Cybersecurity is a huge concern for businesses as cyber criminals deploy more and more advanced attacks. Among the various cyber threats, phishing attacks remain one of the most prevalent and dangerous. But what is a phishing attack? How does it work, and what steps can you take to safeguard your sensitive information?
In our latest guide, we’ll explore these questions and delve into the importance of phishing training for your business.
What is a phishing attack?
A phishing attack is a form of cybercrime, where attackers pose as legitimate businesses, organisations or institutions to deceive people into providing sensitive data. This could be anything from login credentials to credit card numbers and personal information.
The term “phishing” is a play on the word “fishing,” alluding to the act of baiting a victim and “reeling” them in.
How does a phishing attack work?
A phishing attack works by tricking individuals into revealing sensitive information. Here’s a step-by-step breakdown of how a typical phishing attack operates:
Preparation
The attacker decides on a target or a group of targets and creates a fraudulent email, message, or website that closely mimics a legitimate one. This can involve copying logos, design elements, and writing styles to appear convincing.
Bait
The attacker sends the fake email or message to the target. This communication typically includes a sense of urgency or a convincing reason for them to act quickly. Examples include claiming that there is a problem with the target’s account, offering a prize, or needing to confirm personal information.
Hook
The target receives the message and is convinced it is legitimate. The message usually contains a link to a fraudulent website or an attachment. The link might look like it directs to a legitimate site but instead leads to a fake one controlled by the attacker.
Capture
When the target clicks the link, they are taken to the fraudulent website, which often looks identical to the real site it is impersonating. They are then asked to enter sensitive information, such as login credentials, credit card numbers, or other personal details.
Alternatively, if the email contains an attachment, opening it might install malware on the target’s device, which can capture sensitive information or provide the attacker with remote access.
Exploitation
Once the target enters their information, the attacker captures it. This data can be used immediately to access the target’s accounts, steal money, or gather more personal information. The stolen information can also be sold on the dark web or used in other types of fraud and attacks.
Aftermath
The attacker may use the information for various malicious activities. This can include financial theft, identity theft, or using the information as leverage in further attacks (e.g. spear phishing, where more targeted attacks are made on specific individuals or organisations).
Common types of phishing attacks
Phishing attacks come in various forms, each employing different techniques to deceive victims. Here are some of the most common types of phishing attacks:
- Email Phishing: The most common type, where attackers send emails that appear to be from legitimate organisations.
- Spear Phishing: Targeted attacks aimed at specific individuals or organisations, often using personalised information.
- Whaling: A form of spear phishing targeting high-profile individuals, such as CEOs or government officials.
- Smishing and Vishing: Phishing attempts via SMS (smishing) or voice calls (vishing).
- Clone Phishing: Duplicate, legitimate emails that have been intercepted and altered with malicious links.
The impact of phishing attacks
The consequences of falling victim to a phishing attack can be severe. According to a report by Verizon, 41% of data breaches in 2022 involved phishing. These breaches can lead to huge financial losses, reputational damage, and legal consequences for the affected businesses.
Data breaches are a severe consequence of phishing attacks. A data breach can result in hefty fines and legal penalties, particularly if customer data is involved and if the organisation fails to comply with data protection regulations like the General Data Protection Regulation (GDPR). The cost of legal fees, regulatory fines, and remediation efforts can be substantial.
Reputational damage is another critical impact. Customers and clients lose trust in an organisation that has been compromised, leading to a loss of business and a decline in market value. Rebuilding a tarnished reputation can take years and involve significant marketing and public relations efforts.
Operational disruptions also occur as organisations must divert resources to address the breach. This includes IT personnel working to secure systems, investigate the attack, and restore services, which can hamper normal business operations and productivity.
Real-world phishing attacks
Real-world phishing attacks have targeted individuals, businesses, and even governments, causing significant financial and reputational damage. Here are a few examples that stand as great examples of why phishing training is worth looking into!
The Target Breach (2013)
In one of the most infamous phishing attacks, hackers gained access to Target’s network by tricking an HVAC contractor with a phishing email. This breach compromised the credit and debit card information of approximately 40 million customers.
The Google and Facebook Scam (2013-2015)
From 2013 to 2015, a Lithuanian man orchestrated a phishing scam that tricked employees at Google and Facebook into wiring over $100 million to fraudulent accounts by posing as a hardware vendor.
The RSA Security Breach (2011)
In 2011, RSA, a major security company, was targeted in a sophisticated phishing attack. Employees received emails containing an Excel spreadsheet with a zero-day exploit. When opened, the spreadsheet installed a backdoor that allowed attackers to access RSA’s network. They stole sensitive data related to RSA’s SecurID two-factor authentication products, which were used by millions of people worldwide. This breach had far-reaching implications, forcing RSA to replace millions of SecurID tokens.
Preventative measures: How to protect against phishing scams
To protect yourself and your organisation from phishing scams, consider implementing the following measures:
Education and training
One of the most effective ways to protect against phishing scams is through regular education and training. Employees should be trained to recognise phishing attempts, including how to spot suspicious emails, links, and attachments. Ongoing training programmes can keep everyone updated on the latest phishing techniques and reinforce the importance of vigilance!
Email filtering
Implementing advanced email filtering solutions can help prevent phishing emails from reaching your inbox. These filters can detect and block malicious emails by analysing their content, attachments, and sender information. Ensuring your email system is equipped with robust spam filters can significantly reduce the risk of phishing attacks.
Two-factor authentication (2FA)
Two-factor authentication adds an extra layer of security by requiring a second form of verification in addition to a password. Even if a phishing scam succeeds in obtaining a user’s password, the attacker would still need the second factor, such as a code sent to the user’s mobile device, to gain access.
Secure browsing practices
Adopting secure browsing practices can help individuals avoid phishing scams. Users should be encouraged to verify URLs before clicking on links and to be cautious of links in unsolicited emails or messages. Hovering over a link to see the actual URL, checking for HTTPS in the web address, and manually typing website addresses can prevent accidental visits to malicious sites!
Regular software updates
Keeping software and systems up to date is crucial in preventing phishing attacks. Regular updates ensure that security vulnerabilities are patched, reducing the risk of malware infections and other exploitations. Both operating systems and applications should be kept current to provide the best defence against threats.
Incident response plan
Having a well-defined incident response plan can mitigate the impact of a phishing attack. This plan should outline the steps to take if a phishing attempt is detected, including how to contain the threat, notify affected parties, and recover from the attack.
Monitoring and reporting
Implementing monitoring tools can help detect suspicious activities that might indicate a phishing attack. Network and email monitoring can provide early warnings of potential threats. Establishing a clear reporting procedure for employees to follow if they suspect a phishing attempt can make sure you’re acting quickly to prevent further damage.
When it comes to preventing a phishing attack, knowledge and preparedness are your best defences. Stay educated, stay secure, and remember: if it looks suspicious, it’s always better to verify before you click!
Recognising a phishing email
Being able to identify phishing emails is crucial in preventing attacks. Here are some common signs of phishing emails:
- Suspicious senders: Emails from unfamiliar addresses or slight variations of legitimate domains.
- Urgent or threatening language: Messages that create a sense of urgency or fear to prompt immediate action.
- Generic greetings: Lack of personalisation, using generic salutations such as “Dear Customer.”
- Spelling and grammar errors: Legitimate companies typically avoid sending emails with noticeable errors.
- Unusual requests: Requests for sensitive information, such as passwords or financial details.
The role of phishing training
Phishing training is essential in creating a robust defence against phishing attacks. By regularly training employees on the latest phishing tactics and prevention strategies, organisations can significantly reduce the risk of falling victim to these scams. Effective phishing training should include:
