Using eSIMs on Devices with Only Physical SIM Slots: A 9eSIM Review

This blog post details using a 9eSIM SIM card to enable eSIM functionality on devices that only accept physical SIM cards, tested on Android and Linux. The author purchased a 9eSIM bundle including the SIM, smartcard reader, and adapter. Initial setup proved slightly tricky, requiring the SIM card to be used within its original packaging for proper reader connection. Adding, switching, and deleting eSIM profiles was straightforward using an Android app or the Linux command-line tool lpac (and its GUI, EasyLPAC). Tests were conducted with free test eSIM profiles and a paid LycaMobile eSIM, successfully achieving eSIM connectivity on a Debian Linux laptop.

Tattoos and Cancer Risk: A Twin Study Reveals Increased Hazard

A study using the Danish Twin Tattoo Cohort reveals a heightened risk of lymphoma and skin cancer among tattooed individuals compared to their non-tattooed counterparts. Employing both twin cohort and case-cotwin study designs, the research indicates a stronger association with larger tattoos. The researchers hypothesize that ink deposits may interact with surrounding tissue, triggering an immune response and increased cell proliferation, thus raising cancer risk. However, limitations include a lack of sun exposure data and detailed tattoo type classification. Further research is urged to clarify the etiological pathway of tattoo ink-induced carcinogenesis and inform public health policy.

Russian Threat Actors Exploit Microsoft Device Code Authentication in Widespread Attacks

Volexity has uncovered multiple Russian threat actors employing sophisticated social engineering and spear-phishing campaigns to compromise Microsoft 365 accounts via Device Code Authentication phishing. These attacks exploit the less-familiar Device Code Authentication workflow, making them difficult for users to recognize as phishing attempts. The campaigns, often politically themed (e.g., focusing on the US administration), impersonate individuals from organizations like the US Department of State and the Ukrainian Ministry of Defence, luring victims into fake Microsoft Teams meetings or application access. Volexity is tracking three threat actors, one potentially linked to CozyLarch (overlapping with DarkHalo, APT29). The effectiveness of this attack stems from exploiting users' unfamiliarity with device code authentication, bypassing traditional security measures. Volexity recommends organizations block device code authentication via conditional access policies and enhance user security awareness training.

Ken Thompson's Sneaky C Compiler Backdoor: A Reflection on Trust

2025-02-16

In his paper "Reflections on Trusting Trust," Ken Thompson, co-creator of UNIX, recounts a chilling tale of a self-replicating backdoor he inserted into the C compiler. This backdoor would automatically inject itself into the login program during compilation, granting him unauthorized access. The insidious part? Even removing the backdoor from the source code wouldn't stop the compiler from re-inserting it during compilation. This story serves as a stark reminder of the limitations of trusting software and the inherent difficulty in ensuring complete security, even with source code review.

Intensional Programming in Joy: Introspection with a Single Operator

2025-02-12

This article explores intensional programming in Joy, a stack-based functional programming language. Joy itself is extensional, lacking the ability to 'dissect' code blocks. The author proposes two intensional operators: 'map' and 'quota', proving their mutual expressibility. While behaviorally equivalent, intensional programs can distinguish a single operator from a subprogram with multiple commands. This opens avenues for exploring weaker notions of equivalence in intensional languages and demonstrates a robust approach to introducing intensionality in minimalist languages like Joy.

Reverse Engineering a Cheap Indoor Camera: Exploiting Tapo's Security Flaws

2025-09-16

The author bought a cheap Tapo indoor camera to monitor their dog, but this led to an unexpected journey of reverse engineering. To bypass the cumbersome setup process and forced subscription of the Tapo app, the author decompiled the APK, performed a man-in-the-middle (MITM) attack, and wrote cryptographic scripts. This revealed a critical vulnerability: a default password "TPL075526460603". A bash script was created for cloudless onboarding. The process uncovered security flaws in Tapo's firmware, such as inconsistent use of SHA-256 and MD5 encryption and a haphazard password synchronization mechanism. The author successfully configured the camera, only to discover their dog mostly slept.

Itch.io faced backlash after payment processors forced them to remove adult content. Many suggested Itch.io create its own payment system or use one that handles adult material. A seasoned SRE with a background in finance and tech debunks these easy solutions. The article details the immense challenges of building a payment processor: bank sponsorship, licensing, KYC/KYCC compliance, and substantial security and compliance costs. Even finding an adult-content-friendly processor (like CCBill) comes with exorbitant fees and risks. The core issue, however, is that any part of the payment chain can be influenced by political pressure or moral censorship. Switching processors won't solve Itch.io's fundamental problem.
