Apple Mac OSX Zero-Day Bug Allows Hackers to Install RootKit Malware

Apple Mac OSX Zero-Day Bug Allows Hackers to Install RootKit Malware

Jun 02, 2015
A zero-day software vulnerability discovered deep in the firmware of many Apple computers could allows an attacker to modify the system's BIOS and install a rootkit , potentially gaining complete control of the victim's Mac. The critical vulnerability, discovered by well-known OS X security researcher Pedro Vilaca, affects Mac computers shipped before mid-2014 that are allowed to go into sleep mode. While studying Mac security, Vilaca found that it's possible to tamper with Apple computer's UEFI (unified extensible firmware interface) code. UEFI is a low-level firmware designed to improve upon computer's BIOS, which links a computer's hardware and operating system at startup and is typically not accessible to users. But… Vilaca found that the machine's UEFI code can be unlocked after a computer is put to sleep and then brought back up. " And you ask, what the hell does this mean? " Vilaca wrote in a blog post published Friday. " It means th...
Apple OS X Yosemite 10.10.2 Update to Patch years-old Thunderstrike vulnerability

Apple OS X Yosemite 10.10.2 Update to Patch years-old Thunderstrike vulnerability

Jan 27, 2015
Apple is preparing to release the second update to OS X Yosemite in the coming days to its customers. The upcoming beta update OS X Yosemite 10.10.2 contains a patch for the Thunderstrike vulnerability that allows malware to be injected into Macs via the Thunderbolt port. Earlier this month, Reverse engineer Trammell Hudson revealed technical details and proof-of-concept of Thunderstrike attack . Thunderstrike, an undetectable bootkit, works by injecting an Option ROM into a Mac's EFI. It is possible because hardware attached to a system through Thunderbolt port are not as secure as a Mac itself. Once installed using Thunderstrike attack, the malware would be almost impossible to detect and remove. Because the firmware used on Macs doesn't always apply to the security of attached hardware. So "Apple had to change the code to not only prevent the Mac's boot ROM from being replaced, but also to prevent it from being rolled back to a state where the at...
Thunderstrike — Infecting Apple MacBooks with EFI Bootkit via Thunderbolt Ports

Thunderstrike — Infecting Apple MacBooks with EFI Bootkit via Thunderbolt Ports

Jan 05, 2015
A security researcher has discovered an easy way to infect Apple's Macintosh computers with an unusual kind of malware using its own Thunderbolt port . The hack was presented by programming expert Trammell Hudson at the annual Chaos Computer Congress (30C3) in Hamburg Germany. He demonstrated that it is possible to rewrite the firmware of an Intel Thunderbolt Mac . The hack, dubbed Thunderstrike , actually takes advantage of a years-old vulnerability in the Thunderbolt Option ROM that was first disclosed in 2012 but is yet to be patched. Thunderstrike can infect the Apple Extensible Firmware Interface (EFI) by allocating a malicious code into the boot ROM of an Apple computer through infected Thunderbolt devices. The hack is really dangerous as, according to the researcher, there is no means for the user to detect the hack, or remove it even by re-installation of the complete OS X, only because the malicious code actually is in the system's own separate ROM.

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

Jun 26, 2025Data Protection / Compliance
SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...
