AlienVault OTX Malware

The provided information describes a reconnaissance campaign involving an "Interesting Recon Script" identified by CIRCL under the kill-chain project. This campaign is characterized by the use of scripting techniques (MITRE ATT&CK T1064) executed via command-line interfaces (T1059) and requiring user execution (T1204). The script performs extensive discovery activities across multiple domains: account discovery (T1087), domain trust discovery (T1482), file and directory discovery (T1083), network share discovery (T1135), permission groups discovery (T1069), process discovery (T1057), registry queries (T1012), remote system discovery (T1018), software discovery (T1518), system information discovery (T1082), and system network connections discovery (T1049). These activities indicate a comprehensive reconnaissance phase aimed at gathering detailed information about the target environment, including user accounts, network topology, permissions, running processes, installed software, and system configurations. The campaign does not specify affected product versions, and no known exploits in the wild have been reported. The threat level is moderate (3), with a low severity rating assigned by the source. The attack requires user interaction to execute the script, which suggests it may be delivered via phishing or social engineering. The campaign's focus on discovery techniques aligns with early-stage intrusion activities, potentially preceding more impactful attacks such as lateral movement or data exfiltration.

Interesting Recon Script

SectorJ04 Groupâ€™s Increased Activity in 2019

The SectorJ04 threat group, also known as TA505, demonstrated increased activity in 2019 involving a broad range of sophisticated attack techniques primarily targeting Windows environments. This group employs spearphishing methods, including malicious attachments (T1193) and links (T1192), often leveraging trusted relationships (T1199) to gain initial access. Once inside a network, they utilize various execution techniques such as command-line interface (T1059), PowerShell (T1086), rundll32 (T1085), scheduled tasks (T1053), scripting (T1064), service execution (T1035), and execution through API or module loading (T1106, T1129). They also exploit client-side vulnerabilities (T1203) and user execution (T1204) to facilitate payload delivery.

For defense evasion, SectorJ04 uses methods like DLL side-loading (T1073), disabling security tools (T1089), bypassing User Account Control (T1088), code signing (T1116), obfuscation (T1027), software packing (T1045), virtualization/sandbox evasion (T1497), and hiding windows (T1143). Persistence is maintained through account manipulation (T1098), new services (T1050), registry run keys/startup folders (T1060), startup items (T1165), and WMI event subscriptions (T1084). They conduct extensive discovery activities including account (T1087), file and directory (T1083), network service scanning (T1046), network share (T1135), permission groups (T1069), process (T1057), registry queries (T1012), remote system (T1018), security software (T1063), system information (T1082), network configuration (T1016), network connections (T1049), system owner/user (T1033), and system service discovery (T1007).

For lateral movement and command and control, they use remote desktop protocol (T1076), remote services (T1021), custom and standard application layer protocols (T1094, T1071), and cryptographic protocols (T1024, T1032). Data collection techniques include automated collection (T1119), local system data (T1005), and email collection (T1114). Exfiltration is performed via automated exfiltration (T1020), alternative protocols (T1048), and command and control channels (T1041), often compressing (T1002) and encrypting data (T1486) to evade detection. This comprehensive attack lifecycle demonstrates SectorJ04's capability to conduct complex, multi-stage intrusions with a focus on stealth and persistence.

Although no specific affected software versions or exploits in the wild are documented, the group's tactics align with advanced persistent threat (APT) behavior targeting enterprise environments, particularly those with Windows infrastructure. The low severity rating likely reflects the absence of a single exploitable vulnerability but rather a combination of social engineering and post-compromise techniques.
