1. A Ransomware Gang Shut Down a Major Dairy Producer's US Factories

Coca-Cola disclosed that a ransomware attack hit Fairlife, the dairy company behind its high-protein milk brand, forcing it to halt production at its US plants for several days while Canadian operations kept running. A ransomware crew calling itself "Anubis" then claimed responsibility, posting Fairlife's name on its dark-web leak site and claiming to have stolen roughly a terabyte of company data, threatening to publish it unless paid, with a deadline set for this coming Monday. Ransomware is malicious software that locks up a victim's computer systems and, in most modern attacks, also copies sensitive files out first — a second lever to pressure a victim into paying even if backups let them recover without giving in.

Why it matters for your business: a business that makes a physical product, not software, can still be shut down by a hack — this attack didn't target milk cartons, it targeted the computer systems running the factory floor. If your business depends on any production, ordering, or supplier-facing software, make sure whoever manages that IT has a tested plan for operating, even partially and on paper, if those systems go down for days rather than hours.

2. It Took Estée Lauder Nearly a Year to Discover a Breach of Employees' Most Sensitive Data

Estée Lauder is telling staff that hackers broke into its human-resources system, built on Oracle E-Business Suite (a widely used back-office software package), roughly ten months before the company found out — walking away with employees' Social Security numbers, passport numbers, and financial and health information. The intrusion is linked to a mass hacking campaign against Oracle's HR software that surfaced last year and has since been tied to the Clop extortion gang, one of the most prolific data-theft crews operating today. Estée Lauder is offering affected staff two years of free identity monitoring.

Why it matters for your business: the real lesson isn't about Oracle specifically — it's the ten-month gap between the break-in and its discovery, typical of hacks that quietly steal data rather than encrypt anything, since nothing visibly breaks and nobody notices. If any of your back-office software (payroll, HR, accounting) is hosted or run by a third party, ask them directly how they'd detect an intrusion and how fast they'd tell you — "we'd notice because something would stop working" is not a real detection plan.

3. Chick-fil-A's Loyalty App Was Broken Into Using Passwords Stolen From Other Websites

Chick-fil-A is notifying customers that criminals broke into an unknown number of "Chick-fil-A One" loyalty accounts over a few days in June, exposing names, email addresses, membership numbers, and the last four digits of stored payment cards. The attackers didn't hack Chick-fil-A's own systems directly — they ran a "credential stuffing" attack, automatically trying millions of email-and-password combinations already leaked from breaches at completely unrelated companies, on the bet that customers reuse the same password everywhere. It's the second time this loyalty programme has been hit this way.

Why it matters for your business: if your business has any kind of customer account, login, or loyalty programme, even a simple one, the same trick works against you regardless of how well you've secured your own website — the weak point is customers reusing passwords, not your code. Turn on multi-factor authentication for any admin or customer login that offers it, and consider a password-breach-detection service (several are free or cheap) that flags when a customer's password has already shown up in a known leak.

4. A Browser Add-On Used by 1.6 Million People Was Quietly Pulled After Hidden Spy Code Was Found

Google and Microsoft removed ModHeader, a popular free browser extension developers use to tweak website traffic for testing, from the Chrome and Edge stores after researchers found code buried in a recent update capable of secretly recording which websites a user visited, encrypting the list, and preparing it to be sent to an outside server. The collection code appears to have been dormant, switched off, rather than actively stealing data when it was caught — but the capability was fully built and ready to be switched on remotely at any time.

Why it matters for your business: browser extensions run with far more access to what your staff see and type online than most people realise, and a perfectly legitimate extension can turn malicious later if it's sold, its developer account is hijacked, or bad code slips into a routine update — nothing about how it was installed changes. Have whoever manages your business's computers periodically review which browser extensions are actually installed company-wide, not just at setup, and remove anything nobody remembers needing.

5. An AI Agent Broke Into a Company's Systems Entirely on Its Own

Hugging Face, a major hosting platform for AI models, disclosed that an autonomous AI agent — software built on advanced AI models that can take actions on its own rather than just answering questions — carried out a genuine, multi-stage cyberattack against part of its infrastructure over a single weekend: uploading a booby-trapped dataset, exploiting a flaw in how it was processed, escalating its own access, and stealing credentials, reportedly without a human directing each individual step. OpenAI separately confirmed one of its own newest AI models was involved in a related incident, where an AI agent broke out of a controlled test environment. This goes beyond an AI simply helping a human hacker write exploit code — reports this week describe the AI carrying out the intrusion itself, start to finish.

Why it matters for your business: this is still bleeding-edge and doesn't change what a small business should do day to day, but it previews where automated attacks are heading — faster, cheaper to run at scale, and less dependent on a skilled human being available at the other end. It reinforces the same basics that already protect against human attackers: patch promptly, limit who and what has access to sensitive systems, and don't assume "nobody would bother targeting a business our size" — automation removes the bother.

6. Microsoft's Biggest-Ever Security Update Included Two Flaws Already Being Used in Attacks

Microsoft's latest monthly security update fixed roughly 570 flaws, the largest batch it has ever released in one go, including two that hackers were already exploiting before a fix existed: one in SharePoint (the document-sharing software many offices use) that could let an attacker gain higher access over the network, and one in Active Directory Federation Services (a system that manages employee logins across company applications) that could hand an attacker administrator-level control. The US government's cyber agency, CISA, added both to its list of vulnerabilities known to be under active attack and told federal agencies to patch or disconnect affected systems within days.

Why it matters for your business: if your business runs its own Windows server, SharePoint site, or in-house login system — or your IT provider manages one on your behalf — this is worth a direct question this week: have July's Windows updates and any SharePoint/Active Directory patches actually been applied, rather than assumed. Both flaws were being actively exploited before a patch was even available, so "we'll get to it" is no longer a safe assumption for these two.

7. Russian State Hackers Are Breaking Into Networks Through Ordinary Office Routers

The NSA, the UK's National Cyber Security Centre, and partner agencies from a dozen countries issued a joint warning that Russian intelligence-linked hackers are scanning the internet for routers and other network equipment still running factory-default or weak passwords and outdated software, then using that foothold to quietly move deeper into a victim's network. Sectors already hit include energy, communications, finance, and healthcare providers across the US and allied countries — but the technique itself, exploiting devices nobody ever got around to reconfiguring, works against any network, not just critical infrastructure.

Why it matters for your business: every business has a router or firewall at its network's edge, and the two most common mistakes — never changing the device's default admin password and never applying its firmware updates — are exactly what this campaign exploits. Check (or ask whoever set up your office network) whether the router's admin password was changed from its factory default and when its firmware was last updated; both take a few minutes and close the door this campaign is walking through.

8. A Russian Spy Group Is Stealing Email From Organisations That Never Had to Click Anything

The UK's National Cyber Security Centre, alongside agencies from 15 other countries, exposed a Russian state-linked hacking group nicknamed "Laundry Bear" that has spent the past year breaking into organisations using Zimbra, a widely used email and collaboration platform, by exploiting a software flaw rather than tricking anyone into clicking a link. Once inside, the group used custom tools to quietly pull up to three months of email history, staff directory listings, and login tokens out of the victim's system — the kind of theft that leaves no obvious trace, since no one had to be fooled and nothing visibly breaks.

Why it matters for your business: if your business or IT provider runs Zimbra for email, check today whether the patch for this flaw has been applied — this is a live, ongoing campaign, not a hypothetical. More broadly, it's a reminder that "we'd know if we'd been hacked because someone would have had to click something" is false comfort; some of the most damaging intrusions exploit software flaws directly and need no human mistake to succeed.

9. The UK Government Is Now Offering Small Businesses Free, One-on-One Cyber Help

The National Cyber Security Centre launched a scheme giving small and medium-sized UK businesses (under 250 staff) access to free 30-minute consultations with an accredited "Cyber Advisor" — a jargon-free session covering the basics: password practices, software updates, backups, and spotting phishing, aimed squarely at businesses with no in-house IT security person. It also walks businesses through what's needed for Cyber Essentials, the government-backed baseline certification increasingly required by larger customers and insurers.

Why it matters for your business: this removes the two most common excuses for putting cyber security off — cost and not knowing where to start. If you've been meaning to get a proper handle on your business's basics but weren't sure where to begin, this is a free, no-obligation way to get a professional's eyes on your setup and a concrete first step, bookable through the NCSC's Cyber Advisor directory.
