Scam Emails (Phishing)
‘Dodgy’ emails designed to trick recipients out of money and data
Pronounced ‘fishing’, they are emails from individuals or organisations you ‘think’ you know. They mimic phrasing, branding and logos to appear ‘real’, before conning users to click on a link or attachment.
Here, they defraud users by asking them to provide or confirm their personal information, such as passwords and credit card numbers, or to pay a fake account. They can also send an attachment, designed to look genuine, with malware inside.
People with money – it is a numbers game
Phishing emails are typically sent to thousands of people. Even if only a small percentage of recipients fall for the scam, they can net significant data and sums of money.
- Phishing (low sophistication, many targets) Usually general emails with obvious warning signs, sent to thousands of targets
- Spear Phishing (high sophistication, less targets) Fraudulent and sophisticated messages sent to a specific individual, usually the business owner, receptionist or finance and payroll manager
- Whaling (high sophistication, less and high value targets) Spear phishing aimed at very big fish like CEOs
Emails, SMS, Instant Messaging, Social Media
Phishing scams are not limited to emails. They are increasingly sophisticated and harder to spot.
Be cautious of:
- Requests for money, especially if urgent or overdue
- Bank account changes
- Requests to check or confirm login details
Malicious Software (Malware)
Unauthorised software designed to cause harm.
Malware is a blanket term for malicious software including viruses, spyware, trojans and worms.
Disrupt. Damage. Deceive.
Typically, for profit.
Malware gains access to important information such as bank or credit card numbers and passwords. It can also take control or spy on a user’s computer. What criminals choose to do with this access and data includes:
- Other serious crimes
Malware creators can be anywhere in the world. They just need a computer, technical skills and malicious intent. Criminals can easily access cheap tools to use malware against you. It is not personal – they are not targeting you specifically – it is just business.
NEVER PAY A RANSOM
You are not guaranteed to regain access, and may be vulnerable to a second attack.
Certain malware that locks down your computer and files until a ransom is paid
Ransomware attacks are typically carried out via a malicious but legitimate looking email link or attachment. When downloaded or opened, most ransomware encrypts a user’s files, then demands a ransom to restore access – typically payable using cryptocurrency, like Bitcoin
Ransom, an age-old and effective crime, is now being committed online. Ransomware offers cyber criminals a low-risk, high-reward income. It is easy to develop and distribute. Also in cyber criminals’ favour, most small businesses are unprepared to deal with ransomware attacks.
Small, medium and large businesses
Many small businesses are often less security conscious, are less likely to implement cyber security measures, and spend less on cyber security measures.
