An investigation into the compromise of an Amazon Web Services (AWS)-hosted infrastructure has led to the discovery of a new GNU/Linux rootkit dubbed LinkPro , according to findings from Synacktiv. "This backdoor features functionalities relying on the installation of two eBPF [extended Berkeley Packet Filter] modules, on the one hand to conceal itself, and on the other hand to be remotely activated upon receiving a 'magic packet,'" security researcher Théo Letailleur said . The infection, per the French cybersecurity company, involved the attackers exploiting an exposed Jenkins server vulnerable to CVE-2024-23897 (CVSS score: 9.8) as the starting point, following which a malicious Docker Hub image named "kvlnt/vv" (now removed) was deployed on several Kubernetes clusters. The Docker image consists of a Kali Linux base along with a folder called "app" containing three files - start.sh, a shell script to start the SSH service and execute the...

Cybersecurity researchers have disclosed details of a new campaign that exploited a recently disclosed security flaw impacting Cisco IOS Software and IOS XE Software to deploy Linux rootkits on older, unprotected systems. The activity, codenamed Operation Zero Disco by Trend Micro, involves the weaponization of CVE-2025-20352 (CVSS score: 7.7), a stack overflow vulnerability in the Simple Network Management Protocol (SNMP) subsystem that could allow an authenticated, remote attacker to execute arbitrary code by sending crafted SNMP packets to a susceptible device. The intrusions have not been attributed to any known threat actor or group. The shortcoming was patched by Cisco late last month, but not before it was exploited as a zero-day in real-world attacks. "The operation primarily impacted Cisco 9400, 9300, and legacy 3750G series devices, with additional attempts to exploit a modified Telnet vulnerability (based on CVE-2017-3881 ) to enable memory access," research...

Penetration testing helps organizations ensure IT systems are secure, but it should never be treated in a one-size-fits-all approach. Traditional approaches can be rigid and cost your organization time and money – while producing inferior results.  The benefits of pen testing are clear. By empowering "white hat" hackers to attempt to breach your system using similar tools and techniques to an adversary, pen testing can provide reassurance that your IT set-up is secure. Perhaps more importantly, it can also flag areas for improvement.  As the UK's National Cyber Security Centre (NCSC) notes, it's comparable to a financial audit . "Your finance team tracks expenditure and income day to day. An audit by an external group ensures that your internal team's processes are sufficient." While the advantages are obvious, it's vital to understand the true cost of the process: indeed, the classic approach can often demand significant time and effort from your team. You need to get yo...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a critical security flaw impacting Adobe Experience Manager to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerability in question is CVE-2025-54253 (CVSS score: 10.0), a maximum-severity misconfiguration bug that could result in arbitrary code execution. According to Adobe, the shortcoming impacts Adobe Experience Manager (AEM) Forms on JEE versions 6.5.23.0 and earlier.

The flaw results from the dan...

U.S. cybersecurity company F5 on Wednesday disclosed that unidentified threat actors broke into its systems and stole files containing some of BIG-IP's source code and information related to undisclosed vulnerabilities in the product. It attributed the activity to a "highly sophisticated nation-state threat actor," adding the adversary maintained long-term, persistent access to its network. The company said it learned of the breach on August 9, 2025, per a Form 8-K filing with the U.S. Securities and Exchange Commission (SEC). F5 said it delayed the public disclosure at the request of the U.S. Department of Justice (DoJ). "We have taken extensive actions to contain the threat actor," it noted . "Since beginning these activities, we have not seen any new unauthorized activity, and we believe our containment efforts have been successful." F5 did not say for how long the threat actors had access to its BIG-IP product development environment, but em...

Microsoft on Tuesday released fixes for a whopping 183 security flaws spanning its products, including three vulnerabilities that have come under active exploitation in the wild, as the tech giant officially ended support for its Windows 10 operating system unless the PCs are enrolled in the Extended Security Updates ( ESU ) program.

These industrial devices are configured using a Windows utility called Sixnet IO Tool Kit, with a proprietary Sixnet "Universal" protocol used to interface and enable ...

Cybersecurity researchers have disclosed that a critical security flaw impacting ICTBroadcast, an autodialer software from ICT Innovations, has come under active exploitation in the wild. The vulnerability, assigned the CVE identifier CVE-2025-2611 (CVSS score: 9.3), relates to improper input validation that can result in unauthenticated remote code execution due to the fact that the call center application unsafely passes session cookie data to shell processing. This, in turn, allows an attacker to inject shell commands into a session cookie that can get executed in the vulnerable server. The security flaw affects ICTBroadcast versions 7.4 and below. "Attackers are leveraging the unauthenticated command injection in ICTBroadcast via the BROADCAST cookie to gain remote code execution," VulnCheck's Jacob Baines said in a Tuesday alert. "Approximately 200 online instances are exposed." The cybersecurity firm said that it detected in-the-wild exploitation o...

SAP has rolled out security fixes for 13 new security issues , including additional hardening for a maximum-severity bug in SAP NetWeaver AS Java that could result in arbitrary command execution. The vulnerability, tracked as CVE-2025-42944, carries a CVSS score of 10.0. It has been described as a case of insecure deserialization. "Due to a deserialization vulnerability in SAP NetWeaver, an unauthenticated attacker could exploit the system through the RMI-P4 module by submitting a malicious payload to an open port," according to a description of the flag in CVE.org.

Chipmaker AMD has released fixes to address a security flaw dubbed RMPocalypse that could be exploited to undermine confidential computing guarantees provided by Secure Encrypted Virtualization with Secure Nested Paging ( SEV-SNP ). The attack , per ETH Zürich researchers Benedict Schlüter and Shweta Shinde, exploits AMD's incomplete protections that make it possible to perform a single memory write to the Reverse Map Paging (RMP) table, a data structure that's used to store security metadata for all DRAM pages in the system. "The Reverse Map Table (RMP) is a structure that resides in DRAM and maps system physical addresses (sPAs) to guest physical addresses (gPAs)," according to AMD's specification documentation . "There is only one RMP for the entire system, which is configured using x86 model-specific registers (MSRs)." "The RMP also contains various security attributes of each that are managed by the hypervisor through hardware-mediated and...

Android devices from Google and Samsung have been found vulnerable to a side-channel attack that could be exploited to covertly steal two-factor authentication (2FA) codes, Google Maps timelines, and other sensitive data without the users' knowledge pixel-by-pixel. The attack has been codenamed Pixnapping by a group of academics from the University of California (Berkeley), University of Washington, University of California (San Diego), and Carnegie Mellon University. Pixnapping, at its core, is a pixel-stealing framework aimed at Android devices in a manner that bypasses browser mitigations and even siphons data from non-browser apps like Google Authenticator by taking advantage of Android APIs and a hardware side-channel, allowing a malicious app to weaponize the technique to capture 2FA codes in under 30 seconds. "Our key observation is that Android APIs enable an attacker to create an analog to [Paul] Stone-style attacks outside of the browser," the researchers...

Malware campaigns distributing the RondoDox botnet have expanded their targeting focus to exploit more than 50 vulnerabilities across over 30 vendors. The activity, described as akin to an "exploit shotgun" approach, has singled out a wide range of internet-exposed infrastructure, including routers, digital video recorders (DVRs), network video recorders (NVRs), CCTV systems, web servers, and various other network devices, according to Trend Micro. The cybersecurity company said it detected a RondoDox intrusion attempt on June 15, 2025, when the attackers exploited CVE-2023-1389 , a security flaw in TP-Link Archer routers that has come under active exploitation repeatedly since it was first disclosed in late 2022. RondoDox was first documented by Fortinet FortiGuard Labs back in July 2025, detailing attacks aimed at TBK digital video recorders (DVRs) and Four-Faith routers to enlist them in a botnet for carrying out distributed denial-of-service (DDoS) attacks agains...

Microsoft said it has revamped the Internet Explorer (IE) mode in its Edge browser after receiving "credible reports" in August 2025 that unknown threat actors were abusing the backward compatibility feature to gain unauthorized access to users' devices. "Threat actors were leveraging basic social engineering techniques alongside unpatched (0-day) exploits in Internet Explorer's JavaScript engine (Chakra) to gain access to victim devices," the Microsoft Browser Vulnerability Research team said in a report published last week. In the attack chain documented by the Windows maker, the threat actors have been found to trick unsuspecting users into visiting an seemingly legitimate website and then employ a flyout on the page to instruct them into reloading the page in IE mode. Once the page is reloaded, the attackers are said to have weaponized an unspecified exploit in the Chakra engine to obtain remote code execution. The infection sequence culminates w...

Oracle on Saturday issued a security alert warning of a fresh security flaw impacting its E-Business Suite that it said could allow unauthorized access to sensitive data. The vulnerability, tracked as CVE-2025-61884 , carries a CVSS score of 7.5, indicating high severity. It affects versions from 12.2.3 through 12.2.14. "Easily exploitable vulnerability allows an unauthenticated attacker with network access via HTTP to compromise Oracle Configurator," according to a description of the flaw in the NIST's National Vulnerability Database (NVD). "Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Configurator accessible data." In a standalone alert, Oracle said the flaw is remotely exploitable without requiring any authentication, making it crucial that users apply the update as soon as possible. The company, however, makes no mention of it being exploited in the wild. Oracle's Chi...

Cybersecurity company Huntress on Friday warned of "widespread compromise" of SonicWall SSL VPN devices to access multiple customer environments. "Threat actors are authenticating into multiple accounts rapidly across compromised devices," it said . "The speed and scale of these attacks imply that the attackers appear to control valid credentials rather than brute-forcing." A significant chunk of the activity is said to have commenced on October 4, 2025, with more than 100 SonicWall SSL VPN accounts across 16 customer accounts having been impacted. In the cases investigated by Huntress, authentications on the SonicWall devices originated from the IP address 202.155.8[.]73. The company noted that in some instances, the threat actors did not engage in further adversarial actions in the network and disconnected after a short period of time. However, in other cases, the attackers have been found conducting network scanning activity and attempting to access...

Threat actors are abusing Velociraptor, an open-source digital forensics and incident response (DFIR) tool, in connection with ransomware attacks likely orchestrated by Storm-2603 (aka CL-CRI-1040 or Gold Salem), which is known for deploying the Warlock and LockBit ransomware. The threat actor's use of the security utility was documented by Sophos last month. It's assessed that the attackers weaponized the on-premises SharePoint vulnerabilities known as ToolShell to obtain initial access and deliver an outdated version of Velociraptor (version 0.73.4.0) that's susceptible to a privilege escalation vulnerability ( CVE-2025-6264 ) to enable arbitrary command execution and endpoint takeover, per Cisco Talos . In the attack in mid-August 2025, the threat actors are said to have made attempts to escalate privileges by creating domain admin accounts and moving laterally within the compromised environment, as well as leveraging the access to run tools like Smbexec to remotely...

Fortra on Thursday revealed the results of its investigation into CVE-2025-10035 , a critical security flaw in GoAnywhere Managed File Transfer (MFT) that's assessed to have come under active exploitation since at least September 11, 2025. The company said it began its investigation on September 11 following a "potential vulnerability" reported by a customer, uncovering "potentially suspicious activity" related to the flaw.  That same day, Fortra said it contacted on-premises customers who were identified as having their GoAnywhere admin console accessible to the public internet and that it notified law enforcement authorities about the incident. A hotfix for versions 7.6.x, 7.7.x, and 7.8.x of the software was made available the next day, with full releases incorporating the patch – versions 7.6.3 and 7.8.4 – made available on September 15. Three days later, a CVE for the vulnerability was formally published, it added. "The scope of the risk of this...

Cybersecurity company Huntress said it has observed active in-the-wild exploitation of an unpatched security flaw impacting Gladinet CentreStack and TrioFox products. The zero-day vulnerability, tracked as CVE-2025-11371 (CVSS score: 6.1), is an unauthenticated local file inclusion bug that allows unintended disclosure of system files. It impacts all versions of the software prior to and including 16.7.10368.56560. Huntress said it first detected the activity on September 27, 2025, uncovering that three of its customers have been impacted so far. It's worth noting that both applications were previously affected by CVE-2025-30406 (CVSS score: 9.0), a case of hard-coded machine key that could allow a threat actor to perform remote code execution via a ViewState deserialization vulnerability. The vulnerability has since come under active exploitation. CVE-2025-11371, per Huntress, "allowed a threat actor to retrieve the machine key from the application Web.config fil...

Dozens of organizations may have been impacted following the zero-day exploitation of a security flaw in Oracle's E-Business Suite (EBS) software since August 9, 2025 , Google Threat Intelligence Group (GTIG) and Mandiant said in a new report released Thursday. "We're still assessing the scope of this incident , but we believe it affected dozens of organizations," John Hultquist, chief analyst of GTIG at Google Cloud, said in a statement shared with The Hacker News. "Some historic Cl0p data extortion campaigns have had hundreds of victims. Unfortunately, large-scale zero-day campaigns like this are becoming a regular feature of cybercrime." The activity, which bears some hallmarks associated with the Cl0p ransomware crew, is assessed to have fashioned together multiple distinct vulnerabilities, including a zero-day flaw tracked as CVE-2025-61882 (CVSS score: 9.8), to breach target networks and exfiltrate sensitive data. Google said it found evidence of ...
