Re:Fuck You Microsoft.
You are assuming:
1. That people feel that they're in a position to do something about it, which they often aren't ("just use Linux" isn't practical for some, especially those who are technically inept). Plus they feel helpless in their digital lives in general, since Google and Facebook and everyone else does it. Google and Facebook and everyone else do it doesn't mean it's right, contrary to people such as yourself who think that's a good excuse.
2. That people are aware of it in the first place. Most people are rather appalled when someone bothers to tell them what "telemetry" means in actual terms, let alone when people start pointing out things such as the ToS for Office 365 where they can tell you what you can and can't make with their software. And before you say "but that's only for Office 365!", well, they're trying to force Windows 10 into being a service, so it's only a matter of time.
Tell Mr. Gates to hire a better shill, he's not getting his money's worth with you.

Re:My Synology NAS has antivirus, why not a SmartT
It does protect against Linux malware too. It's a Linux box running an older kernel with numerous services exposed, and periodically exploits are found.
For example, this flaw in Samba was pretty severe: https://nakedsecurity.sophos.c...
Still not convinced that McAfee is the best solution, but a Linux based NAS is not immune to malware either.

Real threat or industrial espionage?
Security cameras and their hub systems have been hacked like crazy, largely because the average user (homeowner, retail lackey, office lackey) doesn't even bother changing the default passwords, much less a firewall or any reasonable security measures. Here's a report of a website streaming over 70,000 hacked cameras, and here's a report of over a hundred police surveillance cameras being hacked to send spam right in DC. They're plenty hackable, just a matter of whether the Chinese state thinks it's worth risking sanctions from the countries they're surveilling.
But this could also easily be industrial espionage. In the US, anyone competing with Huawei could simply spend a few million lobbying to convince congress that it's happening. No proof is required, only that the capability is there, and that if China was doing it we might never know.

It's somewhat sad that then people didn't ...Wow, careful there Linus. Forgot all about the Copy On Write bug that you fixed in the Linux kernel in 2005, but which you then unfixed, declared "theoretical" and which was then ignored for over a decade until it hit the fan in 2016?
This is an ancient bug that was actually attempted to be fixed once (badly) by me eleven years ago [] but that was then undone due to problems on s390 [W]hat used a purely theoretical race back then has become easier to trigger.

Re:It's so easy to do it right
So what?
Not sure if you're trolling, unaware or making some sort of pedantic argument. Key stretching and adaptive hashing are considered best practice and here's a couple references to read up on including some from TFA. These solutions will partially mitigate the impact of weak passwords.

From another source:
In theory, Apple’s Face ID authentication is supposed to require eye movement to work. But Marc Rogers, researcher and head of information security at Cloudflare, told Forbes that he’s recently discovered that photos of open eyes work just fine.

Re:The weakest security
Are passwords that hard to remember?
Once you start requiring them to be 12 characters long, and contain at least one uppercase character, one lowercase character, one numeral, and one Egyptian hieroglyph they are.
By the way, those complexity rules have been officially withdrawn by NIST. In fact, TFA is an instance of the very problem that drove the rule change. Now all we have to do is spend 20 years undoing the damage of the old, stupid, complexity rules.

I don't believe I've seen anyone react to that bomb threat with anything other than disapproval.
In denial much? Open any article on the subject and browse the comments. For example, from here:
- Sounds like someone called in an anonymous bomb threat. Cute.
- Got me all excited there for a second, bummer.
- Not the most productive thing for sure. But what's the alternative?
- Considering Pai's complete disregard of the public's opinion on the matter, or the many accusations of fraud on the comment period, I think at this point it's a moment of "desperate times call for desperate measures."
I'd say, the ratio of approval to disapproval there is 1:1...

Re: Embrace and Extend
Bingo.
I'm very glad the Windows has a good way to run Linux programs. Why? Well, I don't want to waste an afternoon figuring out which three lines I need to write to handle something that any reasonable desktop OS would handle with no hassle.
By which time you've probably spent several weeks insecurely downloading Chromium to have a proper web browser, going through YouTube videos learning how to restore your desktop functionality, making sure to turn off the windows store so your kids don't auto-install some malware searching sites to try to find instructions to turn off the spyware features, probably managing to get some other drive by malware in the process. Installing antivirus software, then removing it when you find out that it had malware included.
But, cutting and pasting a three line script. That's really the time killer. Isn't it.

Re:wrong direction
the "one plug for everything" trend that began with USB Type C is a step in the wrong direction.
Yes. It's bad for security. Suppose a friend asks you to copy a file onto a USB stick. Temporarily forget about exploits in filesystem code when reading corrupt filesystems. Since USB can work as either storage or a keyboard, your friend might have caught a USB stick controller firmware virus that emulates a keyboard and types things that exploit you.
Now suppose a port can connect either storage or a video card. Video cards use PCIe. Instead of a keyboard, the malicious stick now has hardware debugger access to physical RAM and can establish persistence on your machine without exploiting the OS, like Thunderstrike 2:
What to do? Avoid plugging untrusted Thunderbolt devices into your Mac, for example if someone you don’t know offers to lend you a network adaptor at a conference.
It's difficult to make use of this kind of speed, like 1/10th of RAM bandwidth, through a hardware interface with small attack surface because it requires offloading intelligence from the CPU which means giving discretion to the hardware. The right way to create a security boundary while preserving speed is with a network interface, ex. Infiniband's "verbs," that explicitly post buffers that will be written into. USB's history is more generic. If they're just jacking the speed without transforming it into basically a network interface, then either it won't deliver the speed for applications other than storage, or it will leave users exposed to Thunderstrike 3. I hope it's the former but am pretty sure it's the latter.
It will be like BadUSB times nine thousand.

Re: They forgot to mention two important contribut
Smartphones and their apps track and trace peoples purchases, movements, social groups, etc. Apple itself is but a small portion of it but they created a surveillance ecosystem.
Google (Hint: the maker of Android) reads your mail, tracks your browser history, your shopping habits and your movements among other things. I'm pretty sure Apple is an amateur convention compared to Google when it comes to monitoring every single thing their customers do.
Actually, Apple has, and continues to, take great steps to NOT track you.
Even when they want anonymized statistical data, they have instituted cutting-edge techniques to separate the data from the user's, or device's, IDs. Here's some examples:

Re:vaccine
Via Sophos:
In cases where the SMB exploit fails, Petya tries to spread using PsExec under local user accounts. (PsExec is a command-line tool that allows users to run processes on remote systems.) It also runs a modified mimikatz LSAdump tool that finds all available user credentials in memory.
It attempts to run the Windows Management Instrumentation Command-line (WMIC) to deploy and execute the payload on each known host with relevant credentials. (WMIC is a scripting interface that simplifies the use of Windows Management Instrumentation (WMI) and systems managed through it.)
So on networked systems, if a host has the "vaccination" gets hit but has credentials for other systems that permit logon/execution saved, then it can still spread. If you don't save networked credentials for other PCs on your network on a given PC, then it shouldn't be an issue on a fully patched network.
I could see this being an issue on corporate networks if Windows Server is not fully patched and a server like AD has a network logon that is valid across a wide number of client PCs/other servers, but the impact on most home networks is likely minimal.
Still wouldn't hurt to apply the 'vaccination' to each PC you own as a precaution though. -

Re:Honeypot ransomware
Sophos supposedly has technology (intercept X) that can heuristically determine when an encryption event is going down and should automatically block it. It works by looking for files being rapidly encrypted and immediately stops it and i believe tries to roll back the changes so that less than 1% is actually encrypted.
For us, the virus scanner has caught a few ransomware viruses before they made it that far, so we have yet to test that. But its a well advertised feature of their product line.

It requires its own license, and I think its selling like hotcakes these days.

Re:I feel left out
You mean like Heartbleed or Shellshock? Or how about the one that not only affected Linux PCs but also affected every Android device from 4.4 on up thus leaving tens of millions vulnerable on devices that will never be patched? Or how about when the Linux Mint site was serving malware? Like that?
Joke all you want about MSFT but at least their OS gets 10 years of patches, you don't see tens of millions of Windows machines at risk because MSFT won't provide patches. Oh and just FYI since the Linux community was so quick to claim "Android is Linux!" you might want to know that by that metric Linux infections are skyrocketing while windows infections are dropping like a stone making Linux the most malware ridden OS on mobile networks which it has been for 3 years running now...congrats!

Re:What should happen and what will happen
The second to last Yahoo security breach was so bad in part because the passwords were hashed with a completely unsalted MD5 https://nakedsecurity.sophos.com/2016/12/15/yahoo-breach-ive-closed-my-account-because-it-uses-md5-to-hash-my-password/. The lack of salting would have been by itself a problem even when MD5 was still considered secure.
Actually, even with salting, no standard cryptographic hash function is appropriate for password databases. You can squeak by if you iterate the hash function enough times, but even that is pretty weak, since it means that an attacker with lots of GPUs -- or, even worse, special-purpose hardware -- can perform hashes so much faster than you can that the key stretching you obtain is minimal.
The state of the art in password hashing is algorithms like Argon2, with parameters that are tuned to require significant amounts of not just CPU time, but RAM and threads. Argon2, tuned to require, say, 10ms of time on four cores and 256 MiB of RAM, is going to significantly strengthen passwords. The RAM requirement means a GPU with 4 GiB of RAM can only test 16 passwords in parallel, making GPU-based cracking essentially useless, since what GPUs provide is huge parallelism. Custom ASICs would do better, but would still run into bottlenecks on the speed of the RAM. Making really fast cracking hardware would require either huge amounts of RAM, or large amounts of extremely fast RAM. Either way, big $$$.
Even better, if at all possible you should use a hash that is keyed as well as salted. Doing that requires having some place to store the key that won't be compromised by the same sorts of attacks that compromise your password database. In most cases that's hard to do. Argon2 will accept a key so you can get both sorts of protection, though if you can be really, really certain that no attacker can ever get the key, then you can use a standard cryptographic hash function in a keyed mode, e.g. HMAC-SHA256, though I'd still recommend using a purpose-designed password hash (e.g. Argon2) in case your key is compromised.

What should happen and what will happen
If one looks at the history of what happened the last time a major hash was broken, there was a large gap between when MD5 has its first collisions and when it became practical to detect collisions. There was about a little under a decade between when the first collisions were found and when it became easy to find collisions. The general expectation is that hash systems will fail gracefully in a similar way so we have a large amount of warning to switch over. Unfortunately, we've also seen that in practice people don't adopt new hash algorithms nearly as fast as they should. The second to last Yahoo security breach was so bad in part because the passwords were hashed with a completely unsalted MD5 https://nakedsecurity.sophos.com/2016/12/15/yahoo-breach-ive-closed-my-account-because-it-uses-md5-to-hash-my-password/. The lack of salting would have been by itself a problem even when MD5 was still considered insecure. That in 2015, a decade after MD5 was broken for almost all purposes, Yahoo was still using it, is appalling. Unfortunately, they likely aren't the only one. And I fully expect that if Slashdot is around in a decade we'll read about someone who has foolishly stored passwords using SHA-1.

The problem with "proper" security is that it works against the user
NIST guidelines:
Favor the user. To begin with, make your password policies user friendly and put the burden on the verifier when possible.Long passwords that you can't remember
NIST guidelines:Applications must allow all printable ASCII characters, including spaces, and should accept all UNICODE characters.. We often advise people to use passphrases, so they should be allowed to use all common punctuation characters and any language to improve usability and increase variety... No composition rules. What this means is, no more rules that force you to use particular characters or combinations
so far no one has come up with a better way to do it.
