Are you a malware developer for Android devices? We have very bad news for you: the Android-SDK packager (aapt) is leaking your time zone! We have found a bug inside this Android-SDK's component that relies in not properly setting the value of a vari

Google Play Store provides thousands of applications for monitoring your children/family members. Since these apps deal with highly sensitive information, they immediately raise questions on privacy and security. Who else can track the users? Is this

Pre-installed apps and firmware pose a risk due to vulnerabilities that can be pre-positioned on a device, rendering the device vulnerable on purchase. This means that the vulnerabilities are present even before the user enables wireless communicatio

In today's digital world the mouse, not the pen is arguably mightier than the sword. Via a single click, countless security mechanisms may be completely bypassed. Run untrusted app? click ...allowed. Authorize keychain access? click ...allowed. Load

With the proliferation of Linux-based SoCs -- you've likely got one or two in your house, on your person or in your pocket -- it is often useful to look "under the hood" at what is running; Additionally, in-situ debugging may be unavailable due to re

Regarding ptmalloc2, many heap exploitation techniques have been invented in the recent years, well documented on the famous how2heap repository, or as writeups of famous CTF challenges (like House of Orange). However, most of them require atleast a

Pre-installed apps and firmware pose a risk due to vulnerabilities that can be pre-positioned on a device, rendering the device vulnerable on purchase. This means that the vulnerabilities are present even before the user enables wireless communicatio

Security researchers have done a good amount of practical attacks in the past using chosen plain-text attacks on compressed traffic to steal sensitive data. In spite of how popular CRIME and BREACH were, little was talked about how this class of atta

In the ever raging battle between malicious code and anti-malware tools, firewalls play an essential role. Many a malware has been generically thwarted thanks to the watchful eye of these products.

However on macOS, firewalls are rather poorly unde

So how do you debug bios and triage a vulnerability for exploitability with no stack trace or error log? How do BIOS developers do it? Do not worry! We will explain how anyone can have debug capabilities on modern Intel platforms and show you how thi

The arbiters of defense wield many static analysis tools; disassemblers, PE viewers, and anti-viruses are among them. When you peer into their minds, these tools reveal their perilous implementations of PE file parsing. They assume PE files come as-i

Barcodes and barcode scanners are ubiquitous in many industries and work with untrusted data on labels, boxes, and even phone screens. Most scanners also allow programming via barcodes to manipulate and inject keystrokes. See the problem? By scanning

Voicemail systems have been with us since the 80s. They played a big role in the earlier hacking scene and re-reading those e-zines, articles and tutorials paints an interesting picture. Not much has changed. Not in the technology nor in the attack v

First of all, it's math. Not meth. So everybody be cool, I'm not gonna touch your central nervous system stimulant substances. Now that this is established, I can start telling my story. And this story, like all good stories, begins where it ends.

Commercial Android emulators such as NOX, BlueStacks and Leidian are very popular at the moment and most games can run on these emulators fast and soundly. The bad news for game vendors is that these emulators are usually shipped with root permission

When caching servers and load balancers became an integral part of the Internet's infrastructure, vendors introduced "Edge Side Includes" (ESI), a technology allowing malleability in caching systems. This legacy technology, still implemented in nearl

These days it's hard to find a business that doesn't accept faster payments. Mobile Point of Sales (mPOS) terminals have propelled this growth lowering the barriers for small and micro-sized businesses to accept non-cash payments. Older payment techn

Extreme network's embedded WingOS (Originally created by Motorola) is an operating system used in several wireless devices such as access points and controllers. This OS is being used in Motorola devices, Zebra devices and Extreme network's devices.

Software-Defined Networking (SDN) is now widely deployed in production environments with an ever-growing community. Though SDN's software-based architecture enables network programmability, it also introduces dangerous code vulnerabilities into SDN c

Financial institutions, home automation products, and offices near universal cryptographic decoders have increasingly used voice fingerprinting as a method for authentication. Recent advances in machine learning and text-to-speech have shown that syn
