Browser alerts about a download with a URL:
mapuser?providerid={number}&userid={longcapitalstring} ({number} bytes)
It gives me the option to save. This looks incredibly suspicious, but it also looks like some type of tracker since both providerid
and userid
look like identifiers of some type.
Is this a possible malware, virus or other potentially harmful file?
Thanks to all; I had to hunt this down, but I found the URL domain origin:
usync.nexage.com
That's all it provides. usync.nexage.com
and then mapuser?providerid={number}&userid={longcapitalstring}
. I get a 404. This also look suspicious because it appears to look like USNYC, but it's actually misspelled, which is a common technique in compromise.
http://host/path?query
) one could try to lookup what the server returns (but even this can change depending on location, type of browser, time ... - so it is not fully reliable). With only partial information like you provided one could maybe check who owns the domain (or at least claims to own) but not really much more.
