What is a Trojan Virus?

A Trojan horse or Trojan is a type of malware that is often disguised as legitimate software. Trojans can be employed by cyber-thieves and hackers trying to gain access to users’ systems. Users are typically tricked by some form of social engineering into loading and executing Trojans on their systems. Once activated, Trojans can enable cyber-criminals to spy on you, steal your sensitive data, and gain backdoor access to your system.

These actions can include:
• Deleting data
• Blocking data
• Modifying data
• Copying data
• Disrupting the performance of computers or computer networks

How Trojans can impact you
Trojans are classified according to the type of actions that they can perform on your computer:

• Backdoor
A backdoor Trojan gives malicious users remote control over the infected computer. They enable the author to do anything they wish on the infected computer – including sending, receiving, launching, and deleting files, displaying data, and rebooting the computer. Backdoor Trojans are often used to unite a group of victim computers to form a botnet or zombie network that can be used for criminal purposes.

• Exploit
Exploits are programs that contain data or code that takes advantage of a vulnerability within application software that’s running on your computer.

• Rootkit
Rootkits are designed to conceal certain objects or activities in your system. Often their main purpose is to prevent malicious programs being detected – in order to extend the period in which programs can run on an infected computer.

• Trojan-Banker
Trojan-Banker programs are designed to steal your account data for online banking systems, e-payment systems, and credit or debit cards.

• Trojan-DDoS
These programs conduct DoS (Denial of Service) attacks against a targeted web address. By sending multiple requests – from your computer and several other infected computers – the attack can overwhelm the target address… leading to a denial of service.

• Trojan-Downloader
Trojan-Downloaders can download and install new versions of malicious programs onto your computer – including Trojans and adware.

• Trojan-Dropper
These programs are used by hackers in order to install Trojans and / or viruses – or to prevent the detection of malicious programs. Not all antivirus programs are capable of scanning all of the components inside this type of Trojan.

• Trojan-FakeAV
Trojan-FakeAV programs simulate the activity of antivirus software. They are designed to extort money from you – in return for the detection and removal of threats… even though the threats that they report are actually non-existent.

• Trojan-GameThief
This type of program steals user account information from online gamers.

• Trojan-IM
Trojan-IM programs steal your logins and passwords for instant messaging programs – such as ICQ, MSN Messenger, AOL Instant Messenger, Yahoo Pager, Skype, and many more.

• Trojan-Ransom
This type of Trojan can modify data on your computer – so that your computer doesn’t run correctly or you can no longer use specific data. The criminal will only restore your computer’s performance or unblock your data, after you have paid them the ransom money that they demand.

• Trojan-SMS
These programs can cost you money – by sending text messages from your mobile device to premium rate phone numbers.

Trojan-Spy
Trojan-Spy programs can spy on how you’re using your computer – for example, by tracking the data you enter via your keyboard, taking screen shots, or getting a list of running applications.

• Trojan-Mailfinder
These programs can harvest email addresses from your computer.

• Other types of Trojans include:
o Trojan-ArcBomb
o Trojan-Clicker
o Trojan-Notifier
o Trojan-Proxy
o Trojan-PSW

​Wenye Samsung Galaxy Note 7 Wazizime simu zao kwa usalama. 

Samsung imetoa wito kwa watu wenye simu aina ya Galaxy Note 7 kuzizima mara moja huku ikifanya uchunguzi kubaini ni kwa nini simu hizo, hata zile ambazo kampuni hiyo ilikuwa imethibitisha kwamba ni salama, zinawaka moto.

Kampuni hiyo ya Korea Kusini imesema itasitisha uuzaji wote wa simu hizo.

Samsung iliwataka watu waliokuwa wamenunua jumla ya simu 2.5 milioni mwezi Septemba kuzirejesha madukani baada ya wateja wengi kulalamika kwamba betri za simu hizo zilikuwa zinalipuka. Walipewa simu mpya ambazo zilidaiwa kuwa salama.

Lakini sasa taarifa zimetokea kwamba hata simu hizo zilizodaiwa kuwa salama zinashika moto.

Mwanamume mmoja jimbo la Kentucky, Marekani anasema aliamka na kupata chumba chake cha kulala kimejaa moshi uliotokana na simu mpya ya Note 7 aliyokuwa ameipata baada ya kurejesha ya awali.

Siku chache awali, abiria kwenye ndege moja Marekani walitakiwa kuondoka kwa dharura ndegeni baada ya simu ya Note 7 kuanza kutoa moshi.

“Kwa sababu usalama wa wateja ni jambo tunalotilia maanani zaidi, Samsung itawataka wasambazaji wote na wauzaji wake kote duniani kusitisha uuzaji na pia ubadilishaji wa simu za Galaxy Note 7 uchunguzi unapoendelea,” kampuni hiyo imesema.

Simu nyengine ya Galaxy Note 7 yashika moto US “Wateja walio na simu asili za Galaxy Note 7 au simu za Galaxy Note 7 za kubadilisha, wanafaa kuzizima na kuacha kuzitumia na badala yake kutumia njia nyingine (kuendelea na shughuli zao),” kampuni hiyo imeongeza.

Ni watu wangapi wameathirika?

Samsung inasema simu zilizoathirika ni takriban 2.5 milioni. Kwa mujibu wa kampuni hiyo, simu 45,000 za Note 7 zimeuzwa Ulaya, na sana Uingereza. Zaidi ya asilimia 75 zilikuwa zimebadilishwa na wamiliki wake wakapewa simu nyingine za Note 7 au mitambo mingine ya Samsung.

Samsung sasa itashindwa na Apple?

Galaxy Note 7 ilitarajiwa na Samsung kuisaidia kushindana na simu ya Apple iPhone 7. Lakini baada ya matatizo hayo, Samsung imeathirika pakubwa na hisa zake kushuka. Hisa za Apple upande mwingine zimepanda sana thamani. Aidha, nembo ya Samsung kama kampuni ya kuaminika imeathirika sana. 

Wakala wa kulinda wateja Marekani amewahimiza watu kutotumia simu za Samsung ambazo wamebadilishiwa.

Mwenyekiti wa usalama katika tume hiyo ya Elliot Kaye amesema uamuzi wa Samsung wa kuacha kuuza simu hizo ni wa busara.
