MISP v2.4.99 released – Malware Information Sharing Platform & Threat Sharing
MISP – Malware Information Sharing Platform and Threat Sharing
MISP, Malware Information Sharing Platform, and Threat Sharing is an open source software solution for collecting, storing, distributing and sharing cybersecurity indicators and threat about cybersecurity incidents analysis and malware analysis. MISP is designed by and for incident analysts, security and ICT professionals or malware reverser to support their day-to-day operations to share structured information efficiently.
The objective of MISP is to foster the sharing of structured information within the security community and abroad. MISP provides functionalities to support the exchange of information but also the consumption of the information by Network Intrusion Detection System (NIDS), LIDS but also log analysis tools, SIEMs.
MISP, Malware Information Sharing Platform, and Threat Sharing, core functionalities are:
- An efficient IOC and indicators database allowing to store technical and non-technical information about malware samples, incidents, attackers and intelligence.
- Automatic correlation finding relationships between attributes and indicators from malware attacks campaigns or analysis.
- A flexible data model where complex objects can be expressed and linked together to express threat intelligence, incidents or connected elements.
- Built-in sharing functionality to ease data sharing using a different model of distributions. MISP can synchronize automatically events and attributes among different MISP. Advanced filtering functionalities can be used to meet each organization sharing policy including a flexible sharing group capacity and an attribute level distribution mechanisms.
- An intuitive user-interface for end-users to create, update and collaborate on events and attributes/indicators. A graphical interface to navigate seamlessly between events and their correlations. Advanced filtering functionalities and warning list to help the analysts to contribute events and attributes.
- storing data in a structured format (allowing the automated use of the database for various purposes) with an extensive support of cybersecurity indicators along fraud indicators as in the financial sector.
- export: generating IDS, OpenIOC, plain text, CSV, MISP XML or JSON output to integrate with other systems (network IDS, host IDS, custom tools), STIX (XML and JSON), NIDS export (Suricata, Snort, and Bro) or RPZ zone. Many other formats easily added via the misp-modules.
- import: bulk-import, batch-import, import from OpenIOC, GFI sandbox, ThreatConnect CSV. Many other formats easily added via the misp-modules.
- Flexible free text import tool to ease the integration of unstructured reports into MISP.
- A gentle system to collaborate on events and attributes allowing MISP users to propose changes or updates to attributes/indicators.
- data-sharing: automatically exchange and synchronization with other parties and trust-groups using MISP.
- delegating of sharing: allows a simple pseudo-anonymous mechanism to delegate publication of event/indicators to another organization.
- Flexible API to integrate MISP with your own solutions. MISP is bundled with PyMISP which is a flexible Python Library to fetch, add or update events attributes, handle malware samples or search for attributes.
- Adjustable taxonomy to classify and tag events following your own classification schemes or existing classification. The taxonomy can be local to your MISP but also shareable among MISP instances.
- Intelligence vocabularies called MISP galaxy and bundled with existing threat actors, malware, RAT, ransomware or MITRE ATT&CK which can be easily linked with events in MISP.
- Expansion modules in Python to expand MISP with your own services or activate already available misp-modules.
- Sighting support to get observations from organizations concerning shared indicators and attributes. Sighting can be contributed via MISP user-interface, API as MISP document or STIX sighting documents.
- STIX support: export data in the STIX format (XML and JSON). Additional STIX import and export is supported by MISP-STIX-Converter or MISP-Taxii-Server.
- Integrated encryption and signing of the notifications via PGP and/or S/MIME depending of the user preferences.
Exchanging info results in faster detection of targeted attacks and improves the detection ratio while reducing the false positives. We also avoid reversing similar malware as we know very fast that others team or organizations who already analyzed a specific malware.
A sample event encoded in MISP:
A new version of MISP (2.4.99) has been released with improvements in the UI, API, STIX import and a fixed critical security vulnerability.
Thanks to Francois-Xavier Stellamans from NCI Agency Cyber Security who reported a critical vulnerability in the STIX 1 import code. The vulnerability allows a malicious authenticated user to inject commands via an incorrectly escaped variable name (the original name of the STIX file). We strongly urge users to update their MISP instance to the latest version. We also replaced the mechanism of storing the original uploaded files on ingestion with a standardised function that will process the files without passing them to external tools – this reusable system will avoid any similar issues in the future if new similar mechanisms are introduced. CVE allocation is pending (the page will be updated when we receive it).
This release includes the following changes:
- The following attribute types were added x509-fingerprint-md5 and x509 -fingerprint-sha256 to the network activity category.
- A new CLI interface to cleanup the brute-force protection entries from MISP.
- Some warning messages inconsistencies were fixed in the UI.
- Added a warning when a site administrator is trying to edit an event not belonging to the organisation of the site admin.
- [API] Object edit has been fixed to return the object in the correct format.
- When editing an object to add new attributes, correctly set the default distribution if nothing is set.
- Many fixes and improvement in the STIX 1 and STIX 2.0 import.
- XML MISP export has been fixed.
