MasterBar BHO

Categories: BHO,Hijacker
BHO (Browser Helper Object) Trojan.
The BHO waits for the user to post personal information to a monitored website.
As this information is entered by the user, it is captured by the BHO and sent back to the attacker.
The method of network transport used by the attacker makes this Trojan unique.
Typically, keyloggers of this type will send the stolen information back to the attacker via email
or HTTP POST, which can appear suspicious.
Instead, this Trojan encodes the data with a simple XOR algorithm before placing it into
the data section of an ICMP ping packet." explained the company.
Hijackers are software programs that modify users' default browser home page,
search settings, error page settings, or desktop wallpaper without adequate notice, disclosure,
or user consent.

When the default home page is hijacked, the browser opens to the web page set by the hijacker
instead of the user's designated home page. In some cases, the hijacker may block users from
restoring their desired home page.

A search hijacker redirects search results to other pages and may
transmit search and browsing data to unknown servers. An error page hijacker directs
the browser to another page, usually an advertising page, instead of the usual error
page when the requested URL is not found.

A desktop hijacker replaces the desktop wallpaper with advertising
for products and services on the desktop.

Hijackers take control of various parts of your web browser, including your home page,
search pages, and search bar. They may also redirect you to certain sites should you
mistype an address or prevent you from going to a website they would rather you not,
such as sites that combat malware. Some will even redirect you to their own search engine
when you attempt a search. NB: hijackers almost exclusively target Internet Explorer.
