They were 100% taking pictures of naked high schoolers. It's just that someone was manually deleting them. One of the notes on the trial was that there *should* have been far more material based on the logs, but it had been deleted.

From the Wiki article, the computer consultants that recovered images weren't able to get everything, so someone knew how to at least do something dban-ish to individual files and folders. I'm not sure if it's possible to recover data that's been zeroed out or random-overwritten - never got that deep into IRL computer forensics.

I just assumed that the "consultants" weren't third-party. I wonder if the "unrecoverable" images were just from a single chunk of time being gone or if they were sprinkled throughout, indicating a very selective deletion. Also I wonder if the software could somehow circumvent the green light next to the cameras. edit: aha, apparently TheftTrack "got around" the camera light by just taking quick snapshots. Geez.

A ticket came in.... for myself. My own Win10 work laptop is in a weird situation where I'm running out of space on the SSD... no problem, I'll delete some folders. Except that any folder I try to delete, Windows just ignores the command. For any files: I can use the delete key, or I can right-click and delete, or I can drag to the trash, or I can use WinDirStat to directly erase files, and all of those work fine. For any folders however, whether the folders contain files or are completely empty, all of the above methods I just mentioned fail, with no feedback or error message. Any method I use to delete, it just acts like nothing happened after I take the action. I've never seen anything like this before. Logging in as admin or rebooting the laptop makes no difference. I know it's a Monday and all but is my brain broken or is something fucky going on? edit: and it says I have full permissions, obviously edit 2: trying to use command line RMDIR as both myself and admin account returns "Access denied." with no elaboration, again the permissions are full control for both of said users.

Even then, there's a method of reading the disk surface that gets you the state of the disk as it was before it was overwritten even +7 times because we're talking about magnetic state which doesn't fit into neatly-defined perpendicular or shingled tracks - although it should be said that this isn't something that most threat models have to consider, because very few bad actors have access to the necessary technology as disk heads nowadays float a few hundred nanometers above the surface of the disk.

Okay, ran into a weird one today. Big boss on site couldn't export to PDF from MS Project 2016. Figured something weird on his PC, have him email me the file. I can't export it either. No crash or anything, but the file never gets created. If I save as the "older" Project 2007 format, then I can export, but that messes some of the data in the file up. Can't seem to find much on Google (going to take a run in the AM when my brain isn't already melted), but has anyone seen this before/have any ideas?

Seems to be something having to do with OneDrive; deleting a folder in the O365 web portal will cause OneDrive to delete the folder on my end. The few folders I have that aren't synced to OneDrive can be deleted normally. At least now I can get rid of the huge iCloud backup I took for a user.

Ebdrup posted:There's no such thing as DBAN'ing individual files or folders as you cannot securely delete files or folders in a filesystem structure, you have to work with a character device that represents the actual hardware rather than a block device, since blocking or filesystem caches can lead the firmware to queue these commands such that they have no real effect, and on any LBA48 disk can take longer than it does to physically shred it. I’m curious to learn more about this. What is a “character device”? So really the only way to securely erase a single file is to delete it, create a file with the same name, save it and delete it, and do this six more times?

While not perfect, SDelete (Sysinternals) seems to be the closest for FAT/NTFS. There appears to be caveats when dealing with files that have special attributes and with NTFS MFS, but short of nuking the entire drive this is probably the best you're going to get. https://docs.microsoft.com/en-us/sysinternals/downloads/sdelete

Agrikk posted:I’m curious to learn more about this. In FreeBSD, Poul-Henning Kamp decided to get rid of them around 2000 after a long discussion starting back in 1999 which involved the Kirk McKusick of the Fast/Unix File System (which directly inspired ext in Linux, and probably many other filesystems both directly and indirectly, and is still being worked on by him), as well as David Greenman (who was among the two people who originally made FreeBSDs unified VM subsystem in the early 90s and has managed to scale to todays workloads), as well as many other people. Primary reasons for removing block devices was that UFS by that time could do its own file-level caching (managed and tracked by the unified VM), and the fact that in some rare cases with removable media it could lead to disk corruption or a lack of reporting errors (which later on meant that GEOM, a modular disk framework that allows you to do arbitrary level stacking of encryption, mirroring, RAID, compression, and soon checksumming, could be implemented and know about errors from further down-stack - and incidentally, GEOM was made by phk too). To answer your other question in less than long-form: You can't secure delete the files on any filesystem that uses journaling, copy-on-write, log-structures, or can do snapshotting (either or multiple of those properties describes basically every filesystem used in production). You can wipe disks to the point where only state-level actors are a threat, but I would hope that someone in charge of protecting data against state-level actors wouldn't have ask about it on this gay dead forum.  The solution is to use FDE - although even with software implementations you risk running into trouble because for example BitLocker communicates(/communicated?) with the TPM in plaintext so you can easily get the encryption key despite a key conforming to OPAL spec (which defines hardware implementation FDE). The one advantage that FDE has is that as long as the data is cold (ie. the system isn't suspended or live), there's not a whole lot presumably anyone can do. (*): Except all the stuff that isn't.

Block devices always have _some_ kind of caching in the virtual memory system of any Unix-like implementation. This is an awesome explanation that opened about a half dozen new tabs on my browser.

Having worked with atomic force microscopy, which is the core of how they read the disk for recovery, I don’t envy the poor bastards who do it. Couple hundred thousand for the instrument, god knows how much for the probe needles that are the part that reads the disk (they break since they’re nanometers thick), and weeks of testing time. Then you’d have to figure out what the hell you actually got. A couple universities come to mind that do it, past that it’s governments or very specialized companies. Cool as hell though. Luckily my experience was with semiconductors that didn’t need as much work. The lesson here is if you really wanna be sure you wiped a disk forever, toss it in a furnace and slag it.

Thanks for that. I did a bunch more playing, and its even weirder. Project just straight up will not export to PDF. Created a brand new project file, same issue. Try opening multiple existing ones that have been PDF'd before, nothing. Multiple PC's, etc. All kinds of weirdness. However, I did manage to get "Print to PDF" working...so, at least something works. Now to figure out why Skype for Business refuses to work with any microphones...onboard or USB attached.

A ticket came in: Can you make sure the teaching stations in these rooms are good to go for the training tomorrow? Smartpanel, PC, document camera, classroom audio, and make sure the Chromebooks and iPads are charging. I just set them up last week, and they were all working fine, but I guess I'll go double-check. Man, what's up with this tech teacher's computer? The HDMI got moved from the GPU to the onboard, so it's not sending anything to the Smartpanel. The teacher cops to plugging it in the wrong place, but...why was it disconnected in the first place? It's so slow, it's like it's thrashing the SSD, but disk usage isn't very high, and neither is CPU or memory usage. It seems like it's running major updates, but only wsappx seems to be doing much of anything. Performance tab says...what the gently caress? 0.23ghz? Look into the side window on the case (the people who bought the cases got them windows and LEDs for teachers' computers for some weird reason), and I see the loving CPU HSF laying on the GPU. The people who installed these were not very good, unless a stock Intel HSF can get knocked out by the case falling over. And this is like the third time I've seen it over the past 4 years. Snap, push, and twist, and it's back to running at 3.2ghz. Next two days, I'm looking forward to cleaning 168 Chromebooks with a microfiber cloth and some spray cleaner.  Then moving them to classrooms and getting charging stations for ~340 Chromebooks and ~170 ipads wired and tidied.

I can't be arsed to go back and dig up the old post, but a few years ago I was involved in some drama involving the wicked Property Control Clerk, a staggeringly poorly documented equipment disposal, and the most lies I've ever seen a human being tell. I almost lost my job and got into serious legal trouble over the property clerk throwing mountains of buses on top of me to protect her own rear end. Since then, I've made sure to never communicate with her unless it is through email or text. There is no such thing as too much CYA with this woman. I've dotted my Is and crossed my Ts. I've waited. And today, the wicked Property Control Clerk was finally slain. She was not slain by a massive theft. She was not slain by the Department of Education catching her shredding legal documents. She was not slain by a carefully laid trap from yours truly. She was slain by a $120 pocket projector that was purchased three years ago, found wanting, and left forgotten in a desk. The director suddenly remembered its existence yesterday and set out to find it, but it did not turn up. He tried to blame me, but I am blameless. He tried to blame the previous owner, but he is blameless. So he blamed the only one truly at fault: The Property Control Clerk. It was a small screw-up. It wasn't labelled as it was under the inventory price threshold. It was left in a drawer and accidentally discarded when they replaced the furniture in that office last year (as best as I can figure). What happened, and what the director is infamous for, is that suddenly inventory was on his radar. He went over to her office and demanded to see every scrap of paperwork she has on all of our inventory, suddenly discovering that there is no paperwork. There has been no paperwork for years. Just hastily scribbled notes on various notepads and post-its. He came to ask me what my experience with her was, to which I responded that it has been resoundingly negative and that I fear for my job every time inventory is involved as there are documented cases of her altering paperwork and destroying documents to protect herself. I reminded him of the botched disposal that almost cost us half a million in penalties. She did not last the day. I feel pity and relief.
