Title
=====
NISCC Briefing - Targeted Trojan E-mail Attacks

Detail
====== 

You may have seen in the UK national press articles relating to targeted 
Trojan e-mail attacks at industry and government.

The articles relate to a warning that has been issued by the National
Infrastructure Security Coordination Centre as NISCC Briefing 08/2005.  
The briefing can be found here:

http://www.niscc.gov.uk/niscc/docs/ttea.pdf

Key points discussed in the article:

   A series of trojanised email attacks are targeting UK
   Government and companies.

     . The attackers' aim appears to be covert gathering and
       transmitting of commercially or economically valuable
       information.

     . Trojans are delivered either in email attachments or through
       links to a website.

     . IP addresses used for sending emails and controlling trojans, 
	 along with email header information, are often linked to the 
	 Far-East. 

     . The emails employ social engineering, including use of a
       spoofed sender address and information relevant to the
       recipient's job or interests to entice them into opening the
       documents.

     . Once installed on a user machine, trojans may be used to
       obtain passwords, scan networks, exfiltrate information and
       launch further attacks.

     . Anti-virus software and firewalls do not give complete
       protection. Trojans can communicate with the attackers
       using common ports (e.g. HTTP, DNS, SSL) and can be
       modified to avoid anti-virus detection.
