back to article Google denies Redmond report of a spamming Android botnet

Google is disputing claims from a Microsoft researcher that a functioning botnet is operating on Android phones and spamming out Viagra and penny stock adverts to unsuspecting punters. Terry Zink, program manager for Microsoft Forefront online security, took time during the annual July 4 "We're kicking out the Brits and will …

So.....

Microsoft is upset that it's mobile operating system isn't performing as well as it would like and has decided to slur Android? Seriously - Microsoft "security" is only technical enough to examine the headers of spam to find it's origin? Like spammers actually advertise the email system they use....... "HEY WORLD, I'M SPAM THAT WAS SENT FROM AN ANDROID PHONE - COME AND NEUTRALISE ME NOW YOU KNOW WHAT DEVICE I LIVE ON"

*sigh* sometimes I wonder just what qualifications people need these days to be "technically qualified"

To be fair the "Sent from Yahoo! mail on Android" line is automatically added by the phone, so the spammers wouldn't be in control of that.

I think it's too early to say either way. Yes Microsoft is jumping the gun a bit, but Google are also being too full of themselves by not even admitting the possibility.

I once sent an E-mail to our CIO from Bill.Gates@Microsoft.com just to show how easy it is to spoof an address and to explain how SMTP headers allowed one to trace upstream. This was right after the first semi-complex address spoofing massmailer viruses came out in the early 2000s. He wanted us to somehow stop infected systems on the internet from spoofing our users' addresses.

Well you can avoid a lot of the spoofing by using SPF and locking up your mail server really well. Maybe it wasn't as widely available when you were at the company.

As for the matter at hand I find it very suspicious that a spammer would go to all the trouble of precisely cloning the structure of a Yahoo Android email, down to the messages IDs. It doesn't make a lot of sense.

The guy who found this may be on to something.

SPF is relatively new. Didn't exist 10 years ago.

The fact that every email has the same message id means its most likely someone who packet sniffed a android mobile sending a email from the app, and is duplicating the transmission with spam for the body.

Easy way to send email via Yahoo.

Message ids are unique for every email that is sent legitimately hence why its fairly obvious.

The spam uses a *fixed* message ID...

And anyone is seriously paying attention to this guy's claim that the message ID is real?

Good grief -- no wonder he's a manager, rather than someone who has a professional clue about email security. The folks over at SANS are undoubtedly laughing their collective arses off over the half-witted discussion about this.

Sure, Android -- and WP7, for that matter -- botnets are undoubtedly feasible. But it isn't going to be this PHB who uncovers one.

Re: The spam uses a *fixed* message ID...

What makes you think that the message ID is always one and the same? The wording of an ElReg article? Since when do you get reliable information from there? Go read the original articles.

At this point it is impossible to tell who is right. It is certainly possible that the messages are sent from a mobile botnet - but there is not enough evidence to prove it. It is also possible that the messages are sent from PCs and are faked to look as if sent from mobile devices. Finally (and my bet is on that) it is possible that vulnerabilities exist in some mobile app for accessing Yahoo! Mail and the spammers have used this vulnerability to create a bunch of accounts and are sending the spam from there.

Well - i won't be surprised. Office 365 (that Forefront is part of) support didn't know you can have 2 MX servers with same priority for domain ("It creates a bottleneck!").

Sadly, there seems to be some sort of misinformation about SPF doing the rounds.

I've seen a lot of spam over the last few weeks sent from forged addresses. Looking up the SPF records for the domains in question, they all end in "+all". :-(

"Sent from Yahoo! Mail on Android"

Er, I can add "Sent from " to any email I want as well. Or 'Sent From my iPhone' etc. Spoofing the message ID is a little harder, but still easier than writing a malware infected mail client and getting it onto a bot-net worth of hand-held's.

I would presume spammers are smart enough to know that having little things like that mobile client ID might be enough to reduce some algorithm's probability of marking the item as spam. My guess is that Baysian filters would learn that 99.9% of say Hotmail email is spam, where as little to no spam comes from mobile email clients in which the customer in theory pays.

My (evil) thought would be that all a spammer has to do, would be to offer cheap/free low end Android phones in, loaded with an app or infected version of Android. Would a student in a Nigeria turn down a free Android phone setup for pre-pay? All the device needs to do is be programmed to look at a bot-net controller for client adverts to be sent out, then whenever the device is on Wifi, sends the emails out at a moderate(ish) rate. Potentially then spam could originate from hundreds or thousands of Wifi points.. along with the Wifi password if the user has entered it....

Profitable spam mail depends upon a couple of people out of many thousands responding. The cost of each phone would mean each phone would have to send millions of spam emails to get enough responses just to cover the cost of the phone.

Google also once disputed that there was nothing wrong with their sales model. And then all of a sudden developers started to surface up to a point where Google locked /and/ removed said threads.

It would be bizzare...

... if in amongst all the free apps in the Android Market, at least one of the ones that requires full network access for unobvious and unspecified reasons, WASN'T some sort of trojan.

Regardless of the specifics of this particular report (the only correct position to take for now is wait-and-see), it's just dumb to think that there are not a ton of compromised android handsets belonging to the kind of person who doesn't carefully think about the permissions requested by each and every closed-source market 'Play' app they've installed. i.e. average persons.

Google's defensiveness is stupid, and is gonna come back and bite them, even if they ARE right in this particular instance.

Re: It would be bizzare...

I have to agree with that. And since there are Android tablets around which cannot use the Google store. Google cannot guarantee anything about Android apps.

Yes, you can "root" the tablet, but can you be sure of the security consequences? Is using Google Play for any Android apps any guarantee anyway? I don't know, but I wouldn't say that out-of-the-box Google Play access was a useless filter for choosing your Tablet. The Kindle app and the iPlayer app are worth having, and I have not seen them anywhere else.

I am sceptical about the malware claim, but the occasional false alarm does set people thinking.

The logic of my initial post is pretty basic - all you have to do is ponder whether it would be a sensible thing to try for someone invested in distributing malware, given that there are people invested in such.

Infact, that first reply is glaring in being possibly itself exactly what it accuses me of being. Hmmm?

No one has mentioned whether or not we are taliking about a standalone virus or is it is malware hidden within a program( sorry App).

Re: Not that it stopped the BBC

If you'd read past the headline ,you'd have found that the first paragraph says "Smartphones running Google's Android software have been hijacked by an illegal botnet, according to a Microsoft researcher."

So, the article is saying that a Microsoft researcher has said there is an Android botnet. That much is actually true. A Microsoft researcher HAS stated there is Android based botnet.

I would personally be surprised if there wasn't. Think about it. While Google seems to do a good job of deleting malware from the official Google Play market, a lot of Android handsets don't have access to that store, and where they do have an app store, the people running it may not be as careful to check for malware as Google or Apple.

Look at the advantages. Most phones are connected to the network for most of the day. Also, Anti Malware software is relatively rare (compared to PCs, where most people seem to have some sort of anti malware system). Even where people have such software, a lot of apps on mobiles require some sort of network access, so people won't question when an app asks for network access.

I am not saying that Android botnets exist. I don't know if they do. I am saying they are likely to appear, if they haven't already. I am also saying that these botnets probably won't be limited to one Mobile OS. Even with Apple's checking, we've had the odd malware appear on the iOS App Store, and there are probably vulnerabilities within the OS that enable installation of malware.

Re: Kaspersky say on BOTH Google PLAY and Apple store

And that has nothing to do with this report... it's not even email.

But what Kapersky says about that one is very entertaining: "There is one more curious detail about Fidall. You can find in the code such magic hexadecimal values as '0xBEEFDEAD' or '0xFACEDEAD' (see screenshot below).e been noticed in different malicious applications."

I use DEADBEEF all the time for "magic" values as do many other packages and even computer systems (Amiga comes to mind). FEE1DEAD is also used in the linux kernel! Nothing malicious about it.

It's a laughable attempt by Kaspersky at making it seem worse than it is.

"While it is true in traditional email transactions that headers can be forged, I am not aware of any method to do this using Yahoo!'s API or web interfaces."

"One of the interesting data points supporting the argument that this is new Android malware is the unusually large number of the originating IPs on cellular networks."

Cellular networks? That thickens the plot a little bit.

Re: More news from Sophos

Yeah I was thinking Mobile Operator IP's should be a good indicator but... 90% of the time my droidphone is on a wifi connection of some sort and I'm sure I'm far from being the only one, so is it really a reliable indicator or a red herring / FUD / smokescreen.

There may well be a botnet that can use droidphones of course but that it originated from Microsoft is a key dodgy factor, the BBC spouting tech drivel verbatim is no help and, sadly, par for the course for them.

I'm sure google will have requested these alleged emails from the MS PR department for analysis by now so we'll have to wait and see I spose.

Google is copying Apple here

By sticking their head in the sand and denying this before they've even had the time to look into it. Whether or not there is an Android botnet in this particular instance, there is certainly no reason such a thing isn't possible via either a malicious app or good free app where the author decides after several updates that get it onto a million phones that he wants to make a bit of extra cash.

People rightly complain about Apple's "ignore it and it will go away" attitude towards security threats on OS X, which the flashback trojan recently proved to be stupid. Funneling everything through the app store and requiring review may make iOS somewhat more secure from app threats than Android, but it's not foolproof. OS X and Android be based on Unix gives them better security, but certainly not perfect security.

The default response to any accusations of malware on smartphone OSes should be "we will work with the reporter of this issue to determine if its a real threat and make a public statement when we know, with a follow up plan of action if it is found to be true." Sadly Microsoft may be ahead of both Android and iOS in this regard since they'd already had their wakeup call on PC security a decade ago.

The usual boring FUD

Microsoft did this (a bucket load of FUD) with Linux and now Android.

Just checked my spam folder and reviewed the headers of one such email and the IP was in a range as stated for "Individual PPPoE customers" owned by a Russian ISP offering a wide range of data services (including a DSL service). So, not a mobile IP, but still one that can be used by smartphones (wifi).

I sent two emails from Yahoo (one from my Android and another from Yahoo! Webmail) and compared the raw emails (including headers) to the spam mail (I got curious when I found one of these mails in my spam folder). The emails are made to look like they are sent by Yahoo Mail's Android app (probably using whatever API the official app does), but they in fact aren't. There's a flaw by the programmer (one I won't mention as otherwise they will correct it). The spam could have been sent from any OS - Windows, Linux, OS X, iOS, etc. Who knows. M$'s "researchers" should take more care when comparing the raw emails.
