Battering RAM Attack Bypasses Intel and AMD Cloud Security Protections

A group of academics from KU Leuven and the University of Birmingham have demonstrated a new vulnerability called Battering RAM. This vulnerability bypasses the latest defenses on Intel and AMD cloud processors, compromising Intel's Software Guard Extensions (SGX) and AMD's Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP). The attack leverages a custom-built, low-cost DDR4 interposer hardware hack to stealthily redirect physical addresses and gain unauthorized access to protected memory regions. The vulnerability affects systems using DDR4 memory, particularly those relying on confidential computing workloads in public cloud environments. Successful exploitation can allow a rogue cloud infrastructure provider or insider with limited physical access to compromise remote attestation and enable the insertion of arbitrary backdoors into protected workloads. The vulnerability was reported to the vendors earlier this year, but defending against Battering RAM would require a fundamental redesign of memory encryption itself. The attack is an evolution of the previous BadRAM attack, which exploited physical address aliasing to modify and replay encrypted memory on AMD SEV-SNP systems. The Battering RAM attack introduces dynamic memory aliases at runtime, allowing it to bypass Intel's and AMD's mitigations for BadRAM. Researchers from Georgia Institute of Technology and Purdue University have demonstrated a new attack called WireTap that also bypasses Intel's SGX security guarantees. WireTap uses a DDR4 memory-bus interposer to passively decrypt sensitive data, exploiting Intel's deterministic encryption. The WireTap attack can extract an SGX secret attestation key, allowing an attacker to sign arbitrary SGX enclave reports. WireTap and Battering RAM attacks are complementary, focusing on confidentiality and integrity respectively. WireTap can be used to undermine confidentiality and integrity guarantees in SGX-backed blockchain deployments. Intel and AMD have acknowledged the exploits but consider physical attacks on DRAM out of scope for their current products. Intel's cryptographic integrity protection mode of Intel Total Memory Encryption-Multi-Key (Intel TME-MK) can provide additional protection against alias-based attacks. The researchers' exploits demonstrate that confidential computing is not invincible, and defenders should reevaluate threat models to better understand and prepare for physical attacks.

UNC5174 Exploits VMware Zero-Day Privilege Escalation Since October 2024

A China-linked threat actor, UNC5174, has been exploiting a zero-day privilege escalation vulnerability in VMware products since mid-October 2024. The flaw, CVE-2025-41244, affects multiple VMware products and allows local attackers to escalate privileges to root on affected virtual machines. The vulnerability was discovered in May 2025 and patched in VMware Tools 12.4.9 and later versions. The flaw is rooted in the get_version() function, which can be exploited by placing a malicious binary in a writable directory. UNC5174 has been observed using this method to gain elevated access and execute code on compromised systems. The exact payload and nature of the attacks remain unclear. Broadcom has confirmed the patch for the vulnerability in VMware Aria Operations and VMware Tools. NVISO released a proof-of-concept exploit demonstrating privilege escalation on vulnerable VMware software. UNC5174 has been linked to previous attacks on U.S. defense contractors, UK government entities, Asian institutions, and the cybersecurity firm SentinelOne, exploiting vulnerabilities such as F5 BIG-IP CVE-2023-46747 and ConnectWise ScreenConnect flaw. The exploitation of CVE-2025-41244 is considered trivial, potentially benefiting multiple malware strains. NVISO identified the vulnerability in mid-May 2025 during an incident response engagement with UNC5174. Broadcom disclosed three vulnerabilities on September 29, 2025, including CVE-2025-41244. The CVSS severity rating for CVE-2025-41244 is 7.8, classified as high.

CISA Emergency Directive 25-03: Mitigation of Cisco ASA Zero-Day Vulnerabilities

The Cybersecurity and Infrastructure Security Agency (CISA) issued Emergency Directive 25-03, mandating federal agencies to identify and mitigate zero-day vulnerabilities in Cisco Adaptive Security Appliances (ASA) exploited by an advanced threat actor. The directive requires agencies to account for all affected devices, collect forensic data, and upgrade or disconnect end-of-support devices by September 26, 2025. The vulnerabilities allow threat actors to maintain persistence and gain network access. Cisco identified multiple zero-day vulnerabilities (CVE-2025-20333, CVE-2025-20362, CVE-2025-20363, and CVE-2025-20352) in Cisco ASA, Firewall Threat Defense (FTD) software, and Cisco IOS software. These vulnerabilities enable unauthenticated remote code execution, unauthorized access, and denial of service (DoS) attacks. GreyNoise detected large-scale campaigns targeting ASA login portals and Cisco IOS Telnet/SSH services, indicating potential exploitation of these vulnerabilities. The campaign is widespread and involves exploiting zero-day vulnerabilities to gain unauthenticated remote code execution on ASAs, as well as manipulating read-only memory (ROM) to persist through reboot and system upgrade. CISA and Cisco linked these ongoing attacks to the ArcaneDoor campaign, which exploited two other ASA and FTD zero-days (CVE-2024-20353 and CVE-2024-20359) to breach government networks worldwide since November 2023. CISA ordered agencies to identify all Cisco ASA and Firepower appliances on their networks, disconnect all compromised devices from the network, and patch those that show no signs of malicious activity by 12 PM EDT on September 26. CISA also ordered that agencies must permanently disconnect ASA devices that are reaching the end of support by September 30 from their networks. The U.K. National Cyber Security Centre (NCSC) confirmed that threat actors exploited the recently disclosed security flaws in Cisco firewalls to deliver previously undocumented malware families like RayInitiator and LINE VIPER. Cisco began investigating attacks on multiple government agencies in May 2025, linked to the state-sponsored ArcaneDoor campaign. The attacks targeted Cisco ASA 5500-X Series devices to implant malware, execute commands, and potentially exfiltrate data. The threat actor modified ROMMON to facilitate persistence across reboots and software upgrades. The compromised devices include ASA 5500-X Series models running specific software releases with VPN web services enabled. The Canadian Centre for Cyber Security urged organizations to update to a fixed version of Cisco ASA and FTD products to counter the threat. Nearly 50,000 Cisco ASA and FTD appliances are vulnerable to actively exploited flaws. The vulnerabilities CVE-2025-20333 and CVE-2025-20362 enable arbitrary code execution and access to restricted URL endpoints. The Shadowserver Foundation discovered over 48,800 internet-exposed ASA and FTD instances still vulnerable to the flaws. The majority of vulnerable devices are located in the United States, followed by the United Kingdom, Japan, Germany, Russia, Canada, and Denmark. The Shadowserver Foundation's data is as of September 29, indicating a lack of response to the ongoing exploitation activity. Greynoise had warned on September 4 about suspicious scans targeting Cisco ASA devices, indicating upcoming undocumented flaws. CISA's emergency directive gave 24 hours to FCEB agencies to identify and upgrade vulnerable Cisco ASA and FTD instances. CISA advised that ASA devices reaching their end of support should be disconnected from federal networks by the end of September. The U.K. NCSC reported that the hackers deployed Line Viper shellcode loader malware and RayInitiator GRUB bootkit.
