This Trojan arrives as attachment to email messages spammed by another malware or a malicious user.

Upon execution, it exploits the Macro Validation Vulnerability in Microsoft Excel wherein a specially crafted document can cause the application to drop and execute an embedded .EXE file.
More information about the said vulnerability can be found here.
Once it successfully exploits the mentioned vulnerability, it is able to execute a shell code which, in turn, runs the embedded .EXE file on the affected system. The said file is detected by Trend Micro as BKDR_ACCDROP.F. It may be downloaded unknowingly by a user when visiting malicious Web site(s).

Validation::Class::Backwards(3pm)			User Contributed Perl Documentation			 Validation::Class::Backwards(3pm)

NAME

       Validation::Class::Backwards - Backwards-Compatibility Layer for Validation::Class

VERSION

       version 7.70

SYNOPSIS

	   package SomeClass;

	   use Validation::Class;

	   package main;

	   my $class = SomeClass->new;

	   ...

	   1;

DESCRIPTION

       Validation::Class::Backwards is responsible for providing deprecated functionality to the Validation::Class::Prototype layer whilst clearly
       remaining separate via namespacing.

       Note: The methods described here will eventually become obsolete and cease to exist. Please review the namespace occasionally and adjust
       your code accordingly. Using methods defined here will generate warnings unless you unset the $ENV{'VALIDATION_CLASS_BC_WARNING'}
       environment variable.

METHODS

   error
       DEPRECATING:

       The error method is used to set and/or retrieve errors encountered during validation. The error method with no parameters returns the error
       message object which is an arrayref of error messages stored at class-level.

	   # set errors at the class-level
	   return $self->error('this isnt cool', 'unknown somethingorother');

	   # set an error at the field-level, using the field ref (not field name)
	   $self->error($field_object, "i am your error message");

	   # return all errors encountered/set as an arrayref
	   my $all_errors = $self->error();

       RECOMMENDED:

	   # see Validation::Class::Errors

	   # set errors at the class-level
	   return $self->errors->add(...);

	   # set an error at the field-level
	   $self->fields->{$field_name}->{errors}->add(...);

	   # return all errors encountered
	   my $list = $self->errors->list;
