Leaseweb is a secure place

Recently, I had the pleasure of hosting the administrator of the site, the leading Zeus tracker site. is one of a number of sites Leaseweb supports under its Community Outreach Project to make the internet a safer and better place. Leaseweb works with many not-for-profit organizations that monitor the web for malicious activity, offering free hosting and servers in return for the information that these groups collect on suspected internet security issues.

Zeus, and it variants are so-called “Trojans.” Trojans are files that claim to be something desirable, but in actuality are very malicious and threatening. Trojans contain code that, when triggered, cause loss, or even theft of data. For a Trojan to spread, you must open an email attachment or go to an infected site. Zeus and its variants are some of the most dangerous Trojans, stealing financial records and sending them back to its masters, who use the information for financial crimes.

As one of the largest and most respected hosts in Europe, Leaseweb has been in the forefront in combating malware, through the Community Outreach program and other initiatives. Leaseweb maintains a Security Office with highly skilled staff to ensure the safety of Leaseweb customers at all times. Abuse issues are professionally handled in a rapid manner, so that all matters are quickly resolved.

In my discussions with the administrator of, he noted one of the main reasons for badness on the internet is that some hosting providers just do not care. Leaseweb provides a strong Acceptable Use Policy protecting its own customers, as well as the broader internet. With a bad host customers can be faced with blacklisted IP ranges; bouncing emails; dDos attacks; and a general lack of security. This is not a problem at Leaseweb. recently created the SpyEye tracker to follow new variants of Zeus. It is through the tireless work of sites such as that real progress has been made to control internet malware. Leaseweb will continue to support it and other groups that are making the internet a safer place to operate. In reviewing Leaseweb’s security policies, the administrator noted: “Leaseweb is a secure place.” We appreciate the vote of confidence and will continue to work to do even better in the future.

According to Symantec, spam was down 47% in October – its lowest level in over a year – due to some recent high profile botnet busts. Most industry professionals are now aware that Leaseweb was involved in the successful Bredolab botnet takedown last month.

The Dutch Forensic Institute (NFI), together with internet security organizations GOVCERT and Fox IT were involved in monitoring and identifying the botnet.  The Armenian police were involved in the capture of the suspect behind this major cyber-crime incident.

It is a great example of how collaboration between Leaseweb and internet security organizations is helping to make the internet a much safer place. While cyber-criminals will always find new ways to infiltrate the web and target businesses and computer users, Leaseweb continues to work tirelessly to protect everyone utilizing the internet via our products and services. Working together we can win the fight against cyber-crime.

    If you take abuse so seriously, why does your abuse department never reply to abuse complaints?
    All they do is send the same standard message, no matter how many times you try to contact them. And no action is taken.
    Dear sir/madam,
    In response to your complaint I inform you.

    Have you already contacted the site owner yourself? If not, then please
    do so. If yes, please let me know his/her response. Please leave a
    durance of 48 hours, before contacting, because otherwise the website
    owner has no time to give a proper response.

    Please keep in mind that the Netherlands have a different policy
    regarding Take Down Notices, and since the website is hosted in the
    Netherlands, Dutch Law applies.
    The correct way to handle Take Down Notices is:
    Contact the uploader of the content, if not possible -> Contact the
    website owner, if not possible -> Contact website hoster, if not
    possible -> Contact ISP (that’s Leaseweb).

    If you have any questions, do not hesitate to contact us.
    Kind regards,

    Dear Eric,

    And have you done what Lesley Koomen asked you to do?
    Did you try to contact the uploader, website owner or
    the website hoster? This e-mail quote is rather onesided
    don’t you think?

    I recently submitted an illegal system intrusion report and it took 2 days to come back and request that the IP address referred to is under the care of their US abusecenter and that I should contact them directly. There was not even a microsecond of thought that a forwarding of my email would have been more expeditious. I did as requested and after about 1 week, I have no response.

    This shows a lack of duty of care. I did request to escalate to the legal department and the CEO and awaiting results.
