The Significance of Mnemonic Phrases and Private Keys

Before delving into the advantages offered by EviSeed and EviVault, let’s first understand the significance of mnemonic phrases and private keys in cryptocurrency wallet security.

Understanding Mnemonic Phrases and Private Keys’ Role in Cryptocurrency Wallet Security

A mnemonic phrase consists of words used to generate and restore your private key, granting access to your cryptocurrency wallet and enabling transactions.Typically composed of 12, 18, or 24 words selected from a standardized list known as BIP39, a mnemonic phrase might look like:

apple, banana, lemon, orange, strawberry, kiwi, pineapple, mango, melon, watermelon, cherry, plum.

This mnemonic phrase is of utmost importance as it represents the sole means of recovering your cryptocurrency wallet in case of loss or theft of the storage device (e.g., smartphone, computer, USB key). Users must meticulously back it up and should never share it with anyone.

A private key, on the other hand, consists of a sequence of numbers and letters corresponding to the mnemonic phrase. It is employed for signing transactions and confirming ownership of the cryptocurrency wallet. A private key example is:

Securing Cryptocurrency Wallets

Now that we’ve examined the importance of mnemonic phrases and private keys, let’s discuss the risks associated with traditional backup methods and how EviSeed and EviVault technologies provide enhanced security solutions.

The Risks of Traditional Backup Methods for Mnemonic Phrases and Private Keys

Nevertheless, these methods have several drawbacks when it comes to cryptocurrency wallet security. Most cryptocurrency users choose to back up their mnemonic phrases and private keys using paper or metal media:

  • Impracticality: Manually writing or engraving mnemonic phrases and private keys can be tedious and prone to errors.
  • Inefficiency: Retrieving a cryptocurrency wallet or making transactions requires typing or memorizing the mnemonic phrase and private key, which can be time-consuming and cumbersome.
  • Lack of Durability: Paper and metal supports degrade over time, can be lost, damaged, or susceptible to environmental factors like fire, water, and physical harm.
  • Vulnerability: Physical and logical attacks are potential risks. For instance, if someone finds the support containing the mnemonic phrase and private key, they can access the cryptocurrency wallet and transfer funds to another address. If the support is connected to the internet, it can be infected with malware capable of stealing the mnemonic phrase and private key.

Why is Crypto Wallet Security Important?

Crypto wallet security involves protecting your crypto assets from unauthorized access, theft, or loss. Crypto wallet security involves two main components: your mnemonic phrase and your private key. Your mnemonic phrase is a sequence of words that is used to generate and restore your private key, which is the key that allows you to access your crypto wallet and make transactions. The mnemonic phrase and the private key are very important, because they are the only way to recover your crypto wallet in case of loss or theft of the support on which it is stored (smartphone, computer, USB key, etc.). You must therefore backup them carefully and never disclose them to anyone.

Crypto wallet security is important because cryptocurrencies are valuable and vulnerable to attacks. Hackers can exploit vulnerabilities in platforms storing and exchanging cryptocurrencies, employ phishing, malware, or social engineering to deceive users into disclosing their mnemonic phrases or private keys. If hackers get access to these keys, they can transfer the funds to their own addresses and make them untraceable. Therefore, you need to choose reliable and secure backup solutions for your mnemonic phrases and private keys, such as EviSeed and EviVault.

How Flipper Zero reads and emulates NFC cards

Flipper Zero has a Reading NFC cards function that allows it to read, save and emulate NFC cards. An NFC card is a transponder that operates at 13.56 MHz and has a unique number (UID) as well as a part of rewritable memory for storing data. Depending on the card type, memory can be segmented into sectors, pages, applications, etc. When near a reader, the NFC card transmits the requested data.

Flipper Zero can read different types of NFC cards according to their standard and protocol:

  • NFC cards type A: MIFARE Classic®, MIFARE Ultralight® & NTAG®, MIFARE® DESFire®
  • NFC cards type B: Calypso®, CEPAS
  • NFC cards type F: FeliCa™
  • NFC cards type V: ICODE® SLIX
  • Unknown cards: cards not recognized by Flipper Zero

Flipper Zero can also emulate NFC cards by using the data saved in its memory. To do this, you have to select a card from the Saved list then press Emulate. Flipper Zero will then behave like an NFC card and can communicate with a compatible reader.

Flipper Zero can therefore communicate with EviCore NFC HSM technology using the ISO 15693 standard which is supported by the ST25R3916 component it uses. However as we have seen previously this communication is limited and secured by EviVault NFC HSM protection mechanisms. Moreover Flipper Zero can emulate an ISO 15693 card even if the emulator has limitations. Indeed, the ST25R3916 component used by Flipper Zero allows emulation according to the ISO 15693 standard via RFLA (RF/NFC Abstraction Layer). However this emulation has limits to be able to test the NFC HSM of Freemindtronic. This excludes, for example, the possibility of testing the security and carrying out malicious attacks by emulating an ISO 15693 64Kb NFC chip used by the NFC HSMs used by the EviVault NFC HSM technology.

Flipper Zero’s Capabilities and Limitations in Attacking EviVault NFC HSM

Flipper Zero’s Support of NFC-V Protocol and Emulation

A New Feature in Firmware 0.85.2

Flipper Zero is a multifunctional gadget for hackers that supports NFC technology. It can read, write, clone, and emulate NFC cards using a built-in 13.56 MHz NFC module. Flipper Zero uses a ST25R3916 NFC controller and a RFAL library to handle high-frequency protocols (NFC) and facilitate the development of NFC applications.

Flipper Zero supports the NFC-V (ISO15693) protocol since the firmware version 0.85.2. This protocol is used by some NFC tags, such as transport cards or electronic labels. With this feature, Flipper Zero can read and emulate these tags, which can be useful for testing their security or having fun with them.

The NFC-V protocol is a contactless protocol that operates at 13.56 MHz and allows data transfer at a distance of a few centimeters, with a maximum speed of 26.48 kbit/s. The NFC-V protocol is based on the ISO15693 standard, which defines the physical and logical characteristics of NFC tags. The NFC-V tags are recognized by the NFC Forum as type 5 tags.

To use the NFC-V protocol with Flipper Zero, you need to select the “NFC” option in the main menu, then choose the “NFC-V” mode. Then you need to bring the Flipper Zero close to an NFC-V tag to detect it and display its information. You can then choose to perform different actions on the tag, such as:

  • Read: to read the content of the tag and display it on the screen of Flipper Zero. The tag can contain up to 256 blocks of 4 bytes each.
  • Write: to write data on the tag, by choosing the page and the bytes to modify. The writing can be protected by a password.
  • Clone: to copy the content of the tag into the internal memory of Flipper Zero. Flipper Zero can store up to 8 cloned tags.
  • Emulate: to make the reader believe that Flipper Zero is the original tag. Flipper Zero can emulate any cloned tag.

A Potential Threat for EviVault NFC HSM

This feature also introduces a potential threat for EviVault NFC HSM, as Flipper Zero can now emulate an NFC-V card and try to access its data or functions. However, this threat is not very serious, as EviVault NFC HSM has strong security mechanisms that prevent unauthorized access or tampering.

EviVault NFC HSM is a hardware security module that uses NFC technology to store and manage cryptographic keys. It is designed to protect sensitive data and transactions from unauthorized access or tampering. It can be used as a secure element for authentication, encryption, digital signature, or blockchain applications.

EviVault NFC HSM uses encryption, authentication, protection against cloning and replay, and other techniques to ensure that only authorized devices can interact with it. Even if Flipper Zero can emulate an NFC-V card, it cannot decrypt or modify its data, nor perform any cryptographic operations on it.

Therefore, Flipper Zero’s support of NFC-V emulation does not compromise EviVault NFC HSM’s security or confidentiality.

Flipper Zero’s Lack of Support for Energy Harvesting and Password Protection

Two Features of M24LR64E-R and ST25DV64KC Chips

The M24LR64E-R and ST25DV64KC are dynamic NFC/RFID chips with 64-Kbit EEPROM, energy harvesting, I2C bus and RF ISO 15693 interface. They are used by Freemindtronic for their EviVault NFC HSM products. They have two features that Flipper Zero does not support: energy harvesting and password protection.

Energy harvesting is a function that allows the chip to harvest energy from the RF field and use it to power external components. This can be useful for low-power applications or battery-less devices. The chip has an analog pin for energy harvesting and four sink current configurable ranges.

Password protection is a function that allows the chip to protect its data from unauthorized access or modification by using passwords. The chip has three 64-bit passwords in RF mode and one 64-bit password in I2C mode. The passwords can be used to protect one to four configurable areas of memory in read and/or write mode.

Two Limitations for Flipper Zero in Attacking EviVault NFC HSM

Flipper Zero cannot take advantage of these two features for several reasons:

  • Flipper Zero cannot emulate a tag NFC 15693 with a memory of 64-Kbit, because it does not have enough internal memory to store the content of the tag. It cannot therefore pretend to be the original tag and try to access its data or functions.
  • Flipper Zero cannot clone a tag NFC 15693 with a memory of 64-Kbit, because it does not have enough internal memory to copy the content of the tag. It cannot therefore create a duplicate of the tag and modify it at will.
  • Flipper Zero cannot write on a tag NFC 15693 protected by a password, because it does not know the password. It cannot therefore modify the data of the tag or make them inaccessible.
  • Flipper Zero cannot benefit from the energy harvesting function of the M24LR64E-R and ST25DV64KC chips, because it does not have an analog pin to harvest energy. It cannot therefore power external components with the energy of the tag.

These limitations further reduce Flipper Zero’s capabilities in attacking EviVault NFC HSM. While Flipper Zero can interact with NFC-V devices used by NFC HSM, it cannot emulate them, clone them, write on them. EviVault NFC HSM’s robust security mechanisms ensure that Flipper Zero cannot compromise its security or confidentiality.

In the next section, we will delve deeper into CryptBot and its inner workings

Malware Targeting Chrome Users: Understanding the Inner Workings of CryptBot

CryptBot is a type of malware that targets Chrome users by stealing their personal data, including cryptocurrency. But how does this malware infiltrate Chrome and avoid detection by antivirus software, and how does it communicate with its command server? Below is a brief technical explanation of CryptBot for those interested in the details:

  • CryptBot is primarily spread through phishing campaigns that offer a fake Chrome update or other legitimate software that contains a hidden virus. Once installed, the virus creates four files in the %TEMP% folder and activates a disguised BAT file that injects CryptBot into Chrome’s legitimate process. This allows the malware to access and encrypt the user’s data using the AES algorithm before sending it to its command server via an HTTP POST request.
  • In addition to stealing data, CryptBot can receive instructions from the command server via a JSON and AES-based communication protocol. These instructions can include downloading additional malware, updating the configuration settings, or deleting itself as needed.
  • Although CryptBot is a dangerous form of malware, understanding how it works can help users protect themselves from future attacks.

In conclusion, the threat CryptBot poses to the security of your data and cryptocurrencies on Chrome is real, but there are steps you can take to protect yourself. By following the advice we have shared and using Freemindtronic’s EviVault technology embedded in cold wallets such as Keepser, you can strengthen the security of your computer and protect your cryptographic assets from hackers.
