What is Pegasus Spyware?

Today we are living in a digitally advanced era but no one can neglect the fact that over the years the incidents of cyber‐attacks like phishing, vishing and malware attacks including trojans, spyware, etc. are increasing exponentially and in fact, they became menace in some of the cases. You would have heard about the Pegasus spyware which has become very popular term recently. Do you know about it? If you don’t know yet then no worries because here in this article, we are going to talk about the key aspects of the Pegasus spyware. But before that, we must know what a spyware is? Spyware is a malware or a software with malicious behavior that is designed to enter your computer device in order to damage your system or steal the sensitive data and send it to the third party without your consent. What is a Pegasus spyware? It is a spyware developed by the Israeli NSO Group which can be covertly installed on mobile phone running most versions of iOS and Android and is probably the most powerful spyware developed till date. It was in the August of 2016 when the news of the Pegasus took significant coverage for the first time when an Arab activist got sophisticated after getting a shady message. This was the most sophisticated smartphone attack ever. Several days after it was discovered, Apple had updated its version of iOS, which patched the security loopholes that was used for hacking. This version of Pegasus used spear‐phishing‐ emails or messages containing a malicious links were sent to the target. In July 2021, Amnesty International (human rights group) revealed that Pegasus was still being used against the high‐profile targets like government officials, journalists. This time Pegasus was able to infect all modern iOS versions up to iOS 14.6 through zero‐click, which requires no action from the victim’s end‐ means even the most advanced user can be the victim to unprecedented cyber‐attacks. A zero‐click attack exploits a flaw or bug in the device you are using‐ be it Android or iOS, and Windows or macOS, which makes use of a data verification loopholes (about which the manufacturerdoesn’t even know yet and hence has not been able to fix) to work in your system. In 2019, WhatsApp revealed that software made by the NSO was being used to send the malware to more than 14,000 phones by exploiting a zero‐day vulnerability, triggered by a WhatsApp call. The malicious Pegasus code could be installed in the system even if the target didn’t answer the call. The missed call trick exploited a flaw in the source code frame work of the WhatsApp and this allowed the hacker to load the spyware in the data exchange caused between two devices due to the missed call. Once loaded, the spyware would automatically enable itself as a background resource, embedded deep inside your device’s software framework. Also read : cyber‐attacks Important points: It works according to the zero‐click. The target need not to give any input to make the malware work, it only takes a missed call, message, or iMessage for initiation. And after entering the device, it completes the task. Once a Pegasus spyware is installed in someone’s phone, it attacks the device so seamlessly that even is almost impossible for the user to detect whether they have been hacked, making it even more dangerous. It is self‐destructing in nature. For example‐ Suppose the spyware was installed in your device for let’s say one week’s time then after the completion of task in its scheduled time, it will be self‐destroyed. And even if it is not able to communicate to its command center, then it automatically settles. It provides complete access. It can do more than what you can do on your device. When your system is compromised, it is done in such a way that allows the attacker to obtain the root privileges on the device. It can start your device’s mic or camera anytime. Can you be the next victim? NSO has created the Pegasus Spyware to help government, law enforcement agencies prevent and investigate terrorism and crime to save the lives across the globe and not for mass surveillance. Also, this is very expensive, it carries a high price tag averaging at over $25,000 per target, so practically it is not feasible for the government agencies to use it without any justified reason. And a normal person needs a license for it and the process for buying it is also very complicated. So, you can consider yourself safe.Also, Apple itself has called such attacks “highly sophisticated, cost millions of dollars to develop, often have a short shelf life, and are used to target specific individuals”. How to Prevent Spyware? We can keep in mind the below‐mentioned points to prevent ourself from spywares Keep your software and other apps on your device updated because if there would be any vulnerability in it then it will be updated immediately. Also, outdated software is vulnerable to hackers and cyber criminals. Do not use public WIFI services as hackers can use an unsecured Wi‐Fi connection to distribute malware. Sharing any file across the network allows hackers to easily plant the infected software on your system. Do not install the applications from unknown sources as you don’t have any idea what is getting in your device. Allow it only when you know hat it will do to your device. Only open those messages or links which are sent by your trusted contacts. I am not saying that following the above points will make you completely safe from spywares – but of course it will reduce the risk to a great extent! CONCLUSION: The Pegasus spyware, developed by the NSO group has targeted globally more than 50,000 phone numbers for surveillance. How many more people will be targeted and who will be targeted we don’t know. For the time, it can be said that if you are a normal person then you are probably safe to

Black fungus infection Symptoms, History, Treatment, Complications and Prevention.

BLACK FUNGUS Mucormycosis is commonly known by the of Black fungus, it was previously known as zygomycosis because it has characters similar to the class zygomycetes of kingdom fungi such as cell wall made up of chitin, method of asexual reproduction, gametangial copulation, diploid and multinucleated(coenocytic) body and unbranched mycelium (a group of hyphae). Some of the members of class zygomycetes are Rhizopus, mucor/pinmold, that’s why the disease is named as mucormycosis. As the name of the disease is revealing, it is a fungal infection caused by the fungi called mucormycetes. It belongs to the kingdom: fungi, phylum: Mucoromycota, order: Mucorales, family: Mucoraceae and genus: Mucor. https://foxfoster.com/wp-content/uploads/2021/06/Virus-66101-1.mp4 HISTORY OF BLACK FUNGUS :- The very first case of the mucormycosis was reported in the year 1855. Later on, the disease was reported to be found in lungs in the year 1876 by Furbringer. After several researches and studies, it was in the year 1943, the disease was reported in three cases including severe sinus, brain and eye involvement in association with the diabetes. Afterwards, the disease had been reported during natural disasters. Until the half of the 20th century, the disease was treated using potassium iodide. The survival was better in those who were getting medical treatment along with the surgery. It affects less than 1.7 per million population each year. It is rare but is 80 times more widespread in India. CAUSE OF BLACK FUNGUS: The fungal infection is caused by the fungi called Mucormycetes. The maximum number of cases is due to the Rhizopus and Mucor. We can come in contact with this while eating contaminated food, touching the articles responsible for the development of fungus like soil or by inhalation of the mold spore or a group of molds known as mucormycosis. It can also enter through the cuts or wounds present on the skin and may also be present in the decomposed organic matters like manure, rotten fruits and vegetables. Who may be the next victim? Everyday we are exposed to large number of infectious diseases. But, only a few of them get exposure to the disease. Why? It’s because of the fact that our body is able to defend itself from most of the foreign agents and this overall ability of the host to fight the disease‐ causing organisms, conferred by the immune system is called immunity. Persons having less immunity or you can say one with weak immune system may be at risk or those having the health condition like diabetes, cancer, etc. Mainly the COVID‐19 patients are fighting severe condition of mucormycosis due to their less ability to fight from the disease. According to the reports, there were 7,250 infected, 219 deaths in India due to the Black fungus as on 21st May, 2021 and the graph is increasing day by day. Patients taking immunosuppressant medications or one with comorbidities to fight off the pathogens are more prone to this fungal infection. SYMPTOMS OF BLACK FUNGUS: ‐ The infection generally begins with the nose or mouth and then reaches the central nervous system through the eyes. It is not a contagious disease. The symptoms mainly depend upon the site of infection including fever, headache or one‐sided eye pain, cough, runny nose, loss of smell, shortness of breath, diarrhea, blood in stool, tummy ache, vomiting, nausea, blood clot inside a blood vessel, swelling on one side of the face, sinus congestion, bleeding from the gastrointestinal tract, chest pain, one eye may look bulging out and swollen, vision may also be blurred. Severe infection occurs in those with serious medical condition like cancer, AIDS or HIV, diabetes (not under control), organ transplant, use of steroid in the long term, addiction of drug, poor nutrition, etc. Depending upon the site of infection mucormycosis is classified into six types: ‐ Lungs (pulmonary): ‐ Mainly in people with cancer or an organ transplant. Sinuses and brain (rhinocerebral): ‐ Commonly in those with high diabetes or one with a history of kidney transplant. Stomach and intestine (gastrointestinal): ‐ Mostly among premature and low birth weight infants having less ability to fight infection. Skin (cutaneous): ‐ Generally in people with leukaemia (is a group of blood cancer that usually begins in the bone marrow), HIV, high diabetesor one who uses drug injection. Widespread: ‐ spread of infection to other parts or organs of body through the blood. Less commonly affected parts. Diagnosis and Treatment of Black Fungus: ‐ Diagnosis is by biopsy (a medical test commonly performed by the surgeon to examine the extent or presence of a particular disease). The doctor will ask your medical history and you will be examined physically or MRI, CT scans can be conducted to know which organ or tissue is infected by the fungus. If you have a history of sinus, then doctor will take a sample of fluid from your nose or throat and based upon it, your treatment will be started. The treatment is mainly done with Amphotericin B. Amphotericin B is given in the vein for the first 14 days, and afterwards if the patient is recovered then is treated with pills but if the patient is not recovered then Amphotericin B is continued for some more days. In case, it becomes very serious then the doctor may recommend you a surgical debridement (surgery for removing the infected tissue to improve the healing potential) in order to stop the fungus from spreading to other parts of the body. Complications of black fungus: ‐ According to the researchers, 56% people die with mucormycosis. But it depends on the organ or part which is affected. In severe cases it may lead to blindness, nerve damage, blood clots. Due to the blood clot inside a blood vessel, there is a loss of blood supply to the surrounding tissues leading to the death of these tissues. The infection can be spread to the other parts or organs of your body through the blood which results in direct attack of the fungus to the vital
