Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
T1039 Data from Network Shared Drive Collection
Adversaries may search network shares on computers they have compromised to find files of interest.
T1119 Automated Collection Collection
Once established within a system or network, an adversary may use automated techniques for collecting internal data.
T1133 External Remote Services Persistence
Adversaries may leverage external-facing remote services to initially access and/or persist within a network.
T1530 Data from Cloud Storage Collection
Adversaries may access data from cloud storage.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-306 CWE-552

Requires verification of individual access authorizations before granting facility entry, addressing missing authentication for critical physical access.

addresses: CWE-306 CWE-552

Knowing every system allows confirmation that critical functions are not left without required authentication mechanisms.

addresses: CWE-306 CWE-552

Requires authentication gates on critical functions that must remain unavailable to anonymous public users.

addresses: CWE-306 CWE-552

Decoy implementations of critical functions without authentication lure and record attackers probing for missing auth checks.

addresses: CWE-306

Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.

addresses: CWE-306

Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.

addresses: CWE-306

Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.

addresses: CWE-552

Controls on authorized publication limit files and directories with nonpublic data from becoming accessible to external parties.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-03 full match
prevents

Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.

PR.AA-05 mostly match
prevents

Enforcing least-privilege permissions and authorization policies directly prevents unauthorized file/directory exposure.

PR.IR-01 mostly match
prevents

Logical segmentation and access protections stop external parties from reaching files that should remain internal.

PR.AA-01 partial match
prevents

Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.

PR.DS-01 partial match
prevents

Data-at-rest protections such as encryption or ACLs reduce the impact of unintended file exposure.

PR.PS-01 partial match
prevents

Hardened configuration baselines commonly include file-system permission settings that limit external access.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

The control explicitly calls for authentication before any critical function is reached, eliminating the possibility of bypassing authentication for high-value operations.

mitigates

By tracing and retrieving all copies of information stored on endpoint and portable devices, the control reduces the likelihood that files remain accessible outside the organization’s security perimeter.

mitigates

Labeling information according to its sensitivity and specifying corresponding protection measures makes it less probable that files or directories containing sensitive content will be left accessible to external parties.

prevents

Mandating authentication requirements for critical functions at the requirements-gathering stage ensures that essential operations are not left unprotected by missing login or verification mechanisms.

mitigates

Including asset location and ownership in the inventory, combined with secure disposal procedures, decreases the chance that files or directories remain accessible to external parties after they should have been removed or restricted.

mitigates

Solid perimeters and locked external access points stop files, devices, or directories containing sensitive data from being reachable by external parties who could otherwise walk in or break in.
