Microsoft Bots overwritting URL parameter values
Hi Awesome Brain Trust of Adobe Analytics (ABToA),
We are observing some visits where our campaign tracking code parameter values (in our case 'xcid') and even some Google UTM parameter values contain values that are not generated by our team (for that we use Claravine/TrackingFirst).
Has anyone else seen anything like this?
The look auto-generated...and until earlier this year were only a few hundred visits/month, but this year we are seeing a jump to over 5,000 per month.
They are being overwritten from tactics in all channels from google and bing advertising to emails we've sent out via Marketo.
We've tracked the IP addresses and they all seem to be coming from Microsoft IPs, so we assume it is some kind of bot.
Here are some examples of the variants...the numeric part will have tons of values so the seem to be auto generated:
b-b_48882
ccd-ccd_31350
dbagc-ace_48167
fkg0039
fz-6eec_54792
fz-be_31072
fz-ge_bdbeg
Most seem to come from MS domains:

URL examples:

For now we will put hits from the IP addresses we've ID'd into our 'exclude bot' segment.
Any thoughts?
Thanks!
