Top dangerous virus

Smith in It started as an infected Word document that was posted up on the alt. This got people curious and when it was downloaded and opened, it would trigger the macro inside and unleash its payload. It also sometimes corrupted documents by inserting a Simpsons reference into them. Smith was eventually caught when they traced the Word document to him. The file was uploaded using a stolen AOL account and with their help, law enforcement was able to arrest him less than a week since the outbreak began.

He cooperated with the FBI in capturing other virus creators, famous among them the creator of the Anna Kournikova virus. A Windows worm first discovered in , it was created by computer science student Sven Jaschan, who also created the Netsky worm. While the payload itself may be seen as simply annoying it slows down and crashes the computer, while making it hard to reset without cutting the power , t he effects were incredibly disruptive, with millions of computers being infected, and important, critical infrastructure affected.

The worm took advantage of a buffer overflow vulnerability in Local Security Authority Subsystem Service LSASS , which controls the security policy of local accounts causing crashes to the computer.

It will also use the system resources to propagate itself to other machines through the Internet and infect others automatically. This led to more than a million infections , taking out critical infrastructures, such as airlines, news agencies, public transportation, hospitals, public transport, etc. Jaschen was tried as a minor and received a 21 month suspended sentence.

Zeus is a Trojan horse made to infect Windows computers so that it will perform various criminal tasks. The most common of these tasks are usually man-in-the-browser keylogging and form grabbing.

The majority of computers were infected either through drive-by downloads or phishing scams. First identified in , it managed to compromise thousands of FTP accounts and computers from large multinational corporations and banks such as Amazon, Oracle, Bank of America, Cisco, etc. Controllers of the Zeus botnet used it to steal the login credentials of social network, email and banking accounts. The entire operation was sophisticated, involving people from around the world to act as money mules to smuggle and transfer cash to the ringleaders in Eastern Europe.

After being exposed to the virus, symptoms usually begin three to fourteen days later and include severe headaches, muscle and bone pain, rashes, and bleeding of the gums. In more serious manifestations of the disease, which include the development of Dengue Hemorrhagic Fever, infected individuals are prone to shock, extreme bleeding, blood plasma leaking, as well as extremely low blood pressure.

Occasionally, the disease also affects the brain, liver, and heart, resulting in organ failure or inflammation of the brain. Diagnosis of the disease is often difficult to establish in its early stages, as the virus mimics many other viral infections. Moreover, treatment for the disease is non-specific, and often involves management of symptoms i. Vaccinations and the maintenance of mosquito populations combined with efforts to reduce mosquito bites appears to be the best course of action in reducing the spread of the Dengue Virus.

First identified in during an outbreak in Congo and Sudan, the virus is believed to have originated with primates, and is transmitted via direct contact with bodily fluids including saliva, mucus, vomit, feces, urine, breast milk, sweat, and tears. Depending on the strain of Ebola, the virus carries an extremely high fatality rate that ranges from twenty-five to ninety percent.

As a relatively new strain, little is known or understood about the disease. As a result, treatment options are limited, with supportive care being the primary course of action for infected individuals. Rapid detection and control of outbreaks has become a matter of national emergency in regions susceptible to viral outbreaks, and have proven effective in controlling the spread of Ebola strains. Of these cases, 1, individuals died. The largest outbreak in West Africa, occurring between and and involving 28, cases of Ebola, resulted in the death of 11, individuals.

Although vaccinations are currently in development to curtail the spread of Ebola during future outbreaks, there is still much to be learned about the virus before positive outcomes can be implemented with effect. Following exposure to the Ebola Virus, incubation takes approximately two to twenty-one days before the onset of symptoms first occurs. Initial symptoms involve a sudden flu-like stage that is characterized by extreme fatigue, high fever, muscle weakness and pain, sore throat, and decreased appetite.

As the virus spreads, nausea, vomiting, abdominal pain and cramps , as well as diarrhea are also common, leading to severe dehydration in many cases. Severe rashes, respiratory problems, and chest pain are also likely to develop within five to seven days, followed by the onset of internal and external bleeding.

In severe cases, individuals often enter a coma in the final stages of the disease, followed by low blood pressure that often results in death. In individuals that survive Ebola, lifelong complications are common, including liver inflammation, deafness, chronic fatigue, poor vision, and decreased appetite. Microscopic image of the Marburg Virus; the deadliest and most dangerous virus in the world. The Marburg Virus is an extremely deadly disease from the Filoviridae family, and is considered the most dangerous virus in the world.

After German workers were exposed to infected Grivet Monkeys, seven of the thirty-one people infected by the virus died shortly after. Although the virus has only had a handful of outbreaks over the last fifty years, mortality rates are incredibly high for the Marburg Virus an astounding 90 percent. The most recent outbreak involved the cases in Angola, where approximately individuals were infected by the virus.

Of these, people died from the disease. In addition to primates, it is believed that Fruit Bats are the primary carriers of the virus. For this reason, individuals exposed to mines or caves for prolonged periods of time are particularly susceptible to the disease. Although little is known about the virus, it is believed that the Marburg Virus spreads between humans via direct contact with broken skin, bodily fluids, or contaminated surfaces such as bedding or clothing that has been contaminated with blood, urine, or fecal matter.

Incubation periods for the virus vary from two to twenty-one days. Initial symptoms often begin rapidly, and include high fevers, headaches, fatigue, muscle aches, severe diarrhea, abdominal pain and cramps , as well as nausea and vomiting. After five to seven days, infected individuals often develop severe bleeding both internally and externally from the gums, nose, and genital regions.

Severe bleeding near venipuncture sites is also common due to the inability of the blood to naturally clot. By the ninth day, death usually follows. Rapid response and control of outbreak areas remains the best option for controlling the spread of Marburg Virus pathogens.

For these reasons particularly its high death rate and lack of treatment options , the Marburg Virus is an incredibly dangerous disease capable of eradicating large populations of people particularly in the event of a Bioterrorist attack.
