Stories about electronic skimmers and identity theft are definitely not something new in our world today — as a matter of fact they are a daily occurrence. The availability of credit card skimmers for a really cheap price and the profit made when an identity is sold make this a very lucrative business. In the current economy people seem to be using this business model to earn extra money as indicated by these stories on the FBI [U.S. Federal Bureau of Investigation] website.

  • Watch out for Fake Virus Alerts
    State of West Virginia Cyber Security Tip ALERT West Virginia Office of Information Security and Controls – Jim Richards, WV Chief Information Security Officer WATCH OUT FOR FAKE VIRUS ALERTS Rogue security software, also known as "scareware," is software that appears to be beneficial from a security perspective (i.e. free virus scan) but provides limited or no security, generates erroneous or misleading alerts, or attempts to lure users into participating in fraudulent transactions. How does rogue security software get on my computer? Rogue security software designers create legitimate looking pop-up windows that advertise security update software. These windows might appear on your screen while you surf the web. The "updates" or "alerts" in the pop-up windows call for you to take some sort of action, such as clicking to install the software, accept recommended updates, or remove unwanted viruses or spyware. When you click, the rogue security software downloads to your computer. Rogue security software might also appear in the list of search results when you are searching for trustworthy antispyware software, so it is important to protect your computer. What does rogue security software do? Rogue security software might report a virus, even though your computer is actually clean. The software might also fail to report viruses when your computer is infected. Inversely, sometimes, when you download rogue security software, it will install a virus or other malicious software on your computer so that the software has something to detect. Some rogue security software might also: Lure you into a fraudulent transaction (for example, upgrading to a non-existent paid version of a program).

  • Detecting Botnets Using File System Indicators
    Detecting botnets using file system indicators Master's thesis University of Twente Author: Committee members: Peter Wagenaar Prof. Dr. Pieter H. Hartel Dr. Damiano Bolzoni Frank Bernaards LLM (NHTCU) December 12, 2012 Abstract Botnets, large groups of networked zombie computers under centralised control, are recognised as one of the major threats on the internet. There is a lot of research towards ways of detecting botnets, in particular towards detecting Command and Control servers. Most of the research is focused on trying to detect the commands that these servers send to the bots over the network. For this research, we have looked at botnets from a botmaster's perspective. First, we characterise several botnet enhancing techniques using three aspects: resilience, stealth and churn. We see that these enhancements are usually employed in the network communications between the C&C and the bots. This leads us to our second contribution: we propose a new botnet detection method based on the way C&C's are present on the file system. We define a set of file system based indicators and use them to search for C&C's in images of hard disks. We investigate how the aspects resilience, stealth and churn apply to each of the indicators and discuss countermeasures botmasters could take to evade detection. We validate our method by applying it to a test dataset of 94 disk images, 16 of which contain C&C installations, and show that low false positive and false negative ratio's can be achieved. Approaching the botnet detection problem from this angle is novel, which provides a basis for further research.

Security is all about knowing who and what to trust. It is important to know when and when not to take a person at their word and when the person you are communicating with & what they say who they are. 4 Security’s weakest link ? A company may have purchased – - The best security technologies that money can buy, - Trained their people so well that they lock up all their secrets before going home at night, and - Hired building guards from the best security firm in the business. That company is still totally vulnerable. 5 Security’s weakest link ? An Individuals may follow: - Every best-security practice recommended by the experts, - Slavishly install every recommended security products, - Be thoroughly vigilant about proper system configuration and - Apply various security patches regularly. Those individuals are still completely vulnerable . 6 Human Factor: Security’s weakest link • Anyone who thinks that security products alone offer true security is settling for the illusion of security.
