I usually don't drink on weekdays, but hear me out: Over the weekend, I thought about a common conditional access misconfiguration I often see in the wild. I decided to write a blog post about it, but that got me thinking: Is that the best way to reach as many tenant admins as possible? That gave me the following idea: What if I write a ๐Ÿ”ฅMaester test for it? Now, as a non-developer, that might be out of your comfort zone, but with the help of @merill and @Thomas_Live, I quickly got this new test added to the existing repository, ready to hit hundreds or thousands of tenants. Dare to (th)(dr)ink different. ๐Ÿ”ฅ ๐Ÿ“– [Blogpost] janbakker.tech/conditional-acโ€ฆ ๐Ÿš€ [Contribute to Maester] maester.dev/docs/contributโ€ฆ

Great reminder for anyone wanting to enrich their Kusto queries with additional information. If you are after enrichment such as geo info for IPs, ASN lookup info, tor exit node data and more, then have a look below. The KQL is already written for you - firewalliplists.gypthecat.com/kusto-tables/
Aura@SecurityAura

A special thanks to @reprise_99 who showed me @gypthecatdotcom and it's Kusto ASN Table lists and references! Definitely something everyone should be aware of and start using in their queries for enrichment and additional filtering opportunities! firewalliplists.gypthecat.com/kusto-tables/

RansomCow ๐Ÿ„
Hackmanac@H4ckmanac

A #Ransomware Attack Killed a Cow and Her Calf. In the Swiss canton of Zug, a ransomware attack on a farmer's computer systems, including a milking robot, resulted in the death of a cow and her calf. The cybercriminals demanded 10,000 Swiss Francs ($10,800) for decryption, but the farmer chose not to pay. Although the milking robot continued functioning without the network connection, the farmer could not access vital data, leading to the delayed detection of the cow's distress. The monetary damage, excluding the ransom, amounted to over โ‚ฌ6,400. Read more: heise.de/en/news/Switzeโ€ฆ #CyberAttack #CyberSecurity #Hack
