Ban Web Server Traffic

Web Server Traffic Should be Banned

Opinions will differ about putting a ban on web server traffic. There are those who want their blogs and websites free from malicious activity, safe and secure for genuine valuable visitors. Then there are those who think there should be no restrictions on web traffic and activity (some even think spam is not bad).

Let’s clarify the web traffic we’re talking about. We’re not talking of banning referer traffic i.e. traffic from good back-links from websites resulting in genuine visitors.

Most of these attacks are coming from USA based web hosting services. One particular top level service provider, Provo Unified Layer, stands out above the rest as the most hacked network. Many 2nd tier providers use Provo Unified Layer infrastructure including Bluehost and Hostmonster. Of the hosts using Provo Unified Layer infrastructure, Bluehost is ahead of the pack in having hosted sites participating in the botnet. (Read more about Bluehost and the Botnet).

Roubaix Ovh Systems

Roubaix Ovh Systems – Most Dangerous Host?

Is Roubaix Ovh Systems, a hosting and Internet Service Provider in France, one of the most dangerous ISPs and hosts in the world? We could be justified in thinking so. At least out of ISPs and hosting companies in the Western economic zone, outside of former Soviet Union states.

When you see a spambot active on your site, a hacking attempt, or a trackback spammer, there’s a pretty good chance it’s coming from an IP registered to Roubaix Ovh Systems, or another Ovh Systems IP.

Roubaix Ovh Systems Banned on Sight

We (Graphicline Web & Technology) have seen so much bad activity from IPs traced back to Roubaix Ovh Systems we now ban all their IPs as soon as I find them. Activity from all other OVH Systems networks are watched carefully

Rove Digital Botnet Take-Down

Cyber-Criminals Arrested, US Offices Closed

A cyber criminal network operated by Estonian company Rove Digital was taken down on November 8 2011 in a combined effort involving the FBI (Federal Bureau of Investigation of the USA) and the Estonian Police in co-operation with Trend Micro.

Rove Digital operated a botnet consisting over four million (4 000 000) bots on computers infected with a class of malware known as ‘DNSChangers’. The infected systems will typically have their Domain Name Server (DNS) changed to point to foreign IP addresses.

Rove digital appears on the surface as a legitimate business, with established offices in Tartu, Estonia. They are the parent company of several other operations, including Esthost, Estdomains, Cernel, UkrTelegroup and many less well-known shell companies.

Rove Digital used a variety of  criminal methods to earn money from the DNS changers. The cyber crime network has operated from 2006.
