Evil network: Didjief LLC / DIGIEF-NET AS48709 (91.200.242.0/23)

Didjief  LLC - or to give its full (and presumably fake) name "Didjief Internation Kulinari Koncept LLC" - runs a wholly malicious netblock in the 91.200.242.0/23 (91.200.240.0 - 91.200.243.255) range which includes a variety of malware sites, fake businesses, fake software and other malicious sites that should be blocked.

Many of these sites have wholly ficticious WHOIS entries or are registered through known black hat registrars. Some examples and references are:

A simple Google search bring up lots of matches that indicate malicious activity, for example 91.200.240 and 91.200.242. There are also fake business sites such as Adclickmarket.com which gives WHOIS contact details as:

    Ad Click Market Ltd.
    AdClickMarket        (info@adclickmarket.com)
    PO Box 279
    Alderley Edge
    Cheshire,SK9 7UQ
    GB
    Tel. +44.2854327

There is no company in the UK with the name Ad Click Market Ltd according to Companies House.

There is also another group of fake businesses using the "Advertising German Group" name, such as traveleshop.biz (also implicated in malware distribution here):

    Advertising German Group (AGG)
    Niclas Kappel        (niclas.kappel@yahoo.com)
    Kurt-Schumacher-Str. 5
    Bonn
    Nordrhein-Westfalen,D-53110
    DE
    Tel. +490.2284290

According to SiteVet, the AS48709 block has been bad ever since it was allocated late last year. The digief.eu domain associated with it is currently suspended, and it isn't clear if the WHOIS details for the netblock are accurate (they are probably not).
