Cybersecurity researchers have detected a new wave of phishing attacks that aim to deliver an ever-evolving information stealer referred to as  StrelaStealer . The campaigns impact more than 100 organizations in the E.U. and the U.S., Palo Alto Networks Unit 42 researchers said in a new report published today. "These campaigns come in the form of spam emails with attachments that eventually launch the StrelaStealer's DLL payload," researchers Benjamin Chang, Goutam Tripathy, Pranay Kumar Chhaparwal, Anmol Maurya, and Vishwa Thothathri said . "In an attempt to evade detection, attackers change the initial email attachment file format from one campaign to the next, to prevent detection from the previously generated signature or patterns." First disclosed in November 2022, StrelaStealer is  equipped  to siphon email login data from well-known email clients and exfiltrate them to an attacker-controlled server. Since then, two large-scale campaigns involving the ma...

Cybersecurity researchers have shared details of a now-patched security vulnerability in Amazon Web Services (AWS) Managed Workflows for Apache Airflow ( MWAA ) that could be potentially exploited by a malicious actor to hijack victims' sessions and achieve remote code execution on underlying instances. The vulnerability, now addressed by AWS, has been codenamed  FlowFixation  by Tenable. "Upon taking over the victim's account, the attacker could have performed tasks such as reading connection strings, adding configurations and triggering directed acyclic graphs (DAGS)," senior security researcher Liv Matan  said  in a technical analysis. "Under certain circumstances such actions can result in RCE on the instance that underlies the MWAA, and in lateral movement to other services." The root cause of the vulnerability, per the cybersecurity firm, is a combination of  session fixation  on the web management panel of AWS MWAA and an AWS domain misconfigur...

A China-linked threat cluster leveraged security flaws in Connectwise ScreenConnect and F5 BIG-IP software to deliver custom malware capable of delivering additional backdoors on compromised Linux hosts as part of an "aggressive" campaign. Google-owned Mandiant is  tracking  the activity under its uncategorized moniker  UNC5174  (aka Uteus or Uetus), describing it as a "former member of Chinese hacktivist collectives that has since shown indications of acting as a contractor for China's Ministry of State Security (MSS) focused on executing access operations." The threat actor is believed to have orchestrated widespread attacks against Southeast Asian and U.S. research and education institutions, Hong Kong businesses, charities and non-governmental organizations (NGOs), and U.S. and U.K. government organizations between October and November 2023, and again in February 2024 using the ScreenConnect bug. Initial access to target environments is facilitated by t...

A massive malware campaign dubbed  Sign1  has compromised over 39,000 WordPress sites in the last six months, using malicious JavaScript injections to redirect users to scam sites. The most recent variant of the malware is estimated to have infected no less than 2,500 sites over the past two months alone, Sucuri said in a report published this week. The attacks entail injecting rogue JavaScript into legitimate HTML widgets and plugins that allow for arbitrary JavaScript and other code to be inserted, providing attackers with an opportunity to add their malicious code. The XOR-encoded JavaScript code is subsequently decoded and used to execute a JavaScript file hosted on a remote server, which ultimately facilitates redirects to a  VexTrio -operated traffic distribution system (TDS) but only if certain criteria are met. What's more, the malware uses time-based randomization to fetch dynamic URLs that change every 10 minutes to get around blocklists. These domains are...

The U.S. Department of Justice (DoJ), along with 16 other state and district attorneys general, on Thursday  accused  Apple of illegally maintaining a monopoly over smartphones, thereby undermining, among other things, the security and privacy of users when messaging non-iPhone users. "Apple wraps itself in a cloak of privacy, security, and consumer preferences to justify its anticompetitive conduct," the landmark antitrust lawsuit  said . "Apple deploys privacy and security justifications as an elastic shield that can stretch or contract to serve Apple's financial and business interests." "Apple selectively compromises privacy and security interests when doing so is in Apple's own financial interest – such as degrading the security of text messages, offering governments and certain companies the chance to access more private and secure versions of app stores, or accepting billions of dollars each year for choosing Google as its default search engin...

The data wiping malware called  AcidPour  may have been deployed in attacks targeting four telecom providers in Ukraine, new findings from SentinelOne show. The cybersecurity firm also confirmed connections between the malware and AcidRain, tying it to threat activity clusters associated with Russian military intelligence. "AcidPour's expanded capabilities would enable it to better disable embedded devices including networking, IoT, large storage (RAIDs), and possibly ICS devices running Linux x86 distributions," security researchers Juan Andres Guerrero-Saade and Tom Hegel  said . AcidPour is a variant of  AcidRain , a wiper that was used to render Viasat KA-SAT modems operable at the onset of the Russo-Ukrainian war in early 2022 and cripple Ukraine's military communications. It also builds upon the latter's features, while targeting Linux systems running on x86 architecture. AcidRain, on the other hand, is compiled for MIPS architecture. Where AcidRain w...

The Russia-linked threat actor known as Turla infected several systems belonging to an unnamed European non-governmental organization (NGO) in order to deploy a backdoor called TinyTurla-NG (TTNG) . "The attackers compromised the first system, established persistence and added exclusions to antivirus products running on these endpoints as part of their preliminary post-compromise actions," Cisco Talos  said  in a new report published today. "Turla then opened additional channels of communication via Chisel for data exfiltration and to pivot to additional accessible systems in the network." There is evidence indicating that the infected systems were breached as early as October 2023, with Chisel deployed in December 2023 and data exfiltration taking place via the tool a month later, around January 12, 2024. TinyTurla-NG was  first documented  by the cybersecurity company last month after it was found to be used in connection with a cyber attack targeting a Poli...

New research has discovered over 800 packages in the npm registry which have discrepancies from their registry entries, out of which 18 have been found to exploit a technique called  manifest confusion . The findings come from cybersecurity firm JFrog, which said the issue could be exploited by threat actors to trick developers into running malicious code. "It's an actual threat since developers may be tricked into downloading packages that look innocent, but whose hidden dependencies are actually malicious," security researcher Andrey Polkovnichenko told The Hacker News. Manifest confusion was  first documented  in July 2023, when security researcher Darcy Clarke found that mismatches in manifest and package metadata could be weaponized to stage software supply chain attacks. The problem stems from the fact that the npm registry does not validate whether the manifest file contained in the tarball (package.json) matches the manifest data provided to the npm server d...

Cybersecurity researchers have shed light on a tool referred to as  AndroxGh0st  that's used to target Laravel applications and steal sensitive data. "It works by scanning and taking out important information from .env files, revealing login details linked to AWS and Twilio," Juniper Threat Labs researcher Kashinath T Pattan  said . "Classified as an SMTP cracker, it exploits SMTP using various strategies such as credential exploitation, web shell deployment, and vulnerability scanning." AndroxGh0st has been detected in the wild since at least 2022, with threat actors leveraging it to access Laravel environment files and steal credentials for various cloud-based applications like Amazon Web Services (AWS), SendGrid, and Twilio. Attack chains involving the Python malware are known to exploit known security flaws in Apache HTTP Server, Laravel Framework, and PHPUnit to gain initial access and for privilege escalation and persistence. Earlier this January, U...

In today's digital-first business environment dominated by SaaS applications, organizations increasingly depend on third-party vendors for essential cloud services and software solutions. As more vendors and services are added to the mix, the complexity and potential vulnerabilities within the  SaaS supply chain  snowball quickly. That's why effective vendor risk management (VRM) is a critical strategy in identifying, assessing, and mitigating risks to protect organizational assets and data integrity. Meanwhile, common approaches to vendor risk assessments are too slow and static for the modern world of SaaS. Most organizations have simply adapted their legacy evaluation techniques for on-premise software to apply to SaaS providers. This not only creates massive bottlenecks, but also causes organizations to inadvertently accept far too much risk. To effectively adapt to the realities of modern work, two major aspects need to change: the timeline of initial assessment must s...

GitHub on Wednesday announced that it's making available a feature called code scanning autofix in public beta for all  Advanced Security customers  to provide targeted recommendations in an effort to avoid introducing new security issues. "Powered by  GitHub Copilot  and  CodeQL , code scanning autofix covers more than 90% of alert types in JavaScript, Typescript, Java, and Python, and delivers code suggestions shown to remediate more than two-thirds of found vulnerabilities with little or no editing," GitHub's Pierre Tempel and Eric Tooley  said . The capability,  first previewed  in November 2023, leverages a combination of CodeQL, Copilot APIs, and OpenAI GPT-4 to generate code suggestions. The Microsoft-owned subsidiary also said it plans to add support for more programming languages, including C# and Go, in the future. Code scanning autofix is designed to help developers resolve vulnerabilities as they code by generating potential fixes ...
