One of our readers, a Tyler Technologies's customer, reported to us that he found this morning the Bomgar client (BeyondTrust) installed on one of his servers. There is an ongoing discussion on Reddit with the same kind of reports.
On September 23rd, Brian Krebs posted an article about an attack against Tyler Technologies. Yesterday, the post was updated with the following communication from Tyler Technologies:
We apologize for the late-night communications, but we wanted to pass along important information as soon as possible. We recently learned that two clients have report suspicious logins to their systems using Tyler credentials. Although we are not aware of any malicious activity on client systems and we have not been able to investigate or determine the details regarding these logins, we wanted to let you know immediately so that you can take action to protect your systems
If you're also one of their customers, it could be interesting to have a look at suspicious remote access.
