Phishing attacks are evolving alarmingly, and no business—large or small—is immune. In 2024, 94% of organizations reported experiencing phishing attacks.
With 3.4 billion phishing emails being sent every single day, these attacks are becoming more frequent and more challenging to detect.
What’s worse, 88% of organizations face spear-phishing attempts in a single year, targeting specific personnel with tailored, convincing messages.
Take, for example, the infamous attack on Twitter in 2020. Hackers used a targeted spear-phishing technique to access high-profile accounts, including those of Elon Musk and Barack Obama, posting fake cryptocurrency giveaways.
The result? Thousands of dollars were lost in minutes, a significant hit to Twitter’s credibility.
Moreover, the cost of a phishing attack is astronomical for businesses. The average financial impact is $4.91 million. Phishing remains one of the most pervasive and costly cybersecurity threats, from economic loss to reputational damage.
With these facts in mind, it’s evident that staying ahead of phishing attacks is crucial for every organization. This blog will explore how phishing works, common types of phishing, and the steps your business can take to protect itself against these increasingly sophisticated threats.
What is Phishing?
Phishing is a cyberattack where malicious actors disguise themselves as legitimate organizations or individuals to deceive people into revealing sensitive information, such as passwords, credit card numbers, or other personal data. Cybercriminals often pose as trustworthy entities, like banks, well-known companies, or government agencies, to trick individuals into handing over their confidential information.
Phishing attacks typically involve communication, such as email, text messages, or phone calls, where the attacker pretends to be someone you trust. The ultimate goal is manipulating the victim into clicking on a malicious link, downloading malware, or providing sensitive data directly.
How Cybercriminals Use Phishing to Deceive Individuals?
Cybercriminals formulate their phishing attempts to appear as legitimate as possible, preying on the victim’s trust and creating a false sense of urgency. For example, you might receive an email that looks like it’s from your bank, warning you about suspicious activity on your account. The email will ask you to click a link to “verify your account,” but the link actually leads to a fake website that steals your credentials.
These attackers rely on social engineering techniques—manipulating human emotions and behaviors, such as fear, curiosity, or urgency—to get the victim to act quickly without thinking. Once the victim clicks a malicious link, downloads a harmful attachment, or provides sensitive information, the attacker can either steal data directly or infect the victim’s device with malware.
Common Characteristics of Phishing Attacks
While phishing attacks can vary in style and sophistication, they often share common characteristics to deceive victims:
- Urgency or Fear: Phishing messages often create a sense of urgency, such as warnings about account closure or suspicious activity, to compel the victim to act quickly without careful consideration.
- Unfamiliar Senders or Addresses: Phishing emails or messages typically come from unfamiliar or slightly altered email addresses (e.g., using subtle misspellings in the domain name).
- Suspicious Links or Attachments: Phishing emails frequently contain legitimate links but redirect users to fake websites. Attachments in phishing messages may also contain malware that compromises the victim’s device when downloaded.
- Requests for Sensitive Information: Phishing messages often ask for personal or financial information, such as passwords, credit card numbers, or Social Security numbers, which legitimate organizations would rarely request through email or text.
- Poor Grammar and Spelling: Many phishing emails are poorly written, with obvious grammatical errors or awkward phrasing that can tip off a vigilant user.
Types of Phishing Attacks
Phishing has evolved, adapting to users’ increasing awareness and security measures. Cybercriminals have developed multiple techniques to exploit different communication channels, making phishing attacks more pervasive and difficult to detect. Here are the most common types of phishing attacks and how they operate:
Email Phishing
Email phishing is the most standard and widespread form of phishing, where attackers send fraudulent emails disguised as legitimate organizations or individuals. The goal is to deceive the recipient into taking actions that compromise their sensitive information, such as clicking on a malicious link, downloading an infected attachment, or providing personal details like usernames and passwords.
These emails often mimic actual correspondence from banks, social media platforms, or service providers, and they commonly use urgency to pressure victims. For example, the email might claim that your account has been suspended or that there's been suspicious activity.
Example: An email from “support@p4ypal.com” claiming there’s an issue with your account, asking you to log in using a link that takes you to a replica of the PayPal website.
Common Tactics:
- Mimicking reputable organizations.
- Using alarming subject lines (e.g., “Action Required: Account Suspended”).
- Embedding malicious links or attachments.
SMS Phishing (Smishing)
Smishing is a form of phishing carried out via text messages (SMS). In these attacks, scammers send fraudulent messages that often appear to come from reputable sources, such as financial institutions, service providers, or government agencies. These messages may claim an urgent need to take action, such as verifying account details or clicking a link to resolve an issue.
Example: You receive a text saying, “Your bank account has been locked due to suspicious activity. Click here to unlock: [malicious link].”
Common tactics:
- Posing as urgent security alerts or promotions.
- Short messages with embedded malicious links.
- Using shortened URLs to disguise the actual destination of the link.
Phone Phishing (Vishing)
Vishing, short for “voice phishing,” is an over-the-phone attack. In these attacks, criminals pose as representatives from trustworthy organizations, such as banks, credit card companies, or even government agencies, to manipulate victims into disclosing personal information. These attackers might claim technical support from well-known companies, telling the victim that their computer is infected and needs immediate attention, or they might pose as bank representatives alerting the victim of unauthorized transactions.
What makes vishing dangerous is the sense of personal interaction. Scammers exploit this to sound convincing, often using spoofed caller IDs to make the call appear legitimate. They may guide the victim through downloading remote access software, providing credit card details, or even transferring funds to a “secure” account.
Example: A scammer posing as your bank’s fraud department calls you and asks you to confirm your account number to block a suspicious transaction.
Common tactics:
- Caller ID spoofing to appear as a trusted source.
- Posing as tech support, government agents, or bank representatives.
- Persuading victims to provide confidential information over the phone.
Social Media Phishing
Social media phishing exploits the popularity of platforms like Facebook, Instagram, LinkedIn, and Twitter. In these attacks, cybercriminals use fake profiles or compromised accounts to send direct messages or post fraudulent links. Phishing attempts on social media often involve luring users into clicking on malicious links disguised as harmless posts or messages, leading them to fake login pages or malware downloads.
Additionally, attackers may create fake accounts that appear to be from a legitimate business or person. They might offer a prize, discount, or service, asking users to click on links or provide personal details to claim the offer. Sometimes, phishing attacks involve impersonating a user’s friend or contact, making the scam seem even more trustworthy.
Example: A message from a friend’s compromised account saying, “Hey, check out this video of you! [malicious link].”
Common tactics:
- Direct messages from fake or compromised accounts.
- Fake offers, giveaways, or contests.
- Fraudulent links embedded in posts or messages.
Spear Phishing
Spear phishing is a more targeted and personalized form of phishing. Unlike standard phishing, which casts a wide net, spear phishing focuses on specific individuals or organizations. Attackers take time to research their victims, learning about their roles, relationships, and preferences to draft highly customized messages that appear authentic.
The personalized nature of spear phishing makes it significantly more dangerous. Since the emails or messages are tailored to the target, they can bypass the recipient’s usual skepticism. Hackers often use spear phishing attacks to steal corporate secrets, obtain unauthorized access to systems, or commit financial fraud. These attacks are commonly seen in business email compromise (BEC) scams, where attackers impersonate high-level executives to request wire transfers or sensitive data.
Example: An employee receives an email from someone posing as their boss, asking them to wire money to a vendor for an urgent project.
Common tactics:
- Highly personalized messages based on detailed research.
- Impersonation of trusted colleagues, business partners, or executives.
- Requests for sensitive information or financial transfers.
How to Avoid Phishing Attacks: Best Practices for Businesses
Phishing attacks pose a significant threat to businesses, often leading to data breaches, financial loss, and reputational damage. Here is how your organization can protect itself against phishing attacks:
Implement Multi-Factor Authentication (MFA)
One of the most effective ways to prevent phishing attacks is by enabling multi-factor authentication (MFA) for all critical business applications, email accounts, and remote work systems. MFA requires users to provide two or more verification methods before accessing sensitive accounts.
Even if an attacker manages to steal login credentials, MFA acts as an additional security layer by requiring another form of identification, such as a one-time password or biometric verification. With MFA, your organization can prevent unauthorized access, even if credentials are compromised. This reduces the likelihood of successful phishing-related account takeovers.
Conduct Security Awareness Training
Phishing attacks often exploit human behavior, making employees the first line of defense. Conducting ongoing security awareness training ensures that staff can recognize phishing attempts and respond appropriately.
Training sessions should cover common phishing tactics, how to spot suspicious emails, and what to do if employees encounter a potential phishing attack. Your organization can combine these training programs with phishing simulations, where employees receive fake phishing emails to test their awareness and improve detection skills.
Utilize Email Filtering
Investing in effective email filtering helps prevent phishing emails from reaching employee inboxes. This involves configuring email filters to be proactive, blocking any message with malicious characteristics, and ensuring they are regularly updated to recognize new phishing techniques.
Advanced filtering solutions scan incoming messages for phishing markers, such as malicious links, suspicious attachments, or altered domain names, and either block or flag these messages as potentially harmful. With advanced email filtering, your organization can automatically identify and quarantine phishing emails, reducing the risk of phishing emails reaching employees.
Monitor Access to Business Accounts
Establish clear policies and tools for managing access to critical systems, especially for remote work environments. Use privileged access management (PAM) solutions to control who can access sensitive systems and enforce the principle of least privilege (PoLP) to ensure employees only have access to the data and systems necessary for their role.
With these practices, your organization can limit sensitive data exposure and reduce the risk of compromised credentials leading to widespread system access. Additionally, your organization must regularly review user access permissions and eliminate access for employees who no longer need it.
Enable Email Encryption
Encrypting emails that contain sensitive or confidential information adds another layer of security. Your organization can implement encryption for all internal and external communications involving sensitive data.
Even if a phishing attacker intercepts email communication, encryption ensures the content remains unreadable without the proper decryption key. End-to-end encryption protects data from unauthorized access during transmission. Moreover, it secures sensitive business communications and prevents unauthorized access to confidential information.
Execute Strong Password Policies
Attackers often exploit weak or reused passwords in phishing attacks. Establishing strong password policies, including regular updates and using complex, unique passwords for each system, reduces the likelihood of compromised credentials. Your organization must enforce password complexity requirements and prohibit password reuse across different systems.
Additionally, your organization can implement password managers to help employees securely store and manage passwords. These practices can protect employee accounts and prevent attackers from quickly accessing systems after credential theft.
Establish an Incident Response Plan
Even with the best prevention measures, phishing attacks may still occur. A clearly defined incident response plan ensures your organization can react swiftly to contain and mitigate the damage. The plan should include steps for identifying, reporting, and neutralizing phishing threats and communication protocols for informing stakeholders and clients if needed.
These steps will minimize damage in case of a successful phishing attack and streamline the response process, reducing downtime and losses. Additionally, your organization can conduct regular incident response drills to ensure your team is prepared to handle actual phishing incidents.
Perform Regular Security Audits
Frequent security audits help detect weaknesses and vulnerabilities within your organization’s cybersecurity posture. These audits evaluate the effectiveness of security measures, identify potential vulnerabilities, and ensure compliance standards are met. Businesses can proactively mitigate potential threats by identifying risks before they lead to incidents.
Your organization can schedule periodic security audits to ensure your cybersecurity measures remain up-to-date and resilient against evolving threats. Third-party auditors can also be included to provide an unbiased and comprehensive evaluation of your security posture.
By implementing these proactive measures, businesses can significantly reduce their vulnerability to phishing attacks. Cybercriminals constantly refine their tactics, but a well-informed, prepared workforce combined with effective policies and strategies can prevent phishing attempts.
