A comprehensive analysis of the cryptographic protocols used in the Swiss encrypted messaging application Threema has revealed a number of loopholes that could be exploited to break authentication protections and even recover users' private keys. The seven attacks span three different threat models,  according  to ETH Zurich researchers Kenneth G. Paterson, Matteo Scarlata, and Kien Tuong Truong, who reported the issues to Threema on October 3, 2022. The weaknesses have since been addressed as part of  updates  released by the company on November 29, 2022. Threema is an encrypted messaging app that's used by more than 11 million users as of October 2022. "Security and privacy are deeply ingrained in Threema's DNA," the company  claims  on its website. Officially used by the Swiss Government and the Swiss Army, it's also advertised as a secure alternative alongside other services such as Signal, Meta-owned WhatsApp, and Telegram. While Threema has been ...

A new malware campaign has been observed targeting Italy with phishing emails designed to deploy an information stealer on compromised Windows systems. "The info-stealer malware steals sensitive information like system info, crypto wallet and browser histories, cookies, and credentials of crypto wallets from victim machines," Uptycs security researcher Karthickkumar Kathiresan  said  in a report. Details of the campaign were first  disclosed  by Milan-based IT services firm SI.net last month. The multi-stage infection sequence commences with an invoice-themed phishing email containing a link that, when clicked, downloads a password-protected ZIP archive file, which harbors two files: A shortcut (.LNK) file and a batch (.BAT) file. Irrespective of which file is launched, the attack chain remains the same, as opening the shortcut file fetches the same batch script designed to install the information stealer payload from a GitHub repository. This is achieved by l...

UPDATE: CVE-2022-23529 Retracted Following Review Auth0 and Unit 42 said they are formally retracting CVE-2022-23529 (CVSS score: 7.6) based on the fact that several prerequisites are essential for exploitation. The cybersecurity company said "important security checks" have been added to fix the problem. "The security issue remains a concern only when the jsonwebtoken library is used in an insecure way," the maintainers said in an advisory. "In such a scenario, if all the prerequisites are met, the issue may be exploitable; however, the source of this risk is the calling code and not the library itself." A high-severity security flaw has been disclosed in the open source jsonwebtoken (JWT) library that, if successfully exploited, could lead to remote code execution on a target server. "By exploiting this  vulnerability , attackers could achieve remote code execution (RCE) on a server verifying a maliciously crafted JSON web token (JWT) reques...

The threat actors behind the  Kinsing  cryptojacking operation have been spotted exploiting misconfigured and exposed PostgreSQL servers to obtain initial access to Kubernetes environments. A second initial access vector technique entails the use of vulnerable images, Sunders Bruskin, security researcher at Microsoft Defender for Cloud,  said  in a report last week. Kinsing has a  storied history  of targeting  containerized environments , often leveraging misconfigured open Docker daemon API ports as well as abusing newly disclosed exploits to drop cryptocurrency mining software. The threat actor, in the past, has also been discovered  employing a rootkit  to hide its presence, in addition to terminating and uninstalling competing resource-intensive services and processes. Now according to Microsoft, misconfigurations in  PostgreSQL servers  have been co-opted by the Kinsing actor to gain an initial foothold, with the company...

A group of academics has demonstrated novel attacks that leverage Text-to-SQL models to produce malicious code that could enable adversaries to glean sensitive information and stage denial-of-service (DoS) attacks. "To better interact with users, a wide range of database applications employ AI techniques that can translate human questions into SQL queries (namely  Text-to-SQL ),"  Xutan Peng , a researcher at the University of Sheffield, told The Hacker News. "We found that by asking some specially designed questions, crackers can fool Text-to-SQL models to produce malicious code. As such code is automatically executed on the database, the consequence can be pretty severe (e.g., data breaches and DoS attacks)." The  findings , which were validated against two commercial solutions  BAIDU-UNIT  and  AI2sql , mark the first empirical instance where natural language processing (NLP) models have been exploited as an attack vector in the wild. The black box ...

Earlier this year, threat actors infiltrated  Mailchimp , the popular SaaS email marketing platform. They viewed over 300 Mailchimp customer accounts and exported audience data from 102 of them. The breach was preceded by a successful phishing attempt and led to malicious attacks against Mailchimp's customers' end users. Three months later, Mailchimp was hit with  another attack . Once again, an employee's account was breached following a successful phishing attempt. While the identity of the Mailchimp accounts that had been compromised wasn't released, it's easy to see how user permission settings could have played a role in the attack. Once threat detectors breached the system, they had the access needed to utilize an internal tool that enabled them to find the data they were looking for. The attack ended when security teams were able to terminate user access, although data which had already been downloaded remained in the threat actor's hands. Introducing user permissio...

Multiple bugs affecting millions of vehicles from 16 different manufacturers could be abused to unlock, start, and track cars, plus impact the privacy of car owners. The  security vulnerabilities  were found in the automotive APIs powering Acura, BMW, Ferrari, Ford, Genesis, Honda, Hyundai, Infiniti, Jaguar, Kia, Land Rover, Mercedes-Benz, Nissan, Porsche, Rolls Royce, Toyota as well as in software from Reviver, SiriusXM, and Spireon. The flaws run a wide gamut, ranging from those that give access to internal company systems and user information to weaknesses that would allow an attacker to remotely send commands to achieve code execution. The research builds on earlier findings from late last year, when Yuga Labs researcher Sam Curry et al  detailed  security flaws in a connected vehicle service provided by SiriusXM that could potentially put cars at risk of remote attacks. The most serious of the issues, which concern Spireon's telematics solution, could have...
