A new vulnerability in Sparkle has put a “huge” number of Mac applications at risk for hijacking. For those unfamiliar, Sparkle is a tool used often by third-party apps that are not in the App Store to allow updates to be pushed to users. Apps susceptible to this hijacking hack include Camtasia, uTorrent, DuetDisplay, and Sketch. The attack applies to both OS X Yosemite and El Capitan (via Ars Technica).

A serious vulnerability in Macs more than a year old would allow an attacker to take permanent control of the machine, retaining control even if the user reinstals OS X or reformats the drive.

The vulnerability was discovered by security researcher Pedro Vilaca, who found a way to reflash the BIOS – code stored in flash memory, not on the drive. This means that the machine remains compromised even if the hard drive is physically replaced …  expand full story

A former NSA staffer says that the OS X 10.10.3 update which Apple claims fixed a significant security vulnerability has failed to do so, reports Forbes. Patrick Wardle, who now heads up research at security firm Synack, demonstrated the vulnerability in a video (without revealing exactly how it was done) to allow Apple time to issue a further fix.

The Rootpipe vulnerability allows an attacker with local access to a Mac to escalate their privileges to root – allowing them full control of the machine – without further authentication. A second security researcher confirmed the flaw …  expand full story

The buggy code highlighted by arsTechnica

A bug in the way that 1,500 iOS apps establish secure connections to servers leaves them vulnerable to man-in-the-middle attacks, according to analytics company SourceDNA (via arsTechnica). The bug means anyone intercepting data from an iPhone or iPad could access logins and other sensitive information sent using the HTTPS protocol.

A man-in-the-middle attack allows a fake WiFi hotspot to intercept data from devices connecting to it. Usually, this wouldn’t work with secure connections, as the fake hotspot wouldn’t have the correct security certificate. However, the bug discovered by SourceDNA means that the vulnerable apps fail to check the certificate …  expand full story
