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...

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 ...

SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...

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...

As many as 200,000 WordPress websites are at risk of ongoing attacks exploiting a critical unpatched security vulnerability in the Ultimate Member plugin. The flaw, tracked as CVE-2023-3460 (CVSS score: 9.8), impacts all versions of the Ultimate Member plugin, including the latest version (2.6.6) that was released on June 29, 2023. Ultimate Member is a  popular plugin  that facilitates the creation of user-profiles and communities on WordPress sites. It also provides account management features. "This is a very serious issue: unauthenticated attackers may exploit this vulnerability to create new user accounts with administrative privileges, giving them the power to take complete control of affected sites," WordPress security firm WPScan  said  in an alert. Although details about the flaw have been withheld due to active abuse, it stems from an inadequate blocklist logic that allows attackers to alter the wp_capabilities user meta value of a new user to that of ...

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...

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...

Meta's WhatsApp has rolled out updates to its proxy feature, allowing more flexibility in the kind of content that can be shared in conversations. This includes the ability to send and receive images, voice notes, files, stickers and GIFs, WhatsApp told The Hacker News. The new features were  first reported  by BBC Persian. Some of the other improvements include streamlined steps to simplify the setup process as well as the introduction of shareable links to "share functioning/valid proxy addresses to their contacts for easy and automatic installation." Support for  proxy servers  was officially launched by the messaging service  earlier this January , thereby helping users circumvent government-imposed censorship and internet shutdowns and obtain indirect access to WhatsApp. The company has also made available a  reference implementation  for setting up a proxy server with ports 80, 443, or 5222 available and a domain name that points to the serv...

An active financially motivated campaign is targeting vulnerable SSH servers to covertly ensnare them into a proxy network. "This is an active campaign in which the attacker leverages SSH for remote access, running malicious scripts that stealthily enlist victim servers into a peer-to-peer (P2P) proxy network, such as Peer2Profit or Honeygain," Akamai researcher Allen West said in a Thursday report. Unlike cryptojacking, in which a compromised system's resources are used to illicitly mine cryptocurrency, proxyjacking offers the ability for threat actors to leverage the victim's unused bandwidth to clandestinely run different services as a P2P node. This offers two-fold benefits: It not only enables the attacker to monetize the extra bandwidth with a significantly reduced resource load that would be necessary to carry out cryptojacking, it also reduces the chances of discovery. "It is a stealthier alternative to cryptojacking and has serious implications th...

MITRE has released its annual list of the Top 25 "most dangerous software weaknesses" for the year 2023. "These weaknesses lead to serious vulnerabilities in software," the U.S. Cybersecurity and Infrastructure Security Agency (CISA)  said . "An attacker can often exploit these vulnerabilities to take control of an affected system, steal data, or prevent applications from working." The  list  is based on an  analysis  of public vulnerability data in the National Vulnerability Data ( NVD ) for root cause mappings to CWE weaknesses for the previous two years. A total of 43,996 CVE entries were examined and a score was attached to each of them based on prevalence and severity.

The Iranian state-sponsored group dubbed MuddyWater has been attributed to a previously unseen command-and-control (C2) framework called  PhonyC2  that's been put to use by the actor since 2021. Evidence shows that the custom made, actively developed framework has been leveraged in the  February 2023 attack on Technion , an Israeli research institute, cybersecurity firm Deep Instinct said in a report shared with The Hacker News. What's more, additional links have been unearthed between the Python 3-based program and other attacks carried out by MuddyWater, including the  ongoing exploitation of PaperCut servers . "It is structurally and functionally similar to  MuddyC3 , a previous MuddyWater  custom C2 framework  that was written in Python 2," security researcher Simon Kenin said. "MuddyWater is continuously updating the PhonyC2 framework and changing TTPs to avoid detection." MuddyWater, also known as Mango Sandstorm (previously Mercury), is a ...
