The Russia-linked state-sponsored threat actor tracked as APT28 (aka BlueDelta, Fancy Bear, and Forest Blizzard) has been attributed to attacks targeting two member states of the North Atlantic Treaty Organization (NATO). The Symantec Threat Hunter Team, which is tracking the activity cluster under the moniker Swallowtail , involved the use of a backdoor called HOOKEDGE and a previously undocumented loader that is designed to decrypt and run an encrypted payload in memory by using a cryptographic key that's supplied at runtime. Targets of the activity included a law enforcement agency, a naval shipbuilder, and a manufacturer of military aircraft engines – entities that hold information that could be of use to a foreign intelligence agency, the Broadcom-owned threat intelligence unit said. "During one attack against the naval shipbuilder, operators returned to a compromised host repeatedly over the course of a week in what appeared to be hands-on-keyboard activity,...

An attacker used a contributor's GitHub account to replace the download archives on five existing releases of OVHcloud's command-line tool on Monday, October 19. The account had been hijacked, and the new files were a build designed to steal secrets stored on the disk of any machine that runs it, the cloud provider says. They were live on GitHub for up to 94 minutes, from 12:47 to 14:21 UTC, and reached only people who installed or updated the OVHcloud CLI during that window, via a path that checks for no hash, on macOS, Linux x86_64 or arm64, or Windows x86_64. OVHcloud deleted the swapped archives and published a clean  v0.16.0  that evening as an immutable release, whose files GitHub will not let anyone change. The source code, the release tag, and the company's build pipeline were not touched: the bad build was a plain go build of a later commit, uploaded straight onto releases published between April and September. Who Was Exposed On v0.15.0, the attac...

Siemens has addressed a DLL sideloading vulnerability impacting Siemens Software Center that it said has been exploited in ClickFix attacks. The high-severity vulnerability, tracked as CVE-2026-110936 (CVSS v4 score: 8.4), could allow an attacker to place a specially-crafted DLL in a directory the application searches, resulting in execution of malicious code with the same privileges as the affected service. "The affected application loads dynamic-link libraries (DLLs) from an uncontrolled search path," Siemens said in an advisory. "This could allow an authenticated local attacker to place a specially crafted DLL in a directory that the application searches, leading to arbitrary code execution with the privileges of the affected application." The issue has been patched in version 4.0.9.8. Huntress Labs researcher Jose Oregon has been credited with discovering and reporting the shortcoming. In a separate alert, Siemens said attackers have abused a genuine ...

Cybersecurity researchers have disclosed details of a ClickFix delivery platform called ROMULUS that's being used to distribute malware such as Legion Loader. According to Forescout Research - Vedere Labs, ROMULUS is akin to a malware delivery service that employs ClickFix-style lures on bogus landing pages to trick unsuspecting users into running malicious commands and infecting their own machines. "ROMULUS may be a privately operated panel, a commercial cybercriminal delivery service, an affiliate framework, or software that has been copied between operators," security researcher Sai Molige said in an analysis. The cybersecurity company said it identified six IP addresses running ROMULUS -

Threat actors have begun to exploit a chain of vulnerabilities in Plex Media Server to deploy cryptocurrency miners and reverse proxy software, a day after a proof-of-concept (PoC) went public. According to a researcher who goes by the online alias boredhackerblog , the exploitation activity involves chaining four different vulnerabilities, collectively called Plex2Shell . The vulnerabilities are below - CVE-2026-96652 (CVSS score: 5.3) - An unauthenticated server-side request forgery (SSRF) stemming via the "/player/timeline" endpoint by taking advantage of the fact that the "protocol" parameter is inserted into a programmatically-constructed player URL with no validation, allowing an attacker to force the Plex server to POST to a destination of their choice. CVE-2026-96654 (CVSS score: 6.9) - An improper neutralization of URL values included in the "searchOne" endpoint that could allow an attacker to call other plugins' functions and...
