Old Bitly Links Are Being Hijacked: Comments

Bitly confirmed an infrastructure issue that allowed unauthorized third parties to claim dormant link endings and redirect historic web traffic to external destinations, according to ransomnews.com's report. Attackers repurposed short links embedded in posts published years ago by global brands, altering where users were sent without gaining access to corporate social media accounts. Bitly suspended the offending accounts and deactivated the modified redirection targets on 15 November 2026.

This report documents how dormant short addresses were repurposed, which public figures and corporate accounts were impacted, and how the link generation mechanism enabled the hijack. Security engineers, marketing administrators, and archive managers will find technical verification steps showing how historical assets remain vulnerable across public communication channels.

01Repurposed corporate restaurant links

A short link posted by Burger King on 24 July 2011 to promote a restaurant locator was re-registered on 15 November 2026 at 05:32 UTC. Instead of directing followers to the restaurant search page, the re-registered address redirected visitors to Wikipedia's list of Nazi concentration camps. Burger King never suffered an account compromise, but an X post quoting the redirected link accumulated over 2.2 million views within hours before the original tweet became unavailable.

Eighteen minutes prior, at 05:14 UTC on 15 November 2026, an inactive link in a 7 June 2011 tweet from McDonald's was claimed by an outside user. The link had originally pointed to a marketing campaign developed by the company's Swedish division, but the new registration redirected traffic to Wikipedia's entry covering the September 11 attacks. The McDonald's post was also taken offline shortly after the discovery of the changed destination.

By 19:22 UTC on 15 November 2026, Bitly deactivated both redirected addresses, replacing the destinations with a standard deactivation notice. Neither brand experienced an administrative breach, as all redirection changes occurred directly on Bitly's domain routing infrastructure.

02Link metadata inspection and timestamps

Every Bitly short address maintains a public information page accessible by appending a plus sign to the end of the URL. Appending this symbol reveals the creation timestamp alongside the registered target destination. Querying the Burger King link bit[.]ly/19BFiM confirmed that the active entry had been generated on 15 November 2026 at 05:32 UTC rather than during the tweet's original 2011 publication window.

Testing confirmed the reliability of the timestamp logging mechanism on verified historic links across independent platforms. A short link generated by an independent developer in 2009 correctly displayed a 2009 creation date on its informational overview. Similarly, a custom link published on 21 June 2017 showed a registration date of 20 June 2017.

Note: Bitly documentation states that links remain active indefinitely and that unique back-halves cannot be reused even after account deletion.

03Repurposed addresses across political archives

Analysis of 97 Bitly short links extracted from a public archive of Donald Trump's posts between 2009 and 2013 revealed systemic re-registration patterns. While 40 of the tested links preserved their initial destinations, 56 links carried registration dates falling after the publication date of the corresponding post. A 57th address had already been flagged and blocked by Bitly as spam or malicious content.

Seven links within the Trump archive had been redirected to completely unrelated targets. Four of these seven addresses were claimed on the morning of 15 November 2026 between 07:49 UTC and 09:57 UTC, pointing visitors to a Roblox gaming profile, two YouTube clips, and an article covering Jeffrey Epstein. In one post from April 2011, three separate links intended to display family video recordings were all replaced by unauthorized registrations.

04Back-half reclamation and account policies

The component of a short URL appearing after the forward slash represents the back-half identifier, generated automatically or chosen as an alias. When an account expires or its link is removed, releasing the identifier allows any third party to claim the identical string. Because printed materials, social posts, emails, and QR codes retain the original text, claiming the back-half transfers authority over that traffic without triggering security notifications.

A related link usurpation vulnerability was documented in February 2025 by Disruptionist when memecoin operators acquired deleted Bitly endings from 2013 social updates to promote speculative digital tokens. Bitly previously closed the defect and deactivated hijacked paths, but identical takeover patterns reappeared across multiple accounts on 15 November 2026. Two older archived addresses established in January 2024 and January 2025 redirected users to cloned crypto services.

Bitly accounts inactive for three continuous years remain subject to system deletion under administrative terms. This account decommissioning policy directly conflicts with help documentation guaranteeing that individual link strings cannot be recycled by other customers.

05Platform response and link deactivation

At 19:13 UTC on 15 November 2026, Bitly acknowledged the incident via its official communication channels. The company stated that unauthorized actors repurposed inactive short links to send readers to unintended third-party pages. The platform's trust and safety division suspended the accounts responsible for claiming the strings and began deactivating affected links across its global network.

Independent checks conducted at 19:30 UTC confirmed that six of the seven redirected links identified in the Trump archive returned deactivation screens. The seventh address presented a Bitly system warning stating that the hosting account had been suspended. The 49 previously re-created addresses that preserved the original content destinations remained operational and accessible online.

By 22:30 UTC, platform engineers confirmed that remediation workflows were underway to prevent subsequent reuse of inactive strings. The incident emphasizes that published short links represent ongoing infrastructure dependencies rather than permanent, tamper-resistant internet records.
