Earlier this month I spoke at a cybersecurity conference in Albany, N.Y. alongside Tony Sager, senior vice president and chief evangelist at the Center for Internet Security and a former bug hunter at the U.S. National Security Agency. We  talked at length about many issues, including supply chain security, and I asked Sager whether he’d heard anything about rumors that Supermicro — a high tech firm in San Jose, Calif. — had allegedly inserted hardware backdoors in technology sold to a number of American companies.

Microsoft this week released software updates to fix roughly 50 security problems with various versions of its Windows operating system and related software, including one flaw that is already being exploited and another for which exploit code is publicly available.

What do we do with a company that regularly pumps metric tons of virtual toxic sludge onto the Internet and yet refuses to clean up their act? If ever there were a technology giant that deserved to be named and shamed for polluting the Web, it is Xiongmai — a Chinese maker of electronic parts that power a huge percentage of cheap digital video recorders (DVRs) and Internet-connected security cameras.

From time to time, there emerge cybersecurity stories of such potential impact that they have the effect of making all other security concerns seem minuscule and trifling by comparison. Yesterday was one of those times. Bloomberg Businessweek on Thursday published a bombshell investigation alleging that Chinese cyber spies had used a U.S.-based tech firm to secretly embed tiny computer chips into electronic devices purchased and used by almost 30 different companies. There aren’t any corroborating accounts of this scoop so far, but it is both fascinating and terrifying to look at why threats to the global technology supply chain can be so difficult to detect, verify and counter.

A ridiculous number of companies are exposing some or all of their proprietary and customer data by putting it in the cloud without any kind of authentication needed to read, alter or destroy it. When cybercriminals are the first to discover these missteps, usually the outcome is a demand for money in return for the stolen data. But when these screw-ups are unearthed by security professionals seeking to make a name for themselves, the resulting publicity often can leave the breached organization wishing they’d instead been quietly extorted by anonymous crooks.
