Using MISP to share vulnerability information efficiently

Using MISP to share vulnerability information efficiently

Software and hardware vulnerabilities are often discussed, shared, prepared, analysed and reviewed before publication. This process can be tedious as it often includes multiple exchanges between the parties involved, including reporters, proxy-reporters, coordinators, editors and even impacted parties. Some vulnerabilities might be shared and exchanged among trusted parties for months before being officially disclosed. This can generate a significant workload on the staff dealing with a security team, vulnerability assessment team or CNA (CVE Numbering Authorities).

MISP 2.4.73 released

A new version of MISP 2.4.73 has been released including new features, improvements and bug fixes.

A new module type Cortex has been introduced allowing for easy integration of MISP and Cortex. Cortex is the analysis engine part of the TheHive Project which supports expansion services from Cortex within MISP. A new setting has been added to support Cortex similarly to MISP expansion modules where you set the remote Cortex instance. MISP includes a new Cortex attribute type to allow for the raw analysis to be stored along with the event for subsequent analysis.

MISP 2.4.71 released

A new version of MISP 2.4.71 has been released including new features, improvements and important bug fixes.

• Distribution can now be set in the free-text and modules import.
• Password complexity default tightened to allow passphrase-like in addition to password.
• Password regexp (can be considered a CTF-challenge for some users) is now available as a hint.
• API restsearch has been significantly improved allowing to support alternate download types from the restsearch (currently OpenIOC is supported). OpenIOC export and CIDR tool refactored.
• Organisation blacklist is now enabled by default and sample UUIDs/organisations are now blacklisted by default.
• API The “proposal to delete flag” is now available in the API output.
• Improved error handling when failing to add a tag.
• API Event history is now available via the API.
• Set comment field to an empty string in the attributes pre-validation (to avoid null comment field).
• Correlation can now be disabled for site admin even if (s)he is not the owner.

Various bugs fixed in the sharing group synchronisation and delegation. Improvements to the UI popups when using low-resolution (aka potato displays).

MISP 2.4.70 released

A new version of MISP 2.4.70 has been released including new features, improvements and important bug fixes.

• A significant improvement has been introduced to the MISP user-interface to make it more accessible especially for visually impaired users.
• API improvements introduced to allow adding several attributes in one go.
• API extended to support the functionality of adding and editing MISP servers.
• A simple update feature from the user-interface was introduced to ease the update process of MISP.
• New attribute types (hex, sigma and impfuzzy) have been introduced for new misp-objects and to improve the support of the new sigma format. Sigma is a generic signature format for SIEM Systems. This new attribute type will help the development of a sigma converter via misp-modules.
• Test and diagnostic for the MISP server synchronisation has been significantly improved. The old legacy and mangle sync for very old MISP instances (2.3x) has been removed in an effort to make the code cleaner and improve the synchronisation process with recent MISP instances.

Many other bugs fixed and minor features added.

MISP 2.4.68 released

A new version of MISP 2.4.68 has been released including multiple bug fixes and improvements.

• Enable sync permissions for read-only accounts.
• Upload org logo can now be performed via the org edit/view interface.
• An option to disable cached export has been added for low disk space servers.

Blacklisting of deleted events is now enabled by default. This feature existed before but was not enabled by default. This feature allows MISP users to ensure that deleted events never propagate back to their instance. The blacklist can easily be managed from the MISP interface. As this feature is a default behaviour that a large majority of the MISP community needs, we have decided to enable this feature by default starting from version 2.4.68.

Sighting the next level

Sighting is an endless topic of discussion. This is a required feature especially when information or indicators are regularly shared to gather feedback from users said shared data. Adequate sightings can be an incredible source of information in order to describe the life-time of an indicator, its evolution and especially to ensure the understanding of indicators among a group of users using the information to detect, mitigate or block malicious activities in their infrastructures. The potential is endless, potentially being a significant gain for organised communities of infosec professionals sharing information or even serve as a requirement for advanced algorithms ranging from machine learning to reinforcement learning. But to reach such a state of a feedback loop, you first require a functional model of sighting.
