    Google Bans Cryptocurrency Mining Apps From the Play Store
    By Catalin Cimpanu, July 26, 2018
    https://www.bleepingcomputer.com/ne...yptocurrency-mining-apps-from-the-play-store/

    "Google has updated the Play Store policy page this week to ban apps that mine cryptocurrencies on users' devices.

    "We don't allow apps that mine cryptocurrency on devices," the newly added policy entry reads.

    This change means Google will start to remove any app from the official Play Store that uses a device's CPU or GPU for cryptocurrency mining operations.

    Google will still allow mining apps on the Play Store, but only those that are used to control cryptocurrency mining operations on remote devices —such as servers or desktops.

    Untethered cryptocurrency mining can destroy devices
    Preventing cryptocurrency mining on Android is crucial because untethered mining operations can easily overheat or destroy batteries —or even devices if the battery case deforms, leaks, or catches fire.

    Such scenarios have already happened. Android malware strains like Loapi and HiddenMalware have been known to cause physical damage to infected smartphones.

    Google didn't publicly announce the policy change, but developers who had apps removed complained on Reddit. Other policy changes were also made, such as the decision to ban apps with repetitive content. You can read the new "Restricted Content" section of the Play Store Policy Center here, and compare it to an earlier version here.

    Apple banned mining apps last month
    The company's decision to ban cryptocurrency mining apps on the Play Store comes after Apple banned mining apps from the App Store at the start of June.

    Google previously banned Chrome extensions that mine cryptocurrencies from the official Chrome Web Store back in April.

    Google and Facebook have recently banned cryptocurrency-related ads from their ad platforms because they have been regularly abused to promote scams and phishing sites."

    Bitcoin, Ether Sink as ‘Sense of Panic’ Grips Crypto Investors
    By Eric Lam and Yuji Nakamura, August 13, 2018, 7:47 PM PDT
    https://www.bloomberg.com/news/arti...low-6-000-as-almost-everything-crypto-tumbles

    "Fear of missing out turns into broad digital coin sell-off
    Ether and other smaller tokens are falling faster than Bitcoin"

    "Bitcoin touched below $6,000 and dozens of smaller digital tokens including Ether retreated as this month’s sell-off in cryptocurrencies showed few signs of letting up.

    The largest digital currency fell as much as 6.2 percent to $5,887, the lowest level since June, before paring some of the drop, according to Bloomberg composite pricing. Ether sank as much as 13 percent, while all but one of the 100 biggest cryptocurrencies tracked by Coinmarketcap.com recorded declines over the past 24 hours.

    The total market capitalization of virtual currencies dropped to $193 billion. That’s down from a peak of about $835 billion in January.

    “Most cryptocurrencies have been overvalued for a very long time,” said Samson Mow, chief strategy officer at blockchain developer Blockstream Corp. “It’s hard to pin this move on any particular factor, but it feels like the opposite of last year when money piled in as people felt FOMO. Now it’s piling out as they sense panic.”

    While cryptocurrencies rallied in July on hopes that a Bitcoin-backed exchange-traded fund would attract new investors, U.S. regulators have yet to sign off on multiple proposals for such a product. The letdown has coincided with growing concern that entrepreneurs who raised crypto-denominated funds via initial coin offerings are now cashing out of holdings such as Ether, the token for the Ethereum blockchain that is a popular platform for crypto projects.

    “The big story in the market today is the huge weakness in Ethereum,” Timothy Tam, chief executive officer of CoinFi, a cryptocurrency data analysis company, said in a phone interview. “Bitcoin has held up relatively well versus Ethereum. It’s still quite weak versus the U.S. dollar.”

    At the height of Ether’s rally last year, the digital coin comprised 32 percent of cryptocurrency market capitalization, coming within striking distance of Bitcoin’s 39 percent. Ether now makes up about 14 percent, while Bitcoin accounts for 54 percent after falling less quickly than its smaller peers, according to Coinmarketcap.com.

    “ICOs that have raised a lot of money are really feeling a lot of pain” as their crypto holdings lose value, Tam said.

    Ether has tumbled about 40 percent this month, while Bitcoin has dropped about 26 percent.

    It’s unlikely that recent global market turbulence, fueled by Turkey’s currency crisis, is impacting cryptocurrencies, said James Quinn, head of markets at Kenetic, a blockchain company with investment and advisory businesses.

    “Correlations historically have been extremely low between cryptocurrencies and other asset classes,” he said in a phone interview from Hong Kong. “Which is one of the reasons why there is interest in this space and why people want to make an allocation in this space.”

    Still, anyone expecting Bitcoin to provide a haven from turbulence in global markets will have been disappointed. The cryptocurrency’s slide against the dollar this month is almost as big as the Turkish lira’s 25 percent slump.

    Putting Stickers On Your Laptop Is Probably a Bad Security Idea
    From border crossings to hacking conferences, that Bitcoin or political sticker may be worth leaving on a case at home.
    by Joseph Cox | Aug 14 2018, 5:27pm
    https://motherboard.vice.com/en_us/article/pawvnk/stickers-on-laptop-operational-security-bad-idea

    "Plenty of hackers, journalists, and technologists love to cover their laptop in all manner of stickers. Maybe one shows off their employer, another flaunts that local cryptoparty they attended, or others may display the laptop owner’s interest in Bitcoin.

    That’s all well and good, but a laptop lid full of stickers also arguably provides something of a red flag to authorities or hackers who may want to access sensitive information stored on that computer, or otherwise cause the owner hassle.

    “Conferences, border crossing, airports, public places—stickers will/can get you targeted for opposition research, industrial espionage, legal or investigative scrutiny,” Matt Mitchell, director of digital safety and privacy for technology and activism group Tactical Tech, told Motherboard in an online chat.

    Mitchell said political stickers, for instance, can land you in secondary search or result in being detained while crossing a border. In one case, Mitchell said a hacker friend ended up missing a flight over stickers.

    Plenty of people take disposable devices with limited information or account access on them to events like the annual hacking conference DEF CON. That way, if the device is stolen or otherwise compromised, the attacker should only be able to obtain information you’re more prepared to expose. But it’s still probably not a great idea to draw a target on yourself with an identifying sticker.

    Mitchell said he saw a person on a plane likely flying to DEF CON with a sticker of a particular media organization. “This person had a Chromebook, I guess as a travel laptop,” Mitchell said. “But it had a media sticker on it.” Mitchell also sent Motherboard a photo of the laptop.

    Naturally, a journalist’s computer, which may contain information on sources, could be an attractive target, not necessarily for some sophisticated attacker, but just someone who fancies trolling and making that reporter’s life more difficult.

    Of course, this all depends on your own particular threat model, and the motivation of the attacker. As Moritz Bartl, who heads a group that runs parts of the Tor anonymity network, pointed out on Twitter, when burglars broke into his van, the only thing they did not steal was the stickered laptop.

    “Police assumed it was [left behind] because it is hard to resell,” Bartl wrote. So, petty thieves looking to fence a laptop may be somewhat dissuaded from picking up a computer covered in stickers.

    But in certain contexts, it may be worth not parading a bunch of stickers around.

    “Buy an outer case and sticker that **** up,” Mitchell told Motherboard. “Keep it at home when you travel or swap with a clean outer case.”

    Mitchell sent Motherboard a photo of his current laptop post-DEF CON—clean, and with no visible affiliations.

    “It's ok to be yourself and have fun,” Mitchell said. “Support your favorite nonprofits, open source projects, and surveillance circumvention tech. But nothing comes at no cost or risk.”"
