Apple has released four new iPad Pro commercials that tell us why the device is better than traditional computer or laptop for most people. All ads are available below as well as on Apple’s official YouTube channel.
The first video tells us that there are no viruses on the iPad Pro, which makes this device better than a computer.
A new piece of malicious software for Mac computers called Xagent has been recently found by the Bitdefender security experts. It is a modular backdoor that penetrates into the system and can steal browser passwords, take desktop screenshots, and even steal iPhone backups stored on the computer. The malware was reportedly created by a group of hackers called APT28.
As noted by independent Mac security researchers, there are two new instances of malware for macOS. The first piece of malicious software uses Microsoft Word to penetrate into the system and the second one pretends to be a software update and then hacks the system.
As it was reported yesterday, a new ransomware virus has recently infected Mac computers. In case you missed our previous article, it was spread through the program called Transmission. Those who downloaded the infected installer, ended up having a virus blocking access to the sensitive data on their machines.
Last weekend, many Mac computers across the globe were infected by new ransomware. It’s called “KeRanger” and it was spread alongside with a program called Transmission. This malware was spread through the BitTorrent peer-to-peer file sharing network.
A new OS X bug has been recently discovered by German security researchers. This software flaw allows spammers and hackers get access to IP addresses and other sensitive information through the Spotlight search feature of OS X.
Karsten Nohl claims that some SIM cards feature a flaw in the encryption technology, so that telephones with the cards can be spied on.
This flaw enables the hackers to send a spoof text message to the device. The latter will answer by revealing the 56-bit data encryption standard key (DES). Using the key, the attacker gains possibility to install dangerous software on the device and even listen in on your phone calls, access/send text messages and much more.
Those who want to save their privacy should buy Android, not Apple devices. A kind of bold statement, isn’t it? According to the latest BitDefender report, iOS platform is more dangerous in terms of personal data protection, than the Google’s mobile operating system.

Researchers announced on this Monday that they had discovered vulnerability in Java 7. Hackers can use the bug to compromise any system through a web browser running the latest Java software, reports Tod Beardsley, engineering manager for open-source testing framework.
Russian antivirus company Dr. Web issued a report on Wednesday noting that hundreds of thousands of Macs are infected with the Flashback Trojan, with more than half of them in the U.S. alone. The attack takes advantage of an old Java vulnerability that Apple just patched this week. The malware self-installs after you visit a compromised or malicious webpage.
Security lab F-Secure released its 2011 Mac Malware Summary earlier this week, noting that Mac OS X platform endured 58 separate malware attacks from April 2011 to December 2011. Of course, this numbers couldn’t be compared with multiply attacks that Microsoft's Windows operating system experienced over the same period.
The firm counted only unique variants of malware that occurred during the second, third and fourth quarters of 2011. "We prefer a more conservative approach when counting malware. The more generic and family based, the better," the report noted.
A security firm Sophos, released a report which claims that a new Trojan horse was found to be hidden in a Mac OS X application, Graphic Converter 7.4.
The new Trojan called DevilRobber can steal sensitive user data, usernames and passwords, and take control of the computer’s GPU to generate Bitcoins, a form of currency used online, and is capable of spying on users by taking screenshots of their activity and sending the images online. DevilRobber, also known as "OSX/Miner-D," also runs scripts that can copy information “regarding truecrypt data, Vidalia (TOR plugin for Firefox), your Safari browsing history, and .bash_history” to a dump.txt file. The malware is also able to search for “pthc” files (the term means pre-teen hardcore pornography). And probably that is one of its secondary features to find traces of child abuse on affected computers that could be used against owners of such computers, for example.
Sophos suggests that users may notice that their computers have been attacked by the Trojan. This may affect overall computing performance when the Trojan steals GPU resources. The company asks users not to download software from unreliable sources. Though, common anti-virus programs are able to detect the Trojan.
Apple has released a software update that is able to automatically find and remove known variants of the MacDefender malware. The company added a “OSX.MacDefender.A” definition to the malware check and while installation the malware should be find and removed, then users should be notified that the MacDefender is removed.
Apple maintains a list of known malicious software that is used during the safe download check to determine if a file contains malicious software. The list is stored locally, and with Security Update 2011-003 is updated daily by a background process.
