An Iranian hacker published the information about some 3 million debit cards of 10 Iranian banks, including codes and passwords. The information has been published by someone named “Khosrow Zare Farid” who was the manager of a company which operates SHETAB payment network in Iran and produces and installs POS devices. “Around one year ago I found a critical bug in the system. Then I wrote and sent a formal report to all the CEO of banks in Iran but none of them replied to me. Now I decided to publish the information. Governments tried to catch me by Iran Cyber Army but they failed,” he said, according to Kabir News website ...

Anti-virus experts at Trend Micro have discovered ransomware which blocks systems from booting. In contrast to the localised trojans, which are widely spread around Europe, it does so by inserting itself into the master boot record (MBR). It then restarts the system and instructs the user to pay a ransom of 920 Ukrainian hryvnia (equivalent to about 90 euros) to the criminals via payment service QIWI. If victims pay up, the criminals send them a code to unlock their computers. Users can, however, save themselves 920 hryvnia by following the experts’ instructions for removing the infection. This essentially consists of running the recovery console from the Windows Installation DVD and restoring the original MBR using the fixmbr command. ...

The H-Online: As expected, Apple has released an updated version of the Java implementation for its Mac OS X operating system that includes a removal tool for the Flashback trojan. According to the company, the update, labelled “Java for OS X 2012-003“, finds and removes the “most common variants” of the malware which had infected approximately 600,000 systems using flaws in the previous version of Java. Additionally, the new Java update for Mac OS X 10.7 Lion prevents Java applets from being automatically executed by disabling the Java web plugin by default. Users can re-enable the automatic execution of Java applets via the Java Preferences application (Applications ➤ Utilities ➤ Java Preferences). However, if the plugin detects that Java applets have not been run for “an extended period of time”, it will automatically disable applet support again. ...

Android malware authors have seized an opportunity to infect unsuspecting smartphone users with the launch of the latest addition to the immensely popular “Angry Birds” series of games. SophosLabs recently encountered malware-infected editions of the “Angry Birds Space” game which have been placed in unofficial Android app stores. The Trojan horse, which Sophos detects as Andr/KongFu-L, appears to be a fully-functional version of the popular smartphone game, but uses the GingerBreak exploit to gain root access to the device, and install malicious code. ...

The H-Online: A new version of NVIDIA’s proprietary UNIX graphics drivers for Linux, Solaris and FreeBSD fixes a security vulnerability (CVE-2012-0946) that allowed attackers to read and write arbitrary system memory in order to, for example, obtain root privileges. To take advantage of the vulnerability, an attacker must have access permission for some device files – which, for systems with these drivers, is typically the case for users who can launch a graphical interface as 3D acceleration and some other features cannot be used otherwise. ...

The H-Online: The Tuesday after the Easter weekend, 10 April, is set to be a busy one for system administrators as Microsoft and Adobe have sent out notifications that they will both be issuing fixes for critical vulnerabilities in their products. Microsoft’s April notification says there will be four critical advisories concerning Microsoft Windows, Internet Explorer, .NET Framework, Office, SQL Server, Microsoft Server and Developer tools, which all lead to remote code execution. A fifth remote code execution vulnerability in Office is marked as important, as is a sixth information disclosure issue in Microsoft’s Forefront United Access Gateway. The critical bulletins will affect all versions of Windows, from Windows XP SP3 to Windows Server 2008R2. One critical bulletin for Internet Explorer covers IE 6, 7, 8 and 9 ...

The H-Online: A Russian AV company, Dr. Web, says it has conducted research to determine the spread of the Flashback trojan on systems running Mac OS X and says that 550,000 systems are infected, mostly in the US and Canada. A later update raised that number to 600,000 and claimed 274 infected systems in Cupertino, California. Dr. Web says it employed a sinkhole technique to intercept the bot installed by the newest Flashback trojan, and directed the bots to its own servers where it could analyse the traffic. Each bot includes a unique ID of the machine it has infected in the query string it sends to the command and control server; it is these unique IDs that Dr. Web has used to calculate the infection count. According to its estimates, of the original 550,000 estimate, 56.6% of the systems were in the United States, 19.8% in Canada, 12.8% in the United Kingdom and 6.1% in Australia. ...

SophosLabs: Brian Krebs is reporting that MasterCard and Visa are warning member-banks of a payment processor breach that may impact more than 10,000,000 credit cards. It is important to note that MasterCard and Visa’s own networks were not involved in the attack, it appears to be related to payment processor Global Payments. Reuters is reporting that Global Payments stock was suspended for trading after falling more than 9% on the Nasdaq stock exchange. ...

The H-Security: Google has added new features to its OAuth 2.0 Playground, which it launched last November. Developers can now switch to using client-side flow, and the system has added support for APIs that use OAuth 2.0 drafts 10 to 25. Google has also added a feature that makes it easy to see all available API operations supported by the user’s current access token. To make it easier to use the Playground for an extended amount of time, developers now have the ability to refresh their access tokens automatically, and clicking HTTP response links will now populate the request URI field. ...

Cross posted from GFI, Sunbelt Blog: There’s not a day when we don’t see a new scam or hoax—yes, even the old ones—being proliferated on Facebook. I’ve seen both today. Let’s take a quick look at each one, shall we? First off, the scam: The screenshot above is a post generated by the “Sexappeal Meter” app that have spread within the social network. Clicking the “How much Sexappeal you have” link, or sometimes a bit.ly shortened URL, leads users to a page where it requests for permission just like any normal app. Allowing the app access to user profile, however, leads to two succeeding survey scam pages and, eventually, to a page where one can download a browser toolbar. ...
