PROFILE
Ofek Shaked
Ofek Shaked developed core security and observability features for the aquasecurity/tracee repository, focusing on kernel-level tracing and event monitoring. Over ten months, he engineered extensible eBPF-based frameworks for syscall and memory event detection, refactored kernel symbol management for deterministic tracing, and enhanced network and file event observability. His work included optimizing log handling with regular expressions, improving build system flexibility using Makefile scripting, and strengthening compatibility across kernel versions. Leveraging C, Go, and shell scripting, Ofek consistently delivered maintainable, testable solutions that improved trace fidelity, reduced false positives, and enabled rapid onboarding of new security and monitoring capabilities.

Sep 1, 2025Month 2025-09: Focused on enhancing build flexibility for the tracee repository. Delivered a dynamic Makefile extension mechanism that conditionally includes Makefile.extended-pre and Makefile.extended-post when present, removing dependence on .extended-build and enabling runtime-determined build types. This reduces configuration friction, improves cross-environment consistency, and supports easier onboarding for new build variants. No major bugs fixed this month; maintenance emphasis on reliability and configurability. Skills demonstrated include Makefile scripting, conditional logic, and build-system modernization, contributing to faster, safer releases and improved developer productivity.

Feb 1, 2025February 2025 monthly summary for aquasecurity/tracee. Delivered two key enhancements in eBPF tracing: a new security_task_prctl syscall tracing probe enabling detailed memory management and security bit settings visibility; and a refactor of thread stack identification to use address-based verification, improving accuracy and reliability. These improvements enhance threat detection and incident response by providing richer, more accurate observability with lower false negatives. Technologies demonstrated include eBPF, tracee event parsing, and data structure design for security events. The changes were implemented with commits 94a51af64e0cf7f5b8355ce271add0c221c11504 and 5a727b302d51cfac514991464b57fb50e1a5afb8.

Dec 1, 2024Month 2024-12 highlights focused on improving kernel symbol handling in aquasecurity/tracee, delivering a more reliable and scalable symbol resolution path that underpins robust system-call tracing. Key outcomes: - Kernel Symbol Table Improvements: Consolidated kernel symbol handling into a generic, memory-efficient KernelSymbolTable with an adaptable storage mode. This enables deterministic symbol reporting for hooked_syscall events by correctly associating symbols with their syscall addresses and supports future symbol management. - Symbol data control: Introduced a flexible storage policy via a requiredDataSymbolsOnly flag, allowing the symbol table to store all symbols or only non-data symbols as needed, with required data symbols registered prior to updates. - Reliability and determinism: Fixed nondeterministic symbol assignment for hooked_syscall events when multiple symbols could reside at the same address by emitting an event for each found symbol, reducing test flakiness and improving trace fidelity. Impact: - Improved symbol lookup performance and reduced memory overhead for kernel symbol management, enabling scalable tracing in high-load scenarios. - More stable and deterministic event generation, leading to trustworthy test outcomes and easier maintenance. Technologies/skills demonstrated: - Kernel symbol management, memory-efficient data structures, and a generic symbol table design. - Changes to event emission logic to ensure determinism across module load/unload cycles. - Clear attention to business value: reliability of traces, test stability, and scalable symbol resolution.
