Stock, non-jailbroken iOS devices appear to be vulnerable to a new security threat; a trojan known as AceDeceiver, which can be installed on an iOS device without the user’s knowledge and without the help of an enterprise certificate. Once installed, it will spread malware and unwanted software to the user’s device.
AceDeceiver only seems to be affecting those located in China at this point in time, but because that could change on the fly, you need to know how to protect yourself so similar threats don’t affect users across the globe in the future.
Sometimes, you get an email that you think is legit, and it turns out it’s just a fake email pretending to be something it’s not. In this piece, we’ll go over some of the things you can look for to tell if the emails you’re getting are legitimate, or if they’re a potential scam or security risk.
Users of the popular open-source Transmission BitTorrent client for OS X were in for quite a surprise this weekend when it was discovered that certain installers for version 2.90 of the application were found to bundle unwanted ransomware with the installation, which is a type of malware that restricts file access across the system to cause trouble for the user.
Dubbed KeRanger by security research firm Palo Alto Networks, the malicious software will try to encrypt the user’s system files in such a way as to tamper with the user’s access to their Mac and then force the user to pay money to get their access back.
The makers of the Transmission app are now pushing immediate mandatory app updates to remove the ransomware and fix the problem for those that may have been affected, and it’s recommended for all users, but how do you know if you’re affected?
All Macs with OS X El Capitan installed on them have a new layer of security known as System Integrity Protection, which has been given the nickname ‘Rootless’ because it closes off a lot of system files to user access to prevent malicious programs and code from causing harmful changes to the core of OS X.
For some, the added security feels like a must for protection of your personal information, but for more advanced users who poke their noses into system files quite often, the feature can get in the way and prevent user modifications to the operating system. In this tutorial, we’ll give you an overview of System Integrity Protection and show you a way to disable it.
Apple today refreshed its official XcodeGhost FAQ webpage, listing the top 25 iPhone and iPad apps on the App Store that contain the widely reported though mostly harmless XcodeGhost malware.
In addition to WeChat, one of the top messaging apps in the world, Rovio’s Angry Birds 2 and China Unicom’s Customer Service app, most of the listed apps are distributed on the Chinese App Store only.
“If users have one of these apps, they should update the affected app which will fix the issue on the user’s device,” writes the company. “If the app is available on App Store, it has been updated, if it isn’t available it should be updated very soon.”
Apple has pulled many of the infected apps and said it’s working closely with developers to get impacted apps back on the App Store.
The XcodeGhost malware couldn’t have arrived at worst time for Apple as the company prepares to launch its iPhone 6s and iPhone 6s Plus tomorrow. The company has already removed the App Store apps infected by the malware, which has been found to inject its payload into apps compiled with compromised copies of Xcode that were distributed on non-Apple servers in China.
Wednesday, the Cupertino firm has confirmed plans to mitigate the threat by hosting local Xcode downloads within China. In addition, Apple has posted an XcodeGhost FAQ webpage on its Chinese website detailing the XcodeGhost malware and how customers might be affected by it.
A new type of attack called XcodeGhost is wreaking something of a mini-havoc in the App Store, injecting its malware payload into popular iPhone and iPad apps and prompting Apple to pull the infected apps.
The malware itself is pretty harmful—it collects and sends information about your device—but the method of spreading is cunning. Rather than target the App Store itself, attackers have distributed hacked versions of Xcode, Apple’s tool required for iOS and OS X development.
As Xcode is a multi-gigabyte download, developers in countries like China where Internet speeds are slow have downloaded these modified Xcode builds from non-Apple sources without realizing a hacked Xcode injects malware when compiling apps.
This morning, Apple issued an email to developers providing an update on the XcodeGhost situation while laying out easy-to-follow instructions for checking if their Xcode copy has been tampered with.
A few dozen iPhone and iPad applications, most of them developed for China, have been infected with XcodeGhost, a malware that collects information on the devices and uploads that data to remote servers.
Among them is WeChat, one of the most popular instant messaging applications in the world.
Rather than exploit an iOS vulnerability, the malware in question sneaks its way into apps indirectly, by targeting Apple’s official compilers used to create legitimate apps. The malware was found to inject its malicious code into a Mach-O object file that was repackaged into some versions of Xcode, Apple’s official tool for developing iOS and OS X apps.
These Trojanized Xcode installers were then uploaded to Baidu’s cloud file sharing service used by Chinese app developers, explains Palo Alto Networks. The malicious code then inserts itself into any iOS app compiled with the infected Xcode without the developers’ knowledge.
It’s not Apple’s fault, really: this would have never happened had these developers downloaded Xcode files directly from Apple. Baidu has since removed all of the infected files from its servers and some of the infected apps have since removed the malware code in their latest builds.
Apple has decided to eliminate the category of anti-virus and anti-malware products from the App Store, according to security firm Intego. The company announced this week that Apple informed them of their decision after pulling their app ‘VirusBarrier for iOS.’
“To be clear, this wasn’t an action directed specifically at Intego, we were one of several companies affected by Apple’s decision,” writes Intego’s Jeff Erwin. Erwin adds that users will continue to get virus definition updates, but there will be no more updates to the app.
Chinese authorities arrested three individuals last Friday that are believed to have developed the “WireLurker” malware, according to a police post on Sina Weibo. The authorities were tipped off by Chinese security company Qihoo 360 technology. Additionally, the post says that authorities have also identified and shut down the website that was hosting and distributing the malware.
