I think I just got phished – What should I do?

A no-panic guide to damage control when you’ve clicked something suspicious

First things first: Breathe

That moment when you realise you might have just walked into a digital trap? Your heart starts racing, your mind goes to worst-case scenarios and you’re probably wondering if you’ve just cost your business millions or put everyone’s data at risk.

Stop. Take a breath. You’re not the first person this has happened to and you definitely won’t be the last.

The reality is that most phishing attempts fail not because people are perfect at spotting them, but because quick, smart responses can neutralise threats before they cause real damage. What you do in the next few minutes matters more than the fact that you clicked in the first place.

The “oh no” moment: Quick damage assessment

Before you panic, figure out what actually happened. Not every suspicious click results in immediate danger and understanding your situation helps you respond appropriately.

Level 1: Just clicked a link

  • You clicked but the page didn’t load properly, or you immediately closed it
  • No information was entered anywhere
  • Nothing was downloaded

Level 2: Visited a fake website

  • You landed on a page that looked like a login screen or form
  • The site asked for information but you didn’t provide any
  • You realised it was suspicious and left

Level 3: Entered information

  • You typed in usernames, passwords, or personal details
  • You submitted a form before realising it was fake
  • You provided payment or financial information

Level 4: Downloaded something

  • A file automatically downloaded to your device
  • You opened or ran a downloaded file
  • Your device started behaving strangely after clicking

Each level requires different responses, but all of them are manageable with the right approach.

Your emergency response plan

Step one: Cut the connection

This isn’t about being dramatic – it’s about buying yourself time to think clearly while preventing any potential malware from phoning home or spreading.

On a computer: Disconnect your ethernet cable or turn off Wi-Fi immediately 

On mobile: Switch to airplane mode or turn off cellular data 

Work device: Follow your company’s incident protocol if you have one

Think of this like turning off the water at the stop tap when you spot a leak – you’re preventing a small problem from becoming a big one.


Step two: Assess what you shared

Be honest about what information you might have given away. This isn’t about blame – it’s about knowing what needs protection.

If you entered work credentials: Your company accounts are potentially at risk 

If you used personal passwords: Any accounts with the same password are vulnerable

If you provided payment info: Your financial accounts need immediate attention 

If you shared personal details: Identity theft protection may be necessary

Write this down. You’ll need these details when you report the incident.


Step three: Sound the alarm (the right way)

At work: Contact your IT department immediately, even if it feels embarrassing 

Personal device: If it affects work accounts, still notify your employer 

No IT department: Contact whoever handles your company’s technology

What to tell them:

  • When it happened (approximate time)
  • What you clicked on and where it came from
  • Whether you entered any information
  • What you’ve done since (like disconnecting from networks)

Remember: IT departments deal with this stuff constantly. You’re not confessing to a crime – you’re reporting a security event that needs attention.


Securing your data

Password triage

Not all passwords need changing immediately, but some are more critical than others.

Change immediately:

  • Any password you entered on the suspicious site
  • Passwords for financial accounts if you shared financial information
  • Work accounts if this happened on a work device or involved work email

Change soon:

  • Passwords that are similar to what you might have entered
  • Any accounts using the same password (we know, we know – but now’s the time to fix this)
  • Important accounts like email, banking and cloud storage

Pro tip: If you’re overwhelmed, start with your email password. Email accounts are often the keys to everything else, since password resets usually go through email.

The device health check

Look for immediate red flags:

  • Unusual pop-ups or advertisements
  • Programs you don’t recognise running
  • Slow performance or strange behaviour
  • New browser toolbars or homepage changes

If your device seems fine: Still run a security scan with whatever antivirus software you have 

If something seems off: Don’t ignore your instincts – get technical help

Setting up monitoring

For the next few weeks, you’ll want to keep a closer eye on your accounts than usual.

Financial accounts: Check daily for unauthorised transactions 

Email: Look for messages you didn’t send, especially in your sent folder 

Cloud storage: Watch for files you didn’t create or changes you didn’t make 

Work systems: Report any unusual behaviour to IT immediately

This isn’t about paranoia – it’s about early detection. Most attacks don’t happen instantly and catching something early makes all the difference.


Special situations that need extra attention

When work email gets compromised

Email accounts are particularly dangerous because they can be used to spread attacks to your entire contact list. If there’s any chance your work email was compromised:

  • Check your sent folder for messages you didn’t send
  • Look for forwarding rules you didn’t create
  • Watch for out-of-office messages you didn’t set up
  • Alert colleagues that your account might be compromised

Financial information at risk

If you entered banking details, credit card numbers or other financial information:

  • Contact your bank immediately to report potential fraud
  • Consider placing fraud alerts on your accounts
  • Monitor credit reports for unusual activity
  • Keep documentation of what happened for dispute purposes

Personal information exposure

If you shared personal details:

  • Consider identity theft protection services
  • Monitor credit reports more frequently
  • Be extra suspicious of phone calls or emails asking for verification
  • Keep records of the incident for potential future reference

The recovery timeline: What to expect

Immediate (First 24 hours)

  • Disconnect and secure compromised accounts
  • Report the incident to relevant parties
  • Begin monitoring for unusual activity
  • Document what happened while it’s fresh in your memory

Short-term (First week)

  • Complete security scans and follow IT recommendations
  • Change remaining vulnerable passwords
  • Watch for signs of unauthorised account access
  • Follow up with anyone you notified about the incident

Medium-term (First month)

  • Continue monitoring financial and important accounts
  • Implement better security practices (two-factor authentication, password managers)
  • Stay alert for delayed attacks or social engineering attempts
  • Review and improve your personal security habits

Long-term (Ongoing)

  • Maintain heightened awareness of similar attacks
  • Share lessons learned with colleagues or friends
  • Keep security software updated
  • Remember that vigilance is ongoing, not a one-time fix


Making this a learning experience

Understanding what made it convincing

Take some time to analyse why the phishing attempt worked. This isn’t about beating yourself up – it’s about getting smarter.

Common factors that make phishing successful:

  • Urgency (“Your account will be closed in 24 hours”)
  • Authority (appearing to come from your boss or IT department)
  • Familiarity (using your name, company details, or recent events)
  • Fear (threats about security breaches or legal consequences)

Understanding these tactics helps you spot them next time.

Building better habits

Use this experience as motivation to strengthen your security practices:

Consider implementing:

  • A password manager to generate and store unique passwords
  • Two-factor authentication on important accounts
  • Regular security awareness training
  • A more skeptical approach to urgent requests via email

Remember: The goal isn’t to become paranoid about every email – it’s to develop better instincts about when to slow down and verify.


When to worry (and when not to)

Signs this might be serious

  • Your device is behaving unusually after the incident
  • You’re seeing unauthorised activity in accounts
  • You receive follow-up communications from the attackers
  • IT discovers evidence of network compromise

Signs you’re probably okay

  • Quick disconnection prevented information exchange
  • No unusual account activity after a week
  • Security scans come back clean
  • IT gives you the all-clear

Most importantly: Trust the experts helping you. IT professionals and security teams see this stuff regularly and can assess the actual risk better than anxiety-driven worst-case scenarios.


The bigger picture: You’re not alone

This happens to everyone

Cyber security professionals get phished. IT managers click suspicious links. CEOs fall for sophisticated social engineering. You’re in good company and anyone who claims they’ve never been fooled either hasn’t been targeted much or isn’t being honest.

You’re part of the defence

By reporting the incident quickly and following proper response procedures, you’ve actually contributed to your organisation’s security. Your experience provides valuable intelligence about current attack methods and helps improve defenses for everyone.

Prevention is ongoing

Security isn’t a one-time achievement – it’s an ongoing practice. Every phishing attempt you encounter, whether you fall for it or not, is an opportunity to get better at recognising and responding to threats.

Your action checklist

Right now:

  • Disconnect from networks if you haven’t already
  • Document what happened while it’s fresh
  • Report to IT or relevant authorities
  • Change compromised passwords

Today:

  • Run security scans on affected devices
  • Review and secure important accounts
  • Set up monitoring for unusual activity
  • Consider enabling two-factor authentication

This week:

  • Continue monitoring accounts
  • Follow up on security scan results
  • Implement any recommendations from IT
  • Review and improve security practices

This month:

  • Maintain heightened account monitoring
  • Share lessons learned appropriately
  • Evaluate overall security posture
  • Stay alert for follow-up attempts


Remember: quick response beats perfect prevention

You can’t go back and un-click that link, but you can control what happens next. Most phishing attacks are opportunistic rather than targeted, which means quick response often neutralises them completely.

The difference between a close call and a disaster usually isn’t whether someone clicks a malicious link – it’s how quickly and effectively they respond when they do.

You’ve already taken the most important step by recognising the problem and taking action. Trust the process, follow the recommendations and give yourself credit for handling a challenging situation responsibly.
