Question 26.
Zeus & Trojan
Zeus is a trojan distributed through malicious files hidden in emails and fake websites, in cases involving phishing. It’s well known for propagating quickly and for copying keystrokes, which led it to be widely used in cases of credential and passwords theft, such as email accounts and bank accounts. The Zeus attacks hit major companies such as Amazon, Bank of America and Cisco. The damage caused by Zeus and its variations is estimated at more than USD 100 million since it was created in 2007.
Based on the given information, answer the questions given below. Attempt any four questions:
(a) Are Trojans easy to remove?
(b) Is Zeus malware still active?
(c) Does Zeus have a virus?
(d) Who created ZeuS virus?
(e) What is ZeuS Trojan Removal?
Answer:
(a) Trojan horses are some of the most frustrating viruses that you can get on your computer. Not only are they easy to pick up, they’re not always easy to find. On top of that, Trojan horses are irritating to get off of the computer once they’re there. However, they’re not impossible to remove
(b) Like many forms of malware the Zbot was initially used to steal banking information. However, in 2011, the source code was released to the public, allowing multiple new variants to be created. The original code has apparently been retired, but new generations of Zeus trojans are still active today.
(c) Zeus, ZeuS, or Zbot is a Trojan horse malware package that runs on versions of Microsoft Windows. While it can be used to carry out many malicious and criminal tasks, it is often used to steal banking information by man-in-the-browser keystroke logging and form grabbing.
(d) Hamza Bendelladj
The FBI detained over a hundred people, who were charged with conspiracy to perform bank fraud and cash laundering, 90 of them in the USA and the rest in Europe. Hamza Bendelladj was reported as the mastermind behind Zeus.
(e) Zeus Trojan is malware that targets Windows users 2022 on your Windows 10, you might have installed adware or PUP To remove it, you can try to check all the suspicious installed programs on your computer. Zeus virus can be detected with dedicated tools. Make sure to use a malware remover app.
