## What's in every issue

The whole week, in one read. Each issue opens with the week's headline numbers, then goes section by section. Every item says what to do about it, and a section is left out on a week when there is nothing worth saying.

### Exploited this week

The flaws attackers are using right now.

- **Newly confirmed exploited.** Flaws newly confirmed as being exploited this week, and what to do about each one.
- **Exploited in the wild.** The flaws attackers are hitting most often.
- **Surging in the wild.** Flaws whose attack activity jumped well above its usual level this week.
- **The gap.** Flaws being exploited that have not yet made the official exploited lists, so you can patch ahead of them.

### Where attacks are heading

Early signs of what comes next.

- **Biggest movers.** The flaws whose likelihood of being exploited rose most this week.
- **Scanning radar.** What attackers are scanning the internet for.
- **Malware trending.** The malware families most active this week and the infrastructure behind them.
- **Supply-chain spotlight.** Compromised or malicious software packages, on the weeks there are any.

### The wider picture

Context, so the week makes sense.

- **Headline numbers.** The week at a glance, at the top of every issue.
- **The week's big story.** A short note up front on the one story that matters most this week.
- **From around the web.** The week's most important security news, summarised.
- **The Precursor take.** A short view on what it all means and what to do next.

## Questions about the Brief

### How often does the Brief arrive?
Once a week. It is a weekly roundup, not a stream of alerts.

### Do I need a Precursor Intelligence account?
No. The Brief covers the threats everyone faces, so it is useful on its own. An account adds the part about you: your software, your domains and what is exposed online.

### Is it the same as the alerts in the platform?
No. Platform alerts are about the software and domains you track, and arrive by email, in the app or by webhook as soon as we spot something that affects you. The Brief is a weekly summary of the wider picture.

### What is in each issue?
The week's headline numbers, then the flaws newly confirmed as exploited, the ones attackers are hitting most or suddenly much more, exploited flaws not yet on the official lists, the biggest movers in likelihood of attack, what attackers are scanning for, trending malware, any supply-chain incidents, the week's security news and a short take on what it all means. Every item says what to do. It covers the wider picture, not your own organisation.

### What happens on a quiet week?
You get a shorter Brief. A section is left out when there is nothing worth saying, rather than padded.

### How do I unsubscribe?
Email info@precursorintelligence.com from the address you signed up with and we will take you off the list.
