Summary

Hide ▲

A critical command injection vulnerability in SAP S/4HANA (CVE-2025-42957) is being actively exploited in the wild. The flaw, with a CVSS score of 9.9, allows attackers with low-privileged user access to execute arbitrary ABAP code, bypass authorization checks, and fully compromise the SAP environment. This can lead to data theft, fraud, or ransomware installation. The vulnerability affects both on-premise and Private Cloud editions of SAP S/4HANA, as well as several other SAP products and versions. SecurityBridge Threat Research Labs discovered the vulnerability and reported it to SAP on June 27, 2025. The vendor fixed the vulnerability on August 11, 2025, but several systems have not applied the available security updates and are now being targeted by hackers. Exploitation activity surged dramatically after the patch was released. Organizations are advised to apply patches immediately, monitor logs for suspicious activity, and implement additional security measures.

    Active Exploitation of SAP S/4HANA Command Injection Vulnerability (CVE-2025-42957) Observed

    SecurityBridge confirmed actual abuse of the vulnerability in the wild. Pathlock detected outlier activity consistent with exploitation attempts. Exploitation activity surged dramatically after the patch for CVE-2025-42957 was released. The vulnerability is especially dangerous due to its low attack complexity and network exploitability. An attacker can gain administrative privileges with one user account and a remote function call (RFC). Attackers can manipulate or delete corporate data, create persistent backdoors, and exfiltrate data. SecurityBridge recommended implementing SAP's Unified Connectivity framework (UCON) to restrict RFC usage and advised monitoring logs for suspicious RFC calls and newly created admin accounts.

Phoenix Rowhammer attack bypasses DDR5 Rowhammer defenses

A new Rowhammer attack variant, called Phoenix, bypasses the latest protection mechanisms on DDR5 memory chips from SK Hynix. This attack exploits vulnerabilities in the Target Row Refresh (TRR) mechanism to flip bits in memory, enabling privilege escalation and unauthorized access. The attack was developed by researchers at ETH Zurich University and Google, and it affects all DDR5 DIMM RAM modules produced between January 2021 and December 2024. The Phoenix attack can corrupt data, increase privileges, execute malicious code, or access sensitive data. It works by repeatedly accessing specific rows of memory cells to cause electrical interference, altering nearby bits. The attack is tracked as CVE-2025-6202 and has been assigned a high-severity score. The researchers demonstrated the attack's effectiveness by successfully flipping bits on all 15 DDR5 memory chips in their test pool, achieving root privileges in under two minutes. They also showed that the attack can break SSH authentication and alter system binaries to escalate local privileges. The researchers recommend increasing the refresh rate to 3x to mitigate the Phoenix attack.

UNC6040 and UNC6395 Target Salesforce Platforms in Data Theft Campaigns

The FBI has issued an alert about two cybercriminal groups, UNC6040 and UNC6395, targeting Salesforce platforms for data theft and extortion. UNC6395 exploited compromised OAuth tokens for the Salesloft Drift application, while UNC6040 used vishing campaigns and modified Salesforce tools to breach Salesforce instances. Both groups have been active since at least October 2024, impacting multiple organizations. UNC6040 has been linked to extortion activities, with Google attributing these to a separate cluster, UNC6240, which has claimed to be the ShinyHunters group. The ShinyHunters group, along with Scattered Spider and LAPSUS$, recently announced they are going dark, but experts warn that the threat persists. UNC6040 impersonated corporate IT support personnel to gain access to Salesforce environments and used modified versions of Salesforce's Data Loader to exfiltrate data. Salesforce re-enabled integrations with Salesloft technologies, except for the Drift app, which remains disabled.

Fourth Spyware Campaign Targeting French Apple Users in 2025

Apple has notified French users of a fourth spyware campaign in 2025. The Computer Emergency Response Team of France (CERT-FR) confirmed the alerts on September 3, 2025. The campaign targets individuals based on their status or function, including journalists, lawyers, activists, politicians, and senior officials. The alerts are part of a series of notifications sent throughout the year, with previous alerts on March 5, April 29, and June 25. These alerts indicate that at least one device linked to the users' iCloud accounts may have been compromised in highly-targeted attacks. The campaign follows a previous incident involving a security flaw in WhatsApp (CVE-2025-55177) and an Apple iOS bug (CVE-2025-43300), which were used in zero-click attacks. Apple has been sending these notifications since November 2021. Apple introduced Memory Integrity Enforcement (MIE) in the latest iPhone models to combat memory corruption vulnerabilities.

New HybridPetya Ransomware Exploits UEFI Secure Boot Bypass Vulnerability

A new ransomware variant, HybridPetya, has been discovered. It resembles the Petya/NotPetya malware but includes the ability to bypass UEFI Secure Boot using the CVE-2024-7344 vulnerability. HybridPetya encrypts the Master File Table (MFT) on NTFS-formatted partitions and can compromise modern UEFI-based systems. The ransomware operates through a bootkit and an installer, with the bootkit managing encryption and decryption processes. The ransomware has been observed in samples uploaded to VirusTotal in February 2025, with no evidence of active use in the wild. The vulnerability exploited by HybridPetya was patched in January 2025. The ransomware encrypts the MFT and displays a fake CHKDSK message to deceive victims. It demands a $1,000 ransom in Bitcoin, with a total of $183.32 received between February and May 2025. The ransom note provides an option for victims to enter a decryption key after payment, which triggers the decryption process. The bootkit also recovers legitimate bootloaders from backups created during installation. The ransomware triggers a system crash during bootloader changes, ensuring the bootkit binary is executed upon reboot. HybridPetya may be a research project, proof-of-concept, or early version of a cybercrime tool under limited testing. HybridPetya combines the destructive capabilities of NotPetya, the recoverable encryption functionality of Petya ransomware, and the ability to bypass Secure Boot protections. It can deploy malicious UEFI payloads directly to the EFI System Partition and encrypt the Master File Table (MFT). HybridPetya's ability to install harmful code directly into a computer's UEFI firmware makes it hard for security teams to detect. The emergence of HybridPetya highlights the growing threat from UEFI bootkits that reside at a computer's startup sequence level.

Active exploitation of CVE-2025-5086 in DELMIA Apriso

CVE-2025-5086, a critical deserialization flaw in Dassault Systèmes DELMIA Apriso Manufacturing Operations Management (MOM) software, is being actively exploited. The vulnerability, with a CVSS score of 9.0, affects versions from Release 2020 through Release 2025. Exploitation attempts have been observed, targeting the /apriso/WebServices/FlexNetOperationsService.svc/Invoke endpoint with a Base64-encoded payload. The payload decodes to a GZIP-compressed Windows executable that deploys a malicious program designed to spy on user activities. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added the flaw to its Known Exploited Vulnerabilities (KEV) catalog, advising Federal Civilian Executive Branch (FCEB) agencies to apply updates by October 2, 2025. The malware, identified as Trojan.MSIL.Zapchast.gen, captures keyboard input, takes screenshots, and gathers information about active applications. This information is then sent to the attacker via various means, including email, FTP, and HTTP. The exploit involves sending a malicious SOAP request to vulnerable endpoints. The malicious requests were observed originating from the IP 156.244.33[.]162.
