F-Secure's April Fools Hack Article is No Joke

April 01, 2011 Added by:Headlines

F-Secure posted a nice April Fool's day article that was so subtle it slipped into several security news feeds unnoticed. While the article itself may be just a fun prank, readers would be wise not to let the sardonic wit overshadow the important message about password security...

March 23, 2011 Added by:Ted LeRoy

The crackers are using automated tools that scan for valid ssh logins using a username list. The sites and names that come up can be processed again, checking for weak passwords or brute force vulnerabilities. The tools and method are not new, but the number of attacks seems much higher lately...

Insider Threats and Data Theft

March 21, 2011 Added by:Danny Lieberman

Network DLP is a poor security countermeasure against the WikiLeaks class of data breach. Network DLP can network-intercept but not analyze obfuscated data and is blind to removable media and smart phones. The best technical countermeasure against a leak must be at the point of data use...

RSA Fail - Security Lessons Unlearned

March 18, 2011 Added by:J. Oquendo

Security pros have to wonder about the security state as a whole when the founders of "two factor" key fobs take a hit. One would believe that in the event someone compromised a machine inside of RSA, their own security - two factor key fobs - would have prevented escalation between other machines...

HBGary Federal Security Fail... Again

March 17, 2011 Added by:J. Oquendo

IP based authentication is somewhat helpful, but can be hurtful. While an administrator can define who can and cannot visit locations, servers, pages, this can become a cumbersome process. It also does little against a potential client side attack where an attacker accesses a trusted machine...

Faking It - When is Two Factor Authentication Not?

February 28, 2011 Added by:Rafal Los

Take a look at the authentication scheme from a 360-degree view and see if the strong authentication 2-factor provides extends to all platforms (mobile device? HTML-only?) If not, then your account is protected by the lowest common denominator, for most sites that's a simple username and password...

Brute Forcing Passwords and Word List Resources

February 20, 2011 Added by:Rob Fuller

Brute force, even though it's gotten so fast, is still a long way away from cracking long complex passwords. That's were word lists come in handy. It's usually the crackers first go-to solution, slam a word list against the hash, if that doesn't work, try rainbow tables..
