Child abuse images being traded via secure apps

Technology
Images of child sexual abuse and stolen credit card numbers are being openly traded on encrypted apps, a BBC investigation has found.Security experts told Radio 4's File on 4 programme that the encrypted apps were taking over from the dark web as a venue for crime.The secure messaging apps, including Telegram and Discord, have become popular following successful police operations against criminal markets operating on what is known as the dark web - a network that can only be accessed by special browsers.The secure apps have both a public and encrypted side. Often, the public side is listed online so users can search and join groups advertising drugs, stolen financial data and other illegal material. Once a group is joined, howeve...

Child abuse images hidden in crypto-currency blockchain

Technology
Images of child sexual abuse have been found embedded in the system powering a high-profile crypto-currency.Somebody added the illegal images to the core ledger of Bitcoin Satoshi Vision (BSV) by using a payment processor.This ledger, known as the blockchain, is a running record of crypto-currency transactions, shared among users of the platform.Experts have warned that abuse of blockchain tech is a growing problem.How did this happen?The blockchain is central to the way many crypto-currencies such as Bitcoin work and in theory stops people making fake transactions or manipulating their account balance.One key feature of the blockchain is that information added to it cannot be changed without significant effort. In January, the amount of data that could b...
Scientists use satellite images to measure household poverty

Scientists use satellite images to measure household poverty

Science
Jan. 7 (UPI) -- To more strategically allocate resources, set agenda priorities and track the progress of economic initiatives in the developing world, the United Nations is turning to satellite imagery. Researchers at Aarhus University in Denmark have developed methods for quantifying economic living conditions at the household level using high resolution satellite images. "Based on high-resolution satellite images, we can very precisely assess the status of poverty at household level in rural areas in developing countries," Jens-Christian Svenning, a professor and researcher at Aarhus, said in a news release. Using satellite images of portions of rural Kenya as a proof-of-concept test, scientists used several factors to estimate economic living conditions on local farms. Researchers ide...

Christmas card from Mars: Images of 82km-wide ice-filled crater

Technology
The European Space Agency's (ESA) Mars Express satellite has sent home spectacular Christmas card images from the Red Planet. The Korolev crater is an 82km-wide (50 mile) impact crater near the planet's north pole.It contains an estimated 2,200 cubic kilometres of water ice, frozen up to an estimated 2km (1.2 miles) deep.ESA's Mars Express mission launched back in 2003. It went into orbit around Mars on Christmas Day of that year, making this month the 15-year anniversary of the beginning of its science programme. The beautiful Christmas card image and two others are "an excellent celebration of such a milestone", according to ESA.They were taken by the Mars Express High Resolution Stereo Camera (HRSC) and the view they offer of the Korolev crater is composed of five di...

New images of 'hippo' asteroid as it zips past Earth

Technology
Earth is not on a collision course with a massive asteroid, detailed pictures of the nearby flying object have revealed. Astronomers have been in awe as it approached the planet and provided the opportunity to obtain radar images of the asteroid's surface and shape.NASA said the pictures would help observers understand the object's orbit.The asteroid, first discovered in 2003, is classified as "potentially hazardous" due to its size and close approaches to Earth's orbit.However, the latest radar measurements confirm it does not pose a future impact threat to Earth. 1:27 ...
