A security shortcoming in Microsoft Azure Active Directory (AD) Open Authorization ( OAuth ) process could have been exploited to achieve full account takeover, researchers said. California-based identity and access management service Descope, which discovered and reported the issue in April 2023, dubbed it  nOAuth . "nOAuth is an authentication implementation flaw that can affect Microsoft Azure AD multi-tenant OAuth applications," Omer Cohen, chief security officer at Descope,  said . The misconfiguration has to do with how a malicious actor can modify email attributes under "Contact Information" in the Azure AD account and exploit the "Log in with Microsoft" feature to hijack a victim account. To pull off the attack, all an adversary has to do is to create and access an Azure AD admin account and modify their email address to that of a victim and take advantage of the single sign-on scheme on a vulnerable app or website. "If the app merges u...

Foreign affairs ministries in the Americas have been targeted by a Chinese state-sponsored actor named  Flea  as part of a recent campaign that spanned from late 2022 to early 2023. The cyber attacks, per Broadcom's Symantec, involved a new backdoor codenamed Graphican. Some of the other targets included a government finance department and a corporation that markets products in the Americas as well as one unspecified victim in an European country. "Flea used a large number of tools in this campaign," the company  said  in a report shared with The Hacker News, describing the threat actor as "large and well-resourced." "As well as the new Graphican backdoor, the attackers leveraged a variety of living-off-the-land tools, as well as tools that have been previously linked to Flea." Flea, also called APT15, BackdoorDiplomacy, ke3chang, Nylon Typhoon (formerly Nickel), Playful Taurus, Royal APT, and Vixen Panda, is an advanced persistent threat group tha...

A new malware called  Condi  has been observed exploiting a security vulnerability in TP-Link Archer AX21 (AX1800) Wi-Fi routers to rope the devices into a distributed denial-of-service (DDoS) botnet. Fortinet FortiGuard Labs  said  the campaign has ramped up since the end of May 2023. Condi is the work of a threat actor who goes by the online alias zxcr9999 on Telegram and runs a Telegram channel called Condi Network to advertise their warez. "The Telegram channel was started in May 2022, and the threat actor has been monetizing its botnet by providing DDoS-as-a-service and selling the malware source code," security researchers Joie Salvio and Roy Tay said. An analysis of the malware artifact reveals its ability to terminate other competing botnets on the same host. It, however, lacks a persistence mechanism, meaning the program cannot survive a system reboot. To get around this limitation, the malware deletes multiple binaries that are used to shut down or re...

VMware has flagged that a recently patched critical command injection vulnerability in Aria Operations for Networks (formerly vRealize Network Insight) has come under active exploitation in the wild. The flaw, tracked as  CVE-2023-20887 , could  allow  a malicious actor with network access to the product to perform a command injection attack, resulting in remote code execution. It impacts VMware Aria Operations Networks versions 6.x, with fixes released in versions 6.2, 6.3, 6.4, 6.5.1, 6.6, 6.7, 6.8, 6.9, and 6.10 on June 7, 2023. Now according to an update shared by the virtualization services provider on June 20, 2023, the flaw has been weaponized in real-world attacks, although the exact specifics are unknown as yet. "VMware has confirmed that exploitation of CVE-2023-20887 has occurred in the wild," the company  noted . Data gathered by threat intelligence firm GreyNoise  shows  active exploitation of the flaw from two different IP addresses loc...

Three security vulnerabilities have been disclosed in operational technology (OT) products from Wago and Schneider Electric. The flaws, per Forescout, are part of a  broader   set  of  shortcomings  collectively called  OT:ICEFALL , which now comprises a total of 61 issues spanning 13 different vendors. "OT:ICEFALL demonstrates the need for tighter scrutiny of, and improvements to, processes related to secure design, patching and testing in OT device vendors," the company  said  in a report shared with The Hacker News. The most severe of the flaws is  CVE-2022-46680  (CVSS score: 8.8), which concerns the plaintext transmission of credentials in the ION/TCP protocol used by power meters from Schneider Electric. Successful exploitation of the bug could enable threat actors to gain control of vulnerable devices. It's worth noting that CVE-2022-46680 is one among the 56 flaws  originally unearthed  by Forescout in June 2022. ...

Zyxel has rolled out security updates to address a critical security flaw in its network-attached storage (NAS) devices that could result in the execution of arbitrary commands on affected systems. Tracked as  CVE-2023-27992  (CVSS score: 9.8), the issue has been described as a pre-authentication command injection vulnerability. "The pre-authentication command injection vulnerability in some Zyxel NAS devices could allow an unauthenticated attacker to execute some operating system (OS) commands remotely by sending a crafted HTTP request," Zyxel  said  in an advisory published today. Andrej Zaujec, NCSC-FI, and Maxim Suslov have been credited with discovering and reporting the flaw. The following versions are impacted by CVE-2023-27992 - NAS326 (V5.21(AAZF.13)C0 and earlier, patched in V5.21(AAZF.14)C0), NAS540 (V5.21(AATB.10)C0 and earlier, patched in V5.21(AATB.11)C0), and NAS542 (V5.21(ABAG.10)C0 and earlier, patched in V5.21(ABAG.11)C0) The alert comes ...
