I run a cyber security firm called Bluflame Security. On our subdomain
lab.bluflamesecurity.com we have an email sign up box for people to sign up for our newsletter. All it is, is a simple php script that gets the user input and then sends me or my other business partner an email with the persons email.
Although recently it looks like we are getting targeted.
I have been getting almost 4 user signups per day from random emails with Russian names from the email provider
mail.ru and only from there. It is very strange.
I understand that it is probably a bot, but why would a bot be putting the email in there and nothing else? Instead of sending spam, it seems to be providing us with a very large collection of
mail.ru email addresses.
What would be the reason for this besides spamming me with email applications? I am considering running some recon on some of the addresses to figure out who they are.
