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.


Nasa finds Chandrayaan-2 lander Vikram with help of Indian engineer




New York: NASA has found the crash site and debris of India’s Chandrayaan-2 Vikram moon lander following a tip from an Indian space enthusiast who examined pictures of the area of the moon taken by a US orbiting camera.

The site was located by Shanmuga Subramanian, who on his own scoured the pictures taken by the Lunar Reconnaissance Orbital Camera (LROC), NASA and Arizona State University announced on Monday confirming the find.

The first mosaic image of the likely crash site made from pictures taken by the LROC on September 17 was downloaded by several people to look for signs of the Vikram, NASA said.

One of them, Subramanian, contacted the LROC project with a positive identification of debris, it said.

Arizona State University (ASU), where the LROC project is located, said: “After receiving this tip, the LROC team confirmed the identification by comparing before and after images.”

When the images for the first mosaic were acquired on September 17, the impact point was poorly illuminated and could not easily be identified, it said.

But two image sequences were acquired on October 14 and 15, and on November 11 were better.

The November mosaic shows best the impact crater, ray and extensive debris field. The three largest pieces of debris are each about 2×2 pixels and cast a one pixel shadow.

The university said that based on Subramanian’s tip, the LROC team scoured the surrounding area in the new mosaics and found the impact site and the debris field.

The impact site is located at 70.8810 degree S, 22.7840 degrees E, at an elevation of 834 metres, it said.

“The debris first located by Shanmuga is about 750 metres northwest of the main crash site,” ASU said.

Vikram lost contact with the Indian Space Research Organisation (ISRO) following its launch from Chandraayan-2 moon orbiter on September 6 when it tried to make a softlanding near the moon’s south pole.

In a statement NASA said: “Despite the loss, getting that close to the surface was an amazing achievement.”
