Malicious actors are using a cloud attack tool named Xeon Sender to conduct SMS phishing and spam campaigns on a large scale by abusing legitimate services. "Attackers can use Xeon to send messages through multiple software-as-a-service (SaaS) providers using valid credentials for the service providers," SentinelOne security researcher Alex Delamotte said in a report shared with The Hacker News. Examples of the services used to facilitate the en masse distribution of SMS messages include Amazon Simple Notification Service (SNS), Nexmo, Plivo, Proovl, Send99, Telesign, Telnyx, TextBelt, Twilio. It's important to note here that the activity does not exploit any inherent weaknesses in these providers. Rather, the tool uses legitimate APIs to conduct bulk SMS spam attacks. It joins tools like SNS Sender that have increasingly become a way to send bulk smishing messages and ultimately capture sensitive information from targets. Distributed via Telegram and hacking fo...

A newly patched security flaw in Microsoft Windows was exploited as a zero-day by Lazarus Group , a prolific state-sponsored actor affiliated with North Korea. The security vulnerability, tracked as CVE-2024-38193 (CVSS score: 7.8), has been described as a privilege escalation bug in the Windows Ancillary Function Driver (AFD.sys) for WinSock. "An attacker who successfully exploited this vulnerability could gain SYSTEM privileges," Microsoft said in an advisory for the flaw last week. It was addressed by the tech giant as part of its monthly Patch Tuesday update. Credited with discovering and reporting the flaw are Gen Digital researchers Luigino Camastra and Milánek. Gen Digital owns a number of security and utility software brands like Norton, Avast, Avira, AVG, ReputationDefender, and CCleaner. "This flaw allowed them to gain unauthorized access to sensitive system areas," the company disclosed last week, adding it discovered the exploitation in early J...

Cybersecurity researchers have discovered new infrastructure linked to a financially motivated threat actor known as FIN7 . The two clusters of potential FIN7 activity "indicate communications inbound to FIN7 infrastructure from IP addresses assigned to Post Ltd (Russia) and SmartApe (Estonia), respectively," Team Cymru said in a report published this week as part of a joint investigation with Silent Push and Stark Industries Solutions. The findings build on a recent report from Silent Push, which found several Stark Industries IP addresses that are solely dedicated to hosting FIN7 infrastructure. The latest analysis indicates that the hosts linked to the e-crime group were likely procured from one of Stark's resellers. "Reseller programs are common in the hosting industry; many of the largest VPS (virtual private server) providers offer such services," the cybersecurity company said. "Customers procuring infrastructure via resellers generally must ...

While phishing and ransomware dominate headlines, another critical risk quietly persists across most enterprises: exposed Git repositories leaking sensitive data. A risk that silently creates shadow access into core systems Git is the backbone of modern software development, hosting millions of repositories and serving thousands of organizations worldwide. Yet, amid the daily hustle of shipping code, developers may inadvertently leave behind API keys, tokens, or passwords in configuration files and code files, effectively handing attackers the keys to the kingdom. This isn't just about poor hygiene; it's a systemic and growing supply chain risk. As cyber threats become more sophisticated, so do compliance requirements. Security frameworks like NIS2, SOC2, and ISO 27001 now demand proof that software delivery pipelines are hardened and third-party risk is controlled. The message is clear: securing your Git repositories is no longer optional, it's essential. Below, we look at the ris...

OpenAI on Friday said it banned a set of accounts linked to what it said was an Iranian covert influence operation that leveraged ChatGPT to generate content that, among other things, focused on the upcoming U.S. presidential election. "This week we identified and took down a cluster of ChatGPT accounts that were generating content for a covert Iranian influence operation identified as Storm-2035," OpenAI said . "The operation used ChatGPT to generate content focused on a number of topics — including commentary on candidates on both sides in the U.S. presidential election – which it then shared via social media accounts and websites." The artificial intelligence (AI) company said the content did not achieve any meaningful engagement, with a majority of the social media posts receiving negligible to no likes, shares, and comments. It further noted it had found little evidence that the long-form articles created using ChatGPT were shared on social media platforms....

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...

A 27-year-old Russian national has been sentenced to over three years in prison in the U.S. for peddling financial information, login credentials, and other personally identifying information (PII) on a now-defunct dark web marketplace called Slilpp . Georgy Kavzharadze, 27, of Moscow, Russia, pleaded guilty to one count of conspiracy to commit bank fraud and wire fraud earlier this February. In addition to a 40-month jail term, Kavzharadze has been ordered to pay $1,233,521.47 in restitution. The defendant, who went by the online monikers TeRorPP, Torqovec, and PlutuSS, is believed to have listed over 626,100 stolen login credentials for sale on Slilpp and sold more than 297,300 of them on the illicit marketplace between July 2016 and May 2021. "Those credentials were subsequently linked to $1.2 million in fraudulent transactions," the U.S. Department of Justice (DoJ) said . "On May 27, 2021, Kavzharadze's account on Slilpp listed 240,495 login credentials fo...

Cybersecurity researchers have shed light on a sophisticated information stealer campaign that impersonates legitimate brands to distribute malware like DanaBot and StealC . The activity cluster, orchestrated by Russian-speaking cybercriminals and collectively codenamed Tusk, is said to encompass several sub-campaigns, leveraging the reputation of the platforms to trick users into downloading the malware using bogus sites and social media accounts. "All the active sub-campaigns host the initial downloader on Dropbox," Kaspersky researchers Elsayed Elrefaei and AbdulRhman Alfaifi said . "This downloader is responsible for delivering additional malware samples to the victim's machine, which are mostly info-stealers (DanaBot and StealC) and clippers." Of the 19 sub-campaigns identified to date, three are said to be currently active. The name "Tusk" is a reference to the word "Mammoth" used by the threat actors in log messages associated with t...

Chinese-speaking users are the target of an ongoing campaign that distributes a malware known as ValleyRAT. "ValleyRAT is a multi-stage malware that utilizes diverse techniques to monitor and control its victims and deploy arbitrary plugins to cause further damage," Fortinet FortiGuard Labs researchers Eduardo Altares and Joie Salvio said . "Another noteworthy characteristic of this malware is its heavy usage of shellcode to execute its many components directly in memory, significantly reducing its file footprint in the victim's system." Details about the campaign first emerged in June 2024, when Zscaler ThreatLabz detailed attacks involving an updated version of the malware. Exactly how the latest iteration of ValleyRAT is distributed is currently not known, although previous campaigns have leveraged email messages containing URLs pointing to compressed executables. "Based on the filenames of the executables we found, they're likely using phis...

A large percentage of Google's own Pixel devices shipped globally since September 2017 included dormant software that could be used to stage nefarious attacks and deliver various kinds of malware. The issue manifests in the form of a pre-installed Android app called "Showcase.apk" that comes with excessive system privileges, including the ability to remotely execute code and install arbitrary packages on the device, according to mobile security firm iVerify. "The application downloads a configuration file over an unsecure connection and can be manipulated to execute code at the system level," it said in an analysis published jointly with Palantir Technologies and Trail of Bits. "The application retrieves the configuration file from a single U.S.-based, AWS-hosted domain over unsecured HTTP, which leaves the configuration vulnerable and can make the device vulnerable." The app in question is called Verizon Retail Demo Mode ("com.customermob...

Russian and Belarusian non-profit organizations, Russian independent media, and international non-governmental organizations active in Eastern Europe have become the target of two separate spear-phishing campaigns orchestrated by threat actors whose interests align with that of the Russian government. While one of the campaigns – dubbed River of Phish – has been attributed to COLDRIVER , an adversarial collective with ties to Russia's Federal Security Service (FSB), the second set of attacks have been deemed the work of a previously undocumented threat cluster codenamed COLDWASTREL. Targets of the campaigns also included prominent Russian opposition figures-in-exile, officials and academics in the US think tank and policy space, and a former U.S. ambassador to Ukraine, according to a joint investigation from Access Now and the Citizen Lab. "Both kinds of attacks were highly tailored to better deceive members of the target organizations," Access Now said . "The m...

The Emergence of Identity Threat Detection and Response Identity Threat Detection and Response (ITDR) has emerged as a critical component to effectively detect and respond to identity-based attacks. Threat actors have shown their ability to compromise the identity infrastructure and move laterally into IaaS, Saas, PaaS and CI/CD environments. Identity Threat Detection and Response solutions help organizations better detect suspicious or malicious activity in their environment. ITDR solutions give security teams the ability to help teams answer the question "What's happening right now in my environment - what are my identities doing in my environments." Human and Non-Human Identities As outlined in the ITDR Solution Guide, comprehensive ITDR solutions cover both human and non-human identities. Human identities entail the workforce (employees), guests (contractors), and vendors. Non-human identities include tokens, keys, service accounts, and bots. Multi- environment ITDR solutions c...

A cybercrime group with links to the RansomHub ransomware has been observed using a new tool designed to terminate endpoint detection and response (EDR) software on compromised hosts, joining the likes of other similar programs like AuKill (aka AvNeutralizer) and Terminator . The EDR-killing utility has been dubbed EDRKillShifter by cybersecurity company Sophos, which discovered the tool in connection with a failed ransomware attack in May 2024. "The EDRKillShifter tool is a 'loader' executable – a delivery mechanism for a legitimate driver that is vulnerable to abuse (also known as a 'bring your own vulnerable driver,' or BYOVD , tool)," security researcher Andreas Klopsch said . "Depending on the threat actor's requirements, it can deliver a variety of different driver payloads." RansomHub , a suspected rebrand of the Knight ransomware, surfaced in February 2024, leveraging known security flaws to obtain initial access and drop legitimate rem...

A newly discovered attack vector in GitHub Actions artifacts dubbed ArtiPACKED could be exploited to take over repositories and gain access to organizations' cloud environments. "A combination of misconfigurations and security flaws can make artifacts leak tokens, both of third party cloud services and GitHub tokens, making them available for anyone with read access to the repository to consume," Palo Alto Networks Unit 42 researcher Yaron Avital said in a report published this week. "This allows malicious actors with access to these artifacts the potential of compromising the services to which these secrets grant access." The cybersecurity company said it primarily observed the leakage of GitHub tokens (e.g., GITHUB_TOKEN and ACTIONS_RUNTIME_TOKEN), which could not only give malicious actors unauthorized access to the repositories, but also grant them the ability to poison the source code and get it pushed to production via CI/CD workflows. Artifacts in...

A previously unknown threat actor has been attributed to a spate of attacks targeting Azerbaijan and Israel with an aim to steal sensitive data. The attack campaign, detected by NSFOCUS on July 1, 2024, leveraged spear-phishing emails to single out Azerbaijani and Israeli diplomats. The activity is being tracked under the moniker Actor240524 . "Actor240524 possesses the ability to steal secrets and modify file data, using a variety of countermeasures to avoid overexposure of attack tactics and techniques," the cybersecurity company said in an analysis published last week. The attack chains commence with the use of phishing emails bearing Microsoft Word documents that, upon opening, urge the recipients to " Enable Content " and run a malicious macro responsible for executing an intermediate loader payload codenamed ABCloader ("MicrosoftWordUpdater.log"). In the next step, ABCloader acts as a conduit to decrypt and load a DLL malware called ABCsync (...
