Phishing is a cyberattack where criminals use fake emails, text messages, websites, phone calls, or other communications to trick people into revealing sensitive information, clicking malicious links, downloading malware, or sending money. It is one of the most common forms of social engineering because it targets human trust instead of only technical weaknesses. Phishing can affect individuals, employees, IT teams, and entire organizations, especially when attackers steal passwords, session tokens, financial data, or access to business systems. CISA describes phishing as an attempt to get people to open harmful links, emails, or attachments that may request personal information or infect devices.
Phishing is a security threat that uses deception to make a message look legitimate. The attacker may pretend to be a trusted company, bank, delivery service, software provider, executive, coworker, government agency, or IT administrator.
The goal is usually to make the victim take an action that benefits the attacker, such as:
Clicking a malicious link.
Entering a username and password.
Downloading an infected attachment.
Approving a fake login prompt.
Sharing financial or personal information.
Sending money or gift cards.
Changing payment details.
Giving access to a business system.
The Canadian Centre for Cyber Security defines phishing as a form of social engineering where threat actors send communications that appear legitimate to trick people into revealing information, clicking malicious links, downloading malicious attachments, or transferring money.
A phishing attack usually starts with a message. The message is designed to look urgent, familiar, or trustworthy.
For example, an attacker might send an email that looks like a Microsoft 365 login alert, a bank fraud warning, a shipping update, a password reset notice, or an invoice. The message may include a link to a fake website that looks almost identical to the real one. When the victim enters their credentials, the attacker captures them.
Some phishing campaigns are broad and generic. Others are highly targeted and personalized. Attackers may research the victim’s company, job title, vendors, executives, or recent business activity to make the message more believable.
Phishing often works because it creates pressure. The message may suggest that an account will be locked, a payment will fail, a package will be returned, or an urgent business task needs approval. This pressure is meant to make the recipient act quickly instead of verifying the request.
Email phishing is the most common form. Attackers send fraudulent emails that appear to come from legitimate senders. These emails often contain malicious links, fake login pages, or infected attachments.
The FTC warns that phishing messages often look like they come from companies people know and may claim there is a problem with an account, payment, invoice, delivery, or login attempt.
Spear phishing is a targeted phishing attack aimed at a specific person, department, or organization. Instead of sending the same message to thousands of people, the attacker customizes the message.
For example, an attacker may impersonate a known vendor and send an invoice to the finance team. They may also impersonate a manager and ask an employee to open a file or process a payment.
Whaling is phishing that targets executives or senior decision-makers. These attacks often involve sensitive requests, financial approvals, legal documents, or fake business communications.
Executives are attractive targets because they may have access to financial systems, confidential data, or high-level approval authority.
Smishing is phishing through SMS or messaging apps. These messages may claim to be from a bank, delivery company, government office, payment app, or employer.
Smishing works well because people often check text messages quickly and may not inspect links carefully on mobile devices.
Vishing is phishing by voice call. Attackers may pretend to be bank staff, technical support, law enforcement, or company personnel. The goal is to pressure the victim into sharing information or performing an action.
Clone phishing uses a copy of a real message, but replaces links or attachments with malicious versions. This can be difficult to spot because the original message may look familiar.
Business email compromise, often called BEC, is a phishing-related attack where criminals impersonate executives, vendors, or partners to trick employees into sending money, changing payment details, or exposing sensitive information.
Phishing is dangerous because it can bypass many technical defenses by targeting the person using the system.
A single successful phishing attack can lead to:
Stolen credentials.
Unauthorized access.
Malware infection.
Ransomware deployment.
Financial fraud.
Data theft.
Account takeover.
Vendor payment fraud.
Regulatory exposure.
Business disruption.
Phishing is also dangerous because it often leads to credential theft. Once attackers have a valid username and password, they may access systems in a way that looks normal at first. Verizon’s 2025 Data Breach Investigations Report notes that phishing, pretexting, and credential abuse continue to play a major role in breaches.
Phishing messages are not always obvious, but many have warning signs.
Common phishing indicators include:
Urgent language asking you to act immediately.
Unexpected password reset requests.
Links that do not match the real domain.
Attachments you were not expecting.
Requests for login credentials.
Messages asking for payment changes.
Poor grammar or unusual phrasing.
Sender addresses that look slightly wrong.
Unusual requests from executives or coworkers.
Threats that your account will be closed.
Offers that seem too good to be true.
The FTC recommends protecting accounts and devices by using security software, keeping phones and systems updated, and protecting accounts with multi-factor authentication where possible.
Phishing prevention requires both user awareness and technical controls. Training alone is not enough, and technology alone is not enough. Organizations need layered protection.
Employees should be trained to slow down and verify suspicious messages, especially if the message asks for credentials, payment, access, or sensitive data.
A good rule is simple: do not trust the message just because it looks familiar. Verify through a separate channel.
Multi-factor authentication makes stolen passwords less useful. Even if an attacker captures a password, they may still need a second factor to access the account.
MFA is not perfect, but it significantly improves account protection when combined with strong access controls and user awareness.
Software updates help protect devices from known vulnerabilities. The FTC specifically recommends setting computers and mobile devices to update automatically to help protect against security threats.
Organizations should use email filtering, domain authentication, attachment scanning, link protection, and spam controls to reduce phishing exposure.
Helpful email security controls include SPF, DKIM, and DMARC. These help verify whether a message is authorized to send from a domain, though they do not stop every phishing attempt.
Users should only have access to what they need. If a phishing attack succeeds, limited permissions can reduce the damage.
This is especially important for admin accounts, finance roles, IT systems, and executive accounts.
Monitoring helps detect unusual login patterns, impossible travel events, repeated failed logins, new devices, abnormal endpoint behavior, or unexpected changes.
This is important because phishing prevention can fail. When it does, detection and response become critical.
If someone clicks a phishing link, they should act quickly.
Do not enter any information.
Disconnect from the suspicious page.
Report the message to IT or security.
Change the affected password from the real website.
Enable or review MFA.
Check account activity.
Run a security scan if a file was downloaded.
Contact the bank or service provider if financial information was entered.
The FTC advises people who believe they responded to a phishing email to visit IdentityTheft.gov and follow recovery steps based on what information was exposed.
Level helps IT teams and MSPs manage endpoints remotely, monitor device health, automate tasks, and take action from a centralized platform. While phishing starts with deceptive communication, the impact often reaches endpoints, user devices, access workflows, and IT operations.
For example, after a suspected phishing incident, IT teams may need to check affected devices, review endpoint status, run scripts, isolate issues, update software, or support users remotely. Level supports these operational workflows by giving teams a practical way to monitor and manage distributed endpoints from one place.
For small IT teams and MSPs, this matters because phishing response is not only about identifying the bad message. It is also about acting quickly after a user interacts with it.
Phishing is a scam where attackers pretend to be trusted people or organizations to trick someone into clicking a link, opening an attachment, sharing information, or sending money.
The main goal of phishing is usually to steal sensitive information, such as passwords, financial details, personal data, or business credentials. Some phishing attacks also try to install malware or trick people into transferring money.
No. Phishing can happen through email, text messages, phone calls, social media, messaging apps, fake websites, QR codes, and collaboration tools.
Phishing is often broad and sent to many people. Spear phishing is targeted and customized for a specific person, role, company, or department.
Multi-factor authentication can reduce the risk of stolen passwords being used, but it does not stop every phishing attack. Some attackers use fake login pages, MFA fatigue, or session theft techniques, so MFA should be combined with training, monitoring, and access controls.
Employees should avoid clicking links or opening attachments, verify the request through another trusted channel, and report the message to IT or security.
Phishing is a social engineering attack that tricks people into clicking malicious links, sharing sensitive information, downloading malware, or approving fraudulent requests. It remains a major security risk because it targets human trust and can lead to credential theft, financial fraud, malware infection, and business disruption.
Organizations can reduce phishing risk by combining user education, MFA, email security controls, endpoint monitoring, least-privilege access, software updates, and fast incident response. The best defense is not one tool or one training session. It is a layered security approach that helps users recognize threats and helps IT teams respond quickly when something goes wrong.
