An OSINT investigation into one of our attackers

Published on March 5, 2020 by

On December 11, 2019 we have received 31,866 HTTP requests from the IP 81.171.107.57. Below are few sample log entries:

81.171.107.57 - - [11/Dec/2019:13:52:37 +0000] "POST /login HTTP/1.1" 200 7448

This IP address logged into intelx.io with the email address “testeur.1@live.fr” on 11.12.2019 13:44:59. The IP address space 81.171.107.0/24 is owned by https://privado.io/ – a VPN provider.

However, 30 seconds earlier, the same user logged in with the IP 90.118.11.30. That IP address belongs to the telecom provider Orange:

The account testeur.1@live.fr signed up at intelx.io on 2019-12-11 13:29:41 using the IPv6 2a01:cb1c:3e7:d500:2cbc:202:4e89:793b, which is also owned by Orange France.

testeur.1@live.fr

Of course we would use our own search engine to find information about the attacker: https://intelx.io/?s=testeur.1@live.fr

The first result shows a SQL record at the hacking forum cracked.to:

INSERT INTO `mybb_users` VALUES ('234852', 'ericpompier', '$2y$12$OwDnC91.sCimfleGaHDzK.7VzqCrSaOPcaH.z2kWvr8jZJ8jHGqEq', 'eWwwAciL', 'MVdK6y3YfPeqyvBYQ08GZmwof3sQs6XIOs6egfuUlKxJtMqFyg', 'testeur.1@live.fr', '7', '0', '', '', '', '2', '', '0', '', '1560073804', '1561582600', '1560964307', '1561582563', '', '0', '', '', '', '', '', 'all', '', '1', '0', '0', '0', '1', '0', '1', '0', '1', '0', 'linear', '1', '1', '1', '1', '1', '1', '0', '0', '0', '', '', '', '0', '0', '', '', '0', '0', '0', '0', '', '', '', '0', '0', '0', 0x2A01CB1C03D0C8004CBB659841E0FE70, 0x2A01CB1C03D0C800417A4418025C83E0, '', '1716', '1', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '1', '1', '0', '', '0', '0.00', '1', '0', '0', '0', '', '1', '1', '2', '0', '0', '0', '0', '[]', '1', null, null, null, '1', '', '', '0', '0', '0', '', '', '', '', '', '0', '', '', '', '0', '0', '0', '1', '0', '0', '0', '6', '0', '0', '0', '', '0', '', '0', '0', '0', '', '', '', '', '', '', '', '', '', '', '0', '', 'mybb_bcrypt', '0', ''); 

It reveals the username “ericpompier”. https://cracked.to/ericpompier shows the user signed up on 09 June, 2019 and wrote 12 posts – mostly saying “thank you” to unlock the OPs (original posters) “hidden links”:
