Okay, I've noticed an unknown computer showing up in my Finder on my and my girlfriend's Macbooks.

I've determined that I can hide it by deselecting bonjour computers from finder's advanced preferences. I have used "Get Info" on the computer and determined that its a "PC server" according to that. I have double and triple checked the MAC address of every single device on my router, only my devices are showing up under the DHCP Table on my WRT54G2 router (two Macbooks, one iPod Touch, and one Xbox 360). I have always had a secure network, and recently even redid the security to make sure (WPA2 security, non-broadcasted SSID). I am running completely up to date Snow Leopard on my Macbook and my girlfriend is running up to date Leopard on hers.

Here's a screenshot of my default Finder window showing the mystery computer:

Here is a screenshot of the "Get Info" dialogue window from the mystery computer:

What in the world is this computer, and aside from just hiding "Bonjour computers" from Finder, how can I kick this thing out of here?

Someone on your network, Is it a shared connection?

Well I my network has always been secured. And I've recently changed my wireless security settings: I turned off broadcast of my SSID, I made a much more complicated passkey, and I enabled MAC Address Filtering (I've always had WPA 2 Personal turned on).

If I connect my Macbook directly to the router via cables & disable Airport on my Mac, I won't see that mystery computer. I'm fairly certain that its not someone on my network, as I drastically changed my security settings and I never see this mystery computer on my router's DHCP Table. Here's a screenshot of that right now, the three computers listed are my Macbook, my girlfriend's Macbook, and my iPod Touch:

I've noticed that on my Mac. If I don't setup the workgroup it would pick up any surrounding PC's. Maybe try that and see how it goes?

I'll freely admit I am a newb at Macs (only been a full time Mac user for a year), but I thought Workgroups were a PC only thing and I don't have any PC computers on my secure network. If that is the case, how do I change the Workgroup on my Mac?

Well not sure where you got "pc server" info from? From that mac address its a apple branded device

That's actually really cool that you can look that up. I got that "PC Server" thing from using "Get Info" off the right click context menu on that device from Finder (I screenie'd it in my first post).

As an update, though, I called Apple and they stated that it was probably a Windows 7 PC located on the same subnet from my ISP. They stated it was Windows 7 because they said it simply has a stronger online presence and it was nothing to worry about.

Sounds like he knows alot!!

yeah a windows 7 PC with mac of apple interface? Does that sound right to you?

Stronger online presence? Um your behind a NAT router - so why would you being seeing machines that are connected to the same ISP as you? None of that makes any sense. If that was the case -- why are you not see MORE of them? If your seeing machines connected to your ISP, you would be seeing a lot more than 1 ;)

I get this sometimes. I've noticed that my iMac turns into a "PC" icon when the machine itself is on and connected to the network (its connected printers and hard drives are available over the network), but it's in a sleep/low power mode. But once I actually power it back up, the icon changes back to the familiar iMac icon.

Oh I agree, it sounds absolutely retarded. It honestly sounded like he couldn't care less about my issue despite my giving him as much information as possible.

Well thanks for all the help guys, but I seem to have figured this out myself. My girlfriend had Printer Sharing enabled on her computer (which was supposed to be on) and for whatever reason that also creates that "mac0017f22b93a7" computer to show up as well... since +BudMan pointed out that the address was from Apple Computer, Inc. I assume that its just something her Mac is creating.

Which makes me wonder why the guy I called from Apple was so far off on this one... :huh: anyways, thanks for all the input guys, much appreciated.

Hihi! Nice CRT! :cool:

Also, I found that icon quite humorous as well.

Yeah those so called "geniuses" at the genius bar -- yeah not so much ;)

I don't even own a mac, and get a fair share of side jobs from people that the geniuses couldn't help.. hehehe

Maybe an Intel Mac running Windows 7? The easy way to figure out what computer (or device) is causing it would be to find out the MAC addresses of all of the devices on your network and see which one matches the name that is showing up. Also, remember that your ethernet and Airport connections will have different MAC addresses, so look at both of them on each of your computers.

      Well, it seems version 4.9 doesn't work well at least when trying to make a WinToGo USB. It ends very fast with an error. Had to use 4.8 instead.
    • Hundreds of printer models with weak password algorithms exposed, no firmware patch possible

      By Usama Jawad96 · Posted

      Hundreds of printer models with weak password algorithms exposed, no firmware patch possible by Usama Jawad Many people don't think or care about it, but printer security is a pretty important avenue when it comes to evaluating your cybersecurity posture. Last month, it was found that the companion software for Procolored printers was distributing malware. Now, it has been revealed that hundreds of printer models all over the globe are susceptible to attacks targeting their admin credentials. Bleeping Computer has reported that CVE-2024-51978 is a one of the eight printer vulnerabilities recently discovered by security researchers. Combined, these allow authenticated and unauthenticated attackers to discover the default admin password, perform remote code execution (RCE), crash the printer, and leak other sensitive information. Severity ratings go from a score of 5.3 (medium) to 9.8 (critical), indicating that these are pretty severe vulnerabilities. The most dangerous vulnerability in there exposes the default admin password, and primarily affects Brother printers. This is because Brother utilizes a rather weak password generation algorithm that is highly dependent upon the device's serial number and a static salt table. Analysis of the code revealed that the first 16 characters of the serial number are appended with eight bytes from a static salt table, with the results being hashed with SHA256 and Base64-encoded. Finally, the first eight characters are then taken and some of them are replaced with special characters to form the password. The static nature of the password generation algorithm means that an attacker can chain various existing vulnerabilities to get access to your serial number and eventually your default admin password. It is important to note that not all printer models are affected by all of these flaws, but the default admin password exposure does affect 695 models. The breakdown for the number of printer model affected by the eight vulnerabilities is as follows: Brother: 689 Fujifilm: 46 Konica Minolta: 6 Ricoh: 5 Toshiba: 2 Brother has informed the security researchers that it cannot fully remediate the password generation vulnerability through a firmware patch. It can only fix the issue in its next printer models by patching the problem during the manufacturing process. This makes it crucial for customers of affected models to change their default admin password as soon as possible, which is good practice anyway.
