Hackers Steal Digital Keys: Your Session Cookies Are Targets
25 Oct
Summary
- Session cookies act as digital keys, granting hackers access without passwords.
- Malware infection is the primary method hackers use to steal active cookies.
- Logging out manually and clearing cookies are key defenses against theft.
Session cookies are now a primary target for cybercriminals, with billions identified in stolen data circulating online as of June of this year. These cookies function as digital keys, allowing users to navigate websites without repeated logins. However, while a session remains active, these keys can be stolen.
Malware downloaded onto a device is the usual culprit, directly accessing browser databases to extract active session cookies and send them to hackers. This bypasses the need for passwords and can even circumvent multi-factor authentication, making users vulnerable without realizing it.
To combat this threat, users are advised to be cautious about downloaded software and browser extensions, as these can hide infostealer malware. Signs of infection include device slowdowns, rapid battery drain, or unusual browser behavior.
Crucially, users must manually log out of accounts to invalidate session cookies, as simply closing a tab does not end the session. Regularly clearing cookies and utilizing dedicated password managers are also recommended security practices.
