Newly found online security flaw stems from 1990s By Afp Published: 22:57, 3 March 2015 | Updated: 22:57, 3 March 2015 e-mail 6 shares A newly discovered Internet security flaw could leave many websites vulnerable to hackers because of weak US encryption standards in the 1990s, researchers said Tuesday.The flaw dubbed “FREAK” could leave thousands of websites open to attacks if the problem is not patched, according to papers released by French and US researchers.The flaw was discovered by a team led by Karthikeyan Bhargavan at INRIA in Paris — the French Institute for Research in Computer Science and Automation — and disclosure coordinated by Matthew Green, a cryptographer at Johns Hopkins University.

But there is an important lesson here about the consequences of crypto policy decisions.”Green said Facebook’s site which operates the “like” button was identified as vulnerable but later patched.Green said the most of the flaws “will soon be patched” but that the flaw is important at a time when the NSA is seeking to maintain access to encrypted software and devices for national security reasons.”The moral of this story is pretty simple: Encryption backdoors will always turn around and bite you in the ass,” he wrote.
