Hackers are testing new Mac malware that they've ported from a nine-year-old Trojan horse originally written for Linux, according to security experts.
The malware, dubbed "Tsunami," has been circulating in limited numbers since last week, said researchers at the Slovakian antivirus firm, ESET Security.
A new Trojan horse hidden in a Mac OS X application can steal sensitive user data and take control of the computer’s GPU to generate Bitcoins, a form of currency used online.
In a report released on Saturday, security firm Sophos said that DevilRobber, a Trojan horse that can steal sensitive user data, was found hidden inside copies of Graphic Converter 7.4 downloaded from bit-torrent file-sharing sites.
OSX/Tsunami-A, a new backdoor Trojan horse for Mac OS X, has been discovered.
What makes Tsunami particularly interesting is that it appears to be a port of Troj/Kaiten, a Linux backdoor Trojan horse that once it has embedded itself on a computer system listens to an IRC channel for further instructions.
If you have enabled iCloud's Find My Mac feature in OS X Lion, then you will notice that the OS X log-in screen now shows a Guest user account, which when clicked will offer the option for rebooting the system into Safari-only mode.
This mode will run the system in a limited environment where it can be used for Web surfing, but not much else. The system will only allow Safari to run in plain vanilla form without any plugins (including Flash) or extras running, and if you quit the browser then the system will restart back to the log-in screen.
Apple on Wednesday issued much-anticipated updates for its Mac OS X and iOS mobile operating system, adding support for its new iCloud service and fixing a bevy of security flaws in the process.
The new mobile operating system, iOS 5, contains approximately 98 security fixes, according to the company's release notes. The iOS update addresses a number of “noteworthy” issues, including flaws that caused users' Apple ID passwords to be logged in a plain text file, readable by applications, Graham Cluley, senior technology consultant at Sophos, said in a blog post Wednesday.
Chinese malware targeting Mac users wasn't actually functional, but Apple has squashed the exploit anyway by delivering a malware definition update that flags the Trojan Horse as being malicious when users try to open it.
New malicious software reported by CNET this week has been added to Mac OS X's internal blacklist of known malware, erasing the threat even before its authors were able to get it to the point of actually functioning.
An Australian security expert respected for his work testing the defences of Apple software has published a method which appears to allow an attacker to break through the password defences of Cupertino’s latest Max OS X Lion operating system.
Multiple security companies are warning that they have received samples of a new Mac Trojan. It seems that the Trojan has yet to be seen in the wild.
Dubbed Revir.A, the Trojan poses as a PDF file. Masking an executable as a document is a well-known trick.
Do you happen to be one of those people that really love Mac OS X Lion? Or perhaps, on the other end of the spectrum, you feel Lion's a bit too much like iOS? Well, now it's more than just similar, because if you happen to have an iPhone or iPod Touch, you can now make sure that Lion never leaves your side, with a bit of clever hacking.
The latest version of OS X Lion allows any user to easily change the password of any local account, due to permissions oversights on Apple's part. The news comes less than a month after another Lion vulnerability that let users bypass LDAP without a password gained notoriety.
