SharePoint Flaw Initially Listed as Spoofing by Microsoft Enables Authenticated RCE

A SharePoint Server vulnerability that Microsoft initially classified as a spoofing flaw with a CVSS score of 6.5 actually enables authenticated remote code execution, according to full technical details published today by Viettel Cyber Security researcher Dinh Ho Anh Khoa. The flaw, CVE-2026-65660 , affects SharePoint Server 2016, 2019, and Subscription Edition. Patches have been available since the  August 11 security updates , and the National Vulnerability Database scores it 8.8. Microsoft's advisory  describes CVE-2026-65660 as allowing an authorized attacker to perform spoofing and assigns no impact to integrity or availability. The CVE record that Microsoft publishes separately, updated on September 11, titles the same flaw a remote code execution vulnerability and says it allows an authorized attacker to execute code. Both records assign CWE-94, a code-injection weakness. Defenders who triaged CVE-2026-65660 based on the advisory saw a moderate spoofi...

Malicious npm Package indexed-btree Hid Its Loader in Runtime Code Before Removal

A malicious npm package named "indexed-btree" has been observed hiding its malicious behavior within application code rather than using lifecycle scripts, indicating that threat actors are likely shifting tactics in response to recent security controls . "Indexed-btree is a malicious npm package mimicking the legit sorted-btree package, an ordinary B-tree/indexing utility," Checkmarx said . "Unlike the common attacks we've seen in the supply chain space, this package does not rely on preinstall / postinstall at all. Instead, it runs entirely from application code at runtime." The package and the associated GitHub repository are no longer available for download from npm. However, statistics show the package was first uploaded to the registry on June 18, 2026, by an npm user named " charlessadler25 ," amassing millions of downloads in a short span of time . To make matters worse, the campaign may have generated illicit profits for the...

SideCopy Broadens India Targeting to Academia With ReverseRAT Spear-Phishing

The threat actor known as SideCopy has been observed using spear-phishing lures to target academic institutions in India, expanding their strategic focus beyond government entities. "SideCopy campaign operations typically initiate through spear-phishing campaigns that leverage the abuse of mshta.exe to execute malicious scripts and circumvent standard security protocols," Trellix researchers Boggavarapu R S S Srinivas Gupta and Ravishankar N C said in a technical report. "This delivery mechanism facilitates the deployment of a remote access trojan (RAT), which serves as the central pillar of their offensive infrastructure." Active since at least 2019, SideCopy (aka TAG-140) is an advanced persistent threat (APT) group that originates from Pakistan, and shares overlaps with the Transparent Tribe cluster. Historically, the threat actor has primarily targeted Indian defense forces and government officials. In a report published in June 2026, Seqrite Labs a...

One Hidden Meta Muse Setting Could Let Attackers Turn the AI Assistant Into a Backdoor

Malware already running on a Mac can quietly take over Meta's Muse assistant and use the broad access its owner granted the app, security researcher Patrick Wardle has shown in a  proof-of-concept  released on September 21. It works by changing a hidden setting so that when the user taps the microphone and dictates a prompt, the words go to the attacker instead of Meta. The flaw is in the Mac version of Muse, and it only works if an attacker can already run code as the logged-in user. It cannot break into a Mac on its own. But Wardle told The Hacker News that a remote attacker could hijack Muse and steal its token through a ClickFix trick, which fools the user into running a single command with nothing to download or install. Muse is the personal AI agent Meta  launched this month  in the United States. Once a user turns it on, it can work across their files, email, messages, calendar, shopping and smart-home apps, using whatever access the person chooses to g...

WordPress Comment2Shell Flaw Can Turn Anonymous Comment XSS Into RCE via Admin Session

A new flaw in WordPress core let an anonymous visitor leave a comment that planted a hidden script on the page. If a logged-in administrator later opened that page, the script could run code on the site's server. WordPress fixed the flaw, tracked as  CVE-2026-93485  and dubbed " Comment2Shell ," on September 17 in  version 7.1.1  and told site owners to update right away. The researcher who reported it said he is not aware of it being used in attacks, and it is not on the U.S. government's list of actively exploited software flaws. Patchstack, the company that assigned that identifier, rated the flaw 7.1 out of 10 on the CVSS scale. WordPress checks a comment for dangerous HTML when it is saved, then reformats it when the page is shown, and the flaw sat in the gap between those two steps. Rafie Muhammad, the security researcher who reported the bug, laid out the full chain in  a write-up  on September 21. The trick was a line break placed inside th...

Zyxel and Veeam Flaws Under Active Exploitation With Command and SYSTEM Access

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a now-patched security flaw impacting Zyxel GS1900 series switches to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2026-7273 (CVSS score: 8.8), is a stack-based buffer overflow vulnerability that could result in arbitrary operating system (OS) command execution. "A stack-based buffer overflow vulnerability in the CGI program of the Zyxel GS1900 series switch firmware could allow a LAN-based, unauthenticated attacker to exploit the flaw and potentially execute OS commands via a crafted HTTP request," Zyxel said in an advisory released in June 2026.  The issue has been addressed in the following versions -

Fake LastPass Authenticator Installer Abuses Microsoft-Signed Driver to Kill Antivirus and EDR

A fake LastPass Authenticator installer offered on GitHub installs a Windows kernel driver that shuts off antivirus and other security software before a password stealer runs if a victim downloads and runs it, researchers at LastPass and Delphos Labs said on September 17. Microsoft's own hardware-compatibility program signs the driver, scored zero detections on VirusTotal when researchers checked it in August, and was not on Microsoft's list of blocked drivers. LastPass says none of its own systems, services, or customer vaults were touched, and that the attackers only borrowed its name. The lure is a fake GitHub page (github.com/LastPass-Authenticator) that ranks in search results for terms like "LastPass Authenticator download" and looks like a real LastPass product page. Clicking the download button sends the visitor through several GitHub pages to an attacker server, which serves a large ZIP file. The real LastPass Authenticator comes from lastpass.com and ...

Contagious Interview Campaign Compromises 30,000 Devices, Steals $10.71M in Crypto

The North Korean threat actors behind the Contagious Interview campaign have compromised at least 30,000 devices located in more than 100 countries and siphoned funds or account credentials from over 7,000 cryptocurrency wallets, according to a new joint cybersecurity advisory . The primary targets of the campaign are individual web designers, engineers, and specialists in cryptocurrency, blockchain, and Web3 technologies. In all, the threat actors are estimated to have plundered at least $10.71 million worth of cryptocurrency from victims. The alert comes courtesy of cybersecurity and intelligence agencies from Japan, the U.S., Australia, and Germany. The activity is tracked by the broader cybersecurity community under the monikers CL-STA-0240, DeceptiveDevelopment, DEV#POPPER, Famous Chollima, Gwisin Gang, PurpleBravo, Tenacious Pungsan, UNC5342, Void Dokkaebi, and WaterPlum. The cyber threat group "conducts cyber attacks by infiltrating unsuspecting job seekers' com...
