The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday placed a security flaw impacting the Linux kernel in its Known Exploited Vulnerabilities ( KEV ) catalog, stating it has been actively exploited in the wild. The vulnerability, CVE-2023-0386 (CVSS score: 7.8), is an improper ownership bug in the Linux kernel that could be exploited to escalate privileges on susceptible systems. It was patched in early 2023. "Linux kernel contains an improper ownership management vulnerability, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel's OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount," the agency said. "This uid mapping bug allows a local user to escalate their privileges on the system." It's currently not known how the security flaw is being exploited in the wild. In a report published in May 2023, Datadog said the vulnerability...

A former U.S. Central Intelligence Agency (CIA) analyst has been sentenced to little more than three years in prison for unlawfully retaining and transmitting top secret National Defense Information (NDI) to people who were not entitled to receive them and for attempting to cover up the malicious activity. Asif William Rahman, 34, of Vienna, has been sentenced today to 37 months on charges of stealing and divulging classified information. He was an employee of the CIA since 2016 and had Top Secret security clearance to access Sensitive Compartmented Information (SCI) until he was terminated from his job after he was arrested last November in Cambodia. Earlier this January, Rahman pleaded guilty to two counts of willful retention and transmission of classified information related to the national defense. As previously reported by The Hacker News, Rahman retained multiple Secret and Top Secret documents without authorization on October 17, 2024, took them to his place of residence...

Veeam has rolled out patches to contain a critical security flaw impacting its Backup & Replication software that could result in remote code execution under certain conditions. The security defect, tracked as CVE-2025-23121, carries a CVSS score of 9.9 out of a maximum of 10.0. "A vulnerability allowing remote code execution (RCE) on the Backup Server by an authenticated domain user," the company said in an advisory. CVE-2025-23121 impacts all earlier version 12 builds, including 12.3.1.1139. It has been addressed in version 12.3.2 (build 12.3.2.3617). Security researchers at CODE WHITE GmbH and watchTowr have been credited with discovering and reporting the vulnerability. Cybersecurity company Rapid7 noted that the update likely addresses concerns shared by CODE WHITE in late March 2025 that the patch put in place to plug a similar hole ( CVE-2025-23120 , CVSS score: 9.9) could be bypassed. Also addressed by Veeam is another flaw in the same product (CVE-2025...

Iran has throttled internet access in the country in a purported attempt to hamper Israel's ability to conduct covert cyber operations, days after the latter launched an unprecedented attack on the country, escalating geopolitical tensions in the region. Fatemeh Mohajerani, the spokesperson of the Iranian Government, and the Iranian Cyber Police, FATA, said the internet slowdown was designed to maintain internet stability and that the move is "temporary, targeted, and controlled, to ward off cyber attacks." Data shared by NetBlocks shows a "significant reduction in internet traffic" around 5:30 p.m. local time. The development comes amid deepening conflict, with Israel and Iran trading missile attacks since Friday. These attacks have spilled over into cyberspace, as security experts warned of retaliatory cyber operations by Iranian state actors and hacktivist groups. The digital warfare unfolding behind the scenes goes two ways. Earlier this week, a pro...

A now-patched security flaw in Google Chrome was exploited as a zero-day by a threat actor known as TaxOff to deploy a backdoor codenamed Trinper . The attack, observed in mid-March 2025 by Positive Technologies, involved the use of a sandbox escape vulnerability tracked as CVE-2025-2783 (CVSS score: 8.3). Google addressed the flaw later that month after Kaspersky reported in-the-wild exploitation in a campaign dubbed Operation ForumTroll targeting various Russian organizations. "The initial attack vector was a phishing email containing a malicious link," security researchers Stanislav Pyzhov and Vladislav Lunin said . "When the victim clicked the link, it triggered a one-click exploit (CVE-2025-2783), leading to the installation of the Trinper backdoor employed by TaxOff." The phishing email is said to have been disguised as an invitation to the Primakov Readings forum – the same lure detailed by Kaspersky – urging users to click on a link that led to a fake...

Cybersecurity researchers have disclosed a now-patched security flaw in LangChain's LangSmith platform that could be exploited to capture sensitive data, including API keys and user prompts. The vulnerability, which carries a CVSS score of 8.8 out of a maximum of 10.0, has been codenamed AgentSmith by Noma Security. LangSmith is an observability and evaluation platform that allows users to develop, test, and monitor large language model (LLM) applications, including those built using LangChain. The service also offers what's called a LangChain Hub , which acts as a repository for all publicly listed prompts, agents, and models. "This newly identified vulnerability exploited unsuspecting users who adopt an agent containing a pre-configured malicious proxy server uploaded to 'Prompt Hub,'" researchers Sasi Levi and Gal Moyal said in a report shared with The Hacker News. "Once adopted, the malicious proxy discreetly intercepted all user communicatio...

Cybersecurity researchers are warning of a new phishing campaign that's targeting users in Taiwan with malware families such as HoldingHands RAT and Gh0stCringe. The activity is part of a broader campaign that delivered the Winos 4.0 malware framework earlier this January by sending phishing messages impersonating Taiwan's National Taxation Bureau, Fortinet FortiGuard Labs said in a report shared with The Hacker News. The cybersecurity company said it identified additional malware samples through continuous monitoring and that it observed the same threat actor, referred to as Silver Fox APT, using malware-laced PDF documents or ZIP files distributed via phishing emails to deliver Gh0stCringe and a malware strain based on HoldingHands RAT. It's worth noting that both HoldingHands RAT (aka Gh0stBins) and Gh0stCringe are variants of a known remote access trojan called Gh0st RAT, which is widely used by Chinese hacking groups. The starting point of the attack is a p...

The notorious cybercrime group known as Scattered Spider (aka UNC3944) that recently targeted various U.K. and U.S. retailers has begun to target major insurance companies, according to Google Threat Intelligence Group (GTIG). "Google Threat Intelligence Group is now aware of multiple intrusions in the U.S. which bear all the hallmarks of Scattered Spider activity," John Hultquist, chief analyst at GTIG, said in an email Monday. "We are now seeing incidents in the insurance industry. Given this actor's history of focusing on a sector at a time, the insurance industry should be on high alert, especially for social engineering schemes which target their help desks and call centers." Scattered Spider is the name assigned to an amorphous collective that's known for its use of advanced social engineering tactics to breach organizations. In recent months, the threat actors are believed to have forged an alliance with the DragonForce ransomware cartel in the ...

For many organizations, Active Directory (AD) service accounts are quiet afterthoughts, persisting in the background long after their original purpose has been forgotten. To make matters worse, these orphaned service accounts (created for legacy applications, scheduled tasks, automation scripts, or test environments) are often left active with non-expiring or stale passwords. It's no surprise that AD service accounts often evade routine security oversight. Security teams, overwhelmed by daily demands and lingering technical debt, often overlook service accounts (unlinked to individual users and rarely scrutinized) allowing them to quietly fade into the background. However, this obscurity makes them prime targets for attackers seeking stealthy ways into the network. And left unchecked, forgotten service accounts can serve as silent gateways for attack paths and lateral movement across enterprise environments. In this article, we'll examine the risks that forgotten AD service accounts...

Cybersecurity researchers have disclosed three security flaws in the popular Sitecore Experience Platform (XP) that could be chained to achieve pre-authenticated remote code execution. Sitecore Experience Platform is an enterprise-oriented software that provides users with tools for content management, digital marketing, and analytics and reports. The list of vulnerabilities, which are yet to be assigned CVE identifiers, is as follows - Use of hard-coded credentials Post-authenticated remote code execution via path traversal Post-authenticated remote code execution via Sitecore PowerShell Extension watchTowr Labs researcher Piotr Bazydlo said the default user account "sitecore\ServicesAPI" has a single-character password that's hard-coded to " b ." In its documentation, Sitecore advises customers against changing default user account credentials. While the user has no roles and permissions assigned in Sitecore, the attack surface management firm fou...

Ransomware has become a highly coordinated and pervasive threat, and traditional defenses are increasingly struggling to neutralize it. Today's ransomware attacks initially target your last line of defense — your backup infrastructure. Before locking up your production environment, cybercriminals go after your backups to cripple your ability to recover, increasing the odds of a ransom payout. Notably, these attacks are carefully engineered takedowns of your defenses. The threat actors disable backup agents, delete snapshots, modify retention policies, encrypt backup volumes (especially those that are network accessible) and exploit vulnerabilities in integrated backup platforms. They are no longer trying just to deny your access but erase the very means of recovery. If your backup environment isn't built with this evolving threat landscape in mind, it's at high risk of getting compromised. How can IT pros defend against this? In this guide, we'll uncover the weak strategies that lea...

Cybersecurity researchers have called attention to a new campaign that's actively exploiting a recently disclosed critical security flaw in Langflow to deliver the Flodrix botnet malware. "Attackers use the vulnerability to execute downloader scripts on compromised Langflow servers, which in turn fetch and install the Flodrix malware," Trend Micro researchers Aliakbar Zahravi, Ahmed Mohamed Ibrahim, Sunil Bharti, and Shubham Singh said in a technical report published today. The activity entails the exploitation of CVE-2025-3248 (CVSS score: 9.8), a missing authentication vulnerability in Langflow , a Python-based "visual framework" for building artificial intelligence (AI) applications. Successful exploitation of the flaw could enable unauthenticated attackers to execute arbitrary code via crafted HTTP requests. It was patched by Langflow in March 2025 with version 1.3.0. Last month, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) flagg...
