Hackers Exploit AnyDesk Vulnerability to Gain Admin Access – PoC Released

A newly discovered vulnerability in AnyDesk, the popular remote desktop software, has sparked serious cybersecurity concerns.

Identified as CVE-2024-12754 and tracked under ZDI-24-1711, this flaw allows local attackers to exploit a mechanism to handle Windows background images, potentially escalating their privileges to administrative levels.

Researchers warn that this vulnerability poses a significant risk to sensitive system files, with the Proof-of-Concept (PoC) exploit now publicly available.

Details of the Vulnerability

The vulnerability has been categorized under CWE-59 (Path Traversal) with a CVSS score of 5.5 (Medium), indicating its potential to compromise system confidentiality.

As per a report by Cyber Security News, Cybersecurity researcher Naor Hodorov discovered that the issue resides in AnyDesk’s process of copying desktop background images during session initiation.

AnyDesk copies the current desktop background image to the C:\Windows\Temp\ directory when initiating a session.

This operation is executed by the AnyDesk service under the NT AUTHORITY\SYSTEM account, which holds high-level privileges.

How Attackers Exploit It

The flaw enables a low-privileged local user to manipulate this file-copying process to perform arbitrary file read or copy operations, as reported by Github. Here’s how the attack unfolds:

File Permissions and Ownership:

When AnyDesk copies the background image, the resulting file inherits ownership and permissions from the SYSTEM account.

By default, low-privileged users do not have access to files created in C:\Windows\Temp\, as these files are protected by the SYSTEM account.

AnyDesk copy the existing background image
AnyDesk copy the existing background image

File Name Pre-Creation:

An attacker can pre-create a file in the C:\Windows\Temp\ directory with the same name as the background image file.

Once the vulnerability is triggered, AnyDesk overwrites this file with data from the source image, but the file retains its original ownership and permissions.

File Copy performed by AnyDesk

Directory Junction Attack:

By creating a symbolic link (junction) pointing to sensitive system directories, such as \Device\HarddiskVolumeShadowCopy1\Windows\System32\CONFIG, attackers can redirect AnyDesk’s file-copying operation to access protected files like the SAM (Security Account Manager), SYSTEM, and SECURITY files.

Access Denied
Access Denied

These files are critical for the Windows authentication system.

Privilege Escalation: With access to these files, attackers can extract hashed credentials and machine keys to obtain administrative privileges, enabling full system compromise.

While exploitation requires local access and low-level privileges, the vulnerability’s implications are severe.

Attackers can use the exploit to steal credentials, gain unauthorized access to sensitive data, and even take full control of the affected system.

To mitigate this threat, AnyDesk has released version 9.0.1, which includes patches to address the vulnerability. Users and organizations are strongly advised to update to this version immediately.

The discovery of CVE-2024-12754 underscores the growing sophistication of local privilege escalation techniques. What may seem like a benign feature, such as handling desktop background images, can be exploited in creative and high-impact ways.

This reminds organizations and developers to scrutinize even the most seemingly innocuous application processes for security flaws.

While AnyDesk’s patches effectively address this issue, users must remain proactive in applying updates and adopting robust security measures.

The release of the PoC highlights the urgency of taking immediate action to protect against potential exploitation. Cybersecurity vigilance remains a necessity in the face of evolving threats.

UK Pressures Apple to Create Global Backdoor To Spy on Encrypted iCloud Access

United Kingdom has reportedly ordered Apple to create a backdoor allowing access to all encrypted content stored in its iCloud service.

The demand, issued under the U.K.’s controversial Investigatory Powers Act of 2016, has raised alarm among privacy advocates and tech experts.

If implemented, this order would allow British authorities to bypass encryption protections not only for U.K. users but also for Apple customers worldwide.

The Home Office said Thursday that its policy was not to discuss any technical demands.

“We do not comment on operational matters, including for example confirming or denying the existence of any such notices,” a spokesman said.

Unprecedented Scope of Access

Unlike previous government requests targeting specific accounts, the U.K.’s order seeks blanket access to fully encrypted material.

This approach is unprecedented among major democracies and could set a global precedent for undermining encryption.

Experts warn that such a demand could weaken user trust in technology companies and expose sensitive data to potential misuse.

Apple, which has long positioned itself as a champion of user privacy, is reportedly considering withdrawing its encrypted storage services from the U.K. rather than compromising its security promises globally.

However, this move would not satisfy the U.K.’s demand for access to encrypted data stored in other countries, including the United States.

The order was delivered through a “technical capability notice,” a legal instrument under the Investigatory Powers Act often criticized as the “Snoopers’ Charter.”

“The British government’s undisclosed order, issued last month, requires blanket capability to view fully encrypted material, not merely assistance in cracking a specific account, and has no known precedent in major democracies.” Washington Post reported.

The law allows the government to compel companies to assist in surveillance efforts while prohibiting them from disclosing such demands.

 “The person deemed it shocking that the U.K. government was demanding Apple’s help to spy on non-British users without their governments’ knowledge”

Apple can appeal the notice to a secret technical panel and a judge, but it must comply with the order during the appeal process.

In March 2022, Apple had warned Parliament about the potential global ramifications of such demands.

It argued that forcing companies to weaken encryption could violate international privacy laws, including rulings by the European Court of Human Rights.

Global Reactions and Concerns

The U.K.’s move has drawn sharp criticism from privacy advocates and technologists worldwide.

If the UK gains access to encrypted data, other countries like China, which have allowed encrypted storage, might demand the same backdoor access. This could push Apple to shut down the service altogether rather than comply.

Meredith Whittaker, president of encrypted messaging service Signal, described it as “a shocking move” that could position the U.K. as a “tech pariah.”

U.S. Senator Ron Wyden called on American officials to dissuade Britain from enforcing such measures, warning of disastrous consequences for privacy and national security.

Critics argue that backdoors intended for law enforcement can be exploited by criminals and authoritarian regimes.

They also highlight the potential ripple effect: if the U.K. secures access to encrypted data, other countries like China may demand similar concessions from tech companies.

Apple’s Advanced Data Protection feature, introduced in 2022, offers end-to-end encryption for iCloud storage a level of security that even Apple cannot bypass.

While most users do not enable this feature, it provides enhanced protection against hacking and unauthorized access. Apple has resisted similar demands in the past, including objections from the FBI during Donald Trump’s presidency.

Other tech giants like Google and Meta have also implemented strong encryption measures but have so far avoided similar legal confrontations.

Google stated that it has not been able to access Android backups due to default encryption since 2018, while Meta has maintained that it will not weaken its encryption architecture for government requests.

The battle over encryption highlights a growing tension between governments’ desire for surveillance capabilities and individuals’ right to privacy.

Law enforcement agencies argue that encryption hampers their ability to investigate serious crimes like terrorism and child exploitation. However, privacy advocates counter that weakening encryption creates vulnerabilities that jeopardize cybersecurity on a global scale.

As this debate unfolds, Apple’s response to the U.K.’s demands could set a critical precedent for how tech companies navigate government pressure while upholding user privacy.

The outcome may also influence international norms around encryption and digital rights in an increasingly interconnected world.

Autonomous LLMs

Large Language Models (LLMs) are transforming penetration testing (pen testing), leveraging their advanced reasoning and automation capabilities to simulate sophisticated cyberattacks.

Recent research demonstrates how autonomous LLM-driven systems can effectively perform assumed breach simulations in enterprise environments, particularly targeting Microsoft Active Directory (AD) networks.

These advancements mark a significant departure from traditional pen testing methods, offering cost-effective solutions for organizations with limited resources.

A study conducted using a prototype LLM-based system showcased its ability to compromise user accounts within realistic AD testbeds.

The system automated various stages of the penetration testing lifecycle, including reconnaissance, credential access, and lateral movement.

By employing frameworks like MITRE ATT&CK, the LLM-driven system demonstrated proficiency in identifying vulnerabilities and executing multi-step attack chains with minimal human intervention.

This approach not only enhances efficiency but also democratizes access to advanced cybersecurity tools for small and medium enterprises (SMEs) and non-profits.

Real-World Applications and Challenges

The prototype system was tested in a simulated AD environment called “Game of Active Directory” (GOAD), which replicates the complexity of real-world enterprise networks.

The LLM autonomously executed attacks such as AS-REP roasting, password spraying, and Kerberoasting to gain unauthorized access to user accounts.

It also utilized tools like nmap for network scanning and hashcat for password cracking, showcasing its ability to adapt to dynamic scenarios.

Despite its successes, the system faced challenges. Approximately 35.9% of generated commands were invalid due to tool-specific syntax errors or incomplete context provided by the planning module.

However, the system exhibited robust self-correction mechanisms, often recovering from errors by generating alternative commands or reconfiguring its approach.

This adaptability underscores the potential of LLMs to emulate human-like problem-solving in cybersecurity operations.

Implications for Cybersecurity

According to the research, the integration of LLMs into pen testing has profound implications for cybersecurity.

First, it reduces reliance on human expertise, addressing the shortage of skilled cybersecurity professionals.

Second, it lowers costs significantly; the average expense per compromised account during testing was approximately $17.47—far less than hiring professional penetration testers.

Third, it enables continuous and adaptive security assessments, keeping pace with evolving threat landscapes.

However, the use of LLMs in cybersecurity is not without risks.

Their capability to automate complex attacks raises concerns about misuse by malicious actors.

Additionally, challenges such as tool compatibility, error handling, and context management need further refinement to maximize their effectiveness.

As LLMs continue to evolve, their role in cybersecurity will expand beyond offensive applications like pen testing to defensive measures such as threat detection and vulnerability management.

Organizations must adopt proactive strategies to harness these technologies responsibly while mitigating associated risks.

The future of pen testing lies in hybrid models that combine human expertise with LLM-driven automation.

By addressing current limitations and fostering ethical use, LLMs can revolutionize cybersecurity practices, making advanced security measures accessible to all organizations.

Backdoor Attacks

Semantic communication systems, powered by Generative AI (GAI), are transforming the way information is transmitted by focusing on the meaning of data rather than raw content.

Unlike traditional communication methods, these systems encode semantic features such as text, images, or speech into low-dimensional vectors, significantly reducing bandwidth usage while maintaining the integrity of transmitted information.

This innovation has found applications in data-intensive domains like augmented reality (AR), Internet of Things (IoT), and autonomous systems.

However, the reliance on deep learning models exposes semantic communication systems to backdoor attacks.

These attacks covertly embed malicious triggers into training datasets or models, causing systems to misinterpret poisoned inputs while leaving clean data unaffected.

For example, in autonomous driving scenarios, a backdoor attack could manipulate sensor data to misclassify a stop sign as a yield sign, posing significant safety risks.

The Threat of Backdoor Attacks

Backdoor attacks exploit the training phase by embedding hidden triggers in datasets or models.

These triggers are designed to activate specific malicious behaviors during inference without impacting normal operations on clean data.

Current defenses against such attacks often involve neuron pruning or reverse engineering but come with limitations.

Neuron pruning, for instance, can degrade the model’s performance on clean inputs, while other methods impose strict data format requirements that limit their applicability.

To address these shortcomings, researchers have introduced a novel defense mechanism leveraging semantic similarity analysis.

This approach detects poisoned samples by analyzing deviations in the semantic feature space without altering the model structure or imposing constraints on input formats.

A Novel Defense Framework

The proposed defense mechanism employs a threshold-based detection framework to identify poisoned samples effectively:

  1. Baseline Establishment: A clean dataset is used to compute baseline semantic vectors that represent expected patterns in semantic space.
  2. Threshold Determination: A similarity metric measures deviations between input samples and the baseline.
  3. Sample Classification: Samples exceeding the threshold are flagged as poisoned and excluded from further processing.

This framework ensures high detection accuracy and recall across varying poisoning ratios while preserving the model’s ability to process clean inputs effectively.

Extensive experiments were conducted using datasets like MNIST to evaluate the proposed defense mechanism under different poisoning ratios (5%-50%).

Results demonstrated that the mean-threshold strategy achieved perfect recall (100%) and high accuracy (96%-99%) across scenarios.

According to the report, the max-threshold approach also maintained high accuracy but showed slightly lower recall due to its stricter classification criteria.

Adjusting thresholds dynamically based on percentiles further optimized performance, achieving an ideal balance between recall and accuracy at specific settings.

This innovative defense mechanism represents a significant advancement in securing GAI-driven semantic communication systems against backdoor attacks.

By leveraging semantic similarity analysis, it ensures robust protection without compromising system performance or flexibility.

Future research will focus on extending this framework to handle more complex data types like audio and video while exploring adaptive threshold-setting methods to counter evolving attack strategies.

As semantic communication continues to shape next-generation networks, such advancements will be critical in ensuring their security and reliability.

Video Attachments

Cybercriminals are increasingly exploiting image and video files to deliver malware, leveraging advanced techniques like steganography and social engineering.

These methods allow attackers to embed malicious code within seemingly harmless multimedia files, bypassing traditional security measures and deceiving unsuspecting users.

Hackers have used image-based malware to distribute tools like VIP Keylogger and 0bj3ctivity Stealer, which steal sensitive data such as passwords, keystrokes, and screenshots.

These campaigns often begin with phishing emails disguised as legitimate invoices or purchase orders.

Once opened, these emails exploit vulnerabilities to download malicious images containing embedded malware.

The Evolution of Video-Based Malware Delivery

A new frontier in malware delivery involves video files. Dubbed “VidSpam,” this tactic uses lightweight video attachments in multimedia messages (MMS) to lure victims into scams.

Video Attachments
VidSpam Bitcoin message.

For example, attackers have been observed using 14KB .3gp video files that appear benign but redirect users to attacker-controlled platforms like WhatsApp groups.

Once there, scammers employ high-pressure tactics to extract money or personal information from victims.

These video-based attacks mark an evolution from static image abuse, adding credibility to malicious messages while evading detection by traditional content filters.

The small size and low resolution of these videos make them accessible across devices with limited storage or slower networks, further broadening the attack surface.

Steganography: The Hidden Danger in Multimedia

Steganography, a technique for concealing data within other files, has become a favored tool for embedding malware in images and videos.

By manipulating pixel data or metadata, attackers can hide malicious payloads without altering the file’s appearance.

When unsuspecting users open these files, the malware is executed, often bypassing antivirus software.

For example, attackers have used steganography to hide JavaScript code within images or videos that execute upon opening.

This method has been employed in campaigns targeting both individuals and organizations, with applications ranging from ransomware deployment to data exfiltration.

According to Proofpoint, the ubiquity of multimedia messaging makes it a prime target for cybercriminals.

New Scareware Attack Targeting Mobile Users to Deploy Malicious Antivirus Apps

By
Aman Mishra
-
Scareware

A new wave of scareware attacks has emerged, targeting unsuspecting mobile users with fake antivirus applications designed to exploit fear and trick victims into downloading malicious software.

Scareware, a type of digital fraud, employs social engineering tactics to alarm users with fabricated warnings about security threats, ultimately coercing them into taking risky actions.

Scareware: A Growing Threat in Cybersecurity

Scareware operates by generating alarming messages that mimic legitimate antivirus alerts or system notifications.

These messages often claim that the user’s device is infected with viruses or at risk of data loss.

The attackers rely on pop-up windows, banner ads, email notifications, and even simulated system errors to deliver these deceptive warnings.

Once the victim is sufficiently panicked, they are urged to install a specific application purportedly to resolve the issue, which is often malware disguised as antivirus software or system optimization tools.

The consequences of falling for these schemes can range from installing harmless but unnecessary software to more severe outcomes, such as downloading ransomware that encrypts files or spyware that compromises sensitive information like banking credentials.

In some cases, scareware campaigns have evolved into hybrid attacks, combining scare tactics with sextortion schemes.

For example, victims may receive an email claiming they were recorded in compromising situations and are directed to install a “special player” to view the footage, which is malware in disguise.

Mobile Devices: A New Frontier for Scareware

Recently, scareware campaigns have increasingly targeted mobile devices, exploiting users’ fears of hardware malfunctions.

One variant simulates a faulty smartphone display, complete with blinking effects and a warning message claiming the damage is caused by a virus.

According to Kaspersky, the attackers then prompt users to purchase and install a fake antivirus app to “fix” the issue.

Microsoft Sysinternals 0-Day Vulnerability Enables DLL Injection Attacks on Windows

A critical zero-day vulnerability has been discovered in Microsoft Sysinternals tools, posing a serious security threat to IT administrators and developers worldwide.

The vulnerability enables attackers to exploit DLL injection techniques to execute malicious code, putting systems at risk of compromise.

Despite being disclosed to Microsoft over 90 days ago, the issue remains unresolved, leaving users reliant on manual mitigations to safeguard their environments.

Microsoft Sysinternals is a widely used suite of tools designed for system analysis, troubleshooting, and malware investigation. 

Popular utilities, such as Process Explorer, Autoruns, and Bginfo, are integral to system administrators for monitoring processes, configurations, and services.

However, unlike many Windows components that receive regular updates through the Windows Update infrastructure, Sysinternals tools require manual updates.

This lack of integration creates a significant window of risk when vulnerabilities, such as this one, are discovered.

Details of the Vulnerability

According to the Cyber Security News report, the vulnerability arises from how Sysinternals tools handle dynamic-link library (DLL) file loading.

These tools prioritize untrusted paths—such as the current working directory (CWD) or network paths—over safe, system-designated directories.

This allows attackers to stage malicious DLLs in the same location as a legitimate Sysinternals executable.

How the Exploit Works:

  1. Crafting a Malicious DLL: An attacker creates a DLL (e.g., cryptbase.dll or TextShaping.dll) embedded with malicious payloads.
  2. File Placement: The DLL is placed alongside a legitimate Sysinternals executable (e.g., Bginfo.exe).
  3. Execution: When the targeted application is executed, it loads the malicious DLL instead of the trusted one.
  4. Result: The attacker’s code runs with the user’s system privileges, potentially leading to full system compromise.

Real-World Application: Bginfo Trojan Deployment

One of the most glaring examples of exploitation involves the Bginfo tool, used in enterprise environments to display desktop system information.

In a simulated scenario, an attacker places a malicious DLL on a shared network directory. During system startup, a script executes Bginfo.exe directly from the network path.

The tool, in turn, loads the malicious DLL instead of the legitimate one, enabling the proliferation of malware like Trojans or backdoors across multiple systems. A technical writeup by the researcher cautions:

“If the network path contains a prepared DLL, each client can be automatically compromised during the startup process.”

The vulnerability was responsibly disclosed to Microsoft on October 28, 2024, in line with industry best practices.

However, Microsoft classified the issue as a “defense-in-depth” enhancement, meaning it does not consider the vulnerability a critical flaw but rather an issue to be addressed via secure usage practices.

Microsoft’s stance emphasizes running Sysinternals tools from local directories rather than network locations.

The researcher, however, argues this approach overlooks real-world scenarios where tools are executed directly from shared directories. As of February 2025, the vulnerability remains unpatched, exposing organizations to significant risk.

Sysinternals tools are indispensable for IT administration and malware analysis, yet this vulnerability highlights their inherent risks.

While trusted for identifying malicious behavior on systems, these tools now face scrutiny for enabling DLL injection attacks themselves. Until Microsoft addresses the issue, users must remain vigilant and proactive in securing their environments.
