Device compromise investigations and digital forensics you can act on

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.

What we investigate

  • 01 Remote device compromise via mobile exploit chains
  • 02 Unauthorized Apple ID, Google, and email account logins
  • 03 Messages and media sent from compromised devices
  • 04 Drive-by web attacks targeting iOS and Android browsers
  • 05 Post-incident monitoring and remediation verification

About

Built for real compromise cases

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.

Services

Investigation and response capabilities

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.

Digital forensics

We reconstruct the sequence of events around an incident by analysing login records, messaging activity, app foreground events, and network indicators.

Mobile incident response

We guide emergency remediation, verify security updates, confirm the exploitation path is closed, and continue surveillance on affected devices.

Account activity review

We correlate Apple ID, iCloud, Google, and email login timestamps against known user activity to identify sessions the account holder did not initiate.

Forensic reporting

Structured incident reports for personal records, legal counsel, insurers, and corporate review including timelines, technical analysis, and analyst certification.

Threat intelligence alignment

Analysis grounded in published research on active mobile exploit kits, zero-day disclosures, and vendor security advisories.

Threat landscape

Why device compromise is harder to detect than it used to be

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.

Common indicators we examine

  • - Outbound messages sent while the subject was elsewhere or in a meeting
  • - Apple ID or cloud logins with no corresponding user activity
  • - Device on a vulnerable OS branch without current patches
  • - No Messages app foreground event when a message was sent
  • - Content sent that the subject denies and that fits harassment patterns

How an investigation works

Every case follows the same structured path from first contact through to report delivery.

1

Intake and triage

We capture the incident timeline, device details, account activity, and corroborating evidence.

2

Forensic analysis

We examine device logs, OS exposure, login records, and messaging metadata.

3

Remediation review

We verify security updates and confirm known vulnerabilities have been patched.

4

Report and monitoring

We deliver a formal report and continue monitoring the device where required.

Who we work with

  • + Individuals who believe their device or accounts have been compromised
  • + Legal professionals requiring documented forensic findings
  • + Corporate teams responding to targeted mobile attacks on executives
  • + Advisors supporting victims of harassment via compromised accounts

Global

Based in the UK, operating worldwide

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

Investigations grounded in evidence

Confirmed

Definitive findings

We state what the evidence shows. If a device was compromised, we say so clearly and explain the mechanism.

Timeline

Event reconstruction

Incident timelines cross-reference device activity, account logins, and independent corroboration.

Confidential

Discreet handling

All engagements are confidential. Reports go only to authorized recipients.

Case types

Incidents we handle worldwide

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.

Unauthorized outbound messaging

Messages sent from your account while you were unable to use the device.

Suspicious account logins

Sessions that do not match your location or known devices.

Post-exploit harassment

Damaging content sent to contacts as a deliberate reputational attack.

Remediation verification

Confirmation that patches closed the exploit path plus ongoing monitoring.

FAQ

Common questions

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.
