Chiffrement Jobs

A recently rebuilt Windows workstation needs a bullet-proof antivirus setup carried out over a remote session. The job begins with selecting an effective AV suite (I am open to your recommendation—Norton, McAfee, Kaspersky, or another best-in-class option) and continues through full installation, optimisation, and hardening. Key protection goals • Online banking: isolate browser sessions, enable real-time phishing & key-logger defences, and verify safe-transaction modules are active. • Confidential files: enforce on-access scanning, tune heuristic settings for maximum detection, and lock down local folders with password-protected vaults or encryption available within the AV. • Google Drive sync: ensure cloud-storage scanning is enabled, block malicious file ...

Project Overview This proof-of-concept will demonstrate a regulator-grade, fully secured VPC hosting a central authority and multiple financial-institution tenants, while automating supervision and compliance checks using native AWS services. Scope The environment will be logically segmented into public and private subnets for each participant. The central authority resides in its own network segment and can observe, query, and enforce policies across all other institutions without exposing sensitive resources publicly. Key Services AWS Lambda for event-driven oversight logic and scheduled compliance sweeps AWS RDS for the authoritative supervisory data store AWS S3 as the immutable audit and reporting repository Security & Compliance Networking, IAM, logging, encr...

I’m ready to commission the first release of a security-focused mobile application, launching on iOS before we expand to Android. The core of the product is continuous GPS tracking that must keep running in the background without draining the battery or being shut down by the OS. To protect sensitive medical data every byte stored on-device has to be encrypted and locked behind biometric authentication (Touch ID / Face ID) with an optional 4- to 8-digit passcode fallback. When pre-set conditions are met—location reached, time elapsed, or user action—the app should automatically issue push notifications to the user (and later to caregivers via a secure service we will integrate). Security is non-negotiable: please design with Secure Enclave, Keychain storage, SSL pin...

Loki Locker has locked the core system files on our main server. Every boot now triggers “Access denied” errors tied to the ransomware, and we can no longer load critical services or reach our data partitions. The immediate goal is to safely decrypt every affected system file without risking further corruption, confirm full file integrity, and then remove any remaining Loki Locker components so the machine can start cleanly again. A full post-recovery report outlining the exact steps taken and tools used will complete the engagement.

I am spinning up a fresh Windows Server 2022 instance on AWS EC2 and need it to behave exactly like our current Windows Server 2016 EC2 box. The goal is zero-difference for end-users once we switch over. Here is what must work out of the gate: • Classic ASP and IIS hosting for all of our existing sites, with bindings, SSL certificates, and application pools duplicated as they stand now. • Database services mirrored so every connection string continues to resolve without edits. • Third-party components already in use—including but not limited to: Auth0 for user authentication, the WodCrypt encryption library ( ), and ABCpdf from —installed, registered, and tested so the sites compile and run just as they do today. You will receive remote access to both the...

Looking for a Security Specialist to conduct a Grey-Box Penetration Test on a SaaS platform built with Laravel and React. The app helps real estate sourcers package deals using AI and third-party data. The objective of this project is to collate the results of a gray box test, identifying vulnerabilities and weaknesses at minimum in the application's authentication and authorization mechanisms, input validation, state management, access control and encryption of a web application. Testing will focus on identifying potential security risks and providing recommendations for remediation. Scope of Work: • Audit the Authentication/Authorization flow (JWT/Laravel Sanctum). • Test for IDOR and Broken Access Control between user accounts. • Audit API security (integrations ...

I’m building software for an industrial-grade Internet of Things device and need a developer who can take it from concept to a reliable, field-ready application. The work centers on firmware and companion software that can collect sensor data, push it to the cloud, and expose a clean API for downstream analytics or dashboards. Core needs • Firmware or embedded code that runs stably on the target hardware (ARM-based MCU) • Edge logic for data aggregation, local caching, and basic alert rules • Secure OTA update mechanism and device provisioning flow • Cloud integration (MQTT or REST) with authentication and encryption in place • A lightweight monitoring dashboard or reference client that demonstrates data ingestion and control commands I already ha...

I’m building a consumer-oriented Android app that can keep the camera rolling even after the user minimises it. A foreground service will handle uninterrupted video capture, then save each file locally and, when a network is available, sync it to an AWS S3 bucket. Core flow • First-time users sign in with phone-number verification (OTP). / Mail • Once authenticated, they can start and pause recording; the service must survive configuration changes, multitasking, and Doze mode. • Certain premium features unlock through an in-app purchase handled via Razorpay; a clean payment callback and refund flow are mandatory. What I need from you • Native Android code (Kotlin preferred) that cleanly implements CameraX/Camera2, foreground service, and WorkManager or ...
