Ethical Hacking - Trojan Attacks

Trojans are non-replication programs; they don’t reproduce their own codes by attaching themselves to other executable codes. They operate without the permissions or knowledge of the computer users.
Trojans hide themselves in healthy processes. However we should underline that Trojans infect outside machines only with the assistance of a computer user, like clicking a file that comes attached with email from an unknown person, plugging USB without scanning, opening unsafe URLs.
Trojans have several malicious functions −
  • They create backdoors to a system. Hackers can use these backdoors to access a victim system and its files. A hacker can use Trojans to edit and delete the files present on a victim system, or to observe the activities of the victim.
  • Trojans can steal all your financial data like bank accounts, transaction details, PayPal related information, etc. These are called Trojan-Banker.
  • Trojans can use the victim computer to attack other systems using Denial of Services.
  • Trojans can encrypt all your files and the hacker may thereafter demand money to decrypt them. These are Ransomware Trojans.
  • They can use your phones to send SMS to third parties. These are called SMS Trojans.

Trojan Information

If you have found a virus and want to investigate further regarding its function, then we will recommend that you have a look at the following virus databases, which are offered generally by antivirus vendors.

Quick Tips

  • Install a good antivirus and keep it updated.
  • Don’t open email attachments coming from unknown sources.
  • Don’t accept invitation from unknown people in social media.
  • Don’t open URLs sent by unknown people or URLs that are in weird form.

Animal Cell

 By Lasisi Halima Billy   All animal cells are multicellular. They are eukaryotic cells.  A nimal cells  are surrounded by plasma membrane and it contains the nucleus and organel les that are membrane bound. A nimal cells are of various sizes and have irregular shapes.  Most of the cells size range between 1 and 100 micrometers and are visible only with help of microscope.  Trillions of cells are found in the human body.  There are many different types of cells, approximately 210 distinct cell types in adult human body.   Animal Cell Definition    Animal cells are eukarytoic. Animal cells are have outer boundary known as the plasma membrane.  T he nucleus and the organelles of the cell are bound by a membrane.  The genetic material (DNA) in animal cells...

Light Microscope vs Electron Microscope.

Both light microscopes and electron microscopes use radiation (light or electron beams) to form larger and more detailed images of objects (e.g. biological specimens, materials, crystal structures, etc.) than the human eye can produce unaided. (See also: What is eyesight ? ) An electron microscope is a microscope that uses beams of electrons instead of rays of visible light to form highly magnified images of tiny areas materials or biological specimens. Comparing light vs electron microscopes is made more complicated by the fact that there are different types of electron microscopes. The two main types of electron microscope are the Transmission Electron Microscope (TEM) and Scanning Electron Microscope (SEM). Other types of electron microscope include the Scanning Tunneling Microscope (STM) and Field Emission Transmission Microscope (FE-TEM). Brief notes, see the tables lower down this page for figures, explanations and comments: ...
