Threat actors are continuing to exploit a critical, now-patched security flaw impacting FortiClient Endpoint Management Server (EMS) deployments to deliver credential-stealing malware. "The campaign abused trusted endpoint management infrastructure to deliver malware across managed endpoints," Arctic Wolf said . "Threat actors disguised the credential stealer payload as a Fortinet endpoint update, silently executing the malicious executable through PowerShell." The activity, observed by the cybersecurity company in May 2026, involves the exploitation of CVE-2026-35616 (CVSS score: 9.1), a critical pre-authentication API access bypass leading to privilege escalation. The issue was addressed by Fortinet in FortiClient EMS 7.4.7 and later. A successful compromise is followed by the threat actor taking steps to modify configurations to defer firmware upgrade reminders, as well as modifying a Remote Access Profile configuration and endpoint policy to insert a mal...

Every time you think the industry has finally stopped doing some reckless, low-effort crap, somebody spins up a fresh box full of sketchy loaders, fake installers, recycled social-engineering bait, and enough exposed infrastructure to make you wonder if prod is just a public beta now - meanwhile some researcher casually drops a technique that turns a "minor" foothold into total account compromise because apparently six digits and blind trust were all that stood between your vault and getting absolutely pwned. Cool. Great. Love that for us. Then there's the supply chain mess... signed binaries, poisoned updates, legit tooling getting hijacked like it's still 2017, plus a few reports this week that feel less like advanced tradecraft and more like watching skiddies discover low-hanging fruit with enterprise branding slapped on top. The weird part isn't that it works. The weird part is how damn easy it still is. Anyway. Grab caffeine. Let's get into it. ...

A new campaign orchestrated by a previously undocumented threat actor has targeted cryptocurrency organizations with an aim to facilitate digital asset theft using recruitment-themed social engineering and bespoke macOS malware. "These campaigns leveraged sophisticated social engineering techniques, custom macOS malware, and deep targeting of CI/CD infrastructure," Wiz researchers Shira Ayal, Eden Abergil, Andre Maccarone, Yuval Dan, and Benjamin Read said . "The used methods enabled the threat actor to move laterally from compromised employee laptops to code distribution systems and development infrastructure." The Google-owned cloud security company is tracking the activity under the moniker JINX-0164 . The threat actor is assessed to be active since at least mid-2025 and motivated by financial gain, targeting developers through recruitment-themed and other social engineering techniques to siphon cryptocurrencies. In at least one case, the adversary is said t...

Latin America and Europe become the target of two banking trojan campaigns that are designed to infect Windows and Android devices with Grandoreiro and BTMOB malware, respectively. That's according to new findings from WatchGuard and ESET, which have observed the two malware families being used to single out companies in Spain, Portugal, and Mexico, as well as mobile users in Brazil. The Grandoreiro campaign "uses the DLL Side-Loading technique abusing four different software, targeting banks in Portugal," WatchGuard researcher Euler Neto said . Active since 2016, Grandoreiro is an actively evolving banking malware that's capable of stealing credentials associated with thousands of financial institutions across 45 countries and territories. It's typically distributed via phishing emails, instructing recipients to click on sketchy links. Despite some arrests and attempts by Brazilian authorities to dismantle its infrastructure in early 2024, the malware h...

Cybersecurity researchers have discovered a new malicious package on the npm registry that comes with information stealing capabilities. According to OX Security, the package, named " mouse5212-super-formatter ," is designed to upload files from "/mnt/user-data," a dedicated directory used by Anthropic's Claude artificial intelligence (AI) tool to handle uploads and outputs in the background. The activity has been codenamed Malware-Slop . "By analyzing the malware, it turns out that the script presents itself as an internal 'archive deployment sync' utility that validates or initializes a GitHub repository, captures a lightweight 'network status' snapshot, and then performs a structured synchronization of local workspace files into a remote tracking tree," researchers Moshe Siman Tov Bustan and Nir Zadok said . In reality, however, it authenticates to GitHub during the postinstall stage, either using a GitHub access token found i...
