Z „Igiho stránky o virech“ se stává agregátor veřejných bezpečnostních zdrojů.

Sleduju 52 zdrojů z 13 zemí — národní CERTy ze střední Evropy, výrobce a threat-intel týmy — a skládám je do jednoho chronologického přehledu v češtině. V databázi je 3 033 položek.

Umím toho spoustu, třeba i generovat týdenní reporty, přičemž AI se snaží o agregaci informací tak, aby to nebyla úplná nuda. Více na stránce o projektu.

Using Gemma4 with Ollama - Testing File Hash Analysis and Recommendations with AI, (Wed, Aug 12th)

In the past few weeks, I have been using Gemma4 as a Large Language Model (LLM) to see how useful it can be to analyze some of the malware hashes uploaded to the DShield sensor over the past 30 days and figure out how its recommendation can be considered useful about the activity my DShield sensor is collecting and tracking. The model I use for this testing is gemma4:e4b [2] using two sites to compare the data against VirusTotal and CyberGordon. The following questions were submitted to Gemma…

Qualys Introduces Real-Time Cloud Security Posture Management (CSPM) for Faster Risk Detection and Remediation

Key Takeaways Cloud environments change continuously, while security still relies on periodic scans, leaving gaps where risks go undetected. That gap becomes exposure. Qualys Real-Time CSPM monitors cloud changes as they happen, while still supporting periodic scans for environments that require them. It evaluates each finding in context by correlating posture data with vulnerabilities, asset criticality, and exploitability. Cloud risk is not handled in isolation; it is unified with…

Linux Kernel Process Accounting, (Wed, Aug 12th)

A couple of days ago, Xavier posted about Atuin to gain more insight into the command history. Atuin does a great job of better organizing what is usually handled by "bash_history" and collecting meaningful additional data. Our reader David commented that this can also be done quite well with Linux's kernel process accounting feature, and I think he is very right. I really like Linux process accounting for a number of reasons, so here is a quick introduction. Process accounting is a kernel…

Patch Tuesday: Update now to fix 421 flaws, including three zero-days

Microsoft’s August 2026 Patch Tuesday addresses 421 Microsoft vulnerabilities, including 62 rated Critical. One Windows vulnerability has been exploited in the wild by the Lazarus group to gain SYSTEM privileges. The August update is smaller than July’s record-breaking release, but it’s still among Microsoft’s largest Patch Tuesday batches. More importantly, it includes several flaws likely to attract attacker interest: a publicly disclosed Windows privilege escalation flaw with a proof-of…
