Thousands of law enforcement officials and people applying to be police officers in India have had their personal information leaked online—including fingerprints, facial scan images, signatures, and details of tattoos and scars on their bodies. If that wasn’t alarming enough, at around the same time, cybercriminals have started to advertise the sale of similar biometric police data from India on messaging app Telegram.
Last month, security researcher Jeremiah Fowler spotted the sensitive files on an exposed web server linked to ThoughtGreen Technologies, an IT development and outsourcing firm with offices in India, Australia, and the US. Within a total of almost 500 gigabytes of data spanning 1.6 million documents, dated from 2021 until when Fowler discovered them in early April, was a mine of sensitive personal information about teachers, railway workers, and law enforcement officials. Birth certificates, diplomas, education certificates, and job applications were all included.
Fowler, who shared his findings exclusively with WIRED, says within the heaps of information, the most concerning were those that appeared to be verification documents linked to Indian law enforcement or military personnel. While the misconfigured server has now been closed off, the incident highlights the risks of companies collecting and storing biometric data, such as fingerprints and facial images, and how they could be misused if the data is accidentally leaked.
“You can change your name, you can change your bank information, but you can't change your actual biometrics,” Fowler says. The researcher, who also published the findings on behalf of Website Planet, says this kind of data could be used by cybercriminals or fraudsters to target people in the future, a risk that’s increased for sensitive law enforcement positions.
Within the database Fowler examined were several mobile applications and installation files. One was titled “facial software installation,” and a separate folder contained 8 GB of facial data. Photographs of people’s faces included computer-generated rectangles that are often used for measuring the distance between points of the face in face recognition systems.
There were 284,535 documents labeled as Physical Efficiency Tests that related to police staff, Fowler says. Other files included job application forms for law enforcement officials, profile photos, and identification documents with details such as “mole at nose” and “cut on chin.” At least one image shows a person holding a document with a corresponding photo of them included on it. “The first thing I saw was thousands and thousands of fingerprints,” Fowler says.
Prateek Waghre, executive director of Indian digital rights organization Internet Freedom Foundation, says there is “vast” biometric data collection happening across India, but there are added security risks for people involved in law enforcement. “A lot of times, the verification that government employees or officers use also relies on biometric systems,” Waghre says. “If you have that potentially compromised, you are in a position for someone to be able to misuse and then gain access to information that they shouldn’t.”
It appears that some biometric information about law enforcement officials may already be shared online. Fowler says after the exposed database was closed down he also discovered a Telegram channel, containing a few hundred members, which was claiming to sell Indian police data, including of specific individuals. “The structure, the screenshots, and a couple of the folder names matched what I saw,” says Fowler, who for ethical reasons did not purchase the data being sold by the criminals so could not fully verify it was exactly the same data.

“We take data security very seriously, have taken immediate steps to secure the exposed data,” a member of ThoughtGreen Technologies wrote in an email to WIRED. “Due to the sensitivity of data, we cannot comment on specifics in an email. However, we can assure you that we are investigating this matter thoroughly to ensure such an incident does not occur again.”
In follow-up messages, the staff member said the company had “raised a complaint” with law enforcement in India about the incident, but did not specify which organization they had contacted. When shown a screenshot of the Telegram post claiming to sell Indian police biometric data, the ThoughtGreen Technologies staff member said it is “not our data.” Telegram did not respond to a request for comment.
Shivangi Narayan, an independent researcher in India, says the country’s data protection law needs to be made more robust, and companies and organizations need to take greater care with how they handle people’s data. “A lot of data is collected in India, but nobody's really bothered about how to store it properly,” Narayan says. Data breaches are happening so regularly that people have “lost that surprise shock factor,” Narayan says. In early May, one cybersecurity company said it had seen a face-recognition data breach connected to one Indian police force, including police and suspect information.
The issues are wider, though. As governments, companies, and other organizations around the world increasingly rely on collecting people’s biometric data for proving their identity or as part of surveillance technologies, there’s an increased risk of the information leaking online and being abused. In Australia, for instance, a recent face recognition leak impacting up to a million people led to a person being charged with blackmail.
“So many other countries are looking at biometric verification for identities, and all of that information has to be stored somewhere,” Fowler says. “If you farm it out to a third-party company, or a private company, you lose control of that data. When a data breach happens, you’re in deep shit, for lack of a better term.”
