Lizamoon: A Serious SQL Injection Attack

According to some security experts, Lizamoon is the most successful SQL injection attack ever witnessed.  During its short lifespan it has already compromised hundreds of thousands of websites.  While reports vary on the number of infected sites, some put the number over four million.  But these sites aren’t even the real victims; they’re just pawns in a larger scareware plot to steal people’s money.

It all starts when a line of java script is surreptitiously injected into a webpage’s code. The script redirects the website’s visitors to a rogue AV site that initiates what appears to be a comprehensive anti-malware scan on the victim’s computer.  The scan finishes up rather quickly (certainly faster than any legitimate computer scan would take) and alerts victims that their computers have been infected with Trojans, worms, and other malware.
The victims are then prompted with an option to “remove” the malware by downloading a “malware-removing” executable.  At this point, those who have been duped into downloading the fraudulent software program, which is called “Windows Stability Center,” receive offers to purchase additional software that will allegedly remove the malware from their computers.
Recently, it was reported that the SQL injection redirects are ineffective because the compromised websites have been shut down.  Regardless, we should all keep an eye on Lizamoon because it has already proven itself to be a formidable threat.

As one computer security blog points out, Lizamoon is easily avoidable with a little bit of common sense.  The simple solution is to not download any unknown files.  For a bit of added security, it’s wise to become familiar with your computer’s existing antivirus software.  If you know what it’s called and what it looks like, you’ll be able to recognize a fake when it rears its ugly face.

A Graphics Processing Unit (GPU)

A graphics processing unit (GPU) is a computer chip that performs rapid mathematical calculations, primarily for the purpose of rendering images. A GPU may be found integrated with a central processing unit (CPU) on the same circuit, on a graphics card or in the motherboard of a personal computer or server. In the early days of computing, the CPU performed these calculations. As more graphics-intensive applications such as AutoCAD were developed; however, their demands put strain on the CPU and degraded performance. GPUs came about as a way to offload those tasks from CPUs, freeing up their processing power. NVIDIA, AMD, Intel and ARM are some of the major players in the GPU market. GPU vs. CPU A graphics processing unit is able to render images more quickly than a central processing unit because of its parallel processing architecture, which allows it to perform multiple calculations at the same time. A single CPU does not have this capability, although multi...

What's the difference between two-step verification and 2FA?

  The two terms, two-step verification, and two-factor authentication are synonymous, though the former is now being used more widely by the likes of Google, Microsoft, and Apple as it better conveys how the actual authentication process works. In the past, two-step verification was used to describe processes that used the same authentication factors, while two-factor authentication described processes that involved different factors, such as entering a password on a website and receiving a numerical code on a mobile device. Today, the two terms are both used to describe authentication that involves a secondary factor that is different from the first. Authentication is a vital element of access control and data security because users can be assigned access rights and be authorized to perform certain actions only after successful authentication is performed. The ways in which someone can be authenticated fall into three categories based on what is known ...

Black Swan Event

A black swan event is an incident that occurs randomly and unexpectedly and has wide-spread ramifications. The event is usually followed with reflection and a flawed rationalization that it was inevitable. The phrase illustrates the frailty of inductive reasoning and the danger of making sweeping generalizations from limited observations. The term came from the idea that if a man saw a thousand swans and they were all white, he might logically conclude that all swans are white. The flaw in his logic is that even when the premises are true, the conclusion can still be false. In other words, just because the man has never seen a black swan, it does not mean they do not exist. As Dutch explorers discovered in 1697, black swans are simply outliers -- rare birds, unknown to Europeans until Willem de Vlamingh and his crew visited Australia. Statistician Nassim Nicholas Taleb uses the phrase black swan as a metaphor for how humans deal with unpredictable events in his 2007...
