SENF Finds Credit Card Numbers, SSNs on Your PC

Like most security tools, SENF (Sensitive Number Finder) seems very useful not only for those wishing to up the ante on their personal security and for security experts, but for hackers as well. From Lifehacker:

"Free, open source application Sensitive Number Finder (Senf) scans your hard drive for personally identifying data worth stealing, like Social Security and credit card numbers. The software points out these vulnerable digits so you can remove or encrypt them to keep your personal finances or identity safe."
