What to look out for today
Two themes to keep on your radar:
- Targeted emails that lead to “quiet” long-term access (malware/backdoor style) rather than an obvious ransomware event. Even if an attack is aimed at government/critical sectors, smaller suppliers and partners can be used as stepping stones.
- Staff trying new AI tools/models with limited-preview access (or claiming they need urgent access), which can increase the risk of data leakage, account takeover attempts, and shadow IT.
Why this matters to smaller businesses
Smaller organisations are often targeted indirectly: attackers may go after an easier entry point (a supplier, contractor, shared mailbox, or outsourced IT account) to reach a bigger target. Separately, new AI offerings and restricted-access previews tend to trigger a wave of “I need access now” requests, which can be exploited through phishing, fake login pages, and risky data-sharing by well-meaning staff.
Warning signs
- Unexpected “document share” or “secure message” emails, especially where the sender claims to be a partner or public-sector body.
- Repeated MFA prompts or login alerts that staff can’t explain (possible account takeover attempts).
- New remote-access tools appearing, or users reporting their device is “running hot/slow” with no clear reason.
- Staff asking to connect business accounts to new AI services, browser extensions, or plugins “just to test something”.
- Emails or Teams/Slack messages saying an AI preview is “restricted” and requesting credentials, payment details, or immediate admin approval.
How attackers may exploit the situation
- Partner impersonation: pretending to be a customer/supplier/government contact to get a user to click, sign in, or open a file.
- Low-and-slow access: aiming for persistent access (backdoor-style) to monitor emails, harvest credentials, and move through shared systems over time.
- AI access bait: using the hype around new models and “limited previews” to lure staff into fake sign-ins, consent screens, or risky data uploads.
What to do today
- Reinforce one rule with staff: don’t sign in via links in emails/messages—open the service directly from a bookmark or your usual portal.
- Check your admin logs: look for unusual sign-ins, new devices, new mailbox rules/forwarding, and repeated failed logins on key accounts (finance, admin, shared mailboxes).
- Lock down AI usage: confirm which AI tools are approved for business use and what data is never allowed (client data, payroll, HR, legal docs, strategy, credentials).
- Backups and recovery basics: confirm you can restore key systems and that your backups are not accessible using the same credentials as day-to-day accounts.
Ask your IT provider
- Are we monitoring for unusual sign-ins and suspicious mailbox changes (forwarding rules, new delegates, new OAuth/app consents)?
- Do we have alerts for new persistent remote-access tools or suspicious background services on endpoints?
- Which AI tools are allowed, and can we restrict unapproved AI sites/extensions on managed devices?
- Are admin accounts separated from everyday email use, and is MFA enforced everywhere (including for outsourced IT access)?
Patch watch - only one short paragraph, and only if relevant
No specific vulnerability-driven “patch now” item from today’s sources. Keep to your normal monthly patching cycle and focus today on identity controls (MFA, sign-in monitoring) and reducing risky sign-ins via email links.
One action today
Send a same-day staff note: “No logging into services (including AI tools) via email links—use bookmarks/known portals only,” and remind them what business data must never be pasted into AI chat tools.
