The Current State of CyberWar in the World

Drama. Drama is the touchstone for reporting. We have to look well around this particular stone in order to catch a realistic impression of the virtual. We have to look around it even to understand what CyberWar is or how it is defined.

When talking about cyberwar, hyperbole & metaphor are the rule rather than the exception. Cyberthis, cyberthat – you may have noticed that the virtual world is inhabited by nouns and verbs taken from the material world, and that images of cyberthings in the news tend to have dramatic pictures of physical things rather than the electrons that make up the cyberworld. Images of coins inhabit stories of purely virtual cryptocurrency, such as BitCoin. Perhaps Physics journals, where readers actually are interested in the electrons and the math of the cyberrealm, are the exception to this rule.

But when we read stories of cyberwar, we see pictures of soldiers, firearms and materiel accompanying the story. When we read of the people sitting at desks and computers to figure out how to hack and not be hacked, we call them CyberWarriors and pictures of men in flak jackets and helmets accompany these stories. I wonder what CyberItem will be accompanied by

Home Brewed Data Destruction

Law around the subject of electronically stored information (ESI) and computer forensics is ever-evolving. In a lawsuit, it’s treated just like paper documents. If you shred or burn the paper evidence, you’re in trouble – and if you’re caught deleting or wiping electronic evidence, you’re in the same boat.

But in some cases, it can be easier to get busted for destroying ESI, both because electrons have a way of proliferating as digital copies of files and pictures and documents, and because the process of destroying data usually leaves detectable digital traces.

Just yesterday, a fellow (I decline to call him a gentleman) called me up to ask if he could consult with me on an hourly basis about how to destroy data (evidence) on his computer for an upcoming potential divorce. I actually found myself offended and explained to him (trying to keep the disdain from my voice) that destroying evidence is the exact opposite of the service I offer.

We don’t wreck evidence – we find it.

I further suggested that he might want to look into the Federal Rules of Civil Procedure, Sections 26 & 34 and how they apply in his state. I told him that I am not an

How to Keep Anyone From Snooping Around Your Cloud

The American Civil Liberties Union, based in New York, NY., reported the U.S. Government claims the right to read personal online data without warrants. This trend is not unique to the U.S. Government. Many governments around the world make requests of these service providers as well.

According to statistics published by Google, it received over 16,000 requests for information affecting over 31,000 users in 2012. Google’s same statistics stated they provided information in over 85% of the requests.

In 2012 Microsoft received over 70,000 requests affecting over 120,000 accounts. While this is a much higher number, Microsoft only produced information on these requests about 2% of the time. Almost 80% of the requests asked Microsoft to divulged subscriber and transactional information only.

Locking the thieves out:
Companies and individuals can take easy steps to prevent thieves, companies and the government from gaining access to online storage which contains private information.

Here are a few basic ways of protecting or encrypting the data to keep prying eyes from viewing confidential and/or personal information:

1) The data can be encrypted before it is stored in the Cloud. Products like TrueCrypt, Privacy Drive and MyInfoSafe allow for the user to encrypt their data. This type of encryption can

Hacking Expert Witness: US Charges Eight in Hacking Scheme

This allegedly began in 2011, when several accounts in banks such as: Citibank, JP Morgan Chase, PayPal, the U.S. Military Defense Finance and 11 other banks had their accounts compromised. Once inside these accounts, the hackers setup a payment which was sent to several pre-paid debit cards. The pre-paid cards were then used by an accomplice (aka “cashers” or “money mules”) to make ATM withdrawals or purchases to convert the card into cash.

From here, the cashers took a small cut for themselves, while sending the bulk of the money to their employer via a wire transfer.

They managed to avoid detection for some time by keeping the transfers below the $10,000 threshold set by the anti-money laundering laws of the U.S. However, they routinely made payments of $9,900. A $10,000 transaction sends up a big red flag, a $9,900 transaction sends up a smaller red flag. It is these multiple $9,900 amount transfers along with a Gmail account the defendants use to talked with others about the scheme that was their downfall. In addition to the discussion about the scheme, there were many emails in this account that detailed the transfers to and from many of the banks. Currently only

Packet Capture – Definition and Importance

As the data keeps streaming by, sniffers capture each packet and decode them if needed showing the value of various field in the packet. The content then gets analyzed as per the specifications. The analysis helps in determining if there are unusual packets. This helps in maintaining effective data transmission.


A packet capture can be used in two ways- legitimately and illegitimately. In legitimate use, sniffing identifies the data and transmission errors to ensure an efficient network communication. However, in an illegitimate scenario, a disgruntled employee can use the data to actually ‘capture’ the company’s credit account information. Obviously, this information is not for any saintly purpose. He may use the information to transfer the company money to his own personal accounts!

Its Importance

The primary importance of packet sniffer is detection of network. A packet capture is similar to telephone wire tapping. It detects what is going through the computer networks. The main function of the software is to monitor the performance and troubleshoot the problems that may arise in a network. In addition, it can capture the traffic from different parts of the network using the software program. Sniffing data from just one part of the network may not be advantageous

Open Source Computer Forensics Investigations

The world of computer forensics — like all things computer — is rapidly developing and changing. While commercial investigative software packages exist, like EnCase by Guidance Software and FTK by AccessData, there are other software platforms which offer a solution for obtaining computer forensic results. Unlike the two aforementioned packages, these open sources alternatives do not cost hundreds of dollars — they are free to download, distribute and use under various open source licenses.

Computer Forensics is the process of obtaining information from a computer system. This information may be obtained from a live system (one that is up and running) or a system which has been shut down. The process typically involves taking steps to obtain a copy, or an image of the target system (often times an image of the hard drive is obtained, but in the case of a “live” system, this can even be the other memory areas of the computer).

After making an exact “image” or copy of the target, in which the copy is verified by “checksum” processes, the computer specialist can begin to examine and obtain a wide range of data. This copy is obtained through write protected means to preserve the integrity of the

Computer Forensics and Hacking Expert Witness

The most common visual is the pale nerd in his mother’s basement who is getting into his university server to change his rivals grades to failing ones. Then there are the various Hollywood depictions which show “master criminals” manipulating traffic signals and financial markets. This is a fairly recent use of the word “hacker” and for years before it had a very different meaning.

In the early 90’s when Linux (a popular free computer operating system) was introduced, the word hacker did not even exist. Users of these operating systems referred to themselves as “hackers”, only due to their ability to manipulate and reuse programming code for their own purposes, outside of its originally intended purpose. If you think of them as chefs, everyone has that one basic recipe for lobster bisque, but each chef will put their own spin on the recipe to make it their own. They were / are very competent programmers that had a passion for writing their own programs.

The majority of these “hackers” used their skills for good. For example, helping a friend who needed new software to help keep track of inventory at a grocery store. Then there are some more famous hackers, including Steve

Secure Your Web Application Like Your Own House

An easy way to view web application security is by picturing your own house. It has a front door, a back door, windows, a number of rooms, a roof, boundary fences and different access routes. Only the terminology is different.

The Front Door.
The front door of any web application is the login page and, not surprisingly, it is the primary point of attack. A login page will consist of edit boxes to type a user name and password and a button to send these for the server to authenticate your access to the rest of the web application. Some login pages may provide a captcha to make sure you are a human being and not a mock-up of the same form on a different server. The mock-up form will cycle through variations of user names and passwords until it gains access to the application. This is known as cross-site forgery and is akin to a burglar forging the keys to your house.

Captchas are jumbled images of scrambled letters and numbers which make it impossible for an automated script to read. Unfortunately, as the scripts become cleverer at reading these images, the captcha images need to become more complex and harder
