Phishing Activity Trends
Report for December, 2006
Summarization of December Report Findings
 The number of recorded crimeware applications saw a major increase of 110 variants in December reaching 340,
the greatest number recorded by the APWG – and the largest single-month increase ever recorded by the group.
 The number of phishing spoof sites dropped considerably to 28,531 in December 2006. This is significantly lower
than November (37,439), but it is perhaps due to phishers taking their usual holiday vacation.  APWG saw a total of146 brands being hijacked in December, a rise of 26 brands and the fourth highest recorded by the APWG.  This
month saw a substantial decrease in time-live for phishing sites to just 4 days, down from 4.5 days in November anddown from 5.3 days in December 2005.

Phishing Defined and Report Scope
Phishing is a form of online identity theft that employs both social engineering and technical subterfuge to steal
consumers' personal identity data and financial account credentials. Social-engineering schemes use 'spoofed' emails to lead consumers to counterfeit websites designed to trick recipients into divulging financial data such asaccount usernames and passwords. Hijacking brand names of banks, e-retailers and credit card companies, phishers
often convince recipients to respond. Technical subterfuge schemes plant crimeware onto PCs to steal credentials
directly, often using key logging systems to intercept consumers online account user names and passwords, and tocorrupt local and remote navigational infrastructures to misdirect consumers to counterfeit websites and to authentic
websites through phisher-controlled proxies that can be used to monitor and intercept consumers’ keystrokes.
The monthly Phishing Activity Trends Report analyzes phishing attacks reported to the Anti-Phishing Working Group(APWG) via its member companies, Global Research Partners, the organization’s website at
http://www.antiphishing.org and email submission to reportphishing@antiphishing.org. The APWG phishing attack
repository is the Internet’s most comprehensive archive of email fraud and phishing activity. The APWG additionallymeasures the evolution, proliferation and propagation of crimeware drawing from the independent research of ourmember companies. In the second half of this report are tabulations of crimeware statistics and reportage on specificcriminal software detected by our member researchers.

APWG is continuing to refine and develop our tracking and reporting methodology. We have recently re-instated thetracking and reporting of unique phishing reports (email campaigns) in addition to unique phishing sites. An email
campaign is a unique email sent out to multiple users, directing them to a specific phishing web site, (multiplecampaigns may point to the same web site). APWG counts unique phishing report emails as those in a given monthwith the same subject line in the email.
APWG also tracks the number of unique phishing websites. This is now determined by unique base URLs of thephishing sites.
APWG is also tracking crimeware instances (unique software applications as determined by MD5 hash of thecrimeware sample) as well as unique sties that are distributing crimeware (typically via browser drive-by exploits).

Phishing Email Reports and Phishing Site Trends for December 2006
The total number of unique phishing reports submitted to APWG in December 2006 was 23,787 – a decrease of over
two thousand attacks from November. This is a count of unique phishing email reports received by the APWG fromthe public, its members and its research partners.

PROJECT: Crimeware
Crimeware Taxonomy & Samples According to Classification in December 2006
PROJECT: Crimeware categorizes crimeware attacks as follows, though the taxonomy will grow as variations inattack code are spawned:

Phishing-based Trojans - Keyloggers
Definition: Crimeware code which is designed with the intent of collecting information on the end-user in order tosteal those users' credentials. Unlike most generic keyloggers, phishing-based keyloggers have tracking components
which attempt to monitor specific actions (and specific organizations, most importantly financial institutions and online
retailers and ecommerce merchants) in order to target specific information, the most common are; access to financial
based websites, ecommerce sites, and web-based mail sites.

That number represents an increase of more than 43 percent from the previous high of 237 variations – and some 62
percent higher than the December-to-December mean of 210 variants. APWG analysts believe the increase is largely
due to increased and better use of software tools to automate the creation and testing of new variants.

Phishing-based Trojans – Redirectors
Definition: Crimeware code which is designed with the intent of redirecting end-users network traffic to a location
where it was not intended to go to. This includes crimeware that changes hosts files and other DNS specificinformation, crimeware browser-helper objects that redirect users to fraudulent sites, and crimeware that may install a
network level driver or filter to redirect users to fraudulent locations. All of these must be installed with the intention ofcompromising information which could lead to identify theft or other credentials being taken with criminal intent.
Along with phishing-based keyloggers we are seeing high increases in traffic redirectors. In particular the highest
volume is in malicious code which simply modifies your DNS server settings or your hosts file to redirect either somespecific DNS lookups or all DNS lookups to a fraudulent DNS server. The fraudulent server replies with “good”
answers for most domains, however when they want to direct you to a fraudulent one, they simply modify their nameserver responses. This is particularly effective because the attackers can redirect any of the users requests at any
time and the end-users have very little indication that this is happening as they could be typing in the address on theirown and not following an email or Instant Messaging lure.
Phishing-based Trojans & Downloader’s Hosting Countries (by IP address) in December
The chart below represents a breakdown of the websites which were classified during December as hosting malicious
code in the form of either a phishing-based keylogger or a Trojan downloader which downloads a keylogger.
The United States is the top geographic location with 42.54%

The rest of the breakdown was as follows; China 7.73%, Russia 4.06%, Republic of Korea 3.35%, Brazil

About the Anti-Phishing Working GroupThe Anti-Phishing Working Group (APWG) is an industry association focused on eliminating the identity theft and fraudthat result from the growing problem of phishing and email spoofing. The organization provides a forum to discussphishing issues, define the scope of the phishing problem in terms of hard and soft costs, and share information andbest practices for eliminating the problem. Where appropriate, the APWG will also look to share this information withlaw enforcement.
Membership is open to qualified financial institutions, online retailers, ISPs, the law enforcement community, andsolutions providers. There are more than 1500 companies and government agencies participating in the APWG andmore than 2600 members. Note that because phishing attacks and email fraud are sensitive subjects for manyorganizations that do business online, the APWG has a policy of maintaining the confidentiality of member
organizations.
The website of the Anti-Phishing Working Group is http://www.antiphishing.org. It serves as a public and industry
resource for information about the problem of phishing and email fraud, including identification and promotion ofpragmatic technical solutions that can provide immediate protection and benefits against phishing attacks. The
analysis, forensics, and archival of phishing attacks to the website are currently powered by Tumbleweed
Communications' Message Protection Lab.
The APWG, a 501c6 tax-exempted corporation, was founded by Tumbleweed Communications and a number ofmember banks, financial services institutions, and e-commerce providers. It held its first meeting in November 2003 inSan Francisco and in June 2004 was incorporated as an independent corporation controlled by its steering committee,
its board and its executives.
