Twitter claims Elon Musk bailed from sale with 'invalid and wrongful' reasons

Kanhef

Depends on who the delays hurt more. If Twitter can use in-house lawyers, it doesn't really add to their costs no matter how long it goes on for. Either the company gets $1B in cash, or their stock gets bought out at (currently) 50% above market value; seems like a win for them no matter what. Musk has a lot more to lose if they decide to make the process painful.

If he has to dump Tesla stock to make the deal go through, it will drive the price down; who wants to be holding when that happens? The lower the price of Tesla stock, the more he has to sell, which could lead to a rapid crash as investors try to get out before he has to sell.

Next shareholder meeting should be interesting

The Twitter Board was very quick to agree to the sale, without considering if Muskrat was approaching it in good faith or not. With the shareholders not only losing out on a nice payout, but also seeing this fiasco tank the value of their shares, they could be motivated to replace most of the current board members.

Next time you open an app it will ask for permissions again, same as the first time it was installed. Even if it revokes permissions for an app you're using, it's not hard to grant them again. I don't see the problem.

Re: I guess I will have to wait then

Rather than banning the use of automated systems, simply make a law that companies are liable for any bias in those systems, whether or not it was intended. Companies will either stop using it, or their lawyers will insist that vendors prove that their system isn't biased before using it. Win-win.

The AN0M fake secure chat app may have been too clever for its own good

Kanhef

Re: Or maybe ...

I was thinking it's been a clever psych ops mission. AN0M was distributed through a chain of trust, and according to other articles they initially pitched it to one kingpin (who interestingly enough, has not been arrested), and let him spread it to everyone else. After this, someone may well create a truly secure communication platform, but anyone who's been paying attention to the news will be paranoid that it's actually another backdoored system made by the cops. Even someone pushing to use an existing service like Signal would be viewed suspiciously; how can you prove that service is actually secure?

Not just Excel

LibreOffice also likes to auto-detect data types, and then auto-format based on what it thinks you're doing.

One solution would be to have a setting for default cell formatting. Auto-detect can still be the default option, but let people set it so negative numbers are always red and in parentheses, for example.

Doing it wrong

The fake invoices tend to get noticed sooner or later. Instead, direct real purchasing and contracts to a company you control, which resells products and subcontracts the work. All at a healthy markup for profit, of course. Sure, the company could have spent less elsewhere, but it's hard to make that into a case for fraud.

If you could forget the $125 from Equifax and just take the free credit monitoring, that would be great – FTC

Boffin

Reading the settlement, clause IX.D says that if funds remain in the Consumer Fund (i.e., for credit monitoring) at the end of the claims period, it shall be used to lift the Alternative Reimbursement Compensation Cap (the 'up to $125' part). So if no one wants the credit monitoring, there's potentially up to $425 million available as cash – enough to give the full amount to 3.4 million people. Slightly better, though I'd still rather have them have to set aside $18 billion to fully compensate everyone affected.

Fake 'U's! Phishing creeps use homebrew fonts as message ciphers to evade filters

Kanhef

That was my initial thought as well. For a general-purpose email filter, it would have to check quite a few languages in order to not block every email written in, say, Italian or Thai. Also needs to be context-aware, so they can't avoid triggering the filter by just putting half of Moby Dick in an HTML comment.

Might be simpler to have a check for embedded fonts. If found, render the message into an image, apply OCR, and run filters again on the result.

Re: Self-driving cars don't need to be perfect to be deployed

An immediate slowdown or emergency stop at any uncertainty is extremely reckless and will kill people. Not could, will. It sounds like a great idea for a car on an empty road or test track, but think about the consequences if you're being tailgated, or are in dense 70 mph freeway traffic, or have a passenger who isn't wearing a seatbelt.

Remember that the majority of collisions with Google's self-driving cars occurred when they followed the rules of the road as written, but the person behind them wanted to run a yellow/red light.

WINE is also a volunteer project, made by people in their spare time. They also had to reverse-engineer the entire Windows API, including its many, many quirks. Considering that, they've done pretty well.

Rather than re-implementing the same, 30+ year old, crufted together API, I'd rather see them design a new, modern OS with a WinAPI virtualization layer. Somewhat like what Apple did with OS X and the Classic environment.

Re: Shove It Out The Door

In addition to an interest in computers, I spend a lot of time dealing with structural steel fabrication. It's astonishing how different the attitudes in these two worlds are. Computer programmers tend to take the approach of "it compiles - ship it". Security, efficiency, quality in general seem to be an afterthought at best. Structural engineering is governed by various industry codes, which make frequent use of the word 'shall', and often have the force of law. If a structure fails, and the designer or fabricator did not follow the relevant code(s), they can be held liable for that failure. I wonder if something similar is needed to tame the Wild West of programming: an RFC or ISO standard that establishes requirements for the design and testing of quality software. I wouldn't want it to be too restrictive, to allow development of new languages and methods of development, but at least set a minimum standard for proper engineering of software, extent of testing, what sorts of bugs identified during testing must be fixed before shipping.

It's probably impossible to prevent all bugs and security flaws, but we ought to be able to do something about this chronic parade of embarrassingly bad mistakes from companies that have the resources to do better.

How evil JavaScript helps attackers tag possible victims – and gives away their intent

Kanhef

Re: Obfuscated JavaScript and browser useragent redirects

Virus writers have been doing similar things for years. Over a decade ago, I found an infected website that used similarly obfuscated code to extract the browser and JS engine version numbers and sent them as part of a GET request to another domain, which presumably delivered the actual virus. Visiting that domain without providing a vulnerable version returned an empty document. Not too surprising that they'd be looking for other, more subtle ways to identify browsers.

Google Chrome: HTTPS or bust. Insecure HTTP D-Day is tomorrow, folks

Kanhef

Re: Not about encryption

Because they're worse than useless: they make a site look secure, but don't actually make it any more secure than an HTTP-only site. Anyone can write a self-signed cert for any domain, so MITM attacks are easy: the attacker just makes their own self-signed cert, and it looks just as valid as the original.

Re: Money talks...

What happens if and when someone is able to hijack the DNS record? By changing the public key, they can redirect traffic to a site they control which will be 'verified' as the real thing. Putting both address and authentication information in the same record creates a single point of failure.

Y'know... Publishing tech specs may be fair use, says appeals court

Kanhef

How far should it go?

Many specifications reference other standards. For example, say you want to build a data center. Most jurisdictions will require that you follow the International Building Code (IBC) for the structure, and I'm not even touching fireproofing, electrical, HVAC, etc. here. For the steel frame of the building, IBC says it shall be constructed in accordance with AISC 360. That will in turn require you to follow AWS D1.1, which invokes other standards for several things. Then you have steel decking, rebar, concrete, soil preparation, and so on. Even if the standards incorporated into law themselves are made available, they directly and indirectly require the use of dozens of other standards. Should all of those be made freely available as well?

How to pwn phones with shady replacement parts

Most shops don't have the ability to fabricate or program components like this; I'd worry about problems starting much higher in the supply chain. I can see a (probably Chinese) component manufacturer being paid to include ad-injection code. Not terribly different in principle from the bloatware cruft that PCs come preloaded with so often, but much harder to get rid of.

Overcharge customers, underpay the serfs. Who else but Uber (allegedly)

Kanhef

As far as user experience, this wasn't a bad idea. It's fairly common in some industries (e.g., restaurants) to provide worst-case estimates of wait times, so that when customers are provided service sooner than estimated, they are pleasantly surprised. So it's not unreasonable to give the passenger one estimated arrival time, while giving the driver a route that will get there slightly earlier, barring unexpected traffic delays.

What will get them in trouble is if they have been calculating charges and payments separately, as the lawsuit alleges. Without highly-improbable macroscale quantum effects, both routes cannot be taken at the same time, so either passengers are being charged for more time and distance than they actually spent in the car, or drivers are being paid for less time than they actually spent driving. Whichever one it is, that's a pretty strong case for fraud.

Bluetooth-enabled safe lock popped after attackers win PINs

Re: Bluetooth lock reasons...

It's the same reason many companies have switched to electronic door locks. When properly implemented, each person has a unique access code. Hard to duplicate, usage can be tracked, access can be revoked without affecting anyone else. Of course, when it's not properly implemented – as in this case – it ends up weakening security.

Re: Just a thought

I've been struggling to come up with a reasonable situation in which one would do this.

If you're sending video from one webcame to multiple recipients, you're probably using a single program to do it.

Using multiple programs for multiple video sources could make sense (for example, videoconferencing on a webcam while sending security camera footage to archive storage), but that situation is unaffected by this change.

I suppose you might want to split a video source if you want to stream live footage over the internet and record it at the same time, but only if you're using brain-damaged programs that can't do both.

FFS, Twitter. It's not that hard

Kanhef

Conversation-based ads

Ads based on a celebrity event, or sports game, or TV show are reasonable. Nobody really likes ads, but they can understand why they're there and no one will raise a fuss about it.

Then someone like David Bowie dies, and everyone talking about it sees ads for Bowie-themed merchandise, and it looks like a crass attempt to cash in on someone's death.

Then you get an incident like what's currently going down in Orlando, Florida, and everyone sees ads for guns. People get upset, looks like Twitter is happy to profit from a tragedy, lots of drama and PR damage control.

So maybe this isn't the best idea.

RIP ROP: Intel's cunning plot to kill stack-hopping exploits at CPU level

Kanhef

The problem with having a software-defined return address stack is that there's nothing to keep malicious code from manipulating it; as far as the processor is concerned, it's just another region of the process' memory. A hardware-defined shadow stack can more effectively restrict access: the processor itself is the only thing that should manipulate this area of memory (as a side effect of call and return instructions), so any attempt to alter it directly can trigger an exception.

I'm not intimately familiar with x86 instructions (I'd rather be dealing with Power or ARM), but it looks like this could be defeated if there's a way to write arbitrary data to the EIP register. Overwrite EIP, call the next instruction, and you've put your desired return address on the shadow stack.

Re: Making a hash of things

If someone steals the database, they don't need to reverse the hashes. They'll just throw a dictionary file at your hashing algorithm and look for matches. Doesn't take too long to brute-force every password up to 6 or 8 characters long as well. This is why you should be salting the passwords before hashing them, and forcing users to have sufficiently long passwords.

The biggest problem I see with the OpenSSL code is that it leaves you at the mercy of your compiler/optimizer. You have to trust that the optimizer will properly traverse all possible code paths and not strip out the entire if (0) block as unused/unreachable code. It may work fine for whichever compiler and optimization settings the developers used, but there's no guarantee it will work for everyone else.

Socat slams backdoor, sparks thrilling whodunit

Re: Interesting point.

Definitely not obvious - at least it didn't end in a 5 - but at the same time, any decent factorizing program would have reached 271 fairly quickly, so it's clear they didn't double-check the number in the code for primeness. Since one of the factors is so small, my guess is there was a typo of some sort; if I wanted to backdoor an encryption routine, I'd use a semiprime whose only two factors are roughly equal in length (~150 digits in this case), so it would take some significant number crunching to discover that it's not prime.
