Various forms of malware are multiplying nowadays due to technological developments. Consequently, computer users have become more and more sophisticated.
According to Wikipedia a trojan refers to a form of malware that performs a desirable function but in fact performs hidden malicious functions allowing unauthorized access to the host machine.
The Annual report PandaLabs 2008 indicates that Trojans are still the most significant type of malware, and reaches 77.49%. The malware that has caught my attention lately comes with the technical name Trj/Banker.LNO. It's a trojan, that at first sight seems safe but could very well be the cause of attacks and intrusions.
It should be noted that this type of a trojan captures certain information that is entered or saved by the user, with the equivalent risk to privacy: passwords saved by certain Windows services. Trj/Banker.LNO sends the collected information to a remote user by email, FTP or any other available way. Using certain methods it cannot be detected by antivirus companies.
However, Banker.LNO doesn't have the power to expand automatically by its own means. To reach the affected computer it requires an attacking user's interference. It is transmitted by various means like floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc. Be attentive as Windows 2003/XP/2000/NT/ME/98/95 are the operating systems that can be affected by this Trojan.
Overall, Banker.LNO gives hackers the possibility to get into and perform risky actions in affected computers, like capturing screenshots, stealing personal data, etc. So if you want to protect your PC from this trojan, follow the recommendations below:
- Install a good antivirus in your computer;
- Keep your antivirus updated;
- Keep your antivirus protection enabled at all times.
