<img src=logos/hyas.png height=60>
HYAS Insight integration to MISP provides direct, high volume access to HYAS Insight data. It enables investigators and analysts to understand and defend against cyber adversaries and their infrastructure.
- **features**:
>This Module takes the IP Address, Domain, URL, Email, Phone Number, MD5, SHA1, Sha256, SHA512 MISP Attributes as input to query the HYAS Insight API.
> The results of the HYAS Insight API are than are then returned and parsed into Hyas Insight Objects.
>
>An API key is required to submit queries to the HYAS Insight API.
>
- **input**:
>A MISP attribute of type IP Address(ip-src, ip-dst), Domain(hostname, domain), Email Address(email, email-src, email-dst, target-email, whois-registrant-email), Phone Number(phone-number, whois-registrant-phone), MDS(md5, x509-fingerprint-md5, ja3-fingerprint-md5, hassh-md5, hasshserver-md5), SHA1(sha1, x509-fingerprint-sha1), SHA256(sha256, x509-fingerprint-sha256), SHA512(sha512)
- **output**:
>Hyas Insight objects, resulting from the query on the HYAS Insight API.
- **references**:
>https://www.hyas.com/hyas-insight/
- **requirements**:
>A HYAS Insight API Key.

#### [variotdbs](https://github.com/MISP/misp-modules/tree/main/misp_modules/modules/expansion/variotdbs.py)
<img src=logos/variot.png height=60>
An expansion module to query the VARIoT db API for more information about a vulnerability.
- **features**:
>The module takes a vulnerability attribute as input and queries que VARIoT db API to gather additional information.
>
>The `vuln` endpoint is queried first to look for additional information about the vulnerability itself.
>
>The `exploits` endpoint is also queried then to look for the information of the potential related exploits, which are parsed and added to the results using the `exploit` object template.
- **input**:
>Vulnerability attribute.
- **output**:
>Additional information about the vulnerability, as it is stored on the VARIoT db, about the vulnerability itself, and the potential related exploits.
- **references**:
>https://www.variotdbs.pl/
- **requirements**:
>A VARIoT db API key (if you do not want to be limited to 100 queries / day)
