Default USB connection


Not strictly XP but...

I like to keep my USB-connected external drive disconnected in case of
ransomeware until I need it, every day for file backup. Problem is, the
connectors go bad after so many uses too quickly. Is there some sort of
switchable connector plug that I can use instead?

TIA

Metal-barreled USB connectors are rated at 5000 connections.

(*Don't* buy USB flash keys with plastic barrels, as
they're rubbish. Buy only ones with metal. While the
metal ones, the connector can snap at the joint to the
PCB of the USB key, rendering the key dead, that's
much better than the poor plastic barrel mis-aligning
and the interior pins snapping off on the first usage
of the thing. The plastic barrel bends too much.)

If a metal USB connector failure is to occur, you can accelerate
the process by applying force to the barrel, to split it
open at the metal seam. The metal Firewire connectors were
a bit worse for this problem. Some of my early USB 1.1
connectors have high friction, and probably won't
be making it to 5000 cycles (sandpaper effect).

Whereas your internal SATA hard drive connectors are rated
at 50 connections. And actually manage to do more than that.
ESATA (another external metal barrel type) have the
high rating like the USB. I can't even buy an ESATA cable
at my local computer store, to do any ESATA testing.

*******

There are 1:2 or 1:4 USB switching boxes, where if you
use just one USB port, you can "switch away" and "switch back"
to the single port you wish to connect and disconnect. On a few
of those products, it's the control switch on the top which
is made of inferior material and dies before its time. There
is at least one report of switch failure here. I don't
think I ever saw any "quality" implementations. All
sub-$20 rubbish. Nothing "MIL-spec" :-(

Just keep it connected and make sure it is not shareable on the web.
That way you want get any ransom demands!!

The alternative is to get desktop external HDs that can mounted using
network cable. Effectively, you create your own "cloud" to access your
files.

Are you the same KenK who has about 20TBs of useless data that needs to
be backed up everyday three times a day? This must be keeping you very
busy

In a recent warning, Cisco warns that the next wave of
Ransomware (not here yet), will use worm technology. So
be ready for just about anything. For criminal enterprise,
this is the "start of a new era" for them. The sky is
the limit. An exploit could end up coming in through
Adobe Flash, and end up spreading to all the
other running computers in the room via a worm.
It hasn't happened yet, but Cisco was very helpful
to the Black Hats, by mentioning it.

Even if you disable all your shares, but leave a USB
drive running on your other computer, a worm would
give them the access they need. To encrypt the
entire room. A USB switch is at least some minor
sort of protection. Not worth a lot, if the ransomware
bides its time (waits a couple days until the time is
right). There have been malwares in the past, that
waited 30 days before striking, so waiting is not
abnormal in terms of design. They could then
flash-encrypt all the NTFS $MFT in the room,
in the same 30 second interval.

I would class us right now, as pretty well defenseless...
All it takes now, is staging a redirect on Yahoo News,
using bogus advertising material, and they could
have 100 million victims in the blink of an eye.
And the incentive is financial, which is the best
incentive of all. I'm sure they're all quite busy
in the design phase right now, and don't have time
to read this post.

You might consider using a powered USB hub (one that works with your
drive), allowing you to unplugged/turn off the hub when you want to
break the connection.

I wasn't aware that was possible.

You can choose to not share it on the network. I decided that it wouldn't
help. Sure, well-behaved programs would be fine. The objective of
malware is to circumvent normal modes and infect you anyway.
My conclusion is that the only safe drive is one that's powered off...
and never powered on while connected to ANY PC that has EVER been
connected to the network. That's why we have to do stuff that's
not completely safe.
