Source code of what is believed to be the first worm to specifically target Oracle databases has been released on the internet.
The worm was posted anonymously to the Full Disclosure security mailing list earlier this week, and security experts have warned Oracle users to make sure their databases are as secure as possible following its appearance.
It is believed that the proof-of-concept worm, which in itself is not that damaging, could prompt future attacks on Oracle software.
Once on a network, the worm scans for Oracle databases. When it finds one, it attempts to log in using several default username and password combinations.
If it gets access, the worm creates a table in the compromised database, according to the SANS Internet Storm Center, a worldwide security body that tracks network threats.
SANS said that in its current state the worm was not a big threat but should be treated as an “early warning sign for future variants of the worm, which include additional propagation methods”.
