New tests to fool automated spammers

On the Internet, nobody knows you're a human--until you fill out a captcha.

Captchas are the puzzles on many Web sites that present a string of distorted letters and numbers. These are supposed to be easy for people to read and retype, but hard for computer software to figure out.

Most major Internet companies use captchas to keep the automated programs of spammers from infiltrating their sites.

There is only one problem. As online mischief makers design better ways to circumvent or defeat captchas, Web companies are responding by making the puzzles more challenging to solve--even for people.

Anti-spam sites weather DDoS assault

In reply to: NEWS - June 11, 2007

Prominent anti-spam services came under a sustained denial of service attack late last week. The assault targeted Spamhaus, Spam URI Realtime Blocklists (SURBL), and Realtime URI Blacklist (URIBL).

The URIBL (which, like SURBL - filters junk mail based on spam sites mentioned in their message bodies) website was rendered temporarily available by the assault between Wednesday and Friday. It used DDoS mitigation technology from Prolexic to restore services.

Thwarting a large-scale phishing attack
by Donna Buenaventura / June 11, 2007 5:04 AM PDT
In reply to: NEWS - June 11, 2007

In addition to targeting malware, we're interested in combating phishing, a social engineering attack where criminals attempt to lure unsuspecting web surfers into logging into a fake website that looks like a real website, such as eBay, E-gold or an online bank. Following a successful attack, phishers can steal money out of the victims' accounts or take their identities. To protect our users against phishing, we publish a blacklist of known phishing sites. This blacklist is the basis for the anti-phishing features in the latest versions of Firefox and Google Desktop. Although blacklists are necessarily a step behind as phishers move their phishing pages around, blacklists have proved to be reasonably effective.

Yahoo hacker uses story to find, exploit Yahoo Messenger bug
by Donna Buenaventura / June 11, 2007 3:45 PM PDT
In reply to: NEWS - June 11, 2007

Yahoo Inc was quick out of the gate and released a fix for the vulnerabilities last Friday, just two days after the flaws were publicly disclosed. The trouble is that Terrell Karlsten, a spokeswoman for Yahoo, apparently disclosed too much information about the bugs in an interview with InformationWeek.

And that information helped lead a hacker, who identifies himself only as "Danny," right to the flawed code.
