One Year Of Lulz (Part II)
Christmas has just gone and here it is my personal way to wish you a Happy New Year: the second part of my personal chart (first part here) of Main 2011 Cyber Attacks covering the time window from August to November 2011 (December is not yet finished, and featuring remarkable events, so expect an update very soon). This memorable year is nearly over and is time, if you feel nostalgic, to scroll down the second part of the list to review the main Cyber Events that contributed, in my opinion, to change the landscape and the rules of the (information security) game. Many events in this period among whom, IMHO, the most noticeable is the one carried on against Diginotar. Since then our trust in conventional authentication models is not (and will not be) the same anymore.
Of course this is my personal selection. Suggestions are well accepted and if you need more details about the cyber events in 2011, feel free to consult my 2011 Cyber Attacks Master Index. As usual after the page break you find all the references…
Mobile Antiviruses: Malware Scanners or Malware Scammers?
Few days ago Juniper Networks has released a report on the status of Android Malware. The results are not encouraging for the Android Addicted since they show a 472% increase in malware samples since July 2011 (see the infographic for details).
This does not surprising: already in May in its annual Malicious Mobile Threats Report, report, Juniper had found a 400% increase in Android malware from 2009 to the summer of 2010. This trend is destined to further grow since the Juniper Global Threat Center found that October and November registered the fastest growth in Android malware discovery in the history of the platform. The number of malware samples identified in September increased by 28%. whilst October showed a 110% increase in malware sample collection over the previous month and a noticeable 171% increase from July 2011.
As far as the nature of malware is concerned, Juniper data show that the malware is getting more and more sophisticated, with the majority of malicious applications targeting communications, location, or other personal information. Of the known Android malware samples, 55%, acts as spyware, 44%, are SMS Trojans, which send SMS messages to premium rate numbers without the user’s consent.
The reason for this malware proliferation? A weak policy control on the Android market which makes easier for malicious developers to publish malware applications in disguise. From this point of view, at least according to Juniper, the model of Cupertino is much more efficient and secure.
Easily predictable Google’s answer came from the mouth of Chris DiBona, open source and public sector engineering manager at Google. According to DiBona, Open Source, which is widely present in all the major mobile phone operating systems, is software, and software can be insecure. But Open Source becomes stronger if it pays attention to security, otherwise it is destined to disappear. In support of this statement he quotes the cases of Sendmail and Apache, whose modules which were not considered enough secure disappeared or came back stronger (and more secure) than ever.
But DiBona’s does not stop here (probably he had read this AV-test report which demonstrates that free Android Antimalware applications are useless): “Yes, virus companies are playing on your fears to try to sell you bs protection software for Android, RIM and IOS. They are charlatans and scammers. IF you work for a company selling virus protection for android, rim or IOS you should be ashamed of yourself.”
From this point of view Google hopes that Ice Cream Sandwich will lead Android Security at the next level even if some features are raising security concerns among Infosec professionals.
Riot In Motion
As an (in)direct consequence of the London Riots, a crew of hackers called TeaMp0isoN has defaced the The Official BlackBerry Blog after RIM has indicated to assist London police, who are investigating the use of the messaging service in organizing riots, with a “very extensive monitoring of the BlackBerry Messenger model”.
The availability of BBM (Black Berry Messenger), a closed messaging system for one-to-one or one-to-many (encrypted!) communications at no charge, has made BlackBerry a very popular device among U.K. teens, who are believed to be the major responsible for the riots which have hit British streets. As a consequence BlackBerry Messenger is believed to have played a key role for rioters to organize themselves.
Since the Company decided to support the Police to contain the riot, granting access to BBM data and logs, it did not take so long for a resounding retaliation by the above quoted hacker group.
Curiously shortly after the attack, MP called for BlackBerry Messenger suspension to calm UK riots, and albeit this is claimed as a victory from rioters, I cannot help but notice that it is really a paradox: the whole story is a consequence of the need for authorities to extensively monitor BBM and the same authorities now ask for a complete lockdown of BBM which might be the ultimate remediation to stop the riots).
In my opinion, this hactivism event can be seen from a double perspective: at first glance this is only the last episode of hactivism, whose actions and impacts are nowadays natural extensions in the fifth virtual domain for wars and revolutions crossing the borders of the real world. But a second deeper analysis shows surprising and, somewhat, unexpected consequences.
The event was a consequence of the attempt by authorities to deprive rioters of their weapons, that is mobile technologies. Said in simple words, we are seeing a kind of Consumerization of Riots (the western world equivalent of what I defined Consumerization of Warfare that is the influence played by consumer technologies, mobile and social networks in primis, for spreading the riots in Middle East). Of course with the obvious difference of scopes and geography.
But if the contemporary use of both mobile technologies, for communicating and coordinating, and Social Media for virally spreading information useful for the cause (tweets like weapons), is a (quite) common and consolidated practice whose primary role has been recognized for the revolutions of Maghreb and Middle East, what is completely new is, for the first time, the impact and the price (to be) paid by the technology vendor, in this case RIM, (in)directly involved in the events. As a matter of fact RIM is suffering heavy aftermaths, which will not likely end here.
Not only the Waterloo based company was hacked with a resounding defacement, with huge consequences in terms of image, but also the brand seriously risks to be negatively associated with rioters, which could lead to further negative impacts for the brand, with possible consequences in terms of sells.
Is this maybe the reason why Twitter refused to shut down the accounts of the London rioters, besides the blog post according to which Tweets must always flow?
P.S. From an Information Security Perspective…
Several Information Security blogs were wondering if hackers managed to post on BlackBerry’s blog because of a software vulnerability, or because one of their administrators had his password cracked. In my opinion several tweets from TeaMp0isoN seems to confirm the first hypothesis:
(Other) Chronicles Of The Android
I know it is late and I am quite tired after a day of work. Still few seconds (and energies) to comment a new Gartner Report confirming what previously indicated by ABI Research and IDC, according to which, the Google Creature will command Nearly Half of Worldwide Smartphone Operating System Market by Year-End 2012.

In my opinion it worths noticing the inevitable fall of Symbian, the slow but inexorable descent of RIM, and the equally slow growth of Microsoft wich will be able to nearly touch the 20% only in 2015.
The android has every reason to celebrate and nothing better do it properly than this video in which an HTC Desire solves a dodecahedron Rubik’s Cube: an HTC desire runs a custom Android app which uses the phone’s camera to take individual images of each of the puzzle’s 12 faces, then processes the information and sends a signal via Bluetooth to the NXT controller,
What if Android Reassembles The Puzzle?
ComScore has just published its Press Release related to February 2011 U.S. Mobile Subscriber Market Share. 69.5 million people in the U.S. owned smartphones during the three months ending in February 2011, up 13 % from the preceding period. As we have become accustomed to a few months, the Android is still on the top, earning 7 percentage points since November 2010, achieving a 33% market share. RIM ranked second with 28.9 percent market share, followed by Apple with 25.2 percent. Microsoft (7.7 %) and Palm (2.8 %) rounded out the top five.

Considering the market share on a per-vendor base, provides a different interpretation, and explains some strategic mobile choices of the Mountain View giant. Among the OEM, Samsung ranked at the #1 with 24.8% of U.S. mobile subscribers, up 0.3 percentage points from the previous three month period. LG ranked #2 with 20.9 percent share, followed by Motorola (16.1 %) and RIM (8.6 percent). Apple saw the strongest gain, up 0.9 percentage points to account for 7.5 percent of subscribers.

I am not new to this kind of considerations (already faced in a previous post in Italian), but it is clear that the Android Landscape is becoming a little bit too much fragmented, and this risks to be a serious issue for the Android, both in terms of consumers’ perception, both in terms of security. As far as the consumer perception is concerned: many vendors are pushing more and more customizations not only on their own Android ROMs, but even on the services provided to consumer (read vendor-dedicated markets and services). This sounds confusing for the consumer who will inevitably ask why should he consider, inside the same platform, different parameters of choice external to the mere features of the devices (and how they map to consumer’s need). Not to mention also the tragedy of software updates: a new major release of the Android may take also one year to be ported in some devices, because of the wide customizations made by the manufacturers on their smartphones.
As far as security considerations are concerned, customization affects platform (in)stability and, inevitably security, if it is true that the same code must be adapted to run on different architectures, and security bugs are always behind the door.
These factors are probably behind the rumors claiming that Google has been demanding that Android licensees abide by “non-fragmentation clauses” that give Google the final say on how they can tweak the Android code, to make new interfaces and add services, and also behind the (not confirmed) rumors of standardizing the ARM Chip for Android 3.0. If we sum up these rumors with the fact the Mountain View will not (at least initially) release the Honeycomb Source Code, it looks clear that Google is running for cover in order to stem the excessive number of fragments in which OEM vendors are reducing its precious Android.
The Android is winning the market share battle against Apple and RIM, and forecasts for the next years show a bright future for the Android, destined to achieve nearly the half of the market in 2015. So far the Mountain View Strategy has shown to be winning, but the only obstacle, in this triumphant ride, could by represented by fragmentation, which might drive consumers to the monolithic models of Cupertino and Waterloo.
Chronicles Of The Android
The title of this post recalls a science fiction novel, but actually summarizes well a couple of news concerning the Android, which bounced in these days. Even if they seem apparently disjoined I decided to insert them in the same post: there is a logical link which connects the commercial success of a platform and the attention it attracts by malicious, and this seems to be the destiny of Android, to which the market share reserves a bright future, which become much less bright if one considers the information security consequences.
Part 1: Smartphone Market Share
This seems to be the right time for predictions as far as the smartphone market is concerned, that is the reason why I really was enjoyed in comparing the projections of ABI Research (released today), with the ones released from IDC a couple of days ago. The results are summarized in the following tables. Even if they are targeted at different years in the near future (respectively 2016 for ABI Research and 2015 for IDC), comparing the two reports is interesting for imaging what the future of the smartphone Operating System will be.
| ABI Research | IDC | |||||
| Operating System | 2010 | 2016 | Operating System | 2011 | 2015 | |
| Android | 23,00% | 45,00% | Android | 39,50% | 45,40% | |
| RIM | 16,00% | 14,00% | RIM | 14,90% | 13,70% | |
| iOS | 15,00% | 19,00% | iOS | 15,70% | 15,30% | |
| Symbian | 36,00% | - | Symbian | 20,90% | 0,20% | |
| Windows Phone 7/Windows Mobile | 0,60% | 7,50% | Windows Phone 7/Windows Mobile | 5,50% | 20,90% | |
| Others | 9,40% | 14,50% | Others | 3,50% | 4,60% | |
Often the providers of market intelligence do not agree on anything, but in this case, if there is one thing that seems to have no doubt, is the scepter of the Android, which seems to be destined, for both reports, to rule the market with nearly one half of the total smartphones shipped after 2015. The data also confirm a stable position for RIM (around 13%-14%), while do not completely agree as far as Apple is concerned, for which ABI research estimates a market share of 19% in 2016 and IDC a market share of 15% in 2015. But were the data are surprisingly different, is on the Windows Phone Market Share. According to ABI Research, Windows Phone will reach the 7% of the market (which become 7.5 adding the market share of its predecessor Windows Mobile). Unfortunately I do not think that, according to Microsoft’s hopes, the number 7 which identifies the mobile operating system series, pertains to the market share in 2016. Last and (unfortunately) least? IDC is more optimistic and foresees a bright future for Redmond in the mobile arena, with its creature ranking immediately behind the Android with the 20% of the market. Will be very amusing to see (in 5 years if we will remember) who was right.
Last and (unfortunately) least, the poor Symbian, sacrificial victim of Nokia and Microsoft agreement, which, in 5 years will remain little more than a romantic remembrance for mobile lovers, while, surprisingly, ABI research foresees a surprising 10% market share for Samsung Bada in 2016.
Part 2: Mobile Malware Market Share
Of course I am an infosec guy so I wonder if also the mobile malware will follow the same trend. This consideration arises from an interesting article I found in the Fortinet blog. Of course data must be taken with caution, but I could not help noticing that when one switches from smartphone market share to mobile malware market share, the ranking positions are reversed: over 50% of mobile malware families detected by the security firm concern Symbian, approximately 15% are Java ME midlets, while the Android approximately suffers only of the 5% of the infections. Of course, as correctly stated on the article, this does not means that Symbian is the less secure. In my opinion the bigger percentage of mobile malware is a simple consequence of the fact that Symbian is still the Operating System with the greater spread. Of course malware writers deserve bigger attention to those platforms which offer the wider attack surface (that is the wider possibility to spread infections). And in this moment, Symbian is an attractive prey from this point of view. My sixth sense (and one half as we say in Italy) says that the Android will not take a long time in order to achieve also the unenviable first position also in the mobile malware market share, not only because it is spreading at an incredible speed, but also because it is becoming an enterprise platform (so the value of the data stored are much more attractive for Cyber Crooks.
As if on purpose, today Symantec discovered yet another malware for Android (Android.Walkinwat), which, at least for this time, tries to discipline users that download files illegally from unauthorized sites. Analogously to some of its noble malware predecessors (Geinimi, HongTouTou, Android.Pjapps), the malware is hidden inside a non-existent version of a true application (in this case Walk and Text) and downloaded from parallel markets from Asia and United States, but instead of stealing private data, simply floods of SMS the contacts.
Hey, just downloaded a pirated App off the Internet, Walk and Text for Android. I am stupid and cheap, it costed only 1 buck. Don’t steal like I did.
At the hand, after sending the SMS (affecting the user’s phone bill) it warns the user with the following message.
Unfortunately downloading malware from Asian parallel market is not new, and it is not a coincidence that the same report from Fortinet indicates that most mobile malware families are implemented by Russian or Chinese coders. This is undoubtely an increasing trend, and I am afraid that Chinese coders will soon shift their Cyber Espionage Operations to mobile devices…
