flyto_core versions 2.26.7 and earlier contain a Server-Side Request Forgery (SSRF) vulnerability that allows attackers to induce the server to make unintended requests. This can potentially lead to unauthorized access or information disclosure. The vulnerability affects all versions up to and including 2.26.7.
A new Mirai-based modular Linux botnet malware called Evooo1Bot has been targeting internet-facing gateway devices, turning them into SOCKS5 traffic relay nodes. [...]
This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The ZDI has assigned a CVSS rating of 7.5.

A couple of days ago, Xavier posted about Atuin to gain more insight into the command history. Atuin does a great job of better organizing what is usually handled by "bash_history" and collecting meaningful additional data. Our reader David commented that this can also be done quite well with Linux's kernel process accounting feature, and I think he is very right. I really like Linux process accounting for a number of reasons, so here is a quick introduction.
UNIX systems (including Linux) are well-known to record a lot of activities in many different locations. But there is one domain where they definitely lack of "modern" logging: shells. Most shells provide an historization of the typed commands through a flat file in the $HOME directory (ex: $HOME/.bash_history). They suffer of multiple problems:
Researchers found a way to bypass recent mitigations for Spectre v2 speculative execution side-channel attacks and developed an exploit to leak secrets from Linux machines. [...]
The Arch Linux project has temporarily disabled adoption of Arch User Repository (AUR) packages after a surge in malicious takeovers of existing packages. [...]
In May 2026, a sophisticated Monero cryptomining campaign was identified targeting Linux environments. Attackers gained initial access through trusted third-party relationships, then escalated to root privileges. Rather than operating openly as root, they weaponized Linux Pluggable Authentication Modules (PAM) to impersonate multiple low-privileged users, creating a forensic smokescreen and establishing redundant persistence through cronjobs. The operators suppressed system logging and deployed a customized XMRig 6.25.0 implant that self-unlinks after execution, running entirely in memory. The binary uses XOR encryption for configuration obfuscation and employs process masquerading to blend with legitimate processes. Campaign tracking revealed operations linked to the V25 Generation 26 family, connecting to the domain unable.download for mining pool communication.
BlueShell is an open-source remote access trojan developed in Go language, primarily used by Chinese-based threat actors. A variant of BlueShell has been identified in post-intrusion activities by APT groups including BlackTech, targeting organizations in Japan, South Korea, and Thailand. This variant differs from the original through a dedicated dropper mechanism, proxy server-based C2 communication, and anti-forensic capabilities. The dropper deploys the variant to /tmp/kthread, disguises it as a Linux kernel worker process, and removes filesystem traces. Recent variants observed since 2024 include XOR-encoded configuration data and proxy functionality, indicating continuous development. The malware performs hostname verification, validates C2 certificates, and implements commands for file transfer, remote shell, and SOCKS5 proxy capabilities.
In the Linux kernel, the following vulnerability has been resolved: net/sched: cls_api: Handle TC_ACT_CONSUMED in tcf_qevent_handle tcf_classify() can return TC_ACT_CONSUMED while the skb is held by the defragmentation engine (e.g. act_ct on out-of-order fragments). When that happens the skb is no longer owned by the caller and must not be touched again. tcf_qevent_handle() did not handle TC_ACT_CONSUMED: it fell through the switch and returned the skb to the caller as if classification had passed. The only qdisc that wires up qevents today is RED, via three call sites (qe_mark on RED_PROB_MARK/HARD_MARK, qe_early_drop on congestion_drop) red_enqueue() was continuing to operate on an skb it no longer owns in this case -- enqueueing it, dropping it, or updating statistics. Resulting in a UAF. tc qdisc add dev eth0 root handle 1: red ... qevent early_drop block 10 tc filter add block 10 ... action ct (with ct defrag enabled and traffic that produces out-of-order fragments, e.g. a fragmented UDP stream) Handle TC_ACT_CONSUMED in tcf_qevent_handle() the same way the ingress and egress fast paths do: treat it as stolen and return NULL without touching the skb. Unlike the TC_ACT_STOLEN case, the skb must not be dropped/freed here, as it is no longer owned by us.

For the latest discoveries in cyber research for the week of 13th July, please download our Threat Intelligence Bulletin. TOP ATTACKS AND BREACHES U.S. auto insurer AssuranceAmerica has disclosed a data breach affecting approximately 7 million people. Attackers targeted an employee and used compromised credentials to access company systems, stealing names, contact information, driver’s license numbers, insurance policy and account data, vehicle information, and claims details. Latvia’s state-owned forestry company Latvijas Valsts Meži has suffered a ransomware attack that disrupted mapping, hunting, contractor, and customer systems. Attackers exploited a system that had remained unpatched for two years and leaked approximately 44GB of internal documents, credentials, cryptographic keys, source code, and email correspondence. Injective Labs, a developer of blockchain and cryptocurrency software, has experienced a supply chain compromise after attackers accessed its SDK project and published malicious npm packages. The affected releases exfiltrated cryptocurrency wallet private keys and seed phrases when developers used legitimate key-generation functions embedded in the compromised software. Moody Bible Institute, a U.S. faith-based educational institution, has disclosed a data breach affecting more than 2.3 million donors, students, alumni, and supporters. The ShinyHunters extortion group published allegedly stolen information, including names, dates of birth, residential addresses, email addresses, and phone numbers. AI THREATS Researchers profiled JadePuffer, an autonomous ransomware operation that used a large language model to conduct an intrusion without direct human control. The operation exploited CVE-2025-3248 in an exposed Langflow instance, accessed a production MySQL server, exfiltrated selected information, deleted the database, and issued an extortion demand. Researchers showed that malicious instructions hidden inside open-source project files could achieve remote code execution through Anthropic Claude Code and OpenAI Codex. When operating with automated permissions, the coding agents processed the instructions and executed attacker-controlled scripts, demonstrating a risk that may affect other autonomous development tools. Researchers disclosed Rogue Agent, a vulnerability in Google Dialogflow CX that allowed users with limited agent-editing permission to insert persistent malicious code. The injected code could capture and exfiltrate chatbot conversations. Google addressed the issue, and no known customer environments were compromised through the vulnerability. VULNERABILITIES AND PATCHES Multiple Tenda router models are affected by CVE-2026-11405, an undocumented authentication backdoor that provides administrative access through a hidden password. The flaw affects several FH1201, W15E, AC10, AC5, and AC6 firmware versions and allows attackers to bypass configured credentials and modify device and network settings. Linux maintainers have patched CVE-2026-53359, a critical vulnerability in the Kernel-based Virtual Machine hypervisor. A malicious guest virtual machine could corrupt host kernel memory and potentially escape into the host environment. The flaw affects Intel and AMD x86 systems and is particularly relevant to shared cloud infrastructure. U-Boot has addressed six vulnerabilities affecting signature verification of Flattened Image Tree files used during secure boot. Two flaws could enable arbitrary code execution while a device loads a supposedly verified image, and four could cause crashes. The affected bootloader is widely used in routers, cameras, and embedded controllers. Opera has addressed a critical vulnerability in the Opera GX browser that allowed malicious websites to install browser modifications without user confirmation. An attacker-controlled modification could inject styles across open tabs, leak information such as Gmail addresses, and crash the browser. Opera corrected the issue. TH…
