#WannaCry: Examining Weaponized Malware

Attribution: You Keep Using That Word, I Do Not Think It Means What You Think It Means… In internal discussions in virtual halls of IOActive this morning, there were many talks about the collective industry’s rush to blame or attribution over the recent WanaCry/WannaCrypt ransomware breakouts. Twitter was lit up on #Wannacry and #WannaCrypt and even Microsoft got into the action, stating, “We need governments to consider the damage to civilians that comes from hoarding these vulnerabilities and the use of these exploits.” Opinions for blame and…

Is Stegomalware in Google Play a Real Threat?

For several decades, the science of steganography has been used to hide malicious code (useful in intrusions) or to create covert channels (useful in information leakage). Nowadays, steganography can be applied to almost any logical/physical medium (format files, images, audio, video, text, protocols, programming languages, file systems, BIOS, etc.). If the steganographic algorithms are well designed, the hidden information is really difficult to detect. Detecting hidden information, malicious or not, is so complex that the study of steganalytic algorithms (detection) has been growing. You can see the growth in scientific…

Hackers Unmasked: Detecting, Analyzing, And Taking Action Against Current Threats

Tomorrow morning I’ll be delivering the opening keynote to InformationWeek & Dark Reading’s virtual security event – Hackers Unmasked — Detecting, Analyzing, And Taking Action Against Current Threats. You can catch my live session at 11:00am Eastern discussing the “Portrait of a Malware Author” where I’ll be discussing how today’s malware is more sophisticated – and more targeted – than ever before. Who are the people who write these next-generation attacks, and what are their motivations? What are their methods, and how do they chose their targets? Along with how…

Offensive Defense

I presented before the holiday break at Seattle B-Sides on a topic I called “Offensive Defense.” This blog will summarize the talk. I feel it’s relevant to share due to the recent discussions on desktop antivirus software   (AV) What is Offensive Defense? The basic premise of the talk is that a good defense is a “smart” layered defense. My “Offensive Defense” presentation title  might be interpreted as fighting back against your adversaries much like the Sexy Defense talk my co-worker Ian Amit has been presenting. My view of…

The Demise of Desktop Antivirus

Are you old enough to remember the demise of the ubiquitous CompuServe and AOL CD’s that used to be attached to every computer magazine you ever brought between the mid-80’s and mid-90’s? If you missed that annoying period of Internet history, maybe you’ll be able to watch the death of desktop antivirus instead. 65,000 AOL CD’s as art Just as dial-up subscription portals and proprietary “web browsers” represent a yester-year view of the Internet, desktop antivirus is similarly being confined…

SexyDefense Gets Real

As some of you know by now, the recent focus of my research has been defense. After years of dealing almost exclusively with offensive research, I realized that we have been doing an injustice to ourselves as professionals. After all, we eventually get to help organizations protect themselves (having the mindset that the best way to learn defense is to study the offensive techniques), but nevertheless, when examining how organizations practice defense one has a feeling of missing something. For far too long the practice (and art?) of defense has…

Inside Flame: You Say Shell32, I Say MSSECMGR

When I was reading the CrySyS report on Flame (sKyWIper)[1], one paragraph, in particular, caught my attention:   In case of sKyWIper, the code injection mechanism is stealthier such that the presence of the code injection cannot be determined by conventional methods such as listing the modules of the corresponding system processes (winlogon, services, explorer). The only trace we found at the first sight is that certain memory regions are mapped with the suspicious READ, WRITE and EXECUTE protection flags, and they can only be grasped via…

Arm IDA and Cross Check: Reversing the 787’s Core Network

IOActive has documented detailed attack paths and component vulnerabilities to describe the first plausible, detailed public attack paths to effectively reach the avionics network on a 787, commercial airplane from either non-critical domains, such as Passenger Information and Entertainment Services, or even external networks.
