A now-patched critical security flaw in the Wazur Server is being exploited by threat actors to drop two different Mirai botnet variants and use them to conduct distributed denial-of-service (DDoS) attacks. Akamai, which first discovered the exploitation efforts in late March 2025, said the malicious campaign targets CVE-2025-24016 (CVSS score: 9.9), an unsafe deserialization vulnerability that allows for remote code execution on Wazuh servers. The security defect , which affects all versions of the server software including and above 4.4.0, was addressed in February 2025 with the release of 4.9.1. A proof-of-concept (PoC) exploit was publicly disclosed around the same time the patches were released. The problem is rooted in the Wazuh API, where parameters in the DistributedAPI are serialized as JSON and deserialized using "as_wazuh_object" in the framework/wazuh/core/cluster/common.py file. A threat actor could weaponize the vulnerability by injecting malicious JSON...

Behind every security alert is a bigger story. Sometimes it's a system being tested. Sometimes it's trust being lost in quiet ways—through delays, odd behavior, or subtle gaps in control. This week, we're looking beyond the surface to spot what really matters. Whether it's poor design, hidden access, or silent misuse, knowing where to look can make all the difference. If you're responsible for protecting systems, data, or people—these updates aren't optional. They're essential. These stories reveal how attackers think—and where we're still leaving doors open. ⚡ Threat of the Week Google Releases Patches for Actively Exploited Chrome 0-Day — Google has released Google Chrome versions 137.0.7151.68/.69 for Windows and macOS, and version 137.0.7151.68 for Linux to address a high-severity out-of-bounds read and write vulnerability in the V8 JavaScript and WebAssembly engine that it said has been exploited in the wild. Google credited Clement Lecigne and Benoît Sevens of Google T...

OpenAI has revealed that it banned a set of ChatGPT accounts that were likely operated by Russian-speaking threat actors and two Chinese nation-state hacking groups to assist with malware development, social media automation, and research about U.S. satellite communications technologies, among other things. "The [Russian-speaking] actor used our models to assist with developing and refining Windows malware, debugging code across multiple languages, and setting up their command-and-control infrastructure," OpenAI said in its threat intelligence report. "The actor demonstrated knowledge of Windows internals and exhibited some operational security behaviors." The Go-based malware campaign has been codenamed ScopeCreep by the artificial intelligence (AI) company. There is no evidence that the activity was widespread in nature. The threat actor, per OpenAI, used temporary email accounts to sign up for ChatGPT, using each of the created accounts to have one conversat...

Cybersecurity researchers have flagged a supply chain attack targeting over a dozen packages associated with GlueStack to deliver malware. The malware, introduced via a change to "lib/commonjs/index.js," allows an attacker to run shell commands, take screenshots, and upload files to infected machines, Aikido Security told The Hacker News, stating these packages collectively account for nearly 1 million weekly downloads. The unauthorized access could then be used to perform various follow-on actions like mining cryptocurrency, stealing sensitive information, and even shutting down services. Aikido said the first package compromise was detected on June 6, 2025, at 9:33 p.m. GMT.  The list of the impacted packages and the affected versions is below - @gluestack-ui/utils version 0.1.16 (101 Downloads) @gluestack-ui/utils version 0.1.17 (176 Downloads) @react-native-aria/button version 0.2.11 (174 Downloads) @react-native-aria/checkbox version 0.2.11 (577 Downloads) @re...

Cybersecurity researchers have shed light on a new campaign targeting Brazilian users since the start of 2025 to infect users with a malicious extension for Chromium-based web browsers and siphon user authentication data. "Some of the phishing emails were sent from the servers of compromised companies, increasing the chances of a successful attack," Positive Technologies security researcher Klimentiy Galkin said in a report. "The attackers used a malicious extension for Google Chrome, Microsoft Edge, and Brave browsers, as well as Mesh Agent and PDQ Connect Agent." The Russian cybersecurity company, which is tracking the activity under the name Operation Phantom Enigma , said the malicious extension was downloaded 722 times from across Brazil, Colombia, the Czech Republic, Mexico, Russia, and Vietnam, among others. As many as 70 unique victim companies have been identified. Some aspects of the campaign were disclosed in early April by a researcher who goes by th...

Cybersecurity researchers are alerting to a new malware campaign that employs the ClickFix social engineering tactic to trick users into downloading an information stealer malware known as Atomic macOS Stealer ( AMOS ) on Apple macOS systems. The campaign, according to CloudSEK, has been found to leverage typosquat domains mimicking U.S.-based telecom provider Spectrum. "macOS users are served a malicious shell script designed to steal system passwords and download an AMOS variant for further exploitation," security researcher Koushik Pal said in a report published this week. "The script uses native macOS commands to harvest credentials, bypass security mechanisms, and execute malicious binaries." It's believed that the activity is the work of Russian-speaking cybercriminals owing to the presence of Russian language comments in the malware's source code. The starting point of the attack is a web page that impersonates Spectrum ("panel-spectrum[....

A critical infrastructure entity within Ukraine was targeted by a previously unseen data wiper malware named PathWiper, according to new findings from Cisco Talos. "The attack was instrumented via a legitimate endpoint administration framework, indicating that the attackers likely had access to the administrative console, that was then used to issue malicious commands and deploy PathWiper across connected endpoints," researchers Jacob Finn, Dmytro Korzhevin, and Asheer Malhotra said in an analysis published Thursday. The attack is assessed to be the work of a Russia-nexus advanced persistent threat (APT) actor based on the tradecraft observed and the overlapping capabilities with destructive malware used in attacks against Ukraine. Talos said the commands issued by the administrative tool's console were received by its client running on the victim endpoints and then executed as a batch (BAT) file. The BAT file, in turn, consisted of a command to run a malicious Visu...

The threat actor known as Bitter has been assessed to be a state-backed hacking group that's tasked with gathering intelligence that aligns with the interests of the Indian government. That's according to new findings jointly published by Proofpoint and Threatray in an exhaustive two-part analysis. "Their diverse toolset shows consistent coding patterns across malware families, particularly in system information gathering and string obfuscation," researchers Abdallah Elshinbary, Jonas Wagner, Nick Attfield, and Konstantin Klinger said. Bitter, also known as APT-C-08, APT-Q-37, Hazy Tiger, Orange Yali, T-APT-17, and TA397, has a history of focusing primarily on South Asian entities , with select intrusions also targeting China, Saudi Arabia, and South America. In December 2024, evidence emerged of the threat actor's targeting of Turkey using malware families such as WmRAT and MiyaRAT, indicating a gradual geographical expansion. Stating that Bitter fr...

An Iran-aligned hacking group has been attributed to a new set of cyber attacks targeting Kurdish and Iraqi government officials in early 2024. The activity is tied to a threat group ESET tracks as BladedFeline , which is assessed with medium confidence to be a sub-cluster within OilRig , a known Iranian nation-state cyber actor. It's said to be active since September 2017, when it targeted officials associated with the Kurdistan Regional Government (KRG). "This group develops malware for maintaining and expanding access within organizations in Iraq and the KRG," the Slovak cybersecurity company said in a technical report shared with The Hacker News. "BladedFeline has worked consistently to maintain illicit access to Kurdish diplomatic officials, while simultaneously exploiting a regional telecommunications provider in Uzbekistan, and developing and maintaining access to officials in the government of Iraq." BladedFeline was first documented by ESET in Ma...

Google has disclosed details of a financially motivated threat cluster that it said "specializes" in voice phishing (aka vishing ) campaigns designed to breach organizations' Salesforce instances for large-scale data theft and subsequent extortion. The tech giant's threat intelligence team is tracking the activity under the moniker UNC6040 , which it said exhibits characteristics that align with threat groups with ties to an online cybercrime collective known as The Com . "Over the past several months, UNC6040 has demonstrated repeated success in breaching networks by having its operators impersonate IT support personnel in convincing telephone-based social engineering engagements," the company said in a report shared with The Hacker News. This approach, Google's Threat Intelligence Group (GTIG) added, has had the benefit of tricking English-speaking employees into performing actions that give the threat actors access or lead to the sharing of valua...

Threat hunters are calling attention to a new variant of a remote access trojan (RAT) called Chaos RAT that has been used in recent attacks targeting Windows and Linux systems. According to findings from Acronis, the malware artifact may have been distributed by tricking victims into downloading a network troubleshooting utility for Linux environments. "Chaos RAT is an open-source RAT written in Golang, offering cross-platform support for both Windows and Linux systems," security researchers Santiago Pontiroli, Gabor Molnar, and Kirill Antonenko said in a report shared with The Hacker News. "Inspired by popular frameworks such as Cobalt Strike and Sliver, Chaos RAT provides an administrative panel where users can build payloads, establish sessions, and control compromised machines." While work on the "remote administration tool" started way back in 2017, it did not attract attention until December 2022 , when it was put to use in a malicious campaig...

Several malicious packages have been uncovered across the npm, Python, and Ruby package repositories that drain funds from cryptocurrency wallets, erase entire codebases after installation, and exfiltrate Telegram API tokens, once again demonstrating the variety of supply chain threats lurking in open-source ecosystems. The findings come from multiple reports published by Checkmarx, ReversingLabs, Safety, and Socket in recent weeks. The list of identified packages across these platforms are listed below - Socket noted that the two malicious gems were published by a threat actor under the aliases Bùi nam, buidanhnam, and si_mobile merely days after Vietnam ordered a nationwide ban on the Telegram messaging app late last month for allegedly not cooperating with the government to tackle illicit activities related to fraud, drug trafficking, and terrorism. "These gems silently exfiltrate all data sent to the Telegram API by redirecting traffic through a command-and-control (C2...
