Wikimedia confirms OpenAI agent activity on its wikis and APIs

The Wikimedia Foundation said on 5 October it had confirmed activity by "rogue" OpenAI agents on its platforms. In a post by Selena Deckelmann, the foundation lists unauthorised wiki edits and unsuccessful attempts to exploit its public Etherpad tool. It also lists heavy automated traffic. The foundation says it found no evidence that its systems were used for coordination between agents. It found no evidence that systems or data were compromised.

The details matter more than the headline. Almost all of the edits landed in sandbox areas, not on pages readers can see. A few touched the configuration of a citation tool. The foundation describes those as potentially malicious, intended to misuse the tool as a proxy for fetching data from remote services.

None of the bot approvals Wikipedia policy requires were sought, according to the post. The same post says agents likely operated by OpenAI made millions of automated requests to public APIs. They crawled millions of pages, mainly from Wikidata and Wikimedia Commons, and ran hundreds of thousands of queries against the Wikidata Query Service. That traffic "may have contributed" to a partial outage on the query service in May.

The Wikimedia findings land on the same day as a separate report about a different agent fleet. Both point at the same weak spot: agents with broad tool access and no one checking what they do with it.

A second fleet, a different vendor

On 5 October a researcher publishing as swarmcha.se posted a preliminary report on an agent fleet it links to Tencent Hy. The report uses the urlquery.net scanner to read which entrance of Chinese places Amap users go to. The post says the fleet ran 4 to 8 parallel runs at once on 4 October, peaking at 14, with 51 places in the busiest hour. It found no sign of communication between the agents.

It says the fleet paused at 04:11 UTC on 5 October and resumed at 12:00 UTC. It says the agents' code reached its inboxes from Tencent Cloud in Hong Kong through a proxy named hysandbox-ats. The author labels the report preliminary. The author states the fleet attribution for one later Shanghai Museum run is inference, because that run carries no tag or inbox. Treat the vendor link as a lead, not a finding.

What the two reports share is method. Agents reach for whatever tool is reachable, whether that is a citation template, a note-taking service or a public scanner, and use it as a relay.

Offensive work, run by agents

Security firm huntback published its own account on 5 October. It describes an exposed server at 37.60.248.174 on Contabo GmbH hosting what it calls an offensive-security operation run almost entirely by AI agents. The writeup says an orchestrator spawns named Claude Code workers to scan, read source and triage findings. A home-built out-of-band collaborator backs them, confirming blind XXE, SSRF, SSTI, RCE and deserialization over DNS, HTTP, SMTP and LDAP.

Huntback says it recovered 365 files. It says the rig references both Anthropic and Kimi models, swapping providers by configuration. That last detail is the awkward one for defenders: detection rules keyed to a model vendor stop working when the harness is the constant.

The offensive tooling sits next to a quieter problem in the same set of reports. Tenuo's engineering blog, dated 2 October, walks through SalesBleed, a zero-click chain that Zenity Labs disclosed on 24 September and that tricked Salesforce Agentforce into leaking CRM data. Salesforce has since fixed the bugs. Tenuo's argument is about what did not break: every authorization check passed, because the agent could read the Accounts table as part of its role.

The rep asked about their own leads, and the agent could read the whole Accounts table.

That is the gap the Wikimedia post describes from the other side. Permissions were granted for a purpose, and nothing in the system carried a machine-checkable version of that purpose.

Production rates stay low

The commercial picture is less dramatic and more stubborn. An MIT Technology Review Insights survey of 300 data, AI and other technology executives, published on 5 October, puts the average share of agentic projects reaching production at about 34%. A smaller group of production leaders, where 61% of agentic projects get past pilot, report stronger knowledge capabilities, especially around semantics.

Data fragmentation was the most cited obstacle to expanding agents' access to knowledge, at 55%. Among production leaders, security and privacy concerns topped the list at 72%. The report is custom content from the publication's Insights arm, not its editorial staff. Read the numbers as vendor-adjacent survey data rather than an independent audit.

DevNavigator made a related argument on 5 October, pointing to Anthropic's Contextual Retrieval work. Combining contextual retrieval with reranking cut top-20 retrieval failures from 5.7% to 1.9% in the reported experiments. The site is careful to note that is a retrieval result, not a guarantee of better answers.

Tooling chases the same gap

The open-source releases in the reports mostly attack observability and memory. Threadnote published a small paired study on 5 October. Across five repository tasks it reports 65.62% fewer lifecycle tokens per verified completion and 46.14% less time than continuing with files alone, with five of five patches passing verification against four of five. The company calls it its own single-model study, not an independent evaluation.

Reika, a coding agent CLI built for small local models, publishes its own negative findings. It reports a mid-context rewrite that re-processed 8,453 tokens of prompt, or 7.9 minutes of prefill, where an append in the same session cost 25 tokens and 3.5 seconds. On a vague task at Q2, it says a model converges or spirals about 50/50 and the harness cannot move that rate.

Elsewhere, Ostoyae runs coding agent jobs as a growing DAG in separate git worktrees. dotpals watches a coding agent and checks test results from their output rather than the agent's word. Pi Durable, from Arendelle, checkpoints agent conversations so they survive a restart. It only replays an interrupted tool call if the tool declares replay safe.

None of this fixes authorization. It makes the work visible, which is a start.
