Mobile spammers release DIY phone number harvesting tool

A new version of a well-known phone number harvesting tool is publicly released. Its main objective is to crawl the public web and index mobile phone numbers, which will later be used for various malicious and fraudulent purposes. Just like true marketers, the developer of the tool has included the option to choose a specific region within the available countries, with the idea of assisting in the inevitable malicious and fraudulent activity that will result from this phone number harvesting activity.

Takeaway: Always check whether the website that requires your phone number is actually listing it on its own website. Also, ensure that the website where you’re posting your phone number has some sort of protection against such automatic harvesting. Think beyond CAPTCHAs, as they are virtually irrelevant to today’s modern cyber criminals.
