I have no comment on the politics of this stabbing attack, and only note that the attacker used a ceramic knife — that will go through metal detectors.
I have used a ceramic knife in the kitchen. It’s sharp.
EDITED TO ADD (6/22): It looks like the knife had nothing to do with the attack discussed in the article.

Turns out, multi-million dollar yachts are no more secure than anything else out there:
The ease with which ocean-going oligarchs or other billionaires can be hijacked on the high seas was revealed at a superyacht conference held in a private members club in central London this week.
Murray, a cybercrime expert at BlackBerry, was demonstrating how criminal gangs could exploit lax data security on superyachts to steal their owners’ financial information, private photos and even force the yacht off course.
I’m sure it was a surprise to the yacht owners.

I’ve previously written about the serious vulnerabilities in the SS7 phone routing system. Basically, the system doesn’t authenticate messages. Now, criminals are using it to hack smartphone-based two-factor authentication systems:
In short, the issue with SS7 is that the network believes whatever you tell it. SS7 is especially used for data-roaming: when a phone user goes outside their own provider’s coverage, messages still need to get routed to them. But anyone with SS7 access, which can be purchased for around 1000 Euros according to The Süddeutsche Zeitung, can send a routing request, and the network may not authenticate where the message is coming from.
That allows the attacker to direct a target’s text messages to another device, and, in the case of the bank accounts, steal any codes needed to login or greenlight money transfers (after the hackers obtained victim passwords).

Fitbit evidence is cited in an arrest warrant, stating that the device monitored steps by the victim after the suspect claimed she died.

This is an interesting combination of computer and physical attack:
Researchers from the Russian security firm Kaspersky on Monday detailed a new ATM-emptying attack, one that mixes digital savvy with a very precise form of physical penetration. Kaspersky’s team has even reverse engineered and demonstrated the attack, using only a portable power drill and a $15 homemade gadget that injects malicious commands to trigger the machine’s cash dispenser. And though they won’t name the ATM manufacturer or the banks affected, they warn that thieves have already used the drill attack across Russia and Europe, and that the technique could still leave ATMs around the world vulnerable to having their cash safes disemboweled in a matter of minutes.
“We wanted to know: To what extent can you control the internals of the ATM with one drilled hole and one connected wire? It turns out we can do anything with it,” says Kaspersky researcher Igor Soumenkov, who presented the research at the company’s annual Kaspersky Analyst Summit. “The dispenser will obey and dispense money, and it can all be done with a very simple microcomputer.”

Turkish hackers are threatening to erase millions of iCloud user accounts unless Apple pays a ransom.
This is a weird story, and I’m skeptical of some of the details. Presumably Apple has decided that it’s smarter to spend the money on secure backups and other security measures than to pay the ransom. But we’ll see how this unfolds.

Matthew Green and students speculate on what truly well-designed ransomware system could look like:
Most modern ransomware employs a cryptocurrency like Bitcoin to enable the payments that make the ransom possible. This is perhaps not the strongest argument for systems like Bitcoin — and yet it seems unlikely that Bitcoin is going away anytime soon. If we can’t solve the problem of Bitcoin, maybe it’s possible to use Bitcoin to make “more reliable” ransomware.
Recall that in the final step of the ransom process, the ransomware operator must deliver a decryption key to the victim. This step is the most fraught for operators, since it requires them to manage keys and respond to queries on the Internet. Wouldn’t it be better for operators if they could eliminate this step altogether?
At least in theory it might be possible to develop a DAO that’s funded entirely by ransomware payments — and in turn mindlessly contracts real human beings to develop better ransomware, deploy it against human targets, and…rinse repeat. It’s unlikely that such a system would be stable in the long run humans are clever and good at destroying dumb things but it might get a good run.
One of the reasons society hasn’t destroyed itself is that people with intelligence and skills tend to not be criminals for a living. If it ever became a viable career path, we’re doomed.

This is what passes for news these days.
As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

It’s not hard to imagine the criminal possibilities of automation, autonomy, and artificial intelligence. But the imaginings are becoming mainstream — and the future isn’t too far off.
Along similar lines, computers are able to predict court verdicts. My guess is that the real use here isn’t to predict actual court verdicts, but for well-paid defense teams to test various defensive tactics.

While we’re on the subject of terrible 9th Circuit Court rulings:
The U.S. Court of Appeals for the 9th Circuit has handed down a very important decision on the Computer Fraud and Abuse Act…. Its reasoning appears to be very broad. If I’m reading it correctly, it says that if you tell people not to visit your website, and they do it anyway knowing you disapprove, they’re committing a federal crime of accessing your computer without authorization.
