Generally display under the Power Control area.

In both APM and ACPI computers, settings for Wake-on-LAN (WOL):.

You need to configure specific BIOS settings to enable remote wake-up on your system. Network management programs typically send wake-up packets, though you can use simple programs for this purpose (available on the Internet at no charge). The memory contents swap to the disk drive, and then reload into RAM when the system wakes.ĪCPI-aware operating systems support remote wake-up from standby or hibernate mode.

S4 - Suspend to disk (hibernate mode).

The CPU clock stops, but RAM powers on and refreshes.

S1 - System is in low-power mode (sleep mode).

Each state represents a different level of power, from fully powered up to completely powered down, with partial levels of power in each intermediate state. Newer computers feature Advanced Configuration and Power Interface (ACPI), which extends the APM concept to allow the OS to selectively control power by individual components.ĪCPI supports many power states. This early implementation didn't require an OS that was aware of remote wake-up.ĪPM provided BIOS-based power control. The ability to power on the computer allowed network administrators to complete off-hours maintenance at remote locations without sending a technician. The power control circuitry, in response, activates power resulting in the computer starting the OS.

The system could start from a powered off state by sending a Magic Packet*. By toggling a signal connected to the computer power control circuitry, the adapter responds to a Magic Packet that has its own MAC address. The feature has evolved from a simple remote power-on to a complex system able to interact with many devices and operating system (OS) power states.Įarly implementations required the system to have a standby power supply. For now these vulnerabilities are being used only (as far as we know) to jailbreak iPhones, but they could be used to do many other things to iPhones and their owners around the world.The ability to remotely wake computers is an important development in computer management. This should serve as a wake-up call for anyone with a mobile device: Remote exploitation is real and here to stay. Read this article in The Register for a real nice breakdown of it. It originally targeted power-plant control systems as the Stuxnet worm and then appeared in more mainstream malware because it was an unpatched vulnerability with working exploit code. LNK vulnerability that Microsoft fixed yesterday via an out-of-band patch.

I hope I am not the only one who is bothered by this because it begs the question “What else can this be used for?” Vulnerabilities with reliable exploit code tend to get reused and repurposed for other attacks/malware/uses. (I have not seen confirmation from Apple that these are in fact zero-day vulnerabilities, so keep that in mind). We call code that takes advantage of zero-day vulnerabilities zero-day exploits.

VUPEN Security is not aware of any vendor-supplied patch.ĭid you notice the line “VUPEN is not aware of any vendor-supplied patch”? In the security business we call those zero-day vulnerabilities. Note: These flaws are currently being exploited by jailbreakme to remotely jailbreak Apple devices. The second vulnerability is caused by an error in the kernel, which could allow attackers to gain elevated privileges and bypass sandbox restrictions.

The first issue is caused by a memory corruption error when processing Compact Font Format (CFF) data within a PDF document, which could be exploited by attackers to execute arbitrary code by tricking a user into visiting a specially crafted web page using Mobile Safari. Two vulnerabilities have been identified in Apple iOS for iPhone, iPad and iPod, which could be exploited by remote attackers to take complete control of a vulnerable device. (I believe the first tweets I saw were from Brian Krebs.) I then saw posts from VUPEN that several flaws were being exploited. While still at Defcon, I saw through Twitter that one exploit or another was being used to remotely jailbreak the iPhone. Like many iPhone users, I was also very happy to learn that Dev-Team would soon make remote jailbreaking possible by simply visiting their jailbreakme website. Like many iPhone users, I was quite happy when the Electronic Frontier Foundation (EFF) was able to get jailbreaking included under “fair use” within the Digital Millennium Copyright Act. I do this for many reasons, but mainly for console-level access and the darn cool infosec tools that are available through Cydia. Like many iPhone users, I “jailbreak” my iPhone.
