Cybersecurity researchers have called attention to a novel phishing campaign that leverages corrupted Microsoft Office documents and ZIP archives as a way to bypass email defenses. "The ongoing attack evades #antivirus software, prevents uploads to sandboxes, and bypasses Outlook's spam filters, allowing the malicious emails to reach your inbox," ANY.RUN said in a series of posts on X. The malicious activity entails sending emails containing ZIP archives or Office attachments that are intentionally corrupted in such a way that they cannot be scanned by security tools. These messages aim to trick users into opening the attachments with false promises of employee benefits and bonuses. In other words, the corrupted state of the files means that they are not flagged as suspicious or malicious by email filters and antivirus software. However, the attack still works because it takes advantage of the built-in recovery mechanisms of programs like Word, Outlook, and WinRAR ...

The North Korea-aligned threat actor known as Kimsuky has been linked to a series of phishing attacks that involve sending email messages that originate from Russian sender addresses to ultimately conduct credential theft. "Phishing emails were sent mainly through email services in Japan and Korea until early September," South Korean cybersecurity company Genians said . "Then, from mid-September, some phishing emails disguised as if they were sent from Russia were observed." This entails the abuse of VK's Mail.ru email service, which supports five different alias domains, including mail.ru, internet.ru, bk.ru, inbox.ru, and list.ru. Genians said it has observed the Kimsuky actors leveraging all the aforementioned sender domains for phishing campaigns that masquerade as financial institutions and internet portals like Naver. Other phishing attacks have entailed sending messages that mimic Naver's MYBOX cloud storage service and aim to trick users into ...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

The rise of SaaS and cloud-based work environments has fundamentally altered the cyber risk landscape. With more than 90% of organizational network traffic flowing through browsers and web applications, companies are facing new and serious cybersecurity threats. These include phishing attacks, data leakage, and malicious extensions. As a result, the browser also becomes a vulnerability that needs to be protected. LayerX has released a comprehensive guide titled "Kickstarting Your Browser Security Program" This in-depth guide serves as a roadmap for CISOs and security teams looking to secure browser activities within their organization; including step-by-step instructions, frameworks, and use cases. Below, we bring its main highlights. Prioritizing Browser Security Browsers now serve as the primary interface for SaaS applications, creating new malicious opportunities for cyber adversaries. The risks include: Data leakage - Browsers can expose sensitive data by allowing empl...

Cybersecurity researchers are calling attention to a new sophisticated tool called GoIssue that can be used to send phishing messages at scale targeting GitHub users. The program, first marketed by a threat actor named cyberdluffy (aka Cyber D' Luffy) on the Runion forum earlier this August, is advertised as a tool that allows criminal actors to extract email addresses from public GitHub profiles and send bulk emails directly to user inboxes. "Whether you're aiming to reach a specific audience or expand your outreach, GoIssue offers the precision and power you need," the threat actor claimed in their post. "GoIssue can send bulk emails to GitHub users, directly to their inboxes, targeting any recipient." SlashNext said the tool marks a "dangerous shift in targeted phishing" that could act as a gateway to source code theft, supply chain attacks, and corporate network breaches via compromised developer credentials. "Armed with this inform...

Cybersecurity researchers have flagged a new ransomware family called Ymir that was deployed in an attack two days after systems were compromised by a stealer malware called RustyStealer. "Ymir ransomware introduces a unique combination of technical features and tactics that enhance its effectiveness," Russian cybersecurity vendor Kaspersky said . "Threat actors leveraged an unconventional blend of memory management functions – malloc, memmove, and memcmp – to execute malicious code directly in the memory. This approach deviates from the typical sequential execution flow seen in widespread ransomware types, enhancing its stealth capabilities." Kaspersky said it observed the ransomware used in a cyber attack targeting an unnamed organization in Colombia, with the threat actors previously delivering the RustyStealer malware to gather corporate credentials. It's believed that the stolen credentials were used to gain unauthorized access to the company's n...

Cybersecurity researchers have discovered a malicious package on the Python Package Index (PyPI) that has racked up thousands of downloads for over three years while stealthily exfiltrating developers' Amazon Web Services (AWS) credentials. The package in question is " fabrice ," which typosquats a popular Python library known as " fabric ," which is designed to execute shell commands remotely over SSH.  While the legitimate package has over 202 million downloads, its malicious counterpart has been downloaded more than 37,100 times to date. As of writing, "fabrice" is still available for download from PyPI. It was first published in March 2021. The typosquatting package is designed to exploit the trust associated with "fabric," incorporating "payloads that steal credentials, create backdoors, and execute platform-specific scripts," security firm Socket said . "Fabrice" is designed to carry out its malicious actions ...

Cybersecurity researchers have flagged a "massive" campaign that targets exposed Git configurations to siphon credentials, clone private repositories, and even extract cloud credentials from the source code. The activity, codenamed EMERALDWHALE , is estimated to have collected over 10,000 private repositories and stored in an Amazon S3 storage bucket belonging to a prior victim. The bucket, consisting of no less than 15,000 stolen credentials, has since been taken down by Amazon. "The stolen credentials belong to Cloud Service Providers (CSPs), Email providers, and other services," Sysdig said in a report. "Phishing and spam seem to be the primary goal of stealing the credentials." The multi-faceted criminal operation, while not sophisticated, has been found to leverage an arsenal of private tools to steal credentials as well as scrape Git config files, Laravel .env files, and raw web data. It has not been attributed to any known threat actor or grou...

In the modern, browser-centric workplace, the corporate identity acts as the frontline defense for organizations. Often referred to as "the new perimeter", the identity stands between safe data management and potential breaches. However, a new report reveals how enterprises are often unaware of how their identities are being used across various platforms. This leaves them vulnerable to data breaches, account takeovers, and credential theft. The "Enterprise Identity Threat Report 2024" ( download here ) is based on exclusive data available only to the LayerX Browser Security platform. This data derives from LayerX's unique visibility into every user action in the browser, across industries. It provides a detailed analysis of emerging risks and uncovered hidden threats.

Unknown threat actors have been observed attempting to exploit a now-patched security flaw in the open-source Roundcube webmail software as part of a phishing attack designed to steal user credentials. Russian cybersecurity company Positive Technologies said it discovered last month an email that was sent to an unspecified governmental organization located in one of the Commonwealth of Independent States (CIS) countries. However, it bears noting that the message was originally sent in June 2024. "The email appeared to be a message without text, containing only an attached document," it said in an analysis published earlier this week. "However, the email client didn't show the attachment. The body of the email contained distinctive tags with the statement eval(atob(...)), which decode and execute JavaScript code." The attack chain, per Positive Technologies, is an attempt to exploit CVE-2024-37383 (CVSS score: 6.1), a stored cross-site scripting ( XSS ) v...

Microsoft and the U.S. Department of Justice (DoJ) on Thursday announced the seizure of 107 internet domains used by state-sponsored threat actors with ties to Russia to facilitate computer fraud and abuse in the country. "The Russian government ran this scheme to steal Americans' sensitive information, using seemingly legitimate email accounts to trick victims into revealing account credentials," said Deputy Attorney General Lisa Monaco. The activity has been attributed to a threat actor called COLDRIVER , which is also known by the names Blue Callisto, BlueCharlie (or TAG-53), Calisto (alternately spelled Callisto), Dancing Salome, Gossamer Bear, Iron Frontier, Star Blizzard (formerly SEABORGIUM), TA446, and UNC4057. Active since at least 2012, the group is assessed to be an operational unit within Center 18 of the Russian Federal Security Service (FSB). In December 2023, the U.K. and U.S. governments sanctioned two members of the group – Aleksandrovich Peretyat...

More than 140,000 phishing websites have been found linked to a phishing-as-a-service (PhaaS) platform named Sniper Dz over the past year, indicating that it's being used by a large number of cybercriminals to conduct credential theft. "For prospective phishers, Sniper Dz offers an online admin panel with a catalog of phishing pages," Palo Alto Networks Unit 42 researchers Shehroze Farooqi, Howard Tong, and Alex Starov said in a technical report. "Phishers can either host these phishing pages on Sniper Dz-owned infrastructure or download Sniper Dz phishing templates to host on their own servers." Perhaps what makes it even more lucrative is that these services are provided for free. That said, the credentials harvested using the phishing sites are also exfiltrated to the operators of the PhaaS platform, a technique that Microsoft calls double theft . PhaaS platforms have become an increasingly common way for aspiring threat actors to enter the world of cy...

Cybersecurity researchers have warned of ongoing phishing campaigns that abuse refresh entries in HTTP headers to deliver spoofed email login pages that are designed to harvest users' credentials. "Unlike other phishing webpage distribution behavior through HTML content, these attacks use the response header sent by a server, which occurs before the processing of the HTML content," Palo Alto Networks Unit 42 researchers Yu Zhang, Zeyu You, and Wei Wang said . "Malicious links direct the browser to automatically refresh or reload a web page immediately, without requiring user interaction." Targets of the large-scale activity, observed between May and July 2024, include large corporations in South Korea, as well as government agencies and schools in the U.S. As many as 2,000 malicious URLs have been associated with the campaigns. Over 36% of the attacks have singled out the business-and-economy sector, followed by financial services (12.9%), government (6.9%)...

The threat actors behind a recently observed Qilin ransomware attack have stolen credentials stored in Google Chrome browsers on a small set of compromised endpoints. The use of credential harvesting in connection with a ransomware infection marks an unusual twist, and one that could have cascading consequences, cybersecurity firm Sophos said in a Thursday report. The attack, detected in July 2024, involved infiltrating the target network via compromised credentials for a VPN portal that lacked multi-factor authentication (MFA), with the threat actors conducting post-exploitation actions 18 days after initial access took place. "Once the attacker reached the domain controller in question, they edited the default domain policy to introduce a logon-based Group Policy Object (GPO) containing two items," researchers Lee Kirkpatrick, Paul Jacobs, Harshal Gosalia, and Robert Weiland said . The first of them is a PowerShell script named "IPScanner.ps1" that's desi...

A large-scale extortion campaign has compromised various organizations by taking advantage of publicly accessible environment variable files (.env) that contain credentials associated with cloud and social media applications. "Multiple security missteps were present in the course of this campaign, including the following: Exposing environment variables, using long-lived credentials, and absence of least privilege architecture," Palo Alto Networks Unit 42 said in a Thursday report. The campaign is notable for setting up its attack infrastructure within the infected organizations' Amazon Web Services (AWS) environments and using them as a launchpad for scanning more than 230 million unique targets for sensitive data. With 110,000 domains targeted, the malicious activity is said to have netted over 90,000 unique variables in the .env files, out of which 7,000 belonged to organizations' cloud services and 1,500 variables are linked to social media accounts. "T...

Cybersecurity researchers have discovered a malicious package on the Python Package Index (PyPI) repository that targets Apple macOS systems with the goal of stealing users' Google Cloud credentials from a narrow pool of victims. The package, named "lr-utils-lib," attracted a total of 59 downloads before it was taken down. It was uploaded to the registry in early June 2024. "The malware uses a list of predefined hashes to target specific macOS machines and attempts to harvest Google Cloud authentication data," Checkmarx researcher Yehuda Gelb said in a Friday report. "The harvested credentials are sent to a remote server." An important aspect of the package is that it first checks if it has been installed on a macOS system, and only then proceeds to compare the system's Universally Unique Identifier (UUID) against a hard-coded list of 64 hashes. If the compromised machine is among those specified in the predefined set, it attempts to access...
