A yellow fever vaccine has been mandatory since 2002 for any Brazilian born in regions where the virus is endemic. On January 25, Brazilian health officials launched a mass campaign to vaccinate 95 percent of residents in the 69 municipalities directly in the disease’s path-a total of 23 million people. But as the country’s health authorities scramble to contain the worst outbreak in decades, WhatsApp’s misinformation trade threatens to go from destabilizing to deadly. With its modest data requirements, WhatsApp is especially popular among middle and lower income individuals there, many of whom rely on it as their primary news consumption platform. The platform has long incubated and proliferated fake news, in Brazil in particular. In recent weeks, rumors of fatal vaccine reactions, mercury preservatives, and government conspiracies have surfaced with alarming speed on the Facebook-owned encrypted messaging service, which is used by 120 million of Brazil’s roughly 200 million residents. And nowhere is it happening faster than on WhatsApp. The only thing spreading faster is misinformation about the dangers of a yellow fever vaccine-the very thing that could halt the virus’s advance. Today, that pestilence is racing toward Rio de Janeiro and Sao Paulo at the rate of more than a mile a day, turning Brazil’s coastal megacities into mega-ticking-timebombs. The mosquito-borne virus attacks the liver, causing its signature jaundice and internal hemorrhaging (the Mayans called it xekik, or “blood vomit”). Yellow fever began expanding south, even through the winter months, infecting more than 1,500 people and killing nearly 500. But in 2016, perhaps driven by climate change or deforestation or both, the deadly virus broke its pattern. Every six to ten years, during the hot season, mosquitoes would pick it up from infected monkeys and spread it to a few loggers, hunters, and farmers at the forests’ edges in the northwestern part of the country. Luckily, WhatsApp now gives its users control over who can view their statuses but if your contact list is huge then it becomes a task to pick and choose a person you want to share or not share your status.In remote areas of Brazil’s Amazon basin, yellow fever used to be a rare, if regular visitor. Any person in your contact list can view your status. However, WhatsApp is all about your phone contacts and not all of them are your friends and family members. WhatsApp status isn't private: The Status feature on WhatsApp has been directly lifted from the one found on Instagram. The Facebook-owned company has come up with several measures to curb this menace but has still fallen short of completely curbing it. WhatsApp was caught up in the midst of several incidences of violence that occurred in India during 20. The Media File Jacking threat is especially concerning in light of the common perception that the new generation of IM apps is immune to content manipulation and privacy risks, thanks to the utilisation of security mechanisms such as end-to-end encryption.įraud and fake news: In India, WhatsApp has come under the government's scanner for spreading fake news and misinformation.

The vulnerability stemmed from how media files are stored in WhatsApp. Hacker can alter photos and videos: A security flaw in WhatsApp has come to light that allows potential hackers to alter the image, audio or video files. WhatsApp had recently signed a pact with Google to allow its users to store messages on the search giants' cloud storage offering. However, that encryption does not work if the data is stored as a backup on Google Drive. The best way to avoid such malware is to use apps and services only from the official sources.īackup messages are not encrypted: WhatsApp has made loud noises about end-to-end encryption that ensures that only you and the person you're communicating with can read what's sent. This is just one of the possible ways the malware can use the affected device to send money back to the hackers, as per a typical pay-per-click system. The malware is capable of hiding its icon from the phone's launcher and can pose as WhatsApp to serve advertisements.
