The recent attack against  Microsoft's email infrastructure  by a Chinese nation-state actor referred to as Storm-0558 is said to have a broader scope than previously thought. According to cloud security company Wiz, the inactive Microsoft account (MSA) consumer signing key used to forge Azure Active Directory (Azure AD or AAD) tokens to gain illicit access to Outlook Web Access (OWA) and Outlook.com could also have allowed the adversary to forge access tokens for various types of Azure AD applications. This  includes  every application that supports personal account authentication, such as OneDrive, SharePoint, and Teams; customers applications that support the "Login with Microsoft functionality," and multi-tenant applications in certain conditions. "Everything in the world of Microsoft leverages Azure Active Directory auth tokens for access," Ami Luttwak, chief technology officer and co-founder of Wiz, said in a statement. "An attacker with an AAD si...

The prolific China-linked nation-state actor known as APT41 has been linked to two previously undocumented strains of Android spyware called WyrmSpy and DragonEgg. "Known for its exploitation of web-facing applications and infiltration of traditional endpoint devices, an established threat actor like APT 41 including mobile in its arsenal of malware shows how mobile endpoints are high-value targets with coveted corporate and personal data," Lookout  said  in a report shared with The Hacker News. APT41, also tracked under the names Axiom, Blackfly, Brass Typhoon (formerly Barium), Bronze Atlas, HOODOO, Wicked Panda, and Winnti, is known to be operational since at least 2007, targeting a wide range of industries to conduct intellectual property theft. Recent attacks mounted by the adversarial collective have  leveraged  an open-source red teaming tool known as Google Command and Control (GC2) as part of attacks aimed at media and job platforms in Taiwan and Italy. ...

An unnamed Federal Civilian Executive Branch (FCEB) agency in the U.S. detected anomalous email activity in mid-June 2023, leading to Microsoft's discovery of a new China-linked  espionage campaign  targeting two dozen organizations. The details come from a joint cybersecurity advisory released by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and Federal Bureau of Investigation (FBI) on July 12, 2023. "In June 2023, a Federal Civilian Executive Branch (FCEB) agency identified suspicious activity in their Microsoft 365 (M365) cloud environment," the authorities  said . "Microsoft determined that advanced persistent threat (APT) actors accessed and exfiltrated unclassified Exchange Online Outlook data." While the name of the government agency was not revealed,  CNN  and  the Washington Post  reported it was the U.S. State Department, citing people familiar with the matter. Also targeted were the Commerce Department as well as the e...

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...

Microsoft on Tuesday  revealed  that it repelled a cyber attack staged by a Chinese nation-state actor targeting two dozen organizations, some of which include government agencies, in a cyber espionage campaign designed to acquire confidential data. The attacks, which commenced on May 15, 2023, entailed access to email accounts affecting approximately 25 entities and a small number of related individual consumer accounts. The tech giant attributed the campaign to Storm-0558, describing it as a nation-state activity group based out of China that primarily singles out government agencies in Western Europe. "They focus on espionage, data theft, and credential access," Microsoft  said . "They are also known to use custom malware that Microsoft tracks as Cigril and Bling, for credential access." The breach is said to have been detected a month later on June 16, 2023, after an unidentified customer reported the anomalous email activity to the company. Microsoft sai...

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...

The Chinese cyber espionage actor known as  Camaro Dragon  has been observed leveraging a new strain of self-propagating malware that spreads through compromised USB drives. "While their primary focus has traditionally been Southeast Asian countries, this latest discovery reveals their global reach and highlights the alarming role USB drives play in spreading malware," Check Point said in new research shared with The Hacker News. The cybersecurity company, which found evidence of USB malware infections in Myanmar, South Korea, Great Britain, India, and Russia, said the findings are the result of a cyber incident that it investigated at an unnamed European hospital in early 2023. The probe found that the entity was not directly targeted by the adversary but rather suffered a breach via an employee's USB drive, which became infected when it was plugged into a colleague's computer at a conference in Asia. "Consequently, upon returning to the healthcare institu...

A Chinese-speaking phishing gang dubbed  PostalFurious  has been linked to a new SMS campaign that's targeting users in the U.A.E. by masquerading as postal services and toll operators, per Group-IB. The fraudulent scheme entails sending users bogus text messages asking them to pay a vehicle trip fee to avoid additional fines. The messages also contain a shortened URL to conceal the actual phishing link. Clicking on the link directs the unsuspecting recipients to a fake landing page that's designed to capture payment credentials and personal data. The campaign is estimated to be active as of April 15, 2023. "The URLs from the texts lead to fake branded payment pages that ask for personal details, such as name, address, and credit card information," Group-IB  said . "The phishing pages appropriate the official name and logo of the impersonated postal service provider." The exact scale of the attacks is currently unknown. What's known is that the tex...

The Chinese nation-state group known as  Camaro Dragon  has been linked to yet another backdoor that's designed to meet its intelligence-gathering goals. Israeli cybersecurity firm Check Point, which  dubbed  the Go-based malware TinyNote, said it functions as a first-stage payload capable of "basic machine enumeration and command execution via PowerShell or Goroutines." What the malware lacks in terms of sophistication, it makes up for it when it comes to establishing redundant methods to retain access to the compromised host by means of multiple persistency tasks and varied methods to communicate with different servers. Camaro Dragon overlaps with a threat actor widely tracked as Mustang Panda, a state-sponsored group from China that is known to be active since at least 2012. The adversarial collective was recently in the spotlight for a custom bespoke firmware implant called  Horse Shell  that co-opts TP-Link routers into a mesh network capable of ...

A stealthy China-based group managed to establish a persistent foothold into critical infrastructure organizations in the U.S. and Guam without being detected,  Microsoft  and  the "Five Eyes" nations  said on Wednesday. The tech giant's threat intelligence team is tracking the activity, which includes post-compromise credential access and network system discovery, under the name  Volt Typhoon . The state-sponsored actor is  geared  towards espionage and information gathering, with the cluster active since June 2021 and obscuring its intrusion footprint by taking advantage of tools already installed or built into infected machines. Some of the prominent sectors targeted include communications, manufacturing, utility, transportation, construction, maritime, government, information technology, and education. The company further assessed with moderate confidence that the campaign is "pursuing development of capabilities that could disrupt critical c...

The  rising   geopolitical tensions  between China and Taiwan in recent months have sparked a noticeable uptick in cyber attacks on the East Asian island country. "From malicious emails and URLs to malware, the strain between China's claim of Taiwan as part of its territory and Taiwan's maintained independence has evolved into a worrying surge in attacks," the Trellix Advanced Research Center  said  in a new report. The attacks, which have targeted a variety of sectors in the region, are mainly designed to deliver malware and steal sensitive information, the cybersecurity firm said, adding it detected a four-fold jump in the volume of malicious emails between April 7 and April 10, 2023. Some of the most impacted industry verticals during the four-day time period were networking, manufacturing, and logistics. What's more, the spike in malicious emails targeting Taiwan was followed by a 15x increase in PlugX detections between April 10 and April 12, 2023, in...

A Chinese state-sponsored hacking outfit has resurfaced with a new campaign targeting government, healthcare, technology, and manufacturing entities based in Taiwan, Thailand, the Philippines, and Fiji after more than six months of no activity. Trend Micro  attributed  the intrusion set to a cyber espionage group it tracks under the name  Earth Longzhi , which is a subgroup within  APT41  (aka HOODOO or Winnti) and shares overlaps with various other clusters known as Earth Baku, SparklingGoblin, and GroupCC. Earth Longzhi was  first documented  by the cybersecurity firm in November 2022, detailing its attacks against various organizations located in East and Southeast Asia as well as Ukraine. Attack chains mounted by the threat actor leverage vulnerable public-facing applications as entry points to deploy the  BEHINDER web shell , and then leverage that access to drop additional payloads, including a new variant of a Cobalt Strike loader calle...

The Chinese nation-state group dubbed  Alloy Taurus  is using a Linux variant of a backdoor called PingPull as well as a new undocumented tool codenamed Sword2033. That's according to findings from Palo Alto Networks Unit 42, which  discovered  recent malicious cyber activity carried out by the group targeting South Africa and Nepal. Alloy Taurus is the constellation-themed moniker assigned to a threat actor that's known for its attacks targeting telecom companies since at least 2012. It's also tracked by Microsoft as Granite Typhoon (previously Gallium). Last month, the adversary was attributed to a campaign called  Tainted Love  targeting telecommunication providers in the Middle East as part of a broader operation referred to as Soft Cell. Recent cyber espionage attacks mounted by Alloy Taurus have also broadened their victimology footprint to include financial institutions and government entities. PingPull,  first documented  by Unit 42...

The advanced persistent threat (APT) group referred to as  Evasive Panda  has been observed targeting an international non-governmental organization (NGO) in Mainland China with malware delivered via update channels of legitimate applications like Tencent QQ. The attack chains are designed to distribute a Windows installer for MgBot malware, ESET security researcher Facundo Muñoz said in a new report published today. The activity commenced in November 2020 and continued throughout 2021. Evasive Panda, also known as Bronze Highland and Daggerfly, is a Chinese-speaking APT group that has been attributed to a series of  cyber espionage attacks  targeting various entities in China, Hong Kong, and other countries located in East and South Asia since at least late December 2012. The group's hallmark is the use of the custom MgBot modular malware framework, which is capable of receiving additional components on the fly to expand on its intelligence-gathering capabiliti...

A Chinese nation-state group targeted an unnamed Taiwanese media organization to deliver an open source red teaming tool known as Google Command and Control ( GC2 ) amid broader abuse of Google's infrastructure for malicious ends. The tech giant's Threat Analysis Group (TAG) attributed the campaign to a threat actor it tracks under the  geological  and  geographical-themed  moniker  HOODOO , which is also known by the names  APT41 , Barium, Bronze Atlas, Wicked Panda, and  Winnti . The starting point of the attack is a phishing email that contains links to a password-protected file hosted on Google Drive, which, in turn, incorporates the Go-based GC2 tool to read commands from Google Sheets and exfiltrate data using the cloud storage service. "After installation on the victim machine, the malware queries Google Sheets to obtain attacker commands," Google's cloud division  said  in its sixth Threat Horizons Report. "In addition to exfiltr...

A Chinese state-sponsored threat activity group tracked as  RedGolf  has been  attributed  to the use of a custom Windows and Linux backdoor called KEYPLUG. "RedGolf is a particularly prolific Chinese state-sponsored threat actor group that has likely been active for many years against a wide range of industries globally," Recorded Future told The Hacker News. "The group has shown the ability to rapidly weaponize  newly reported vulnerabilities (e.g. Log4Shell and  ProxyLogon ) and has a history of developing and using a large range of custom malware families." The use of KEYPLUG by Chinese threat actors was  first disclosed  by Google-owned Mandiant in March 2022 in attacks targeting multiple U.S. state government networks between May 2021 and February 2022. Then in October 2022, Malwarebytes  detailed  a separate set of attacks targeting government entities in Sri Lanka in early August that leveraged a novel implant dubbed DBox...

An unknown Chinese state-sponsored hacking group has been linked to a novel piece of malware aimed at Linux servers. French cybersecurity firm ExaTrack, which found three samples of the previously documented malicious software that date back to early 2022, dubbed it  Mélofée . The newest of the three artifacts is designed to drop a kernel-mode rootkit that's based on an open source project referred to as  Reptile . "According to the vermagic metadata, it is compiled for a kernel version 5.10.112-108.499.amzn2.x86_64," the company  said  in a report. "The rootkit has a limited set of features, mainly installing a hook designed for hiding itself." Both the implant and the rootkit are said to be deployed using shell commands that download an installer and a custom binary package from a remote server. The installer takes the binary package as an argument and then extracts the rootkit as well as a server implant module that's currently under active develop...

A recent campaign undertaken by  Earth Preta  indicates that nation-state groups aligned with China are getting increasingly proficient at bypassing security solutions. The  threat actor , active since at least 2012, is tracked by the broader cybersecurity community under Bronze President, HoneyMyte, Mustang Panda, RedDelta, and Red Lich. Attack chains mounted by the group commence with a spear-phishing email to deploy a wide range of tools for backdoor access, command-and-control (C2), and data exfiltration. These messages come bearing with malicious lure archives distributed via Dropbox or Google Drive links that employ DLL side-loading, LNK shortcut files, and fake file extensions as arrival vectors to obtain a foothold and drop backdoors like  TONEINS, TONESHELL, PUBLOAD , and  MQsTTang  (aka QMAGENT). Similar infection chains utilizing Google Drive links have been observed  delivering Cobalt Strike  as early as April 2021. "Earth Preta...
