Twee UK parenting website Mumsnet is the second high-profile organisation to claim it has fallen victim to the infamous Heartbleed OpenSSL vulnerability.
Four researchers working separately have demonstrated a server's private encryption key can be obtained using the Heartbleed bug, an attack thought possible but unconfirmed.
Below is what we thought as of 12:27pm UTC. To verify our belief we crowd sourced the investigation. It turns out we were wrong. While it takes effort, it is possible to extract private SSL keys. The challenge was solved by Software Engineer Fedor Indutny and Ilkka Mattila at NCSC-FI roughly 9 hours after the challenge was first published.
Basically, an attacker can grab 64K of memory from a server. The attack leaves no trace, and can be done multiple times to grab a different random 64K of memory. This means that anything in memory -- SSL private keys, user keys, anything -- is vulnerable. And you have to assume that it is all compromised. All of it.
No matter how hard you try to stay safe, some aspects of securing your online data are completely out of your hands. That fact was made painfully obvious on Monday, when the Internet got caught with its collective pants down thanks to a critical vulnerability affecting a fundamental tool for secure online communications.
Many of the websites you use at home and in the office are vulnerable to hacking, according to researchers who uncovered a security flaw in OpenSSL, the open-source software that is used to encrypt online communications. Websites and apps that encrypt data with a password likely use OpenSSL, and the cryptographic library is used to secure the servers that work with more than 66 percent of active websites on the Internet.
Researchers have discovered an extremely critical defect in the cryptographic software library an estimated two-thirds of Web servers use to identify themselves to end users and prevent the eavesdropping of passwords, banking credentials, and other sensitive data.
University researchers claim to have designed a 'nearly unbreakable' cryptography model based on the human respiratory system, which they say could make life tough for criminals and spying governments.
Bitcoin and other "crypto-currencies" have been touted by their followers as the money of the future. However, the last 12 months have shown the pluses and minuses of the technology.
Security provider RSA endowed its BSAFE cryptography toolkit with a second NSA-influenced random number generator (RNG) that's so weak it makes it easier for eavesdroppers to decrypt protected communications, Reuters reported Monday.
It's already possible to make some inferences about the appearance of crime suspects from their DNA alone, including their racial ancestry and some shades of hair colour. And in 2012, a team led by Manfred Kayser of Erasmus University Medical Center in Rotterdam, the Netherlands, identified five genetic variants with detectable effects on facial shape.
Raymond "Jerry" Roberts - one of the last of a top World War Two code-breaking team at Bletchley Park - has died, aged 93, following a short illness.
Few figures in the IT security landscape command the respect and admiration of so many people as does Bruce Schneier. The well-regarded expert recently changed jobs, moving from BT to become the CTO of Co3 Systems in January of this year.
Hundreds of open source packages, including the Red Hat, Ubuntu, and Debian distributions of Linux, are susceptible to attacks that circumvent the most widely used technology to prevent eavesdropping on the Internet, thanks to an extremely critical vulnerability in a widely used cryptographic code library.
Bitcoin's value has dropped sharply after one of the largest trading exchanges said there was a flaw in the virtual currency's underlying software.
There has been a lot of news about Belgian cryptographer Jean-Jacques Quisquater having his computer hacked, and whether the NSA or GCHQ is to blame. There have been a lot of assumptions and hyperbole, mostly related to the GCHQ attack against the Belgian telecom operator Belgacom.
The indicted founder of digital currency Liberty Reserve says the U.S. government began targeting him only after he refused to turn over the source code for his proprietary system to the FBI.
A security startup founded by a former NSA bod has launched an encrypted email and privacy service, aimed initially at ordinary folks.
Yesterday afternoon, a woman seeking help with a decades-old family mystery posted a thread on Ask Metafilter titled "Decoding cancer-addled ramblings":
Underground cybercriminals are attempting to decrypt a 50GB dump of encrypted debit card PINs that security watchers reckon were lifted during last year's high profile breach against retail giant Target.
