Check Point Response to CVE-2015-0204 - TLS FREAK Attack

Symptoms - On Tuesday, March 3, 2015, researchers disclosed a new SSL/TLS vulnerability - the FREAK attack. The vulnerability allows attackers to intercept HTTPS connections between vulnerable clients and vulnerable servers and force them to use the "export-grade" cryptography, which can then be...

SSL/TLS EXPORT_RSA <= 512-bit Cipher Suites Supported (FREAK)

The remote host supports EXPORTRSA cipher suites with keys less than or equal to 512 bits. An attacker can factor a 512-bit RSA modulus in a short amount of time. A man-in-the middle attacker may be able to downgrade the session to use EXPORTRSA cipher suites e.g. CVE-2015-0204. Thus, it is...

'FREAK' — New SSL/TLS Vulnerability Explained

Another new widespread and disastrous SSL/TLS vulnerability has been uncovered that for over a decade left Millions of users of Apple and Android devices vulnerable to man-in-the-middle attacks on encrypted traffic when they visited supposedly 'secured' websites, including the official websites o...
