    Steganography will only become more popular, especially among the more industrious malware groups out there. For an attacker, the ability to hide stuff in plain sight is like peanut butter on chocolate: it makes their favorite thing even better. In the first two entries of this series, we explored which steganographic techniques are used by attackers to keep malware from being detected, and how they are used to hide command-and-control (C&C) commands, as well as executable code. This time, we’ll discuss the impact of ...

    For the past couple of days the security industry has been discussing claims that the systems of a commercial aircraft was "hacked" via the on-board inflight entertainment system (IFE). This became public after a search warrant was obtained by media outlets which revealed that the Federal Bureau of Investigation had applied for a search warrant targeting Chris Roberts, a researcher looking into airplane security.

Even the macro threats that were supposedly long gone are now back in the wild. Today’s threats leave zero room for error. For instance, we saw a surge ...

    In our earlier post discussing steganography, I discussed how it is now being used to hide configuration data by malware attackers. Let's go discuss this subject another facet of this topic in this post: how actual malware code is hidden in similar ways. Security analysts will probably throw their hands up in the air and say, "we've had code hiding within code for years now, that's not steganography!". That's not what I'm talking about. I will talk about how steganography is used with seemingly innocuous data files ...

    In the first part of this series, we discussed about the macro malware we have recently seen in the threat landscape. This second entry will delve deeper into the techniques or routines of macro malware. Unintended consequences Let us put things into perspective – by itself, macros are not harmful to the user. Its intended function is to automate frequently used tasks. The problem lies when cybercriminals abuse the functionalities of macro code to execute malicious routines. Microsoft offers macro protection  within the Microsoft ...
