The threat involves the exposure of the internal parsed data of the VB6 disassembler vbdec through a live COM interface registered in the Windows Running Object Table (ROT). This interface allows any local process to access and script the disassembler's internal object model, including forms, classes, modules, and P-code bodies. Cisco Talos demonstrates how local AI agents can leverage this interface to automate complex reverse engineering tasks such as source reconstruction, call graph generation, and opcode database creation. The approach does not require modifying vbdec or uploading binaries externally, preserving local data confidentiality. While this technique is presented as a capability for analysts, it also represents a potential local attack surface if an adversary gains local access and can script the COM objects to extract sensitive information or automate analysis.

The impact is limited to local environments where an attacker or user has access to the machine running vbdec with remote scripting enabled. The exposure of the live COM object model could allow unauthorized local processes to query and manipulate the disassembler's internal data, potentially leaking sensitive reverse engineering information or enabling automation of analysis without user consent. There is no indication of remote exploitation or widespread active exploitation in the wild. The threat is primarily a local security consideration related to the exposure of internal application data through COM interfaces.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. In the meantime, users should consider disabling remote scripting in vbdec if not required (Help → Options → Disable Remote Scripting) to prevent exposure of the live COM object model. Restrict local access to trusted users and processes to reduce risk. Monitor vendor advisories for any official fixes or guidance regarding secure configuration of vbdec's COM interface. Since this is a local exposure, standard endpoint security controls limiting unauthorized local code execution will help mitigate risk.
