Credential Harvesting Phishing: How Attackers Steal Login Credentials?

Ever received an email claiming to be from your favorite social media platform, asking you to "verify your account” with a link to enter your credentials? You've likely just had a run-in with a credential harvesting phishing attack in the wild. And trust us, it's not as harmless as it looks.

Credential harvesting phishing attacks have become a go-to weapon for cybercriminals looking to steal login credentials. They’re like digital pickpocketing, except instead of grabbing your wallet, attackers steal your usernames and passwords for easy intrusion access. 

This guide covers what credential harvesting phishing is, how it works, and what your first lines of defense should be.




What is credential phishing?

Credential phishing is a type of cyberattack where criminals trick you into voluntarily handing over your login credentials. It’s not a fancy hack, but it’s reliable as hell for attackers. They create fake websites, emails, or messages that look legitimate to swipe your usernames and passwords for unauthorized access to your accounts.

Here's how a typical credential phishing attack goes down:

  1. The setup: Attackers create a fake login page that looks eerily similar to a legitimate site (like your bank, email, or work) that you’d expect to pop up in your messages. 

  2. The Bait: They send you an email, text, or message from other collaboration apps (Slack, Teams, etc.), insisting that you need to log in right now to resolve this issue. 

  3. The Hook: You’re a responsible human, so you click the link and enter your credentials because it looks like the real website.

  4. The Harvest: Your login information just went straight to the attacker.

What makes credential harvesting phishing so dangerous is that attackers get instant access to your accounts without swanky hacking tools. Your trust is the weakest link in a credential harvest cyberattack. And if you don’t have MFA turned on, it’s game over. They’re in faster than you can scroll to the bottom of the page.  



Credential harvesting vs phishing: what's the difference?

Plot twist. Credential harvesting and phishing aren’t the same thing. Let’s break down the differences because it matters for your security strategies. 

Phishing is the broader umbrella term for any cyberattack that uses deception to dupe victims. It can involve things like:

  • Malware distribution

  • Financial fraud

  • Identity theft

  • Social engineering

Credential harvesting phishing is a specific type of phishing attack focused solely on collecting login credentials. Think of it this way: all squares are rectangles (phishing), but not all rectangles are squares (credential harvesting phishing).

Credential harvesting attacks are laser-focused on your login credentials. They’re mega-valuable to attackers, and here’s why:

  • They’re sold on dark web marketplaces

  • Used to access multiple accounts (your friendly reminder to stop reusing passwords)

  • Put to work for more sophisticated attacks in the future


How credential phishing attacks work

Ready to get behind the attacker’s keyboard? Let's get into the most common credential phishing tactics attackers use to snatch your passwords.

Email-based credential phishing

This is the quintessential approach, and attackers continue to rely on it because it works. They send emails that look like they come from trusted sources, like:

  • Your bank: "Suspicious activity detected. Verify your account immediately."

  • IT department: "Your password expires today. Update it now to maintain access."

  • Popular services: "Your Netflix subscription has been suspended. Click here to reactivate."

The emails often have a dramatic flair to influence you to act fast, and are bedazzled with official-looking logos and links to convincing fake websites.

Website spoofing

If you’re scrolling mindlessly, as we often are, you might gloss right over "amaz0n.com," which looks almost identical (but not quite) to "amazon.com.” Attackers are pros at building lookalike websites using:

  • Similar domain names (typosquatting)

  • Identical visual design

  • Proper SSL certificates to show the "secure" lock icon

  • Realistic URLs that redirect to malicious sites

Smishing and vishing

Attackers will exploit any type of communication for a chance to steal your valuable credentials. So don’t put all your eggs in one basket to guard your email inbox: your phone and social media aren’t off limits:

  • Smishing: aka SMS phishing, involves links to fake login pages through text messages. If your toll road account is dangerously low again, trust us, it’s not the DMV texting you. 

  • Vishing: aka voice phishing, is where attackers try to convince you to share your credentials over a phone call. Think tech support, and they’re asking for access to ‘fix something’ for you. 

  • Social media messages: one of those alleged 5,161 "friends" you have might share malicious links that ask for your credentials.

Business email compromise

Attackers know their audience. For corporate environments, they target high-value accounts by:

  • Impersonating C-Suite executives or IT staff

  • Creating fake internal login portals

  • Copying company branding and terminology

  • Targeting employees whom they know have access


Common warning signs of credential phishing

Here's your credential phishing prevention cheat sheet to help you watch out for these red flags:

Urgent or threatening language: "Act now or your account will be closed!"

Generic greetings: "Dear Customer" instead of your actual name

Suspicious sender addresses: Check carefully. Does your bank normally email you about moving money between accounts?

Unexpected requests: Why would Netflix need you to verify your Social Security number to keep your account active? (Spoiler alert: they don’t.)

Poor grammar and spelling: Legitimate companies proofread their communications before hitting send to massive email databases 

Mismatched URLs: Before clicking any links, take two seconds to hover your mouse and put your eyeballs on them. Does the URL match the company's official website? If it doesn’t, keep your scrolling game moving and ignore it. 

Attachments from unknown senders: Never open attachments unless you know who they’re coming from. Better yet, if you know who it is, call or text them to make sure they actually sent the attachment. Malicious attachments are a common way for attackers to deliver malware.

Too-good-to-be-true offers: You’ve won a trip to Tahiti! So weird because you have no recollection of entering a contest for this once-in-a-lifetime prize, but who cares! Just click the link to share your credentials so they can send you all the info! OR be vigilant and wary of emails promising huge rewards or financial windfalls out of the blue. If they seem way too generous, they probably are.

Requests for sensitive information: Legitimate organizations, like your bank, don’t ask for sensitive information, like passwords or credit card details, over email. When in doubt, contact the company directly through official channels.




Not all sharing is caring…sometimes it’s a credential compromise

By staying alert and recognizing these common credential harvesting phishing tactics, you can take solid steps to protect yourself and your organization from cyber threats. Don’t rely on blind trust when it comes to messages with sketchy links. Verify the scenario before you make a move that involves your account credentials. Don’t feed the phish: think before you click.
