Operation Trojan Shield (known as Operation Ironside by Australian authorities) was a multi-year covert law enforcement operation in which the FBI, the Australian Federal Police, Europol, and partners in over a dozen countries distributed more than 12,000 purpose-built encrypted devices to criminal organizations worldwide. Unlike prior takedowns of encrypted communications providers such as Phantom Secure, Sky Global, and EncroChat, this operation involved the FBI covertly operating the platform itself, allowing investigators to receive a copy of every message sent by users for analysis.
The operation resulted in hundreds of arrests across Australia and Europe, the seizure of narcotics and criminal proceeds, and disruption of transnational organized crime networks involved in drug trafficking and violence. While not a traditional cyber-espionage or malware campaign, the story is notable from a threat-intelligence perspective as it illustrates law enforcement's evolving use of technical deception—running an entire encrypted communications platform as a honeypot—to defeat criminal reliance on hardened, encrypted devices.
This is fundamentally a law enforcement success story rather than a disclosure of an active cyber threat; there are no malware families, exploited vulnerabilities, or ongoing attacker TTPs relevant to network defenders. The primary significance is the erosion of trust in encrypted device ecosystems used by organized crime, and the signal that similar law enforcement operations may target other encrypted platforms in the future.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the campaigns it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
