NSA, FBI, and CISA have a cybersecurity Information sheet on deepfake threats you may find interesting or our article on risk of non-human entities.
In today’s digital landscape, non-human identities (NHIs) have become an integral part of modern enterprise operations. From APIs and bots to service accounts and IoT devices, these digital entities are revolutionizing how businesses function. However, with this technological advancement comes a new set of cybersecurity risks that organizations must address.
The Staggering Scale of Non-Human Identities
Recent research reveals a startling statistic: non-human identities now outnumber human users by a ratio of 45 to 1 in many IT ecosystems. This exponential growth has created a vast and often overlooked attack surface for cybercriminals to exploit.
Top Threats to Non-Human Identities
The OWASP Top 10 Non-Human Identities Risks for 2025 provides a comprehensive overview of the most critical security risks associated with NHIs. Let’s examine some of these threats and compare them with other industry findings:
1. Improper Offboarding
OWASP highlights the risk of inadequately deactivating or removing NHIs when they’re no longer needed. This aligns with industry observations about the challenges of managing the lifecycle of non-human identities. Many organizations struggle with tracking and decommissioning unused service accounts, leaving potential backdoors for attackers.
2. Secret Leakage
The exposure of sensitive credentials like API keys and tokens is a significant concern. This risk is echoed in other sources, which emphasize the dangers of storing secrets in plaintext or hardcoding them into source code. Such practices can lead to unauthorized access and data breaches.
3. Overprivileged NHIs
OWASP warns against assigning excessive privileges to NHIs. This issue is widely recognized in the industry, with experts stressing the importance of implementing the principle of least privilege. Overprivileged identities, if compromised, can give attackers broad access to critical systems.
Mitigation Strategies for Businesses
To address these threats, organizations should consider the following steps:
Implement Robust Lifecycle Management: Automate the provisioning, rotation, and de-provisioning of NHI credentials. This helps ensure that unused or outdated identities are promptly removed, reducing the attack surface.
Enforce the Principle of Least Privilege: Grant NHIs only the minimum permissions necessary for their specific functions. Regularly review and adjust access rights to maintain a strong security posture.
Continuous Monitoring and Auditing: Implement systems for real-time monitoring of NHI activities. This allows for quick detection of anomalies and potential security breaches.
Secure Secrets Management: Utilize dedicated secrets management solutions to store and protect sensitive credentials. Avoid hardcoding secrets in source code or storing them in plain text.
Regular Security Assessments: Conduct periodic audits of your NHI landscape to identify and address potential vulnerabilities.
The Human Element in Managing Digital Identities
While technological solutions are crucial, it’s important to remember the human aspect of managing NHIs. As Mitch Greenfield from Humana points out, “The complexity grows as you manage thousands of applications and more than 100,000 entities. Without proper integration and governance, the risks multiply”.
This highlights the need for a cultural shift within organizations. Businesses must treat non-human identities with the same level of attention and security as human ones. It’s not just about implementing tools; it’s about fostering a security-conscious mindset across all levels of the organization.
Conclusion: A Call to Action
As we navigate the evolving landscape of digital identities, the management of NHIs has become a critical component of cybersecurity strategy. The risks are real and growing, but so are the solutions available to mitigate them.
By taking proactive steps to secure non-human identities, businesses can turn what could be a vulnerability into a strength. As Parham Eftekhari of CyberRisk Alliance reminds us, “Every unmanaged or under-secured identity is a potential breach waiting to happen”. The time to act is now – before these silent threats become tomorrow’s headlines.

Free speech on social media platforms has become a contentious issue, with concerns about content moderation, misinformation, and the balance between protecting expression and preventing harm. Recent developments have highlighted the challenges in this area:
Free Speech Concerns
Social media platforms face a complex balancing act when it comes to content moderation and free speech:
As private companies, platforms like Facebook and Twitter are not bound by First Amendment restrictions and can moderate content as they see fit.
However, their significant role in public discourse has led to calls for them to preserve robust debate and err on the side of preserving speech.
Government attempts to regulate how platforms moderate content have faced legal challenges on First Amendment grounds.
There are concerns that overly aggressive moderation could infringe on users’ ability to express themselves freely online.
Third-Party Fact-Checking
Many platforms have relied on partnerships with independent fact-checkers to combat misinformation:
Meta (Facebook) has used a third-party fact-checking program since 2016 to evaluate potentially false or misleading content.
Fact-checks by third parties were found to be perceived as more effective than other approaches like algorithmic labels.
Studies have shown fact-checking can be effective at reducing false beliefs across different countries.
However, there are some drawbacks:
Fact-checking programs have faced accusations of political bias.
The process can be slow compared to the rapid spread of misinformation.
There are concerns about scalability given the volume of content on social media.
Community Notes Approach
Some platforms are shifting towards a community-driven fact-checking model:
X (formerly Twitter) pioneered the “Community Notes” system, which allows users to add context to potentially misleading posts.
Meta recently announced plans to replace its third-party fact-checking program with a Community Notes-style system in the US.
Potential benefits of Community Notes include:
Improved scalability by leveraging users to identify and contextualize misinformation.
Increased trust, as some studies found community notes were perceived as more trustworthy than simple misinformation flags.
Empowering users to provide context rather than relying solely on removals or labels.
However, the effectiveness of Community Notes is still being evaluated:
Early studies on X’s system found mixed results, with some showing high accuracy of notes but limited impact on election misinformation.
There are concerns about whether a diverse enough group of users will participate to ensure balanced fact-checking.
Balancing Free Speech and Misinformation
The shift towards community-driven approaches reflects ongoing attempts to balance free speech concerns with efforts to combat misinformation:
Community Notes aim to provide context rather than removing content, potentially addressing censorship concerns.
However, there are worries that moving away from expert fact-checkers could make it harder for users to find trustworthy information.
The effectiveness of community-driven approaches in reducing the spread and impact of misinformation remains to be seen.
As social media platforms continue to grapple with these issues, finding the right approach to content moderation and fact-checking while preserving free expression remains an ongoing challenge. The move towards community-driven systems represents an attempt to strike this balance, but their long-term impact on both free speech and misinformation is still uncertain.

In the ever-changing landscape of digital threats, cybersecurity has come a long way from its humble beginnings. Let’s journey through time and explore how cybersecurity has evolved from simple firewalls to sophisticated AI-powered defense systems.
The Early Days: Firewalls as the First Line of Defense
Remember when firewalls were all the rage? In the 1980s and 1990s, these digital gatekeepers were our primary defense against cyber threats. Firewalls acted like bouncers at a club, deciding which data packets could enter or leave a network. While they were adequate for their time, they were also relatively simple and static in their approach.
The Rise of Intrusion Detection and Prevention Systems
As cyber threats became more sophisticated, so did our defenses. Enter Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS). These technologies marked a significant step forward, actively monitoring network traffic for suspicious activities and potential security breaches.
Antivirus Software: The Personal Guardian
While network-level protection was evolving, personal computers needed their own defenders. Antivirus software emerged as the go-to solution for protecting individual devices from malware, viruses, and other digital nasties. As threats multiplied, antivirus programs had to constantly update their databases to keep up.
The Cloud Era: New Challenges, New Solutions
With the advent of cloud computing, the cybersecurity landscape shifted dramatically. Traditional perimeter-based security models were no longer sufficient. This led to the development of cloud-native security solutions and the concept of “zero trust” architecture, where trust is never assumed and verification is always required.
The Age of Big Data and Machine Learning
As the volume of data and the complexity of cyber threats grew exponentially, traditional rule-based systems struggled to keep up. Enter machine learning and big data analytics. These technologies allowed cybersecurity systems to process vast amounts of data, identify patterns, and detect anomalies that might indicate a security threat.
AI-Powered Defense Systems: The New Frontier
Today, we’re witnessing the rise of AI-powered defense systems, representing the cutting edge of cybersecurity technology. These systems go beyond simple pattern recognition, employing advanced algorithms to:
Predict and prevent potential threats before they occur
Adapt to new types of attacks in real-time

AI-powered systems have shown impressive capabilities, with some methods achieving detection rates as high as 95%.
The Human Element: Still Crucial
Despite these technological advancements, it’s important to remember that the human element remains crucial in cybersecurity. AI and machine learning are powerful tools, but they still require human oversight, interpretation, and decision-making to be truly effective.
Looking to the Future
As we look ahead, the future of cybersecurity is likely to involve even greater integration of AI and machine learning. We can expect to see more sophisticated predictive capabilities, enhanced automation, and perhaps even the use of quantum computing in cybersecurity.
The evolution of cybersecurity from firewalls to AI-powered defense systems is a testament to human ingenuity in the face of ever-evolving digital threats. As cyber attackers become more sophisticated, so too do our defenses. It’s an ongoing arms race, but one that’s crucial for protecting our digital lives and assets.
Remember, while technology advances, the best defense is still a combination of cutting-edge systems and cyber-aware humans. Stay informed, stay vigilant, and let’s keep our digital world secure together!
In recent years, Mac users have increasingly become targets for cybercriminals. The perception that MacOS is inherently secure has led to a false sense of security among users, making them prime targets for sophisticated malware attacks. One such threat is the Cthulhu Stealer malware, part of a growing trend of info stealers targeting macOS devices.
Understanding Cthulhu Stealer
Cthulhu Stealer is malware that sneaks into macOS systems to steal sensitive info. It’s part of a growing threat group called infostealers. These threats have become more common in 2023. Other threats include MacStealer, Pureland, Atomic Stealer, and RealStealer.
These threats often pretend to be real apps or files. They might be disguised as business documents or software updates. When a user opens these files, the malware starts its harmful work.
Cthulhu Stealer is a malware-as-a-service (MaaS) for macOS users. This means cybercriminals can rent it for a monthly fee. This makes it easy for anyone to use without needing tech skills. Cthulhu Stealer was available for $500 a month, showing how easy it is for attackers to use.
Malware-as-a-Service (MaaS) Model
The MaaS model is popular among cybercriminals because it’s easy to use. It lets attackers focus on spreading malware and getting data without knowing how it works. This model also helps malware developers keep their products up-to-date and appealing.
Cthulhu Stealer pretends to be an app like CleanMyMac, Grand Theft Auto IV, and Adobe GenP. It asks for sensitive information like passwords and MetaMask credentials and sends it to a server controlled by the attackers. Malware can steal many data types, including cryptocurrency wallets and browser cookies.
How Threat Actors Target Mac Users
Cybercriminals use different ways to get malware to Mac users:
1. Social Engineering: They might pretend to be potential clients or partners. They send emails with fake attachments that look like business documents. This trick works well on business users who don’t suspect anything.
2. Malvertising: Fake ads can lead users to dangerous websites. These ads often pop up on real websites, making users download malware.
3. Free Content Lures: Many download free software or media, not knowing it might be malware. Fake apps or media can hide malware.
4. Cryptocurrency Targeting: Some malware targets cryptocurrency users, trying to steal wallet information and other financial details.
Reasons for Targeting Mac Users
There are several reasons why Mac users are targeted:
1. Security Perception: Many Mac users believe MacOS is more secure than competing operating systems like Windows. Apple’s marketing partly influences this belief and that there have historically been fewer virus instances on MacOS than on other platforms. Because of this, Mac users can be less security-aware, which makes them appealing targets for fraudsters.
2. Expanding Market Share: MacOS has been gaining ground on the latter despite being less popular than Windows. This expansion allows threat actors to take advantage of a less crowded industry. The number of potential victims increases with Mac users, making it profitable for hackers to create and distribute malware tailored to the operating system.
3. Vulnerabilities: Compared to the previous year, there was a notable increase in the number of macOS vulnerabilities exploited in 2023—more than 30% more. This increase implies that, even though the number of vulnerabilities has decreased, attackers are still discovering and taking advantage of more macOS flaws. This pattern suggests that macOS has become more appealing as a target for malicious activity.
4. Lucrative Targets: Professionals and business people are frequent Mac users whose devices may contain significant data. This includes wallets for cryptocurrencies, bank information, and sensitive company information—all fascinating to hackers. Since info stealers like Cthulhu Stealer are built to retrieve this information, they are a well-liked option for targeting Mac users.
5. Lack of Competition: There is a lot of malware on the Windows market, which makes it difficult for new threat actors to get traction. On the other hand, there is less competition in the macOS market, which presents a chance for cybercriminals to take advantage of this and create a presence in a rapidly expanding sector.
6. Complex Attack Vectors: Malicious actors utilize sophisticated methods to infect Mac users with malware. These include free content lures, which take advantage of people’s demand for free software and media downloads, and malvertising tactics, which utilize deceptive adverts to send visitors to harmful websites. These techniques successfully elude established security protocols and deceive people into downloading malicious software.
Protecting Against Mac Malware
Mac users need a robust security plan to protect them from threats like Cthulhu Stealer. Here are some steps to follow:
1. Enable the Firewall: Turn on your Mac’s firewall to block unwanted access. Go to System Preferences > Security & Privacy > Firewall and toggle it on. This keeps your device safe from malicious traffic.
2. Enable Security Features: Use macOS’s built-in security tools, such as Gatekeeper, XProtect, and FileVault. Also, consider getting a third-party antivirus for extra protection.
3. Manage App Permissions: Control which apps can access your data and system features. Go to System Preferences > Security & Privacy > Privacy to check and adjust app permissions. This helps stop malware from getting too much access.
4. Secure Your Network: Use a Virtual Private Network (VPN) to encrypt your internet, especially on public Wi-Fi. This keeps your data safe from hackers.
5. Be Wary of Unsolicited Communications: Don’t open emails from unknown senders, especially those with attachments or links. Always check the sender’s identity before opening anything.
6. Avoid Free and Untrusted Downloads: Don’t download software from shady places. Always get apps from trusted sources like the Mac App Store.
7. Use Ad Blockers and Web Filters: These tools can block malvertising and other online dangers.
