Users of Adminer 3.7.1 and older might have been hacked

Školení, která pořádám

An attacker from an IP address was able to modify the file which was used by Adminer version 3.7.1 (more than 7 years old) and older for syntax highlighting. The file was modified from 2020-12-29 17:34 GMT to 2020-12-30 11:20 GMT. If you used these Adminer versions to access a database in this time then change the database passwords. Newer Adminer versions are not affected as they bundle this file and don't download it.

The attacker was able to get my hosting password. I don't know how they obtained it but I've changed all the passwords and limited the IP range from which it is possible to log in. I also use 2FA for the central admin but the hosting unfortunately couldn't enforce it for just the server login. I've also checked the published Adminer versions which are unaffected and I've also searched for other possible backdoors.

I've filed a report at which is listed for reporting security issues coming from this IP address. I've also notified GetPush where the malicious code was sending the data.

This is the malicious code:

I'm sorry for any inconvenience.

Robert Vlach:

Thanks for the detailed info! Which web hosting was it, by the way?

ikona Jakub Vrána OpenID:

Váš-Hosting. They were very cooperative and I don't blame them for the incident, quite the contrary.


Hey, nobody likes being hacked.  Nobody like to admit they have been hacked.  Seems like you didn't sit on it for a year, like most tech giants (Yahoo, FaceBook etc), you just stuck your hand up and just said it.  Nobody could ask anything more of you than to let people know as soon as you can.
