The Future of Mobile Malware – Digitally Signed by Symbian?

From ZDNet (Dancho Danchev)
Earlier this month, a mobile malware known as Sexy View or Sexy Space slipped through Symbian’s mobile code signing procedure, allowing it to act as a legitimate application with access to device critical functions such as access to the mobile network, and numerous other functions of the handset.
Upon notification, the Symbian Foundation quickly revoked the certificate used by the bogus Chinese company XinZhongLi TianJin Co. Ltd, however, due to the fact the revocation check is turned off by default, the effect of the revocation remains questionable. What are the chances that future malware authors could bypass the code signing procedure again?   Read the full story [zdnet.com]

Adobe Flash Attacks Underway; Harden PDF Reader Immediately

Malicious hackers have found a new vulnerability in Adobe’s ever-present Flash software and are using rigged PDF documents to launch exploits against Windows targets.

The Adobe Flash Player flaw, which is currently unpatched, affects millions of Windows XP and Windows Vista users.  Adobe has acknowledged a “potential vulnerability” but, inexplicably, has not seen it fit to warn of the zero-day attacks or issue pre-patch mitigation guidance to tens of millions of its customers.

The Economics of Botnets

From Viruslist.com (Yury Namestnikov)
In the past ten years, botnets have evolved from small networks of a dozen PCs controlled from a single C&C (command and control center) into sophisticated distributed systems comprising millions of computers with decentralized control. Why are these enormous zombie networks created? The answer can be given in a single word: money.
A botnet, or zombie network, is a network of computers infected with a malicious program that allows cybercriminals to control the infected machines remotely without the users’ knowledge.  So how does one start? What does a cybercriminal in need of a botnet do? There are many possibilities, depending on the criminal’s skills. Unfortunately, those who decide to set up a botnet from scratch will have no difficulty finding instructions on the Internet.  Read the full paper (viruslist.com)

The original iPhone was widely criticized by security professionals for lacking essential security features for the enterprise, the large corporate networks that have special needs because of huge numbers of users and the massive back-end operations to support those users.
The original iPhone was hard to lock down, had only limited secure connectivity options, and lacked both data protection and some way to destroy data remotely if you lost the phone. Those capabilities have continued to improve with every iPhone software release and, combined with the hardware improvements in the iPhone 3GS, even regular users can now enjoy security equivalent to that provided by most corporate environments.

From CNet News (Josh Lowensohn)
Microsoft is bringing out the big guns to combat instant message spam and phishing attacks done to users of its Live Messenger network. The Redmond, Wash.-based software giant filed a civil lawsuit Thursday in King County Superior Court in Seattle against Funmobile, Mobilefunster, and several individuals, who Microsoft says is responsible for the intentional misuse of the service to gain the personal information of its users.
In the suit (which is embedded below), Microsoft cites a multitude of attacks including IMs that appear to be coming from users they know, as well as phishing attacks that mimic the look and feel of an outside service, or an official Microsoft support page.

Earlier this week, I wrote about a “highly critical” — and unpatched — vulnerability that puts millions of Web surfers at risk of malicious hacker attacks. 
Since then, there has been word that the release of the vulnerability and exploit was “self-inflicted” (Mozilla exposed the bug themselves) and official instructions on how to mitigate the risks until a patch is ready.

Computerworld – Compared to other key corporate executives, CEOs appear to underestimate the IT security risks faced by their own organizations, according to a survey of C-level executives released today by the Ponemon Institute.

The Ponemon survey of 213 CEOs, CIOs, COOs and other senior executives reveals what appears to be a perception gap concerning information security issues between CEOs and other senior managers. For instance, 48% of CEOs surveyed said they believe hackers rarely try to access corporate data. On the other hand, some 53% of other C-level executives believe that their company’s data is under attack on a daily or even hourly basis.

Microsoft today released six bulletins with fixes for at least nine documented security vulnerabilities in a range of products that put users at risk of malicious hacker attacks.

At least two of the vulnerabilities are currently being attacked in the wild so it’s imperative that Windows users and administrators treat these patches with the highest possible priority.
