A few weeks ago, security experts discovered a new major security SSLTLS vulnerability, dubbed FREAK, that for more than a decade left users of Apple and Google devices vulnerable to hacking when they visited millions of legitimate and secure websites. The FREAK critical vulnerability CVE 2. Factoring Attack on RSA EXPORT Keys, could be exploited by an attacker to conduct man in the middle attacks on encrypted traffic when Internet users visited supposedly secured websites. By exploiting the FREAK flaw, an attacker can force clients to use older and weaker encryption, then he can crack the traffic protected with 5. Once hes decrypted the protected traffic, the attacker can steal sensitive information, including banking credentials, or launch an attack by injecting malicious code in the encrypted stream of data. The flaw resulted from a former U. S. government policy that forbade the export of strong encryption and required that weaker export grade products be shipped to customers in other countries, say the researchers who discovered the problem. These restrictions were lifted in the late 1. United States, apparently unnoticed until this year,states. The Washington Post on the FREAK vulnerability. Computer Forensics Training Resources Info. SecThe FREAK vulnerability was discovered by security researchers of the French Institute for Research in Computer Science and Automation Inria and Microsoft. It affects both Open. SSL versions 1. 0. Apples Secure Transport. In a classic attack scenario, the exploitation of a vulnerable device i. Android browsers, Open. SSL versions, Chrome versions before 4. Safari is possible if the user visits a vulnerable HTTPS protected website. The attack could be effective if the server hosting the website visited by victims is still supporting 1. RSA. Many experts have associated the FREAK and POODLE vulnerabilities due to the similarity in the way they exploit flaws in protocols to make vulnerable a connection deemed secure.

Visual Basic 6. 0 is no longer supported by Microsoft so how do you get a hold of it Currently there is not an easy legal way to get a hold of VB6. Excels automatic axis scaling often seems somewhat mysterious, and its not easy to find information about it. Microsoft has a couple articles in the MSDN. The POODLE vulnerability stands for Padding Oracle on Downgraded Legacy Encryption. It allows malicious attackers to lower the SSLTLS communication to the weakest possible version. FREAK is quite similar in the way it affects the SSLTLS implementations that supports and accepts export versions of protocols that use the RSA algorithm. The export grade encryption. Back in the 1. 99. US government endeavored to direct the export of items using robust encryption, and gadgets were stacked with weaker export grade encryption before being dispatched out of the country, which allowed a maximum key length of 5. The situation changed in 2. US export laws that authorized merchants to include 1. Figure 1 FREAK vulnerability The Washington PostThe experts that found the FREAK vulnerability discovered that the export grade cryptography support was never removed.

M attack exploiting the vulnerability. Professor Green detailed a Man In The Middle attack that exploits the FREAK flaw In the clients Hello message, client asks for a standard RSA cipher suite from the server. The Mit. M attacker hampers the integrity of this message and changes this message to ask for Export RSA. The server responds to the clients request with a 5. Project managers everywhere rely on Microsoft Office Project to plan and manage their projects. With Microsoft Office Project, efficiently organize and track. RSA key, signed with its long term key. The client accepts this weak key from the server due to the Open. SSL Secure Transport bug. The attacker factors the RSA modules to recover the corresponding RSA decryption key.

From here on out, the attacker sees plain text and can inject anything it wants. Figure 2 NSA Website vulnerable to the FREAK attack. The researchers Alex Halderman, Zakir Durumeric and David Adrian at University of Michigan made a large scale scan to identify vulnerable websites. The experts examined more than 1. SSLTLS protocols and discovered that the FREAK vulnerability affects nearly 3. SSL WEBSITES. Based on some recent scans by Alex Halderman, Zakir Durumeric and David Adrian at University of Michigan, it seems that export RSA is supported by as many as 5. The vast majority of these sites appear to be content distribution networks CDN like Akamai. Those CDNs are now in the process of removing export grade suites, states Matthew Green. Several security experts speculate that the FREAK vulnerability was intentionally introduced by governments in order to conduct surveillance activities. FREAK is a good example of what can go wrong when government asks to build weaknesses into security systems,wrote Ed Felten, another respected professor of computer science at Princeton University. All Windows systems are vulnerable to the FREAK attack. According to a security advisory published by Microsoft, all supported versions of Windows OS are affected by the recently discovered FREAK vulnerability. The impact of the vulnerability could be dramatic for Microsoft systems, as confirmed by the security advisory that informs its customers about the presence of the FREAK vulnerability in the Microsoft Secure Channel Schannel stack. Secure Channel, also known as. Schannel, is asecurity support providerSSP that contains a set of security protocols that provide identity authentication and secure, private communication through encryption. Schannel is primarily used for Internet applications that require secure Hypertext Transfer Protocol HTTP communications. Secure Channel is vulnerable to the FREAK encryption downgrade attack and affects all supported releases of Microsoft Windows. Microsoft is aware of a security feature bypass vulnerability in Secure Channel Schannel that affects all supported releases of Microsoft Windows. Our investigation has verified that the vulnerability could allow an attacker to force the downgrading of the cipher suites used in an SSLTLSconnection on a Windows client system. The vulnerability facilitates exploitation of the publicly disclosed FREAK technique, which is an industry wide issue that is not specific to Windows operating systems. When this security advisory was originally released, Microsoft had not received any information to indicate that this issue had been publicly used to attack customers. The Windows version affected by the FREAK vulnerability CVE 2. Windows Server 2. Windows Vista. Windows Server 2. Windows 7. Windows 8 and 8. Windows Server 2. Windows RTMicrosoft experts explained that hackers that share the same network of the victims could exploit the FREAK flaw and force the software using the Schannel component i. Internet Explorer to adopt weak encryption over the web. Microsoft confirmed that its experts are actively working to fix the issue and to protect its users from cyber attack exploiting the FREAK vulnerability. We are actively working with partners in our Microsoft Active Protections ProgramMAPP to provide information that they can use to provide broader protections to customers, continues the advisory. Google immediately released an updated version of the Chrome browser for Mac systems, meanwhile Safari on Mac OS and i. OS isnt vulnerable to the FREAK flaw. Researchers hack NSAs website with only 1.
