    The recall shows that Tesla programmed its vehicles to violate the law in
    most states, where police will ticket drivers for disregarding stop
    signs. The Governors Highway Safety Association, which represents state
    highway safety offices, said it is not aware of any states that allow

    Subject: Tesla recalling 54000 vehicles (The Guardian)

    Risks are many: Actually developing software that breaks the law. All-way
    stop signs, common on North American roads, require drivers to halt
    completely, before proceeding. Tesla's software drives the car over the
    stop line at 5mph. Misleading pseudo- technical marketing terms e.g., Full self-driving that isn't. Abusing well-known terms (e.g., that have long
    been used in aircraft as meaning just that). But in Tesla it is less sophisticated than full self-driving. Reliance on members of the public to
    do beta testing of sophisticated software with no knowledge of its design, functionality, failure modes etc. The delay in getting the feature removed. First discussed 20th Nov will be removed 28th March.

    Subject: Ancient Programming Language Is Way More Common Than We Thought

    Joel Khalili, *TechRadar*, 4 Feb 2022,
    via ACM TechNews, Wednesday, February 9, 2022

    A report by enterprise software provider Micro Focus found that more than
    800 billion lines of COBOL code are in daily use worldwide, about three
    times more than expected, despite a decline in the number of developers familiar with the 60-year-old programming language. Moreover, nearly half of developers surveyed predict an increase in the volume of COBOL used in their organization in the coming year, while a similar share said they expect
    COBOL applications to live on for at least another decade. The report found that 64% of companies reliant on COBOL prefer to modernize their apps rather than replace them, while 92% of respondents said COBOL will retain strategic importance to their business. Said Micro Focus' Ed Airey, "For IT leaders, supporting core business systems, COBOL application modernization lies at
    the heart of digital transformation."

    [COBOL could be here forever. Thus, Y2K+N problems are likely to recur
    for all nonnegative integer values of N. Might RISKS still be around in
    perpetuity? All the evidence from the past suggests it would still be
    relevant. The year 3000 would certainly deserve a major celebration.

    Thinking more in the short term, is there anyone who would like to
    consider taking on RISKS when I finally have to give up the ghost? 36.5
    years seem to have passed quickly since 1 Aug 1985, but RISKS is still a
    labor of love for me (with lots of help from you all), and the volume of
    would-be contributions never seems to diminish. PGN]

    also cellular service for providers who use CenturyLink's fiber as a

    France 24, 3 Feb 2022 via ACM TechNews, 4 Feb 2022

    Major oil terminals at some of Western Europe's biggest ports have been hit
    by a cyberattack, as energy prices in Europe soar amid tensions with gas supplier Russia. In Belgium, authorities are investigating the hacking of
    oil facilities in the country's maritime entryways, including Antwerp,
    Europe's second biggest port, while German prosecutors are investigating a cyberattack targeting oil facilities in what was described as a possible ransomware strike. German newspaper Handelsblatt said an initial report
    from German security services identifies the BlackCat ransomware as the tool used in the cyberattack in Germany. BlackCat emerged in mid-November 2021 as
    a software tool that allows hackers to seize control of target
    systems. Experts note that BlackCat is programmed in the Russian language.

    Subject: A crypto breakthrough? Western states consider taking digital
    currency (Politico)

    Proposals in Wyoming and Arizona to accept tax payments in Bitcoin and other cryptocurrencies would undermine the dollar's unique status..= .

    The dreams of crypto enthusiasts inched closer to reality in recent days as lawmakers in Wyoming and Arizona put forward proposals that would allow
    those states to accept tax payments in the form of digital currencies.

    The new proposals, and others like them around the United States, threaten
    to erode a key distinction upholding the supremacy of the U.S. dollar over
    its would-be digital competitors: Americans can use U.S. dollars, but not cryptocurrencies, to pay their taxes.

    Under the Arizona proposal, the state would recognize the most popular cryptocurrency, Bitcoin, as legal tender. The Wyoming proposal, which is not limited to any specific cryptocurrency, would apply only to sales and use taxes.

    Both proposals face potential legal and political hurdles. But Wyoming has
    gone further than any other state in passing laws to accommodate
    cryptocurrency adoption, and backers of the proposal there believe it will
    be the first state to take a significant step in the realm of tax payments. [...]

    Subject: An inside look at how one person can control a swarm of 130 robots
    (PopSci)

    Virtual reality and artificial intelligence helped with the daunting task

    Last November, at Fort Campbell, Tennessee, half a mile from the Kentucky border, a single human directed a swarm of 130 robots. The swarm, including uncrewed planes, quadcopters, and ground vehicles, scouted the mock
    buildings of the Cassidy Range Complex, creating and sharing information visible not just to the human operator but to other people on the same
    network. The exercise was part of DARPA's OFFensive Swarm-Enabled Tactics (OFFSET) program.

    If the experiment can be replicated outside the controlled settings of a
    test environment, it suggests that managing swarms in war could be as easy
    as point and click for operators in the field.

    ``The operator of our swarm really was interacting with things as a
    collective, not as individuals,'' says Shane Clark, of Raytheon BBN, who wa
    the company's main lead for OFFSET. ``We had done the work to establish the sort of baseline levels of autonomy to really support those many-to-one interactions in a natural way.''

    Piloting even one drone can be so taxing that it’s not rare to see videos of first-time flights leading immediately to crashes. Getting to the point
    where a single human can control more than a hundred drones takes some skill—and a lot of artificial intelligence.

    In total, the swarm operator directed 130 vehicles in the physical world, as well as 30 simulated drones operating in the virtual environment. These 30 virtual drones were integrated into the swarm's planning and appeared as indistinguishable from the others in the program to the human operator, and
    to the rest of the swarm. As apparitions of pure code, tracked by the swarm
    AI, these virtual drones flew in formation with the physical drones, and maneuvered around as though they really existed in physical space. [...]

    Patching operating systems and applications to remediate vulnerabilities is commonplace.

    Far fewer pay as much attention to maintaining the more firmware responsible for low-level system hardware maintenance.

    Recent generations of processors use implementations of the Extensible
    Firmware standard, referred to as EFI, to manage processor hardware at a low level. BleepingComputer reports that a widely-used implementation of EFI has
    a number of exploitable vulnerabilities that can compromise
    systems. According to the article, several of the vulnerabilities affect
    "power management and hardware control" including secure bootstrap.

    The article contains a list of the CVE entries describing the
    vulnerabilities.

    Subject: It's Not Just the IRS -- the US Government Wants Your Selfies
    (WiReD)

    A controversial new program that uses facial recognition is part of a
    national effort to verify identities and reduce fraud.

    In November, the Internal Revenue Service launched an online security system that uses face recognition to confirm a person's identity. Public attention
    to the project last week triggered an outcry. The ACLU called the project *deeply troubling*, saying face recognition ``has been shown to be less accurate for people of color.''

    Some IRS functions, like scheduling payments but not filing taxes, now
    require first-time users to verify their identity with Virginia startup
    ID.me, which also works with 27 state employment agencies and the Veterans Administration. The process involves photographing a government-issued ID
    and uploading a video selfie so algorithms can match face and document.
    [...]

    Goodman says that such programs need to provide offline options such as visiting a post office for people unable or unwilling to use phone apps or internet services. Making any digital service universally accessible in a
    large and varied nation like the US is a challenge. An agency like the IRS
    has to serve a user base similar in scale to that of a large tech company,
    but unlike a hot startup must also include society's least connected. Usable security is really, really hard, government's track record on digital
    inclusion is mixed. ID.me says it has 650 locations where people can
    complete enrollment in person in a big country. https://www.wired.com/story/irs-us-government-wants-selfies/

    This process was like playing Simon Says with an evil/demented robot. For starters, there's no initial list of steps to take and what will be
    required. So it was multiple iterations finding what was necessary. Then
    facial recognition didn't like initial images I uploaded. And it took
    several identical attempts to get improved images recognized, which it did, after a while. None of this gives me faith in its reliability/scalability.

    via ACM TechNews, Wednesday, February 9, 2022

    Researchers at the U.S. Department of Energy's Argonne National Laboratory
    and the University of Chicago (UChicago) have realized 100 million quantum operations, hailed as a key step toward achieving quantum supremacy. The
    team added single electrons to quantum bits (qubits) with laser
    pulses. "[The] emitted light reflects the absence or presence of the
    electron, and with almost 10,000 times more signal," said UChicago's Elena Glen. "By converting our fragile quantum state into stable electronic
    charges, we can measure our state much, much more easily. With this signal boost, we can get a reliable answer every time we check what state the qubit
    is in." The single-shot readout method deletes all previously loaded errors, enabling coherent quantum states to "perpetuate" themselves.

    Subject: About Elon Musk and tracking of his private jet
    You may have seen stories over the last few days about Elon Musk supposedly offering a teenager on Twitter $5K to stop sending out tracking info
    regarding his private jet (apparently not the only aircraft he tracks). Last
    I heard, the $5K was rejected, Musk hadn't responded to a counter offer of
    $50K or other possibilities.

    The thing about this is that it's a battle Musk is almost certain to
    lose. The data involved is ADS-B aircraft transmissions that are easily received with the proper (relatively inexpensive) equipment.

    The FAA recently established a voluntary program for the "masking" of actual plane ID data from ADS-B. The program involves substituting a "temporary" ID that doesn't map to any publicly available registration data, and could be changed no more frequently than once every 60 days (ultimately to be once
    every 20 days).

    The flaw in this plan is obvious. Once an aircraft has been identified
    through some other means (such as knowing when someone leaves a specific airport and noting where they are headed or land based on the kind of information typically available regarding many public figures), that "temporary" ID can then be used (until it is changed) for tracking pretty
    much just as easily as the unmasked ID. And there are Internet sites where enthusiasts openly trade this information.

    So even if Musk got this particular person to stop tweeting the location
    of his jet, it is extremely likely that another person (or persons) would
    take up where the original tweeter left off.

    The sudden hit Wordle, in which once a day players get six chances to guess
    a five-letter word, has been acquired by The New York Times Company.

    The purchase, announced by The Times on Monday, reflects the growing
    importance of games, like crosswords and Spelling Bee, in the company's
    quest to increase digital subscriptions to 10 million by 2025.

    Wordle was acquired from its creator, Josh Wardle, a software engineer in Brooklyn, for a price in the low seven figures, the company said the game
    would initially remain free to new and existing players.

    https://www.nytimes.com/2022/01/31/business/media/new-york-times-wordle.html

    Not sure that this represents a Risk to the Public, per se, unless one considers the tens of millions of lost productive person-hours spent on the game. But the HTML underlying the phenomenon is so trivial -- it really is just a single static page of HTML -- that it has already attracted malicious hackers (see, e.g., "A bot tried to ruin Wordle by posting the next day's answer. Twitter suspended the account". https://www.washingtonpost.com/technology/2022/01/25/twitter-suspends-wordle-ruining-bot/

    such as TWA Flight 514 did in 1974. (The more formal term is CFIT:
    Controlled Flight Into Terrain.)

    B) "Just fix/change the altimeters..."
    Not only is that not that not easy; a sharp filter may well need added
    space, add loss to the system, and change the inherent delay, but also
    these kind of changes would have to meet a FAA TSO spec, and that has not
    yet been written.

    Someone I chatted with who dealt with a parallel C-band co-channel issue on satellite downlinks saw/used a 7'-long waveguide filter, but that takes
    space and it added loss of 1.3 dB; neither desirable when in an aircraft seeking a reflected bounce of very low levels.

    I can hazard a guess if the cellco's want this to go away soon, once and for all, *they* could just swap out all the iffy domestic radar altimeters for
    new ones that would fulfill the obviously upcoming TSO. That is maybe
    cheaper & faster than years of lobbying and legislation. And if there is a crash even suspected of being 5G related...

    C) What about the phones?
    I know nil of the down and dirty details for 5G protocols, but what
    happens when an on-board, but not in airplane mode, phone hears a C-band
    tower signal and answers back? That's not the power level of a ground
    cellsite, but it's far far closer to the altimeter's receiver.

    D) IFR helicopters
    They use radar altimeters everywhere, not just on defined approach paths
    to large airports. A prime example are Medivac flights. Some are IFR rated
    but even the ones not may well have/use a RA.

    In conclusion I see:

    Two agencies, both gutted by indifferent/hostile Congresses, lacking their technical expertise of decades past, rushing to a political 'answer.'

    Intense political/economic pressure to make this issue Just Go Away NOW.

    But in aviation:
    Haste Makes Graves.

    In the Air France 447 and Boeing 737 Max crashes, the autonomous systems
    got confused by faulty sensor information and the pilots couldn't recover

    This is correct for the 737 Max crashes, but not for AF447. The sensor
    failure did not cause the "autonomous systems" to do anything except turn themselves off. The problem was rather with the design of the human-computer interface which gave confusing information to the pilots. If the pilots had done literally nothing when the autopilot disconnected, except applying the very basic airmanship of maintaining aircraft attitude, the accident would
    not have happened.

    Subject: Re: UK's Telecomm Providers Switching to Digital Phone Lines
    (Cornish, RISKS-32.04)

    Many households already have VOIP -- a lot of them are cable, and most new-builds no longer get POTS, so we have quite a lot of experience over
    here.

    Likewise, DECT is pretty much standard already. The problem is, all the
    phones you see in the shops are DECT-1 (analog line), and BT don't tell you your new phones are DECT-2 (VOIP). The switch is EASY PEASY so long as they don't leave you floundering for information!

    Oh - and to make it clear exactly what is happening, the national
    rollout is FTTC - "Fibre to the Cabinet" (for people who don't know what
    that means, there are street boxes serving maybe 100 houses, that's the cabinet. Unless you choose, and pay, it'll still be copper from there
    into your house. So the phone connection in your house won't change at
    all unless, like us, you are too close to the exchange to have a cabinet.)
    n
    BUT: As somebody who has already been told "we are switching you over"

    The consequences include:

    1. Householders having to re-arrange their domestic phone systems -- to
    establish a connection to their router. Or replace their handsets with a
    Digital Voice compatible one.

    That's pretty easy. Your old router plugged in to your phone socket. So
    unless they've wired your new cable router somewhere completely
    different from your phone line, you unplug your landline from the POTS
    socket, and plug it in to the router (or if you don't have broadband,
    the alternative box they provide).

    2. However, BT Digital Voice appears to only work with the routers (Smart
    Hub 2) they provide!

    This is (like with DECT-2) probably just lack of information - I don't
    know, I can't find any information!

    3. BT state that if consumers have a monitored alarm that's connected to
    their landline (like a health pendant or monitored burglar alarm) they'll
    need to speak to their alarm provider before moving to Digital Voice.
    Apparently these systems will stop working.

    4. Oh and if there's a power cut or your broadband fails, you'll be unable
    to make calls using Digital Voice, including calls to 999

    No 3 is a direct consequence of No 4. Burglars used to cut phone lines -
    which is why modern alarms mostly use mobile SIMs nowadays - so that's a new manifestation of an old problem. Health alarms will just have to move too.

    5. Some areas have no broadband services / or they fail often

    You forget - some areas NEED broadband as backup for a poor mobile service!

    (The whole point of this manoeuvre is to provide a modern, reliable
    broadband service. It won't fail (much) and will be available everywhere
    POTS currently is.)

    Risks: very limited news / announcements about the programme, issues over requiring householders to change their equipment / undertake technical re-configuration with limited / little support. Elderly / vulnerable residents a risk.

    6. Short dialling no longer works. You have to use the long STD code every time. More of a nuisance than anything else, but again it's the elderly/vulnerable that are hardest hit.

    We fall into the elderly/vulnerable category, and the biggest problem
    was the lack of information and unexpected side effects. I think it took
    us two or three months to realise what was going on, during which time
    people ringing us had a lot of difficulty making contact. And we didn't
    have a clue anything was wrong ...
