OpenSSH Going Strong After 10 Years With Release of v5.3 249

An anonymous reader writes "OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0 implementation and includes sftp client and server support. It encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other attacks. Additionally, OpenSSH provides secure tunneling capabilities and several authentication methods, and supports all SSH protocol versions. Version 5.3 marks the 10th anniversary of the OpenSSH project."

Twitter Used To Control Botnet Machines 127

DikSeaCup writes "Arbor Network's Jose Nazario, an expert on botnets, discovered what looks to be the first reported case of hackers using Twitter to control botnets. 'Hackers have long used IRC chat rooms to control botnets, and have continually used clever technologies, such as peer-to-peer strategies, to counter efforts to track, disrupt and sometimes decapitate the bots. Perhaps what's surprising then is that it's taken so long for hackers to take Twitter to the dark side.' The next step, of course, is to code the tweets in such a way that they aren't so suspicious."

Why Should I Trust My Network Administrator? 730

Andrew writes "I'm a manager at a startup, and decided recently to outsource to an outside IT firm to set up a network domain and file server. Trouble is, they (and all other IT companies we could find) insist on administering it all remotely. They now obviously have full access to all our data and PCs, and I'm concerned they could steal all our intellectual property, source code and customers. Am I being overly paranoid and resistant to change? Should we just trust our administrator because they have a reputation to uphold? Or should we lock them out and make them administer the network in person so we can stand behind and watch them?"

Local Privilege Escalation On All Linux Kernels 595

QuesarVII writes "Tavis Ormandy and Julien Tinnes have discovered a severe security flaw in all 2.4 and 2.6 kernels since 2001 on all architectures. 'Since it leads to the kernel executing code at NULL, the vulnerability is as trivial as it can get to exploit: an attacker can just put code in the first page that will get executed with kernel privileges.'"

Yahoo Revives Pay-Per-Email, With Charitable Twist 287

holy_calamity writes "Yahoo research have started a private beta of a scheme that resurrects the idea of charging people to send email to cut spam. Centmail users pay $0.01 for each message they send, with the money going to a charity of their choice. The hope is that the feel good effect of donating to charity will reduce the perceived cost of paying for mail and encourage mass adoption, making it possible for mail filters to build in recognition of Centmail stamps."
