AlienVault OTX Malware

The 'VBS Downloader and Defender Control' malware is a malicious threat primarily characterized by its use of Visual Basic Script (VBS) to download additional payloads and manipulate Windows Defender settings. This malware operates through batch scripts that execute VBS code to facilitate payload delivery and potentially disable or control Windows Defender, the built-in antivirus and anti-malware solution on Windows systems. The malware's core functionality involves network activity to fetch external malicious components, enabling further compromise or persistence on the infected system. Although specific affected versions or products are not detailed, the malware targets Windows environments where scripting and Defender controls are accessible. The malware is categorized under network activity, payload delivery, and external analysis, indicating its role in initial infection stages and evasion of security mechanisms. Despite being labeled with a low severity by the source, the malware's ability to disable or control Defender could significantly increase the risk of subsequent infections or unauthorized activities. No known exploits in the wild have been reported, suggesting limited or targeted use. A patch or mitigation guidance is available via Wilbur Security, emphasizing the importance of applying recommended security measures to prevent exploitation. The technical details indicate a moderate threat level (3) and analysis score (2), reflecting a relatively low but non-negligible risk. The malware's reliance on scripting and Defender manipulation makes it a concern primarily for Windows-based systems that do not have strict script execution policies or updated security configurations.

VBS Downloader and Defender Control

The threat described as "VBS Downloader and Defender Control" involves the use of Visual Basic Script (VBS) to download malicious payloads and potentially manipulate or disable Windows Defender, the native antivirus and anti-malware solution in Windows operating systems. VBS downloaders are scripts that automate the retrieval and execution of additional malicious components from remote servers, often used as initial infection vectors in multi-stage attacks. The mention of "Defender Control" suggests that the script may attempt to disable or circumvent Windows Defender protections, thereby increasing the likelihood of successful payload execution and persistence on the target system. Although the specific technical details are limited, the use of batch scripts and VBS downloaders is a common tactic employed by attackers to evade detection and facilitate the deployment of malware such as ransomware, trojans, or spyware. The threat level is indicated as moderate (3 out of an unspecified scale), with a low overall severity rating and no known exploits in the wild as of the published date (January 2020). The lack of affected versions and patch links implies this is more a tactic or malware family rather than a vulnerability in a specific product. The threat is categorized under malicious batch scripts and VBS downloaders, which are often used in phishing campaigns or drive-by downloads to compromise endpoints.
