Osweep - Don't Simply Search Osint, Sweep It

If you lot operate inward information technology security, therefore you lot most probable role OSINT to assistance you lot sympathise what it is that your SIEM alerted you lot on together with what everyone else inward the globe understands most it. More than probable you lot are using to a greater extent than than 1 OSINT service because most of the fourth dimension OSINT volition entirely render you lot amongst reports based on the final analysis of the IOC. For some, that's practiced enough. They do network together with electronic mail blocks, do novel rules for their IDS/IPS, update the content inward the SIEM, do novel alerts for monitors inward Google Alerts together with DomainTools, etc etc. For others, they deploy these same countermeasures based on provided reports from their third-party tools that the fellowship is paying THOUSANDS of dollars for.

The work amongst both of these is that the analyst needs to dig a footling deeper (ex. FULLY deobfuscate a PowerShell ascendency establish inward a malicious macro) to assemble all of the IOCs. And what if the additional IOC(s) you lot are basing your analysis on has nil to do amongst what is truthful most that site today? And therefore you lot larn pwned? And therefore other questions from management arise...

See where this is headed? You're most to larn a pinkish sideslip together with walked out of the edifice therefore you lot tin plough over notice start looking for roughly other task inward a dissimilar describe of work.

So why did you lot larn pwned? You know that if you lot wasted fourth dimension gathering all the IOCs for that 1 warning manually, it would receive got taken you lot one-half of your shift to consummate together with you lot would've got pwned regardless.

The fix? OSweep™.
