Cybersecurity researchers are calling attention to a new campaign where threat actors are abusing FortiGate Next-Generation Firewall (NGFW) appliances as entry points to breach victim networks.  The activity involves the exploitation of recently disclosed security vulnerabilities or weak credentials to extract configuration files containing service account credentials and network topology information, SentinelOne said in a report published today. The security outfit said the campaign has singled out environments tied to healthcare, government, and managed service providers. "FortiGate network appliances have considerable access to the environments they were installed to protect," security researchers Alex Delamotte, Stephen Bromfield, Mary Braden Murphy, and Amey Patne said . "In many configurations, this includes service accounts which are connected to the authentication infrastructure, such as Active Directory (AD) and Lightweight Directory Access Protocol (LDAP)....

Cybersecurity researchers have discovered a new malware called KadNap that's primarily targeting Asus routers to enlist them into a botnet for proxying malicious traffic. The malware, first detected in the wild in August 2025, has expanded to over 14,000 infected devices, with more than 60% of victims located in the U.S., according to the Black Lotus Labs team at Lumen. A lesser number of infections have been detected in Taiwan, Hong Kong, Russia, the U.K., Australia, Brazil, France, Italy, and Spain. "KadNap employs a custom version of the Kademlia Distributed Hash Table ( DHT ) protocol, which is used to conceal the IP address of their infrastructure within a peer-to-peer system to evade traditional network monitoring," the cybersecurity company said in a report shared with The Hacker News. Compromised nodes in the network leverage the DHT protocol to locate and connect with a command-and-control (C2) server, thereby making it resilient to detection and disrupt...

The Russian state-sponsored hacking group tracked as APT28 has been observed using a pair of implants dubbed BEARDSHELL and COVENANT to facilitate long‑term surveillance of Ukrainian military personnel. The two malware families have been put to use since April 2024, ESET said in a new report shared with The Hacker News. APT28, also tracked as Blue Athena, BlueDelta, Fancy Bear, Fighting Ursa, Forest Blizzard (formerly Strontium), FROZENLAKE, Iron Twilight, ITG05, Pawn Storm, Sednit, Sofacy, and TA422, is a nation-state actor affiliated with Unit 26165 of the Russian Federation's military intelligence agency GRU. The threat actor's malware arsenal consists of tools like BEARDSHELL and COVENANT, along with another program codenamed SLIMAGENT that's capable of logging keystrokes, capturing screenshots, and collecting clipboard data. SLIMAGENT was first publicly documented by the Computer Emergency Response Team of Ukraine (CERT-UA) in June 2025. SLIMAGENT, per the Slo...

Cybersecurity researchers have discovered a malicious npm package that masquerades as an OpenClaw installer to deploy a remote access trojan (RAT) and steal sensitive data from compromised hosts. The package, named " @openclaw-ai/openclawai ," was uploaded to the registry by a user named "openclaw-ai" on March 3, 2026. It has been downloaded 178 times to date. The library is still available for download as of writing. JFrog, which discovered the package, said it's designed to steal system credentials, browser data, crypto wallets, SSH keys, Apple Keychain databases, and iMessage history, as well as install a persistent RAT with remote access capabilities, SOCKS5 proxy, and live browser session cloning. It's tracking the activity under the name GhostClaw. "The attack is notable for its broad data collection, its use of social engineering to harvest the victim's system password, and the sophistication of its persistence and C2 [command-and-contro...

Another week in cybersecurity. Another week of "you've got to be kidding me." Attackers were busy. Defenders were busy. And somewhere in the middle, a whole lot of people had a very bad Monday morning. That's kind of just how it goes now. The good news? There were some actual wins this week. Real ones. The kind where the good guys showed up, did the work, and made a dent. It doesn't always happen, so when it does, it's worth noting. The bad news? For every win, there's a fresh headache waiting right behind it. New tricks, old tricks dressed up in new clothes, and a few things that'll make you want to go touch grass and never log back in. But you will. We all do. So here's everything that mattered this week — the wins, the warnings, and the stuff you really shouldn't ignore. ⚡ Threat of the Week Tycoon 2FA and LeakBase Operations Dismantled — The infrastructure hosting the Tycoon2FA service, which Europol said was among the largest advers...
