TikTok Is Harming Children at an Industrial Scale

Posted: 2025-04-17 13:39:28

The article "TikTok Is Harming Children at an Industrial Scale" argues that TikTok's algorithm, designed for maximum engagement, exposes children to a constant stream of harmful content including highly sexualized videos, dangerous trends, and misinformation. This constant exposure, combined with the app's addictive nature, negatively impacts children's mental and physical health, contributing to anxiety, depression, eating disorders, and sleep deprivation. The author contends that while all social media poses risks, TikTok's unique design and algorithmic amplification of harmful content makes it particularly detrimental to children's well-being, calling it a public health crisis demanding urgent action. The article emphasizes that TikTok's negative impact is widespread and systematic, affecting children on an "industrial scale," hence the title.

The article "TikTok Is Harming Children at an Industrial Scale" posits that TikTok, the immensely popular short-form video platform, presents a significant and multifaceted threat to the well-being of children. The author argues that the platform's algorithmic design, coupled with its pervasive nature and the inherent vulnerabilities of young users, creates a perfect storm of negative consequences.

The central argument revolves around the concept of "industrial-scale harm." This refers not just to the sheer number of children exposed to potentially harmful content, but also to the systematic and pervasive nature of the harm itself. The author meticulously outlines several key areas of concern.

Firstly, the article emphasizes the addictive nature of TikTok's algorithm. Designed to maximize engagement, this algorithm relentlessly feeds users a stream of curated content, often exploiting base desires and triggering dopamine releases in the brain.

One Bug Wasn't Enough: Escalating Twice Through SAP's Setuid Landscape

permalink

Posted: 2025-04-09 16:56:31

Researchers discovered a vulnerability chain in SAP systems allowing for privilege escalation. Initially, a missing authorization check in a specific diagnostic tool allowed an attacker with low privileges to execute operating system commands as the sapadm user. This wasn't sufficient for full control, so they then exploited a setuid binary, sapstartsrv, designed to switch users. By manipulating the binary's expected environment, they were able to execute commands as root, achieving complete system compromise. This highlights the danger of accumulated vulnerabilities, especially within complex systems employing setuid binaries, and underscores the need for thorough security assessments within SAP environments.

This blog post by Anvil Secure details a complex vulnerability discovery within SAP systems, highlighting how multiple seemingly minor flaws can be chained together to achieve significant privilege escalation. The researchers began with a relatively low-impact vulnerability, a path traversal issue in the SAP Start Service script (startsap). This script, often configured with setuid root permissions, allows users to start and stop SAP systems. The discovered path traversal allowed malicious actors to manipulate log file locations, enabling them to overwrite arbitrary files on the system, albeit with the startsap user's permissions. While this initial vulnerability provided some control, it didn't grant root access directly.

Recognizing that limited file overwrite capability could be a stepping stone, the researchers meticulously examined the SAP environment for other exploitable components. They discovered a custom SAP program, sapuxuserchk, also running with setuid root. This program, responsible for verifying user existence within the SAP system, suffered from two key weaknesses. First, it dynamically loaded shared libraries. Second, its search path for these libraries included a user-writable directory. By strategically utilizing the initial path traversal vulnerability in startsap, the researchers could plant a malicious shared library in the searchable path. When sapuxuserchk subsequently executed, it unknowingly loaded the malicious library, granting the attackers root access.

However, the researchers didn't stop there. They investigated further and uncovered yet another privilege escalation path stemming from the same initial path traversal flaw. This time, they targeted the sapcpe program, a central control interface within SAP systems, also frequently configured with setuid root privileges. This program featured a similar vulnerability to sapuxuserchk – a dynamic library loading mechanism susceptible to manipulation through a user-writable library path. By again leveraging the startsap path traversal, the researchers replaced a legitimate library used by sapcpe with their own malicious version, thus gaining a second independent route to root access.

The post underscores the importance of defense-in-depth strategies. While individual vulnerabilities might seem insignificant in isolation, their combined impact can be devastating. The researchers emphasize that the prevalence of setuid binaries within the SAP landscape, combined with insecure library loading practices, creates a fertile ground for privilege escalation exploits. The blog post concludes by emphasizing the need for robust security practices, including careful scrutiny of setuid programs, secure library loading configurations, and adherence to the principle of least privilege. It also subtly advocates for the importance of vulnerability research and responsible disclosure, enabling vendors like SAP to address these weaknesses and improve the security posture of their systems.

It serves as a roadmap for system administrators and security professionals seeking to enhance the security posture of their Linux systems by leveraging kernel-level defenses.

The map categorizes these defenses into several key domains, reflecting different layers and aspects of kernel security. These include:

Kernel Self-Protection: This area focuses on mechanisms that protect the kernel itself from exploitation. Techniques listed encompass Kernel Address Space Layout Randomization (KASLR), which randomizes the location of kernel code in memory, and Kernel Page Table Isolation (KPTI/KAISER), which isolates user-space and kernel-space page tables to mitigate Meltdown-type vulnerabilities. It also covers Supervisor Mode Access Prevention (SMAP) and Supervisor Mode Execution Protection (SMEP), which restrict access and execution from supervisor mode to user-space memory, preventing certain types of privilege escalation attacks.
Memory Management Hardening: This domain deals with securing the kernel's memory management subsystem. It includes strategies like restricting memory allocations with SLAB_FREELIST_HARDENED, enabling memory tagging extensions like ARM Memory Tagging Extension (MTE), and implementing hardened usercopy functions to prevent vulnerabilities arising from copying data between user and kernel space.
Capability-Based Security: This section outlines the use of Linux capabilities, which provide a finer-grained alternative to traditional root privileges, allowing processes to have specific privileges without granting full administrative access. This helps limit the potential damage from compromised processes.
Namespaces and Seccomp: These features isolate processes from each other and the system, limiting their access to resources and system calls. Namespaces create isolated environments for processes, while Seccomp allows restricting the system calls a process can make. This restricts the attack surface available to a malicious process.
Security Modules: The map covers various security modules like SELinux, AppArmor, and TOMOYO Linux, which provide mandatory access control (MAC) frameworks. These modules enforce predefined security policies, restricting access to resources based on labels and rules, even for privileged processes. This adds an additional layer of security beyond traditional discretionary access control.
Cryptographic API Hardening: This area addresses securing cryptographic operations within the kernel. It highlights the use of cryptographic agility, enabling constant-time cryptographic algorithms to prevent timing attacks, and using a hardware security module (HSM) to offload sensitive cryptographic operations to a dedicated secure device.
Auditing and Intrusion Detection: This category covers mechanisms to monitor kernel activity and detect suspicious events. It includes the use of the audit subsystem for logging security-relevant events, and integrating kernel instrumentation with intrusion detection systems.
Exploit Mitigation Techniques: The map lists various exploit mitigation methods, like stack canaries, which detect stack overflows, and Shadow Stacks, which protect return addresses from modification. These techniques make it more difficult for attackers to exploit vulnerabilities.

The Linux Kernel Defence Map provides a valuable overview, presenting these security hardening concepts in a structured and accessible format. It serves as a starting point for those looking to understand and implement kernel-level security measures, offering a broad perspective on the landscape of available techniques and guiding further research into specific areas of interest. However, it's crucial to note that security is a continuous process, and this map represents a snapshot of current best practices, not a complete or static solution. Continuous learning and adaptation are essential for maintaining a robust security posture.

Scott Galloway's "Addiction Economy" argues that major tech platforms, like Facebook, Instagram, TikTok, and YouTube, are deliberately engineered to be addictive. They exploit human vulnerabilities, using persuasive design and algorithms optimized for engagement, not well-being. This "attention arbitrage" model prioritizes maximizing user time and data collection, which are then monetized through targeted advertising. Galloway compares these platforms to cigarettes, highlighting their negative impact on mental health, productivity, and societal discourse, while also acknowledging their utility and the difficulty of regulation. He concludes that these companies have become too powerful and calls for greater awareness, stricter regulations, and individual responsibility in managing our relationship with these addictive technologies.

Professor Scott Galloway's essay, "Addiction Economy," posits a disconcerting correlation between the meteoric rise of prominent technology platforms and the exploitation of inherent human vulnerabilities, particularly those related to addiction. He argues that these companies, encompassing social media giants like Facebook and Instagram, streaming behemoths like Netflix, and e-commerce titans like Amazon, have meticulously crafted their products and services to capitalize on the neurochemical pathways associated with reward and compulsion. This, he contends, creates a cycle of dependency that keeps users perpetually engaged, often to the detriment of their overall well-being.

Galloway elaborates on this concept by drawing parallels between the addictive properties of these platforms and the well-established mechanisms of substance addiction. He emphasizes the role of intermittent reinforcement, a core principle in behavioral psychology, wherein unpredictable rewards are particularly potent in establishing and maintaining compulsive behaviors. This unpredictability, manifested in the form of notifications, likes, and algorithmically curated content feeds, fuels a constant desire for validation and novelty, thereby hooking users into a continuous loop of engagement. He further elucidates this point by highlighting the meticulously designed user interfaces, often employing bright colors, gamification elements, and infinite scroll features, which are specifically engineered to maximize engagement and minimize friction, making it effortlessly easy to remain immersed within these digital environments.

The essay further explores the societal ramifications of this pervasive "addiction economy," arguing that it contributes to a decline in genuine human connection, fosters a culture of comparison and inadequacy, and exacerbates existing societal anxieties. Galloway suggests that the constant bombardment of curated content, often showcasing idealized versions of reality, cultivates unrealistic expectations and contributes to feelings of envy and dissatisfaction. He also notes the potential for these platforms to be exploited for the dissemination of misinformation and the polarization of public discourse, further undermining social cohesion and democratic values. He paints a picture of a populace increasingly tethered to their devices, sacrificing real-world interactions and experiences for the fleeting gratification offered by these digital platforms.

Galloway concludes by acknowledging the inherent complexities of this issue, recognizing the undeniable benefits that these technologies offer in terms of connectivity and access to information. However, he stresses the urgent need for greater awareness regarding the potentially manipulative tactics employed by these companies and advocates for increased regulation and responsible design practices to mitigate the negative consequences of this pervasive addiction economy. He emphasizes the importance of reclaiming control over our digital consumption habits and cultivating a more mindful and balanced relationship with technology, urging individuals to actively prioritize real-world connections and pursuits over the alluring, yet often empty, promises of the digital realm.

A few commenters suggest potential solutions, including stricter regulations and encouraging digital minimalism. Some disagreement exists on whether the responsibility lies solely with the companies or also with the users' lack of self-control. A compelling comment thread explores the parallels between social media addiction and gambling addiction, referencing similar psychological mechanisms and profit motives. Another interesting discussion revolves around the difficulty in defining "addiction" in this context and whether the term is being overused.

The Hacker News post titled "Addiction Economy," linking to Scott Galloway's blog post of the same name, has generated several comments discussing the addictive nature of modern technology and social media platforms.

Several commenters agree with Galloway's central premise, noting their own experiences or observations of addictive behaviors related to technology. One commenter points out the "variable reward" system employed by these platforms, drawing a parallel to slot machines and highlighting the effectiveness of intermittent reinforcement in driving engagement. Another user emphasizes the deliberate design choices made by tech companies to maximize user "time on site," even if it comes at the expense of users' well-being. This aligns with Galloway's argument about the exploitation of human psychology for profit.

The discussion also touches upon the broader societal implications of this "addiction economy." One commenter expresses concern about the impact on productivity and focus, suggesting that constant notifications and the allure of social media contribute to a fragmented attention span. Another raises the issue of mental health, linking excessive social media use to anxiety and depression, and highlighting the potential for negative self-comparison fueled by curated online personas.

Some comments offer potential solutions or coping mechanisms. One user suggests employing website blockers and limiting screen time as a way to regain control over one's digital consumption. Another advocates for greater awareness of these manipulative design tactics, empowering individuals to make more informed choices about their technology use. The idea of digital minimalism is also mentioned, encouraging users to be more intentional about which platforms they engage with and for what purpose.

Not all commenters fully agree with Galloway's perspective. One commenter argues that personal responsibility plays a significant role, suggesting that individuals should be held accountable for their own technology usage habits. Another points out that while the comparison to addiction is valid in some cases, it might be an overgeneralization to apply it to all forms of technology engagement. This commenter suggests a distinction between habitual use and genuine addiction.

Finally, the discussion extends to the role of regulation and the potential for government intervention to curb the negative impacts of the "addiction economy." Some commenters express skepticism about the feasibility and effectiveness of such regulations, while others argue that stronger oversight is necessary to protect vulnerable users and promote healthier online environments.

Couriers mystified by the algorithms that control their jobs

Delivery drivers, particularly gig workers, are increasingly frustrated and stressed by opaque algorithms dictating their work lives. These algorithms control everything from job assignments and routes to performance metrics and pay, often leading to unpredictable earnings, long hours, and intense pressure. Drivers feel powerless against these systems, unable to understand how they work, challenge unfair decisions, or predict their income, creating a precarious and anxiety-ridden work environment despite the outward flexibility promised by the gig economy. They express a desire for more transparency and control over their working conditions.

The Guardian article, "It's a nightmare: Couriers mystified by the algorithms that control their jobs," published on January 21, 2025, delves into the increasingly prevalent yet opaque world of algorithmic management within the gig economy, specifically focusing on the experiences of delivery couriers. The piece paints a detailed picture of how these sophisticated algorithms, employed by companies like Amazon, Uber Eats, and Deliveroo, exert a profound influence over virtually every aspect of a courier's workday, often to the detriment of the workers themselves.

The article elaborates on how these algorithms dictate not only the assignment of delivery routes and schedules, but also performance metrics, pay rates, and even disciplinary actions. Couriers, often classified as independent contractors rather than employees, find themselves subject to the whims of these complex systems with limited transparency or recourse. They express a deep sense of frustration and powerlessness, feeling trapped within a digital panopticon where their every move is scrutinized and evaluated by an unseen, unyielding force.

The piece highlights the inherent lack of human interaction and support within this algorithmic management structure. Couriers often struggle to understand why certain decisions are made, as appeals and complaints are frequently handled by automated systems or outsourced customer service representatives with limited authority. This lack of human intervention exacerbates the feeling of dehumanization, making couriers feel like cogs in a vast, impersonal machine.

The article further explores the precarious nature of gig work under algorithmic control. The constant pressure to maintain high performance ratings, coupled with the unpredictable nature of algorithmic assignments and pay fluctuations, creates a highly stressful and insecure work environment. Couriers are compelled to accept challenging deliveries, often at low pay rates, out of fear of negatively impacting their ratings and potentially losing access to future work opportunities. This precariousness is further compounded by the absence of traditional employment benefits such as sick pay, holiday leave, and health insurance, leaving couriers vulnerable to financial hardship.

Furthermore, the article touches upon the potential for algorithmic bias and discrimination. The opaque nature of these algorithms makes it difficult to ascertain whether they are perpetuating existing societal inequalities. Concerns are raised about the possibility of algorithms unfairly penalizing certain demographics based on factors such as location, ethnicity, or even perceived performance based on biased data inputs. This lack of transparency raises fundamental questions about fairness and accountability within the algorithmically managed gig economy. In conclusion, the article presents a concerning portrait of the challenges faced by couriers operating within a system increasingly dominated by algorithms, emphasizing the need for greater transparency, accountability, and worker protections in this rapidly evolving sector.

Several point out the lack of transparency and recourse for workers when algorithms make mistakes, leading to unfair penalties or lost income. Some discuss the broader societal implications of this trend, comparing it to other forms of algorithmic control and expressing concerns about the erosion of worker rights. Others offer potential solutions, including unionization, worker cooperatives, and regulations requiring greater transparency and accountability from companies using these systems. A few commenters suggest that the issues described aren't solely due to algorithms, but rather reflect pre-existing problems in the gig economy exacerbated by technology. Finally, some question the article's framing, arguing that the algorithms aren't necessarily "mystifying" but rather deliberately opaque to benefit the companies.

The Hacker News post "Couriers mystified by the algorithms that control their jobs" has generated a substantial discussion with a variety of perspectives on the use of algorithms in gig work.

Several commenters focus on the lack of transparency and control these algorithms create for workers. One commenter points out the inherent conflict between optimizing for efficiency and providing predictable or fair working conditions for the couriers. They argue that the algorithms prioritize speed and cost reduction, often at the expense of the drivers' well-being and income stability. Another commenter draws parallels to other industries where automation and optimization have led to job displacement and worsening working conditions, expressing concern that this trend is spreading to gig work.

The issue of algorithmic bias is also raised. Commenters discuss how these algorithms may inadvertently discriminate against certain groups of workers, for example, by assigning them less desirable or lower-paying deliveries based on factors like location or demographics. The lack of transparency makes it difficult to identify and address such biases.

Some commenters discuss the broader implications of algorithmic management, highlighting the potential for exploitation and the erosion of worker rights. They argue that the opaque nature of these systems prevents workers from understanding how decisions are made, making it difficult to challenge unfair treatment or advocate for better conditions. The lack of accountability on the part of the companies using these algorithms is also a recurring theme.

A few commenters offer alternative perspectives. One suggests that the algorithms, while imperfect, might be an improvement over traditional dispatch systems, potentially offering more flexibility and autonomy. Another points out the challenges of managing a large workforce and argues that algorithms might be necessary for efficient logistics, though acknowledging the need for greater transparency and fairness.

The conversation also touches on the potential for collective action and regulation. Some commenters suggest that unionization or regulatory intervention might be necessary to protect workers' rights and ensure fair treatment in the gig economy. Others propose technical solutions, such as open-source algorithms or worker-owned platforms, as potential ways to address the issues raised.

Overall, the comments reflect a general concern about the growing influence of algorithms in the workplace and their potential negative impact on workers. The discussion highlights the need for greater transparency, accountability, and potentially regulatory oversight to ensure fair and ethical labor practices in the gig economy.
