How is it possible that someone can track your location anywhere in the world with just your phone number? While the apps on your phone are asking for GPS access, an older, invisible part of the global telecom infrastructure has quietly allowed such tracking for decades. This is SS7 (Signaling System No. 7).

Developed in the 1970s, SS7 was never designed with security in mind. Today, despite being perhaps outdated, it still underpins most global mobile communications. As a result, it has become a go-to tool for both legitimate intelligence work and unauthorized surveillance. In this article, we investigate SS7’s role in mobile phone geolocation, who uses it today, how it works, and what it means for privacy and corporate security in Europe and Asia.

Starting July 10, 2025, Instagram began allowing public content from professional accounts to be indexed by search engines like Google. This means that your photos, videos, Reels, and captions could now appear in search results, making your content discoverable beyond the Instagram platform.

What Does This Mean for You?

Previously, Instagram used technical measures to prevent search engines from indexing its content. However, as of July 10, professional accounts have the option to opt in to this indexing feature. This means that if you have a public professional account, your content may now appear in Google search results unless you choose to opt out.
