Active flaws in the PowerShell Gallery could be weaponized by threat actors to pull off supply chain attacks against the registry's users. "These flaws make typosquatting attacks inevitable in this registry, while also making it extremely difficult for users to identify the true owner of a package," Aqua security researchers Mor Weinberger, Yakir Kadkoda, and Ilay Goldman said in a report shared with The Hacker News. Maintained by Microsoft,  PowerShell Gallery  is a  central repository  for sharing and acquiring PowerShell code, including PowerShell modules, scripts, and Desired State Configuration (DSC) resources. The registry boasts of 11,829 unique packages and 244,615 packages in total. The issues identified by the cloud security firm have to do with the service's lax policy surrounding package names, lacking protections against typosquatting attacks, as a result enabling attackers to upload malicious PowerShell modules that appear genuine to unsuspecting u...

More and more organizations are choosing Google Workspace as their default employee toolset of choice. But despite the productivity advantages, this organizational action also incurs a new security debt. Security teams now have to find a way to adjust their security architecture to this new cloud workload. Some teams may rely on their existing network security solutions. According to a  new guide , this is a hit and a miss. Network solutions, the guide claims, just don't cover all SaaS and browsing requirements. Meanwhile, Google offers a wide range of native security functionalities built-in to Chrome. These functionalities enable the organization to leverage the browser for consolidating security, simplifying operations and reducing costs. If you're wary about trusting Chrome with your security, then the guide is recommended to read. In great detail, it explains which security features Chrome offers users. These include: Forcing users to sign into Chrome, to ensure the ...

Google on Tuesday announced the first quantum resilient FIDO2 security key implementation as part of its OpenSK security keys initiative. "This open-source hardware optimized implementation uses a novel ECC/Dilithium hybrid signature schema that benefits from the security of ECC against standard attacks and Dilithium's resilience against quantum attacks," Elie Bursztein and Fabian Kaczmarczyck  said . OpenSK  is an open-source implementation for security keys written in Rust that supports both FIDO U2F and FIDO2 standards. The development comes less than a week after the tech giant  said  it plans to add support for quantum-resistant encryption algorithms in Chrome 116 to set up symmetric keys in TLS connections. It's also part of broader efforts to switch to cryptographic algorithms that can withstand quantum attacks in the future, necessitating the need to incorporate such technologies early on to facilitate a gradual rollout. "Fortunately, with the rece...

Multiple critical security flaws have been reported in  Ivanti Avalanche , an enterprise mobile device management solution that's used by 30,000 organizations. The vulnerabilities, collectively tracked as  CVE-2023-32560  (CVSS score: 9.8), are stack-based buffer overflows in Ivanti Avalanche WLAvanacheServer.exe v6.4.0.0. Cybersecurity company Tenable  said  the shortcomings are the result of buffer overflows arising as a consequence of processing specific data types. An unauthenticated remote attacker can specify a long hex string or long type 9 item to overflow the buffer, it noted. Successful exploitation of both issues could be exploited by a remote adversary to achieve code execution or a system crash. Stack-based buffer overflow vulnerabilities  occur when  the buffer being overwritten is in the stack, leading to a scenario where program execution can be altered to run arbitrary code with elevated privileges. Ivanti has released  Av...

Nearly 2,000 Citrix NetScaler instances have been compromised with a backdoor by weaponizing a recently disclosed critical security vulnerability as part of a large-scale attack. "An adversary appears to have exploited CVE-2023-3519 in an automated fashion, placing web shells on vulnerable NetScalers to gain persistent access," NCC Group  said  in an advisory released Tuesday. "The adversary can execute arbitrary commands with this webshell, even when a NetScaler is patched and/or rebooted." CVE-2023-3519 refers to a critical code injection vulnerability impacting NetScaler ADC and Gateway servers that could lead to unauthenticated remote code execution. It was patched by Citrix last month. The development comes a week after the Shadowserver Foundation  said  it identified close to 7,000 vulnerable, unpatched NetScaler ADC and Gateway instances online and the flaw is being abused to drop PHP web shells on vulnerable servers for remote access. A follow-up anal...

Threat actors' use of Cloudflare R2 to host phishing pages has witnessed a 61-fold increase over the past six months. "The majority of the phishing campaigns target Microsoft login credentials, although there are some pages targeting Adobe, Dropbox, and other cloud apps," Netskope security researcher Jan Michael  said . Cloudflare R2 , analogous to Amazon Web Service S3, Google Cloud Storage, and Azure Blob Storage, is a data storage service for the cloud. The development comes as the total number of cloud apps from which malware downloads originate has  increased to 167 , with Microsoft OneDrive, Squarespace, GitHub, SharePoint, and Weebly taking the top five spots. The phishing campaigns identified by Netskope not only abuse Cloudflare R2 to distribute static phishing pages, but also leverage the company's  Turnstile  offering, a CAPTCHA replacement, to place such pages behind anti-bot barriers to evade detection. In doing so, it prevents online scanners lik...

Four security vulnerabilities in the ScrutisWeb ATM fleet monitoring software made by Iagona could be exploited to remotely break into ATMs, upload arbitrary files, and even reboot the terminals. The shortcomings were  discovered  by the Synack Red Team (SRT) following a client engagement. The issues have been addressed in ScrutisWeb version 2.1.38. "Successful exploitation of these vulnerabilities could allow an attacker to upload and execute arbitrary files," the U.S. Cybersecurity and Infrastructure Security Agency (CISA)  said  in an advisory published last month. ScrutisWeb  is a web browser-based solution for monitoring banking and retail ATM fleets, including gleaning information system status, detecting low paper alerts, shutting down or restarting a terminal, and remotely modifying data. Details of the four flaws are as follows - CVE-2023-33871  (CVSS score: 7.5) - A directory traversal vulnerability that could allow an unauthenticated user...

The threat actors behind the Monti ransomware have resurfaced after a two-month break with a new Linux version of the encryptor in its attacks targeting government and legal sectors. Monti  emerged  in June 2022, weeks after the Conti ransomware group shut down its operations, deliberately imitating the tactics and tools associated with the latter, including its leaked source code. Not anymore. The new version, per Trend Micro, is a departure of sorts, exhibiting significant changes from its other Linux-based predecessors. "Unlike the earlier variant, which is primarily based on the leaked Conti source code, this new version employs a different encryptor with additional distinct behaviors," Trend Micro researchers Nathaniel Morales and Joshua Paul Ignacio  said . A  BinDiff analysis  has revealed that while the older iterations had a 99% similarity rate with Conti, the latest version has only a 29% similarity rate, suggesting an overhaul. Some of the cruc...

The just-released BlackBerry Global Threat Intelligence Report reveals a 40% increase in cyberattacks against government and public service organizations versus the previous quarter. This includes public transit, utilities, schools, and other government services we rely on daily. With limited resources and often immature cyber defense programs, these publicly funded organizations are struggling against the double-pronged threat of attacks from both nation-states and the criminal underground.  These are just a few of the findings contained in the  latest edition  of BlackBerry's quarterly cybersecurity benchmarking guide.

Account holders of over numerous financial institutions in Thailand, Indonesia, Vietnam, the Philippines, and Peru are being targeted by an Android banking malware called  Gigabud RAT . "One of Gigabud RAT's unique features is that it doesn't execute any malicious actions until the user is authorized into the malicious application by a fraudster, [...] which makes it harder to detect," Group-IB researchers Pavel Naumov and Artem Grischenko  said . "Instead of using HTML overlay attacks, Gigabud RAT gathers sensitive information primarily through screen recording." Gigabud RAT was  first documented  by Cyble in January 2023 after it was spotted impersonating bank and government apps to siphon sensitive data. It's known to be active in the wild since at least July 2022. The Singapore-based company said it also identified a second variant of the malware minus the RAT capabilities. Dubbed Gigabud.Loan, it comes under the guise of a loan application that...

A "staggering" 120,000 computers infected by stealer malware have credentials associated with cybercrime forums, many of them belonging to malicious actors. The  findings  come from Hudson Rock, which analyzed data collected from computers compromised between 2018 to 2023. "Hackers around the world infect computers opportunistically by promoting results for fake software or through YouTube tutorials directing victims to download infected software," Hudson Rock CTO Alon Gal told The Hacker News. "It is not a case of the threat actor infecting his own computer, it is that out of the 14,500,000 computers we have in our cybercrime database, some of them happen to be hackers that  accidentally got infected ." Data retrieved from machines compromised by stealer malware is often expansive and wide-ranging, enabling the real-world identities of hackers to be discovered based on indicators such as credentials, addresses, phone numbers, computer names, and IP a...
