Editor's Notes
- It was getting dark and our hacker hero was tired of looking at multiple online code repositories. Before he closes his 30 tabbed browser, he stumbled upon an unusual repository. What intrigued him was that the code repo had less code, but lots of releases. After downloading, decompiling and hours of debugging, he found the slack token of the target organization. Using the slack token, he was able to get messages from most of the Slack channels of the target organization.
- This has happened even to one of the best companies among us
- Data could be scattered on multiple places or could get it in a single place Is not confined to a bunch of tools which call them the best OSINT tool
- Let us forget the organizations we work with for some time

- hunter.io - get the email format. Is it {firstname}.{lastname}@company.com or {firstname}@company.com. If you find the pattern, with the help of LinkedIn you could actually get all emails of employees HIBP - was this email leaked in some previous breach ? If yes, can we get the credentials from the breach ?

- Know yourself Since you can look into your digital assets, make sure it is configured properly Remove DNS records when no longer used Think like an attacker Always think how the public information could be used against your company Proper compartmentation Without proper compartmentation, attackers are able to leverage information from one compromised account to access another related account. Vulnerability Management A good vuln mgmt covers all assets. Vuln mgmt tools will find easily exploitable vulns Employee awareness You cannot control the employees’ personal online accounts All you can do is give provide general awareness of how posting company data online / reusing passwords could be tragic ---- Have different accounts for different env HaveIBeenPwned - free updates --- Devils advocate (policies, Data Loss Prevention)
