Immediately after spyware-maker Connexxa’s infamous app “Assistenza SIM” was caught abusing the iOS enterprise certificate to bypass Apples App Store guidelines, the iPhone-maker revoked its enterprise certificate, making it un-installable on iOS devices.

Security researchers at the US-based IT security company, Lookout, revealed that the app could steal contacts, videos, photos, real-time location data from users’ devices and tap their phone calls as well, The Verge reported on Monday.


The iOS enterprise certificate, that is meant “solely for the internal distribution of apps within an organisation” otherwise, allowed the “Assistenza” app to bypass the Apple certification and stay accessible for downloads through phishing sites outside the App Store.

Details on exactly how many users were targeted by the app and how much information was accessed remain undisclosed.

In 2018, the app was discovered on Android with root access to the smartphones of several users.

Before the app was brought into Google’s notice and removed from PlayStore, the spyware developers could read Wi-Fi passwords, emails as well as data from apps like Facebook, Gmail, WhatsApp, Viber and WeChat.

All this time, the developers have been disguising the app to pretend to be the carrier of helpline apps from Italian and Turkmenistani mobile operators, which could help users get in touch with them.

Raising questions on Apple’s pride over its security measures and App Store policies, a bunch illicit apps that use enterprise certificates offer pirated content, porn, gambling and all kinds of materials.

Recently, Facebook gathered Apple’s attention when it began paying people to install a “Facebook Research” Virtual Private Network, which collected the user’s private phone and web data without their consent.

Google was also found to have been running a similar programme and in response, Apple briefly revoked the certificate used by Google and Facebook to push updates on their apps, the report added. (IANS)

Indian astronomers have found an active galaxy in a very bright state with 10 times more X-ray emission than normal

Indian astronomers have found an active galaxy in a very bright state with 10 times more X-ray emission than normal, equivalent to more than 10 trillion of the sun, and located five billion light years away that could help probe how particles behave under intense gravity and acceleration to the speed of light.

It could help study the role of strong gravity and acceleration of matter in the formation, interaction and evolution of galaxies in the early universe.

Every galaxy in the universe is believed to host a supermassive black hole at its centre. In some galaxies, the black hole is actively devouring a large amount of material and shooting a jet of plasma almost at the speed of light towards us. These are called blazars.

OJ 287 belongs to a class of blazars known as BL Lacertae objects which show very rapid and large amplitude flux variations but barely discernible emission line features.

This class of sources emit in the whole electromagnetic spectrum, a rather uncommon phenomenon which requires extreme physical conditions. Hence, a study of such sources tells us about the behaviour of matter in an extreme gravitational field where it is difficult for light to escape from the vicinity of the black hole.

Astronomers at Aryabhatta Research Institute of Observational Sciences, an autonomous institute of the Department of Science and Technology, Government of India, have been monitoring one such black hole system named 'OJ 287' since 2015. This source shows a repeated optical brightness enhancement almost every 12 years.

"The repeated optical enhancement makes OJ 287 very intriguing as this class of sources does not show any repeating features in flux variations. The repeated optical enhancement made the researchers believe that the system hosts a binary black hole," said a release from the Ministry of Science and Technology.

In 2020, the source was very bright at optical and X-ray bands with X-ray flux more than 10 times the normal (non-active phase) flux. This flare was very different as it was not expected in models proposed for this source and thus, indicated a more complex system and physical conditions.

Investigating the extreme brightness shown by OJ 287 at optical and X-ray bands, astronomers led by Pankaj Kushwaha and Alok C. Gupta reported the source in a completely new spectral state.

The team argued that this change of state holds clues to the researcher's quest to understand how matter behaves in very strong gravity and how it accelerates the particle to almost the speed of light -- a feat that is out of the scope of even the most advanced CERN accelerator.

The research published in 'The Astrophysical Journal' tracked the details of changes in optical to the X-ray emission spectrum of the source with time from 2017 to 2020 -- after the second brightest X-ray flare of the source. It revealed how the source gradually started to change its spectral behaviour from mid-2018 to the new spectral state in 2020.

The study included data recorded by the ground-based facility operated by Physical Research Laboratory, Ahmedabad, operated Mount Abu observing facility in near infra-red bands and the space-based NASA's satellites -- the Niels Gherel Swift satellite at optical, UV and X-rays with gamma ray data from the Fermi satellite, the release added.

Tospread awareness about the significance of reading, Rachna Kalra, who hails from Gurugram (Haryana), started the Silent Book Club in the year 2019.

Who doesn't like reading, and that, too, reading along the company of mother nature? Well, this book club is truly a fantasy turned to reality.

As said by a regular reader at the Silent Book Club, “There is something meditative about reading. Sitting quietly with a book, without any distractions, is almost spiritual for me," this exactly is the case with many such readers.
