Device compromise assessment
We assess iPhones, iPads, and Android devices for signs of remote compromise including OS version exposure, forensic log indicators, and alignment with published exploit campaigns.
When your phone is hacked, your account is accessed without permission, or messages are sent that you did not authorise, you need confirmed answers - not guesses. SZ-SHIELD investigates what happened and documents it properly.
About
SZ-SHIELD is a global security firm headquartered in the United Kingdom, focused on digital forensics, compromise investigations, and mobile incident response. We work with clients worldwide who suspect their devices or accounts have been accessed without consent and need a clear, documented explanation of what occurred.
Modern attacks do not always look like traditional hacking. A victim may never download a suspicious app or enter a password on a phishing page. Instead, compromise can happen through a single visit to an infected website, a zero-day exploit chain targeting an outdated operating system, or a remote session that hijacks messaging functions without any visible interaction at the time of abuse.
Our role is to examine the device, the account activity, and the timeline surrounding the incident. We identify whether compromise occurred, how it happened, and whether subsequent activity is consistent with attacker control rather than user action.

Threat landscape
Attackers no longer need physical access to a phone or cooperation from the victim. Drive-by compromise through weaponized web pages can grant code execution, sandbox escape, and remote control of system functions including the Messages framework on iOS devices.
Once an attacker has control, they can send messages, access media, and log into linked accounts programmatically. From the recipient's perspective, the activity appears to come normally from the victim's phone number or account.
Every case follows the same structured path from first contact through to report delivery.
We capture the incident timeline, device details, account activity, and corroborating evidence.
We examine device logs, OS exposure, login records, and messaging metadata.
We verify security updates and confirm known vulnerabilities have been patched.
We deliver a formal report and continue monitoring the device where required.
Global
SZ-SHIELD is headquartered in the UK and serves clients across Europe, the Americas, the Middle East, and Asia-Pacific through remote forensic review and structured incident reporting.
Mobile exploit kits and account-based attacks do not respect borders. We deliver the same disciplined forensic approach regardless of where the client is based.
Why SZ-SHIELD
Case types
Compromise cases rarely arrive with a clear label. Victims often discover something is wrong only when a contact reports a strange message or a login notification appears from an unknown location.
Messages sent from your account while you were unable to use the device.
Sessions that do not match your location or known devices.
Damaging content sent to contacts as a deliberate reputational attack.
Confirmation that patches closed the exploit path plus ongoing monitoring.
FAQ
Yes. If your device is compromised through a mobile exploit chain, an attacker can invoke messaging functions without requiring you to unlock the phone, open the app, or tap send. This is a documented capability of full-chain iOS and Android exploits.
Indicators include unauthorized account logins, messages you did not send, activity while you were elsewhere, and running an outdated OS version targeted by active exploit kits. A forensic assessment confirms whether compromise occurred.
Devices on older, unpatched OS branches are actively targeted because known vulnerabilities can be exploited at scale. The OS version and patch status matter more than hardware age alone.
Device profile, incident timeline, technical analysis, findings on unauthorized activity, remediation status, conclusions, and analyst certification. Structured for legal or personal records.
Yes. SZ-SHIELD is headquartered in the UK but operates globally. We handle remote forensic review and formal reporting for clients in any country.
