📰 AI Helped Uncover A "50-80x Improvement" For Linux's IO_uring
Linux block maintainer and IO_uring lead developer Jens Axboe recently was debugging some slowdowns in the AHCI/SCSI code with IO_uring usage. When turning to Claude AI to help in sorting through the issue, patches were devised that can deliver up to a "literally yield a 50-80x improvement on the io_uring side for idle systems." The code is on its way to the Linux kernel...

⚡ 25,000 U.S. businesses already use macOS, and the number keeps growing. Yet macOS threats are still flying under the radar for most security teams.
Attackers know this. 👀 And they're quietly adding more cross-platform threats to take advantage of it, targeting sensitive data.
That's exactly why #ANYRUN just levelled up. The sandbox now supports #macOS alongside #Windows, #Linux, and #Android — one unified place, full visibility, faster verdicts.

🚨 Update Your Detection Rules: New Remote Access Trojan
We caught a Go-based RAT and named it #Moonrise. At the time of the analysis, the sample had not yet been submitted to VirusTotal ❗️
The level of access enables credential harvesting, sensitive data collection, and preparation for further compromise without triggering static detections, leaving SOCs with no clear signals to act on.
⚠️ Observed capabilities include:
🔹 Privilege-related functions and persistence mechanisms
🔹 Data theft and credential harvesting
🔹 Process control and command execution
🔹 File upload and execution
🔹 User activity monitoring: screen capture and streaming, webcam and microphone access, keystroke logging, clipboard monitoring
One compromised endpoint can disrupt operations and lead to financial and reputational damage.

✅ Behavior-first triage in #ANYRUN Sandbox lets security teams confirm attacker actions, like remote command execution, UAC bypass attempts, and persistence-related activity, within minutes. Security teams reduce Tier-1 overload and unnecessary escalations, while containing incidents earlier.

JSGuLdr: Multi-Stage Loader Delivering PhantomStealer
#ANYRUN researchers identified #JSGuLdr, a multi-stage JavaScript-to-PowerShell loader used to deliver #PhantomStealer. A JScript file triggers PowerShell through an Explorer COM call, pulls the second stage from %APPDATA%\Registreri62, then uses Net.WebClient to fetch an encrypted payload from Google Drive into %APPDATA%\Autorise131[.]Tel. The payload is decoded in memory and loaded, with PhantomStealerinjected into msiexec.exe.
Execution chain: wscript.exe ➡️ explorer.exe (svchost.exe) ➡️ explorer.exe (COM) ➡️ powershell.exe ➡️ msiexec.exe
