Introduction
In 2024, Cellebrite assisted in over 5 million cases worldwide, showcasing its pivotal role in modern law enforcement intelligence but sparking heated debates over privacy and ethics (Manson & Murphy, 2024). As mobile devices have become indispensable to daily life, they have also become crucial repositories of actionable intelligence in criminal investigations. Cellebrite, a leader in digital forensics tools, has enabled law enforcement intelligence to collect, process, and analyze data from mobile devices, including encrypted and locked phones. These capabilities have been transformative in supporting high-profile cases such as the San Bernardino shooting and the Trump shooter investigation. However, using such tools has also raised significant legal and ethical questions regarding privacy and constitutional rights.
This paper examines Cellebrite’s role in law enforcement intelligence, focusing on its applications for data collection, processing, analysis, and reporting, the legal frameworks governing its use, and the ethical dilemmas posed by balancing public safety with individual privacy. Through an analysis of specific case studies and relevant legal precedents, this study argues that while Cellebrite’s tools are essential for modern intelligence operations, their use must be regulated through stronger legal oversight and ethical guidelines to ensure compliance with constitutional freedoms and prevent misuse.
The Evolution of Digital Forensics
The increasing reliance on mobile devices for personal and professional activities has made them central to modern criminal investigations. As digital footprints expand, they leave behind a wealth of information that could potentially be used as evidence in court (Delgado, n.d., p. 1). This shift has necessitated the development of sophisticated digital forensics tools to extract and analyze data from these devices.
Cellebrite has emerged as a leader in this field, offering advanced tools like the Universal Forensic Extraction Device (UFED) for data extraction, providing critical support in intelligence collection and processing for law enforcement (salvationdata, 2023). The company’s tools have become instrumental in solving a wide variety of crimes, from homicides and rapes to drug cases and cyberstalking (“Crime Scene BureauForensic Analysis and Cyber Tech Services Unit,” n.d.).
Law enforcement agencies’ widespread adoption of mobile device forensic tools (MDFTs) underscores their critical role in modern investigations. According to Koepke et al. (2020), the 50 largest local police departments, state law enforcement agencies in all 50 states, and at least 25 of the 50 largest sheriff’s offices have purchased or used MDFTs (p. 35). This pervasive use has led to significant financial investments, with some agencies spending hundreds of thousands of dollars on Cellebrithe and other MDFTs (Koepke et al., 2020, p. 36).

Case Studies in Law Enforcement Intelligence
San Bernardino Case
The San Bernardino case of 2015 brought national attention to the challenges of accessing encrypted devices in terrorism investigations. On 2 December 2015, Syed Rizwan Farook and Tashfeen Malik carried out a terrorist attack in San Bernardino, California, killing 14 people and injuring 22 others. The FBI recovered Farook’s locked iPhone 5C, which they believed could contain crucial evidence about the attack and potential collaborators.
The case sparked a legal battle between the FBI and Apple. The FBI requested that Apple create a backdoor to bypass the iPhone’s encryption. Apple refused, citing concerns about user privacy and the potential to misuse such a tool. This standoff highlighted the tension between national security interests and individual privacy rights in the digital age.
Eventually, the FBI announced that they had accessed the phone’s contents with the help of an unnamed third party, widely speculated to be Cellebrite (Sewell, as cited in Kahney, 2019). This case underscored the limitations of existing forensic tools in accessing newer, more secure devices and the potential for companies like Cellebrite to provide breakthrough solutions in high-stakes investigations.
The San Bernardino case set a precedent for future digital privacy and security debates. It demonstrated the critical role of digital forensics in terrorism investigations and the challenges posed by increasingly sophisticated encryption technologies. The case also highlighted the need for a balanced approach that respects national security concerns and individual privacy rights.
Trump Shooter Case
On 13 July 2024, during a campaign rally in Butler, Pennsylvania, former President Donald Trump became the target of an assassination attempt. The incident, which left one spectator dead and two others injured, brought renewed attention to the capabilities of digital forensics in high-profile investigations.
The shooter, identified as Thomas Matthew Crooks, a 20-year-old man from Bethel Park, Pennsylvania, was quickly neutralized by Secret Service agents. In the aftermath, investigators faced the challenge of uncovering Crooks’ motives and potential connections. Central to this investigation was Crooks’ smartphone, a newer model Samsung device running the Android operating system (OS).
While the Pittsburgh FBI Office had a Cellebrite license, they encountered difficulties cracking the passcode on Crooks’ phone. This highlighted a critical limitation in their standard toolkit and the need for more advanced solutions in high-stakes cases. Recognizing the urgency and high-profile nature of the case, Cellebrite took an unusual step. The company provided the FBI with an unreleased, cutting-edge update specifically designed to tackle the security measures on Crooks’ device model (Manson & Murphy, 2024).
FBI technicians could unlock Crooks’ smartphone in approximately 40 minutes using this advanced update provided. This rapid access to the device’s contents was crucial in the early stages of the investigation, allowing agents to quickly pursue leads and assess potential ongoing threats (Manson & Murphy, 2024).
This case highlighted Cellebrite’s ability to provide bespoke solutions for high-profile investigations, demonstrating their capacity for rapid, targeted development of forensic tools. It also underscored the ongoing challenges in mobile device forensics, as each new device and operating system update can potentially render existing extraction methods obsolete.
North Carolina Drug Prosecution Case
In a 2023 North Carolina drug prosecution case, Cellebrite’s tools were crucial in providing evidence that impacted the trial’s outcome. The case involved a defendant suspected of dealing drugs, and the evidence extracted from the defendant’s cellphone using Cellebrite’s technology became a key point of contention.
Law enforcement officers used a “Cellebrite extraction report” to recover text messages and photographs from the defendant’s phone. These digital artifacts ranged from 20 October 2018 to 25 February 2019 and included an undated photo of a crystalline substance taken on 25 December 2018. The prosecution argued that this evidence was “relevant information” to demonstrate the defendant’s knowledge, motive, and intent to commit the charged offenses (THE COURT OF APPEALS OF NORTH CAROLINA, 2023, p. 503).
The defense filed a motion to exclude the evidence from the extraction report, arguing that it violated Rule 404(b) of the North Carolina Rules of Evidence. However, the trial court denied this motion, allowing the evidence to be admitted. The Court of Appeals of North Carolina later upheld this decision, stating that the trial court did not err in admitting the prior bad act evidence in the form of text messages from the defendant’s cell phone (THE COURT OF APPEALS OF NORTH CAROLINA, 2023, p. 501).
The court argued that the evidence was relevant because it corroborated the State’s contention that the substance in the defendant’s possession was marijuana and not legal hemp. The court found that the trial court’s decision to admit the evidence was supported by reason and was not an abuse of discretion (THE COURT OF APPEALS OF NORTH CAROLINA, 2023, p. 501).
This case illustrates the significant impact digital evidence extracted using Cellebrite’s tools can have on legal proceedings. It demonstrates how such evidence can establish key elements of a crime, such as knowledge and intent, and how courts increasingly accept digital forensic evidence as crucial in criminal prosecutions.
Challenges in Application
Despite its advanced capabilities, Cellebrite’s tools face application challenges. These include issues with device compatibility and evolving encryption technologies. Additionally, there are limitations in extracting data from specific apps like Snapchat, which use ephemeral messaging systems.
