Caution! FREAK Vulnerabilities in OpenSSL and SecureTransport

FREAK out; Security researchers warn of new vulnerabilities in Apple's OpenSSL and SecureTransport that allow an attacker to decrypt your login cookies and other sensitive information from HTTPS connections if you are using a vulnerable browser such as Safari.freak encryption key

Apple's SecureTransport is a library used by iOS and OS X applications, such as Safari for iPhone, iPad, and Mac. The OpenSSL protocol is open source, and is used by Android browsers, and many more.

With the OpenSSL and SecureTransport protocols, encryption is made in connections to banks, webmail, and other HTTPS webpages.

"The connection is vulnerable if the server accepts RSA_EXPORT encryption and the client either offers an RSA_EXPORT suite or uses an OpenSSL version that is vulnerable to CVE-2015-0204 vulnerabilities," according to, a website that explains the flaw. security.

"Vulnerable clients have many Google and Apple devices that use unpatched OpenSSL, a large number of embedded systems, and many other software products that use TLS."

How did this happen?

In the early 1990s, the US government banned the sale of software overseas unless the code used by the so-called "encryption export suites" containing encryption keys was no longer 512 bits.

At that time, in order to ensure Uncle Sam, only relatively weak encryption was exported to the rest of the world, and he held the strongest for himself.

However, the limitations on cryptos exports no longer apply, but some implementations of TLS and SSL protocols continue to support these 1990 technology for the export of encryption code.

This last defect, which we report today and was named FREAK (Factoring RSA Export Keys), can be exploited during the creation of a secure connection when encryption has not yet started.

Vulnerable clients (such as a web browser, smartphone or internet-of-things) start talking on a server (like the machine behind an HTTPS webpage), and listing the encryption algorithms and key lengths supported.

An intruder can monitor traffic between the client and the server and can intervene by saying that the client only receives encryption-encryption keys, such as telling one of the old 512-bit RSA keys.

Because of the flaw in OpenSSL and SecureTransport, the server responds with a weak key, the client accepts it and the encryption process begins.

Hopefully they will release patches immediately.
