A governmental entity in Guyana has been targeted as part of a cyber espionage campaign dubbed  Operation Jacana . The  activity , which was detected by ESET in February 2023, entailed a spear-phishing attack that led to the deployment of a hitherto undocumented implant written in C++ called DinodasRAT. The Slovak cybersecurity firm said it could link the intrusion to a known threat actor or group, but attributed with medium confidence to a China-nexus adversary owing to the use of  PlugX  (aka Korplug), a remote access trojan common to Chinese hacking crews. "This campaign was targeted, as the threat actors crafted their emails specifically to entice their chosen victim organization," ESET  said  in a report shared with The Hacker News. "After successfully compromising an initial but limited set of machines with DinodasRAT, the operators proceeded to move inside and breach the target's internal network, where they again deployed this backdoor." The ...

A new Android banking trojan named GoldDigger has been found targeting several financial applications with an aim to siphon victims' funds and backdoor infected devices. "The malware targets more than 50 Vietnamese banking, e-wallet and crypto wallet applications," Group-IB  said . "There are indications that this threat might be poised to extend its reach across the wider APAC region and to Spanish-speaking countries." The malware was  first detected  by the Singapore-headquartered company in August 2023, although there is evidence to suggest that it has been active since June 2023. While the exact scale of the infections is currently not known, the malicious apps have been found to impersonate a Vietnamese government portal and an energy company to request intrusive permissions to meet its data-gathering goals. This primarily includes  abusing   Android's accessibility services , which is intended to assist users with disabilities to use the apps, in...

Apple on Wednesday rolled out security patches to address a new zero-day flaw in iOS and iPadOS that it said has come under active exploitation in the wild. Tracked as  CVE-2023-42824 , the kernel vulnerability could be abused by a local attacker to elevate their privileges. The iPhone maker said it addressed the problem with improved checks. "Apple is aware of a report that this issue may have been actively exploited against versions of iOS before iOS 16.6," the company  noted  in a terse advisory. While additional details about the nature of the attacks and the identity of the threat actors perpetrating them are currently unknown, successful exploitation likely hinges on an attacker already obtaining an initial foothold by some other means. Apple's latest update also resolves  CVE-2023-5217  impacting the WebRTC component, which Google last week described as a heap-based buffer overflow in the VP8 compression format in libvpx. The patches, iOS 17.0.3 an...

New findings have identified connections between an Android spyware called DragonEgg and another sophisticated modular iOS surveillanceware tool named LightSpy . DragonEgg , alongside WyrmSpy (aka AndroidControl), was  first disclosed  by Lookout in July 2023 as a strain of malware capable of gathering sensitive data from Android devices. It was attributed to the Chinese nation-state group APT41. On the other hand, details about LightSpy came to light in March 2020 as part of a campaign dubbed  Operation Poisoned News  in which Apple iPhone users in Hong Kong were targeted with watering hole attacks to install the spyware. Now, according to Dutch mobile security firm ThreatFabric, DragonEgg attack chains involve the use of a trojanized Telegram app that's designed to download a second-stage payload (smallmload.jar), which, in turn, is configured to download a third component codenamed Core. Further analysis of the artifacts has revealed that the Android varian...

Today, mid-sized companies and their CISOs are struggling to handle the growing threat of SaaS security with limited manpower and tight budgets. Now, this may be changing. By focusing on the critical SaaS security needs of these companies, a new approach has emerged that can be  launched for $1,500 a year .

Wing also provides the ability to generate compliance-ready access reports that customers can then send to thei...

A new deceptive package hidden within the npm package registry has been uncovered deploying an open-source rootkit called r77 , marking the first time a rogue package has delivered rootkit functionality. The package in question is  node-hide-console-windows , which mimics the legitimate npm package  node-hide-console-window  in what's an instance of a typosquatting campaign. It was  downloaded 704 times  over the past two months before it was taken down. ReversingLabs, which  first detected  the activity in August 2023, said the package "downloaded a Discord bot that facilitated the planting of an open-source rootkit, r77," adding it "suggests that open-source projects may increasingly be seen as an avenue by which to distribute malware." The malicious code, per the software supply chain security firm, is contained within the package's index.js file that, upon execution, fetches an executable that's automatically run. The executable in question ...

Microsoft has detailed a new campaign in which attackers unsuccessfully attempted to move laterally to a cloud environment through an SQL Server instance. "The attackers initially exploited a SQL injection vulnerability in an application within the target's environment," security researchers Sunders Bruskin, Hagai Ran Kestenberg, and Fady Nasereldeen  said  in a Tuesday report. "This allowed the attacker to gain access and elevated permissions on a Microsoft SQL Server instance deployed in Azure Virtual Machine (VM)." In the next stage, the threat actors leveraged the new permissions to attempt to move laterally to additional cloud resources by abusing the server's cloud identity, which may possess elevated permissions to likely carry out various malicious actions in the cloud that the identity has access to. Microsoft said it did not find any evidence to suggest that the attackers successfully moved laterally to the cloud resources using the technique...

A new Linux security vulnerability dubbed Looney Tunables has been discovered in the GNU C library's ld.so dynamic loader that, if successfully exploited, could lead to a local privilege escalation and allow a threat actor to gain root privileges. Tracked as  CVE-2023-4911  (CVSS score: 7.8), the issue is a buffer overflow that resides in the dynamic loader's processing of the  GLIBC_TUNABLES environment variable . Cybersecurity firm Qualys, which  disclosed  details of the bug, said it was introduced as part of a code commit made in April 2021. The GNU C library, also called  glibc , is a core library in Linux-based systems that offers foundational features such as open, read, write, malloc, printf, getaddrinfo, dlopen, pthread_create, crypt, login, and exit. glibc's  dynamic loader  is a crucial component that's responsible for preparing and running programs, including finding the necessarily shared object dependencies required as well as l...

Chipmaker Qualcomm has released security updates to address 17 vulnerabilities in various components, while warning that three other zero-days have come under active exploitation. Of the 17 flaws, three are rated Critical, 13 are rated High, and one is rated Medium in severity.
