CERT-FR report extended - sandworm intrusion set campaign targeting Centreon systems

The CERT-FR report details an ongoing cyber espionage campaign attributed to the Sandworm intrusion set, a threat actor group known for sophisticated and persistent attacks. This campaign specifically targets Centreon systems, which are widely used IT infrastructure monitoring solutions. The attackers exploit public-facing Centreon applications (MITRE ATT&CK T1190) to gain initial access, leveraging vulnerabilities or misconfigurations in these web-facing components. Once inside, the adversaries deploy server software components (T1505) and create or modify system processes (T1543) to establish persistence. They also schedule tasks or jobs (T1053) to maintain footholds and execute malicious payloads. The attackers use command and scripting interpreters (T1059) to execute arbitrary commands and abuse elevation control mechanisms (T1548) to escalate privileges. They perform file and directory discovery (T1083) to map the environment and deobfuscate or decode files (T1140) to analyze or prepare payloads. Communications with command and control (C2) servers are conducted over encrypted channels (T1573) using application layer protocols (T1071), enabling stealthy data exfiltration (T1041). The campaign is highly targeted, with a focus on French organizations, reflecting the strategic interest of the Sandworm group in this region. No patches are currently available for the exploited vulnerabilities, and no known exploits are publicly documented, indicating a potentially zero-day or custom exploit scenario. The campaign's sophistication and persistence suggest a high level of attacker capability and intent to maintain long-term access for espionage or sabotage purposes.

3CX Software Supply Chain Compromise Initiated by a Prior Software Supply Chain Compromise; Suspected North Korean Actor Responsible

The 3CX software supply chain compromise represents a sophisticated and multi-stage attack attributed to a suspected North Korean threat actor. This attack leverages a prior software supply chain compromise to infiltrate the 3CX software ecosystem, a widely used unified communications platform. The adversary employed advanced techniques including hijacking execution flow via DLL side-loading, process injection, and obfuscation to maintain persistence and evade detection. The attack chain involved the installation of fraudulent digital certificates to masquerade malicious payloads as legitimate software components, thereby bypassing security controls that rely on code signing verification. The threat actor also engaged in indicator removal tactics such as clearing Windows event logs and deleting files to hinder forensic investigations. Additionally, the attacker conducted extensive system reconnaissance activities including querying the registry, system information discovery, and environment profiling (system location and language discovery) to tailor their operations and avoid sandbox or debugger detection. Communication with command and control infrastructure was conducted over encrypted channels using application layer protocols, facilitating stealthy ingress tool transfers and data exfiltration. The malware families and tools associated with this compromise include PoolRat, IconicStealer, DaveShell, SigFlip, VeiledSignal, ColdCat, and TaxHaul, indicating a broad toolkit designed for espionage, credential theft, and lateral movement within compromised networks. Despite the absence of known exploits in the wild at the time of reporting, the complexity and depth of this supply chain attack pose a significant threat to organizations relying on the 3CX platform, especially given the supply chain vector which inherently undermines trust in software updates and distribution mechanisms.

Prynt Stealer Spotted In the Wild - A New Info Stealer Performing Clipper And Keylogger Activities

Prynt Stealer is a recently identified information-stealing malware campaign observed in the wild, primarily designed to perform clipper and keylogger activities. This malware targets user credentials and sensitive information by capturing keystrokes and manipulating clipboard data to intercept cryptocurrency wallet addresses or other copied sensitive data. The stealer leverages multiple MITRE ATT&CK techniques, including user execution (T1204), system and process discovery (T1497.001, T1057), account discovery (T1087), software discovery (T1518), and system service and location discovery (T1007, T1614). It also performs credential theft from password stores (T1555), steals web session cookies (T1539), and application access tokens (T1528), indicating a broad scope of data exfiltration. The malware captures screen content (T1113) and exfiltrates data over command and control (C2) channels and web services (T1041, T1567). Prynt Stealer’s infection vector relies on user execution, meaning it requires victims to run malicious files or scripts, often delivered via phishing or social engineering. Although no known exploits are currently reported in the wild, the malware’s capabilities to harvest credentials, session tokens, and clipboard data pose significant risks to confidentiality and integrity of user data. The campaign’s perpetual lifetime and moderate certainty level (50%) suggest ongoing monitoring is necessary. The absence of affected versions implies it targets general Windows environments rather than specific software vulnerabilities.

The CERT-FR report highlights an extended campaign by the Sandworm intrusion set targeting Centreon systems. Centreon is an IT infrastructure monitoring software widely used to oversee network, server, and application performance. The Sandworm group, known for its sophisticated cyber-espionage and sabotage operations, exploits public-facing Centreon applications to gain unauthorized access. The attack techniques align with MITRE ATT&CK patterns such as exploiting public-facing applications (T1190), leveraging server software components (T1505), and creating or modifying system processes (T1543) to establish persistence. The adversaries also use scheduled tasks or jobs (T1053) and command and scripting interpreters (T1059) to execute malicious payloads. They abuse elevation control mechanisms (T1548) to gain higher privileges and employ deobfuscation techniques (T1140) to evade detection. Post-compromise activities include file and directory discovery (T1083), establishing encrypted command and control channels (T1573), using application layer protocols for communication (T1071), and exfiltrating data over these channels (T1041). Although no specific affected versions or patches are listed, the campaign's high confidence and almost-certain likelihood suggest active targeting of Centreon deployments, particularly in France. The threat level is moderate (4), and no known exploits in the wild have been reported yet, indicating a potential for future exploitation if mitigations are not applied.
