Pirated streaming devices are filled with malware researchers find

first_img $179 Mentioned Above Apple TV 4K (32GB) CNET may get a commission from retail offers. 1:49 $169 Comments See It Best Buy If you have a bootleg streaming device, chances are it’s filled with malware, researchers found. Sarah Tew/CNET It seems there’s no such thing as a free show.Security researchers from the Digital Citizens Alliance (DCA) and Dark Wolfe Consulting looked into six streaming devices that offered free shows through pirated apps and found nearly half of them were packed with malware. While you may have bought a bona fide Apple TV or Roku to watch shows on Netflix or Hulu, there’s an entire market online for jailbroken and modified devices that are tuned to watch this same content for free. They come at a much cheaper price and offer free, unlimited access to shows that you’d normally have to pay a subscription fee for. These devices work just like a Roku or a Fire TV Stick — you plug it into your TV and connect it to your Wi-Fi network. In some cases, they’re loaded with apps. 7 Now playing: Watch this: The DCA and Dark Wolfe found that there were 12 million active users in the US with these devices, meaning that millions of people are exposed to malware packed with these free shows, according to a report DCA published Thursday. “You have a choice, you can either have free movies, or your bank account,” said Tom Galvin, the DCA’s executive director. “When you bring one of these into your home, you’ve escorted a hacker past your security.”  One app for pirated movies and live sports, called Mobdro, immediately forwarded his Wi-Fi network name and password to servers in Indonesia, he said. Other apps would collect data on the user, including photos and videos on the network, and upload them to the server. In one case, an app collected more than a terabyte of data after getting connected to Wolfe’s network. These apps offered streams on movies that were still in theaters during the study time, like Aquaman and Green Book, as well as access to pay-per-views like UFC fights. One app, called “Free Netflix,” used a network of stolen Netflix accounts that would constantly rotate so that hacked users would not become suspicious, Wolfe said.In the background, these apps were scanning victims’ networks, looking for open ports to infect other devices, he said. “Once you start using these rogue apps, nothing is free, there’s always some angle to them,” Wolfe said. In one case, when the DCA arranged to buy one of the devices off Craigslist, the seller came out of the Department of Labor building in Washington, DC, to hand off the goods. On hacker forums, the researchers found that criminals online were discussing ways to exploit this malware. “Streaming is where consumers go to for their home entertainment, which means hackers and criminals are now targeting streaming as a place to exploit consumers,” Galvin said.  $179 Apple See itcenter_img See It Crutchfield Tags If the hardware isn’t laced with malware, the apps are, Timber Wolfe, a principal at Dark Wolfe Consulting, found in his research. He said 40% of apps for these devices were infected with malware that can take over a camera or microphone on the network within the first hour.As viewers move to streaming devices to watch shows, like Apple TVs, Rokus, Chromecasts and Fire TVs, black market sellers have capitalized on cordcutters by offering pirated alternatives. Cybercriminals have taken notice, by targeting these bootleg boxes with malware, researchers found. On April 8, the FCC issued an enforcement advisory warning that they were fining up to $19,639 per day for people selling these illegal streaming boxes, as well as people using them. While they aren’t in stores, you can still find them in popular sites like eBay, Craigslist and Facebook Marketplace. They’re also often sold at flea markets and malls for about $75 to $100. People are enticed to buy them because they promise free streams on sports, live shows and new movies. Once you start using these rogue apps, nothing is free, there’s always some angle to them.

SheriffElect Ed Gonzalez Wants To End Program That Leads To Deportations

SheriffElect Ed Gonzalez Wants To End Program That Leads To Deportations

I think the intent of the program is just to help assist the federal government in enforcement of immigration laws,” Chmielenski says.So, what do two top politicians in greater Houston think about eliminating the 287(g)?Harris County Judge Ed Emmett says he didn’t follow “any of the political campaign so, no, I have no comment.”And Houston Mayor Sylvester Turner comments he will leave that “concern” to the County.Doing away with the program could mean trouble for Harris County because Patrick says eliminating sanctuary cities is one of his priorities for the upcoming session of the Texas Legislature.Republican State Senator Charles Perry has already introduced a bill which requires that city and county jails cooperate with immigration authorities and, if it becomes law, the State could deny funding for those that don’t comply.An example of that funding is the one that pays for some law enforcement programs, according to a person familiar with the bill.Gonzalez acknowledges he is concerned about possible punishment by the State if he eliminates the 287(g), but he hopes things will not come to that because of the political negotiations in Austin.“There’ll be strong dialogue on both sides of it,” Gonzalez notes “and I hope that we could move away from regressive type of policies that are impactful, especially to one large segment of the community, which is the Latino community in this case.”Gonzalez takes office next January. 00:00 /02:26 Sharelast_img read more

Synthesis and characterization of an important intermediate for biocatalysts

Synthesis and characterization of an important intermediate for biocatalysts

Credit: Wikipedia/CC BY-SA 3.0 (Phys.org)—Cytochrome P450 (CYP) is sometimes referred to as the “Rosetta Stone” of iron-containing oxygenases, because of its ubiquity as a biocatalyst for various reactions, including drug metabolism and synthesis of biological molecules. Importantly, CYP catalyzes carbon-hydrogen hydroxylation reactions, cleaving some of the most difficult carbon-hydrogen bonding structures. While CYP is well studied, scientists are eager to understand the ferryl intermediates formed during hydroxylation in an effort to fine-tune catalytic reactions as well as seek out other biocatalysts to react with carbon-hydrogen bonds that are typically unreactive. Apolipoprotein(a): A natural regulator of inflammation More information: “Heme-thiolate ferryl of aromatic peroxygenase is basic and reactive” Xiaoshi Wang, Rene Ullrich, Marticn Hofrichter, and John T. Groves, www.pnas.org/cgi/doi/10.1073/pnas.1503340112AbstractA kinetic and spectroscopic characterization of the ferryl intermediate (APO-II) from APO, the heme-thiolate peroxygenase from Agrocybe aegerita, is described. APO-II was generated by reaction of the ferric enzyme with metachloroperoxybenzoic acid in the presence of nitroxyl radicals and detected with the use of rapid-mixing stopped-flow UV-visible (UV-vis) spectroscopy. The nitroxyl radicals served as selective reductants of APO-I, reacting only slowly with APO-II. APO-II displayed a split Soret UV-vis spectrum (370 nm and 428 nm) characteristic of thiolate ligation. Rapid-mixing, pH-jump spectrophotometry revealed a basic pKa of 10.0 for the FeIV−O−H of APO-II, indicating that APO-II is protonated under typical turnover conditions. Kinetic characterization showed that APO-II is unusually reactive toward a panel of benzylic C−H and phenolic substrates, with second-order rate constants for C−H and O−H bond scission in the range of 10–107 M−1⋅s−1. Our results demonstrate the important role of the axial cysteine ligand in increasing the proton affinity of the ferryl oxygen of APO intermediates, thus providing additional driving force for C−H and O−H bond scission.center_img This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Researchers have recently found that aromatic peroxygenases (APO), a fungus-based heme thiolate protein, can catalyze the oxygenation of aliphatic and aromatic hydrocarbons. Based on the products from these reactions, APO seems to behave similarly to CYP, although it apparently is more stable over a larger range of pH. This provides an opportunity to study the hydroxylation reaction mechanism of an analogous molecule to CYP that could serve as another potential biocatalyst. Xiaoshi Wang and John T. Groves from the Department of Chemistry at Princeton University report the isolation and characterization of APO-II, an important intermediate in hydroxylation, in the Proceedings of the National Academy of Sciences.Previous work by Groves’ group has shown that APO, derived from Agrocybe aegerita forms an oxoiron (IV) porphyrin radical cation (APO-I) that can be detected by UV-visible spectroscopy. The current work, isolates APO-II, a reduced form of APO-I. APO has an OH2 group coordinated to the central iron atom. Oxidation, using mCPBA yields an oxidized, Fe=O, interaction. Wang and Groves sought to isolate APO-II, which has an OH group coordinated to iron, via a one electron reduction reaction.Wang and Groves began by oxidizing APO using mCPBA, and then determined that the reduction of APO-I using a nitroxyl radical would provide APO-II. They tested their nitroxyl radical candidates using a model system, ensuring that they would get complete conversion from the oxidized to the reduced intermediate, and landed on 3-carboxy-PROXYL as the best reducing agent.UV-visible spectroscopy confirmed that they made APO-II using a single-mixing stopped flow experiment. They were also able to confirm that APO-II was formed via the direct reduction of APO-I using a double-mixing step. Kinetic studies indicated that APO-II remained in solution for 0.5 seconds and has an approximate decay rate of 1 sec-1, making it an intermediate that is stable enough to allow for further study.Because APO is stable at a wide range of pH values, pH 7.0 to pH 12, Wang and Groves were able to determine the pKa value of the proton on the hydroxyl group of APO-II using titration with buffer solutions and characterization with UV-visible spectroscopy. They found that the pKa for the hydroxyl proton was approximately 10, indicating that the molecule was protonated at a pH below 10. They also determined that the sulfur remained bound to the iron upon deprotonation at high pH.Finally, Wang and Groves investigated the reactivity of various substrates in an APO-II catalyzed hydroxylation reaction. They found that APO-II has a surprisingly high reactivity toward phenols and substrates with relatively weak benzylic carbon-hydrogen bonds. The high reactivity with phenols was unexpected because analogous peroxidases typically do not react as quickly. Additionally, according to the kinetic data, APO-II seems to be a milder oxidant compared to APO-I, which was expected based on other systems.This research provides insight into CYP-like reactivity by investigating a key intermediate in the hydroxylation reaction. According to Dr. Groves, “The surprisingly high reactivity of APO-II toward weak C-H bonds may facilitate the development of more selective biocatalysts.” Journal information: Proceedings of the National Academy of Sciences Explore furtherlast_img read more
