FYI,

8078 was just released that is suppose to address the issue.

Same here...I installed 8077 this morning when I get in after reading the email and I'm getting Fallout alerts like crazy. I don't have as many as you, but people just starting coming in.

@bbilut @OGMaverick,

For the time being I would recommend rolling this back to 8076. The Fallout siganture has actually been around since 8074, but whatever modification PA has done to the signature is a tad to broad at the moment.

I'm rolling back to 8076 and I'll report back what happens. I was getting a detection about every minute or multiple per minute with 8077.

 

Edit: 8076 seems to have stopped the mass amount of alerts.

Hello,

Looks like this was the emergency update that came out last night:

I usually set my dynamic updates with a threshold that will allow the updates to bake since they have released bum updates in the past. I understand there are some environments where this is not possible.

Yeah, we are also getting a lot of the Threat ID 30650 events.  All events seem to include a *.min.js or *.js file name.

I had the same files - *.js

I do the same... I'm usually a week behind because their updates have burnt me in the past several times. This one seemed urgent so I manually updated this morning. I guess that was a mistake.
