Lankford, Senate Finance Committee Republicans Demand Answers from the IRS on ProPublica Data Leak
OKLAHOMA CITY, OK – Senator James Lankford (R-OK) joined Senate Finance Committee Republicans in demanding answers from the Internal Revenue Service (IRS) on the ProPublica data leak. Nearly six months after ProPublica began disclosing confidential, private, and legally protected taxpayer information, the IRS and the Biden Administration continue to show little regard about the haphazard handling of private taxpayer data.
ProPublica unabatedly continues to publish articles naming individual taxpayers while the IRS, the Department of the Treasury, the Federal Bureau of Investigation, and the Department of Justice have all failed to identify the source or sources of the leaked information.
In their letter, the Senators wrote, “[…]ProPublica continues to publish what appears to be confidential taxpayer information that is protected by law, and as Commissioner, you have been a proponent of the IRS being allowed access to even more information from taxpayers and a significant and mandatory enforcement budget. The fact that the source of the information ProPublica continues to publish remains unknown means that the ability of the IRS to safeguard information already entrusted to it also remains unknown. It is possible that ProPublica obtained whatever information it has at one time from a specific source. However, if the ProPublica information was leaked or hacked from the IRS, and the IRS is unable to even determine if a leak or hack took place, this could indicate an ongoing and persistent problem with IRS information technology (IT) systems and the ability of the IRS to safeguard taxpayer information.”
The letter notes known deficiencies in IRS systems and highlights data and privacy security vulnerabilities involved in contractor relationships. The Members also request further, detailed information about the IRS’s efforts to determine a source of the leaks, and what the IRS has done to resolve open recommendations for curing deficiencies.
“As we enter month six with no information about how ProPublica obtained protected taxpayer information, the risks we highlighted in this letter are of growing concern,” the letter continues. “It is our constitutional obligation to ensure that IRS enforcement remains effective, and that requires the IRS to properly secure taxpayer information.”
The leak or hack of private taxpayer information and unauthorized disclosure by advocates at ProPublica cannot be ignored or swept under the rug. The public needs to know that personal information provided to the IRS remains confidential, and not available for targeting or political agendas, especially in light of current efforts to expand private information collection on American taxpayers.
The full text of the letter is below and HERE.
Dear Commissioner Rettig:
We are writing regarding the series of articles published by the website ProPublica that appear to be based on confidential taxpayer information that potentially was leaked or hacked from the Internal Revenue Service (IRS). On June 8, 2021, ProPublica published, “The Secret IRS Files: Trove of Never-Before-Seen Records Reveal How the Wealthiest Avoid Income Tax.”1 This was the first in a series of articles that ProPublica continues to publish with no indication that any progress has been made by any federal agency regarding identification of the source or sources of the taxpayer information. Despite clear and ongoing evidence of a threat of a data breach, in response to a letter sent to you by Senators Grassley and Crapo, you responded in part that “We do not yet know whether there has been a data breach or a threat of a data breach.” Your letter of September 13, 2021, also notes that “We do not yet have any information concerning the source of the alleged taxpayer information published by ProPublica.”
These responses are very troubling, particularly because ProPublica continues to publish what appears to be confidential taxpayer information that is protected by law, and as Commissioner, you have been a proponent of the IRS being allowed access to even more information from taxpayers and a significant and mandatory enforcement budget.2 The fact that the source of the information ProPublica continues to publish remains unknown means that the ability of the IRS to safeguard information already entrusted to it also remains unknown. It is possible that ProPublica obtained whatever information it hasat one time from a specific source. However, if the ProPublica information was leaked or hacked from the IRS, and the IRS is unable to even determine if a leak or hack took place, this could indicate an ongoingand persistent problem with IRS information technology (IT) systems and the ability of the IRS tosafeguard taxpayer information.
IRS Systems Are Notoriously Ineffective
Even before ProPublica began publishing articles utilizing taxpayer information, significant issues with IRS IT systems were well documented. In fact, the struggles of the IRS to modernize IT systems is something of an old chestnut in tax policy circles. Aside from a reliance on COBOL which is referred to as “geriatric code,” it is also reported that the “IRS main software "Master File" was developed in 1962 and uses nine-track tape for data storage. None of the IRS programs have ever been that well coordinated.” In written testimony delivered before the Subcommittee on Government Operations of the House Committee on Oversight and Reform on October 7, 2020, the Government Accountability Office (GAO) Director of Information Technology and Cybersecurity stated the following:
In May 2020, GAO reported that new and continuing deficiencies in information system security controls over financial and tax processing systems included deficiencies related to access controls, segregation ofduties, and other areas. These collectively represented a significant deficiency in risks of unauthorizedaccess to, modification of, or disclosure of financial reporting and taxpayer data and disruption of criticaloperations.4
In a recent audit, GAO also “identified new information system control deficiencies related to access controls and security management that contributed to IRS’s continuing significant deficiency in its internal control over financial reporting systems.” When this report was published in May 2021, there were a total of 120 open recommendations to the IRS with 96 of those recommendations falling within theaudit area of information systems. Among the open recommendations, GAO “identified one deficiency in access controls related to cryptography (i.e., encryption).” Specifically, “IRS did not enforce cryptographic protocols used for authentication and data integrity in a system environment that processes taxpayer data in accordance with agency policy and National Institute of Standards and Technology guidance.”8
GAO is not the only oversight entity that has recently identified IRS deficiencies with encryption of taxpayer data. On September 27, 2021, the Treasury Inspector General for Tax Administration (TIGTA)issued a report titled, “The Data at Rest Encryption Program Has Made Progress With Identifying Encryption Solutions, but Project Management Needs Improvement.” The report notes that “[t]he IRS has made progress to identify and test encryption and key management solutions for use with certain types of systems. However, it has not deployed this technology. The protection of the vast amounts of taxpayer information collected and maintained by the IRS is critical to maintaining a basic level of confidence in the fair application and enforcement of our nation’s tax laws. We believe many taxpayers would be shockedthat the IRS has not already implemented a functioning system for protecting the information stored on its systems. According to the IRS, more than 167 million individual income tax returns had been filed by theweek ending October 22, 2021, for the 2021 filing season.
More recently, in a September 28, 2021, report on IRS information security modernization, TIGTA reportedon ineffectiveness of risk management. TIGTA concluded that:
Until the IRS takes steps to improve its security program deficiencies and fully implement all security program components in compliance with FISMA [Federal Information Security Modernization Act] requirements, taxpayer data could be vulnerable to inappropriate and undetected use, modification, or disclosure.
IRS Contractor Relationships Introduce Additional Security Vulnerabilities
The IRS’s relationships with contractors represent an additional vulnerability to the security of IRS systems. Private contractors serve a vital role in helping the IRS efficiently perform its duties, which makesit vitally important adequate security measures are in place.
For example, TIGTA has previously recommended that the IRS implement end-to-end encryption in transferring taxpayer data to Private Collection Agencies (PCAs). The IRS utilizes PCAs as part of a very successful program to pursue and collect tax debt that the IRS has elected not to pursue. It is important that any taxpayer information that is transferred as part of this program is fully protected against unauthorized access and disclosure. The September 27, 2021, TIGTA report notes that “the IRS verified the taxpayer information was being encrypted through e-mail verification with the PCAs. However, the IRS dropped the ball on its end.
According to TIGTA, “PCA information residing at the IRS had not been encrypted in the production environment.”
Moreover, the TIGTA report raises questions about any other contractors the IRS has allowed to access taxpayer information. For example, a 2018 article published by Bloomberg Tax describes how “[a] contract with … Palantir Technologies will give the IRS new firepower to pursue tax cheats by connecting the dots in millions of tax filings, bank transactions, phone records, and even social media posts.” Inreporting on an earlier contract with Palantir, the story notes that in 2013 the IRS “spent $30.8 million on a five-year contract with 13 Federal LLC, a Palantir subsidiary, and granted it access to files for more than 1 million people, according to a privacy audit report.” No doubt these contractors do important work thatfacilitates the fair and effective working of our federal tax system. However, this is a massive amount of taxpayer information. And it is critical that the IRS ensure contractors are complying with their obligation to safeguard it. These requirements are documented in IRS Publication 4812, Contractor Security & Privacy Controls. In part, this publication requires that
Contractors and subcontractors shall have adequate programs in place to protect the information received from unauthorized use, access, and disclosure. The contractor’s programs for protecting information received must include documented notification to employees and subcontractors (at any tier) regarding, the importance of protecting returns and return information.
IRS is Expanding Private Data Acquisitions and Requesting Unprecedented Funding
In a contract that may have been finalized by Treasury and the IRS with Babel Street, Inc., the IRS seeks “a third-party digital media search and reporting solution that captures information from public facing digital media records that can be used in taxpayer compliance and tax administration cases.”19 Such data apparently will be obtained for the IRS by artificial intelligence (AI)-enabled software that scrubs the internet for information on taxpayers, including current and historical publicly posted communications, images, videos, and cached pages of those taxpayers. The “solution,” according to a solicitation/contract order by Treasury to Babel Street, Inc. is supposed to provide: “Secure access to publicly available information without posing a security and public policy perception risk.”
Gathering troves of taxpayer information from anywhere it can possibly be found by AI algorithmic robots should be counted as a public policy perception risk in and of itself. Having the IRS gather suchinformation to combine with troves of personal taxpayer information already possessed by the IRSamplifies our concerns about data security in IRS systems.
The IRS appears to be expanding its collection of information on taxpayers to house it in systems with known security deficiencies and shortfalls. Meanwhile, the IRS and Treasury are advocating for an unprecedented, nearly $80 billion, amount of mandatory funding from general taxpayer resources. In the funding scheme being advocated, the IRS is to be provided with a mandatory stream of $80 billion, after which the IRS would report to Congress on how it plans to use the funds—that is; fund now, plan later. Such a scheme, in the face of ongoing alleged privacy leaks of what appear to be IRS information, the source(s) of which no federal agency appears to have any knowledge, and in the face of known serious deficiencies in IRS data protections, defines irresponsibility.
As we enter month six with no information about how ProPublica obtained protected taxpayer information, the risks we highlighted in this letter are of growing concern. It is our constitutional obligation to ensure that IRS enforcement remains effective, and that requires the IRS to properly secure taxpayer information. Accordingly, we request responses to the following questions by December 15, 2021.
1. Do you have any update regarding the responses provided to Senators Grassley and Crapo in your letter of September 13, 2021, where you stated you did “not yet know whether there has been a data breach or a threat of a data breach,” and did “not yet have any information concerning the source of the alleged taxpayer information published by ProPublica”?
2. How many full-time equivalent employees have been tasked to determine whether or not IRS data and systems have been compromised in any way, such as through a leak or hack, since thepublication of articles by ProPublica in June of 2021?
3. What is the status of the IRS’s efforts to resolve the 120 open GAO recommendations—particularly the recommendations relating to information systems, that are noted in the May 4, 2021, GAO publication “Management Report: Internal Revenue Service Needs to ImproveFinancial Reporting and Information System Controls?”
a. What is the timeline for ensuring that the IRS resolves all recommendations?
4. What is the status of the IRS’s efforts to resolve the deficiency related to encryption identifiedin GAO’s May 4 report as well as to fully comply with the recommendations made by TIGTA inthe September 2021, report on data at rest encryption.
5. In a “Management’s Response” provided in response to a TIGTA recommendation to encrypt taxpayer data before it is provided to PCAs, the IRS notes that it “will implement a solution that will ensure that data at rest is encrypted prior to being transferred from the IRS to PCAs.”
a. How many contractors of any type, not just PCAs, has the IRS provided taxpayerinformation to that has not been encrypted over the past year and the past 10 years?
b. How is the IRS transmitting the data and what safeguards are used to ensuretaxpayer data is subject to all the protections afforded by law?
6.How many contractors does the IRS have active contracts with that involve the sharing ofprotected taxpayer information and how many contracts have involved sharing of taxpayerinformation over the past 10 years?
7.Please identify the holders of all contracts and sub-contracts over the past 10 years whereprotected taxpayer information has been transmitted outside the IRS or access granted toindividuals employed by a contractor or sub-contractor.
8.Of taxpayer information provided to contractors, IRS Publication 4812 requires that“Contractors and subcontractors shall have adequate programs in place to protect theinformation received from unauthorized use, access, and disclosure.”
a. Please provide examples of any contract language that the IRS requirescontractors to agree to that concerns the protection of taxpayer information.
b. How does the IRS monitor compliance with the requirements of IRS Publication 4812and how often does it confirm compliance?
c. Does the IRS require that all contractors maintain activity logs that detail allinstances of contractor employee access to taxpayer information?
d. Does the IRS have regular access to activity logs maintained by contractors or do theyneed to be specifically requested?
e. Is the IRS aware of the unauthorized use, access, or disclosure of taxpayerinformation, by any contractor, sub-contractor, or employee over the past 10 years?Please break down incidents by contractor self-reported incidents and incidentsdetected by the IRS or TIGTA.
9. Several of the stories published by ProPublica disclose taxpayer information of specifictaxpayers. Has the IRS examined data held by the IRS on those specific taxpayers anddetermined the full universe of individuals, including IRS employees, contractors and sub-contractors that have potentially been able to access that information?
10. Why does the IRS need data from AI-enabled programs and algorithms that scrape data from the internet about taxpayers? What protections will the IRS put in place to ensure that whatever troves of such data are aggregated to analyze and profile an individual, they will be secure and fully protected from release and will not be used for any improper targeting efforts by the IRS?
11. Out of $44.9 billion requested in the partisan Build Back Better bill for IRS enforcement, to include funds for, inter alia, “investigative technology” and “digital asset monitoring and compliance activities,” how much would the IRS plan to use on additional digital surveillance oftaxpayers, and for what reasons?
Thank you for your attention to these important matters.
