Thunderstrike attack | Breaking Cybersecurity News | The Hacker News

If you think Apple's Mac computers are much more secure than Windows-powered systems, you need to think again. This isn't true, and security researchers have finally proved it. Two security researchers have developed a proof-of-concept computer worm for the first time that can spread automatically between MacBooks, without any need for them to be networked. Dubbed Thunderstrike 2 , the new proof-of-concept firmware attack is inspired by previously developed proof-of-concept firmware called Thunderstrike. Thunderstrike Attack , developed by security engineer Trammell Hudson, actually took advantage of a vulnerability in Thunderbolt Option ROM that could be used to infect Apple Extensible Firmware Interface (EFI) by allocating a malicious code into the boot ROM of an Apple computer through infected Thunderbolt devices. Thunderstrike 2 Spreads Remotely Although the original Thunderstrike required an attacker to have physical access to your Mac computer to wor...

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...

As SaaS providers race to integrate AI into their product offerings to stay competitive and relevant, a new challenge has emerged in the world of AI: shadow AI.  Shadow AI refers to the unauthorized use of AI tools and copilots at organizations. For example, a developer using ChatGPT to assist with writing code, a salesperson downloading an AI-powered meeting transcription tool, or a customer support person using Agentic AI to automate tasks – without going through the proper channels. When these tools are used without IT or the Security team's knowledge, they often lack sufficient security controls, putting company data at risk. Shadow AI Detection Challenges Because shadow AI tools often embed themselves in approved business applications via AI assistants, copilots, and agents they are even more tricky to discover than traditional shadow IT. While traditional shadow apps can be identified through network monitoring methodologies that scan for unauthorized connections based on...

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...

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.
