Cybersecurity Alert: Chinese State-Sponsored Attacks, DeskSoft RDP Exploits, and Elastic/Dynatrace Vendor Breach – September 9, 2025

September 9, 2025 – Today’s cybersecurity landscape is dominated by a confluence of significant threats, primarily centered around sophisticated state-sponsored attacks, a novel malware campaign leveraging a popular RDP application, and a data breach stemming from a third-party vendor impacting major data analytics platforms. These developments, confirmed by U.S. federal agencies and cybersecurity industry bodies, underscore the escalating complexity and urgency of defending critical infrastructure and enterprise networks.

1. U.S. Intelligence Warns of Sustained Chinese State-Sponsored Cyber Espionage

The U.S. House Select Committee on China released a formal assessment today detailing an ongoing, highly sophisticated cyber-espionage campaign orchestrated by Chinese state-sponsored Advanced Persistent Threat (APT) actors. The committee’s findings, based on intelligence gathered by the FBI and shared with global cybersecurity bodies, indicate a sustained and targeted effort aimed at gathering intelligence related to critical infrastructure and trade policy stakeholders.

According to the report, the attackers are utilizing developer tools to establish hidden access pathways within targeted networks. This tactic, described as a particularly concerning evolution in APT techniques, allows for prolonged, undetected access. The primary objective of this campaign appears to be the exfiltration of sensitive data, which is then transmitted to servers controlled by the Chinese actors.

“This is not a new tactic, but the level of sophistication and persistence demonstrated by these actors is deeply troubling,” stated a representative from the FBI, speaking on background. “The use of developer tools to create these hidden pathways represents a significant escalation and requires a fundamental shift in our defensive strategies.”

Following the committee’s announcement, global cybersecurity organizations, including the International Cyber Threat Alliance (ICTA), issued a joint advisory urging defenders to proactively hunt for malicious activity. The advisory recommends implementing a layered defense strategy, focusing on:

• Threat Hunting: Conducting thorough investigations to identify and neutralize hidden access pathways.
• Vulnerability Management: Regularly scanning for and patching vulnerabilities, particularly those related to developer tools and build processes.
• Network Segmentation: Isolating critical infrastructure networks to limit the potential impact of a successful intrusion.
• Endpoint Detection and Response (EDR): Deploying EDR solutions to monitor endpoint activity and detect anomalous behavior.
• Application Whitelisting: Implementing application whitelisting to restrict the execution of unauthorized software.

2. DeskSoft EarthTime RDP Trojan Campaign – A New Threat Emerges

A new malware campaign is exploiting vulnerabilities within DeskSoft’s EarthTime application to deploy malicious software via compromised Remote Desktop Protocol (RDP) connections. This campaign, which security researchers are currently tracking under the designation “Operation Driftwood,” leverages a trojanized version of EarthTime to gain initial access to targeted systems.

Initial analysis reveals that attackers are archiving sensitive data and exfiltrating it using unencrypted File Transfer Protocol (FTP). This reliance on unencrypted FTP represents a significant security weakness and a key indicator of the attackers’ intent. Crucially, the campaign is accompanied by evidence of reconnaissance activity, with links identified between the operation and known ransomware groups. This suggests a potential staging ground for future extortion attempts.

Security experts are recommending a series of mitigation steps:

• Application Whitelisting: Strictly limiting the execution of applications, particularly EarthTime and any related components.
• RDP Security Hardening: Implementing multi-factor authentication (MFA) for all RDP connections.
• Network Segmentation: Isolating systems running EarthTime to prevent lateral movement.
• Defender Policy Monitoring: Closely monitoring for any changes to Defender policies that could be exploited.
• Living-Off-the-Land Detection: Increased vigilance regarding the usage of tools like MSBuild.exe and rundll32.exe, as these are being utilized by the attackers to evade detection.

3. Elastic and Dynatrace Data Breaches Linked to Salesloft Drift

Elastic and Dynatrace today disclosed data breaches resulting from vulnerabilities exploited through a third-party vendor, Salesloft Drift. The breaches involved unauthorized access to sensitive data stored within the platforms. While the full scope of the compromise is still being determined, preliminary investigations indicate that attackers were able to gain access through vulnerabilities within Salesloft Drift’s software.

The compromised data includes customer usage data, configuration settings, and potentially, access credentials. Elastic and Dynatrace are working with law enforcement and cybersecurity firms to contain the breach and investigate the full extent of the damage. Both companies have issued statements urging customers to review their security practices and implement enhanced monitoring and alerting.

“We are taking this incident extremely seriously and are committed to providing our customers with the resources they need to protect their data,” stated a spokesperson for Dynatrace. “We are working closely with law enforcement and security experts to fully understand the scope of the breach and to implement measures to prevent future incidents.”

Summary of Developments (September 9, 2025)

Today’s cybersecurity landscape is characterized by a multi-faceted threat environment. The U.S. House Select Committee on China confirmed a sustained state-sponsored cyber espionage campaign targeting critical infrastructure and trade stakeholders, while a novel RDP-based malware campaign leveraging DeskSoft EarthTime emerged. Furthermore, a data breach impacting Elastic and Dynatrace was traced back to vulnerabilities exploited through a third-party vendor, Salesloft Drift. These developments underscore the ongoing need for robust cybersecurity defenses and proactive threat hunting across all sectors. The cumulative impact of these events highlights the increasing sophistication of cyberattacks and the critical importance of vigilance in maintaining data security.
