We recommend administrators restrict access to applications to only those devices that are registered (with Okta FastPass) and managed by Endpoint Management tools, and if they are assessed to have a strong security posture. Authentication policies can be used to restrict access to user accounts based on a range of customer-configurable prerequisites.Okta FastPass also offers strong phishing resistance in most deployment scenarios. Use strong authenticators such as WebAuthn, U2F keys, smart cards: these offer the strongest resistance to “Adversary-in-the-Middle” attacks.Okta offers integrations with several EDR vendors that allow administrators to deny authentication requests from devices exhibiting poor security hygiene.

Endpoint protection software can protect user devices against malware that extracts session cookies from the user’s browser.
We recommend a “defense in depth” approach to protecting your organization:

The advice below is also available to download as an infographic.ĭue to the variety of ways session cookies can be stolen, there is no single solution that will prevent their theft. If the legitimate user logs out (or is logged out by administrators), the session cookie is invalidated. In any successful attack, the attacker is subject to the constraints of the stolen session: both it's duration and the resources accessible during the session. These attacks can be effective against user accounts protected only by factors that rely on codes sent via SMS, email or authenticator apps. If a user is tricked into signing in to the legitimate web application via one of these malicious sites, the attacker can access the user’s credentials and the session token returned to the browser. These phishing sites are able to relay requests between a targeted user and an impersonated web application. Adversary-in-the-Middle AttacksĪttackers also use social engineering to obtain session cookies by directing users to a malicious website that is configured as a reverse proxy server. Once installed, these modules silently extract cookies, which are in turn bought and sold in dark web forums, occasionally accompanied by tools that attempt to mimic the browser configuration used by the target. This malware is often deployed via “cracked” (pirated) games or delivered as malspam.
The majority of malware families the US Cybersecurity and Infrastructure Security Agency (CISA) listed in its Top 10 Malware Strains of 2021 report are capable of stealing session cookies. Many of the most prevalent malware families observed today include ‘infostealer’ modules that have the ability to extract cookies from browser sessions running on an infected machine. Phishing attacks that use transparent HTTP proxies (adversary-in-the-middle attacks).Malware infection on a legitimate user’s endpoint, and.The two most common techniques used to steal session cookies are: If an attacker steals a session cookie and injects it into their browser, they can often access the same session as the legitimate user. The cookie includes an identifier generated by the app that helps keep track of a signed-in user, ensuring they won’t need to sign-in again until the session expires or the user logs out. Session cookies are small blocks of data stored in a user’s browser after they sign-in to a web application. Discuss approaches to detecting abuse of session cookies.
#SESSION HIJACKING HOW TO#
Okta’s Cyber Threat Research team has observed the proliferation of malware designed to extract session cookies from the browser of an infected user, and increasing use of phishing techniques designed to bypass authenticators that rely on a shared secret.īoth of these techniques rely on extracting a session cookie from the browser of a legitimate user that has already authenticated to an application. In some circumstances (outlined below), MFA can be bypassed. It remains one of the most essential and effective controls against account takeovers. Multi-factor Authentication (MFA) is very effective at limiting what an adversary can do with a stolen password.Īccording to research commissioned by Google in 2019, MFA thwarted 99% of automated credential-based attacks and 93% of phishing campaigns.
