Ran across this on on sed, under,
"OT: Weird search engine problem - fake goods hijacking"
but thought you might see it here.
Not my post but I find it interesting, thought you may also.
Mikek
 
I have encountered a weird search engine problem with Google, Bing and
Yahoo all affected to some extent. Some search result URLs have been
corrupted and hijacked to fake designer goods stores and I can't see how
it has been done. I have tried from different platforms and it seems
that the problem is with the indexing and content at the search engine.
 
To see what I mean with a concrete example take a look at the top two
hits for the following search terms on Google:
 
Hermes fake cromorecastle
 
On my system this forces two mangled websites to the top of the list.
Their genuine URLs are below however Google doesn't link to them any
more nor does it show the true content of their web pages. Any wizards
able to explain what is going on and how to get things put right?
 
http://www.cromorecastles.co.uk/
and
http://www.shockcordstore.co.uk/
 
It looks like a contagion with an increasing number of sites gaining
spurious fake designer brand title additions even if the URL for the
moment remains unmolested. I first saw the problem on Bing this morning
but careful investigation shows that it is much more widespread.
 
The unqualified bare URL is typically the one that is hijacked but I
have seen spurious titles appear in deep links too.
 
I don't think it is my router or ISP's DNS gone haywire. I have ruled
out PC malware as I see exactly the same problem from Android via
another route.
 
I have now got independent confirmation that the searches done through
an entirely separate route give the same results.
 
 
Thanks for any enlightenment.

Funny, I get none of the above. Just legitimate hits for how to spot fakes and other links containing those words. Exactly what I would expect.

Sorry. I was rather busy yesterday and missed the fun. It looks
normal with no garbage mixed in. I also don't have time to do much
digging on the topic today. So, I'll guess(tm) a little.

Offhand, I would guess(tm) that someone hijacked the DNS record for
thse sites and changed them to point to the Chinese site or sites.
Google search just followed the change to the new site. The nslookup
results look normal today. For example:
 
C:\>nslookup
Default Server: RT-N66U-63B8
Address: 192.168.1.1
> set type=any
> cromorecastles.co.uk
Server: RT-N66U-63B8
Address: 192.168.1.1
 
Non-authoritative answer:
cromorecastles.co.uk MX preference = 20, mail exchanger = mx1.123
cromorecastles.co.uk MX preference = 10, mail exchanger = mx0.123
cromorecastles.co.uk
primary name server = ns.hosteurope.com
responsible mail addr = hostmaster.cromorecastles.co.uk
serial = 2009042402
refresh = 86400 (1 day)
retry = 3600 (1 hour)
expire = 1209600 (14 days)
default TTL = 14400 (4 hours)
cromorecastles.co.uk internet address = 94.136.40.103
cromorecastles.co.uk nameserver = ns.hosteurope.com
cromorecastles.co.uk nameserver = ns2.hosteurope.com
cromorecastles.co.uk nameserver = ns.hosteurope.com
cromorecastles.co.uk nameserver = ns2.hosteurope.com
 
- It looks odd as the 4 hr TTL (time to live) which
- suggests that hosteurope.com is trying to flush the bogus
-
- Oops, something is wrong. When I point my nslookup to the
- authoritative name server, I get a lookup failure:
 
> server ns.hosteurope.com
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.

> server ns2.hosteurope.com
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
*** Can't find address for server ns2.hosteurope.com: Timed out
 
- They're using what seems to be a locally hosted backup
- DNS server. It should be somewhere offsite. Checking...
- OK, I'm wrong. The IP addresses pring returns for ns and
- ns2 are quite different, and therefore probably at different
- locations.
Pinging ns.hosteurope.com [212.67.202.2] with 32 bytes of data
Pinging ns2.hosteurope.com [62.138.132.22] with 32 bytes of data
- I have no idea if the IP addresses are the correct ones.
 
So, the servers are there, but they both don't respond to DNS
requests. Well, not quite. They respond to lookup request for
Google, CNN, my domain, and other sites, but not to
cromorecastles.co.uk. Argh, I lied again. Looks like it's back to
normal:
 
> server ns.hosteurope.com

Server: ns.hosteurope.com
Address: 212.67.202.2
cromorecastles.co.uk nameserver = ns.hosteurope.com

mx0.123-reg.co.uk internet address = 94.136.40.151
mx0.123-reg.co.uk internet address = 94.136.40.153
mx0.123-reg.co.uk internet address = 94.136.40.154
mx0.123-reg.co.uk internet address = 94.136.40.61
mx1.123-reg.co.uk internet address = 94.136.40.150
mx1.123-reg.co.uk internet address = 94.136.40.152
mx1.123-reg.co.uk internet address = 94.136.40.151
mx1.123-reg.co.uk internet address = 94.136.40.153
mx1.123-reg.co.uk internet address = 94.136.40.154
mx1.123-reg.co.uk internet address = 94.136.40.61
 
So, my 3rd guess(tm) is that hosteurope.com is trying to fix some kind
of problem. Time for me to run away.

Perhaps I was just asking him to confirm or otherwise expand on his statement against using selenium in this application, or (more likely) was that I was tweaking the old guys in this forum who remember exactly what odoriferous emanations a selenium rectifier provides as evidence of it's failure..

Watched to local news last night, anyone following their instructions
will *reset* his router to the defaults.

Yep. That's because the average reporter or announcer doesn't know
the difference between reboot, reset, restart, power cycle, cold boot,
hot boot, etc. Little surprise because the older computahs had a
button labeled "reset" that did a "reboot". However, when the button
moved to modems and routers, it did both a reset (wipe all settings),
and a reboot (restart the OS). I partly solved the problem by
covering the hole with a round label inscribed with "$35" which is
what it will cost them to have me drive over to their office and put
Humpty Dumpty back together again.
 
Of course, nothing happens without a suitable conspiracy theory. In
this case, I must ask why the FBI insisted that everyone reset their
routers when only a few models are susceptible. Also, ISP's like
AT&T, can easily reboot their customers routers using SNMP. My
initial guess was that the FBI thought it better to be sure than sorry
when dealing with credential sniffing malware. However, the FBI has
never been known for such lofty sentiments. My guess(tm) is that this
may well be the first technical action in recent memory that the FBI
has performed mostly correctly. They may need the good publicity it
brings to compensate for the general impression of gross incompetence
demonstrated by the Apple iPhone unlocking fiasco.
 
Unfortunately, my prediction of personal economic enrichment may have
been premature. National Reboot Your Router Day has produced only two
paying service calls and a few unprofitable phone calls and emails.
Very disappointing. Still, I predict additional press releases in the
future by the FBI to remind us that we're being successfully protected
from the machinations of the Russians.

No need to hack your own route. Just use the "route" command to
direct your packets to whever you want:

Most automated attacks arrive from hijacked client computers or
botnets. For DDoS attacks, it looks like attacks originating in the
USA are the major culprits, with China in 2nd place:

You don't charge enough. It costs 3-4 times that to have a plumber call.

More likely the FBI is helping the NSA install their own sniffers
into every router that gets rebooted, and not just the vulnerable
ones. Of course, that theory presumes competence, so it's probably
wrong.

Also: "Cisco said part of the code used by VPNFilter can still persist
until the affected device is reset to its factory-default settings."
 
So a reset actually might be required.

They insisted ? Fukum, I didn't do it. Hold on, there's a knock at the door...
 
...
 
...
 
Don't worry, I shot them. Now, is this possibly the cause of my having trouble to get to certain sites ? These are mainly sites I have never been to before. Everything I normally use is alright, but anything new seems to time out and that is in more than one browser.
 
Maybe some DNSes got screwed up or something like that, but the places I frequent have a backup somewhere ? <just a wild guess

Thanks to media attention, the FBI has provided me with a busy day or
two. According to the press release, we're expected to reboot every
router to flush out the malware the evil Russians have installed:
<https://www.google.com/search?q=FBI+reboot+your+router>
The list of affected routers is rather small:
<https://krebsonsecurity.com/2018/05/fbi-kindly-reboot-your-router-now-please/>
Easy enough. What could possibly go wrong?
 
Well, some experts, news agencies, and pundits have mixed up "reboot"
with "reset" your router[1]. Instructions are provided for inserting
paper clips and sharp instruments into any available hole in the back
of the router. Few seem to offer assistance in identifying which box
is the router. Doing a reboot will preserve the router settings.
Doing a reset will wipe them clean and precipitate a support call (to
me). So far, I only have 2 router reconfigurations on my schedule for
today, but I'm sure there will be more.
 
Therefore, I would like to thank everyone involved for generating the
work, and special thanks to Comcast and AT&T for disabling customer
firmware updates and save settings in their gateways and routers.
 
Update: I just received a phone call asking which box is the router.
This is going to be an interesting day.
 
 
[1] The probable culprit is the various Comcast VoIP gateways that
have an optional built in backup battery. In order to reboot these,
it is necessary to unplug the power from the gateway, remove the
battery for about 15 seconds, plug the battery back in, plug the power
back in, and watch the lights come sloooooowly back on.

Indeed, it's not like these are convoluted electronic devices. Intake
(mix of gas and air), compression, ignition, exhaust. Each cycle can be
tested easily enough - starting with a compression test.

This was in the mid '70s. I would have to have had an 8mm camera
with me at the time.

Just a random thought.
 
I used to work as a mechanic at a small engine repair shop.
One of the cartoons that found a home on the front counter:
 
A kid sitting in the driveway with the lawn mower totally
disassembled. And his dad standing there looking at him.
"I found the problem. It's out of gas."

Oh phooey. There is no way you can get a dangerous shock from slowly
turning over an old lawnmower engine equipped with a magneto. Sheeesh!

Exactly, on a small magneto like this it'll tickle, but this reminds me of a true story:
 
Many many years ago, a guy I knew was having some ignition work done on his stock Hemi Challenger at my buddy's garage, and brought along a magneto to try just in case. Just rotating it a half turn sent him flying! Those things have balls.

Was the mag the type that winds up when being turned over slowly? I
have some old magnetos that work this way. One is on my 1945 Gibson
tractor. When turned slowly it winds up a spring inside that lets go
when it reaches a certain tension, thereby spinning the magnet fast
enough to get a good spark. Those mags will deliver a really good
shock. Years ago I had one of these that would only deliver a little
tingle. Talking to a guy who knew about mags said that the coil may
have absorbed moisture over time, especially since the mag was from a
marine engine. He suggested baking the mag in oven at 200 degrees for
several hours and then letting it cool in the oven. I tried his
suggestion but was dubious. After it was cool I grabbed the spark plug
wire and turned the mag over. When it let go I got a really good
shock. Made my arm ache.

Magnetos were used as torture devices by the Nazis and other
unscrupulous folks and guess where they were hooked up...

No, just the type they used in race engines. Something like this:

They must have some pretty strong magnets and the voltage at operating
RPM must be VERY high. I guess that's what is needed for really high
compression engines.

At one time, I had a '55 Chevy 2-door sedan.
With a 437 cu in big block,Hilborn fuel injection
<https://kinsler.com/Shop/wp-content/uploads/2016/11/BBC-X-ram.jpg?9a05f9&9a05f9>
and other assorted"make a shit ton of horsepower" goodies.
 
One of them was a Hunt Magneto.
 
One day, while hanging out at a local wrecking yard, a guy bet me he
could kill my engine by pissing on it.
 
Heh. "$100 says ya can't."
 
I opened the hood, by tilting the whole front end forward.
 
He unzips his fly and I watch the golden stream arch over until it
hits the distributor.
 
My Chevy is still idling, and he's laying on his back screaming "My
dick!"
 
I just walked over to him, "When you're done screaming,you owe me
$100."

> Sound cut off, replaced with low frequency hum (thus amplifier is still active), Limiter led (red on bar graph) stuck ON, Turning it off and after a few minutes back on solves the problem.
 
> That problem was traced down to an 7915 voltage stabilizer on the main preamp/psu board, having an output of -8V instead of -15 on normal operation and after 15 minutes that voltage fell to 0 volts. Replacing the 7915 with another fixes the problem (solid -15V on output). My Stagepas 300 has an 7915 with plastic casing (too large heat resistanse to heatsink, I guess, and a semiconductor fatigue resulted to that problem). It looks that using a metallic 7915 is possible as the heatsink is electrically isolated from the rest of the circuit on my revision, if in doubt use some mica - plastic ring isolator there.
 
> Cheers.
 
Mak,
Did you replace the 7915 chip yourself or did you have it done in a shop. I don't trust myself to make this repair but the cutting out problem has made the Yamaha unit totally unreliable so I really need to try it. Any tips would be greatly appreciated.
Thanks J

I admire your avoidance of landfill! If all else fails, go electric, they have come a long way since the flip-over B&Ds back in the day. But! Look for corrosion around any connections, and look for a bad spark-plug wire, carbon tracks or similar. Otherwise, these coils have a limited life in that application.

There were a lot of Briggs and Stratton electronic type magnetos that
were prone to failure. I use a method to test suspect magnetos before
I spend much time trying to find out why there is no spark. Remove the
spark plug from the engine so that it turns over easily. Then stuff a
rod or something similar into the the spark plug boot so that it makes
good contact with the end of the spark plug wire. Now turn the engine
over slowly while holding the rod. You should get at least a tingle.
If no tingle then try turning the engine over a little faster. If
there is a little tingle then the problem is most likely a bad
connection. This could be a corroded ground wire. If, even turning
the engine over fairly fast, there isn't even a tingle the magneto is
bad or the kill wire is grounded. I have used this method for years
and it is a really fast way to find out if the mag is probably good or
not.

shouldn't be hard to continuity test the coil LT & HT sides. You have a multimeter?
 
Beware, connecting & disconnecting the meter on the LT side can cause a spark on the HT side.

Just finished working on this old beast. The display was flashing,
indicating an open amplitude control loop. The output vernier had no
effect. There is an op-amp error amp and it is socketed (741) so that was
easy to try first. No joy. Looking at the schematic it seemed the peak
detector diodes would be easy to check. Turns out that they are under two
covers but still not too hard. One cover is glued down but was easy to pry
off. One diode was open. I tacked in a 1N914/1N4148 substitute and
amplitude control was regained and no more flashing display. The output at
250 MHz is within 1 dB. Not too bad.
 
To fix it right, I am looking at a MMBD452LT1G.
Look165 <look165@numericable.fr>: May 24 07:53PM +0200

A 1N4148 will never be able to work at 250MHz.
