And unless or until we have examples of accounts emptied through the hack, it’s difficult to argue the point. PayPal didn’t dismiss the issue when I spoke with them, but told me it was a risk they believed was managed by their system.

We believe the patch for this issue should be pretty straightforward and we essentially want to take action.” “It really does put a huge risk on many people's accounts that don't have user-enabled 2FA,” CyberNews told me, “which is most PayPal users. I asked PayPal for the percentage of users with the genuine 2FA enabled, but that information is not available. “We still want to emphasize,” one of the team told me, “that these ‘double checks’ from PayPal’s side, whether this main security bypass, name change, or phone verification, were easily bypassed.”ĬyberNews also questions the extent to which the misunderstanding actually matters, suggesting that not many users have enabled the genuine 2FA, relying instead on the systems checks to look after account security. CyberNews seems to feel very strongly that the issues should be disclosed and patched, and the team seems very frustrated that they haven't been. Because the vulnerabilities found are clearly important in themselves, the confusion has obfuscated the debate. Now that we can agree to your definition of 2FA, we'd phrase it differently.”Īnd that’s the crux here.
We alerted last month that this double-check can currently be bypassed, rendering it ineffective to any hacker who gains a person’s email and password.”Īgain, CyberNews explained that this had been misunderstood, “this specific quote was a general one, in response to all the six vulnerabilities we discovered.

newspaper by one of the CyberNews team: “PayPal and other sites such as Amazon and banks use two-factor authentication, so if an important change is made to the account this is double-checked, for instance through a security code being texted to the user’s mobile phone. This wasn't helped by a quote given to a U.K. And we think that's where the confusion stemmed from.”
Since this security measure requires a separate device beyond the person's username and password, we used the term 2FA as a reference or similarity. CyberNews does not claim to have hacked this 2FA process.ĬyberNews accepts that the terminology in its report is confusing, telling me “by 2FA, we really meant the default security measure that PayPal's algorithm triggers when there's a suspicious login on an account.
This would prevent any attacker gaining access to an account without the user’s cellphone or authenticator app, rendering a back-end security check bypass useless. Paypal does have genuine two-factor authentication-you can see its set-up in the image below. And last year the FBI-somewhat controversially-warned that secondary authentication was being spoofed by attackers and only biometrics could be seen as attack-proof. There have been plenty of stories of the defeat of 2FA-SIM jacking and the high-profile hacks of celebrity Twitter accounts, for example. This is normally an SMS one-time code, but it can be a PIN number that’s separate from your password, or an authenticator app or even an external security key. Two-factor authentication means something very specific these days-it is a secondary identity check at the point of every login or every new login that is intended to be a user controlled identity confirmation over and above a username and password. Their 2FA, which is called ‘Authflow’ on PayPal, is normally triggered when a user logs into their account from a new device, location or IP address.” Unfortunately for CyberNews, they described this as “two-factor authentication,” saying the team “was able to bypass PayPal’s phone or email verification, which for ease of terminology we can call two-factor authentication (2FA). In essence, it would work with phished credentials just as well as with stolen ones, and it links back to that bypassing of the system checks at the login point of the process. Essentially, they claim to have intercepted the backend data from the login process to prevent the backend system challenging the login attempt. CyberNews claims-and the company showed me a demonstration-that it can successfully login to an account using basic credentials on a new computer.
