Phishing attacks are becoming more sophisticated, with cyber criminals employing increasingly advanced tactics to deceive individuals and organisations. These attacks encompass a range of methods, from traditional email phishing to newer and more complex techniques such as “quishing” and other evolving approaches. As a result, the scope of phishing attacks is constantly expanding.
Phishing
Is a prevalent cyber attack that covers various types of attacks. The National Cyber Security Centre reports that as of August 2023, there were over 23 million reports of phishing attacks. This type of attack is often used as a gateway to more malicious cyberattacks, such as the deployment of malware and ransomware or the collection of valuable credentials for sale on the dark web. Attackers may execute these attacks via email, phone calls, or text messages.
To help organisations protect against phishing attacks, we have compiled a list of the top 5 types of phishing attacks and provided advice on how to identify and prevent them.
Email Phishing:
One of the most common types of phishing attacks is email phishing. Cybercriminals pose as legitimate senders to deceive individuals into divulging their personal or financial information or downloading malware or viruses. They often copy genuine emails from reputable businesses and use malicious links, documents, or image files.
Here are some tips on how to identify a phishing email:
- Look for spelling and grammatical mistakes.
- Check the sender’s email address.
- Verify suspicious attachments or links.
- Beware of urgency and threats.
Spear Phishing
Unlike general email phishing campaigns that are sent to a large number of people, spear phishing is a targeted attack on specific individuals or organisations. Spear phishing attackers conduct extensive research to personalise their phishing emails based on the characteristics, interests, and vulnerabilities of their targets. This makes the phishing email appear highly convincing, increasing the chances of acquiring sensitive information like login passwords or infecting the target’s device with malware.
Business Email Compromise (BEC), also known as CEO Fraud, is a type of spear phishing attack aimed at tricking employees into taking harmful actions, such as sending money to the attacker. By assuming the identity of an authoritative figure, like a CEO, cybercriminals exploit this trust to deceive employees.
Vishing
Vishing, or voice phishing, is a type of phishing attack that takes place over the telephone or VoIP systems, where scammers impersonate legitimate organisations to trick victims into divulging sensitive information such as credit card numbers, passwords, PINs, or other confidential data. The rise of AI and voice cloning technology makes it increasingly easy for scammers to clone a person’s voice to deceive a victim.
Smishing
Smishing attacks involve sending fraudulent text messages (SMS) to individuals to trick them into taking certain actions. Like email phishing, smishing messages often contain urgent or exciting content, such as compromised bank accounts, package delivery notifications, or winning a prize. To protect yourself against smishing attacks, be cautious when receiving unsolicited text messages, particularly those that request personal or financial information. Always verify the authenticity of the message and avoid clicking on links from unknown sources.
Phishing attacks continue to be a significant threat to individuals and organisations. To protect against these attacks, it’s crucial to remain vigilant and employ the strategies outlined above to identify and prevent phishing attempts. By staying informed and implementing best practices, you can reduce the risk of falling victim to a phishing attack.
Quishing Attacks
Which exploit the trust users place in QR codes, have become increasingly common. In these attacks, malicious QR codes are distributed via email, leading unsuspecting victims to fake websites where their login credentials and financial data can be stolen, or malware can be distributed. Despite the potential dangers, many email security measures fail to detect these attacks.
To avoid becoming a victim of quishing, it is essential to exercise caution when scanning QR codes. Always preview the link before clicking, and be especially careful if the sender is unknown. If you do fall victim to a malicious QR code, you could end up on a phishing website, where cyber criminals can access your payment information and credit card details. Alternatively, your device may be infected with malware, which can cause major privacy and security issues.
Protecting yourself and your business from phishing attacks is critical. Some key steps you can take include:
– Practising good cyber hygiene: Educating employees about the risks of phishing and the importance of security awareness can help reduce the likelihood of attacks.
– Using an email security solution: Advanced email security solutions like Mimecast offer unparalleled protection against phishing, spear-phishing, malware, and spam. These solutions use cutting-edge threat intelligence and multi-layered detection engines to keep your systems safe.
– Endpoint Detection and Response (EDR): EDR solutions are highly effective in detecting and mitigating phishing threats by monitoring endpoint activity for unusual or malicious behaviour. If an endpoint tries to download a malicious attachment or visit a phishing website, the EDR system can flag and block the activity.
– Implementing a data backup plan: Backing up data is essential for business continuity, and storing backups remotely or in the cloud can enhance protection and accessibility.
– Protecting your accounts: Multi-factor authentication (MFA) can significantly enhance security and help mitigate the risks associated with phishing attacks by making it much harder for attackers to gain unauthorised access to your accounts.
By taking these steps, you can protect yourself and your business from the damaging effects of phishing attacks and stay safe in an increasingly complex digital landscape.
