A new version of the Zeus botnet was used to steal about $47 million from European banking customers in the past year. This Zeus variant Trojan is blamed for attacks that stole more than 36 million Euros ($47 million U.S. dollars) from an estimated 30,000 consumer and corporate accounts at European banks. Dubbed "Eurograbber"  is more than just another banking Trojan. It's an exploitation of fundamental online banking authentication practices that could strike any institution. With the phone number and platform information, the attacker sends a text message to the victim's phone with a link to a site that downloads what it says is "encryption software" for the device. Customers become victims of Eurograbber by clicking on malicious links that may come in phishing-attack emails and then after injecting scripts to browser , the malware intercepts two-step authentication text messages sent to customers' phones. Customers at an estimated 30 banks fell vic...

Like many other security issues that now affect computer users, there is a growing threat known as phishing". Phishing attacks are perpetrated by criminals who send deceptive emails in order to lure someone into visiting a fraudulent web site or downloading malicious software, expressly for stealing sensitive information such as credit card numbers, account information, passwords, etc. Cyber criminals continue to evolve and refine their attack tactics to evade detection and use techniques that work. Spear phishing emails are on the rise because they work. We have notice many times that Spear Phishing Attacks are really Successful in order to compromise Enterprise Networks and Stealing Data. From last one month I was getting mails from an unknown spoofed email id regrading a paypal warning with subject " Your account has been limited until we hear from you !

A new trojan horse app called Dockster is targeting Mac users by exploiting a known Java vulnerability CVE-2012-0507. The trojan is apparently being delivered through a website (gyalwarinpoche.com) dedicated to the Dalai Lama and once installed can collect user keystrokes and other personal information. Mac in Danger ?  Earlier this spring, a Russian security firm discovered a trojan piece of malware which took advantage of a Java vulnerability on many computers, Macs and PCs alike. This trojan, known as “Flashback,” was used to enlist some 600,000 infected computers into a botnet. Malware also provides an interface that allows attackers to download and execute additional malware. Dockster has been found to use the same exploit code as the previous SabPab virus to gain access through a backdoor. Dockster is also said to launch an agent called mac.dockset.deman, which restarts each time a user logs in to their Mac. Dockster is only the latest Mac-bas...

Of course that is a very small myopic view of how being a white hat hacker really works but there is always going to be an element of that kind of thought out there. There are just a lot of people out there who believe that if you ban hacking outright that it will never be done. And that is simply just not true and is a pure fantasy. But if you really want to be a good and effective white hat hacker, then there are some elements about the other side that you should really get to know. If you want to be able to beat your enemies then you should be able to figure out how they operate. It is not enough for you to be able to take a look at their attacks and try to study their patterns...
