This timeline examines claims connected to Cicada 3301 — the widely discussed online puzzle series — focusing on documented dates, source types, and turning points. It treats attribution and recruitment claims as claims (not established fact) and cites primary and high-trust reporting where available. The goal is to separate verifiable events (posts, signatures, physical clues) from disputed or unproven interpretations about who ran Cicada and why.
Cicada 3301 — Timeline: key dates and turning points
- January 4, 2012 — First public image posted on 4chan, containing the message “We are looking for highly intelligent individuals” that led solvers into a chain of steganography and cipher clues (primary source: archived 4chan post and contemporaneous reporting).
- January–February 2012 — Participants report a multi-stage puzzle using steganography, Caesar ciphers, and links that led to web pages and deeper clues; early solver reports and press coverage documented the puzzle flow and techniques used. (contemporaneous media and solver logs).
- January 4, 2013 — A second Cicada 3301 puzzle round appeared, again posted publicly and described as a renewed recruitment-style puzzle by researchers and reporters; the second round included references to obscure texts and technical challenges. (news reporting and community archives).
- 2012–2013 — Multiple puzzle clues led to physical locations worldwide (reports list coordinates and posters found in countries including Poland, Japan, and the United States); journalists and audio-visual evidence documented posters with QR codes and subsequent web leads. (radio and print journalism, solver photographs).
- January 4, 2014 — A third public clue appeared; reporting at the time and later retrospectives treated the 2014 activity as a continued public puzzle series with some rounds remaining unsolved. (press retrospectives and archives).
- January 5, 2016 — A Cicada-associated Twitter account posted an image that community investigators analyzed and some treated as an official clue; community-maintained archives captured the post and attempts to verify it. (social-media archive and community wiki).
- April 2017 — A message signed with a Cicada-associated OpenPGP key was published; reporting and archival notes indicate this signed message warned about false paths and emphasized verifying PGP signatures, and it has been treated by many researchers as the last verified signed communication. (Wikipedia summary and community archives referencing the PGP signed message).
- 2017–2024 — Ongoing community analysis, occasional new claims, and a mix of insider-style posts and longform investigations have kept the puzzle in public discussion; some investigative articles include interviews with former participants or people claiming insider knowledge, while mainstream reporting emphasizes the lack of authoritative attribution. (longform journalism and podcast retrospectives).
Where the timeline gets disputed
Even though many of the timeline events above are documented (posts, archived images, coordinated geographic clues, and signed OpenPGP messages), several major interpretive points remain disputed or unproven.
- Attribution: Multiple reputable summaries and journalist investigations note that no publicly verifiable, authoritative organization has claimed responsibility for running Cicada; claims that intelligence agencies, private companies, or specific networks operated it remain speculative and disputed.
- Recruitment purpose: The puzzles themselves state an intent to “find highly intelligent individuals,” and some community reporting describes people who reached closed darknet pages, but whether Cicada functioned as a formal recruitment program (and for whom) is not proven. Reporting records the claim but does not confirm downstream employment or formal onboarding.
- Insider and “warning” posts: Longform pieces and community threads report anonymous posts from people claiming to be “insiders” or former recruits; these accounts sometimes add specific organizational narratives, but they are not independently verifiable and conflict with alternative accounts that treat such posts as deliberate misinformation. Readers should treat these accounts as disputed claims unless corroborated by independent primary evidence.
- Scope and continuity: Some sources list multiple puzzle sets between 2012 and 2014 and intermittent signed messages afterward; community wikis and archives sometimes disagree on exact counts and which items are authenticated, producing differing timelines in secondary sources. Where sources conflict about counts or authentication, we indicate that disagreement rather than resolving it.

Evidence score (and what it means)
- Evidence score: 45 / 100.
- Documented primary items: multiple original public posts (4chan, Twitter), photographic evidence of posters and coordinates, and at least one PGP-signed message — these strengthen the timeline documentation.
- Gaps in attribution: No authoritative, independently verified organizational claim of responsibility or traceable legal entity is publicly documented; this lowers the score for claims about who ran Cicada.
- Conflicting/unverified insider material: Some longform reporting and community posts present insider-like narratives, but these are not corroborated with independent official documents, making them weak evidence for organizational claims.
- Community verification: Puzzle mechanics and many clue transits were reproducible by solvers and archived by community projects, which supports the factual timeline of puzzle activity even when interpretation differs.
Evidence score is not probability:
The score reflects how strong the documentation is, not how likely the claim is to be true.
FAQ
What is Cicada 3301 and when did it start?
Cicada 3301 refers to a series of public puzzles that began with a 4chan post on January 4, 2012, inviting solvers into layered cryptographic and steganographic challenges; this start date and the initial post are documented in contemporaneous reporting and archival records.
Did Cicada 3301 recruit for intelligence agencies?
That is a claim, not an established fact. Journalists and solvers have long speculated about links to intelligence services, but mainstream reporting notes there is no publicly verifiable evidence tying Cicada to a confirmed government recruitment program; available sources record the speculation and the lack of authoritative attribution.
What are the strongest primary sources for the timeline?
Primary sources for the documented timeline include archived public posts (e.g., the original 4chan image), community-captured photographs of physical posters and coordinates, and at least one OpenPGP-signed message that community archives and secondary reporting reference. These items form the backbone of the documented timeline even where interpretation varies.
Are there reliable insider accounts confirming Cicada’s structure or purpose?
Some longform articles and forum posts present claimed insider narratives; they add possible detail but remain unverified by independent primary documentation. Reputable journalism reports these as claims or personal accounts and emphasizes the absence of corroborating official records. Readers should treat them as contested.
How should researchers use this timeline?
Use the timeline to track verifiable public events (posts, signatures, posters). For claims about motive, structure, or affiliation, treat them as hypotheses that require separate corroboration; where sources conflict, note the disagreement and avoid drawing firm conclusions absent new primary evidence.
