Trident: Improving Malware Detection with LLMs and Behavioral Features

Traditionally, machine learning methods for PE malware detection have relied on static features like byte histograms, string information, and PE header contents. One barrier to incorporating dynamic analysis features has been the semi-structured nature of sandbox behavior reports. We show that,...

Towards Certified Malware Detection: Provable Guarantees against Evasion Attacks

Machine learning-based static malware detectors remain vulnerable to adversarial evasion techniques, such as metamorphic engine mutations. To address this vulnerability, we propose a certifiably robust malware detection framework based on randomized smoothing through feature ablation and targeted...

83% of Ivanti EPMM Exploits Linked to Single IP on Bulletproof Hosting Infrastructure

A significant chunk of the exploitation attempts targeting a newly disclosed security flaw in Ivanti Endpoint Manager Mobile EPMM can be traced back to a single IP address on bulletproof hosting infrastructure offered by PROSPERO. Threat intelligence firm GreyNoise said it recorded 417 exploitati...

Researchers Find 175,000 Publicly Exposed Ollama AI Servers Across 130 Countries

A new joint investigation by SentinelOne SentinelLABS, and Censys has revealed that the open-source artificial intelligence AI deployment has created a vast "unmanaged, publicly accessible layer of AI compute infrastructure" that spans 175,000 unique Ollama hosts across 130 countries. These...

SecureSplit: Mitigating Backdoor Attacks in Split Learning

Split Learning SL offers a framework for collaborative model training that respects data privacy by allowing participants to share the same dataset while maintaining distinct feature sets. However, SL is susceptible to backdoor attacks, in which malicious clients subtly alter their embeddings to...

Efficient Private Inference Based on Helper-Assisted Malicious Security Dishonest Majority MPC

Private inference based on Secure Multi-Party Computation MPC addresses data privacy risks in Machine Learning as a Service MLaaS. However, existing MPC-based private inference frameworks focuses on semi-honest or honest majority models, whose threat models are overly idealistic, while malicious...

Formal Security Analysis of SPV Clients Versus Home-Based Full Nodes in Bitcoin-Derived Systems

This paper presents a mathematically rigorous formal analysis of Simplified Payment Verification SPV clients, as specified in Section 8 of the original Bitcoin white paper, versus non-mining full nodes operated by home users. It defines security as resistance to divergence from global consensus a...

Co-PatcheR: Collaborative Software Patching with Component(S)-Specific Small Reasoning Models

Motivated by the success of general-purpose large language models LLMs in software patching, recent works started to train specialized patching models. Most works trained one model to handle the end-to-end patching pipeline including issue localization, patch generation, and patch validation...

Enhancing Security and Strengthening Defenses in Automated Short-Answer Grading Systems

This study examines vulnerabilities in transformer-based automated short-answer grading systems used in medical education, with a focus on how these systems can be manipulated through adversarial gaming strategies. Our research identifies three main types of gaming strategies that exploit the...

Host(s) + majority can steal assets of minority+other hosts without any option for minority(+otherhosts) to ragequit.

Lines of code Vulnerability details Impact The ragequit functionality is put in place to protect the rights of the minority, who are not in support of a proposal, and allow them to withdraw their share of assets and exit the party. In some cases, minority will not have the opportunity to ragequit...

The 51% majority can hijack the party's precious tokens through an arbitrary call proposal if the AddPartyCardsAuthority contract is added as an authority in the party.

Lines of code Vulnerability details Pre-requisite knowledge & an overview of the features in question 1. The AddPartyCardsAuthority contract: The AddPartyCardsAuthority contract is a contract designed to be integrated into a Party and it has only one purpose, and it is to mint new party governanc...

A majority attack can steal precious NFT from the party by crafting and chaining two proposals

Lines of code Vulnerability details Description The PartyGovernance system has many defenses in place to protect against a majority holder stealing the NFT. Majority cannot exfiltrate the ETH gained from selling precious NFT via any proposal, and it's impossible to sell NFT for any asset except...

Early contributor can always become majority of crowdfund leading to rugging risks.

Lines of code Vulnerability details Description Voting power is distributed to crowdfund contributors according to the amount contributed divided by NFT purchase price. Attacker can call the buy function of BuyCrowdfund / CollectionBuyCrowdfund, and use only the first X amount of contribution fro...

A majority attack can easily bypass Zora auction stage in OpenseaProposal and steal the NFT from the party.

Lines of code Vulnerability details Description The PartyGovernance system has many defenses in place to protect against a majority holder stealing the NFT. One of the main protections is that before listing the NFT on Opensea for a proposal-supplied price, it must first try to be auctioned off o...

ArbitraryCallsProposal.sol and ListOnOpenseaProposal.sol safeguards can be bypassed by cancelling in-progress proposal allowing the majority to steal NFT

Lines of code Vulnerability details Note: PartyDAO acknowledges that "canceling an InProgress proposal mid-step can leave the governance party in a vulnerable or undesirable state because there is no cleanup logic run during a cancel" in the "Known Issues / Topics" section of the contest readme. ...

Users Can Frontrun Token Distributions Using Flashloans

Lines of code Vulnerability details Impact The collector suite of contracts will actively send ANC token distributions to staked ANC token holders. However, because it is known beforehand that a distribution will be made to the governance contract, users can abuse this to frontrun distributions b...

Undefined behavior for DAO and GRANT vote proposals in DAO.sol

Handle 0xRajeev Vulnerability details Impact Given that there are only three proposal types GRANT, UTILS, REWARD that are actionable, it is unclear if 'DAO' type checked in voteProposal is a typographical error and should really be 'GRANT'. Otherwise, GRANT proposals will only require quorum 33%...
