Your Cloud Security Checklist Doesn't Work the Way You Think It Does

Sep 07, 2026Cloud Security / Data Security

If managing security across multiple cloud providers wasn't hard enough, each one fails in a different way. For the 2026 Cloud Security Index , Intruder analyzed misconfiguration data from 3,000 organizations across AWS, Azure, and Google Cloud and found that risk profiles across providers have almost nothing in common. Here’s what the data looks like. How risk differs across cloud providers Intruder grouped every misconfiguration into one of six categories: weak identity and access management (IAM), missing logging, misconfigured services, permissive firewalls, exposed services, and weak encryption. For each category, they compared how many accounts had at least one issue in it across the three providers. Weak IAM controls and missing logging are near-universal, affecting between 80% and 98% of accounts regardless of provider. The other four categories are where things diverge: Exposed services: AWS (76%) , Azure (64%) , Google Cloud (8%) Permissive firewalls: AWS...

Rogue ScreenConnect Clients Spread Four-Stage VBScript Chain to Newly Connected Hosts

Sep 07, 2026Malware / Vulnerability

Cybersecurity researchers have disclosed details of worm-like activity that abuses ConnectWise ScreenConnect to distribute a malicious Visual Basic Script (VBScript) payload to newly connected systems. According to Huntress , three unrelated incidents have been found to use diverse initial access methods, namely a Quick Assist tech-support scam, a phishing-delivered MSI installer, and a fake Geek Squad refund form lure, to activate a four-stage VBScript chain that leads to rogue ScreenConnect installations. However, once the ScreenConnect instances were installed, the cybersecurity company said it observed the clients repeatedly spawning "wscript.exe" to execute VBScripts named 1.vbs, 2.vbs, 3.vbs, and 4.vbs. The incidents were observed in August 2026. The details of the three attacks are below - A social engineering attack that persuaded a user into executing Quick Assist as part of a tech support scam, after which a rogue ScreenConnect remote access client was d...

Telerik UI Padding-Oracle Bug Chained to Unauthenticated RCE — Public Exploit Released

Sep 07, 2026Vulnerability / Web Security

A TantoSec proof-of-concept turns an AES-CBC "padding oracle" in Telerik UI for ASP.NET AJAX into unauthenticated remote code execution — but only against applications in a specific non-default configuration, and Progress patched the chain in July. There are no confirmed reports of exploitation in the wild. Security firm TantoSec has published a working exploit chain targeting vulnerabilities in Telerik UI for ASP.NET AJAX that can allow an unauthenticated attacker to execute remote code on the server hosting a vulnerable application. Progress Software patched the flaws in July, and exploitation requires a non-default configuration — but the release pairs a detailed write-up with a ready-to-run tool and two payloads, putting a complete attack path in public hands for the first time. The underlying flaws are not new. Progress shipped the fix in version 2026.2.708 (2026 Q2 SP1) on July 8 and published the CVEs and advisory on July 22. What changed on September 7 is t...

N-able Issues Fourth N-central Hotfix in Five Weeks for Unauthenticated RCE Flaw

Sep 07, 2026Vulnerability / Enterprise Security

Every on-premises N-central build below 2026.3.1.14 — including servers updated to Hotfix 3 a day earlier — needs Hotfix 4. N-able's incident notice says the flaw has been exploited in the wild; its release notes say that is unconfirmed. N-able has released its  fourth hotfix  in five weeks for the N-central remote monitoring and management (RMM) platform, this time for a maximum-severity vulnerability that could allow remote code execution on the N-central server without authentication. The company's own communications disagree on whether the flaw has already been exploited. The vulnerability, tracked as  CVE-2026-86218 , carries a CVSS 4.0 score of 10.0, assigned by N-able as the CVE Numbering Authority, and is classed as a static code injection weakness (CWE-96). It affects every N-central build before 2026.3.1.14, the build shipped as 2026.3 Hotfix 4 in the early hours of September 6 (UTC). That includes servers already updated to  Hotfix 3  (2026.3...

JSCeal Malware Can Bypass Google Authentication Using Stolen Session Cookies

Sep 07, 2026Malvertising / Web Security

Cybersecurity researchers have unpacked JSCeal , a sophisticated compiled V8 JavaScript (JSC) malware with credential harvesting, surveillance, and traffic-interception capabilities. "The payloads are protected with javascript-obfuscator , using multiple techniques including RC4-protected strings, control-flow flattening, proxy functions, and operation wrappers," Check Point Research said in a technical report published last week. JSCeal was first documented by Check Point in July 2025, highlighting the threat actors' use of fake cryptocurrency trading sites to which unsuspecting users are redirected via malicious ads on Facebook and Google. The counterfeit sites instruct them to download bogus installers for TradingView that lead to the deployment of the malware. The activity overlaps with a threat cluster under the monikers WEEVILPROXY and MeadowLocust. Malvertising campaigns distributing the malware make use of two ZIP archives delivered via PowerShell: one co...

Attackers Hijack MikroTik Routers Through Internet-Exposed SSH Without Authentication

Sep 06, 2026Vulnerability / Network Security

Attackers are exploiting MikroTik routers with their Secure Shell (SSH) remote-access service, which is reachable from the internet, to gain full administrative control without authentication, according to  CERT Polska's attack warning , published on September 5. Successful attacks date to at least September 2. The Hacker News’s September 6 review of the warning found no victim count or attacker identity. MikroTik's security update  lists fixed RouterOS releases. CERT says the fixes prevent the observed attacks and recommends immediate installation, followed by a check for unauthorized configuration changes. According to the  vendor's default firewall explanation , home MikroTik devices block public access to management ports while their default firewall rules remain intact. The Hacker News checked CERT's  affected RouterOS versions  against MikroTik's listed fixes on September 6. Use the  official RouterOS downloads  for your update. ...

Four REVSTEALER-Linked Modules Disable Windows Update and Defender to Run a Crypto Miner

Sep 06, 2026Malware / Endpoint Security

Elastic Security Labs has documented four previously unreported programs associated with REVSTEALER, an emerging Windows information stealer, that remain on an infected machine after the stealer deletes itself. One of them switches off Windows Update and Microsoft Defender before running a cryptocurrency miner. The company named the four programs ProManager , WinUpdate , SoftManager , and LockAppHost and  published the findings on September 2 , along with a  technical white paper . REVSTEALER has been sold as a commercial infostealer since at least February 2026, when the earliest sample was first detected on VirusTotal. The core stealer exfiltrates browser passwords and cookies, cryptocurrency wallets, gaming accounts, messaging data, and files, then reports "complete" to its server, deletes itself, and leaves no persistence. The four newly documented programs work differently. Each installs itself into the user's profile and stays there. Elastic recovered the ...

Unpatched Magento and Adobe Commerce Zero-Day Exploited to Backdoor Online Stores

Sep 05, 2026Zero Day / Vulnerability

Attackers are exploiting a new unpatched vulnerability in Magento Open Source and Adobe Commerce that lets them run malicious code on an online store's server without logging in, Dutch e-commerce security company Sansec said in an  advisory published on September 5 . Sansec, which discovered the flaw and named it StyleSmuggler , said attacks started on September 4. "Sansec is publishing early because stores are being compromised right now," the company said. As of September 6, Adobe has not published an advisory, a CVE identifier, a patch, or a workaround, and its  Adobe Commerce security bulletin index  lists nothing after the August 11 update. A successful attack gives the attacker code execution on the store's server and installs a persistent backdoor. Sansec said all current versions are affected, including 2.4.9, and that it reproduced the full unauthenticated chain on clean Magento Open Source installations of 2.4.7, 2.4.8, and 2.4.9. Its ...

Attackers Breached JetBrains Cadence via Unpatched TeamCity, Extracting AWS Credentials

Sep 05, 2026Data Breach / Identity Security

JetBrains is urging Cadence users to revoke and rotate all credentials following a security incident last month in which unidentified threat actors exploited a recently disclosed critical vulnerability in TeamCity to breach its own environment. "Cadence users should immediately revoke or rotate all credentials and secrets that may have been used to run their Cadence executions," JetBrains said . "They should also treat all executions, including their inputs and outputs in your Cadence project, as potentially untrusted." "As the threat actors gained access to the Cadence server, any credentials or secrets stored in Cadence, contained in the compromised backup, or made available to executions on the affected server should be considered compromised and must be revoked or rotated." Cadence is a JetBrains-hosted cloud computing service that integrates with PyCharm via an optional plugin to let developers run machine learning and heavy workloads on cloud...

Critical VMware Workstation and Fusion Flaw Lets VM Admins Execute Host Code

Sep 05, 2026Vulnerability / Server Security

Broadcom has released security updates for two security flaws impacting VMware Workstation and Fusion, including one critical bug that could result in arbitrary code execution under certain conditions. The vulnerability, tracked as CVE-2026-59346 (CVSS score: 9.3), is an integer-overflow vulnerability that a local attacker with elevated privileges can exploit to run arbitrary code. "A malicious actor with local administrative privileges on a virtual machine with VMXNET3 virtual network adapter may exploit this issue to execute code on the host," Broadcom said in an alert. The tech giant credited @h4urek, @cameudis, and Stan S for discovering the issue. Also patched by Broadcom is a stack-based buffer-overflow vulnerability in HGFS ( CVE-2026-59347 , CVSS score: 8.1), which can be exploited by a bad actor with local administrative privileges on a virtual machine to execute code as the virtual machine's VMX process running on the host.

Trezor Says ShipMonk Breach Exposed 67,000 U.S. Customers' Data It Said Was Deleted

Sep 05, 2026Data Breach / Vulnerability

Hardware wallet manufacturer Trezor on Friday disclosed that another 67,000 customers from the U.S. have been impacted in a breach at its shipping provider ShipMonk. The exposed information includes customer names, email addresses, phone numbers, shipping addresses, and order numbers between November 2019 and August 2021. The breach does not affect the security of the company's hardware wallets. "Throughout our entire relationship with ShipMonk, we repeatedly requested and received written assurance confirming the deletion of the data, in line with our contract, data policy, and past communications," Trezor said . "We are very disappointed that, despite receiving this confirmation, the data was not deleted in their systems." The exposure is in addition to 13,689 customers the company disclosed last month as having had their data either fully or partially exposed. The breach, it noted at the time, was limited during its 90-day data storage policy. Trezo...

Thousands of OpenAI Agents Quietly Turned an Abandoned Wiki Into Their Coordination Channel

Sep 05, 2026Artificial Intelligence / AI Agents

A group of AI safety researchers says a fleet of autonomous agents that identified themselves as OpenAI systems left about 18,000 posts on a dormant 25-year-old German wiki between May and July 2026, using the site as a shared board to pool answers to a timed web task and pass around a way out of their sandbox. The activity was concentrated on DSEwiki , a German software developer wiki that runs on the ProWiki farm at wikiservice[.]at and had been edited about 20 times over the previous decade. The researchers, led by Sydney Von Arx of the AI safety nonprofit  Nightingale Collective , reconstructed the deleted pages from edit history and published their analysis along with a downloadable copy of the data. The wikis let anyone change a page with an ordinary web request, the kind normally used only to read a page rather than to write one. Agents that were restricted to reading the internet could therefore still write to the site, because the restriction was written a...

Attackers Exploit PaperCut Flaws to Steal Credentials From Schools and Universities

Sep 05, 2026Vulnerability / Web Security

Threat actors are exploiting the newly disclosed PaperCut flaws to facilitate credential theft in attacks targeting the education sector in the U.S. and Europe. The Arctic Wolf Adversary Research Team said it observed attackers exploiting CVE-2026-81578 and CVE-2026-82078 – an authentication bypass and remote code execution chain – to conduct command execution and reconnaissance, as well as create privileged accounts. "Observed post-exploitation activity included delivery of Windows registry hive collection tools, Metasploit/Meterpreter-related Java payloads, and commands used to identify hosts, users, processes, and sensitive configuration data," Arctic Wolf said. The cybersecurity company told The Hacker News that the activity has targeted vulnerable PaperCut servers across the education sector, impacting organizations ranging from K-12 schools to major universities in the U.S. and Europe. Some of the identified malicious activity includes - Running discover...

Phishing Campaign Sends Millions of Emails Using Invisible Unicode to Evade Filters

Sep 04, 2026Email Security / Artificial Intelligence

Microsoft is alerting of a "high-volume phishing campaign" that's using invisible Unicode tag characters to bypass email filters. "Instead of using these characters to hide instructions from people while exposing them to AI models, the attacker used them to split financial lure words such as 'funding' to prevent email filters from parsing them," the Microsoft Security Research team said . The Windows maker said the findings show AI-era evasion techniques can be adapted by threat actors in traditional phishing and spam campaigns. Attacks exploiting this approach are said to have first emerged in early February 2026. ASCII Smuggling refers to a technique where invisible or non-rendering Unicode characters are used to conceal messages or instructions inside seemingly-harmless text. As a result, human user interfaces do not render them, making the text appear completely normal to the user. However, such content can be ingested by email filters or AI...

PostgreSQL Fixes 12-Year-Old Logical Decoding Flaw Enabling Replication-Role Code Execution

Sep 04, 2026Vulnerability / Database Security

PostgreSQL has released updates to address a security flaw that allows an account with the REPLICATION attribute to run arbitrary code as the operating-system user running the database server. The flaw, tracked as CVE-2026-6471 (CVSS score: 7.2), has been present since logical decoding was introduced in PostgreSQL 9.4 in 2014. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected. Exploitation requires an account carrying the REPLICATION attribute and a server running with wal_level = logical. Backup tools, standby servers, change data capture (CDC) pipelines, and monitoring systems routinely hold that attribute. The fix, shipped on August 13, adds a server parameter called output_plugin_libraries that lists which libraries may be loaded as logical decoding output plugins, defaulting to 'pgoutput, test_decoding'. Installations using any other output plugin, wal2json, and decoderbufs among them, will have logical decoding refused aft...

New Ted Backdoor Hides Inside Victims' Own HAProxy Builds to Intercept Web Traffic

Sep 04, 2026Malware / Network Security

A previously undocumented Linux toolkit has been found compiled directly into the trojanized HAProxy load balancers of two South Korean organizations, where it intercepted web traffic and served altered pages to selected visitors. The attackers named the implant ted in debug strings left in the binary. It is not a HAProxy vulnerability, and installing it requires code execution on the host and the ability to replace the running binary. Rapid7 Labs attributed the toolkit with medium confidence to North Korean state-sponsored actors and put the two victims in South Korea's automotive and media sectors. Command-and-control (C2) requests never reach a backend server and are erased from HAProxy's own connection counters, so neither the backend logs nor the load balancer's statistics record them. "Further evidence is necessary to make a more definitive assessment," Rapid7 said. A request for one specific image path puts the filter into C2 mode, Rapid7 said i...
