Indian WhatsApp users must beware what they share



New Delhi: Security hacks are on a rise. Malicious hackers are actively looking for flaws and vulnerabilities in tech platforms, particularly social media apps that would allow them to gain control of users’ personal profiles and use them to their advantage. At a time when cyber-attacks are on a rise Facebook is yet to fix three flaws in its social messaging app, WhatsApp, that can allow hackers to edit users’ sent messages.

During the annual Black Hat security conference that was held in Las Vegas, United States earlier this week security researchers from an Israeli cyber security firm Check Point demonstrated how malicious hackers can use vulnerabilities in WhatsApp’s platform to manipulate the contents of not only the messages sent in a personal chat but also in a group chat.

In a blog post, Check Point researchers Dikla Barda, Roman Zaikin and Oded Vanunu explained the three vulnerabilities plaguing the popular social messaging platform. The first vulnerability allows hackers to use the “‘quote’ feature in a group conversation to change the identity of the sender, even if that person is not a member of the group.” The second vulnerability, as the researchers explained, allows hackers to “alter the text of someone else’s reply, essentially putting words in their mouth.”

The third flaw, allows the malicious hackers to “send private messages to another group participants that is disguised as a public message for all.” This means that you might feel that you have received a private message in a group, but it will be visible to all the people in the group.


Link medical facilities with virtual ICUs: Yogi




UP Chief Minister Yogi Adityanath has asked officials to start the process to link medical institutes with virtual ICUs by using technology in such a way that the serious patients may get treatment from experienced doctors.

He also asked the officials to keep ventilators/high flow nasal cannula (HFNC) functional in all districts.

At a meeting of Team 11, the Chief Minister has directed officials to adopt an effective strategy to control spread of Coronavirus in districts where 100 or more positive cases are being found every day for the last one week.

He asked the Chief Secretary, Additional Chief Secretaries of Home (health and medical education) along with medical experts to hold a detailed discussion to finalise the action plan in this regard.

The Chief Minister reiterated that nodal officers be nominated in these districts with deployment of special secretary-rank officers with each of nodal officer.

Yogi also asked officials to maximise contact tracing for effective control on Corona infection. He asked them to target high risk groups and put them to tests.

He stressed on taking up enforcement exercise to check observance of social distancing and use of masks by people.

“Create micro-containment zones as and where required. Public address systems should be functional all the time to spread awareness about protection from Corona virus and the prevailing traffic rules,” he said.

He said one-third of the total Covid tests per day should be conducted through RT-PCR and the rest by rapid antigen method.

He further directed officials to increase the number of beds in Covid Level-2 and Level-3 hospitals.

The Chief Minister said that the people should be sensitized about protection from Covid-19 in view of coming festivals. He said the festivals had to be celebrated at home and no public functions should be organised and all the norms of social distancing and use of masks should be followed strictly.
