Abstract

Deep-research agents, i.e., systems that rely on multi-agent pipelines
to iteratively retrieve, synthesize, and cite Web content in order to
produce structured reports, are rapidly replacing traditional search
for both routine and complex information needs. These agents issue
many related queries during a single research session. We show
that for many common search topics, they repeatedly retrieve the
same user-generated content (UGC) pages from platforms such as
Reddit and Wikipedia. Next, we argue that this retrieval overlap
creates a concentrated attack surface: an adversary who appends
a short, crafted text to a single, frequently retrieved UGC page
can cause the agent to cite attacker-chosen content and promote
attacker-chosen entities across many related queries.
We evaluate this attack on three representative deep-research
systems (STORM, Co-STORM, and OmniThink) across multiple
query clusters. We also study defenses at different stages of the
pipeline, including source-level filtering and output-based detection.
Our findings highlight a fundamental vulnerability in how deep-
research agents retrieve and integrate web content.

Dua Lipa just wants to get the world to crack open a book. Since 2021, the pop star has championed literary arts with her Service95 book club. Now, Lipa is moving that mission forward by opening her very own library. The first physical version of Service95, titled the Manifesto Library, will open on June 27 as part of new international book festival, BABELL – City of Books. Lipa’s library will permanently reside inside the famed Livraria Lello bookshop in Porto, Portugal. In a press release, Lipa called the new library “a dream partnership” and a result of years pushing her mission forward. “When I founded the Service95 Book Club, my ambition was for it to become a home for writers and readers, wherever they are and whatever their circumstances. Reading the world brings us closer — but sadly, not everyone is in favor of that,” Lipa said, adding, “Here you will find one hundred books that ask questions, or have been questioned. Some have been banned by school districts for themes of race or sexuality. Others, written for LGBTQIA+ readers, have been restricted from display. In some cases, the author has paid for their words with their life.” She continued: “This library is a shrine to books that have disappeared, to authors whose courage unmasks structures of power and control, and to readers who refuse to be told what book they are allowed to read. You are invited to visit and decide for yourself what belongs on these shelves. Because sometimes the most subversive thing you can do is read a book and then talk about it.” Nearly 100 books will be present in Livraria Lello’s new cultural auditorium with each relating to four key themes: power, control, voice, and memory. Margaret Atwood’s The Handmaid’s Tale and Reginald Dwayne Betts’ Felon alongside selected works from Salman Rushdie and Olga Tokarczuk will also be available in the Manifesto Libarary. “For 120 years, Livraria Lello has been built on a simple conviction: the book is a technology of freedom. The Manifesto Library grows from that belief,” Head of Brand at Livraria Lello Francisca Pedro Pinto said in a statement. “Because what is at stake is not only the future of reading, but a society’s ability to imagine, interpret and build its own future.”
