Pirates of Charity: Exploring Donation-based Abuses in Social Media Platforms
No full textWith the widespread use of social media, organizations, and individuals use these platforms to raise funds and support causes. Unfortunately, this has led to the rise of scammers in soliciting fraudulent donations. In this study, we conduct a large-scale analysis of donation-based scams on social media platforms. More specifically, we studied profile creation and scam operation fraudulent donation solicitation on X, Instagram, Facebook, YouTube, and Telegram. By collecting data from 151,966 accounts and their 3,053,333 posts related to donations between March 2024 and May 2024, we identified 832 scammers using various techniques to deceive users into making fraudulent donations. Analyzing the fraud communication channels such as phone number, email, and external URL linked, we show that these scamming accounts perform various fraudulent donation schemes, including classic abuse such as fake fundraising website setup, crowdsourcing fundraising, and asking users to communicate via email, phone, and pay via various payment methods. Through collaboration with industry partners PayPal and cryptocurrency abuse database Chainabuse, we further validated the scams and measured the financial losses on these platforms. Our study highlights significant weaknesses in social media platforms’ ability to protect users from fraudulent donations. Additionally, we recommended social media platforms, and financial services for taking proactive steps to block these fraudulent activities. Our study provides a foundation for the security community and researchers to automate detecting and mitigating fraudulent donation solicitation on social media platforms
Exploring the Potential of LLMs for Code Deobfuscation
No full textCode obfuscation alters software code to conceal its logic while retaining functionality, aiding intellectual property protection but hindering security audits and malware analysis. To address this, automated deobfuscation techniques have been developed, though existing approaches remain constrained by limited scope and specificity. Motivated by these challenges, this paper explores a novel approach for code deobfuscation based on Large Language Models (LLMs). First, we investigate the general capabilities of LLMs in reducing code complexity by choosing five different source-to-source obfuscation methods. Despite challenges regarding semantical correctness, our findings indicate that LLMs can be very effective in this task. Building on this, we fine-tune two versatile models capable of simplifying code obfuscated through up to seven different chained obfuscation transformations while consistently outperforming deobfuscation based on compiler optimizations and general-purpose LLMs. Our best model demonstrates an average Halstead metric program length reduction of 89.21% for our most challenging scenario. Finally, we conduct a memorization test to assess if performance stems from memorized code rather than true deobfuscation capabilities, which our models pass
Identiteter och världsbild : "hårdkokt" skriftbruk i Thorsten Jonssons noveller
No full textidentity and worldview – “hard-boiled” writing in Thorsten Jonsson’s short storiesThis article deals with the Swedish author Thorsten Jonsson (1910–50) and his first short story collection Som det brukar vara (1939) [‘As it usually is’]. The nar- rative represents a new modernistic literary trend in Swedish prose in the 1930s. i take my starting point in Burgess & ivanič’s (2010) theories of the act of writing involving many different identities, and particularly what Burgess & ivanič iden- tify as the discursive self. By contemporary readers and critics the discursive self in the short story collection was often connected with an American hard-boiled literary ideal, often linked to ernest Hemingway’s writings. in this article i dis- cuss the common textual features of the two authors’ first collections, but also the differences that emerge when looking through the linguistic surface. The analysis shows that Thorsten Jonsson’s discursive self is based upon a northern Swedish culture, Hemingway’s on an urban American one. </p
Measures of excess liquidity
Get PDFThe aim of this note is to provide an overview of various measures of excess liquidity, which can be defined as the deviation of the actual stock of money from an estimated equilibrium level. Given their dynamic nature, the excess liquidity measures under review are - in the light of long and variable lags of monetary policy - very useful tools to quantify future price pressures. In addition, excess liquidity measures consider inflation as a purely monetary phenomenon: neither the output gap nor liquidity gap - although both form an integral part of the concepts - an be held responsible for inducing a persistent rise in the price level. Despite strong theoretical support, the usefulness of excess liquidity measures depends on the stability of money demand, a question which has of course to be answered in the realm of empirical research. --P-star,excess liquidity,monetary policy,ECB
