Can you get hacked with YubiKey?
> A Yubikey can be hacked to send arbitrary keystrokes - but that's of limited usefulness.
Some platforms enable users to generate tokens in advance, sometimes providing a document with a certain number of codes that can be used in the future to bypass 2FA should the service fail. If an attacker obtains the user password and gains access to that document, they can bypass 2FA.
Yes! The YubiKey uses FIDO2 and PIV to offer phishing resistance at scale supported by all leading browsers and platforms, and hundreds of IAM and cloud services. One of the most highly recommended techniques by security experts for fighting phishing attacks, is a hardware security key.
Device Protections
By using secure elements within the YubiKey, both the Yubico software and hardware is protected in a way that makes it very difficult to tamper with.
Yubico, alongside Google (GOOG), helped create U2F, or Universal 2nd Factor, a security standard to let users access their accounts with a physical key, like Yubikey. Ehrensvard said Yubikey has protected journalists, students, and corporations from hackers.
Apps ask you to plug a tool like a YubiKey into your device and press a button. The YubiKey sends a unique code that the service can use to confirm your identity. This is more secure, because the codes are much longer, and more convenient, because you don't have to type out the codes yourself.
As you can see in the infographic below, adaptive authentication provides many advantages over standard 2FA. Adaptive authentication allows MFA to be deployed in a way that evaluates a user's risk profile and behaviors and adapts authentication requirements to different situations.
If your device with 2FA (two factor authentication) is lost broken or stolen, you should and most likely have to change your passwords, set up 2FA again, and get new verification codes.
Here's how hackers can steal the 2FA or OTP codes.
Once you enter it, the verification code reaches the hacker and they can now login to your account and perform sensitive transactions. The Vice in their report demonstrated one such instance where the user gets a call from PayPal's fraud prevention system.
FIDO2 is the umbrella term for a passwordless authentication open standard developed by the Fast Identity Online (FIDO) Alliance, an industry consortium comprised of technology firms and other service providers.
How does MFA prevent phishing?
In attacks where the attacker tries to trick a user into entering their credentials, certain types of MFA such as WebAuthn require the user to enter a yubikey or fingerprint from the system they're logging in from. These details cannot be captured by the attacker, thus protecting the system and user.
What Is a Scam Token? A scam token is a cryptocurrency that is launched for the express purpose of stealing investor funds. These are often developed on a pre-existing blockchain, such as Ethereum, as it's easier for a cybercriminal to do this instead of developing an entire blockchain.
But researchers have now shown that it is possible to clone keys -- given the key, a few hours, and thousands of dollars. Researchers from security firm NinjaLab have managed to make a clone of a Google Titan 2FA security key. The process makes use of a side-channel vulnerability in the NXP A700X chip.
Each function on the YubiKey can only accept and store data in the proper format for securely authenticating with the various supported validation protocols. All loaded information is stored in the secured EEPROM in the memory space allocated with the applications utilizing the data.
Some YubiKey tokens (like the YubiKey 5 Series) have both OTP (one-time password) and Security Key (including U2F) functionality. There are several differences between the two. Security Key: The USB device protects the user's private keys with a tamper-resistant component known as a secure element (SE).
Do I need to keep my yubikey plugged in all the time? A. No, you only need to insert your yubikey when you are prompted to do so during login. Leaving it plugged in could result in the yubikey being lost or damaged.
If you lose your Yubikey, you can still use your phone authenticator app, but you cannot create a backup Yubikey. However, Yubikey also provides methods to recover your account, so you can get a replacement. An advantage to Yubikey is that it comes on a USB that cannot be identified.
OATH (Yubico Authenticator) - the YubiKey 5's OATH application can hold up to 32 OATH-TOTP credentials (AKA authenticator app codes).
However, the YubiKey and device can see that even a phishing link or site with a valid SSL security certificate is bogus and will refuse to authenticate. Find out more about Yubico's malware protection here.
But in general yes: you can associate multiple keys to a single account.
What is the most secure YubiKey?
Buying Options. The best security key for most people is the Yubico Security Key, which comes in two forms: the Yubico Security Key NFC (USB-A) and the Yubico Security Key C NFC (USB-C).
U2F/WebAuthn Security Key
Experts believe that U2F/WebAuthn Security Keys are the most secure method of authentication. Security keys that support biometrics combine the Possession Factor (what you have) with the Inherence Factor (who you are) to create a very secure method of verifying user identities.
Another drawback of Google Authenticator that a reader pointed out is no passcode or biometric lock on the app. And this ease of access to the app seems to allow malware to steal 2FA codes directly from Google Authenticator, giving you yet another good reason to dump the app.
Hardware-based 2FA
Using a separate piece of hardware like an authenticator device or a U2F security key is the best way to secure any online account.
Once logged into the Android Lost website, select the phone to be managed in the upper right drop-down (above your email address) Click the the SMS tab (Figure B) Enter the 10 digit number (not the number of the phone being managed) to be allowed (under SMS Allowed) Click the Allow button.
What happens if I lose both my security key and my phone? You'll have a set of printed recovery codes, which you should store on paper in a safe place.
Use 2-Step Verification without your phone - YouTube
Google sends out six-digit codes to verify identities, and if a hacker gets ahold of it, they can take control of your account. There are several reasons why someone might partake in the Google voice code scam; many use other accounts to successfully place calls under a different persona, which leads to identity theft.
No matter what the story is, don't share your Google Voice verification code — or any verification code — with someone if you didn't contact them first. That's a scam, every time. Report it at ReportFraud.ftc.gov.
2FA can be vulnerable to several attacks from hackers because a user can accidentally approve access to a request issued by a hacker without acknowledging it. This is because the user may not receive push notifications by the app notifying them of what is being approved.
How secure is FIDO2?
FIDO2 cryptographic login credentials are unique across every website, never leave the user's device and are never stored on a server. This security model eliminates the risks of phishing, all forms of password theft and replay attacks.
FIDO2 officially launched in April 2018, and it was implemented in Google Chrome, Mozilla Firefox, and Microsoft Edge. In 2020, Safari on iOS, MacOS BigSur, and iPad OS 14 expanded support for FIDO2. In the past year, spending on multi-factor authentication (MFA) has risen.
Essentially, FIDO2 is the passwordless evolution of FIDO U2F. The overall objective for FIDO2 is to provide an extended set of functionality to cover additional use-cases, with the main driver being passwordless login flows.
Yes, by using free disposable numbers, you can bypass OTP verification. Without sharing your actual contact details, you can access any website or app.
For some reason, discord user tokens are plaintext, easy to steal, and let hackers bypass 2fa. Discord, your application is becoming a lawless wasteland of phishing and hackers.
Two-factor authentication adds an additional layer of security to the authentication process by making it harder for attackers to gain access to a person's devices or online accounts because, even if the victim's password is hacked, a password alone is not enough to pass the authentication check.
