tip of the data loss iceberg: worms == automated large scale intrusions
Recently there have been a spate of incidents in which U.S. federal government agencies reported data theft or loss, particularly data which could result in identity theft. The losses include the contact information and social security numbers of, literally, millions of federal employees and contractors. Most of these recent incidents were the result of stolen laptop hardware, USB Key fobs, or other computer hardware, although at least two involved unspecified intrusions (electronic theft of the data following a break-in to an online system). In the past several months, as the reports of stolen servers, hard drives, laptops, and USB key fobs have mounted, I've only seen two disclosed instance of an intrusion (in one case apparently targeted) which resulted in the theft of identity data concerning 1,502 people at the Department of Energy: Energy ups security efforts after loss of employee data and 26,000 people at the Department of Agriculture: U.S. Department of Agriculture hacked. Despite the sparse reports of such intrusions, we know that government PC systems are not uniquely protected from these threats. Although it hasn't been reported, there is ample reason to believe that significant data loss has also occurred over the past several years through worm, botnet, spyware, trojan and rootkit infestations. Such malware routinely scans the infected PC and mounted network drives or shares and uploads files and data into the arms of organized crime. This type of loss is harder for organizations to detect and remains underreported as a result. However, it has has undoubtedly resulted in many more exposures of similar magnitude than have theft of laptops. Many tens of thousands of computers in government agencies are infected with worms, bots, adware, spyware, viruses, trojans, and rootkits every year. The infection rates of many government agencies are not radically different from private industry. Why do we see so few reports about data loss from these types of large scale intrusions? The difference is that when a laptop is stolen, a bit of government-owned equipment goes missing. This produces a few unique circumstances that malware infections don't produce. Missing hardware:
