How the Bible and YouTube are fueling the next frontier of password cracking Early last year, password security researcher Kevin Young was hitting a brick wall. Over the previous few weeks, he made steady progress decoding cryptographically protected password data leaked from the then-recent hack of intelligence firm Stratfor. But with about 60 percent of the more than 860,000 password hashes cracked, his attempts to decipher the remaining 40 percent were failing. The so-called dictionary attacks he mounted using lists of more than 20 million passwords culled from previous website hacks had worked well. Augmented with programming rules that substituted letters for numbers or combined two or more words in his lists, his attacks revealed Stratfor passwords such as "pinkyandthebrain," "pithecanthropus," and "moonlightshadow."

7 Apps for Teaching Children Coding Skills It's hard to imagine a single career that doesn't have a need for someone who can code. Everything that "just works" has some type of code that makes it run. Coding (a.k.a. programming) is all around us. That's why all the cool kids are coding . . . or should be. Critical crypto bug in OpenSSL opens two-thirds of the Web to eavesdropping For a more detailed analysis of this catastrophic bug, see this update, which went live about 18 hours after Ars published this initial post. 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. The warning about the bug in OpenSSL coincided with the release of version 1.0.1g of the open-source program, which is the default cryptographic library used in the Apache and nginx Web server applications, as well as a wide variety of operating systems and e-mail and instant-messaging clients. The bug, which has resided in production versions of OpenSSL for more than two years, could make it possible for people to recover the private encryption key at the heart of the digital certificates used to authenticate Internet servers and to encrypt data traveling between them and end users.
