Virus can ruin a business

I want to tell you about a case that happened at the beginning of this week with my project YPAG.RU (according to attendance it is comparable to the yellow pages of Yell.ru )



Google Trends data
')
The directory has a section of free tenders http://www.ypag.ru/tenders/ , to which you can subscribe and receive newsletters, which inform about new tenders. The service is popular and has a large subscriber base.

In the evening, complaints began to come that we were sending spam to our subscribers; 100-200 letters were sent to one box of the same content. In the letters, links lead to our tenders. Design and design of the mailing completely licked from our mailing. That day the robot did not send mailings. It immediately became clear that the action was aimed at destroying the image of the project.

Began to understand, one of our administrators found a Trojan. It is not determined by any known antivirus. We have a good system analyst, he picked it up - Trojan only hooks on the server administrator passwords (BD, cron (nothing else interested him)). How he got to him is hard to imagine. Admin intelligent and stupid to send him a letter - "Look here girls" will not work. We tried to figure out who the recipient is, sending goes to the bourgeois mailer mail2web.com. It is clear that to get some information from them is not realistic.

Spammed 5 days !!!

The base left 5% of subscribers !!!

This is how you can kill a business in 5 days, which was built for several years!
