Dockerfile for MalwareDB

There are two Dockerfiles:

• MalwareDB/Dockerfile builds a container with both Postgres with the extensions and MalwareDB.
• Postgres/Dockerfile builds Postgres only with the extensions. This is for installations where MalwareDB should be separate from the database, or by those who'd like to use the similarity extensions.

Both use Postgres 15 from Debian 12 Bookworm.

Postgres Extensions

Postgres is installed, and extensions built with extensions for:

• LZJD
• SSDeep
• SDHash
• TLSH

To use the extensions, you have to add them to each database schema you wish to use them as the schema owner, or as the postgres user. SQL commands:

• CREATE OR REPLACE FUNCTION lzjd_compare(TEXT, TEXT) RETURNS INTEGER AS 'lzjd_psql.so', 'pg_lzjd_compare' LANGUAGE 'c';
• CREATE OR REPLACE FUNCTION fuzzy_hash_compare(TEXT, TEXT) RETURNS INTEGER AS 'ssdeep_psql.so', 'pg_fuzzy_hash_compare' LANGUAGE 'c';
• CREATE OR REPLACE FUNCTION sdhash_compare(TEXT, TEXT) RETURNS INTEGER AS 'sdhash_psql.so', 'pg_sdhash_compare' LANGUAGE 'c';
• CREATE OR REPLACE FUNCTION tlsh_compare(TEXT, TEXT) RETURNS INTEGER AS 'tlsh_psql.so', 'pg_tlsh_compare' LANGUAGE 'c';

Be sure to set the admin password for Postgres via the POSTGRES_PASSWORD environment variable, shown below.

$ git clone https://github.com/malwaredb/docker.git
$ cd docker/Postgres
$ docker build -t postgres-similarity/latest .
$ mkdir pg_data
$ docker run -v `pwd`/pg_data:/var/lib/postgresql/data -p 5432:5432 -e POSTGRES_PASSWORD=yoursecurepassword postgres-similarity/latest

MalwareDB

The images are about ~4GB, could probably be smaller. The SQL commands for adding the fuzzy hash functions above are added by the start.sh script at container start. The Postgres server won't be accessible outside the container.

You should use this with an existing Postgres data instance so you can have the administrative settings in order (users, groups, sources). At present, the administrative functions aren't available over the HTTP API.

$ git clone https://github.com/malwaredb/docker.git
$ cd docker/MalwareDB
$ docker build -t malwaredb/latest .
$ mkdir mdb_data
$ mkdir mdb_data/db
$ mkdir mdb_data/samples
$ docker run -v `pwd`/mdb_data/db:/var/lib/postgresql/data -v `pwd`/samples:/malware_samples -p 8080:8080 malwaredb/latest
