FREAK vulnerability is a disastrous SSL/TLS flaw disclosed Mon that allows an aggressor to forcefulness SSL clients, including OpenSSL, to downgrade to weaken ciphers that tin hold upwardly easily broken too and thus supposedly acquit Man-in-the-Middle attacks on encrypted HTTPS-protected traffic passing betwixt vulnerable end-users too Millions of websites.

FREAK IN MICROSOFT RESIDES IN SECURE CHANNEL
Microsoft issued an advisory published Th alert Windows users that Secure Channel (Schannel) stack — the Windows implementation of SSL/TLS — is vulnerable to the FREAK encryption-downgrade attack, though it said it has non received whatever reports of populace attacks.
When the safety glitch kickoff discovered on Monday, it was believed that the Windows organisation was immune to FREAK attacks. But similar a shot if you're the i using Windows, attackers on your network could forcefulness the software using Schannel constituent such equally Internet Explorer to role weak encryption over the web.
"Microsoft is aware of a safety characteristic bypass vulnerability inwards Secure Channel (Schannel) that affects all supported releases of Microsoft Windows," the society said inwards a security advisory. "The vulnerability facilitates exploitation of the publicly disclosed FREAK technique, which is an industry-wide number that is non specific to Windows operating systems."
FREAK ENCRYPTION-DOWNGRADE ATTACK
FREAK — curt for Factoring assail on RSA-EXPORT Keys — made it significantly easier for hackers too cyber criminals to easily decode intercepted HTTPS connections, revealing sensitive data such equally login passwords, login cookies, too fifty-fifty banking information.
However, this is solely possible if the website or service at the other destination is withal supporting 1990s-era "export-grade" cryptography or 512-bit RSA, which were approved past times the U.S. authorities for overseas export. It was assumed that most servers no longer supported weak 512-bit RSA keys, but unfortunately, Millions of websites too services are withal available on the Internet using them.
AFFECTED WINDOWS VERSIONS
The FREAK vulnerability (CVE-2015-1637) inwards Windows Secure Channel constituent dramatically increases the number of users previously known to hold upwardly vulnerable. Affected versions of Windows include:
- Windows Server 2003
- Windows Vista
- Windows Server 2008
- Windows 7
- Windows viii too 8.1
- Windows Server 2012
- Windows RT
MICROSOFT WORKING ON PATCH
Microsoft said it is "actively working" amongst its Microsoft Active Protections Program partners to protect its users from FREAK, too i time the investigation larn over, it would "take the appropriate activeness to assist protect customers."
So, Windows users tin either await an out-of-band spell or a safety bulletin released on a regular Patch Tuesday.
MORE THAN 36% WEBSITES VULNERABLE
In recent weeks, safety researchers scanned to a greater extent than than xiv meg websites that back upwardly the SSL/TLS protocols too constitute that to a greater extent than than 36 percentage of them were vulnerable to the decryption attacks that back upwardly RSA export zip suites.
Yesterday, Google developers released an updated version of Chrome for Mac that can't hold upwardly forced past times attackers to role the older, weaker 512-bit RSA cipher, effectively patching the FREAK vulnerability.
At the fourth dimension of writing, the listing of affected spider web browsers included Internet Explorer, Chrome on Android, the stock Android browser, Safari on Mac OS too iOS, BlackBerry browser, Opera on Mac OS X too Opera on Linux. Users tin catch freakattack.com to decide their browser exposure.
