Phew, that's a relief. Guess that's a reasonable compromise for a $550 product for which there are no other quality competitors.

My friend/colleague had her phone stolen while she was napping in the hospital room of her terminally ill husband. Fortunately it had MDM. Called Palo Alto PD, I sat with them and tracked it from the hotel and it was already in San Jos

Um, Windows 11 still hasn’t moved all the necessary utilities and administrative panels over to the windowing toolkit Microsoft introduced in 2012, and MacOS 26(??) is… hideous.

Thomas is one of the pickier, crankier, least faddish technologists I've ever met. If he has gone fanboy that holds a lot of weight with me.

Depending on what he actually did to enumerate that database and whether he downloaded all that PII I think changes the risk profile.

IANAL and this is not legal advice, but you probably fine reverse engineering a mobile app and intercepting your own network traffic. He was doing ok until he started enumerating IDs in their database, at which point he started venturing in

Agreed. I've been doing this for 25+ years and personally know a dozen people who have been threatened and several who have been sued or faced potential prosecution for legitimate security research. I've experienced both situation

They aren't talking about general purposed datacenters, but satellite uplink stations. These new constellations of low-Earth orbit (LEO) internet satellites (like Starlink) can network with each other but eventually need to downlink in

A regression means that PhotoDNA scanning was working, and then stopped working correctly. This happened in the last several months, well after Mr. Musk's takeover. I think it is good that they fixed it. That is why we directly reached

We use Microsoft's PhotoDNA scanning service on all images we intake for research, which has access to hash banks collected by NCMEC, a government-sponsored clearinghouse on child exploitation, and the Tech Coalition, the private group

This is an incorrect reading of our report. Twitter has scanned for CSAM using PhotoDNA for years, and is an early member of the Tech Coalition of companies working on this issue. What we discovered is that, since Musk's takeover, that

Hi, I'm one of the authors of the report. You have pretty significantly misread it. > You might as well say, "Private unmonitored housing and properties implicitly allow the trading of CSAM." The issue with Telegram is tha

Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.

To nitpick the nitpick, Stanford actually is held to some Constitutional standards, thanks to California's Leonard Law, which requires private universities to provide the same free speech protections as public universities. It does not

The advertising ASN does not share any upstream peers. So it might not be a hijack, but it is an interesting event and could be related to the conflict. Untangling ISPs that have operated in both countries or with subsidiaries is going to g

What would you know about production networking, Jeremy? I'm in the same boat. If the dozens of IT pros who are complaining about this can't get AT&T to swap out a single router card, what hope do most folks have?

It's called scalable video coding. The source sends multiple streams of packets depending on their upstream, and the more streams you get the higher quality the resulting video. Each client can tell the server which streams they want t

In both the "normal" case and in situations where end-to-end encryption is enabled, the audio and visual streams are individually encrypted with AES-GCM-256 using a key derived from a shared per-meeting key. The difference is that
