Windows systems.

Vulnerability Details:

• Affected Releases: Both standard and extended support versions.
• Nature of the Flaw: Similar to a recent Chrome Zero-day, enabling attackers to confuse processes and leak handles, facilitating sandbox escapes.
• Exploitation Status: Mozilla confirmed that attackers have exploited a related vulnerability in the wild.
• Scope: Only affects Windows users; other operating systems remain unaffected.

Prentiss advises all Firefox users to update to the latest version immediately to safeguard against potential exploits.
