Κυκλοφόρησε το πρώτο Κακόβουλο Λογισμικό για τα νέα Macs με επεξεργαστή Μ1!



Macs with Apple's M1 processor have only been around for a few months, but it didn't take long for hackers to start targeting the systems. Security researcher Patrick Wardle says he has found a malicious app that was created specifically for the powerful M1 chip.

He
wrote in a blog post that the Safari adware extension, which is called GoSearch22, was originally designed for Intel x86 processors. It appears to be a variant of the well-known Mac adware Pirrit. Wardle told Motherboard that the malware seems "fairly vanilla" — it collects user data and peppers the screen with illicit ads — but noted that its developers could update GoSearch22 with more harmful functions.

Although new Macs can still run apps designed for Intel x86 chips via emulation, many developers are creating native
M1 versions of their software. The existence of GoSearch22, Wardle wrote, "confirms malware/adware authors are indeed working to ensure their malicious creations are natively compatible with Apple’s latest hardware."

Wardle discovered the malware on
Alphabet-owned antivirus testing platform VirusTotal, where someone uploaded it in December. The researcher found that, although the platform's antivirus scanners flagged the x86 version of the adware as malicious, 15 percent of them didn't suspect the M1 version of GoSearch22 was malware. That suggests not all antivirus software is fully ready to root out malware designed for M1-based systems. Another researcher, Thomas Reed, told Wired that compiling software for "M1 can be as easy as flicking a switch in the project settings," so it seems hackers might not have to do much to adapt their malware for Apple's latest processor.

GoSearch22 was signed with an Apple developer ID in November, according to Wardle. However, Apple has revoked the adware's certificate, which will make it difficult for users to install it.

Major Thunderbolt security flaws found, affect Macs shipped in 2011-2020!



No fewer than seven serious Thunderbolt security flaws have been discovered, affecting machines with both standalone Thunderbolt ports and the Thunderbolt-compatible USB-C ports used on modern Macs.

The flaws allow an attacker to access data even when the machine is locked, and even when the drive is encrypted …

The vulnerabilities are present in all machines with Thunderbolt/Thunderbolt-compatible USB-C ports shipped between 2011 and 2020.

Security researcher Björn Ruytenberg found seven vulnerabilities in Intel’s Thunderbolt chips, and nine ways to exploit them.

1. Inadequate firmware verification schemes

2. Weak device authentication scheme

3. Use of unauthenticated device metadata

4. Downgrade attack using backwards compatibility

5. Use of unauthenticated controller configurations

6. SPI flash interface deficiencies

7. No Thunderbolt security on Boot Camp

There is no way to detect that a machine has been compromised.

Thunderspy is stealth, meaning that you cannot find any traces of the attack. It does not require your involvement, i.e., there is no phishing link or malicious piece of hardware that the attacker tricks you into using. Thunderspy works even if you follow best security practices by locking or suspending your computer when leaving briefly, and if your system administrator has set up the device with Secure Boot, strong BIOS and operating system account passwords, and enabled full disk encryption. All the attacker needs is 5 minutes alone with the computer, a screwdriver, and some easily portable hardware.

These vulnerabilities lead to nine practical exploitation scenarios. In an evil maid threat model and varying Security Levels, we demonstrate the ability to create arbitrary Thunderbolt device identities, clone user-authorized Thunderbolt devices, and finally obtain PCIe connectivity to perform DMA attacks. In addition, we show unauthenticated overriding of Security Level configurations, including the ability to disable Thunderbolt security entirely, and restoring Thunderbolt connectivity if the system is restricted to exclusively passing through USB and/or DisplayPort. We conclude with demonstrating the ability to permanently disable Thunderbolt security and block all future firmware updates.

Macs are fully vulnerable to all of the Thunderbolt security flaws when running Bootcamp, and ‘partly affected’ when running macOS.

MacOS employs (i) an Apple-curated whitelist in place of Security Levels, and (ii) IOMMU virtualization when hardware and driver support is available. Vulnerabilities 2–3 enable bypassing the first protection measure, and fully compromising authenticity of Thunderbolt device metadata in MacOS “System Information”. However, the second protection measure remains functioning and hence prevents any further impact on victim system security via DMA. The system becomes vulnerable to attacks similar to BadUSB. Therefore, MacOS is partially affected.

Further details of the Mac vulnerabilities can be found below.

Ruytenberg informed both Intel and Apple of his discoveries, but says that as the Thunderbolt security flaws are present in the controller chips, there is no way to fix the vulnerabilities via a software update.

Below is a description of how the vulnerabilities can be exploited on a Mac running macOS. This is essentially performed by fooling the Mac into thinking the attack kit is an Apple-approved Thunderbolt accessory.



3.4 Exploitation scenarios for vulnerabilities 2-3, 7 on Apple Mac systems

3.4.1 Cloning an Apple-whitelisted device identity to an attacker device (MacOS) 4

Threat model

We assume an “evil maid” threat model, in which the attacker exclusively has physical access to a victim system. The system is in a locked (S0) or sleep (S3) state, while running MacOS.

Preparation

1. Acquire a MacOS-certified Thunderbolt device.

2. Disassemble the MacOS-certified device enclosure. Obtain the firmware image from the Thunderbolt controller’s SPI flash of the MacOS-certified device.

3. Disassemble the attacker device enclosure. Obtain the firmware image from the Thunderbolt controller’s SPI flash of the attacker device.

4. Connect the MacOS-certified device to the attacker system. On the attacker system, using e.g. tbtadm on Linux, obtain the UUID of the MacOS-certified device.

5. Locate the DROM section by searching for the string DROM in the attacker device firmware image. Figure 6 depicts the DROM data structure. Using the figure as a reference, locate the appropriate offsets and replicate the MacOS-certified device UUID.

6. Compute uid crc8 and replicate the value at the appropriate offset.

7. Write the image to the attacker device SPI flash.

Procedure

1. Connect the attacker device to the victim system.

Verification

1. Observe that the victim system identifies the attacker device as being a MacOS-certified device. Figure 2 demonstrates an example scenario, showing a forged Thunderbolt device identity in the MacOS “System Information” application.



Intel commented:

In 2019, major operating systems implemented Kernel Direct Memory Access (DMA) protection to mitigate against attacks such as these. This includes Windows (Windows 10 1803 RS4 and later), Linux (kernel 5.x and later), and MacOS (MacOS 10.12.4 and later). The researchers did not demonstrate successful DMA attacks against systems with these mitigations enabled. Please check with your system manufacturer to determine if your system has these mitigations incorporated. For all systems, we recommend following standard security practices, including the use of only trusted peripherals and preventing unauthorized physical access to computers.

MacPro με κόκκινο χρώμα και νέο σχεδιασμό!




Γνωρίζουμε, εδώ και καιρό, ότι ο αρχισχεδιαστής της Apple, Jony Ive, συνεργάζεται με το φίλο του και σημαντικό designer Marc Newson, "αναμορφώνοντας" ή σχεδιάζοντας από την αρχή διάφορα αντικείμενα για φιλανθρωπικούς σκοπούς.

Σ' αυτό το πλαίσιο, ο νέος ιδιαίτερος σχεδιαστικά Mac Pro της εταιρείας γίνεται RED, σε μία αποκλειστική έκδοση που θα δημοπρατηθεί από τον οίκο Sotheby, με στόχο να συγκεντρωθούν από 40.000 έως 60.000 δολάρια για φιλανθρωπικά σωματεία.

Αν μη τι άλλο, μία μοναδική πρόταση στο στιλ των υπόλοιπων "RED" προϊόντων που έχει λανσάρει κατά καιρούς η Apple και η οποία αναμένεται να δημοπρατηθεί στις 23 Νοεμβρίου.
