  • Unit 42 Reports PEERSTITCH Implant via FortiGate Exploitation Critical·KEV·CVSS 9.8·EPSS 95%·Unit 42NewRead Attackers used multiple vulnerabilities to deploy memory-resident malware on FortiGate firewalls.

    Attackers initially compromised a FortiManager appliance by exploiting CVE-2024-47575. They then used CVE-2025-61624 to deploy PEERSTITCH, a memory-resident malware on managed FortiGate firewalls. PEERSTITCH communicates via legitimate process traffic, avoiding conventional detection.

    Why it matters. The malware is designed to evade detection by leaving no persistent binaries or opening listening ports. The initial access provided access to configurations and credentials for over 500 managed devices.

    Do this today Review logs for activity related to CVE-2024-47575 and CVE-2025-61624.

Vulnerabilities & Patches 4

  • Docker Hub Vulnerability Allows Impersonation and Image Tampering via PAT High·CVSS 9.4·BleepingComputerNewRead A critical flaw in Docker Hub allowed attackers to impersonate users and manipulate container images using PATs.

    A vulnerability in Docker Hub (CVE-2026-105445) allowed an attacker to impersonate users by exploiting how Personal Access Tokens (PATs) were reassigned during account conversions. This permitted unauthorized actions like pulling, pushing, or deleting images within the target's repositories.

    Why it matters. This flaw represents a software supply chain risk, enabling attackers to publish malicious images under legitimate names. The vulnerability allowed actions within the scope of the compromised token.

    Do this today Review and rotate all Personal Access Tokens used with Docker Hub.

    Affected

  • AhsayCBS: Auth Bypass and Path Traversal Lead to RCE High·CVSS 10.0·Horizon3.aiNewRead Chaining authentication bypass and path traversal in AhsayCBS allows unauthenticated RCE.

    Researchers demonstrated chaining CVE-2026-105133, an authentication bypass in API components, with CVE-2026-105134, a file write path traversal. This combination allows an attacker to create administrator accounts and upload webshells.

    Why it matters. Successful exploitation allows command execution as SYSTEM on Windows or root on Linux. This indicates a critical risk of full system compromise.

    Do this today Apply hotfixes released by Ahsay.

    A flaw in curl's HTTP/2 upload handling allows a malicious server to corrupt the client's memory during an upload process. This vulnerability was demonstrated to allow for client-side code execution.

    Why it matters. Successful exploitation enables an attacker to execute arbitrary code on the machine performing the upload.

    Do this today Upgrade curl to version 8.23.0 or later.

  • Linux Kernel vhost Flaw (CVE-2026-74580) Allows Local Root and Host Escape High·CVSS 8.8·The Hacker NewsNewRead A flaw in the Linux vhost subsystem allows local users to achieve root privileges and potentially escape to the host.

    CVE-2026-74580, named Vghost, is a flaw in the Linux vhost subsystem. This vulnerability permits a local user to read and write kernel memory, resulting in root access. The flaw also presents a vector for an untrusted virtual machine to write to and hijack the host's memory.

    Why it matters. Local privilege escalation and guest-to-host escape capabilities increase the potential impact of a compromised low-privilege account. Immediate mitigation is required to prevent system compromise.

    Do this today Review vendor advisories for patches related to the vhost subsystem.

  • Hirudo Android Malware Replaces Banking Apps to Steal Credentials High·BleepingComputerNewRead Hirudo malware replaces legitimate banking apps with patched versions to bypass security checks and steal credentials.

    Hirudo is an Android malware that replaces legitimate banking applications with modified versions. These patched apps use a hooking engine to bypass security checks such as app-signature and Play Integrity checks. Once active, the malware can steal credentials, capture screen data, and record audio.

    Why it matters. This malware targets the application layer security mechanisms within banking apps, representing an escalation in financial fraud techniques. Defenders must assume device-level integrity checks may be bypassed by the malware's internal processes.

    Do this today Avoid installing APK files from unofficial Android stores.

  • North Korean Group Uses Fraudulent IT Workers to Infiltrate US Sectors High·GBHackersNewRead North Korea utilized fraudulent remote workers and laptop farms to gain persistent access to corporate networks.

    The FBI and CrowdStrike disrupted FAMOUS CHOLLIMA, a North Korean operation placing fraudulent remote IT workers within U.S. companies. The infrastructure allowed operatives to maintain access using genuine corporate endpoints rather than requiring initial exploits. This involved U.S.-based facilitators managing device delivery and connectivity.

    Why it matters. This scheme demonstrates that employment fraud can establish persistent corporate access by compromising the hardware and identity layer. Endpoint artifacts and connectivity patterns must be scrutinized for convergence across unrelated employers.

    Do this today Review endpoint telemetry for hardware or software identifiers that appear across unrelated employee accounts.

  • North Macedonia Police Arrest Suspected Administrator of OLVX Market Medium·The RecordNewRead Law enforcement arrested the suspected administrator of the OLVX cybercrime market in North Macedonia.

    North Macedonian police and the FBI arrested the suspected administrator of the OLVX cybercrime market in a joint operation. OLVX was a market active since 2023 where cybercriminals traded stolen data and credentials. The suspect also allegedly ran a Telegram group named ONEMILI.

    Why it matters. The OLVX market facilitated the sale of personally identifiable information and login credentials, posing a risk to digital security.

  • Credential Compromise Infiltration via Misconfigured VPN Gateway High·GBHackersNewRead Attackers used compromised credentials through a misconfigured VPN to conduct extensive reconnaissance on a European bank's internal systems.

    Threat actors used valid, compromised credentials to gain initial access via a misconfigured, third-party-managed VPN gateway. The activity involved months of reconnaissance, including extensive host and network scanning and repeated password-guessing campaigns against internal systems.

    Why it matters. The incident demonstrates that weak identity controls and perimeter access weaknesses can allow attackers to map and probe internal infrastructure even without advanced zero-day exploitation.

    Do this today Implement phishing-resistant MFA and reduce standing administrative privileges on all access points.
