MITRE ATT&CK

Techniques & procedures

6 distinct techniques documented for this family, organized by ATT&CK tactic.

Initial Access

1 technique

T1200Hardware AdditionsEvidence1

Exploiting the vulnerability requires physical access to the device: the device must be plugged in to a computer upon booting, and it must be put into Device Firmware Update (DFU) mode.

Execution

1 technique

T1203Exploitation for Client ExecutionEvidence1

Some Apple devices are vulnerable to arbitrary code execution at the Boot ROM level (called "SecureROM" by Apple) by exploiting a use-after-free vulnerability. Successful exploitation results in the ability to execute arbitrary code on the device. checkm8 is a public exploit for this vulnerability.

Persistence

2 techniques

T1542Pre-OS BootEvidence1

The attacker can load unsigned firmware or lower the device’s security level.

T1542.003BootkitEvidence1

Individuals who operate under elevated threat conditions... face a significantly different risk profile. In such scenarios, a compromised device based on A12, A13, S4, or S5 could be affected by persistent boot-level intrusions that are anchored underneath the operating system itself, even after software updates are applied.

Privilege Escalation

1 technique

T1068Exploitation for Privilege EscalationEvidence5

Exploitation for Privilege Escalation (T1068) - повышение привилегий до уровня ядра; checkm8 даёт это на A5–A11, для A12+ нужны 0-day цепочки

Stealth

2 techniques

T1542Pre-OS BootEvidence1

The attacker can load unsigned firmware or lower the device’s security level.

T1542.003BootkitEvidence1

Credential Access

1 technique

T1212Exploitation for Credential AccessEvidence1

Mobile extraction tools like Cellebrite and MSAB’s can break into locked iPhones but the success rate depends on a combination of model, operating system, underlying chipset, etc. Most of them use known exploits. For instance, the latest versions of UFED and XRY rely on the checkm8 exploit to extract data from iPhones.
