    My dedicated Linux server suddenly jumped to 100 % CPU, cPanel accounts refuse to load, and nothing has been tweaked recently—no software updates, no new scripts, no configuration edits. I suspect something malicious slipped in or a runaway process is exhausting resources, but I need solid confirmation and a clean-up fast. What I need you to do • SSH in, profile the load, and isolate the exact processes or connections causing the spike. • Scan thoroughly for root-kits, malware, or hidden cron jobs (tools such as maldet, rkhunter, chkrootkit are welcome, but feel free to use your own). • Patch or remove whatever you find, harden the box, and restart services so every cPanel account comes back online. • Hand me a concise report detailing the root cause, the...

    We are getting multiple OT projects and need more hands to support us in terms of this. I’m consolidating several Industry-grade PCs that run bespoke Python applications into our existing Operational Technology environment. The immediate goal is to create a clean, well-documented integration pathway that lets these machines exchange data safely with the rest of the plant network while respecting every cyber-security control already in place. Here’s what I’ll hand over on day one: current network maps, the Python sources, and a short list of approved protocols (mainly Modbus/RTU). From you I need a streamlined integration plan, the actual Python interface code or refactor, and clear documentation that anyone on the OT team can follow without hunting for tribal knowledge....

    I need a working proof-of-concept that hardens my wireless network by analysing live traffic and flagging hostile activity the moment it appears. The model must reliably catch the attacks that worry me most: Denial of Service (DoS), Man-in-the-Middle (MitM) intrusions, classic packet sniffing, and ARP spoofing. Everything has to run in real time on a modest on-prem machine, so efficient feature extraction and lightweight inference are a priority. The task breaks down naturally into three parts. First, capture and label representative WLAN traffic—public datasets are fine as a starting point, but I also want a small tool that lets me pipe raw pcap streams into the training set so the system can learn my network's quirks. Second, build and train the detection engine: a well-comme...

    I need a field engineer to be physically present at Goa Airport on 16 and 17 February. You must bring a laptop loaded with your preferred terminal software, a complete basic toolkit, and your own console cable so we can move quickly once onsite. The job is straightforward but time-critical: unbox, rack and power up one new router and one new switch, then run through the full console-based configuration, saving clean start-up configs before we hand the network over to airport IT. I will supply the configuration files. We may need to patch into a couple of existing lines for testing, so please be ready to verify link LEDs. Once everything is up, finish with a round of connectivity testing—ping, traceroute and a quick throughput check—to confirm that the airport LAN and upst...

    Japan National DID Number Setup

    Đã xác thực

    I need a Japanese national DID or any other VOIP number that can reliably forward calls to my chosen destination. The line will serve both personal and business purposes, so stability, clear audio and the ability to register the caller ID on common soft-phone or SIP devices is essential. Please supply, activate and demonstrate the number working via simple call-forwarding within the shortest possible time; my preference is ASAP. If you already have an inventory of Japanese DIDs, even better—let me know the formats available and any documentation requirements. Acceptance is straightforward: once I can receive and place test calls through the number without drops or quality issues, the milestone is cleared.

    I’ve built a custom web application and it’s almost ready for production. Before the public rollout, I want a rigorous penetration test that will expose any weakness and help tighten every layer of security. The assessment must be hands-on and realistic, covering the full stack rather than a purely theoretical review. Scope My priorities are clear: • Code review – comb through the source for injection points, authentication flaws, insecure dependencies, and logic errors. • Network-level probing – map open ports, misconfigured firewalls, and potential lateral-movement paths. • Server configuration – evaluate patch levels, TLS setup, permissions, and hardening of the underlying OS and web server. Primary Goal The sole purpose is to imp...
