Researchers Identify Multiple China Hacker Groups Exploiting Ivanti Security Flaws

Apr 05, 2024 Advanced Persistent Threat
Multiple China-nexus threat actors have been linked to the zero-day exploitation of three security flaws impacting Ivanti appliances (CVE-2023-46805, CVE-2024-21887, and CVE-2024-21893). The clusters are being tracked by Mandiant under the uncategorized monikers  UNC5221 , UNC5266, UNC5291,  UNC5325 , UNC5330, and UNC5337. Also previously linked to the exploitation spree is a Chinese hacking crew called UNC3886 , whose tradecraft is notable for weaponizing zero-day bugs in Fortinet and VMware to breach target networks. The Google Cloud subsidiary said it has also observed financially motivated actors exploiting CVE-2023-46805 and CVE-2024-21887, likely in an attempt to conduct cryptocurrency mining operations. "UNC5266 overlaps in part with UNC3569, a China-nexus espionage actor that has been observed exploiting vulnerabilities in Aspera Faspex, Microsoft Exchange, and Oracle Web Applications Desktop Integrator, among others, to gain initial access to target environments,"

The Secret Weakness Execs Are Overlooking: Non-Human Identities

The Secret Weakness Execs Are Overlooking: Non-Human Identities

Oct 03, 2024Enterprise Security / Cloud Security
For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

U.S. Feds Shut Down China-Linked "KV-Botnet" Targeting SOHO Routers

Feb 01, 2024 Cyber Threat / Network Security
The U.S. government on Wednesday said it took steps to neutralize a botnet comprising hundreds of U.S.-based small office and home office (SOHO) routers hijacked by a China-linked state-sponsored threat actor called Volt Typhoon and blunt the impact posed by the hacking campaign. The existence of the botnet, dubbed  KV-botnet , was  first disclosed  by the Black Lotus Labs team at Lumen Technologies in mid-December 2023. The law enforcement effort was  reported  by Reuters earlier this week. "The vast majority of routers that comprised the KV-botnet were Cisco and NetGear routers that were vulnerable because they had reached 'end of life' status; that is, they were no longer supported through their manufacturer's security patches or other software updates," the Department of Justice (DoJ)  said  in a press statement. Volt Typhoon  (aka DEV-0391, Bronze Silhouette, Insidious Taurus, or Vanguard Panda) is the moniker assigned to a China-based adversarial collect

Chinese Hackers Silently Weaponized VMware Zero-Day Flaw for 2 Years

Jan 20, 2024 Zero Day / Cyber Espionage
An advanced China-nexus cyber espionage group previously linked to the exploitation of security flaws in VMware and Fortinet appliances has been attributed to the abuse of a critical vulnerability in VMware vCenter Server as a zero-day since late 2021. "UNC3886 has a track record of utilizing zero-day vulnerabilities to complete their mission without being detected, and this latest example further demonstrates their capabilities," Google-owned Mandiant said in a Friday report. The vulnerability in question is CVE-2023-34048 (CVSS score: 9.8), an out-of-bounds write that could be put to use by a malicious actor with network access to vCenter Server to achieve remote code execution. It was fixed by the Broadcom-owned company on October 24, 2023. The virtualization services provider, earlier this week, updated its advisory to acknowledge that "exploitation of CVE-2023-34048 has occurred in the wild." UNC3886 first came to light in September 2022 when it was

PEACHPIT: Massive Ad Fraud Botnet Powered by Millions of Hacked Android and iOS

Oct 09, 2023 Botnet / Cyber Threat
An ad fraud botnet dubbed  PEACHPIT  leveraged an army of hundreds of thousands of Android and iOS devices to generate illicit profits for the threat actors behind the scheme. The botnet is part of a larger China-based operation codenamed  BADBOX , which also entails selling off-brand mobile and connected TV (CTV) devices on popular online retailers and resale sites that are backdoored with an  Android malware strain  called  Triada . "The PEACHPIT botnet's conglomerate of associated apps were found in 227 countries and territories, with an estimated peak of 121,000 devices a day on Android and 159,000 devices a day on iOS," HUMAN  said . The infections are said to have been realized through a collection of 39 apps that were installed more than 15 million times. Devices fitted with the BADBOX malware allowed the operators to steal sensitive data, create residential proxy exit peers, and commit ad fraud through the bogus apps. It's currently not clear how the And

China Accuses U.S. of Decade-Long Cyber Espionage Campaign Against Huawei Servers

Sep 21, 2023 Cyber Espionage / Spyware
China's Ministry of State Security (MSS) has accused the U.S. of breaking into Huawei's servers, stealing critical data, and implanting backdoors since 2009, amid mounting geopolitical tensions between the two countries. In a  message  posted on WeChat, the government authority said U.S. intelligence agencies have "done everything possible" to conduct surveillance, secret theft, and intrusions on many countries around the world, including China, using a "powerful cyber attack arsenal." Specifics about the alleged hacks were not shared. It explicitly singled out the U.S. National Security Agency's (NSA) Computer Network Operations (formerly the Office of Tailored Access Operations or TAO) as having "repeatedly carried out systematic and platform-based attacks" against the country to plunder its "important data resources." The post went on to claim that the cyber-warfare intelligence-gathering unit hacked Huawei's servers in 200
Outlook Hack: Microsoft Reveals How a Crash Dump Led to a Major Security Breach

Outlook Hack: Microsoft Reveals How a Crash Dump Led to a Major Security Breach

Sep 07, 2023 Cyber Attack / Email Hacking
Microsoft on Wednesday revealed that a China-based threat actor known as  Storm-0558  acquired the inactive consumer signing key to forge tokens and access Outlook by compromising an engineer's corporate account. This enabled the adversary to access a debugging environment that contained information pertaining to a crash of the consumer signing system and steal the key. The system crash took place in April 2021. "A consumer signing system crash in April of 2021 resulted in a snapshot of the crashed process ('crash dump')," the Microsoft Security Response Center (MSRC)  said  in a post-mortem report. "The crash dumps, which redact sensitive information, should not include the signing key. In this case, a race condition allowed the key to be present in the crash dump. The key material's presence in the crash dump was not detected by our systems." The Windows maker said the crash dump was moved to a debugging environment on the internet-connected corporate network, from where Storm-

China-Linked Flax Typhoon Cyber Espionage Targets Taiwan's Key Sectors

Aug 25, 2023 Cyber Espionage
A nation-state activity group originating from China has been linked to cyber attacks on dozens of organizations in Taiwan as part of a suspected espionage campaign. The Microsoft Threat Intelligence team is tracking the activity under the name  Flax Typhoon , which is also known as Ethereal Panda. "Flax Typhoon gains and maintains long-term access to Taiwanese organizations' networks with minimal use of malware, relying on tools built into the operating system, along with some normally benign software to quietly remain in these networks," the company  said . It further said it hasn't observed the group weaponize the access to conduct data-collection and exfiltration. A majority of the targets include government agencies, educational institutions, critical manufacturing, and information technology organizations in Taiwan. A smaller number of victims have also been detected in Southeast Asia, North America, and Africa. The group is suspected to have been active si

Researchers Shed Light on APT31's Advanced Backdoors and Data Exfiltration Tactics

Aug 11, 2023 Malware / Cyber Attack
The Chinese threat actor known as APT31 (aka Bronze Vinewood, Judgement Panda, or Violet Typhoon) has been linked to a set of advanced backdoors that are capable of exfiltrating harvested sensitive information to Dropbox. The malware is part of a broader collection of  more than 15 implants  that have been put to use by the adversary in attacks targeting industrial organizations in Eastern Europe in 2022. "The attackers aimed to establish a permanent channel for data exfiltration, including data stored on air-gapped systems," Kaspersky  said  in an analysis spotlighting APT31's previously undocumented tradecraft. The intrusions employ a three-stage malware stack, each focused on disparate aspects of the attack chain: setting up persistence, gathering sensitive data, and transmitting the information to a remote server under the threat actor's control. Some variants of the second-stage backdoors also come with features designed to look up file names in the Microso
