The motivation for the attacks is also not known. It’s not yet known how the attack could go unnoticed for so long, and the two individuals were only arrested after a year-long investigation. The hackers had control of the central computer system and deleted a management application that caused the connection of the sensors to fail. The attacks took place between March and June last year and affected over 300 of the sensors. This network is used for monitoring unusually high levels of radiation and preparing against nuclear meltdown. The two employees, who have not been named, had worked on repairs and maintenance for Spain’s radioactivity alert system (RAR), which is a network of 800 detection sensors across the country. According to Gizmodo, Spanish police have arrested two former government contractors on charges of carrying out a large-scale cyber attack on the country’s gamma radiation detection sensors. Staff arrested for hacking nuclear radiation monitors.

As we advised in a previous news piece regarding the privacy risks of health apps, if you are concerned about how your data could be used, it might be best to record such data offline and avoid shopping on sites and apps known to track such data. It could potentially prevent pregnant people from accessing health care or cause them to delay appointments with doctors. There is understandable concern about how this information could be used. Gizmodo hypothesizes that one such company, AlikeAudience, may have been able to access the data of 61 million iOS users at a “Pregnancy & Maternity Life Stage” due to their relationship with MasterCard. However, Gizmodo found it impossible to figure out the precise source of many of the brokers’ data. Meanwhile, other companies developed algorithms to predict potentially pregnant users by analyzing their internal data.

Some companies found out people’s pregnancy status directly when they agreed to share their data to download a specific app or coupon. The data on offer has been gleaned in a multitude of ways. According to Gizmodo, the cost of datasets ranges from 49 cents to $2.25 per user reached. This means that anyone who buys access to the datasets only pays for the number of end-users their targeted ads reach. This information is being packaged to advertisers as datasets on a “cost per mille” (CPM) basis, also known as cost per thousand impressions. Many brokers are likely offering the same information. However, there is evidently some overlap with unique users, as 3.4 billion is far more than the US population and half the world’s population. The brokers are offering information on 3.4 billion people in total. Data privacy is in the spotlight once more as a number of data brokers across the US have been found promoting the sale of digital data relating to millions of pregnant and potentially pregnant people in the country.Īn investigation by Gizmodo revealed that 32 brokers offer unique mobile IDs for some 2.9 billion people’s profiles marked as “actively pregnant” or “shopping for maternity products.” Those interested can also access the data of customers who are “interested in pregnancy” or “intending to become pregnant,” as well as those who use certain types of birth control.
