New Linux Trojan Can Spy on Users by Taking Screenshots and Recording Audio

An anonymous reader writes: Dr.Web, a Russian antivirus maker, has detected a new threat against Linux users: the Linux.Ekoms.1 trojan. It includes functionality that allows it to take screenshots and record audio. While the screenshot activity is working just fine, Dr.Web says the trojan’s audio recording feature has not been turned on, despite being included in the malware’s source code. “All information transmitted between the server and Linux.Ekoms.1 is encrypted. The encryption is initially performed using the public key; and the decryption is executed by implementing the RSA_public_decrypt function to the received data. The Trojan exchanges data with the server using AbNetworkMessage.” Read more of this story at Slashdot.

LastPass Vulnerable To Extremely Simple Phishing Attack

An anonymous reader writes: Security researcher Sean Cassidy has developed a fairly trivial attack on the LastPass password management service that allows attackers an easy method for collecting the victim’s master password. He developed a tool called LostPass that automates phishing attacks against LastPass, and even allows attackers to collect password vaults from the LastPass API. Read more of this story at Slashdot.

Cryptsy Bitcoin Trader Robbed, Blames Backdoor In the Code of a Wallet

An anonymous reader writes: Cryptsy, a website for trading Bitcoin, Litecoin, and other smaller crypto-currencies, announced a security incident, accusing the developer of Lucky7Coin of stealing 13, 000 Bitcoin and 300, 000 Litecoin, which at today’s rate stands more than $5.7 million / €5.2 million. Cryptsy says “the developer of Lucky7Coin had placed an IRC backdoor into the code of [a] wallet, which allowed it to act as a sort of a Trojan, or command and control unit.” Coincidentally this also explains why two days after the attack was carried out, exactly 300, 000 Litecoin were dumped on the BTC-e exchange, driving Litecoin price down from $9.5 to $2.

Grisly Find Suggests Humans Inhabited Arctic 45,000 Years Ago

sciencehabit points out this story which may rewrite the early history of humans in North America. From the Sciencemag story: “In August of 2012, an 11-year-old boy made a gruesome discovery in a frozen bluff overlooking the Arctic Ocean. While exploring the foggy coast of Yenisei Bay, about 2000 kilometers south of the North Pole, he came upon the leg bones of a woolly mammoth eroding out of frozen sediments. Scientists excavating the well-preserved creature determined that it had been killed by humans: Its eye sockets, ribs, and jaw had been battered, apparently by spears, and one spear-point had left a dent in its cheekbone—perhaps a missed blow aimed at the base of its trunk. When they dated the remains, the researchers got another surprise: The mammoth died 45, 000 years ago. That means that humans lived in the Arctic more than 10, 000 years earlier than scientists believed, according to a new study. The find suggests that even at this early stage, humans were traversing the most frigid parts of the globe and had the adaptive ability to migrate almost everywhere.” Read more of this story at Slashdot.

EU Companies Can Monitor Employees’ Private Conversations While At Work

An anonymous reader writes: A recent ruling of the European Court of Human Rights has granted EU companies the right to monitor and log private conversations that employees have at work while using the employer’s devices. The ruling came after a Romanian was fired for using Yahoo Messenger back in 2007, while at work, to have private conversations with his girlfriend. He argued that his employer was breaking his right for privacy and correspondence. Both Romanian and European courts disagreed. Read more of this story at Slashdot.

Graphene Flakes Facilitate Neuromorphic Chips

An anonymous reader writes: One of the hot areas of semiconductor research right now is the creation of so-called neuromorphic chips — processors whose transistors are networked in such a way to imitate how neurons interact. “One way of building such transistors is to construct them of lasers that rely on an encoding approach called “spiking.” Depending on the input, the laser will either provide a brief spike in its output of photons or not respond at all. Instead of using the on or off state of the transistor to represent the 1s and 0s of digital data, these neural transistors rely on the time intervals between spikes.” Now, research published in Nature Scientific Reports has shown how to stabilize these laser spikes, so that they’re responsive at picosecond intervals. “The team achieved this by placing a tiny piece of graphene inside a semiconductor laser. The graphene acts as a ‘saturable absorber, ‘ soaking up photons and then emitting them in a quick burst. Graphene, it turns out, makes a good saturable absorber because it can take up and release a lot of photons extremely fast, and it works at any wavelength; so lasers emitting different colors could be used simultaneously, without interfering with each other—speeding processing.” Read more of this story at Slashdot.

BBC Confirms 50% Bitrate Savings For H.265/HEVC Vs H.264/AVC

An anonymous reader writes: A research team from the BBC has done a series of tests to confirm earlier computations showing a ~50% savings in bit rate for H.265/HEVC compared to video using H.264/AVC at comparable quality. “The subjective tests used a carefully selected set of coded video sequences at four different picture sizes: UHD (3840×2160 and 4096×2048), 1080p (1920×1080), 720p (1280×720) and 480p (832×480), at frame rates of 30Hz, 50Hz, or 60Hz. The video content was chosen to represent diverse spatial and temporal characteristics, and then coded using HEVC and AVC standards at a wide span of bit rates producing a variety of quality levels.” Here is the full published analysis. “The tests confirmed the significant compression efficiency improvements achieved in HEVC, verifying the results previously reported using objective quality metrics (PSNR based methods).” The team did not test against VP9, which is shaping up to be an impressive standard as well.

How We Know North Korea Didn’t Detonate a Hydrogen Bomb

StartsWithABang writes: The news has been aflame with reports that North Korea detonated a hydrogen bomb on January 6th, greatly expanding its nuclear capabilities with their fourth nuclear test and the potential to carry out a devastating strike against either South Korea or, if they’re more ambitious, the United States. The physics of what a nuclear explosion actually does and how that signal propagates through the air, oceans and ground, however, can tell us whether this was truly a nuclear detonation at all, and if so, whether it was fusion or fission. From all the data we’ve collected, this appears to be nothing new: just a run-of-the-mill fission bomb, with the rest being a sensationalized claim. (Related: Yesterday’s post about how seismic data also points to a conventional nuke, rather than an H-bomb.) Read more of this story at Slashdot.

Tesla Model S Software Updates Lets Car Park Itself With No One Inside It

An anonymous reader writes with a lnk to this article at Boy Genius Report about a software upgrade now hitting Tesla owners, which begins: Tesla earlier today began pushing out version 7.1 of its software to Model S and Model X owners and, suffice it to say, it’s a doozy of a software update. While we’ll get to the full changelog shortly, we first wanted to highlight a feature called Summon which enables users to park their cars without having to be inside it. Conversely, it also lets Tesla owners summon their cars that already happen to be parked. Read more of this story at Slashdot.

New Dell Tech Support Scams Have Customers Worried Company Was Hacked

Trailrunner7 writes: A new twist on the fake tech support scam has arisen that has victims wondering whether Dell has been hacked.There has been a recent rash of calls to Dell customers in which the caller says he is from Dell itself and is able to identify the victim’s PC by model number and provide details of previous warranty and support interactions with the company. These are details that, it would seem, only Dell or perhaps its contractors would know. One person who was contacted by the scammers wrote a detailed description of the call, and said the caller had personal details that could not have been found online. Dell officials say they’re looking into it. Read more of this story at Slashdot.
