The malicious payload is at [donotclick]scriptuserreported.org/close/keys-importance-mention.php hosted on 5.39.37.31 and there are no surprises that this is OVH in France.. but wait a minute because this is in a little suballocated block thusly:

inetnum:        5.39.37.24 - 5.39.37.31
netname:        n2p3DoHost
descr:          DoHost n2 p3
country:        FR
admin-c:        OTC2-RIPE
tech-c:         OTC2-RIPE
status:         ASSIGNED PA
mnt-by:         OVH-MNT
source:         RIPE # Filtered

Let's start with the server at 5.39.37.31 which is distributing the Blackhole Exploit Kit (report here). This server also hosts the following potentially malicious domains:
pesteringpricelinecom.net
resolveconsolidate.net
scriptuserreported.org
provingmoa.com

Go back a few IPs to 5.39.37.28 and there is are a couple of work-at-home scam sites:
workhomeheres01.com
workhomeheres02.com

There's also a work-at-home scam on 5.39.37.24:
makeworkhome12.pl

5.39.37.26 appears to be hosting a control panel for the Neutrino Exploit kit:
myadminspanels.info
supermyadminspanels.info

So you can pretty much assume that 5.39.37.24/29 is a sewer and you should block the lot. Who is n2p3DoHost? Well, I don't know.. but there's one more clue at 5.39.37.29 which is the domain rl-host.net. The WHOIS details for rl-host.net are anonymised, but on the day of registration were:

    Queste Julien
    Email:julien@queste.fr
    50 rue Arthur lamendin
    62330 isbergues
    France
    Tel: +33.649836105

Does M. Queste own this /29? If he does, then it looks like he has some very bad customers..

Minimum blocklist:
