A previously undocumented China-aligned advanced persistent threat (APT) group named PlushDaemon has been linked to a supply chain attack targeting a South Korean virtual private network (VPN) provider in 2023, according to new findings from ESET. "The attackers replaced the legitimate installer with one that also deployed the group's signature implant that we have named SlowStepper – a feature-rich backdoor with a toolkit of more than 30 components," ESET researcher Facundo Muñoz said in a technical report shared with The Hacker News. PlushDaemon is assessed to be a China-nexus group that has been operational since at least 2019, targeting individuals and entities in China, Taiwan, Hong Kong, South Korea, the United States, and New Zealand. Central to its operations is a bespoke backdoor called SlowStepper, which is described as a large toolkit consisting of around 30 modules, programmed in C++, Python, and Go. Another crucial aspect of its attacks is the hijackin...

Over 57 distinct threat actors with ties to China, Iran, North Korea, and Russia have been observed using artificial intelligence (AI) technology powered by Google to further enable their malicious cyber and information operations. "Threat actors are experimenting with Gemini to enable their operations, finding productivity gains but not yet developing novel capabilities," Google Threat Intelligence Group (GTIG) said in a new report. "At present, they primarily use AI for research, troubleshooting code, and creating and localizing content." Government-backed attackers, otherwise known as Advanced Persistent Threat (APT) groups, have sought to use its tools to bolster multiple phases of the attack cycle, including coding and scripting tasks, payload development, gathering information about potential targets, researching publicly known vulnerabilities, and enabling post-compromise activities, such as defense evasion. Describing Iranian APT actors as the "he...

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...

Cybersecurity researchers have detailed a new campaign dubbed OneClik that leverages Microsoft's ClickOnce software deployment technology and bespoke Golang backdoors to compromise organizations within the energy, oil, and gas sectors. "The campaign exhibits characteristics aligned with Chinese-affiliated threat actors, though attribution remains cautious," Trellix researchers Nico Paulo Yturriaga and Pham Duy Phuc said in a technical write-up. "Its methods reflect a broader shift toward 'living-off-the-land' tactics, blending malicious operations within cloud and enterprise tooling to evade traditional detection mechanisms." The phishing attacks, in a nutshell, make use of a .NET-based loader called OneClikNet to deploy a sophisticated Go-based backdoor codenamed RunnerBeacon that's designed to communicate with attacker-controlled infrastructure that's obscured using Amazon Web Services (AWS) cloud services. ClickOnce is offered by Micro...

Top security firm RSA Security revealed on Thursday that it's been the victim of an "extremely sophisticated" hack. The company said in a note posted on its website that the intruders succeeded in stealing information related to the company's SecurID two-factor authentication products. SecurID adds an extra layer of protection to a login process by requiring users to enter a secret code number displayed on a keyfob, or in software, in addition to their password. The number is cryptographically generated and changes every 30 seconds. "While at this time we are confident that the information extracted does not enable a successful direct attack on any of our RSA SecurID customers," RSA wrote on its blog, "this information could potentially be used to reduce the effectiveness of a current two-factor authentication implementation as part of a broader attack. We are very actively communicating this situation to RSA customers and providing immediate steps for them to take to strengthen thei...

A previously undocumented China-aligned threat actor has been linked to a set of adversary-in-the-middle (AitM) attacks that hijack update requests from legitimate software to deliver a sophisticated implant named NSPX30. Slovak cybersecurity firm ESET is tracking the advanced persistent threat (APT) group under the name  Blackwood . It's said to be active since at least 2018. The NSPX30 implant has been observed deployed via the update mechanisms of known software such as Tencent QQ, WPS Office, and Sogou Pinyin, with the attacks targeting Chinese and Japanese manufacturing, trading, and engineering companies as well as individuals located in China, Japan, and the U.K. "NSPX30 is a multistage implant that includes several components such as a dropper, an installer, loaders, an orchestrator, and a backdoor," security researcher Facundo Muñoz  said . "Both of the latter two have their own sets of plugins." "The implant was designed around the attackers...

The Chinese state-sponsored threat actor known as Mustang Panda has been observed employing a novel technique to evade detection and maintain control over infected systems. This involves the use of a legitimate Microsoft Windows utility called Microsoft Application Virtualization Injector (MAVInject.exe) to inject the threat actor's malicious payload into an external process, waitfor.exe, whenever ESET antivirus application is detected running, Trend Micro said in a new analysis. "The attack involves dropping multiple files, including legitimate executables and malicious components, and deploying a decoy PDF to distract the victim," security researchers Nathaniel Morales and Nick Dai noted. "Additionally, Earth Preta utilizes Setup Factory, an installer builder for Windows software, to drop and execute the payload; this enables them to evade detection and maintain persistence in compromised systems." The starting point of the attack sequence is an execu...

Ever wonder what happens when attackers don't break the rules—they just follow them better than we do? When systems work exactly as they're built to, but that "by design" behavior quietly opens the door to risk? This week brings stories that make you stop and rethink what's truly under control. It's not always about a broken firewall or missed patch—it's about the small choices, default settings, and shortcuts that feel harmless until they're not. The real surprise?

Threat actors with ties to North Korea have been observed targeting Web3 and cryptocurrency-related businesses with malware written in the Nim programming language, underscoring a constant evolution of their tactics. "Unusually for macOS malware, the threat actors employ a process injection technique and remote communications via wss, the TLS-encrypted version of the WebSocket protocol," SentinelOne researchers Phil Stokes and Raffaele Sabato said in a report shared with The Hacker News. "A novel persistence mechanism takes advantage of SIGINT/SIGTERM signal handlers to install persistence when the malware is terminated or the system rebooted." The cybersecurity company is tracking the malware components collectively under the name NimDoor. It's worth noting that some aspects of the campaign were previously documented by Huntabil.IT and later by Huntress and Validin , but with differences in the payloads deployed. The attack chains involve social enginee...

A suspected Chinese-nexus hacking group exploited a  recently disclosed zero-day flaw  in Barracuda Networks Email Security Gateway (ESG) appliances to breach government, military, defense and aerospace, high-tech industry, and telecom sectors as part of a global espionage campaign. Mandiant, which is tracking the activity under the name  UNC4841 , described the threat actor as "highly responsive to defensive efforts" and capable of actively tweaking their modus operandi to maintain persistent access to targets. "UNC4841 deployed new and novel malware designed to maintain presence at a small subset of high priority targets that it compromised either before the patch was released, or shortly following Barracuda's remediation guidance," the Google-owned threat intelligence firm  said  in a new technical report published today. Almost a third of the identified affected organizations are government agencies. Interestingly enough, some of the earliest compromises...
