This malware arrives on a system as a file dropped by other malware. It may also be installed manually by a user.Upon execution, it drops a copy of itself and another file that contains its stolen information.

It monitors the Internet Explorer activities of the affected system. It logs keystrokes when a user accesses a Web site containing certain strings in its title bar.

It attempts to retrieve information from Web sites of certain banking institutions.

It gathers information by logging user keystrokes. It steals sensitive information, such as user names and passwords and saves it in a file. This routine risks the exposure of sensitive user information, which may then lead to the unauthorized use of the stolen data.

It sends its stolen information to a remote site via HTTP POST.

cacosh

CACOSH(3)						   BSD Library Functions Manual 						 CACOSH(3)

NAME

     cacosh -- complex inverse hyperbolic cosine function

SYNOPSIS

     double complex
     cacosh(double complex z);

     long double complex
     cacoshl(long double complex z);

     float complex
     cacoshf(float complex z);

DESCRIPTION

     cacosh(z) computes the inverse hyperbolic cosine of the complex floating-point number z, with a branch cut on the interval [-inf, 1] along
     the real axis.

     cacosh() returns values in a half-strip of the complex plane with positive real part and imaginary part in the interval [-Pi, Pi].

     For all complex floating point numbers z, cacosh(conj(z)) = conj(cacosh(z)).

SPECIAL VALUES

     The conjugate symmetry of cacosh() is used to abbreviate the specification of special values.

     cacosh(+-0 + 0i) returns 0 + Pi/2 i.

     cacosh(x + inf i) returns inf + Pi/2 i, for finite x.

     cacosh(x + NaN i) returns NaN + NaN i, for finite nonzero x.

     cacosh(-inf + yi) returns inf + Pi i, for finite positive-signed y.

     cacosh(inf + yi) returns inf + 0i, for finite positive-signed y.

     cacosh(-inf + inf i) returns inf + 3Pi/4 i.

     cacosh(inf + inf i) returns inf + Pi/4 i.

     cacosh(+-inf + NaN i) returns inf + NaN i.

     cacosh(NaN + yi) returns NaN + NaN i, for finite y.

     cacosh(NaN + inf i) returns inf + NaN i.

     cacosh(NaN + NaN i) returns NaN + NaN i.
