Смысл: The text poses a theoretical cybersecurity challenge: how to transmit data over a monitored network such that the transmission is undetectable and unprovable even if the binary is analyzed. It simultaneously serves as a memorial to the influential reverse engineer ms-rem.
A request for the community to solve a theoretical challenge by ms-rem on how to make network data transmission unprovable even with full traffic logs and source code access.
Смысл: The text introduces a technical analysis of a malware sample linked to a 2012 Java exploit, reflecting the author's expertise in reverse engineering and cybersecurity.
A security researcher introduces their rapid analysis of a new malware sample associated with a legacy 2012 Java vulnerability.
Смысл: The text uses the plot of the anime 'Death Note' to explain the principles of information theory and deanonymization. It argues that Light Yagami's downfall was not due to L's genius alone, but due to a series of avoidable 'information leaks' (patterns) that systematically reduced his anonymity from 33 bits to nearly zero.
An analysis of 'Death Note' through the lens of information theory, demonstrating how Light Yagami's behavioral patterns led to his deanonymization.
Смысл: The main idea is that mosaic blurring of text and numbers is mathematically reversible through a brute-force dictionary attack, making it an unsafe method for protecting sensitive data. The author advocates for complete redaction (painting over) as the only secure alternative.
Mosaic blurring of sensitive numbers is insecure because it can be reversed using a dictionary attack; always paint over confidential data instead.
Смысл: The text describes the technical reversal of intentional data obfuscation implemented by the Russian CEC to prevent the automated collection and analysis of election results, providing a tool to ensure data transparency.
An engineer developed and shared a tool to decode obfuscated 2021 Russian election data from the CEC website, bypassing various CSS, JS, and font-level tricks.
