AI-Enhanced Tuoni Framework Targets US Real Estate Firm

🔍 Morphisec observed an AI-enhanced intrusion in October 2025 that targeted a major US real estate firm using the modular Tuoni C2 framework. The campaign began with a Microsoft Teams impersonation and a PowerShell one-liner that spawned a hidden process to retrieve a secondary script. That loader downloaded a BMP file and used least significant bit steganography to extract shellcode, executing it entirely in memory and reflectively loading TuoniAgent.dll. Researchers noted AI-generated code patterns and an encoded configuration pointing to two C2 servers; Morphisec's AMTD prevented execution.

CISA: Critical sudo Linux Vulnerability Actively Exploited

⚠ CISA warns that a critical sudo vulnerability (CVE-2025-32463) is being actively exploited to gain root privileges on Linux systems. The flaw affects sudo versions 1.9.14 through 1.9.17 and can be abused via the -R (--chroot) option to run arbitrary commands as root even for users not listed in sudoers. A proof-of-concept was published in early July and CISA has added the issue to its KEV catalog, requiring federal mitigations by October 20 or discontinuation of sudo.

New Phoenix Rowhammer Bypass Elevates DDR5 Privilege Risk

⚠ The new Phoenix Rowhammer technique reverse-engineers TRR in SK Hynix DDR5 DIMMs to induce controlled bit flips previously believed mitigated. Researchers from ETH Zurich and Google report Phoenix reliably triggers flips across all 15 tested modules, enabling practical exploits such as forged Page Table Entries, RSA-2048 key leakage from co-located VMs, and a sudo-based root escalation. The issue is tracked as CVE-2025-6202.

Phoenix RowHammer Bypasses DDR5 Protections in 109s

⚠️ Researchers at ETH Zürich and Google disclosed a RowHammer variant named Phoenix (CVE-2025-6202) that reliably induces bit flips on SK Hynix DDR5 devices and bypasses on-die ECC and advanced TRR protections. The team demonstrated an end-to-end privilege escalation on a production desktop with default DDR5 settings in as little as 109 seconds. Phoenix takes advantage of refresh intervals that mitigation logic does not sample, enabling flips across DIMM stacks produced between 2021 and 2024. Because DRAM chips cannot be updated in the field, the researchers recommend increasing the DRAM refresh rate to 3× as an immediate mitigation and urge vendors to pursue firmware and hardware countermeasures.

Siemens SINAMICS Drives Privilege Management Vulnerability
