data privacy automation Every system admin has lived through the same Monday morning ritual. A queue of forty tickets, half of them password resets, permission errors, or disk space warnings that any experienced technician could resolve in under two minutes.

That promise is now being tested in production Linux environments. . Early results are reshaping how IT teams think about tier-1...

A few years ago, web defacements were largely limited to individual sites, conducted by small groups of security enthusiasts with a bone to pick. Whether it was a political message, a technical statement or an expression of love to a girlfriend, the cracking of websites had a certain allure to them that made even the medium-level enthusiast raise his or her eyebrows. Those days are gone. Today, large groups of loosely-affiliated people work to attack as many websites as possible - cracking hundreds of sites in a single action. Taking the fun out of it. Replacing a well-researched site "hack" with a McCrack. With actions that defy the mantra of exposing vulnerabilities in an ethical way, the burgeoning community known as `script kiddies' are contributing to their own downfall.

On January 30th 2003, hacker BugBear defaced Mitnick's website at DefensiveThinking: zone-h We at Zone-H dug a little bit and discovered how the site was defaced. The attacker simply took advantage from the fact that DefensiveThinking administrator forgot to set up the policies for Frontpage extensions. To deface Mitnick's site it was enough to go on your windows desktop, create a new webfolder and name it with The lack of security set to Frontpage allowed the attacker to view the entire DefensiveThinking websystem as a folder of the attacker windows computer. To deface the webpage it was enough to create an HTML file with the defacement message and drag&drop it into the newly created webfolder. As simple as told. This configuration mistake allowed the attacker to view, browse, read all the files in DefensiveThinking's web structure. When Mitnick, interrogated by friends at The Register stated: "The compromised computer is a public system on a network separate from production systems at Defensive Thinking. No customer information was released nor was in danger of being compromised", we really hope it went in that way. More on the Permissions Problems with FrontPage Extensions at .
