Trojan-Spy.Win32.Alinaos

Parent class: TrojWare

Trojans are malicious programs that perform actions which are not authorized by the user: they delete, block, modify or copy data, and they disrupt the performance of computers or computer networks. Unlike viruses and worms, the threats that fall into this category are unable to make copies of themselves or self-replicate. Trojans are classified according to the type of action they perform on an infected computer.

Class: Trojan-Spy

Trojan-Spy programs are used to spy on a user’s actions (to track data entered by keyboard, make screen shots, retrieve a list of running applications, etc.) The harvested information is then transmitted to the malicious user controlling the Trojan. Email, FTP, the web (including data in a request) and other methods can be used to transmit the data.

Platform: Win32

Win32 is an API on Windows NT-based operating systems (Windows XP, Windows 7, etc.) that supports execution of 32-bit applications. One of the most widespread programming platforms in the world.

Description

Trojan-Spy.Win32.Alinaos is targeted at point-of-sale (POS) terminals. The Trojan inserts itself into all processes, except for processes in the Trojan's predetermined black list. System processes, browsers, IM clients, and certain other processes are ignored. The Trojan then scans the memory of each process in which it is present, cycling through processes at a certain interval. A regular expression is used to scan memory for credit card information. When information about a credit card is found, all data about the card is sent to the attackers' server. In addition to stealing credit card information, Trojan-Spy.Win32.Alinaos can also download and run files when a command is received from the attackers' server. Several modifications of the Trojan exist and are known under different names: Alina, Katrina, Spark, Joker, and others.
