A fraudulent text message can reach an employee when they are away from their managed laptop, outside normal working hours and without the protections they expect in Microsoft 365. A delivery notification, missed-call alert or urgent request from a senior colleague can prompt a tap before the user has considered the risk. Effective smishing awareness training for employees addresses that moment: it helps people identify social engineering on mobile devices, report it quickly and avoid turning a text message into credential theft, payment fraud or malware infection.
For UK organisations, smishing is not a separate awareness concern to be addressed once a year. It is part of the same phishing lifecycle that affects email, collaboration platforms and web services. The channel differs, but the attacker’s objective is familiar: create urgency, impersonate a trusted party and move the recipient towards a harmful action.
Why smishing needs a distinct training approach
Employees often have fewer visual cues available in SMS than in email. A phone screen truncates a sender name and URL, message previews are short, and people are accustomed to receiving legitimate texts from parcel carriers, banks, healthcare providers and authentication services. Attackers take advantage of that familiarity.
The risk also extends beyond corporate handsets. A member of staff may receive a work-related lure on a personal device, particularly where their mobile number is publicly available, used for multifactor authentication or shared with suppliers. Even when the device itself is not managed, a compromised Microsoft 365 password or an approved malicious multifactor prompt can provide a route into corporate systems.
Training should therefore avoid treating SMS as simply ‘phishing on a phone’. It should explain the behaviours that make smishing effective: shortened or deceptive links, sender-ID spoofing, payment pressure, fake account alerts and requests to move a conversation to WhatsApp or another messaging channel. It must also make clear that a message appearing in an existing conversation thread is not proof that it is genuine.
Build smishing awareness training for employees around decisions
Employees do not need a technical lesson on mobile telecommunications protocols. They need clear guidance for the decisions they make in seconds. Training is most effective when it uses realistic scenarios relevant to the organisation’s people, suppliers and operating model.
A finance team may face messages purporting to be from a bank or an executive requesting an urgent payment. Colleagues in healthcare may encounter appointment or patient-record lures. Local authorities, universities and large employers may see parcel, payroll, parking or HR-themed messages. The scenario should match the job context, but the expected response should remain consistent: do not use the link or callback details supplied in the message; verify independently through a trusted route; and report the suspicious message.
This distinction matters. Telling employees to ‘look for bad spelling’ is no longer sufficient. Many fraudulent texts are concise, professionally written and tailored to the recipient. Better training asks employees to pause when a message creates unusual urgency, requests credentials or a payment, introduces an unfamiliar link, or asks them to bypass an established process.
Teach verification, not guesswork
The strongest message is that employees are not expected to determine with certainty whether every text is malicious. They are expected to recognise when a message needs verification. That removes pressure to make a perfect judgement and encourages early reporting.
For example, an employee who receives a text apparently from their bank should open the bank’s official app or type the known web address into a browser. They should not tap the link in the text, even if the message appears convincing. If a text appears to come from a colleague or supplier, the employee should use a known telephone number, directory entry or agreed business channel to verify the request.
Training should also cover the difference between a security alert and a security action. A genuine service may send a notification, but it should not require a user to disclose a password, approve an unexpected authentication request or make a payment from a text link.
Make reporting possible from a mobile device
Awareness without an easy reporting route leaves the security team blind. In email, an Outlook reporting button can capture the suspicious message for phishing triage. SMS presents a different operational challenge: employees need a simple, documented route that works on the handset they use.
Depending on the organisation’s estate and privacy requirements, this may involve forwarding the message to a designated reporting number, sending a screenshot to a monitored service desk channel, or submitting key details through a mobile-friendly reporting process. The method matters less than consistency. Employees should know what to capture: the sender number or name, the full message, the link without opening it, the time received and any action already taken.
The process also needs an explicit path for urgent cases. If an employee has entered credentials, installed an app, approved an multifactor request or provided payment details, they should contact the help desk or security team immediately. Reporting must not feel punitive. Fast disclosure gives incident responders the opportunity to reset credentials, revoke sessions, investigate inbox activity and assess whether other users received the same lure.
Use simulations carefully and measure the right outcomes
Simulated smishing can reveal whether staff can identify realistic lures, but it should be used with care. A poorly designed exercise that creates unnecessary anxiety or imitates a sensitive personal event can reduce trust in the security programme. The objective is to improve judgement and reporting, not to catch people out.
Scenarios should reflect credible threats and be agreed with HR, legal and employee representatives where appropriate. They should not collect personal data unnecessarily or encourage staff to take unsafe actions on their personal devices. For organisations with a bring-your-own-device model, the boundaries of monitoring and testing need particular attention.
Click rate is useful, but it is not enough. A mature human risk management programme examines whether employees reported the message, how quickly they did so, which business areas received the lure and whether the exercise exposed a process problem. If a convincing fake supplier message reaches a procurement team and nobody has a practical verification route, retraining alone is not the answer.
Useful measures include:
- reporting rate and median time to report;
- repeat interaction rates by campaign theme and audience;
- the proportion of users who follow the agreed verification process;
- phishing triage volumes, classifications and response times; and
- recurring themes that indicate a control, supplier or communications gap.
These metrics help security leaders show improvement while focusing investment on the areas of greatest exposure.
Connect training to phishing response and remediation
A reported smishing attempt may be isolated, or it may be part of a broader campaign. A malicious link can lead to a convincing Microsoft 365 sign-in page; stolen credentials can then be used for mailbox rule creation, internal phishing and business email compromise. That is why mobile awareness should feed the same response workflow as email threats.
Security teams should assess reported URLs, sender details and associated indicators against available threat intelligence. Where a user has interacted, responders need a defined playbook that covers identity investigation, session revocation, password reset, multifactor review and endpoint assessment where relevant. If the same campaign has also reached corporate inboxes, remediation may require the organisation to locate and remove related messages at scale.
This operational connection is where training becomes a security control rather than a communications exercise. Employees provide early intelligence from the point of attack. The SOC, help desk and Microsoft 365 administrators must be able to turn that intelligence into triage, containment and remediation.
Keep the programme relevant as attacker tactics change
Smishing themes change quickly. Parcel lures may rise during busy retail periods; tax, banking and invoice messages can reflect current events; QR codes and messaging-app hand-offs can reduce the visible evidence that employees rely on. Annual slide-based training will not keep pace.
A better model combines concise, recurring learning with targeted reinforcement after real campaigns, reported incidents and simulated exercises. Content should be reviewed against the organisation’s actual threat data. If users report repeated fake multifactor alerts, focus on authentication fatigue. If supplier impersonation is common, reinforce call-back controls and payment verification. If QR codes are appearing in both SMS and email, address the common decision point across channels.
Wise Fish approaches phishing protection as an operational lifecycle: prepare users, capture reports, investigate threats, remediate affected messages and use the findings to strengthen defences. That approach is particularly relevant for smishing, where a useful employee report can be the first sign of a wider identity or fraud campaign.
The practical aim is not to make every employee a threat analyst. It is to ensure that, when an unexpected text asks for action, they know how to pause, verify and report - and that the organisation is ready to act on what they send.
