Between 2020–2025 reporting and research identify several real-world efforts that either successfully deanonymized Tor hidden services or mounted credible deanonymization operations: (a) law‑enforceme...
Tor exit nodes are the point where encrypted Tor traffic re-enters the public Internet, creating both a privacy boundary and an exposure point: exit operators can see plaintext when the application-la...
Traffic-correlation (end‑to‑end correlation) remains a practical and active deanonymization technique against Tor in 2025 when an attacker can observe both the client‑side path into Tor and the exit‑s...
Traffic-correlation and timing-style deanonymization attacks against Tor are well-documented and can succeed under realistic conditions — particularly when an adversary can observe or control both end...
Reporting in 2024 shows multiple media and cybersecurity outlets saying German law enforcement surveilled Tor relays for months and used timing-analysis techniques to deanonymize at least one user—cla...
Reporting and expert review of German investigations into the “Boystown” takedown say law enforcement used timing (traffic) analysis via Tor-operated relays to deanonymize some Onion service operators...
Timing-analysis defenses such as Vanguards and recent Tor protocol and client updates materially raise the bar for deanonymization — they reduce success rates of many published timing and correlation ...
Since 2023, Tor’s raw relay capacity and software changes aimed at using that spare capacity (notably congestion control in Tor 0.4.7) have increased the network’s throughput and utilization, meaning ...
Between 2020 and 2025, network‑level research and operational incidents sharpened two linked threats to Tor hidden services: traffic‑correlation at the network/AS level, and fast guard‑discovery techn...
Traffic-correlation and global passive adversary (GPA) techniques can and have been used in research and real-world investigations to deanonymize Tor hidden services and clients under certain conditio...
Law enforcement and researchers have a toolkit of technical methods to deanonymize Tor users — the main categories are traffic/timing analysis, running malicious or numerous relays to control parts of...
