New Variant Of Flashback For Mac Attacks Again [Updates]

 

Flashback, the Mac OS X trojan we began reporting on months ago, just won’t go away in spite of numerous Apple updates designed to patch the Javascript security hole that Flashback was jumping through.

The latest version, discovered on Monday by the Intego, has been labeled Flashback.S. It spreads using the same vulnerability as earlier versions, which means that it requires no password prompt to install itself on a targeted system.

There’s a new trick, too – this variant will delete files in ~/Library/Caches/Java/cache to remove traces of the trojan and prevent the recovery of samples by security firms (a ruse that,
obviously, hasn’t worked).

If you haven’t already updated your Mac (shame on you!), do so now. Apple’s updates to patch the flaw used by Flashback will work against this and all other know versions. The patch can be downloaded using the update service built in to OS X.

You can also protect yourself by installing an antivirus. According to Intego, Flashback does not even attempt to install itself on systems protected by certain software. This has been true since the original version and is likely an attempt to slow the detection of new variants.

Apple Launches Web Tool to Deregister Phone Numbers from iMessage

Apple today released a new web tool for users to deregister their phone number from iMessage in the event they switched to a non-Apple device. To deregister a phone number from iMessage, users simply enter their phone number in Apple's web tool, receive a free text message containing a code, and submit the code to complete the process. Users who still have their original iPhone can also transfer their SIM card back to the device and go to Settings -> Messages to turn iMessage off. 


Users switching from an iPhone to another device were often unable to receive SMS messages from another iPhone due to their phone number still being linked to iMessage. These specific errors with iMessage have been a well-known issue since 2011, which is when the messaging service debuted with iOS 5. They were also made even more apparent this past May, where a server glitch caused widespread message delivery problems. Apple was even sued over the matter in a California court, although the company cla…

Microsoft acquires iPhone email app Acompli

After accidentally announcing it a little early, Microsoft is officially confirming it has acquired email startup Acompli. The surprise acquisition means Microsoft is picking up a powerful email client for iPhone and Android in another move that further cements CEO Satya Nadella’s focus on cross-platform technologies. The Verge’s Casey Newton called Acompl "the Outlook for iPhone that Microsoft hasn’t yet built," and it seems Microsoft was equally impressed with the powerhouse email app. "We’re excited about what’s possible as we build on the app’s success and bring it together with work currently in progress by the Outlook team," the company said in a statement. "Our goal is to deliver fantastic cross-platform apps that support the variety of email services people use today and help them accomplish more." Recode first reportedthat Microsoft would make its latest acquisition official today; the company is said to be paying over $200 million for Acompli.

Apple will disconnect ‘obsolete’ first-gen Apple TV from iTunes in May

Apple has announced today it will drop iTunes support for some older devices from May 25. This includes the first generation Apple TV, and also any PC running Windows XP or Vista. The company is introducing new security changes which will prevent those devices from using the latest version of iTunes.
Apple says that the original Apple TV is an "obsolete Apple product" and will not be updated to support security changes. Only those with the second generation of Apple TV or later will be able to access the iTunes store.
Windows XP or Vista users won't be able to use the latest version of iTunes, but older Windows computers can still use previous versions without support from Apple. Those who do so, however, won't be able to make new purchases or re-download previous purchases on that computer. If you're on on XP or Vista, you'll need to upgrade to Windows 7 or later to continue using iTunes normally.
The writing was already on the wall for these devices: Wi…
