Ongoing widespread credential stuffing attack

There is a widespread credential stuffing attack by malicious actors attempting to hack into Forum accounts using credentials exposed in data breaches at other sites or have been harvested by Data Stealing Trojans

Most notable IP  109.107.166.230

Do a search and you'll see 300+ recorded events in four days.

Every time I look, the number id events increase.  If you look at the sparse Evidence entries, they are coincidental.

Re: Ongoing widespread credential stuffing attack

I noticed a brief flurry of dormant (not used for several years) forum accounts suddenly promoting crypto pumps, all from this IP; clearly accounts had been compromised. A quick check of the IP revealed that the entire 109.107.166.0/24 range was registered to an individual in UA. Simply banning that IP range seems to have solved the immediate problem for our forum.

I just looked.  The IP first shows as a reported event on; 1/14'23.  Two months later, the count has more than doubled.

Found 825 entries for "109.107.166.230"
