How Well Do You Understand Your Cyber Adversary? - Part 1

PAN-blue-2

This is a pet peeve of mine, but when I hear somebody from the cybersecurity community refer to a web-defacement as cyber warfare, my soul dies a little. Really? A hacktivist converts the corporate logo on a company web site into a Guy Fawkes mask and it's cyber warfare? Hardly.

A criminal steals customer credit card data from a retail database and we call that cyber terrorism? Not likely. A cyber spy steals a collection of intellectual property secrets and we call that a cyber crime? Yes, but while it’s a criminal offense to break into a corporate network, good-luck prosecuting a nation state that wants your secrets.

A Tale of 3 Vulnerabilities, CVE-2014-1776 Exploit Linked to Previous Attacks

Posted on by Bo Qu

Summary

  • The exploit code used in the recent CVE-2014-1776 attacks shares many similar characteristics with code that exploited CVE-2014-0322 and CVE-2013-3163.
  • The shared techniques, variable names and code structure suggest these exploits share a common author or template.
  • Palo Alto Networks customers are protected by from exploitation of CVE-2014-1776 with content release 433-2194.

Late last month reports surfaced that a new Internet Explorer vulnerability (CVE-2014-1776) was being exploited in targeted attacks. The vulnerability allows an attacker to take full control over the system after a user views a web page in their browser. According to Microsoft, it affects versions of Internet Explorer from version 6 to 11, meaning that almost all IE users are vulnerable to this bug. This vulnerability is so widespread that Microsoft has released patches to protect Windows XP, for which Microsoft has ended support since April 8, 2014.

Palo Alto Networks Protects Customers From Critical IE Vulnerability CVE-2014-1776

Posted on by Scott Simkin

Summary

  • Critical vulnerability (CVE-2014-1776) identified in Internet Explorer, with active attacks observed in the wild
  • IE vulnerability could be used to exploit multiple versions of Internet Explorer, including those on Windows-XP based systems, which no longer receive security updates from Microsoft
  • Palo Alto Networks Threat Prevention customers are protected from exploitation of the vulnerability
  • Cyvera endpoint solution specializes in preventing the type of exploitation behavior used in this attack

On Saturday, Microsoft disclosed a critical vulnerability in Internet Explorer, CVE-2014-1776, affecting Internet Explorer versions 6 through 11. The vulnerability exists in the way that Internet Explorer accesses an object in memory that has been deleted or has not been properly allocated.

Cardbuyer: New Smart Android Trojan Defeats Multi-factor Verification and Steals Prepaid Game Cards

Posted on by Claud Xiao

On April 21st our WildFire analysis cloud detected a new Android Trojan, which is currently completely undetected in VirusTotal and uses a new combination of tactics to make money for the author. Based on the state of the code and the limited distribution we believe we may have detected this malware during a testing phase, before the attacker released it into the wild through an app store or other means. We’ve named the Trojan Cardbuyer because of the way it converts an infection into cash for the author.

Cardbuyer is much “smarter” compared to the existing Android malware families that we have ever seen. Specifically, this malware sample can solve CAPTCHA challenges, emulate user’s behaviors, parse SMS’s content from different vendors, and then automatically reply the confirmation message accordingly. Code analysis shows that this malware sample can defeat the existing multi-factor verification procedures of many popular game platforms or online payment systems, and impersonate the smartphone user in making the purchase.

8 Tips For Dealing With Heartbleed Right Now

Posted on by Rick Howard

This has been a fun week. We have not had a significant cyber event like this – something that affects just about everybody on the Internet -- since the Kaminsky DNS vulnerability of 2008. Everybody I know has been scrambling to understand what it means to their organization, to their business and to their immediate family. Yes, I said family. I am sure I am not the only one who has answered a question or two from his mother-in-law about how the Internet is melting down based on what she’s been reading in the press.

There’s a lot out there already about what Heartbleed means for the Web and beyond, and I’ll point you to our own analysis written by Scott Simkin or an essay by Dan Goodin over at ars technica for that explanation. Instead, here are eight things I am doing right now to protect Palo Alto Networks and my home (and mother-in-law) and that you should be doing, too:
