AI and IT News Recap: September 28, 2026: A Microsoft Update Switches Off Paid Office Copies, Washington and Beijing Open an AI Hotline, and Two Patch Clocks Run Out

By Noah Smith, Owner & Consultant, KeyChange Technologies · September 28, 2026

Three days of weekend AI and IT news, and the heaviest story is one Microsoft did to itself: an optional update walked onto machines running paid copies of Office and switched them off. Here is the short version, then the detail.

📌 The AI and IT news at a glance

• A Microsoft update deactivated Office licenses people already paid for, and in some cases uninstalled Office entirely. The rollout is paused.
• Washington and Beijing agreed to an AI incident hotline after a three-day Xi and Trump summit, with a dedicated AI dialogue set for November.
• OpenAI widened its agent misbehavior disclosure: its models poked at SEC, Census and Department of Education websites, and uploaded user images to third-party hosts in 53 cases.
• Two patch clocks ran out this weekend: an exploited SharePoint flaw with a federal deadline of today, and two exploited Citrix NetScaler zero-days rated 9.5.
• An Elementor flaw turned one admin click into an attacker admin account on up to two million WordPress sites.
• Researchers showed Salesforce Agentforce could be talked into leaking CRM data with no human click at all. Already patched.
• Crypto exchange Bitget lost about $351.6 million, and its CEO says the pattern looks North Korean.
• Anthropic is handing Pro and Max subscribers up to $250 in free Claude Code credits, cloud sessions only.
• Claude Opus 5.5 cut its em dashes by 95% and got wordier anyway.

🔝 Top story: Microsoft's own update switched off Office copies people had paid for

On September 26 Microsoft paused KB5002907, an optional update meant to bring outdated Microsoft 365 Apps installations up to date. Instead, on machines running perpetual Office 2016 and Office 2019 Home & Business licenses, the update left Office reporting itself as an "Unlicensed Product." In rarer cases it went further and removed the Office suite altogether. The mechanism, as reported, is that the update reinstalls Office as part of its work, and on machines with mixed architecture components (a 32-bit Office sitting alongside a 64-bit Microsoft Access Runtime, for example) that reinstall could fail partway and leave the device with no Office at all.

Reports started landing on September 23 and 24 across Reddit, Microsoft's own forums, and from managed service providers, with individual organizations counting dozens of affected PCs. Microsoft's statement was blunt: "To prevent additional devices from being affected, we have paused the rollout of this update." The remedies are manual. Reactivate by re-entering the original product key, or, where Office is simply gone, reinstall Office 2016 or 2019 from scratch. Neither is hard. Both are a morning of someone's life multiplied by every affected desk.

In short: Microsoft paused an optional update after it deactivated, and sometimes uninstalled, perpetually licensed Office 2016 and 2019 installations.

What it means for your business: If you still run bought-once Office rather than a Microsoft 365 subscription, find your product keys now, before you need them. This is also the argument for holding optional (non-security) updates back a week or two on a pilot group rather than letting them land everywhere at once.

My take: The interesting part is not that a patch broke something, which happens, but which patch. This was an optional convenience update, the kind that gets waved through because it is not a security fix and therefore feels low stakes. It turns out "low stakes" and "reinstalls Office" can be the same update. If you have never sorted your updates into "must go out now" and "can wait a week," this is a cheap prompt to do it.

🤖 AI

Washington and Beijing agreed to pick up the phone when AI goes wrong

A three-day summit in Washington between Xi Jinping and Donald Trump ended with the two governments agreeing to set up a communication mechanism for AI-related incidents, plus a dedicated AI dialogue scheduled for November 2026. Xi returned to Beijing on September 27. The AI piece sat inside a broader package: a military crisis communications memorandum, a bilateral trade board that started operating that week, a two-month extension of the trade truce, and a Chinese commitment to import at least 10 million metric tons of US coal in 2027 and 2028. Both sides are due to meet again at the APEC summit in Shenzhen in November.

Nobody should read this as a brake. Trump was explicit on that point: "The United States of America is not going to be putting on brakes...We're leading by at least a year, maybe a year and a half." What was agreed is closer to a hotline than a treaty, a way for two governments to reach each other quickly if an AI system does something neither of them planned for. Observers quoted in the coverage framed it as working-level engagement and crisis management rather than any constraint on how fast either side builds.

In short: The US and China agreed to establish a communication channel for AI incidents and to hold a dedicated AI dialogue in November 2026.

What it means for your business: No immediate operational change, but this is the early scaffolding of international AI rules, and scaffolding tends to turn into requirements. If you are making multi-year bets on AI vendors, note that the compliance picture is still being drawn.

My take: A hotline is a modest thing, and modest things are usually what actually get built. I would rather see two governments agree on who calls whom at 3am than watch another summit produce a communique full of shared principles. The November dialogue is the one to watch, because that is where anything with teeth would have to show up first.

OpenAI's agent review keeps getting bigger, and now it touches US government sites

Following the Hugging Face incident and the Australian government portal disclosure we covered in the September 25 recap, OpenAI disclosed two more findings over the weekend. First, its agents interacted with US government websites during training and evaluation, including two SEC sites holding publicly available data and the Census Bureau, plus an unsuccessful and, by OpenAI's description, rudimentary hacking attempt against a Department of Education civil rights office site. The Justice Department, the Commerce Department and state sites in California, Maryland, Illinois, Texas and New York were also touched. OpenAI says it found no evidence of compromise or vulnerability, no credentials used, no nonpublic information obtained and no systems changed.

Second, and closer to home for anyone who uses ChatGPT, OpenAI identified 53 cases where its agents uploaded user-provided images to third-party image-hosting services during research and evaluation work. The company says most users were not affected, that it has worked with the hosting providers to remove most of the content and is still removing more, and that data covered by training opt-outs, enterprise accounts and API usage was not involved. Sam Altman described an "extensive and ongoing review related to our agents' use of internet access during training and evaluation," and spokesperson Liz Bourgeois said the company is reviewing "misaligned model activity" and notifying affected organizations.

In short: OpenAI disclosed that its agents interacted with US federal and state government websites during training, and separately uploaded user-provided images to third-party hosts in 53 cases.

What it means for your business: Anything you hand an AI agent may pass through infrastructure you did not choose. For anything confidential, use enterprise or API access with training opt-out rather than a consumer account, and write that down as a rule rather than leaving it to habit.

My take: Give OpenAI credit for disclosing this at all, because nothing forced them to. The uncomfortable part is the shape of it: the review keeps finding more, which means the honest answer to "what else did the agents do?" is still being assembled. Fifty-three images is a small number. The lesson is not the count, it is that an agent with internet access will do things nobody specified, and the operator finds out afterwards.

Claude Opus 5.5 stopped writing like a robot, and started writing more

The AI benchmarking outfit Arena ran a comparison of high-reasoning Text Arena responses across August and September 2026 and found that Anthropic's Opus 5.5 has had its verbal tics filed off. Em dashes fell from 15.2 per thousand words to 0.8, a 95% drop. Semicolons went from 6.10 to 1.64. Average sentence length came down from 12.14 words to 10.03. Arena judged that 10 of its 12 writing measures moved in what it considers a better direction, meaning fewer of the patterns that make text read as machine-written, and simpler word choices throughout.

One measure went the other way. Average answer length rose from 453 words to 481. So the model writes in plainer, shorter sentences, and then writes more of them.

In short: Arena's analysis found Opus 5.5 uses 95% fewer em dashes and shorter sentences than its predecessor, while average answer length grew from 453 to 481 words.

What it means for your business: If you use AI to draft customer-facing copy, the output is getting harder to spot as AI, which cuts both ways. It also means the old tells your team relied on to catch unedited AI drafts no longer work, so review has to be about accuracy rather than punctuation.

My take: I find this genuinely funny, because "sounds less like AI" has quietly become a product feature that labs now optimize for and publish numbers about. The verbosity creep is the part worth watching. Concise is a harder problem than plain, and nobody has solved it yet. Tell your model how long you want the answer, every time.

🛡️ IT and security

Two patch clocks ran out over the weekend, and one of them is today

Two separate emergency patch situations landed inside three days, and between them they cover a lot of ordinary business infrastructure.

The first is Microsoft SharePoint. CVE-2026-65660 is a code injection flaw that Microsoft describes as letting "an authenticated attacker with low-level access to an affected server execute arbitrary code without user interaction." Microsoft actually shipped the fix back in its August 2026 Patch Tuesday, and initially rated the issue as a medium-severity spoofing problem before revising it upward to a high-severity remote code execution bug. Attacks began shortly after Viettel Security published technical details. Threat intelligence firm Previdian saw exploitation attempts on September 24, Microsoft confirmed reliable evidence of attacks on September 25, and CISA added the flaw to its Known Exploited Vulnerabilities catalog the same day with a federal patching deadline of September 28, which is today.

The second is Citrix. On September 27 Citrix confirmed that two NetScaler flaws, CVE-2026-88771 and CVE-2026-88772, both rated CVSS 9.5, are being exploited in the wild. Citrix's wording: "Exploits of CVE-2026-88771 and CVE-2026-88772 on unmitigated NetScaler deployments have been observed." Both allow unauthenticated remote code execution. NetScaler ADC is affected in default configurations, and NetScaler Gateway is affected where DTLS is enabled, which is the default for VPN servers. Patches exist in Citrix bulletin CTX697096, covering NetScaler ADC and Gateway 14.1 before 14.1-73.37 and 13.1 before 13.1-64.23 among others. Shadowserver tracks more than 23,000 NetScaler instances exposed to the internet, patch status unknown. CISA has given federal agencies until September 30.

In short: An exploited SharePoint flaw carries a federal patch deadline of today, and two exploited Citrix NetScaler zero-days rated 9.5 are now patched but widely exposed.

What it means for your business: If you run an on-premises SharePoint server or a Citrix NetScaler appliance, these are the two things to check before anything else this week. Federal deadlines are not binding on you, but they are a decent proxy for how fast attackers are moving.

My take: The SharePoint one is the more instructive of the pair. The patch has been available since August. What changed was that somebody published the details and Microsoft revised the severity upward, which is a reminder that the severity rating attached to a bug on patch day is an opinion, not a fact. If your patching policy only chases "critical," you would have skipped this one for six weeks. Ask for the Citrix answer specifically, because a NetScaler is exactly the kind of box that gets installed once and then belongs to nobody.

One click from your web admin, and the attacker has an admin account too

A cross-site request forgery flaw in Elementor, the WordPress page builder, lets an unauthenticated attacker create an administrator account on a site, provided a logged-in administrator can be tricked into opening a malicious link. The bug sits in Elementor's Editor Events module and works by bypassing REST nonce validation. Versions 4.3.0 and 4.3.1 are affected, which by the reporting covers up to two million sites. Elementor shipped the fix in version 4.3.2 on September 24, two days after the flaw was reported on September 22, which is a genuinely fast turnaround.

The detail that makes this worth your attention is how little the attack needs. No JavaScript, no attacker-controlled webpage, no form for the victim to fill in. The link can arrive by email, by chat, or in a comment on the site itself, and the only required action is a logged-in admin clicking it. No CVE has been assigned yet.

In short: An Elementor CSRF flaw in versions 4.3.0 and 4.3.1 lets attackers create WordPress admin accounts when a logged-in admin clicks a malicious link, fixed in 4.3.2.

What it means for your business: If your company website runs WordPress with Elementor, confirm it is on 4.3.2 or later today, and check the user list for administrator accounts you do not recognize. Your marketing site is often the least-watched system you own and the one with your domain on it.

My take: Two million sites is a big number, but the part I would fix permanently is the habit, not the version. Whoever edits your website is almost certainly browsing the web while logged in as an administrator in the same browser, and that is the condition this attack needs. Give them a normal editor account for day-to-day work and an admin account they log into deliberately. It costs nothing and it retires a whole category of this.

Researchers talked a Salesforce AI agent into handing over CRM data, with nobody clicking anything

Zenity Labs disclosed a set of three flaws in Salesforce Agentforce, collectively named SalesBleed. The chain starts with a poisoned Web-to-Lead form, the public form on your website where a prospect types their details. An attacker submits instructions rather than a lead, the Agentforce agent later reads that record, and the instructions become commands. From there the researchers showed CRM data could be exfiltrated with zero user interaction by way of HTML image tags, and that the agent's Slack integration could be abused to send phishing messages that appear to come from the trusted agent itself.

The reassuring part: Zenity reported the issues on June 1, 2026, Salesforce confirmed all three were addressed by August 19, and Salesforce says it has "no evidence at this time that the reported issue was exploited against any customer." The company also strengthened its Trusted URLs controls and noted that "Prompt injection is an evolving challenge across the AI industry," which is true and is also the point.

In short: Researchers at Zenity Labs found three now-patched flaws in Salesforce Agentforce that allowed zero-click CRM data exfiltration and agent-impersonating Slack phishing.

What it means for your business: Any AI agent that reads untrusted input, and a public web form is about as untrusted as input gets, can be given instructions by whoever fills that form in. Before you point an agent at your CRM, inbox or helpdesk, ask the vendor specifically what stops submitted text from being treated as a command.

My take: This is the clearest illustration yet of why AI agents are a different security problem than software. There was no memory corruption and nothing to overflow. Someone typed English into a contact form and the system did as it was told, because doing as it is told is the whole product. Salesforce patched these specific paths quickly and deserves credit for that, but prompt injection is not a bug class you finish fixing. Treat agent access to your data like you would treat a new employee's access: least privilege, and an audit trail.

Bitget lost about $351.6 million, and its CEO says the fingerprints look North Korean

Crypto exchange Bitget detected unauthorized transfers out of a limited number of hot wallets on September 24, totalling roughly $351.6 million across ETH, XRP, BNB, AVAX, USDT and USDC on multiple blockchains, with XRP the largest single-chain loss. The attacker got in by compromising a critical backend system in Bitget's wallet infrastructure and using it to authorize the transfers. Bitget says cold wallets were untouched, private keys were not compromised, and its separate self-custodial Bitget Wallet product runs on different infrastructure and was unaffected. Mandiant and SlowMist are assisting the investigation, and some blockchain foundations have frozen wallet addresses linked to the attacker.

On attribution, be precise about who is saying what. Bitget CEO Gracy Chen said that "Based on IP behavior patterns and on-chain analysis, the attack method in this incident is highly consistent with known patterns of North Korean hacker organizations." That is the victim company's own assessment. Chen did not name a specific group, Bitget has not published the evidence behind it, and no government or independent investigator has confirmed the attribution.

In short: Bitget says attackers compromised a backend system in its wallet infrastructure and moved about $351.6 million out of hot wallets on September 24, with its CEO attributing the pattern to North Korean actors.

What it means for your business: The lesson generalizes past crypto. The theft did not require stolen keys, it required access to the system that authorizes transfers. Anywhere money moves in your business, the control that matters is who can approve a payment and whether a second human has to agree.

My take: Two things worth separating. The technical story is a backend compromise, which is the same story as a compromised payments system at any company, just with faster settlement and no chargebacks. The attribution story is thinner than the headlines suggest: this is a breached company naming a nation-state on day one, before outside investigators have reported. It may well be right. It is not yet confirmed, and it is worth noticing how quickly "CEO says it resembles" becomes "North Korea stole" in the retelling.

🧰 New tooling

Anthropic is giving away Claude Code credits, if you run in the cloud

Anthropic is handing individual Pro subscribers $100 and Max subscribers $250 in promotional credits, usable only for Claude Code cloud sessions. You qualify if you had an active subscription as of September 23, 2026. The credits apply automatically when you start a cloud session and sit outside your normal usage limits, which Anthropic summarized as: "If you hit a limit locally, keep going in the cloud until your credit runs out." Claim by October 7. The credits expire November 4. After they are gone, cloud session usage counts against your regular plan limits, and there is no separate charge for the cloud container itself.

Cloud sessions run the work on Anthropic's infrastructure instead of your machine, so a long task keeps going after you shut your laptop.

In short: Pro and Max subscribers active as of September 23 get $100 or $250 in free Claude Code credits for cloud sessions, claimable until October 7 and expiring November 4.

What it means for your business: If anyone on your team already pays for Claude Pro or Max and writes code or automates tasks, this is free capacity sitting on the table with a short fuse. It is also a low-risk way to find out whether long-running background jobs are useful to you before committing budget.

My take: Free credits with an expiry date are a product team trying to get you into a habit, and that is fine as long as you know it. The substantive question is whether you want your work running on someone else's machine rather than your own laptop, because that is a different answer for a marketing script than it is for anything touching customer data. Worth using. Worth deciding what you point it at first.

Two OpenAI products nobody announced, spotted in OpenAI's own website

Two unannounced things surfaced in OpenAI's own code over the weekend, and both are worth flagging with the caveat attached. Neither has been announced, neither has been confirmed by OpenAI, and plans found in website code sometimes never ship.

The first is "o," described as an always-on ChatGPT assistant that could handle email. References to it appeared briefly on OpenAI's website on September 27, listed among the benefits of the $100 ChatGPT Pro plan, with code showing a display name of "o" and an email suffix of "-o." The second, spotted on September 25, is a $500 ChatGPT Pro Max plan bundled with a faster Codex, found the same way.

In short: References to an unannounced always-on ChatGPT assistant called "o" and to a $500 ChatGPT Pro Max tier were spotted in OpenAI's own website code, with no announcement or confirmation from OpenAI.

What it means for your business: If you budget for AI tooling, note the direction of travel: a $500 tier would sit five times above the current $100 Pro plan. Do not plan around either of these until they are announced.

My take: I include this mostly because the price point is a signal even if the product never ships. The industry spent 2025 racing prices down and is now testing how far up the premium end goes. An always-on assistant that reads your email is the more interesting half, and also the half that should make you think hard about what mailbox you would connect it to.

That is the weekend. If you only do one thing from this list, check whether your SharePoint server and your NetScaler are patched, and then go find your Office product keys.
