Terdot Description

Terdot is a banking Trojan that is related to Zeus, a well-known banking Trojan. Terdot is designed to collect information from its victims, including credit card information and online login information. Terdot also is designed to inject an HTML code into the websites visited on the infected computer, allowing it to get information and trick computer users into logging into fake versions of websites inadvertently and carries out other well-known tactics. One aspect of Terdot is that it targets well-known online email services, including Gmail and Yahoo. Curiously, Terdot does not target vk.com, the largest social media platform in Russia. This may indicate some espionage application or a targeted attack functionality associated with the Terdot banking Trojan.

Terdot is a Highly Threatening Banking Trojan

Terdot is designed to receive automatic updates, allowing Terdot's operators and creators to update Terdot and upload new data relating to Terdot. Financial institutions and other online platforms take precautions against Trojans like Terdot, taking special steps in safeguarding accounts and credit card information. There are several ways in which this can be done, including a better monitoring of accounts for any activity that is out of the ordinary and informing customers about possible attacks, risks, and other steps that can be taken to prevent attacks like Terdot actively.

How Terdot Carries out Its Attack

Zeus is an infamous Trojan that is responsible for countless attacks on online banking platforms and other websites. After the code for the Zeus Trojan was leaked online in 2011, numerous variants of this Trojan appeared. Terdot is just one of the many Trojans that take advantage of the availability of Zeus' code to carry out attacks. PC security researchers have connected two types of attacks with Terdot; Man-in-the-Middle attacks and phishing. Both are designed to collect the victims' data, using two different approaches. It is important for online platforms to establish preventive measures to defend themselves against these attacks. It is not enough for computer users to have strong security software that is fully up-to-date; protection against threats like Terdot must be taken on both sides.

There are several techniques associated with Terdot that may not have been in the original Zeus framework. These include the use of open source tools for creating fake SSL certificates and obfuscation techniques that allow Terdot to evade some anti-virus programs. Terdot's Man-in-the-Middle attack also is quite sophisticated, filtering all of the victim's online activity in search for data that then is stored and sent to Terdot's operators. Terdot can manipulate the traffic on online email platforms and social media websites, even creating fake messages and posts that appear to be sent by the victim. Terdot is capable of evading detection and removal techniques, which makes it very difficult to remove completely.

The Terdot Attacks are in the Wild

Although there are countless ways of delivering Trojans like Terdot to the victims' computers, the bulk of Terdot infections are related to the SunDown Exploit Kit. Terdot is being spread through corrupted email messages that include a fake PDF file that installs Terdot through the use of a corrupted JavaScript. As with most banking Trojans, it is important for computer users to take special precautions when handling unsolicited email messages and attachments. This is especially true because threats like Terdot can spread through the use of phishing emails, which trick computer users by using social engineering techniques that make it seem as if the email message is coming from a legitimate source. A skilled security program also should be used.
