![]() ![]() Web's checker to determine if your system may be compromised. So far, a number of tools have been released by some reputable security firms that will detect and remove this threat from OS X systems. The first of these tools is F-Secure's Flashback remover, which will extract known variants of the malware from its location within applications and user accounts, and save them in a benign zip file, which can then be destroyed or sent in for analysis. The second such tool is from Kaspersky labs and is called the Flashfake removal tool. This tool runs a number of Unix commands within an AppleScript that will remove any known malware and notify you of the results. Unlike F-Secure's option, it will just remove the malware and not quarantine it. Symantec was the third to release its Flashback removal option, which it has supplied as a shell script and Ruby script combination. Unlike those from Kaspersky and F-Secure, Symantec's solution runs within the OS X terminal but launches by double-clicking the script file located within the downloaded disk image.Īpple followed an announcement of its own Flashback removal tool (available via Software Update) with the release of one that accompanies yet another update to the Java runtime for both OS X 10.6 and 10.7. This tool is reminiscent of the tool Apple released to remove the MacDefender malware, and is a native Cocoa application instead of being a script-based tool as is the case with other options. The program will run when the Java update is applied, and will remove the malware and upload the results to Apple's servers, followed by deleting itself from the system.Īpple today released a separate stand-alone version of its MRT utility however, it is only for OS X Lion users who do not have Java installed on their systems. FLASHBACK MALWARE REMOVAL TOOL 10.6.8 UPDATE This appears to be an effort to help detect earlier variants of the malware that these users might have encountered. So far there is no such option from Apple for other versions of its Mac operating system. ![]() Note that these tools are not full antivirus scanners, and instead are simple run-once scripts programs that are intended to quickly clear the problem instead of providing ongoing protection.

At the time of writing the Cupertino-based company was yet to release the malware removal tool. ![]() "Too many users are unaware that their computers have been infected, or that there is a real threat to Mac security," said Gostev.Īpple said that while the vulnerability had been patched, it is still "developing software that will detect and remove the Flashback malware". He added that the problem was exacerbated by the "myth" of Apple computers being "malware free". "Apple knew about this Java vulnerability for three months, and yet neglected to push through an update in all that time." "The three-month delay in sending a security update was a bad decision on Apple's part," said Gostev. This meant Mac users were left exposed to the infection for much longer than users of other operating systems. While Oracle, which develops Java, issued a patch for Windows and Linux machines around three months ago, Apple patches the Java implementation on OS X itself and only issued a fix earlier this month. Of those, around 47,000 are based in the UK. Kaspersky said around 98 per cent of the 600,000 machines infected with the Flashback malware run OS X. The infection makes it one of the largest in Apple's history. ![]()
