10 latest viruses

It could be argued that there was some degree of schadenfreude in the fact that it was slavery and the exploitation of Africa which lead to the epidemics in Europe and North America during the 18th and 19th centuries. Probably the best known of these was the outbreak in Philadelphia, the then capital of the U. This pattern was mirrored throughout America with an estimated , to , deaths during the 18th and 19th centuries. Today, despite an effective vaccine existing, there are in the region of an annual , cases of yellow fever worldwide, killing 30, people each year.

In addition the symptoms are easily confused with Ebola with both classified as acute viral hemorrhagic fevers. The Lassa virus infects virtually every tissue in the human body and outbreaks are usually started through exposure to the local Mastomys rats. If you were in any doubt of the dangers posed by Lassa virus then its biosafety level 4 BSL-4 should convince most of you.

This is the highest level of biosafety reserved for working with pathogens that are likely to cause death and for which there are no vaccines or treatments. Lassa fever causes somewhere in the region of 5, deaths annually.

Endemic throughout West Africa it is estimated to infect over , people each year. Not quite that of Ebola or Marburg viruses, but a scary number all the same. Hepatitis is the name given to collection of viral diseases which attack the liver. There are 5 forms of contagious hepatitis which are given letters A to E.

Of all these the most serious are hepatitis B and hepatitis C which together cause almost a million deaths per annum. These are often passed from mother to child but can also be spread via blood transfusions, tattooing, dirty syringes and sexual activity.

Hepatitis B causes the largest share of fatalities each year around , It is a fairly unremarkable illness with no gory symptoms. The majority of deaths are the result of the illness slowly attacking the liver over a period of years eventually resulting in either liver cancer or cirrhosis. Whilst becoming infected with hepatitis B as an adult usually results in an acute episode of illness which ends up with a full recovery, those infected as children are more likely to develop the long term condition.

Although the overall death rate from hepatitis C is lower than B it still kills an estimated , people a year, mostly in the developing world. Rabies is one of several deadly diseases belonging to the Lyssavirus genus. This stage includes the classic symptoms of confusion, agitation, paranoia and terror. An infected person may also display hydrophobia fear of water. In this seemingly bizarre condition the patient becomes panicked when given anything to drink.

The most likely reason is that rabies infects the salivary glands at the back of the mouth so it can be passed on in a bite. This infection also causes the muscles of the throat to go into excruciating spasm when salivation increases on presentation of a drink. Infection with rabies occurs when bitten or scratched by an infected animal — most commonly dogs or bats. Whilst there may be some flu-like symptoms after the bite the disease is generally without symptoms during an incubation phase.

This usually lasts for 1 to 3 months but can take years as the infection creeps through the nervous system towards the brain. Rabies is difficult to diagnose and unless suspected after a bite may well go undetected until neurological symptoms develop.

In fact only 5 people have ever survived rabies and the first was Jeanna Giese in She was treated with a new approach the Milwaukee protocol involving an induced coma and survived to make an almost full recovery. Fortunately a bite from a rabies infected animal is no longer a certain death sentence. There is also an equally effective vaccine.

The process activity is captured in the Process Tree, as well as in the Processes Created and Processes Terminated sections: Figure 2: Process tree, process created, and process terminated info in Microsoft Sysinternals report. For example, the dropped files are captured and registry keys are logged: Figure 4: Dropped files and registry modification info in Microsoft Sysinternals report.

Some of the shell commands clearly identify the threat as a coin miner: Figure 5: Shell commands info in Microsoft Sysinternals report. This new notebook lets researchers: Query and browse VirusTotal summary and detonation data for a given file hash.

Visualize detonation process trees with command lines. Generate sample queries for Azure Sentinel to search for indicators from the detonation data. It infected around systems in countries, most of which belonged to Russia Once installed, PseudoManuscrypt allows the attackers to take complete control of the infected system.

This includes disabling antivirus, recording keystrokes, capturing screenshots, stealing VPN data, extracting data from clipboards, and more. One hundred different versions of PseudoManuscrypt loader have already been identified, and to transfer data to command-and-control C2 servers, it uses code in Chinese.

For instance : Cybercriminals are sending emails that claim to be sent out by the official WHO and give tips to the users to stay protected from the endemic Coronavirus. Users who trust these emails fall prey to these tactics.

Therefore, if you receive any emails in the name of WHO, a vaccine for coronavirus, or any tips that will help cure COVID, then never trust such emails. They are sent to inject Emotet malware into your device.

Belonging to a popular Cryptomix Ransomware family, Clop is improving with time and causing major damages than ever before. There are tons of variants of Clop and their main goal is to encrypt all files in an enterprise and request huge ransom amounts to decrypt the infected files.

Clop Ransomware mostly targets Windows users. For instance: A dangerous file-encrypting virus that holds the potential to actively prevent the security of the system encrypting the saved files by planting the. CLOP extension file.

When this enters into your computer, it exploits AES Cipher to encrypt your data. For example: picture. Attacks that use social engineering tactics are designed to especially target human aspects.

For instance: A new Android banking trojan dubbed Gustuff is gaining popularity. The malicious computer virus targets cryptocurrency apps, known banks like Bank of America, Bank of Scotland, etc. Not only this, but Sim swapping attacks are also skyrocketing this Due to clever social engineering, bad actors gain access to the SIM card of the victim and trick the mobile carrier to think it is the real customer that is using the device. With the increase in the number of AI devices, hackers are also being inclined towards it.

For instance: The malicious computer virus is smart enough to figure out its way to target your devices. AI-enabled attacks have the potential to bypass almost all kinds of authentication methods and remain undetected. With time hackers are becoming technologically advanced, therefore to stay protected from a virus you need to maintain good digital hygiene. And organizations should start operating with AI-enabled defenses to counter AI-enabled attacks.

In recent years, IoT has gained popularity for its ease of use but at the same time, for its lack of built-in firewalls, it is surrounded by controversies. Most IoT devices fail to provide options to change the default username, thereby making devices an easy target for hackers.

A successful execution led to remote code execution, allowing bad actors to take complete access to devices. Due to this Therefore, if you have any plans to invest in an IoT device we suggest looking for safety measures.

Almost common security threats for IoT devices involve hijacking, leaks, home intrusions, etc. When exploited by the attacker these four remote codes and one denial service will allow threat actors to take full control over all the Cisco devices.

For instance: These vulnerabilities are named as CVE is a stack overflow vulnerability, CVE is a format string vulnerability, CVE is a stack overflow vulnerability in the parsing function, CVE is a heap overflow vulnerability in the Cisco series IP camera, and CVE the denial-of-service vulnerability.

Gameover is the latest computer virus in the Zeus Family. The malicious threat targets your device in a way to effortlessly access your bank account details and steals all your money. It simply creates its standalone server and accesses sensitive and confidential details of victims. This is why it is called AIDS. Being fully vaccinated for COVID can protect you from the delta variant, but breakthrough infections sometimes occur. All three of the F. For Pfizer and Moderna vaccines, you need both doses for maximum protection.

People should know that vaccines are very effective at preventing the most severe forms of COVID, but breakthrough infections can occur and caution is still warranted after becoming vaccinated. While the authorized COVID vaccines are not perfect, they are highly effective against serious coronavirus disease and reduce the risk of hospitalization and death.

Other vaccines available in other countries may not be as effective in protecting you from the delta variant and other mutations of the coronavirus. Although vaccines afford very high protection, infection with the delta and other variants remain possible. Fortunately, vaccination, even among those who acquire infections, appears to prevent serious illness, hospitalization and death from COVID How are the new coronavirus variants different?
