The site was hacked at around 16:00 British time on Sunday 12 September. The hacker copied files to another part of the web space but did not interfere with the Forum files in any way. No infection was introduced as the files copied were part of a phishing scam. Targets of the scam, not UC members, were sent emails purporting to come from VISA and were directed to a fake VISA site, which comprised the copied files hosted by UC. The scam was detected by an anti-phishing watchdog at around 11:00 British time on Monday 13 September, which contacted the company hosting unsungcomposers.com. They suspended the site and emailed me. Unfortunately I was away from the computer all day yesterday and so did not read the email until this morning. The problem was quickly resolved with the host company and the site was reactivated.
The password for accessing the site's files has been changed, all the files added by the hacker have been removed. The hacker also added a database to the site's set of MySQL databases. Obviously, this has also been removed, but that cleaning process reverted the databases to their pre-attack state. So, any posts made or new members who joined after about 16:00 on Sunday will have been lost. I'm very sorry about that but it was unavoidable.
