hdesknet.com.br Content Scraper: Research, Ban

pool.hdesknet.com.br is part of the fix-website-errors.com by Semalt SEO content scraper campaign, huge and very annoying. I wish they would just stop scraping my site. This botnet is huge and does not seem to want to end. It started with keywords-monitoring-success and free-video-tool.com, which then involved Virtua and megared.net.mx. The vast majority of these content scraper bots reside in Brazil and South America, but there are others from Italy and the US.

Thankfully, only one ip range kills this.

ipredator.se: Research, Ban

ipredator.se is a Swedish VPN service that is comment spamming my site.

fix-website-errors.com by Semalt: Research, Ban

fix-website-errors.com is a new content scraper campaign from Semalt. It follows from the keywords-monitoring-your-success.com and free-video-tool.com campaign, which I have already banned. That botnet was huge. They involved virtua in Brazil as well. Damn them.

Anyway, they hit your site, you track them down, ban them, rinse and repeat.

bb.sky.com Content Scraper: Research, Ban

bb.sky.com is a regular content scraper on my site, so I have decided to track them down. I finally figured out their hex IP address, so I can target ranges better.

Sky is a very large TV and internet provider in the Uk. They have a huge range of IPs.

Site hits:
5ad4e517.bb.sky.com 90.212.229.12 90.212.0.0 – 90.213.255.255
027e2f4c.bb.sky.com 2.126.47.76 2.126.0.0 – 2.126.255.255
5ad00af4.bb.sky.com 90.208.10.244 90.208.0.0 – 90.209.255.255

megared.net.mx: Research, Ban

This is part of the keywords-monitoring-your-success.com, free-video-tool.com Semalt Botnet that spread to other South American hosts, but they have changed the referrer name slightly to keywords-monitoring-success.com. This host is tricky because they only provide the last 2 octets of the IP address, leaving me to guess the first two.

Here is my clue: customer-qro-199-67.megared.net.mx

There are clues to the same pattern used by megared.net.mx, using a variety of new 2 initial octets combined with the last 2 from the host name. While I only have this one IP as a content scraper, their reputation is one of an email spammer. I guess they moved into a newer but related business model.

virtua.com.br Content Scraper: Research, Ban

Persistent this botnet is. It’s like a virus that mutates but does not go away. Or an itch you scratch but does not stop. virtua.com.br has a content scraping bot going at my site that I need to stop. virtua.com.br is part of a large Semalt-led botnet I am trying to remove. They have no website. The host addresses I receive on my access log do not resolve, and there’s nothing specific on Google. I’m just giving this a simple domain ban to see how it goes. They also have a huge number of IP blocks, as they are connected to Akamai in the US.

keywords-monitoring-your-success.com and free-video-tool.com: Semalt Botnet

Both keywords-monitoring-your-success.com and free-video-tool.com are Semalt tools for content scraping. This botnet is pretty extensive and tiring to kill.

The raw access log entries look seemingly legit, but being referred from the two Semalt tools, they could not be legit users.

These host names and Ip address, masquerading as valid browsers, took up a lot of my bandwidth. This botnet used mainly companies from Brazil such as TELEFÔNICA BRASIL, Vivo, Global Village, Brasil Telecom, Yawl, portalmail but also used a bunch of Italian and US companies as well.

Virtua.com.br continues to content scrape for Semalt. I have a separate research report on them.
