Browser Session Hijacking

Adversaries may take advantage of security vulnerabilities and inherent functionality in browser software to change content, modify user-behaviors, and intercept information as part of various browser session hijacking techniques.(Citation: Wikipedia Man in the Browser) A specific example is when an adversary injects software into a browser that allows them to inherit cookies, HTTP sessions, and SSL client certificates of a user then use the browser as a way to pivot into an authenticated intranet.(Citation: Cobalt Strike Browser Pivot)(Citation: ICEBRG Chrome Extensions) Executing browser-based behaviors such as pivoting may require specific process permissions, such as SeDebugPrivilege and/or high-integrity/administrator rights. Another example involves pivoting browser traffic from the adversary's browser through the user's browser by setting up a proxy which will redirect web traffic. This does not alter the user's traffic in any way, and the proxy connection can be severed as soon as the browser is closed. The adversary assumes the security context of whichever browser process the proxy is injected into. Browsers typically create a new process for each tab that is opened and permissions and certificates are separated accordingly. With these permissions, an adversary could potentially browse to any resource on an intranet, such as Sharepoint or webmail, that is accessible through the browser and which the browser has sufficient permissions. Browser pivoting may also bypass security provided by 2-factor authentication.(Citation: cobaltstrike manual)

Procedure Examples
Name Description
TrickBot

TrickBot uses web injects and browser redirection to trick the user into providing their login credentials on a fake or modified web page.(Citation: Fidelis TrickBot Oct 2016)(Citation: IBM TrickBot Nov 2016)(Citation: Microsoft Totbrick Oct 2017)(Citation: Trend Micro Trickbot Nov 2018)
Dridex

Dridex can perform browser attacks via web injects to steal information such as credentials, certificates, and cookies.(Citation: Dell Dridex Oct 2015)
Carberp

Carberp has captured credentials when a user performs login through a SSL session.(Citation: Prevx Carberp March 2011)(Citation: Trusteer Carberp October 2010)
Melcoz

Melcoz can monitor the victim's browser for online banking sessions and display an overlay window to manipulate the session in the background.(Citation: Securelist Brazilian Banking Malware July 2020)
Agent Tesla

Agent Tesla has the ability to use form-grabbing to extract data from web data forms.(Citation: Bitdefender Agent Tesla April 2020)
Grandoreiro

Grandoreiro can monitor browser activity for online banking actions and display full-screen overlay images to block user access to the intended site or present additional data fields.(Citation: Securelist Brazilian Banking Malware July 2020)(Citation: IBM Grandoreiro April 2020)(Citation: ESET Grandoreiro April 2020)
QakBot

QakBot can use advanced web injects to steal web banking credentials.(Citation: Cyberint Qakbot May 2021)(Citation: Kaspersky QakBot September 2021)
Cobalt Strike

Cobalt Strike can perform browser pivoting and inject into a user's browser to inherit cookies, authenticated HTTP sessions, and client SSL certificates.(Citation: cobaltstrike manual)(Citation: Cobalt Strike Manual 4.3 November 2020)
Cobalt Strike

Cobalt Strike can perform browser pivoting and inject into a user's browser to inherit cookies, authenticated HTTP sessions, and client SSL certificates.(Citation: cobaltstrike manual)
IcedID

IcedID has used web injection attacks to redirect victims to spoofed sites designed to harvest banking and other credentials. IcedID can use a self signed TLS certificate in connection with the spoofed site and simultaneously maintains a live connection with the legitimate site to display the correct URL and certificates in the browser.(Citation: IBM IcedID November 2017)(Citation: Juniper IcedID June 2020)
Chaes

Chaes has used the Puppeteer module to hook and monitor the Chrome web browser to collect user information from infected hosts.(Citation: Cybereason Chaes Nov 2020)
Ursnif

Ursnif has injected HTML codes into banking sites to steal sensitive online banking information (ex: usernames and passwords).(Citation: TrendMicro BKDR_URSNIF.SM)

Mitigations
Mitigation Description
User Training

Train users to be aware of access or manipulation attempts by an adversary to reduce the risk of successful spearphishing, social engineering, and other techniques that involve user interaction.
User Account Management

Manage the creation, modification, use, and permissions associated to user accounts.
Man in the Browser Mitigation

Since browser pivoting requires a high integrity process to launch from, restricting user permissions and addressing Privilege Escalation and Bypass User Account Control opportunities can limit the exposure to this technique. Close all browser sessions regularly and when they are no longer needed.

Detection

This may be a difficult technique to detect because adversary traffic may be masked by normal user traffic. New processes may not be created and no additional software dropped to disk. Authentication logs can be used to audit logins to specific web applications, but determining malicious logins versus benign logins may be difficult if activity matches typical user behavior. Monitor for Process Injection against browser applications.
