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 authenticwebsites 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.

Methodology
APWG is continuing to refine and develop our tracking and reporting methodology. We have re-instated the tracking
and reporting of unique phishing reports (email campaigns) in addition to unique phishing sites. An email campaign isa unique email sent out to multiple users, directing them to a specific phishing web site, (multiple campaigns maypoint to the same web site). APWG counts unique phishing report emails as those in a given month with 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 September 2007
The total number of unique phishing reports submitted to APWG in September 2007 was 38,514, an increase ofnearly 13,000 reports from August, indicating larger campaigns and more effective sending techniques. This is a countof unique phishing email reports received by the APWG from the public, its members and its research partners.

The Phishing Attack Trends Report is published monthly by the Anti-Phishing Working Group, an industry and law
enforcement association focused on eliminating the identity theft and fraud that result from the growing problem of phishing,crimeware and email spoofing. For further information, please contact APWG Deputy Secretary General Foy Shiver at404.434.7282. Data and analyses for the Phishing Attack Trends Report has been donated by the following companies:

April - September 2007 Brand-Domain Pairs Measurement
The following chart combines statistics for the last five months based on brands phished, unique domains, uniquedomain/brand pairs and unique URLs. Brand/domain pairs count the unique instances of a domain being used totarget a specific brand. Example: if several URLs targeting a brand - but are hosted on the same domain - thisbrand/domain pair would be counted as one instead of several. Forensic utility: If the number of unique URLs isgreater than the number of brand/domain pairs, it indicates many URLs are being hosted on the same domain totarget the same brand. Knowing how many URLs occur with each domain indicates the approximate number ofattacking domains a brandholding victim needs to locate and neutralize. Since Phishing-prevention technologies (likebrowser and email blocking) require the full URL, it is useful to understand the general number of unique URLs thatoccur per domain.
While the number of unique brands reported to APWG by consumers has fallen, the number of unique phishing emails
has increased. This seems to indicate that phishers are becoming increasingly targeted, and are making great efforts
to ensure that their phishing emails get through spam and fraud filters.

Number ofReported Brands
September saw a major
decrease in hijacked brands
to 92.
Some of the bigger non-bankbrands have made significant
and measurable
improvements in their antiphishing and user
authentication technologies.
These measures appear to beworking, as we are seeing adecline in the amount ofreported phishing for severalof those brands.
However, we are seeingsome major attacks against
well known banking brands
that haven't been heavily
targeted for some time.

Most Targeted Industry Sectors in September 2007
Financial Services
continue to be the mosttargeted industry sector
at 91.3% of all attacks inthe month of September.
APWG is also seeing
more phishing against
some of the larger
Internet retailers and theonline job websites. The
targetting of online job
sites is likely linked tothe massive identity theftcases that have involved
these sites in recentmonths.
US and UK taxauthorities continued tobe spoofed in phishingattacks against
consumers.

PROJECT: Crimeware
Crimeware Taxonomy & Samples According to Classification in September 2007
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 onlineretailers 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.

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 September
The chart below represents a breakdown of the websites which were classified during September as hosting malicious
code in the form of either a phishing-based keylogger or a Trojan downloader which downloads a keylogger.
The United States continues to be the top hosting country with 53.82%.
The rest of the breakdown was as follows; Republic of Korea 8.20%, Russian Federation 6.51%, China 6.49%, Brazil
6.33%, Argentina 4.11%, United Kingdom 3.95%, Romania 3.64%, Poland 3.56% and India with 3.39%.
