A fake cryptocurrency trading app called Padre Terminal, previously available on the Apple App Store for iOS devices, has been linked to the theft of approximately $23,000 from 27 Solana wallets. Blockchain investigator Iris confirmed that one victim was compromised through the malicious App Store app, but has not determined how the other affected wallets were compromised. The researcher says the app drains wallets after unsuspecting users import their private keys into it. Padre was a cryptocurrency trading platform, mainly used to buy and sell meme coins on Solana. It was later renamed Terminal by pump.fun, a platform focused on creating, buying, and selling cryptocurrency “meme coins” on the Solana blockchain. Iris says the legitimate Padre trading service, now Terminal by pump.fun, is web-only, so any mobile apps impersonating it, including the one previously available on the App Store, are malicious.
A newly identified advanced persistent threat (APT) group tracked as UAT-11473 was observed exploiting CVE-2026-20127, an authentication-bypass flaw in Cisco Catalyst SD-WAN Controllers, to deploy a custom malware framework called KeyDrift. CVE-2026-20127 is a max-severity flaw that Cisco patched in February 2026, which allows remote attackers to gain privileged access to Catalyst SD-WAN Controller and Manager and add rogue peers. UAT-8616 has exploited the vulnerability as a zero-day since at least 2023, and recent research also linked its exploitation to the Chinese Volt Typhoon state-sponsored hacking group. According to Cisco Talos researchers who reported on the activity, the UAT-11473 threat cluster appears to overlap with Volt Typhoon’s "Silent Train" covert access network, but they made no definitive links.
U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Linux Kernel and Broadcom VMWare ESX flaws to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added Linux Kernel and Broadcom VMWare ESX vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog: Below are the flaws added to the catalog: CVE-2026-41709 (CVSS score of 7.6) Broadcom VMWare ESX Insufficient Logging Vulnerability CVE-2026-46300 (CVSS score of 2.7) Linux Kernel Missing Initialization of a Variable Vulnerability In July, Broadcom released patches to address five vulnerabilities affecting VMware ESXi, vCenter, Workstation, and Fusion, including CVE-2026-41709. The vulnerability in VMware ESX is caused by insufficient logging. A malicious user with administrator privileges could perform certain operations on the affected system without those actions being recorded in the logs. This could allow an attacker to hide specific activities and make it harder for security teams to detect suspicious behavior, investigate incidents, and determine what happened. The flaw does not itself grant administrator privileges; the attacker must already have them. According to CrowdStrike’s 2026 Legal Threat Landscape Report, which said the China-linked threat actor Warp Panda (aka Armory Castle, UNC5221, Clay Typhoon and VerdantBamboo) exploited CVE-2026-41709 as a zero-day in early 2026 to reduce the visibility of its activities in audit logs. Warp Panda targets internet-facing edge devices by exploiting zero-day vulnerabilities and deploying custom malware to maintain persistent, covert access. The group also attempts to evade detection by bypassing audit logging, stealing cloud session tokens and registering unauthorized multi-factor authentication (MFA) devices. The second flaw added to the catalog is CVE-2026-46300, also known as Fragnesia, could let local attackers gain root access through page cache corruption. The flaw affects the XFRM ESP-in-TCP subsystem and could allow local attackers to gain full root access by corrupting the kernel page cache. Security experts warn that the issue is dangerous because attackers with low privileges can modify read-only files in memory and take complete control of vulnerable systems. The vulnerability was discovered by William Bowling of the V12 security team, while Wiz published a detailed technical analysis. “The vulnerability allows unprivileged local attackers to modify read-only file contents in the kernel page cache.” reads the report published by Wiz. “Attackers can then achieve root privileges through deterministic page-cache corruption.” Fragnesia shares similarities with earlier Linux privilege escalation flaws, such as Dirty Frag and Copy Fail. According to researchers, the bug can reliably provide root access on major Linux distributions without requiring race conditions or complicated timing attacks. According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog. Experts also recommend that private organizations review the Catalog and address the vulnerabilities in their infrastructure. CISA orders federal agencies to fix CVE-2026-41709 by November 11, 2026, while CVE-2026-46300, must be fixed by October 31, 2026.

Microsoft has resolved a known issue that prevents non-admin users from connecting to devices via Remote Desktop when the "Administrator protection" security feature is enabled. When Administrator protection is enabled, it prompts standard users to authenticate with Windows Hello (PIN or biometric) when they try to change the Windows Registry or install new apps. This feature began rolling out in October 2025 and is now enabled by default in organizations using Windows security baselines after installing the October 2026 Windows security update. Microsoft acknowledged on October 13 that Remote Desktop connections may fail with error 0xC000000D after installing the KB5124010 September 2026 non-security preview update (or Windows updates released since then) on systems running Windows 11 24H2 and later.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) warned federal agencies to patch a high-severity Linux kernel privilege escalation bug that attackers are chaining with the PHP2Shell flaws in the wild. Tracked as CVE-2026-46300 and known as Fragnesia, this vulnerability stems from a logic bug in the Linux XFRM ESP-in-TCP subsystem that lets attackers run malicious code with root permissions. Fragnesia belongs to the Dirty Frag vulnerability class and has a proof-of-concept (PoC) exploit that local attackers can use to gain root privileges on major Linux distributions with kernels released before May 13, 2026. CISA added CVE-2026-46300 to its Known Exploited Vulnerabilities (KEV) Catalog on Wednesday and ordered federal agencies to patch their systems by Saturday 10, as mandated by its Binding Operational Directive (BOD) 26-04.
Microsoft released the KB5127936 preview cumulative update for Windows 11 versions 25H2 and 26H2, with 41 changes, including File Explorer and Cloud rebuild improvements. KB5127936 is a preview update that adds new features and fixes at the end of each month, letting IT admins and users test them before they roll out to the entire user base during next month's Patch Tuesday. However, unlike regular Patch Tuesday cumulative updates, monthly preview updates are optional and don't include security patches. The October 2026 preview update makes the File Explorer context menu faster and easier to customize, letting users choose which app extensions and commands appear and how they're organized. After you install KB5127936, Cloud rebuild can also reinstall Windows without USB media or a custom image, using an image and drivers downloaded directly from Windows Update, even when Windows won't start.
Cisco released security updates to patch a denial-of-service zero-day in Adaptive Security Appliance (ASA) and Threat Defense (FTD) software that attackers are exploiting to remotely crash vulnerable firewall devices. Tracked as CVE-2026-76418, this high-severity vulnerability affects devices running ASA and FTD software with configurations containing the 'webvpn' keyword and SSL VPN enabled on at least one interface. Successful exploitation allows unauthenticated, remote attackers to trigger a denial-of-service (DoS) condition, causing the device to reload unexpectedly. Cisco advised customers to patch vulnerable firewalls after its Product Security Incident Response Team (PSIRT) discovered evidence that the flaw was being exploited in the wild earlier this month. However, the company didn't provide indicators of compromise and hasn't shared additional information about the attacks, including which organizations are being targeted or who is exploiting the flaw.
Volt Typhoon used disposable relay chains to hide zero-day attacks on critical systems. Lumen linked Silent Train to at least four zero-days. Lumen’s Black Lotus Labs has spent three years tracking a covert network it calls Silent Train, which it ties to Volt Typhoon, the China-linked APT group. The cybersecurity firm says the network hid exploitation of software flaws the vendors didn’t know about yet. Black Lotus sent hundreds of victim notifications along the way, and the investigations that followed revealed the exploitation of at least four confirmed zero-days and one likely. “Volt Typhoon’s Silent Train is a covert network designed to gain and maintain access to the technologies businesses rely on to manage devices, networks and critical operations.” reads the report published by Lumen. “Black Lotus Labs® tracked how the group used rapidly changing chains of compromised infrastructure to conceal its activity while exploiting previously unknown vulnerabilities in centralized management platforms.” Silent Train first showed up in November 2023, shortly before the first takedown of the KV-botnet, Volt Typhoon’s earlier network of hijacked routers. Activity rose after the second disruption. The group dropped persistent infrastructure and moved to disposable chains of compromised devices that it could rebuild whenever it wanted. Each session began on a rented server outside the United States. It then passed through another server and compromised small-office routers, home devices and IoT equipment in other countries. Finally, the traffic passed through a compromised device in the U.S., close to the target. This helped the attackers make their activity look like normal local traffic and bypass location-based blocks and IP reputation filters. On average, the chains passed through about four devices before reaching a U.S. IP address. Some used as many as six. Lumen identified more than 27 types of devices used in the network, including TP-Link routers and Fortinet appliances. Some of these devices had no known vulnerabilities, suggesting that Volt Typhoon may have used previously unknown exploits to compromise them and create relay points. “We observed more than 27 device classes exploited and used in Silent Train operations, ranging from SOHO and IoT devices like TP-Link routers and Netgear Orbi devices to enterprise platforms like Fortinet appliances and CyberPanel servers.” the report continues. “Some relay device types lack known vulnerabilities, suggesting Volt Typhoon leveraged undisclosed zero-day exploits to set up a single relay in a four-to-six hop chain and indicating a willingness to commit significant resources to protecting future access capabilities.” The attackers exploited exposed web interfaces and installed only the tools needed to connect the devices through SSH. These included temporary SSH services, keys, configuration files and tools already available on the systems. At the end of each session, they removed all traces of their activity and dismantled the relay chain. Sessions lasted about four hours on average, although some lasted only minutes. The attackers could also build a new chain in less than two minutes, suggesting that they had partly automated the process. The group worked with strict discipline. New device types arrived about one per quarter, and about one per month during the 2023 and 2024 build-out, always tested outside the U.S. first. Roles never changed: Intelbras modems served only as overseas relays, Netgear Orbi devices only as the U.S. hops facing victims, and the server providers stayed separated by layer too. By early 2025, enterprise platforms like Fortinet, Cisco, PRTG, Mirth Connect and CyberPanel joined as final hops. They stayed up one to three months and supported several intrusions. The group also added reverse tunnels using the open-source proxies Chisel and FRP, and the old and new methods ran in parallel. Volt Typhoon used Silent Train only during key stages of its attacks, including exploiting vulnerabilities, stealing credentials and data, and maintaining access to compromised systems. Each session targeted between one and five victims, often just one organization. The activity was carried out by human operators, mainly from Monday to Friday, between 9 a.m. and 10 p.m. China Standard Time. The group also paused operations for several weeks around Chinese New Year. The group targeted tools used to manage endpoints and networks, as well as SD-WAN systems and other control platforms. These systems can manage hundreds or thousands of devices, allowing attackers to reach many systems without moving through the network in the usual way. This approach also helped them leave fewer traces. After the attacks, investigators found webshells running in memory, stolen credentials, misuse of built-in features such as remote file transfers, and deleted logs. The four confirmed zero-day campaigns hit Versa Director in 2024, N-able N-central through CVE-2025-8875 and CVE-2025-8876, Cisco Catalyst SD-WAN through CVE-2026-20127, and VeloCloud Orchestrator through CVE-2026-16812. The Cisco bug is a CVSS 10.0 flaw, and the group kept exploiting it well after Cisco disclosed it in February 2026. In the Versa case, the group used an in-memory JAR webshell to limit forensic evidence and reach downstream customers. The likely fifth is Quest KACE. The campaign hit more than 30 victims and faded after Quest’s October 2025 security updates. “The campaign affected more than 30 victims, followed vendor remediation timelines and declined after Quest’s October 2025 security updates.” the report states. “Despite limited forensic evidence, the available data supports a moderate-confidence assessment that Volt Typhoon exploited a zero-day vulnerability.” The actor stayed on the KACE server and used its admin features to take credentials. Victims include telecoms, government agencies, defense contractors, satellite and emergency communications, universities with ROTC programs, managed service and IT firms, and critical infrastructure such as water, energy, transportation, maritime, rail and aviation. What they share is access to bigger networks or customers. Hawaii, California and Texas were the top locations for several years. Lumen can’t say why, but the pattern fits pre-positioning for a crisis in the Indo-Pacific. “For enterprise leaders, the lesson is clear: systems with broad administrative reach can become high-value gateways to the entire organization and its customers. Reducing internet exposure, accelerating patching, strengthening access controls and preserving security telemetry are essential to detecting threats earlier and limiting their impact.” Lumen concludes.

ENGIE says attackers accessed French customers’ contact and energy contract data through a partner sales tool. Banking data was not affected. French multinational energy company ENGIE warned customers in France that attackers accessed personal information through a sales tool used by some business partners. The exposed data includes contact details and energy contract information that could help fraudsters impersonate the supplier. The company says its internal IT systems weren’t compromised and banking information wasn’t affected. It has blocked the attackers’ access, notified the relevant authorities and contacted affected customers, according to a spokesperson who spoke to BleepingComputer. According to notification emails sent to affected customers, the incident involved a tool used by partners to sell the company’s electricity and natural gas offers. The notification confirms that attackers gained unauthorized access to personal information stored in the sales tool. “We are informing you that an act of cyber-malice recently affected a tool used by some of our partners to market energy offers. As part of this incident, unauthorized access to your personal data was identified.” reads the notification. The compromised information includes customers’ names, postal addresses, email addresses, telephone numbers, customer IDs, contract numbers and energy supply identifiers. The company hasn’t disclosed the partner or platform involved. It also hasn’t revealed how many customers were affected, when the intrusion began, or when it was discovered. For electricity customers, these include the delivery point identifier (PDL). For gas customers, they include the metering and estimation point (PCE). ENGIE says financial information wasn’t affected and that its investigation indicates the exposure was limited to contact details and certain contract information. That reduces one category of risk but doesn’t eliminate financial fraud. Attackers can use accurate customer information to persuade victims to disclose additional data or make payments. Anyway, the exposed data could support impersonation scams. The company warned customers to watch for attempts to obtain further information or induce payments. A contract number, however, doesn’t prove that a caller is legitimate. It may simply show that the person has access to an exposed record. Customers should verify unexpected requests through trusted channels, even when the sender knows their personal details. ENGIE hasn’t attributed the attack to a specific group, and at this time no ransomware group has claimed responsibility for the attack. Experts recommend visiting ENGIE’s official website or app directly instead of signing in through links received by email. Customers should also be cautious with unexpected calls and messages. If someone requests a payment, password or additional personal information, they should end the exchange and verify the request using independently obtained official contact details. Customers should never share SMS verification codes, passwords or banking details with someone who contacts them unexpectedly.

The FBI seized Virtualine, a hosting service accused of supporting criminal sites, ignoring abuse reports and helping launder money from illegal activities The FBI seized the website of Virtualine, a hosting service that sold its services to criminals. The seized domain is virtualine.net, and the government says the site was used to commit and facilitate prolific criminal activity. That includes the advertisement of sexually explicit images of minors, the intentional disclosure of nonconsensual intimate images of adults and minors, and international money laundering. A court authorized the seizure. “Theophani K. Stamos, First Assistant U.S. Attorney for the Eastern District of Virginia, and Darren B. Cox, Assistant Director in Charge of the FBI Washington Field Office, announced today the seizure of the website virtualine.net after it was used to commit and facilitate prolific criminal activity, including the advertisement of sexually explicit images of minors, the intentional disclosure of nonconsensual intimate visual depictions of adults and minors, and international money laundering designed to conceal and promote criminal conduct.” The Justice Department has the details in a press release. Virtualine, also known as Secury, Massgod, Spamhouse, Lanedo and Omegatech, offers “bulletproof” hosting. It sells hosting, servers and domain names to customers who want a provider that ignores abuse complaints. It promotes its services on cybercrime forums. Court records include examples of those ads. In September 2024, Virtualine told an Exploit.in user that it allowed illegal activities such as phishing, payment card fraud, email spam and port scanning, but banned child sexual abuse material and terrorism-related content. In June 2025, it boasted on HackForums that it ignored more abuse than three therapists combined. In March 2026, Virtualine promoted an “additional protection plan” for customers, offered after the company received an official request from law enforcement. Under the plan, it would move the customer’s criminal infrastructure to another shell company unaffiliated with Virtualine, and then reactivate the server. It was a game of musical shell companies. “In March 2026, Virtualine advertised its “additional protection plan,” which it offered to its customers after “receiv[ing] an official request from law enforcement agencies.” Under this plan, Virtualine would move the customer’s criminal infrastructure to “another shell company not affiliated with Virtualine, after which the server is reactivated.”” continues the press release.”As Virtualine advertised to users on the platform HackForums in June 2025, “Virtualine ignored more abuse than your last three therapists.”” Despite saying it bans child content, the government says Virtualine knowingly hosted a website that carried it. Court records call that site Vendor 1. It’s a criminal online forum where users post and sell access to nude, sexually suggestive or sexually explicit images and videos of minors and adults, and it also promotes a hack-for-hire service in which people pay hackers to get into victims’ online accounts without consent and take explicit images and videos. In January 2026, about a month after assigning Vendor 1 an IP address, Virtualine began receiving reports of child sexual abuse images and videos on the server. The reports came from police in Germany, Canada and Australia, the US National Center for Missing and Exploited Children (NCMEC), and a victim’s lawyer. According to the government, Virtualine continued hosting Vendor 1 despite those warnings. The government also says Virtualine helped Vendor 1 build a new website. It allowed users to upload illegal material and download it after paying. The site accepted several payment methods, including an option called “BTC [NO-AML].” It used bitcoin addresses outside a hosted payment service, allowing customers to pay directly and avoid that service’s checks for illegal funds. Authorities say some payments came directly from criminal groups. They accuse Virtualine of accepting the money and moving it through further transactions to hide its source. The FBI’s Washington Field Office led the investigation, with significant help from Germany’s Polizei Hessen, the Netherlands’ Politie Midden-Nederland, the U.K.’s National Crime Agency, and private partners OverRIPE and Lumen. The Justice Department’s Office of International Affairs also assisted. Assistant U.S. Attorneys Laura D. Withers and Stefanie A. Schwartz represent the government. A domain seizure doesn’t end the problem, and the government says so in plain terms. The new website Virtualine built with Vendor 1 has already drawn at least one abuse complaint about sexually explicit images of children, and the release adds: Virtualine hosts this new website to this day.
