Most people know they shouldn’t use weak passwords or click suspicious email links.
Unfortunately, cybercriminals know that too.
Today’s attackers are using more sophisticated techniques to gain access to accounts, often without ever “hacking” a password in the traditional sense. Understanding how these attacks work is one of the best ways to reduce your risk.
Here are seven lesser-known ways hackers compromise online accounts—and what you can do to protect yourself.
1. Cookie Hijacking
When you log into a website, your browser stores a session cookie so you don’t have to log in every time you visit.
If a hacker steals that session cookie through malware, an unsecured network, or another attack, they may be able to access your account without ever knowing your password.
How to reduce your risk:
- Avoid unsecured public Wi-Fi.
- Log out of sensitive websites when you’re finished.
- Keep your browser and operating system updated.
2. SIM Swapping
Many websites still send Multi-Factor Authentication (MFA) codes through text messages.
In a SIM swap attack, criminals convince a mobile carrier to transfer your phone number to a device they control. Once they receive your text messages, they can intercept password reset codes and MFA codes.
How to reduce your risk:
- Use an authenticator app whenever possible instead of SMS verification.
- Add a PIN or passcode to your mobile carrier account.
3. Deepfake Impersonation
Artificial Intelligence has made it easier than ever to create convincing voice recordings and videos.
Cybercriminals may impersonate executives, coworkers, vendors, or even family members to persuade someone to send money, disclose sensitive information, or approve fraudulent requests.
How to reduce your risk:
Always verify unexpected financial or sensitive requests using a separate communication method.
4. Compromised Third-Party Applications
Many online services allow you to connect other applications to your accounts.
While convenient, every connected application becomes another potential point of entry.
If one of those applications experiences a security breach, your information could be exposed.
How to reduce your risk:
- Review connected applications regularly.
- Remove any you no longer use.
- Only authorize trusted vendors.
5. Port-Out Fraud
Port-out fraud is similar to SIM swapping.
Instead of transferring your phone number to another SIM card, criminals move your number to a completely different carrier.
Once successful, they receive calls and text messages intended for you—including account verification codes.
How to reduce your risk:
Most wireless providers offer additional account security features to prevent unauthorized number transfers.
6. Keylogging Malware
Some malware quietly records every key you type.
That includes usernames, passwords, banking information, and other sensitive data.
Because keyloggers operate silently, many users don’t realize they’re infected until after accounts have been compromised.
How to reduce your risk:
- Keep security software updated.
- Avoid downloading software from unknown sources.
- Install operating system and browser updates promptly.
7. AI-Powered Phishing
Phishing emails aren’t what they used to be.
Artificial Intelligence allows attackers to create messages that are grammatically correct, personalized, and highly convincing. Some even mimic writing styles from people you know.
These attacks often look legitimate enough to fool experienced users.
How to reduce your risk:
- Slow down before clicking links or opening attachments.
- Verify unexpected requests independently.
- When in doubt, contact the sender using a known phone number or website.
Build Layers of Protection
No single security tool can stop every cyberattack.
The strongest protection comes from combining multiple security practices, including:
- Strong, unique passwords
- A password manager
- Multi-Factor Authentication (MFA)
- Regular software updates
- Security awareness training
- Endpoint protection
- Reliable backup and disaster recovery
Together, these layers make it significantly more difficult for attackers to compromise your accounts.
