Global Surveillance Exposed: Ad-Tracking Tech Goes Rogue in Hands of Intelligence

A joint investigation by Bloomberg and Citizen Lab has exposed an ad-based surveillance system called Webloc, developed by Penlink, which is now being used by security agencies worldwide. The system tracks individuals across the internet by leveraging advertising technology, originally designed for targeted marketing, and repurposes it for mass surveillance. Researchers have identified customers across multiple continents, including the US, UK, Netherlands, Germany, Mexico, Singapore, Saudi Arabia, UAE, Israel, El Salvador, Hungary, and Austria.

The use of Webloc represents a significant escalation in government surveillance capabilities, allowing agencies to monitor citizens without traditional warrants or oversight. This technology "trickles down" from military and intelligence agencies to local police, creating a powerful tool that operates in legal gray areas, particularly in Europe where its lawfulness is hotly debated. The real-world impact is a dramatic erosion of digital privacy worldwide, with authoritarian regimes gaining particularly dangerous capabilities to track dissidents and ordinary citizens alike through their everyday online activities.
