SafeTech Lab Expands SafeTech CA with CDM Module for Automated Certificate Delivery and Renewal

SafeTech Lab has expanded its corporate Certificate Authority platform SafeTech CA with a new Certificate Delivery Management (CDM) module. The enhancement enables the system to handle the full lifecycle of digital certificates, including issuance, delivery to target devices, installation into appropriate stores, and automatic renewal.

Previously, organizations often relied on custom scripts, manual processes, or separate heavy PKI solutions to manage these tasks. With CDM, the first agent-based subsystem inside SafeTech CA, administrators centrally control agents that independently issue certificates on target nodes, monitor expiration dates, and trigger updates.

The module supports GOST algorithms and does not depend on domain infrastructure, allowing agents to operate in isolated network segments and environments without an LDAP directory. Developers position CDM as a compact alternative to large PKI platforms that are frequently purchased just for basic certificate functions.

All issuance, delivery, and renewal operations are now unified within a single SafeTech CA product. The update also introduces rotation of root and subordinate CA certificates without losing trust in previously issued certificates. Configuration settings can now be modified through a web interface instead of manual file edits.

SafeTech CA has been integrated with HashiCorp Vault, enabling centralized storage and rotation of passwords and credentials for external services and databases. This reduces the risk of credentials remaining in plaintext within configuration files.

In the future, SafeTech Lab plans to increase agent autonomy, allowing administrators to manually trigger certificate issuance and delivery via the web interface and monitor task execution in real time.

Rostelecom Refactors InfoSec Careers: Matching Employee Skills to Evolving Business Priorities

Rostelecom's information security block developed a systematic approach to reassess employee expertise and redirect talent to new roles when business structures change rapidly. In one case, an architect hired for a specific team was reassigned after the unit was disbanded, initially moving to a similar position that did not fully align with his broader competencies. HR-business partner Olga Lapshina examined the specialist's full background, including prior work in audits, methodology development, regulatory documentation, university teaching, and scientific research, plus strong mentoring abilities with younger staff. These skills matched the needs of the methodology department, leading to a transfer supported by an individual development plan and a mentor via the internal Tochka Rosta platform. Within two months the employee contributed improvements that accelerated preliminary InfoSec audits by 30 percent and risk assessments by 20 percent while expanding threat scenario coverage by 10 percent. The initiative demonstrates Rostelecom's emphasis on horizontal career movement and retention of experienced professionals through structured career tracks.

How to Avoid Becoming the Hero of 'My Program Deleted 800 GB': Safe Recursive Deletion in Bash and Python

A recent Habr article examines dangerous patterns in recursive file deletion scripts that have caused massive data loss incidents, including an 800 GB wipe triggered by Telegram Desktop on Windows. The piece analyzes classic mistakes such as empty variables in rm commands and extra spaces that turned single paths into multiple destructive arguments, referencing the 2015 Steam Linux bug and the 2011 Bumblebee installer error. It provides hardened Bash templates using set -euo pipefail, ${VAR:?} checks, realpath validation, and --one-file-system flags to prevent deletion of forbidden directories or symlinked targets. The Python section introduces a safe_rmtree wrapper that enforces root boundaries, rejects symlinks, uses resolve(strict=True), and checks shutil.rmtree.avoids_symlink_attacks before proceeding. Additional recommendations include dry-run modes, marker files, temporary directory usage, and logging to make deletion operations auditable and reversible where possible.

Hackers tamper with refrigeration units in European supermarkets, setting temperatures to +50 °C

Attackers gained unauthorized access to refrigeration and freezer control systems in supermarkets across several European countries, including Sweden, Belgium, Luxembourg, and Estonia. In multiple locations they altered temperature settings to +50 °C, risking widespread spoilage of perishable goods. The incidents primarily affected older, unpatched Danfoss controllers that had been connected to networks for remote maintenance. Estonian manufacturer Kitman Coldtech reported that one attack on a legacy Danfoss system was detected and stopped within approximately ten minutes, preventing any damage. Similar intrusions were confirmed by Swedish chains ICA and Coop, following earlier incidents in French supermarkets in October that resulted in product losses. Experts note that legacy industrial controllers remain attractive targets because they are often left exposed once placed online for convenience.

AmneziaWG Container for MikroTik Routers Delivers Top Performance Six Months After Launch

A developer released an AmneziaWG container for MikroTik devices in February 2026 and has since added major improvements in speed, protocol support, and stability. The lightweight container leverages the router's native WireGuard implementation for cryptography while handling AmneziaWG obfuscation in software. Performance now reaches 250-350 Mbit/s on models such as Hap Ax3 and RB5009B after switching to C code and increasing buffer sizes with RouterOS 7.24. New features include server mode for connecting multiple MikroTik devices, random port hopping, IPv6 support, dynamic DNS, and offline configuration. The project survived an early GitHub ban caused by test scripts and has grown to over 370 stars while remaining fully offline and privacy-focused.
