A New Image for Your Email Address

John Graham-Cumming, author of Bayesian spam filter POPFile, points me to a neat tool he’s created which will turn an email address into an image that may spare you some spam from bots scouring web pages for email addresses: This site converts a text-based email address (such as me@example.com) and creates an image that can …

CAPTCHA Gets Useful

An excellent example of something that leverages a tool that already exists and makes it useful — CAPTCHA forms. AP writes from Pittsburgh: Researchers estimate that about 60 million of those nonsensical jumbles are solved everyday around the world, taking an average of about 10 seconds each to decipher and type in. Instead of wasting …

The Email Hole

Email is not something to get too upset about, until you lose one to downtime by your provider of choice. And then you realise that it is too important to be left to free services, or even a domain hoster. I use a hoster called Hostway, and they went spectacularly down last week. (This despite …

Keep a Blog, Get Fired

Here’s an interesting statistic, in the light of Scoble’s departure from Microsoft (no direct connection, I promise, but it does raise issues about whether corporates really like blogging): 7.1% of companies have fired an employee for violating blog or message board policies. According to email security company Proofpoint, whose survey you can download from here, …

From the Ashes of Blue Frog

The Blue Frog may be no more,  but the vigilantes are. Seems that despite the death of Blue Security in the face of a spammer’s wrath, the service has built an appetite for fighting back. Eric B. Parizo of SearchSecurity.com reports on a new independent group called Okopipi who intend “to pick up where Blue …

The Red-faced Blue Frog

What’s intriguing about this Blue Security/Blue Frog episode, where angry spammers attack the anti-spam company with a Distributed Denial of Service (DDoS) attack, which in turn directs traffic (unwittingly or wittingly, it’s not clear yet) and temporarily brings down blog hoster TypePad, is this: The guy behind Blue Security, Eran Reshef, is founder of Skybox, …

The Blue Frog vs PharmaMaster

I’ve been trying to make some sense of this recent drama involving Blue Security, an anti-spam registry that effectively tries to deter uncooperative spammers by overwhelming their servers, and recent outages at TypePad and LiveJournal apparently caused by a revenge attack by spammers on Blue Security. (Here’s some more information on Blue Security and the …

The Penguin Embraces the Frog

Blue Frog, the anti-spam ‘vigilante’ software that has courted some controversy, has introduced a Linux Version : This new offering will enable the 29 million Linux platform users to participate in the Blue Community and register in the company’s Do Not Intrude Registry to actively fight spam and safeguard personal and business e-mail accounts though …

The Blue Frog Claims Some Early Success

Blue Security, the anti-spam company I wrote about somewhat skeptically for WSJ.com (subscription only, I’m afraid) a few months back, are claiming initial success in their Do Not Intrude Registry. (Simply put, users sign up for the service and Blue Security threatens a kind of mass ‘visit’ to any spammer that continues to spam any …
