Yesterday we wrote about toxic e-waste being dumped into landfills around poor communities in Asia and Africa where scavengers, including children, earn a pittance reclaiming and selling metals and other materials, materials loaded with chemicals that poison the air, water, land – and people.

But there is more in that discarded hardware than metal, plastic and wire. There is also information. In 2003 two MIT graduate students discovered credit card and Social Security numbers, medical records and other confidential information in computers that had been thrown away. “Even those with ‘erased’ disk drives may harbor confidential information,” their report revealed. The MIT News article goes on to say,

“Scavenging through the data inadvertently left on 158 used disk drives, the students at MIT’s Laboratory for Computer Science found more than 5,000 credit card numbers, detailed personal and corporate financial records, numerous medical records, gigabytes of personal email and pornography….Of the disk drives acquired, 129 were functional. Of these, Garfinkel and Shelat found 28 disk drives in which little or no attempt had been made to erase any information. One of these drives, Shelat says, had apparently come from an automatic teller machine in Illinois and contained a year’s worth of financial transactions.”

If you project the team’s findings to the tens of millions of computers tossed out every year (“More than 150 million disk drives were retired from primary service in 2002,” the report says) well, you don’t have to be an MIT graduate student to figure out just how big the problem is. Read
MIT researchers uncover mountains of private data on discarded computers and learn why even with care it’s far harder to sanitize a computer than you think.

Though the report was written in 2003, there is no evidence whatsoever that users are any more conscientious today than they were six years ago. Meanwhile, the river of e-junk flows ever wider and faster, and, to the toxicity of the metals and poisons in it, you can add countless gigabytes of unsecured information and precious data that are falling into the hands of criminals.
