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.

APT43: North Korean Group Uses Cybercrime to Fund Espionage Operations

APT43, also known as Kimsuky, is a North Korean advanced persistent threat (APT) group that has been observed leveraging cybercrime activities to fund its espionage operations. This threat actor employs a sophisticated and multi-faceted attack methodology primarily centered around social engineering techniques such as phishing and spearphishing (MITRE ATT&CK T1566, T1566.001, T1566.002). The group uses malicious links and attachments to gain initial access to targeted systems. Once inside, APT43 utilizes a wide range of tactics and techniques to maintain persistence, escalate privileges, and conduct reconnaissance. These include the use of scheduled tasks (T1053.005), Windows Management Instrumentation (T1047), command and scripting interpreters such as PowerShell and Windows command shell (T1059.001, T1059.003), and code injection methods (T1055 series). 

APT43 also compromises infrastructure by leveraging virtual private servers (T1583.003) and multi-hop proxies (T1090.003) to obfuscate command and control (C2) communications, which often use web protocols (T1071.001) and DNS tunneling (T1071.004). The group employs digital and code signing certificates (T1588.003, T1588.004) to sign malware and evade detection, and installs these certificates (T1608.003) to masquerade malicious payloads as legitimate software. They also use obfuscation techniques such as binary padding, software packing, and indicator removal (T1027 series) to avoid signature-based detection. 

APT43 conducts extensive discovery activities (T1007, T1010, T1012, T1016, T1033, T1057, T1082, T1083, T1087, T1518) to map out the environment and identify valuable targets. They capture sensitive data through keylogging (T1056.001), screen capture (T1113), clipboard data collection (T1115), and exfiltrate data via automated methods (T1020). The group also employs brute force attacks (T1110) and steals credentials from web browsers (T1555.003) to expand access. Persistence is maintained through registry run keys, startup folders, Windows services, and Winlogon helper DLLs (T1547 series, T1543.003). They also use advanced evasion techniques such as virtualization/sandbox evasion (T1497), debugger evasion (T1622), and reflective code loading (T1620). 

This threat actor is known to exploit client execution vulnerabilities (T1203) and uses malicious files and links (T1204.001, T1204.002) to deliver payloads. They manipulate system processes and tokens (T1134) and modify system registries (T1112) to maintain control. The group’s operations are perpetual and ongoing, with known exploits in the wild, and no patches are currently available for the vulnerabilities exploited. The threat level is high due to the combination of espionage objectives and cybercrime funding activities, making it a persistent and dangerous actor.
