![]() ![]() The vulnerability was that the user-supplied phone number was validated by one component using previously registered numbers, and the following phone number was sent to another component that sanitized it before using it for validation purposes. Checkmarx's security experts discovered a technique to circumvent this process by using a catch-all email account with a private domain or any temporary e-mail provider and exploiting a flaw in the phone number verification process.Īttackers will intercept and alter the OpenAI API request in order to circumvent phone number limits, enabling them to submit several variations of the same phone number and yet qualify for the free credit for numerous accounts. ![]() Currently, phone manufacturers and carriers are working on a firmware update that will be sent out to users.Researchers from Checkmarx discovered a flaw in OpenAI's account validation process that lets any user receive an endless amount of free credit from the company by enrolling for services an unlimited number of times using the same phone number.ĭuring the account creation process, OpenAI employs an email and phone number validation mechanism, in which an email address is provided and validated via an activation link, and a validation code is delivered via SMS for phone numbers. Google has already sent out a generic code fix for Fake ID. This could lead to malicious apps accessing data and executing actions on other apps. However, all devices that are running on anything older than Android 4.4 Kitkat are still vulnerable to malicious apps that insert Trojan horse code into other apps. Google was alerted to the bug and released a patch last April. Forristal said that Fake ID dates back to the launch of Android 2.1 in January 2010 and can be used on all Android devices that do not have the patch for Google bug 13678484. The vulnerability affects all Android phones. After that, attackers can sign an application with the malicious identity certificate and the forged certificate authority claim. ![]() According to Bluebox, the security hole allows hackers to create their own identity certificates then forge a claim it was issued through a certificate authority. This means that a web browser would trust any certificate issued by Verisign. Identity certificates are issued through certificate authorities such as Verisign. For example, the vulnerability can be used by malware to escape the normal application sandbox and take one or more malicious actions: insert a Trojan horse into an application by impersonating Adobe systems gain access to NFC financial and payment data by impersonating Google Wallet or take full management control of the entire device by impersonating 3LM," Jeff Forristal, Bluebox's Chief Technology Officer, said in a blog post.įake ID works by exploiting Android's method of handling identity certificates, which verifies that an app is what it appears to be. This can result in a wide spectrum of consequences. "The vulnerability allows malicious applications to impersonate specially recognized trusted applications without any user notification. ![]()
