I am sorry, but I do not understand any of this.
What is a 'Netbus trojan'?
Who was trying to do what to whom? Please expand in layman's terms.
Should we be taking any action? Should we be worried?

So it seems that someone at IBM Netherlands is now interested in our activities. Please let us know about any reply you get from Abuse@IBM.net

For information:
'Netbus' is a remote administration 'Trojan' program which allows a remote hacker to get any information from your computer including passwords. He can execute programs in your computer, copy files, read mail, plant other trojans or viruses, monitor the keystrokes etc. When you are connected, anyone with the Netbus Clientprogram can sneak in to your computer without your permission or knowledge. For more information do a search using 'Netbus Trojan'.

Colin, what you need is some help. You might naturally think of
contacting IBM's Information Security Practice in Amsterdam. Oh
guess what? That's in the Netherlands.

Before you do you might just consider page 25 of IBM's Annual
report for 1999. Get it from http://www.ibm.com follow links to
Investors.

For those who would rather not dirty themselves in such perilous
transit then here's the text (Copyright IBM Corporation - yeah...
Copyright on a dirty joke. What next?): Editor's comments in
brackets.

INFORMATION SECURITY PRACTICE
amsterdam the netherlands [ed : you got it folks ISP is a Nation, the
but the fair City of Amsterdam is simply a common a common noun
and The Netherlands not a Nation - Lou's educating us in the Lou
World. Thank You Oh Great One!]

Well anyway we continue...

Nanette (top left window... [Ed " with the telescope snooping,
That's Lou's telescoper not mine."],Han (center)and Daniel
(top right) are on the wanted list [ed."Very prophetic but rather
light on names Lou"]). Our customers pay them and their teams
of industry specialists [ed. "which industries... snooping?"]
and "ethical hackers" [Ed "We know already IBM isn't ethical so
what is an "ethical hacker"?]to exploit business vulnerablities and attack computer
systems .....

Read Lou's oroginal to believe.

Hope the Trojan drew a Big Blank with you Colin. Spot on report.
Move to Security State Black. Webmaster, advise on counter
measures.

The item referred to by Boudicca can be found in the IBM Annual Report 1999 - see the URL:
"http://www.ibm.com/annualreport/1999/"

There is a picture taken at night showing 3 people behind windows in a lighted upstairs room. The text reads:
----------------------------------------
Information Security Practice
Amsterdam the Netherlands

Nanette (top left window), Han(center) and Daniel(top right) are on the wanted list. Our customers pay them and their teams of industry specialists and "ethical hackers" to exploit business vulnerabilities and attack computer systems in order to stress-test company defenses and evaluate risks. As security moves to the top of customers' agendas, with growing requirements to protect against theft, industrial espionage and fraud, IBM's information security practice is doubling its revenue annually.
-------------------------------------------

The trace of the Netbus Trojan attack shows that the attempt came from IBM Netherlands, via Belgium and the UK IBM networks.


For those concerned about external invasion of their PCs when connected to the internet, there is a good article on page 104 of the March 2001 PC MAGAZINE (www.pcmag.co.uk). This article, "Defence Strategy", reviews a number of 'personal firewalls':

1. BlackIce Defender 2.1 - www.networkice.com
2. McAfee Personal firewall - www.mcafee.co.uk
3. Norton Personal Firewall 2.0 - www.symantec.com/region/uk
4. SafeGuard Personal Firewall 1.0 - www.ultimaco.com
5. Sphinx - www.biodata.com
6. ZoneAlarm Pro - www.zonelabs.com

Prices range from £25 to £50

Hope that helps
Alan Murphy (Webmaster)

I suggest you should be worried at about the same level as you worry about viruses, or
a bit less. Viruses tend to do some damage, scanners are more interested in getting
something valuable from your files. You can buy protection against either fairly cheaply
and if it keeps itself up-to-date by fetching info on the latest dangers electronically it
will be good protection. (One of the other appends has details of recommended "firewalls"
that thwart the scanners.)

[If you think it is IBM doing the scanning, as hinted in some of the messages, then discount
the advice above. Worry because there is nothing you can do - the super-experts can, I expect,
bypass any off-the-shelf protection.]

If you run Unix on your box, you can fake your IP address. For info, what was the IP address that tried to attack you. Email me if you prefer

You must escalate this until you get resolution. While I worked at IBM, them sort of activity was absolutely forbidden. The proxies will keep a log of who initiated the attack, and you should demand a proper investigation.
