I thought I had seen a previous discussion around here about these odd UA syntax things but searches and pages of looking doesn't pull them up so - is anyone else seeing these things recently? The entire UA is
"=Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.204 Safari/534.16"
coming from Paramount Technology PARAMOUNT which is within Frontline Data Services, Inc VORTECH:
216.81.64.0 - 216.81.71.255
216.81.64.0/21
That same UA is coming in from Webhosting.Net:
67.215.160.0 - 67.215.191.255
67.215.160.0/19
The other weirdo is:
"'Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)'"
Coming in from INAP-SJE-PALOALTOTECHOPS:
64.74.215.0 - 64.74.215.255
64.74.215.0/24
Mostly looking for assorted vulnerabilities. Obvious bots, 403s mean "keep trying".
