Good afternoon,

I send this email to inform that on Saturday, October 29th, between 12:00
and 19:45 (CEST) approximately, the services of Firmaprofesional were
subject to a denial of service attack (DoS), which, thanks to the company's
security systems did not have a notable impact. There were some microcuts
at: 12:03:38, 12:24:38, 14:25:38, 17:45:48, 18:01:38, 18:16:58, 18:32:48,
19 : 36: 28 (CEST).

After investigating and ruling out different possible causes, we found that
it was, indeed, a DoS attack. The following IP addresses were identified as
attackers and proceeded to block them:

   - 167.114.41.148
   - 167.114.41.149
   - 149.56.154.192
   - 149.56.180.253
   - 45.195.133.125

From that moment, no more attacks were received until last Monday 1st of
Octobre at 14:30 CEST, and until Yesterday, the attack persisted, although,
again, it is not affecting the services provided by Firmaprofesional.

Just to keep you informed.

Best regards,
