Think your WAF has you covered? Think again. This holiday season, unmonitored JavaScript is a critical oversight allowing attackers to steal payment data while your WAF and intrusion detection systems see nothing. With the 2025 shopping season weeks away, visibility gaps must close now. Get the complete Holiday Season Security Playbook here . Bottom Line Up Front The 2024 holiday season saw major attacks on website code: the Polyfill.io breach hit 500,000+ websites, and September's Cisco Magecart attack targeted holiday shoppers. These attacks exploited third-party code and online store weaknesses during peak shopping, when attacks jumped 690% . For 2025: What security steps and monitoring should online retailers take now to prevent similar attacks while still using the third-party tools they need? As holiday shopping traffic increases, companies strengthen their servers and networks, but a critical weak spot remains unwatched: the browser environment where malicious code r...

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...

Cybersecurity researchers are calling attention to a new campaign that delivers the Astaroth banking trojan that employs GitHub as a backbone for its operations to stay resilient in the face of infrastructure takedowns. "Instead of relying solely on traditional command-and-control (C2) servers that can be taken down, these attackers are leveraging GitHub repositories to host malware configurations," McAfee Labs researchers Harshil Patel and Prabudh Chakravorty said in a report. "When law enforcement or security researchers shut down their C2 infrastructure, Astaroth simply pulls fresh configurations from GitHub and keeps running." The activity, per the cybersecurity company, is primarily focused on Brazil, although the banking malware is known to target various countries in Latin America, including Mexico, Uruguay, Argentina, Paraguay, Chile, Bolivia, Peru, Ecuador, Colombia, Venezuela, and Panama. This is not the first time Astaroth campaigns have trained t...

Cybersecurity researchers have disclosed details of a new Rust-based backdoor called ChaosBot that can allow operators to conduct reconnaissance and execute arbitrary commands on compromised hosts. "Threat actors leveraged compromised credentials that mapped to both Cisco VPN and an over-privileged Active Directory account named, 'serviceaccount,'" eSentire said in a technical report published last week. "Using the compromised account, they leveraged WMI to execute remote commands across systems in the network, facilitating the deployment and execution of ChaosBot." The Canadian cybersecurity company said it first detected the malware in late September 2025 within a financial services customer's environment. ChaosBot is noteworthy for its abuse of Discord for command-and-control (C2). It gets its name from a Discord profile maintained by the threat actor behind it, who goes by the online moniker "chaos_00019" and is responsible for issuin...

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...
