Spammers' Backlash
On May 1, 2006, Blue Frog members started to receive intimidating e-mail messages from sources claiming that the software was actually collecting personal details for identity theft, DDoS attacks, creating a spam database, and other such purposes. Blue Security has dismissed these claims.
One variant of the e-mailed message stated that spammers had found a way to extract addresses from the database for malicious purposes. Due to how the Blue Security software works, this is not possible; however, spammers can identify BlueFrog member e-mail addresses in lists they already possess. Blue Security provides spammers a free tool that allows them to "clean their lists". Extracting addresses directly from the program would be impossible as they are just hashes, but a spammer can run a list through the BlueSecurity filter and then compare the results with an unaltered list, and thus identify BlueSecurity users and target them. This method can only identify Blue Frog addresses already in the spammer's possession, and cannot give them access to as-yet untargeted addresses.
