How To Protect Your Business from Phishing Attacks
Phishing attacks are a common and growing threat in the cyber world. Cyber criminals use various methods to lure unsuspecting victims into giving up their personal or financial information, or installing malware or viruses on their devices. Phishing attacks can lead to identity theft, fraud, data breaches, or ransomware infections.
Phishing attacks can take many forms, but they all share the same goal: to trick you into believing that the message or call is from a trusted source. In this article, we will explain the top 5 types of phishing attacks and how you can spot and avoid them.
Email phishing is the most widely used and well-known type of phishing attack. It involves sending fraudulent emails that look like they are from legitimate organisations or individuals. The emails may contain malicious links, attachments, or images that can compromise your device or steal your information.
To identify a phishing email, you should:
Verify the sender’s email address: Phishing emails may use spoofed or similar-looking email addresses to trick you. Always check that the email address matches the official domain of the organisation or person it claims to be from.
Check for spelling and grammar errors: Phishing emails often have mistakes in spelling or grammar, but be aware that some cyber criminals may use advanced AI tools to create more convincing phishing emails.
Inspect any links or attachments: Do not click on any links or open any attachments unless you are sure they are safe. You can hover your mouse over a link to see the actual URL and make sure it matches the official website of the organisation or person it claims to be from. You can also scan any attachments with an antivirus software before opening them.
Watch out for urgency and threats: Phishing emails often try to pressure you into taking immediate action by creating a sense of urgency or threat. They may ask you to confirm your account details, update your password, or claim that you have won a prize or face a penalty. Do not fall for these tricks and always verify the authenticity of the message before responding.
If you receive a suspicious email, do not reply or forward it. Delete it immediately and report it to your IT team.
Spear phishing is a more targeted and sophisticated type of phishing attack that aims at specific individuals or organisations. Cyber criminals conduct extensive research on their targets and tailor their phishing emails based on their characteristics, interests, and vulnerabilities. The goal is to make the phishing email look as authentic and relevant as possible to increase the likelihood of getting a response or a click.
Spear phishing can be used for various purposes, such as stealing sensitive information, infecting devices with malware, or conducting Business Email Compromise (BEC) attacks. BEC attacks are also known as CEO Fraud, where cyber criminals impersonate senior executives or other authoritative figures and trick employees into transferring money or revealing confidential data.
To protect yourself from spear phishing, you should:
Be cautious of unsolicited emails: Even if an email appears to be from someone you know or trust, always verify its source and content before taking any action. Do not rely on the sender’s name or email address alone, as they can be easily spoofed or hacked. If you have any doubts, contact the sender directly through another channel, such as phone or text message.
Use strong passwords and multi-factor authentication: To prevent cyber criminals from accessing your accounts or devices, you should use strong and unique passwords for each account and enable multi-factor authentication whenever possible. Multi-factor authentication adds an extra layer of security by requiring you to enter a code or use a device in addition to your password.
Educate yourself and your colleagues: Spear phishing attacks often target employees who have access to sensitive information or financial transactions. You should be aware of the common signs and tactics of spear phishing and share them with your colleagues. You should also follow your organisation’s policies and procedures for handling suspicious emails and reporting incidents.
Smishing (SMS Phishing)
Smishing is a type of phishing attack that uses text messages (SMS) to deceive victims into taking certain actions. Like email phishing, smishing messages often contain urgent or enticing content, such as compromised bank accounts, package delivery notifications, or that you have won a prize.
It is important to be careful when receiving unsolicited text messages, especially those that ask for personal or financial information. Always check the authenticity of the message and avoid clicking on links from unknown sources. It’s also important to avoid replying to suspicious messages as doing so may mark your phone number as active, making you more vulnerable to further attacks.
Vishing (Voice Phishing)
Vishing is a type of phishing attack that uses phone calls or VoIP systems instead of emails to deceive victims. Cyber criminals pretend to be representatives of legitimate organisations or authorities and try to persuade victims to give up their personal or financial information, such as credit card numbers, passwords, PINs, or other confidential data.
With the advancement of AI and voice cloning technology, it is becoming easier for cyber criminals to mimic a person’s voice and make vishing calls more convincing.
To avoid falling victim to vishing, you should:
Hang up on suspicious calls: If you receive an unexpected call from someone who asks for your personal or financial information, do not provide it. Hang up immediately and call back the official number of the organisation or authority that the caller claimed to be from.
Do not trust caller ID: Caller ID can be easily spoofed or manipulated by cyber criminals to display a fake name or number. Do not trust caller ID alone and always verify the identity of the caller before disclosing any information.
Register your number on the Do Not Call list: You can register your phone number on the Do Not Call list to reduce the number of unwanted calls from telemarketers and scammers. However, this may not stop all vishing calls, as some cyber criminals may ignore the list or use different numbers to bypass it.
Quishing (QR Code Phishing)
Quishing is a type of phishing attack that uses QR codes to trick users into scanning malicious codes via email. This leads them to fake websites that steal login credentials, financial data, or distribute malware. These attacks are simple and bypass many email security measures.
As QR codes have become a vital part of daily life, users have become more trusting of them, making them more susceptible to such attacks. Cybercriminals exploit this trust, launching malicious campaigns.
What happens if you scan a malicious QR code?
You could be taken to a phishing website: By scanning the QR code, unsuspecting victims are directed to what looks like a legitimate website, where they are asked to enter their payment information. Once entered, the cyber criminal can access credit card information.
Your device could be infected by malware: Users can be duped into installing malware on their own devices by scanning an unknown QR code, resulting in major security and privacy issues.
To avoid being a victim of QR code scans, always preview the QR code link before clicking on it. When you scan a QR code, a preview of the URL should show up on your phone. Be cautious when scanning QR codes, especially if the sender’s identity is unknown.
How can we combat phishing?
It is important to take preventive measures to protect yourself and your business from phishing attacks. Below are some steps you can take:
Practice good cyber hygiene: Cyber criminals are more likely to target those who lack security knowledge than IT professionals who will recognise a phishing or impersonation attempt. Cyber security awareness is essential so that your employees understand the risks, know how to spot threats and take the right actions accordingly.
Protect 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 an account, even if they have the password.
Endpoint Detection Response (EDR): EDR solutions are effective in identifying and mitigating phishing threats by detecting unusual or malicious behaviour on endpoints and has the ability to scan files and URLs accessed by endpoints in real time. If an endpoint tries to download a malicious attachment or visit a phishing website, the EDR system can flag and block the activity.
Use an email security solution: Implementing an email security solution provides advanced protection against phishing. With cutting-edge threat intelligence and multi-layered detection engines, the solution offers protection against spear-phishing, malware, and spam.
Implement a data backup plan: Having a data backup plan is crucial to ensure business continuity. Storing backup data remotely or in the cloud enhances protection and accessibility, even if the primary backup fails.
Phishing attacks are a serious threat that can cause a lot of damage to your personal and business data. By following the tips and best practices we shared in this article, you can reduce the risk of falling victim to these attacks and protect yourself and your organisation.
