Apple IPhone Accounts Hacked Using KeyRaider Malware

Palo Alto Networks and Weip Tech have uncovered a hack that involves over 225,000 Apple IPhone accounts so far. This hack is accomplished with a malware called KeyRaider on jailbroken IOs devices. It is reported that "the malware intercepts iTunes traffic to steal data from random user accounts, whose devices have been compromised through installation of malware-ridden jailbreak apps from untrusted sources." Compromised accounts could ultimately be charged with bogus purchases by the attacker. Here is a link to an article that explains how to detect if your device has the virus and how to remove it.

Memory Leaks and C, C++


I just wanted to review some quick facts about security architecture and design, more specifically memory leaks. Its concept you should be familiar with if you plan on taking the Security+, CISSP, etc.

Characteristics of Memory Leaks

When programs are written in object oriented programming languages programmers need to allocation memory space for each object that is created in the program. Once the object is no longer required by the program its memory space should be de-allocated to free up memory resources for the system to use. Some programming languages does leaves that to the programmer to accomplish herself. Other languages provide that capability automatically with a built-in garbage collector. When programs are poorly written with objects using up memory and never releasing the memory back to the system we call this a memory leak. The memory leaks are considered a vulnerability and if discovered by hackers they can be exploited to crash the system in a denial of service attack.

One thing to keep in mind about memory leaks is that they are common in languages that have no built-in automatic garbage collection. Languages such as C and C++ lack a built-in automatic garbage collector and leaves it to the programmer to manage memory allocation. Java, C#, Haskell and a host of other modern languages automatically get rid of objects that are no longer required by the application. It is encourage to use the programming languages that have garbage collection automatically. Even experienced programmers can have a memory bugs in a program that contain thousands of lines of code.

If you are taking the CISSP examination just remember that memory leaks are common in C, C++, and other languages that lack an automatic garbage collector and it is uncommon with Java, C#, and other languages that do have built-in garbage collection.

One Reason to Pay Cash at the Gas Pump

Today while I was at the gas pump I noticed a skimmer. I wanted to write about it to make you guys aware of this scam. To be safe its better to pay cash at the pump.

Certified Cloud Security Professional CCSP

I have decided to pursue a certificate in Cloud Security. All data and applications are living in the cloud now days. Pretty soon even the operating systems will be on the cloud too.

It's cool that (ISC)2 has teamed up with Cloud Security Alliance (CSA)to create the CCSP credential. I plan on doing consulting working in information security. This credential will definitely help me demonstrate my knowledge about cloud security.

Certified Information Security Professional

It's official, I'm a CISSP now. After several weeks of study and review, I took the exam for the first time and passed. I was sweating bullets that morning for six hours long thinking to myself that I failed the test. I was surprised to see the words "congratulation" on the piece of paper the proctors give out at the end of the exam. Too bad ISC2 does not give out a score--I really want to know how well I did on the exam. I felt like I did poorly but that might just be me being too hard on myself. I think I might have over studied for this test even.

One thing I would recommend to CISSP candidates is to consider free study guides first before spending thousands on training seminars. You can save money by self-studying. This is already an expensive exam to pay for. Now, if your employer is paying for your training then by all means take advantage of it. The reason I'm recommending for self-study is because the topics and sub-topics are not that complicated. This exam is a "mile wide and an inch deep". If you can find enough time to go over all the material thoroughly then you will most likely pass it.

To all those planning on taking the CISSP exam good luck.
