In case you missed it: Add a colon to your password, ":", because all the stealer logs have colons, so it'll end up splitting your password incorrectly.

During pentests we often have to deal with tasks that can be automated. Some of the best tools for this are ADScan and ADPulse. ADScan performs both enumeration and attack and is capable of analyzing BloodHound data to guide you through the pentest. It works with and without AD creds and can compromise some labs in just 3-5 minutes hackers-arise.com/offensive-secu… @three_cube @_aircorridor #pentesting #redteam

if you run ollama on apple silicon and haven’t updated past v0.19, you’re leaving 2x performance on the table. ollama switched from llama.cpp to apple’s MLX framework. people are reporting 7x decode speed improvements on M4. I run hermes on a mac mini M4. updating ollama was the single biggest performance gain I got this month without spending money. qwen3.5-9B went from sluggish to genuinely usable as a daily driver. ollama --version and update if you’re behind.

そう|Claude Codeで始めるAI自動化
ガチで未来感あった。 中国人エンジニアが、Wi-Fiなしの11時間越境フライトでクライアント案件を全部こなしたらしい。 頼ったのはMacBook Pro M4 64GB 1台と、自作のローカルAIオーケストレーター。 ・機内Wi-Fi 25ドル(約3,800円)は拒否 ・Metaが公開してるオープンソースAI Llama 3.3 70Bをパソコン内で起動 ・1秒71語ペースで案件を処理 着陸前にキュー全消化👇GWの帰りの便で使ってみてはいかがでしょうか?

The RansomISAC published regarding "Zhengzhou 403 Network Technology Co., Ltd.", a cert we reported in 2025 after it was used to sign CobaltStrike. Their investigation seemed like a wild adventure, check it out. ransom-isac.org/blog/dragonbre… 1/3

Microsoft Threat Intelligence
Microsoft Defender detected and protected customers against a new software supply chain compromise affecting the "pytorch-lightning" package and immediately reported the issue to the repository maintainers for takedown: msft.it/6013vJisb. At the time the compromised packages were identified and distributed, Microsoft Defender had proactive detections that blocked the malicious files as Trojan:JS/ShaiWorm.DQ!MTB. For protected environments, Microsoft Defender for Endpoint raised the alert "ShaiWorm malware was prevented". Our assessment indicates that Microsoft continues to provide strong protection coverage and has prevented observed activity indicating attempts to install the modified packages. Microsoft Defender continues to monitor for potential follow-on activity, including suspicious use of potentially exposed cloud credentials across major cloud platforms. Observed activity remains limited to a small number of devices and appear contained to a narrow set of environments. We are also investigating container-based telemetry and registry-related signals that may indicate potential compromise in some scenarios. Microsoft continues to monitor and investigate the issue, with layered protections, broad prevention coverage, and ongoing hunting efforts in place. We will share updates as more information becomes available.
