I've proven that you don't need quotes or parentheses in JavaScript

You can overwrite the prepareStackTrace property of the Error object by String prototype's functions and invoke them without parentheses. Then by overwriting the Error and Array prototype it is possible to control the arguments. Combining this behavior, together with some JSFuck-inspired tricks, it is possible to generate arbitrary JavaScript strings and run arbitrary JavaScript with only letters + - = and ,

New Kerberos Abuse Path Discovery - Constrained Delegation without Protocol Transition against SPN-less accounts

I've recently released a blog covering how I discovered a new Kerberos delegation abuse path!

By combining Elad Shamir's Reflective RBCD with James Forshaw's U2U sacrificial user technique, Constrained Delegation without Protocol Transition can now be abused against SPN-less accounts. I also had to add S4U2Proxy + U2U support to Impacket to get this working. :)

The Gentlemen: A closer look at a not-so-gentle ransomware-as-a-service operation

Thumbnail acronis.com
19 Upvotes

Our Threat Research Unit published a breakdown of “The Gentlemen” - a Russian-speaking ransomware-as-a-service group that emerged in mid-2025, reportedly after affiliates split off from established groups like LockBit and Qilin. A few things that stood out from the research:

  • They’re offering affiliates up to 90% of ransom revenue - aggressive even by RaaS standards
  • Claimed 800+ victims across the US and Europe, making them one of the top RaaS groups this year
  • Cross-platform ransomware variants targeting Windows, Linux, NAS, and BSD
  • Active use of EDR-killing tooling - one recent incident involved a custom dropper abusing vulnerable Safetica ProcessMonitor and Lenovo BootRepair.sys drivers (BYOVD)
  • A breach of the group’s own infrastructure gave researchers rare visibility into their affiliate network, tooling, and ties to the broader ransomware ecosystem

Full technical writeup linked below for anyone who wants to dig into the IOCs and affiliate details.
