Alert: 330,000 FortiGate Firewalls Still Unpatched to CVE-2023-27997 RCE Flaw

Jul 04, 2023 Network Security / Exploit
No less than 330,000 FortiGate firewalls are still unpatched and vulnerable to CVE-2023-27997, a critical security flaw affecting Fortinet devices that has come under active exploitation in the wild. Cybersecurity firm Bishop Fox, in a  report  published last week, said that out of nearly 490,000 Fortinet SSL-VPN interfaces exposed on the internet, about 69 percent remain unpatched. CVE-2023-27997  (CVSS score: 9.8), also called XORtigate, is a critical vulnerability impacting Fortinet FortiOS and FortiProxy SSL-VPN appliances that could allow a remote attacker to execute arbitrary code or commands via specifically crafted requests. Patches were released by Fortinet last month in versions 6.0.17, 6.2.15, 6.4.13, 7.0.12, and 7.2.5, although the company  acknowledged  that the flaw may have been "exploited in a limited number of cases" in attacks targeting government, manufacturing, and critical infrastructure sectors. Bishop Fox's analysis further found th...
Chinese Hackers Use HTML Smuggling to Infiltrate European Ministries with PlugX

Chinese Hackers Use HTML Smuggling to Infiltrate European Ministries with PlugX

Jul 03, 2023 Malware Attack / Cyberespionage
A Chinese nation-state group has been observed targeting Foreign Affairs ministries and embassies in Europe using  HTML smuggling techniques  to deliver the PlugX remote access trojan on compromised systems. Cybersecurity firm Check Point said the activity, dubbed  SmugX , has been ongoing since at least December 2022, adding it's part of a broader trend of Chinese adversaries shifting their focus to Europe. "The campaign uses new delivery methods to deploy (most notably – HTML Smuggling) a new variant of PlugX, an implant commonly associated with a wide variety of Chinese threat actors," Check Point  said . "Although the payload itself remains similar to the one found in older PlugX variants, its delivery methods result in low detection rates, which until recently helped the campaign fly under the radar." The exact identity of the threat actor behind the operation is a little hazy, although existing clues point in the direction of  Mustang Panda , which a...

Between Buzz and Reality: The CTEM Conversation We All Need

Between Buzz and Reality: The CTEM Conversation We All Need

Jun 24, 2025Threat Exposure Management
I had the honor of hosting the first episode of the Xposure Podcast live from Xposure Summit 2025. And I couldn't have asked for a better kickoff panel: three cybersecurity leaders who don't just talk security, they live it. Let me introduce them. Alex Delay , CISO at IDB Bank, knows what it means to defend a highly regulated environment. Ben Mead , Director of Cybersecurity at Avidity Biosciences, brings a forward-thinking security perspective that reflects the innovation behind Avidity's targeted RNA therapeutics. Last but not least, Michael Francess , Director of Cybersecurity Advanced Threat at Wyndham Hotels and Resorts, leads the charge in protecting the franchise. Each brought a unique vantage point to a common challenge: applying Continuous Threat Exposure Management (CTEM) to complex production environments. Gartner made waves in 2023 with a bold prediction: organizations that prioritize CTEM will be three times less likely to be breached by 2026. But here's the kicker -...
Evasive Meduza Stealer Targets 19 Password Managers and 76 Crypto Wallets

Evasive Meduza Stealer Targets 19 Password Managers and 76 Crypto Wallets

Jul 03, 2023 Malware / Hacking
In yet another sign of a lucrative crimeware-as-a-service ( CaaS ) ecosystem, cybersecurity researchers have discovered a new Windows-based information stealer called  Meduza Stealer  that's actively being developed by its author to evade detection by software solutions. "The Meduza Stealer has a singular objective: comprehensive data theft," Uptycs  said  in a new report. "It pilfers users' browsing activities, extracting a wide array of browser-related data." "From critical login credentials to the valuable record of browsing history and meticulously curated bookmarks, no digital artifact is safe. Even crypto wallet extensions, password managers, and 2FA extensions are vulnerable." Despite the similarity in features, Meduza boasts of a "crafty" operational design that eschews the use of obfuscation techniques and promptly terminates its execution on compromised hosts should a connection to the attacker's server fail. It's ...
BlackCat Operators Distributing Ransomware Disguised as WinSCP via Malvertising

BlackCat Operators Distributing Ransomware Disguised as WinSCP via Malvertising

Jul 03, 2023 Malvertising / Endpoint Security
Threat actors associated with the  BlackCat ransomware  have been observed employing malvertising tricks to distribute rogue installers of the WinSCP file transfer application. "Malicious actors used malvertising to distribute a piece of malware via cloned webpages of legitimate organizations," Trend Micro researchers  said  in an analysis published last week. "In this case, the distribution involved a webpage of the well-known application WinSCP, an open-source Windows application for file transfer." Malvertising   refers  to the use of  SEO poisoning techniques  to spread malware via online advertising. It typically involves hijacking a chosen set of keywords (e.g., "WinSCP Download") to display bogus ads on Bing and Google search results pages with the goal of redirecting unsuspecting users to sketchy pages. The idea is to trick users searching for applications like WinSCP into downloading malware, in this instance, a backdoor that contains...

Beware: New 'RustBucket' Malware Variant Targeting macOS Users

Beware: New 'RustBucket' Malware Variant Targeting macOS Users

Jul 01, 2023 Endpoint Security / Malware
Researchers have pulled back the curtain on an updated version of an Apple macOS malware called RustBucket that comes with improved capabilities to establish persistence and avoid detection by security software. "This variant of RustBucket, a malware family that targets macOS systems, adds persistence capabilities not previously observed," Elastic Security Labs researchers  said  in a report published this week, adding it's "leveraging a dynamic network infrastructure methodology for command-and-control." RustBucket is the work of a North Korean threat actor known as BlueNoroff, which is part of a larger intrusion set tracked under the name  Lazarus Group , an elite hacking unit supervised by the Reconnaissance General Bureau (RGB), the country's primary intelligence agency. The malware came to light in April 2023, when Jamf Threat Labs  described  it as an AppleScript-based backdoor capable of retrieving a second-stage payload from a remote server. Ela...
Iranian Hackers Using POWERSTAR Backdoor in Targeted Espionage Attacks

Iranian Hackers Using POWERSTAR Backdoor in Targeted Espionage Attacks

Jun 30, 2023 Cyber Espionage/ Malware
Charming Kitten, the nation-state actor affiliated with Iran's Islamic Revolutionary Guard Corps (IRGC), has been attributed to a bespoke spear-phishing campaign that delivers an updated version of a fully-featured PowerShell backdoor called POWERSTAR . "There have been improved operational security measures placed in the malware to make it more difficult to analyze and collect intelligence," Volexity researchers Ankur Saini and Charlie Gardner said in a report published this week. The threat actor is something of an expert when it comes to employing social engineering to lure targets, often crafting tailored fake personas on social media platforms and engaging in sustained conversations to build rapport before sending a malicious link. It's also tracked under the names APT35, Cobalt Illusion, Mint Sandstorm (formerly Phosphorus), and Yellow Garuda. Recent intrusions orchestrated by Charming Kitten have made use of other implants such as PowerLess and BellaCiao...
