By GoldSparrow in Backdoors

Backdoor:PHP/SimpleShell.A is a Trojan infection that cyber hackers may use to gain access to a computer. Backdoor:PHP/SimpleShell.A may represent a real threat to computers' security, allowing a third- party to gain access, install software, remove software or monitor on the victim's activities. If your security program claims that your computer is infected with Backdoor:PHP/SimpleShell.A, you should take steps to remove Backdoor:PHP/SimpleShell.A with the help of a strong anti-malware program that is fully up-to-date immediately. Backdoor Trojans, as their name indicates, are used to create a backdoor into compromised computers that may be used to take over the infected computer and carry out all types of unwanted activities. To prevent Backdoor:PHP/SimpleShell.A infections, a reliable security application is paramount, as well as the installation of all updates, and the use of good safety guidelines when browsing the Web.

How Works the Attack of Backdoor:PHP/SimpleShell.A and Similar Trojans

Trojans like Backdoor:PHP/SimpleShell.A receive their name after the Trojan Horse from Greek literature. In the same way the famed Trojan Horse was used to deliver soldiers into the city of Troy, Trojans deliver threatening code in the form of a payload, hidden behind an innocuous file. PC security researchers have observed that Backdoor:PHP/SimpleShell.A may be hidden in a GIF file, PDF files, compromised Microsoft Office documents, and several other seemingly harmless files. These, delivered via corrupted email messages or attack websites, may release their payload when executed by the computer user.

How Backdoor:PHP/SimpleShell.A may be Used to Attack a Computer

PC security researchers have noted that Backdoor:PHP/SimpleShell.A is designed to allow a third- party to gain access to the infected computer automatically. This type of access is known as a backdoor. After Backdoor:PHP/SimpleShell.A has installed its backdoor, Backdoor:PHP/SimpleShell.A establishes a connection with a remote server to receive configuration files, deliver data, and enable the subsequent attack resultant from the presence of the Backdoor:PHP/SimpleShell.A backdoor. Backdoor Trojans may be used in association with numerous other types of threats, and may be the first step in a larger attack. Some types of attacks that may be linked to backdoor infections like Backdoor:PHP/SimpleShell.A include:

  1. Backdoor Trojans like Backdoor:PHP/SimpleShell.A may be used to install threatening software on infected computers. After Backdoor:PHP/SimpleShell.A has established the backdoor, third parties may install threats that may be used to monetize the infection. There are several ways of monetizing Backdoor:PHP/SimpleShell.A and other backdoors. Some examples include adware infections, which make money by bombarding the computer user with advertisements; ransomware infections, which take the victim's computer hostage and demand the payment of a ransom; and bogus security software, designed to force inexperienced computer users to pay for a fake security program.
  2. Backdoor Trojans like Backdoor:PHP/SimpleShell.A may be used to collect data from the infected computer. Once the backdoor is established, a keylogger or other component may be installed to monitor the victim's activities. Using data collecting software, third parties may collect online passwords, online banking data, credit card numbers, and other proprietary data. This is a particularly threatening type of infection when it comes to computers located in industries that need to protect their intellectual property. These types of threats also may have a significant effect on the victim's bank account, collecting the victim's money directly.
  3. Backdoor Trojans may be used to turn the targeted computer into a bot. Bots are part of a large network of computers that can be controlled from a remote location. These networks, known as botnets, may be used to send out massive quantities of spam emails, launder money, carry out distributed Denial of Service attacks (DdoS), and hide unlawful data such as forbidden pornographic images or videos. Botnets may be used to allow threats to propagate; third parties may use the infected computer to deliver additional copies of Backdoor:PHP/SimpleShell.A via spam emails to other computer users.
