Flipper Zero: What is it? An explanation of “Multi-Tool” portable hacking

Flipper Zero

These days, wireless connectivity is essential to daily life. Different kinds and wavelengths of wireless signals are used by phones, bank cards, and Wi-Fi connectivity, among other devices, to perform their functions. Although breaking into these signals has always required a thorough understanding of cybersecurity, the Flipper Zero hacking tool’s release has completely changed the procedure.

Flipper Zero: What Is It?

Flipper Zero is a portable, handheld penetration testing tool designed for hackers of all ability levels. It retails for a modest $169. Even smaller than the average mobile device, its proportions are modest, yet its capabilities are extensive. Keyless entry systems, Internet of Things devices, garage openers, NFC and RFID cards, and other wireless devices may all have their signals detected and replicated by this device thanks to its collection of radios and sensors. It was the result of open-source projects, and during its 2020 Kickstarter campaign, it garnered a lot of support and funding.

Under the hood, a 32-bit Arm CPU with a 64 megahertz maximum speed powers the gadget. Even though this might not seem like a huge deal, the way this CPU works with so many analog and serial peripherals—and most importantly, a highly-tuned radio transceiver—makes all the difference.

Its emergence on TikTok, where it was included in several videos, is credited with its recent rise in popularity. Hackers have been observed humorously altering fuel prices at gas stations, activating the charging connections of unidentified Tesla vehicles, and artistically modifying electronic menus. It’s important to remember, though, that these movies can overstate Flipper Zero’s powers a little bit. Many of these demonstrations may have been planned with a great deal of behind-the-scenes cooperation.

Using a Flipper Zero: A Guide

All users have to do is place the Flipper Zero near the source of a signal, choose the relevant application, and activate the “Read” feature. After being saved, these signals can be repeated whenever it’s convenient. It is important to remember, nevertheless, that although bank card NFC signals are detectable, their replication is limited.

A long blog article devoted to the Flipper Zero’s functioning and functionality could be necessary to cover it all. Thankfully, there are many of insightful posts about the Flipper Zero’s navigation available on the official Flipper site. The Flipper Zero documentation is an extensive resource for comprehending the complexities of the gadget. In addition, a number of internet discussion boards and forums, such as Reddit, have whole sections devoted to comprehensive instructions and professional community advice on how to use the Flipper Zero.

What Is the Price of Flipper Zero?

With a starting price of $169, Flipper Zero may be used with any microSD card that is formatted in FAT32; however, the card is not included in the package and is not required. Other Flipper Zero accessories include $15 for a protective silicone shell, $7.50 for a screen shield, $29 for a Wi-Fi development module, and $10 for prototype boards. One order on the official Flipper Zero website may include up to:

  • Two Flippers
  • Three cases made of silicone
  • Three Devboards with WiFi
  • Five Screen Shields
  • Five Drawing Boards

Where to Purchase Flipper Zero?

The Flipper Zero is available on its official US website for less than $200. Some resellers market it on other websites, such as Etsy and eBay, if it is sold out. Purchasing from unapproved vendors, however, may come with additional costs and hazards. Notably, after classifying it as a card-skimming device, Amazon stopped its sale. In the event that you are unable to obtain one, several Flipper Zero substitutes are becoming available in the industry.

How Can a Flipper Zero Be Used?

The Flipper Zero impresses right away with a variety of features. Its ability to scan different RFID cards simply putting them up to the Flipper is perhaps its most noteworthy feature. The Flipper may duplicate these cards since the data is stored to its SD card once it has been read. But there are also security issues to be concerned about with this feature. Cloning hotel key cards has even proven successful for certain Flipper Zero users.

The Flipper Zero is incredibly versatile because to its integrated infrared module, which can operate anything from air conditioners to TVs (you can find hundreds of hilarious videos on YouTube showing Flippers operating TVs in strange ways in places like workplaces and schools). It can also test the operation of infrared remote controls.

Moreover, radio remotes and iButton key fobs that use the 433-MHz frequency may be copied using the Flipper. It can recognize signals from contactless credit card chips and scan near-field communication (NFC) devices like MIFARE key cards. Replicating the latter’s distinct transaction codes is still difficult, though.

A common question is “Can Flipper Zero hack Wi-Fi?” Additional boards, like as a Wi-Fi board, can be added to the Flipper to improve its usefulness. Wi-Fi is added with a $45 board, mostly to help with updates. However, users may manage Wi-Fi signals more precisely by making simple adjustments to the Flipper and its Wi-Fi board. This includes sending out deauthorization messages to access points and initiating Wi-Fi network assaults. The Flipper may generate a variety of test signals for hardware troubleshooting, such as PWM testing of servos.

Additionally, the Flipper Zero can simulate USB mice and keyboards. It is a goldmine for automation lovers but also a possible security issue because it can run scripts to administer a graphical user interface. As a UART-to-USB bridge, it can also connect to devices that don’t support USB. Its sub-GHz antenna effectively picks up automobile key fob signals, but because most current vehicles have “rolling codes” installed, repeating the signals is frequently pointless.

Unbelievably, the Flipper Zero is able to circumvent certain Sentry Safe electronic safes. It was recently shown by YouTuber Peter Fairlie just how limited the Flipper Zero’s capacity to alter traffic signals is!

The Flipper Zero is also capable of the following extra tasks:

  • Gather information from a car’s tire pressure gauge.
  • Use the dog’s microchip to find out its body temperature.
  • Record and reproduce a garage door opener’s signal.
  • Identify the frequencies and face recognition signals that iPhones transmit.

Flipper Zero: Is It Legal?

It is legal to possess and use a Flipper Zero in the United States. Flipper Zero said on social media that U.S. Customs and Border Patrol confiscated a batch of their items in September 2022, but no more reports of comparable events have been made subsequently.

But keep in mind that, like owning a gun or lockpick set, it all depends on how you use it. Always check local legislation, and if in doubt, get legal advice. Generally speaking, you are safe if you are using the Flipper for personal belongings and electronics. However, tampering with someone else’s property might result in legal issues. Based on its location, the firmware of the device protects against broadcasting on prohibited frequencies.

It’s interesting to note that although the Flipper Zero is legal in the US, shipments of the device have already been seized by Brazil’s National Telecommunications Agency due to its illegal usage.

Are Cars Unlockable with Flipper Zero?

It is widely acknowledged by security experts that unless a serious flaw is discovered, the Flipper Zero will never be able to both decipher the encryption scheme and record the rolling codes of automobile key fobs. Rolling codes, also known as hopping codes, were first introduced in the 1990s and increased the security of keyless entry systems including garage door openers and keyless automobile systems. In essence, a rolling code stops hackers from replaying a recorded communication in order to unlock a system by thwarting their attempts to gain unauthorized access each time.

However, there may be a way to take advantage of this with Flipper Zero. Suppose you try to remotely unlock your automobile, but it doesn’t work (either because the signal jammer interferes or you’re too far away). A Flipper close by could pick up the signal even if the automobile doesn’t. When it gets close to the automobile, it may then reproduce that signal, which it has stored, to unlock it. The catch is that the Flipper’s stored code becomes invalid if the original fob transmits another signal before it can be replayed. Furthermore, unlocking the car with the Flipper may desynchronize your original key fob, locking you out and necessitating resyncing through dealerships or other key fobs.

If your car has rolling codes, make sure you physically or aurally confirm that the lock is locked. Though they are becoming less common, keep in mind that older cars without rolling codes are easy pickings for these repeat assaults.

Flipper’s Clever Manoeuvre Using Tesla’s Charging Ports

Experts in flippers discovered an oddity with Tesla charging port doors. Rolling codes are not used to operate the wirelessly operated doors on Tesla cars. As a result, it is simple for a Flipper Zero to intercept and repeat this signal, abruptly opening Tesla charging connections. Although the internal security of the automobile is unaffected, this joke is quite popular on social media sites like YouTube and TikTok.

The Rolling-PWN Vulnerability of Honda

Unexpectedly, it was discovered that certain Honda vehicles have a weak spot in its rolling code armor. This vulnerability, known as “Rolling-PWN,” allows attackers to use tools like Flipper Zero to intercept keyfob signals and use them to unlock or even start certain Honda vehicles.

Researchers Kevin2600 and Wesley Li discovered that when Honda’s system gets consecutive lock/unlock signals, it resynchronizes its codes. This implies that old codes that ought to have been thrown out might be accepted. In order to unlock and even start the Honda, a proficient attacker might thus intercept, save, and repeat these codes at a later time. However, leaving still presents a challenge because the real keyfob must be in close proximity.

Honda denied the weakness at first, then admitted it while stressing how complex the assault was and guaranteeing that the car could not be driven away. Honda also emphasized that it is still working to improve security in future models.

How to Guard Against Flipper Zero

With new hacking tools like the Flipper Zero appearing on the scene, it is critical that people and organizations take precautions to keep themselves safe. This is how you can defend yourself from these dangers:

Select RFID-Shielding Solutions: According to recent research, Flipper Zero’s capacity to intercept signals from your credit cards may be hindered by RFID-blocking wallets and cards.

Keep an Eye on Your Environment: When it comes to credit cards and access badges, Flipper Zero’s signal capturing range is somewhat limited. Pay attention to those who are close to you, especially in busy areas while waiting in lines. It might be important to keep your access badge hidden from possible scanners by not wearing it loosely around your waist.

Increase Badge Security by Using PINs Increase the security of your place of business by requiring a PIN in addition to access badges, akin to multi-factor authentication (MFA). The PIN is required for entry, even in the event that a Flipper copies the badge.

Mandate Badge Usage for Building Exit: Monitoring movements rather than stifling people is the goal. Using badges at entry, exit, and designated internal locations allows you to see all badge activity in one place. Anomalies like simultaneous badge usage at remote locations or duplicate admissions without an exit might be found with the aid of such visibility.

Accept Rolling Code Procedures Consider using rolling code techniques to strengthen signal security when developing a product or system that uses wireless signals, just like automakers and garage systems use.

Hire Ethical Hackers: Organizations may stay ahead of prospective adversaries by hiring penetration testers and ethical hackers to find weaknesses in their systems before actual assaults occur. Compass IT Compliance has been committed since 2010 to helping businesses identify the dangers associated with hacking tools like as the Flipper Zero, offering simple solutions to mitigate these risks, and making sure staff members are informed about new developments in the industry.
