Hacking vs Phishing Cyber Attacks

Hacking and phishing are both ways of getting access to things they should not have. The difference is how they go about it. Hacking targets systems directly, using technical methods to break in. Phishing targets people, using deception to get someone to hand over access voluntarily.

They are not mutually exclusive. Many attacks use phishing first to get a foothold, then hacking to go further. Understanding the distinction matters because the defences are different. A VPN helps with one. Training and scepticism help with the other. This post breaks down both, and covers what you can actually do to reduce your exposure. If you want to understand why a VPN is part of the picture, we have covered that separately.

What Is Hacking?

Hacking is the unauthorised access to a computer system, network, or device. The attacker exploits technical vulnerabilities rather than asking for your cooperation. You do not need to do anything for a hack to succeed. The weakness is in the system itself.

Common hacking techniques include:

• Brute force attacks: automated systems try thousands of password combinations per second until one works.
• Malware: malicious software installed on a device without the user knowing, via a download, an infected USB drive, or a compromised website.
• SQL injection: inserting malicious code into a web form to manipulate the database behind a website.
• Man-in-the-middle attacks: intercepting unencrypted communications between two parties, typically on unsecured public Wi-Fi.
• Zero-day exploits: attacks that target software vulnerabilities before the developer has released a patch.

The target is usually the system, the network, or the data stored there. Successful hacks can result in stolen credentials, financial data, personal records, or direct control of devices.

Our take: Most consumer-level hacking risk comes from weak passwords, outdated software, and unsecured network connections, not sophisticated state-sponsored attacks. Fixing those three things eliminates the majority of your exposure.

What Is Phishing?

Phishing is a social engineering attack. The attacker does not exploit a technical vulnerability. They exploit a person. The goal is to convince you to hand over credentials, personal information, or money by pretending to be someone trustworthy.

Phishing most commonly arrives via email, but also via SMS (smishing), phone calls (vishing), and fake websites designed to look like legitimate services. The attacker creates a sense of urgency or authority that short-circuits careful thinking.

Common phishing scenarios:

• An email from ‘your bank’ saying your account has been flagged and you need to log in immediately via a link that leads to a fake site.
• A text message from ‘package delivery’ asking you to confirm your address and pay a small customs fee via a link.
• A phone call from ‘tech support’ saying your computer has a virus and asking for remote access.
• A business email compromise where an attacker impersonates a senior employee and asks a finance team member to transfer funds.

Phishing does not require any technical sophistication on the attacker’s part. The 2025 Verizon Data Breach Investigations Report found that phishing remains one of the most common initial attack vectors in confirmed breaches, used in roughly a third of incidents involving external actors.

Our take: Phishing works because it targets decision-making under pressure. The defence is not technical. It is a habit: pause before you click, verify before you act, and treat any unexpected request for credentials or money with scepticism regardless of how legitimate it looks.

How Phishing and Hacking Work Together

Phishing and hacking are frequently used in sequence. Phishing provides the initial access; hacking extends it.

A common attack chain: a phishing email convinces an employee to enter their credentials on a fake login page. The attacker now has valid credentials. They log in legitimately, then use that foothold to move laterally through the network, escalate privileges, and either exfiltrate data or deploy ransomware.

This is why phishing is often called the ‘front door’ of a cyber attack. The technical defences are meaningless if an attacker simply tricks someone into walking them past the lock.

Note: Business email compromise, where attackers impersonate executives to authorise fraudulent transfers, caused more than $2.9 billion in US losses in 2023 according to the FBI’s Internet Crime Complaint Center. It is a phishing-led attack with no hacking required.

Hacking vs Phishing: Full Comparison

Here is how the two attack types differ across the dimensions that matter most for understanding your risk.

	Hacking	Phishing
Primary target	Systems and networks	People
Method	Technical exploits	Psychological manipulation
Skill required	High (usually)	Low to moderate
What attackers want	Data, access, control	Credentials, personal info, money
How it reaches you	Does not require your action	Requires you to click, reply, or call
Common forms	Brute force, malware, SQL injection	Email, SMS, phone, fake websites
Can a VPN help?	Partially (encrypts traffic)	No (works around encryption)
Primary defence	Strong passwords, updates, patches	Scepticism, verification, training

Our take: Phishing is now the more common threat for individual users. It requires less technical skill from the attacker and is harder to defend against purely with software. Your habits and awareness matter more than your security tools when it comes to phishing.

Does a VPN Protect You From Hacking or Phishing?

A VPN encrypts your internet traffic and hides your IP address. That is useful protection against specific hacking vectors, particularly man-in-the-middle attacks on public Wi-Fi. An attacker who intercepts your connection sees encrypted data they cannot read.

What a VPN does not do: protect you from phishing. If you click a link in a phishing email and enter your credentials on a fake website, that data goes directly to the attacker regardless of whether your connection is encrypted. The VPN has no visibility into what you choose to submit in a browser. For a full breakdown of what NordVPN actually protects you from, see our dedicated post.

NordVPN’s Threat Protection feature (available on Plus plans and above) adds a layer that is relevant to phishing. It blocks known malicious domains at the DNS level, which means it can prevent your browser from loading known phishing sites. That is a meaningful secondary defence, but it is not a substitute for scepticism. See current NordVPN plan pricing for what Plus costs versus Basic.

Practical tip: A VPN is a useful part of your security toolkit, not a complete answer. It handles network-level threats. You handle social engineering threats by building habits: verify the sender, check the URL, and treat urgency as a red flag rather than a reason to act fast.

Practical Steps to Protect Yourself

Against hacking:

• Use a unique, strong password for every account. A password manager makes this practical.
• Enable multi-factor authentication on every account that supports it, especially email, banking, and social media.
• Keep software and operating systems updated. Most successful exploits target known vulnerabilities that patches already fix.
• Use a VPN on public Wi-Fi networks to prevent man-in-the-middle attacks.
• Avoid downloading software from unofficial sources. Malware typically travels via pirated software and unofficial download sites.

Against phishing:

• Check the sender’s actual email address, not just the display name. Legitimate companies do not send from gmail.com or misspelled domains.
• Do not click links in emails that ask you to log in to anything. Go directly to the site by typing the URL.
• Treat any unsolicited request for credentials, payment, or personal information with scepticism, even if it looks official.
• Verify unexpected requests from colleagues or executives through a separate channel (call the person directly, do not reply to the email).
• Report phishing attempts to your email provider. It improves filtering for everyone.

Both: keep an eye on whether your email address or passwords have appeared in a data breach. NordVPN’s Dark Web Monitor (included on Plus plans and above) alerts you if your email is found in known breach datasets. You can also use Have I Been Pwned (haveibeenpwned.com) for a free check. If you are still deciding between a free VPN or a paid one, that post covers what you actually lose on the free tier. If you are considering NordVPN’s current pricing, the Plus plan includes Dark Web Monitor.
