U.S. Secret Service
Testimony of Mr. James A. Savage, Jr.
Deputy Special Agent in Charge-Financial Crimes Division
Before
The Senate Committee on the Judiciary
Subcommittee on Technology, Terrorism and Government Information
July 25, 2001
Madam Chairman, members of the subcommittee, thank you for the
opportunity to address the subcommittee regarding federal law
enforcement efforts in combating cyber crime to protect our nation's
infrastructures, and particularly the efforts of the Secret Service
in this regard. I am particularly pleased to be here with my colleagues
and partners in fighting cyber crime from the Federal Bureau of
Investigation and the General Services Administration.
As you know, the Secret Service was created in 1865 to address
the burgeoning problem of counterfeit currency. At that time,
it was estimated that approximately one third of all currency
in circulation was counterfeit and the government recognized the
urgent need to address this issue in order to maintain the public's
confidence in the U.S. currency. In effect, the Secret Service
was engaged in an effort to protect a critical governmental function
long before the popular notion of critical infrastructure protection
emerged.
Today, the Secret Service continues to suppress counterfeit currency
as part of its traditional role but also now includes fighting
cyber crime as part of our core mission to protect the integrity
of this nation's financial payment systems. Over time, modes and
methods of payment have evolved and so has our mission. Computers
and other "chip" devices are now the facilitators of
criminal activity or the target of such. The perpetrators involved
in the exploitation of such technology range from traditional
fraud artists to violent criminals - all of whom recognize new
opportunities and anonymous methods to expand and diversify their
criminal portfolio.
In this era of change, one constant that remains is our close
working relationship with the banking and finance sector. Our
history of cooperation with the industry is a result of our unique
responsibilities as a law enforcement bureau of the Department
of the Treasury. We believe that protection of the banking and
financial infrastructure is our "core competency" area.
Madam Chairman, there is no shortage of information, testimony,
or anecdotal evidence regarding the nature and variety of cyber-based
threats to our banking and financial infrastructures and the need
to create effective solutions. There is, however, a scarcity of
information regarding successful models to combat such crime in
today's high tech environment. That is where the Secret Service
can make a significant contribution to today's and future discussions
of successful law enforcement efforts to combat cyber crime which
play an important role in critical infrastructure protection.
The Secret Service has found a highly effective formula for combating
high tech crime - a formula that has been successfully developed
by our New York Electronic Crimes Task Force. While the Secret
Service leads this innovative effort, we do not control or dominate
the participants and the investigative agenda of the task force.
Rather, the task force provides a productive framework and collaborative
crime-fighting environment in which the resources of its participants
can be combined to effectively and efficiently make a significant
impact on electronic crimes. Other law enforcement agencies bring
additional criminal enforcement jurisdiction and resources to
the task force while representatives from private industry, such
as telecommunications providers, for instance, bring a wealth
of technical expertise.
Although based in New York City, the task force provides assistance
and conducts investigations, which span the country and often
lead overseas, harnessing disparate repositories of resources
and expertise from the academic, private and government sectors.
It is not uncommon for the New York Task Force to receive requests
for assistance directly from foreign law enforcement representatives
based upon its reputation for responsiveness and as a center of
excellence. The result is a significant impact domestically, and
occasionally abroad, as well.
Within this New York model, established in 1995, there are 50
different federal, state and local law enforcement agencies represented
as well as prosecutors, academic leaders and over 100 different
private sector corporations. The wealth of expertise and resources
that reside in this task force coupled with unprecedented information
sharing yields a highly mobile and responsive machine. In task
force investigations, local law enforcement officers hold supervisory
positions and representatives from other agencies regularly assume
the role of lead investigator. These investigations encompass
a wide range of computer-based criminal activity, involving e-commerce
frauds, intellectual property violations, telecommunications fraud,
and a wide variety of computer intrusion crimes, which affect
a variety of infrastructures.
Since 1995, the task force has charged over 800 individuals with
electronic crimes valued at more than $425 million. It has trained
over 10,000 law enforcement personnel, prosecutors, and private
industry representatives in the criminal abuses of technology
and how to prevent them. We view the New York Electronic Crimes
Task Force as the model for the partnership approach that we hope
to employ in additional venues around the country in the very
near future.
An important component in our investigative response to cyber
crime and critical infrastructure protection is the Electronic
Crimes Special Agent Program (ECSAP). This program is comprised
of approximately 175 special agents who have received extensive
training in forensic identification, preservation, and retrieval
of electronically stored evidence. Special Agents entering the
program receive specialized training in all areas of electronic
crimes, with particular emphasis on computer intrusions and forensics.
ECSAP agents are computer investigative specialists, qualified
to conduct examinations on all types of electronic evidence, including
computers, personal data assistants, telecommunications devices,
electronic organizers, scanners, and other electronic paraphernalia.
ECSAP agents understand that not only do they have an investigative
role, and that they can also help protect components of our critical
infrastructure by providing their substantive insights regarding
potential vulnerabilities and exploits which the Secret Service
discovers during an investigation.
As a specific example, in early August we will be meeting with
representatives of a major financial group, which is in the process
of developing its own computer forensic capability to bolster
its defenses against internal and external computer based frauds
and attacks. We hope to share with this prominent corporation
the lessons we have learned in establishing and maintaining our
ECSAP computer forensics program as well as explore areas for
joint endeavors in the future.
The Secret Service ECSAP program relies on the 4 year-old, Treasury-wide
Computer Investigative Specialist (CIS) initiative. All four Treasury
law enforcement bureaus - the Internal Revenue Service, Bureau
of Alcohol, Tobacco and Firearms, U.S. Customs Service, and the
U.S. Secret Service -- participate and receive training and equipment
under this program.
All four Treasury bureaus also jointly participate in curriculum
development and review, equipment design and distribution of training
assets. As a result, financial savings by all Treasury bureaus
are realized due to economies of scale. Additionally, agents from
different bureaus can work together in the field in an operational
capacity due to the compatibility of the equipment and training.
In the end, the criminal element suffers and the taxpayer benefits.
The Secret Service works cooperatively with other federal law
enforcement and Department of Defense agencies in this work, to
include the FBI and NIPC. No single agency or entity can prevent
cybercrime or protect the critical infrastructure alone, so Secret
Service agents work collaboratively with their peers in the field
to investigate crimes and overcome technical problems. I would
further add, Madam Chairman, that due to the proliferation and
complexity of cyber crime there is certainly no shortage of opportunity
to collaborate with our other Federal partners in this regard.
Because of the recognized expertise of those in ECSAP, other
law enforcement agencies regularly request training from the Secret
Service or advice concerning their own computer forensics programs.
These requests have come from agencies all across the country,
as well as foreign countries such as Italy and Thailand. The Secret
Service recognizes the need to promote international cooperation
and remains proactive in the dissemination of information to law
enforcement agencies, both domestically and internationally, regarding
program initiatives and current financial and electronic crimes
trends.
Madam Chairman, we are committed to working closely with our
law enforcement counterparts worldwide in response to cyber crime
threats to commerce and financial payment systems. This commitment
is demonstrated by our effort to expand our overseas presence.
We currently have 18 offices in foreign countries and a permanent
assignment at Interpol, as well as several overseas initiatives,
including a cyber crime task force in Indonesia. New offices have
been opened recently in Frankfurt, Lagos, and Mexico City. The
Secret Service is also considering opening new offices in Bucharest
and New Dehli. Our expanded foreign presence increases our ability
to become involved in foreign investigations that are of significant
strategic interest.
In addition to providing law enforcement with the necessary technical
training and resources, a great deal more can be accomplished
in fighting cyber crime if we are able to harness additional resources
that exist from the private sector and academia. The Secret Service
believes there is value in sharing information during the course
of our investigations with both those in the private sector and
academia who are devoting substantial resources to protecting
their networks and researching new solutions. On occasion the
Secret Service has shared case-specific information derived from
our criminal investigations after taking appropriate steps to
protect privacy concerns and ensure that there are no conflicts
with prosecutorial issues. I would add that there are many opportunities
for the law enforcement community to share information with our
private sector counterparts without fear of compromise. The Secret
Service recognizes the need for a "paradigm shift" with
respect to this type of information sharing between law enforcement
and our private sector and academic counterparts.
Finally, law enforcement in general is not sufficiently equipped
to train all those in need nor can it compete with academic institutions
of higher learning in the area of research and development. However,
our partnerships with industry and academia have demonstrated
that this should be an integral part of the solution.
Partnership concepts are an important tool and strategy in both
government and private industry to achieve greater results and
efficiencies. Unfortunately, however, partnerships cannot be legislated,
regulated, or stipulated. Nor can partnerships be purchased, traded
or incorporated. Partnerships are built between people and organizations
that recognize the value in joint collaboration toward a common
end. They are fragile entities, which need to be established and
maintained by all participants and built upon a foundation of
trust.
The Secret Service, by virtue of the protective mission for which
we are so well known, has always emphasized discretion and trust
in executing our protective duties. We learned long ago that our
agency needed the full support and confidence of local law enforcement
and certain key elements of the private sector to create and maintain
a successful and comprehensive security plan. Furthermore, we
are also keenly aware that we need to maintain a trusted relationship
with our protectees so that we can work with them and their staffs
to maintain the delicate balance between security and personal
privacy.
This predisposition towards discretion and trust naturally permeates
our investigative mission where we enjoy quiet successes with
our private sector partners. We have successfully investigated
many significant cases with the help of our private sector partners
such as network intrusions and compromises of critical information
or operating systems. In such cases, even though we have technical
expertise that is second to none, we still rely on our private
sector counterparts to collaborate with us in identifying and
preserving critical evidence to solve the case and bring the perpetrator
to justice. Equally important in such cases is conducting the
investigation in a manner that avoids unnecessary disruption or
adverse consequences to the victim or business. With the variety
of operating platforms and proprietary operating systems in the
private sector, we could not accomplish these objectives without
the direct support of our private sector counterparts.
I would like to highlight several significant cases that the
Secret Service has investigated over the years where we have protected
the U.S. financial and telecommunications systems.
In 1986, the USSS identified and prosecuted the "Legion
of Doom" hacker group for compromising the 911 system in
the southeast United States.
In 1989, the USSS, working with the FBI and other law enforcement
entities, identified and prosecuted the "Masters of Deception"
hacker group which had compromised several communications networks
in the U.S. enabling the group to identify and reveal the details
concerning on-going law enforcement wiretaps.
In 1994, the USSS conducted the first e-mail wiretap ever conducted
on the Internet as part of a telecommunications fraud investigation.
In 1997, the USSS identified and arrested a hacker responsible
for compromising a telephone network switch on the east coast,
effectively disabling power and communications to the Worcester,
MA. Airport. This resulted in the first prosecution of a juvenile
for violation of 18 USC 1030.
In 1998, the USSS and its task force partners in New York, identified
and arrested individuals who were illegally monitoring law enforcement
Mobile Data Terminals.
Madam Chairman, the USSS continues to remain engaged in these
types of significant investigations, which not only involve notable
financial losses, but also represent the exploitation of technical
vulnerabilities in and amongst interconnected computer-based systems
which support our critical infrastructures. Of particular note
is that such cases necessarily require a close working relationship
with the private sector victim to achieve success.
In fact, in one recently completed complex investigation involving
the compromise of a wireless communications carrier's network,
our case agent actually specified in the affidavit of the federal
search warrant that representatives of the victim business be
allowed to accompany federal agents in the search of the target
residence to provide technical assistance. This is unprecedented
in the law enforcement arena and underscores the level of trust
we enjoy with those we have built relationships with in the private
sector. It is also indicative of the complexity of many of these
investigations and serves to highlight the fact that we in law
enforcement must work with private industry to be an effective
crime fighting force. In approving this search warrant, the court
recognized that in certain cases involving extraordinarily complex
systems and networks, such additional technical expertise could
be a critical, and sometimes imperative, component of our investigative
efforts.
I must point out, however, that such cases are usually not publicized
without the express consent of the U.S. Attorney and the corporate
victim because it would breach our confidential relationship and
discourage the victims of electronic crimes from reporting such
incidents.
Four recently concluded investigations demonstrate the breadth
of cases the Secret Service is working, and provide concrete evidence
of the continuing success of ECSAP. The cases include the malicious
shutdown of a medical service provider's communications system,
an intrusion into a telecommunication provider's network, an attack
on a private investment company's trading network, and the disruption
of a financial institution's complete operating system and communications
network.
The first case was initiated on March 5, 2001, when a local Secret
Service field office received information that a medical diagnostic
service provider had suffered a catastrophic shutdown of its computer
network and communications system. The company reported that they
were unable to access doctor schedules, diagnostic images, patient
information, and essential hospital records, which adversely affected
their ability to provide care to patients and assist dependent
medical facilities.
Within a matter of hours, a Secret Service ECSAP agent was able
to regain control of the network by coordinating with the facility's
system administrator to temporarily shutdown and reconfigure the
computer system. The ECSAP agent also essentially "hacked"
into the compromised system, and modified compromised password
files to "lock out" the attacker. This was accomplished
while maintaining control of the computer system log files containing
evidence of how the intrusion had occurred.
Using this evidence, a federal search warrant was obtained for
the residence of a former employee of the hospital, who had recently
been terminated from his position as system administrator. Computer
equipment was seized pursuant to the warrant, the suspect admitted
to his involvement, and federal computer fraud charges are pending.
A case with obvious critical infrastructure implications was
initiated on February 20, 2001, when two major wireless telecommunications
service providers notified the New York Electronic Crimes Task
Force that they had identified two hackers in different remote
sites who were attacking their systems. These hackers were manipulating
the systems to obtain free long distance service, re-route numbers,
add calling features, forward telephone numbers, and install software
that would ensure their continued unauthorized access.
The level of access obtained by the hackers was virtually unlimited,
and had they chosen to do so, they could have shut down telephone
service over a large geographic area, including "911"
systems, as well as service to government installations and other
critical infrastructure components.
On March 20, 2001, the Secret Service simultaneously executed
search warrants in New York City and Phoenix and computer equipment
was seized at both locations. One suspect was arrested on federal
computer fraud charges, while the other suspect was questioned
and released pending a decision by the Department of Justice as
to whether or not to pursue federal charges.
The third case occurred from March 9, 2000, through March 14,
2000, when a company located in New York, NY, received several
Internet-based "denial of service" attacks on its servers.
A "denial of service" attack occurs when a perpetrator
launches malicious programs, information, codes, or commands to
a target or victim computer which causes it to shut down, thereby
denying access by legitimate customers to those computers. In
this instance, the company was a prominent provider of electronic
trading services on Wall Street.
While the attacks were still occurring, the company's CEO contacted
the Secret Service's New York Electronic Crimes Task Force. The
CEO identified a former employee as a suspect, based upon the
fact that the attacks preyed on vulnerabilities, which would only
be known to the former employee. These attacks continued through
March 13, 2000, when ECSAP agents and task force members identified
the attacking computer and arrested the former employee for violating
Title 18, USC, Section 1030 (Computer Fraud). In a post-arrest
statement, the suspect admitted that he was responsible for the
denial of service attacks. As a result of the attacks, the company
and its customers lost access to trading systems. Approximately
$3.5 million was identified in lost trading fees, commissions,
and liability as a result of the customers' inability to conduct
any trading.
The last case began just last month when a financial institution
notified local police who in turn notified the local office of
the Secret Service, that its entire banking and communications
network had been shut down. The institution reported that it was
severely crippled, as it had no access to electronic data used
in support of its ATMs, banking transactions, employee payroll
and all other critical functions. Working with the local police
and the bank's technical staff, a former employee emerged as a
suspect and electronic evidence was developed that strongly indicated
his involvement. During an ensuing interview with agents and police,
the suspect admitted to disabling the bank's system and "hacking"
an unrelated database in his attempts to exact revenge upon the
bank CEO. Federal charges are pending.
Let me emphasize the Secret Service's mission in fighting cyber
crime as it relates to the bigger picture of critical infrastructure
protection. As previously stated, we target cyber crime as it
may affect the integrity of our nation's financial payment and
banking systems. As we all know, the banking and finance sector
comprises a very critical infrastructure sector and one, which
we have historically protected and will continue to protect. In
this context, our efforts to combat cyber assaults, which target
information, and communication systems, which support the financial
sector, are parts of the larger and more comprehensive critical
infrastructure protection scheme. The whole notion of infrastructure
protection embodies an assurance and confidence in the delivery
of critical functions and services that in today's world are increasingly
interdependent and interconnected. To put this all in perspective,
the public's confidence is lost if such delivery systems and services
are unreliable, unavailable, or unpredictable regardless of the
cause of the problem.
We also recognize that our unique protective responsibilities,
including our duties as the lead federal agency for coordinating
security at National Special Security Events, demand heightened
electronic security awareness and preparation. A well-placed cyber
attack against a weak technology or support infrastructure system
can render an otherwise sound physical security plan vulnerable
and inadequate.
To further advance our efforts in this regard, the Secret Service
will soon commence a significant collaborative project with the
Software Engineering Institute (SEI) at Carnegie Mellon University
which has operated the Computer Emergency Response Team (CERT)
Coordination Center since 1988. Jointly, the Secret Service and
the SEI plan to combine expertise in developing strategies and
programs to effectively address cyber threats, which may impact
our protective and investigative missions.
Madam Chairman, it should also be noted that all deliberate infrastructure
attacks, before they rise to such a threshold, are also cyber
crimes and are likely to be dealt with initially by law enforcement
personnel, both federal and local, in the course of routine business.
In fact, I don't believe there is universal agreement as to when
a "hack" or network intrusion rises to the threshold
of an infrastructure attack and corresponding national security
event but we would all probably recognize one when it reached
catastrophic proportions.
Given this continuum and interplay between computer-based crimes
and national security issues, the Secret Service recognizes that
its role in investigating and helping to prevent computer-based
attacks against the financial sector can be significant in the
larger plan for the protection of our nation's critical infrastructures.
When we arrest a criminal who has breached and disrupted a sensitive
communications network and are able to restore the normal operation
of the host --be it a bank, telecommunications carrier, or medical
service provider -- we believe we have made a significant contribution
towards assuring the reliability of the critical systems that
the public relies upon on a daily basis. But greater satisfaction
and success are achieved when a potentially devastating incident
is prevented due to our prior involvement, participation, or sharing
of information.
As a footnote, the Secret Service met recently with representatives
of the Financial Services Information Sharing and Analysis Center
(FS/ISAC) that was created pursuant to Presidential Decision Directive
(PDD) 63. The directive mandated the Department of the Treasury
to work with members of the banking and finance sector to enhance
the security of the sector's information systems and other infrastructures,
a responsibility managed by Treasury's Assistant Secretary of
Financial Institutions. The role of the FS/ISAC is to devise a
way to share information within the financial services industry
relating to cyber threats and vulnerabilities. The Secret Service
feels that it can make a significant contribution to the work
of the FS/ISAC and is exploring common areas of interest with
the FS/ISAC, to include information sharing.
The Secret Service continues to receive requests from local law
enforcement agencies and others for assistance, and we welcome
those requests. On an increasing basis, our local field offices
and the Financial Crimes Division of the Secret Service receive
desperate pleas from local police departments for physical assistance,
training and equipment in the area of computer forensics and electronic
crimes so that they can continue to provide a professional level
of service and protection for their citizens. The Secret Service
has become an important option for local law enforcement, the
private sector and others to turn to when confronted with network
intrusions and other sophisticated electronic crimes.
Over the past 3 years, Secret Service ECSAP agents completed
2,122 examinations on computer and telecommunications equipment.
Although the Secret Service did not track the number of exams
done for other law enforcement agencies during this period, it
is estimated that some 10 to 15 percent of these examinations
fell in this category. Many of the examinations were conducted
in support of other agencies' investigations such as those involving
child pornography or homicide cases simply because the requesting
agency did not have the resources to complete the examination
itself.
We do provide assistance on a regular basis to other departments,
often sending ECSAP agents overnight to the requesting venue to
perform computer related analyses or technical consultation. In
fact, so critical was the need for even basic training in this
regard that the Secret Service joined forces with the International
Association of Chiefs of Police and the National Institute for
Justice to create the "Best Practices Guide to Searching
and Seizing Electronic Evidence" which is designed for the
line officer and detective alike. Madam Chairman, with your permission,
I would like to submit a copy of this guide for the record.
We have also worked with this group to produce the interactive,
computer-based training program known as "Forward Edge"
which takes the next step in training officers to conduct electronic
crime investigations. Forward Edge incorporates virtual reality
features as it presents three different investigative scenarios
to the trainee. It also provides investigative options and technical
support to develop the case. Copies of state computer crime laws
for each of the fifty states as well as corresponding sample affidavits
are also part of the two-CD training program and are immediately
accessible for instant implementation.
Thus far we have dispensed over 220,000 "Best Practices
Guides" to local and federal law enforcement officers and
we will soon distribute, free of charge, over 20,000 Forward Edge
training CDs.
In an additional effort to further enhance information sharing
between the law enforcement community and the financial industry,
the Secret Service recently created the "E Library"
Internet website which serves as a mechanism for all members to
post specific information, images and alerts relating to fictitious
financial instruments, counterfeit checks, and credit card skimming
devices. This website is accessible free of charge to all members
of the law enforcement and banking communities and is the only
such tool of its kind.
In today's high tech criminal environment, the challenge to federal
law enforcement and government is to identify existing repositories
of expertise and provide a framework for inclusion and productive
collaboration amongst the many government agencies and their respective
industry and academic counterparts. The Secret Service is convinced
that building trusted partnerships with the private sector and
its Federal and local law enforcement partners is the model for
combating electronic crimes in the information age.
Madam Chairman, that concludes my prepared statement, and I would
be happy to answer any questions that you or other members of
the subcommittee may have.
