Cybercriminals Bypass Passwords to Hijack Online Accounts

Online account security faces growing threats from techniques that allow criminals to bypass traditional password protection. According to a report by Fox News published October 31, 2026, attackers can hijack active login sessions, manipulate authentication requests, take control of phone numbers and exploit malicious software to access personal accounts. These methods can expose email, banking, payment and social media accounts without requiring criminals to obtain the victim's password.

Security experts emphasize that passwords remain important but cannot provide complete protection on their own. One major threat involves stolen login sessions. Websites and applications create digital sessions after users authenticate, allowing them to remain signed in without repeatedly entering passwords.

Criminals who obtain the associated session tokens or browser cookies may use them to access accounts without another verification step.

Users should regularly review connected devices and active sessions, remove unfamiliar access and investigate suspicious login activity. Changing passwords through a trusted device and revoking existing sessions can help limit unauthorized access.

SIM swapping presents another route into personal accounts. Criminals may persuade mobile carriers to transfer a victim's phone number to a SIM card or eSIM they control. Once successful, they can receive calls and text messages, including certain account verification codes.

Unexpected cellular service interruptions, unfamiliar carrier notifications and unrequested password-reset messages can indicate possible phone account fraud. Users can ask carriers about account security PINs, number transfer locks and port-out protection.

For sensitive accounts, passkeys, physical security keys and authenticator applications offer alternatives to text-message verification. Authenticator applications generally do not rely on the user's phone number. Multifactor authentication also faces attacks known as MFA fatigue or push bombing. Criminals repeatedly trigger login approval notifications, hoping users will eventually approve a request simply to stop the interruptions.

Attackers may also impersonate technical support representatives or financial institutions and request one-time verification codes. Users should reject unexpected authentication requests and never disclose security codes to unsolicited callers. Passkeys, security keys and number-matching authentication approvals can provide additional protection against unauthorized sign-ins.

Anyone receiving repeated unexpected prompts should check their account through its official application or website. Information-stealing malware creates another account takeover risk. These programs can collect browser-stored passwords, session cookies, payment details and other sensitive information, depending on their capabilities.

According to the Fox News report, malicious software can reach devices through fake software updates, pirated applications, suspicious email attachments, malicious advertisements and compromised browser extensions. Some infections operate without obvious warning signs.

Keeping operating systems, browsers and security software updated can reduce exposure. Users should also avoid unfamiliar downloads, review browser extensions and run security scans when they suspect an infection. If a device may be compromised, users should secure important accounts through a separate trusted device.

Serious infections may require professional assistance or an operating system reinstall. Malicious applications can also gain access through permissions that users voluntarily approve. A fraudulent productivity application, for example, may request permission to read email, access contacts or manage cloud storage files.

This technique is known as OAuth consent phishing. Criminals exploit legitimate-looking permission screens to persuade users to authorize applications that can access sensitive information.

In some cases, an application's access may remain active even after the account owner changes their password. Consequently, reviewing connected applications and their permissions is an important part of account security.
