Skype said Tuesday it is investigating a new tool that collects a person's last known IP address, a potential privacy-compromising issue.
Instructions posted on Pastebin on Thursday showed how a person's IP address could be shown without adding the targeted user as a contact by looking at the person's general information and log files.
Skype, which is owned by Microsoft, said in an e-mail statement that "this is an ongoing, industry-wide issue faced by all peer-to-peer software companies. We are committed to the safety and security of our customers and we are taking measures to help protect them." In October, Skype acknowledged a research paper that showed how a Skype user's IP address can be determined without that user knowing. It also demonstrated that more than half the time the IP address could be accurately linked to sharing content using the BitTorrent file-sharing protocol.
