Hackers are bypassing fingerprint scanners to steal your identity

Fingerprint sensors have been around for quite some time, and they’ve become a standard feature in most smartphones. Apple introduced Touch ID on the iPhone 5s in 2013. Since then, it has appeared on 12 major iPhone models (and some iPads as well).

Though Apple removed it from most phones after the iPhone 8, it’s still found in the iPhone SE series. On the flip side, almost every Android phone on the market has a fingerprint scanner. But are fingerprint scanners impossible to bypass? Frank from Deerton, Michigan, asked a similar question that I want to highlight and address because it helps all of us:

“Can a website be hacked/compromised with password and fingerprint protection (multiple verification)?”

I get what you’re saying, Frank. You’d think that since a fingerprint scanner literally requires your fingerprint, it couldn’t be bypassed. But you’d be wrong. While fingerprint scanners are generally more secure than facial recognition and passwords, they’re not foolproof. In fact, there are several ways bad actors can bypass them to steal your identity.

5 ways bad actors can bypass fingerprint scanners

There are multiple ways hackers use to bypass fingerprint scanners. Below, I will discuss five of the more prominent methods.

1. Masterprints and DeepMasterPrints

Hackers exploit the concept of “masterprints,” which are fingerprints engineered to match multiple individuals’ prints. Researchers at NYU Tandon developed “DeepMasterPrints” using machine learning to generate synthetic fingerprints that can deceive sensors by mimicking common fingerprint features. These artificial prints can match with a significant percentage of stored fingerprints, especially on devices with less stringent security settings.

2. Forged fingerprints using 3D printing

Another trick hackers use is making fake fingerprints. They can lift prints off things you’ve touched and then use stuff like fabric glue or even 3D printers to make molds. For example, researchers at Cisco Talos tried out a bunch of different ways to do this using 3D printing and tested them on phones like the iPhone 8 and Samsung S10; laptops like the Samsung Note 9, Lenovo Yoga and HP Pavilion X360; and even smart gadgets like padlocks.

On average, the fake fingerprints worked about 80% of the time. They were able to fool the sensors at least once. Interestingly, they couldn’t crack the biometric systems on Windows 10 devices, but they pointed out that doesn’t necessarily mean those are more secure. It just means this particular method didn’t work on them.

3. Brute force attacks via BrutePrint

Attackers have found a cheap way to break into smartphones by brute force fingerprint authentication. The method, called BrutePrint, lets attackers get around the usual limits that stop too many failed fingerprint attempts. It works by taking advantage of two previously unknown flaws in the fingerprint system. These flaws, named Cancel-After-Match-Fail (CAMF) and Match-After-Lock (MAL), exist because of weak protection for fingerprint data on a part of the hardware called the Serial Peripheral Interface (SPI).

Basically, BrutePrint uses a hardware-based man-in-the-middle attack to hijack fingerprint data. It sits between the fingerprint sensor and the phone’s secure area (called the Trusted Execution Environment) and tries as many fingerprint images as needed until it finds a match. The relieving part is that the attacker needs to have physical access to the phone for this method to work.

4. Side-channel attacks with PrintListener

PrintListener is a side-channel attack that captures the sound of a finger swiping on a screen to extract fingerprint features. It might sound like something out of a sci-fi movie, but researchers have already built a proof of concept. By analyzing the friction sounds, attackers can reconstruct fingerprint patterns, potentially enhancing the effectiveness of masterprint attacks.

5. Exploiting unsecured fingerprint data storage

Some devices store fingerprint data without adequate encryption. If attackers gain access to this unprotected data, they can replicate fingerprints to bypass authentication. For example, in 2024, a misconfigured server exposed nearly 500 GB of sensitive biometric data, including fingerprints, facial scans and personal details of law enforcement applicants.

TOP 20 APPS TRACKING YOU EVERY DAY

So, can you trust fingerprint scanners?

Fingerprint scanners make it easy and fairly secure to unlock your devices. Since everyone has unique fingerprints, you don’t need to remember complicated passwords. Just a quick touch and you are in. Most modern devices store your fingerprint data in secure parts of the system, and they use things like liveness detection to make sure someone is not trying to trick the scanner with a fake finger.

Still, no security method is perfect. Skilled attackers have found ways to get past fingerprint scanners using high-resolution photos or 3D-printed fingers or by taking advantage of flaws in how the scanner communicates with the rest of the device. The risk really depends on how well the scanner is designed and how much effort someone puts into breaking it. For most people, fingerprint authentication is quick, easy and secure enough. However, if you are dealing with very sensitive information, relying only on biometrics might not be the best idea.

10 SIMPLE STEPS TO IMPROVE YOUR SMARTPHONE’S SECURITY AND PRIVACY

6 ways to protect your fingerprint data

Safeguard your biometric identity with these essential security measures.

1. Choose trusted phone brands: If you’re buying a phone, stick with well-known brands like Apple, Samsung or Google. These companies take extra steps to protect your fingerprint data by storing it in secure areas of the phone that are harder to access. Cheaper or lesser-known brands may not have these protections, which makes it easier for attackers to steal your data.

2. Keep your phone updated: Phone updates are not just about new features. They fix security problems that hackers might use to break into your device. If your phone asks you to install an update, do it. Most phones also let you turn on automatic updates, so you don’t have to worry about remembering. Keeping your software updated is one of the easiest and most important ways to stay protected.

3. Use strong antivirus software: Install strong antivirus software to detect malware that could compromise biometric data storage. Strong antivirus software offers real-time threat detection, anti-phishing and privacy features to block unauthorized access to fingerprint data. The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe. Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices.

WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

4. Don’t rely only on your fingerprint: Using a fingerprint to unlock your phone is convenient, but it shouldn’t be your only line of defense, especially for sensitive apps like banking or email. Always set up a PIN, password or pattern as a backup on your iPhone and Android. This way, even if someone manages to copy your fingerprint, they still need another piece of information to get in.

5. Be careful about who handles your phone: If someone else uses your phone, especially a stranger or someone you don’t know well, they might be able to copy your fingerprint from the screen. It’s rare, but it happens. To reduce this risk, avoid handing your phone to people unnecessarily and wipe your screen occasionally to remove any clear fingerprints.

6. Only use fingerprint login with trusted apps: Not every app that asks for your fingerprint is trustworthy. It’s safest to use fingerprint login only with apps from known and reliable companies, like your bank, phone manufacturer or email provider. If an unfamiliar app asks for fingerprint access, it’s better to skip it and use your password instead.

7. Consider using a personal data removal service: Even fingerprint scanners can be bypassed, and large amounts of personal and biometric data have been exposed in breaches. Using a personal data removal service helps reduce your risk by removing your sensitive information from public databases and data broker sites, making it harder for hackers to piece together details that could be used to steal your identity. Check out my top picks for data removal services here.

WHAT HACKERS CAN LEARN ABOUT YOU FROM A DATA BROKER FILE

Kurt’s key takeaway

Passwords are generally easier to hack than biometric data like fingerprints or facial recognition. However, the key difference is that passwords can be changed if they’re compromised. Your biometrics cannot. Most modern devices allow both options, and biometrics can offer an extra layer of security by making it harder for someone else to access your phone or apps. They’re also fast and convenient, since you don’t need to remember or type anything. That said, in most cases, your device still falls back on a password or PIN when biometric identification doesn’t work, so both systems often go hand in hand.

Defense secretary Pete Hegseth designates Anthropic a supply chain risk

This week, Anthropic delivered a master class in arrogance and betrayal as well as a textbook case of how not to do business with the United States Government or the Pentagon.

Our position has never wavered and will never waver: the Department of War must have full, unrestricted access to Anthropic’s models for every LAWFUL purpose in defense of the Republic.

Instead, @AnthropicAI and its CEO @DarioAmodei, have chosen duplicity. Cloaked in the sanctimonious rhetoric of “effective altruism,” they have attempted to strong-arm the United States military into submission – a cowardly act of corporate virtue-signaling that places Silicon Valley ideology above American lives.

The Terms of Service of Anthropic’s defective altruism will never outweigh the safety, the readiness, or the lives of American troops on the battlefield.

Their true objective is unmistakable: to seize veto power over the operational decisions of the United States military. That is unacceptable.

As President Trump stated on Truth Social, the Commander-in-Chief and the American people alone will determine the destiny of our armed forces, not unelected tech executives.

Anthropic’s stance is fundamentally incompatible with American principles. Their relationship with the United States Armed Forces and the Federal Government has therefore been permanently altered.

In conjunction with the President’s directive for the Federal Government to cease all use of Anthropic’s technology, I am directing the Department of War to designate Anthropic a Supply-Chain Risk to National Security. Effective immediately, no contractor, supplier, or partner that does business with the United States military may conduct any commercial activity with Anthropic. Anthropic will continue to provide the Department of War its services for a period of no more than six months to allow for a seamless transition to a better and more patriotic service.

America’s warfighters will never be held hostage by the ideological whims of Big Tech. This decision is final.

What Trump’s ‘ratepayer protection pledge’ means for you

NEWYou can now listen to Fox News articles!

When you open a chatbot, stream a show or back up photos to the cloud, you are tapping into a vast network of data centers. These facilities power artificial intelligence, search engines and online services we use every day. Now there is a growing debate over who should pay for the electricity those data centers consume.

During President Trump’s State of the Union address this week, he introduced a new initiative called the “ratepayer protection pledge” to shift AI-driven electricity costs away from consumers. The core idea is simple.

Tech companies that run energy-intensive AI data centers should cover the cost of the extra electricity they require rather than passing those costs on to everyday customers through higher utility rates.

It sounds simple. The hard part is what happens next.

Why AI is driving a surge in electricity demand

AI systems require enormous computing power. That computing power requires enormous electricity. Today’s data centers can consume as much power as a small city. As AI tools expand across business, healthcare, finance and consumer apps, energy demand has risen sharply in certain regions.

Utilities have warned that the current grid in many parts of the country was not built for this level of concentrated demand. Upgrading substations, transmission lines and generation capacity costs money. Traditionally, those costs can influence rates paid by homes and small businesses. That is where the pledge comes in.

What the ratepayer protection pledge is designed to do

Under the ratepayer protection pledge, large technology companies would:

Cover the full cost of additional electricity tied to their data centers
Build their own on-site power generation to reduce strain on the public grid

Supporters say this approach separates residential energy costs from large-scale AI expansion. In other words, your household bill should not rise simply because a new AI data center opens nearby. So far, Anthropic is the clearest public backer. CyberGuy reached out to Anthropic for a comment on its role in the pledge. A company spokesperson referred us to a tweet from Anthropic Head of External Affairs Sarah Heck.

“American families shouldn’t pick up the tab for AI,” Heck wrote in a post on X. “In support of the White House ratepayer protection pledge, Anthropic has committed to covering 100% of electricity price increases that consumers face from our data centers.”

That makes Anthropic one of the first major AI companies to publicly state it will absorb consumer electricity price increases tied to its data center operations. Other major firms may be close behind. The White House reportedly plans to host Microsoft, Meta and Anthropic in early March to discuss formalizing a broader deal, though attendance and final terms have not been confirmed publicly.

Microsoft also expressed support for the initiative.

“The ratepayer protection pledge is an important step,” Brad Smith, Microsoft vice chair and president, said in a statement to CyberGuy. “We appreciate the administration’s work to ensure that data centers don’t contribute to higher electricity prices for consumers.”

Industry groups also point to companies such as Google and utilities including Duke Energy and Georgia Power as making consumer-focused commitments tied to data center growth. However, enforcement mechanisms and long-term regulatory details remain unclear.

How this could change the economics of AI

AI infrastructure is already one of the most expensive technology buildouts in history. Companies are investing billions in chips, servers and real estate. If firms must also finance dedicated power plants or pay premium rates for grid upgrades, the cost of running AI systems increases further. That could lead to:

Slower expansion in some markets
Greater investment in renewable energy and storage
More partnerships between tech firms and utilities

Energy strategy may become just as important as computing strategy. For consumers, this shift signals that electricity is now a central part of the AI conversation. AI is no longer only about software. It is also about infrastructure.

The bigger consumer tech picture

AI is becoming embedded in smartphones, search engines, office software and home devices. As adoption grows, so does the hidden infrastructure supporting it. Energy is now part of the conversation around everyday technology. Every AI-generated image, voice command or cloud backup depends on a power-hungry network of servers.

By asking companies to account more directly for their electricity use, policymakers are acknowledging a new reality. The digital world runs on very physical resources. For you, that shift could mean more transparency. It also raises new questions about sustainability, local impact and long-term costs.

What this means for you

If you are a homeowner or renter, the practical question is simple. Will this protect my electric bill? In theory, separating data center energy costs from residential rates could reduce the risk of price spikes tied to AI growth. If companies fund their own generation or grid upgrades, utilities may have less reason to spread those costs among all customers.

That said, utility pricing is complex. It depends on state regulators, long-term planning and local energy markets.

Here is what you can watch for in your area:

New data center construction announcements
Utility filings that mention large commercial load growth
Public service commission decisions on rate adjustments

Even if you rarely use AI tools, your community could feel the effects of a nearby data center. The pledge is intended to keep those large-scale power demands from showing up in your monthly bill.

Kurt’s key takeaways

The ratepayer protection pledge highlights an important turning point. AI is no longer only about innovation and speed. It is also about energy and accountability. If tech companies truly absorb the cost of their expanding power needs, households may avoid some of the financial strain tied to rapid AI growth. If not, utility bills could become an unexpected front line in the AI era.

Here’s your first look at Kratos in Amazon’s God of War show

Amazon has slowly been teasing out casting details for its live-action adaptation of God of War, and now we have our first look at the show. It’s a single image but a notable one showing protagonist Kratos and his son Atreus. The characters are played by Ryan Hurst and Callum Vinson, respectively, and they look relatively close to their video game counterparts.

There aren’t a lot of other details about the show just yet, but this is Amazon’s official description:

The God of War series storyline follows father and son Kratos and Atreus as they embark on a journey to spread the ashes of their wife and mother, Faye. Through their adventures, Kratos tries to teach his son to be a better god, while Atreus tries to teach his father how to be a better human.

That sounds a lot like the recent soft reboot of the franchise, which started with 2018’s God of War and continued through Ragnarök in 2022. For the Amazon series, Ronald D. Moore, best-known for his work on For All Mankind and Battlestar Galactica, will serve as showrunner. The rest of the cast includes: Mandy Patinkin (Odin), Ed Skrein (Baldur), Max Parker (Heimdall), Ólafur Darri Ólafsson (Thor), Teresa Palmer (Sif), Alastair Duncan (Mimir), Jeff Gulka (Sindri), and Danny Woodburn (Brok).

While production is underway on the God of War series, there’s no word on when it might start streaming.
