New targets, new tools, same threat.
This week we are joined by Chester Wisniewski, Global Field CTO from Sophos X-Ops team, to discuss their work on "Crimson Palace returns: New Tools, Tactics, and Targets." Sophos X-Ops has observed a resurgence in cyberespionage activity, tracked as Operation Crimson Palace, targeting Southeast Asian government organizations. After a brief lull, Cluster Charlie resumed operations in September 2023, using new tactics such as web shells and open-source tools to bypass detection, re-establish access, and map target network infrastructure, demonstrating ongoing efforts to exfiltrate data and expand their foothold.
In this episode, Trevor Hilligoss, VP of SpyCloud Labs at SpyCloud, discusses the increasing threat of ransomware, emphasizing the role of infostealer malware in facilitating these attacks. He draws from SpyCloud's 2024 Malware and Ransomware Defense Report, highlighting how compromised identity data from infostealers creates opportunities for ransomware operators. With 75% of organizations experiencing multiple ransomware attacks in the past year, Trevor explores findings from over 500 security leaders in the US and UK, discussing the challenges businesses face and how they can use insights from this research to defend against ransomware and other cybercrimes.
Joshua Miller from Proofpoint is discussing their work on "Best Laid Plans: TA453 Targets Religious Figure with Fake Podcast Invite Delivering New BlackSmith Malware Toolset." Proofpoint identified Iranian threat actor TA453 targeting a prominent Jewish figure with a fake podcast interview invitation, using a benign email to build trust before sending a malicious link. The attack attempted to deliver new malware called BlackSmith, containing a PowerShell trojan dubbed AnvilEcho, designed for intelligence gathering and exfiltration. This malware consolidates all of TA453's known capabilities into a single script rather than the previously used modular approach.
We are joined by Yves Younan, Senior Manager, Talos Vulnerability Discovery and Research from Cisco, discussing their work on "How multiple vulnerabilities in Microsoft apps for macOS pave the way to stealing permissions." Cisco Talos has uncovered eight vulnerabilities in Microsoft applications for macOS that could allow attackers to exploit the system's permission model by injecting malicious libraries. By leveraging permissions already granted to these apps, attackers could gain access to sensitive resources like the microphone, camera, and screen recording without user consent. While Microsoft considers these issues low risk and has declined to fix them, the vulnerabilities pose a potential threat to user privacy and security.
Jonathan Tanner, Senior Security Researcher from Barracuda, discussing their work on "Stealthy phishing attack uses advanced infostealer for data exfiltration." The recent phishing attack, detailed by Barracuda, uses a sophisticated infostealer malware to exfiltrate a wide array of sensitive data. The attack begins with a phishing email containing an ISO file with an HTA payload, which downloads and executes obfuscated scripts to extract and transmit browser information, saved files, and credentials to remote servers. This advanced infostealer is notable for its extensive data collection capabilities and complex exfiltration methods, highlighting the increasing sophistication of cyber threats.
