Details have been disclosed about a now-addressed critical vulnerability in Microsoft's  Azure Automation  service that could have permitted unauthorized access to other Azure customer accounts and take over control. "This attack could mean full control over resources and data belonging to the targeted account, depending on the permissions assigned by the customer," Orca Security researcher Yanir Tsarimi  said  in a report published Monday. The flaw potentially put several entities at risk, including an unnamed telecommunications company, two car manufacturers, a banking conglomerate, and big four accounting firms, among others, the Israeli cloud infrastructure security company added. The Azure Automation service  allows  for process automation, configuration management, and handling operating system updates within a defined maintenance window across Azure and non-Azure environments. Dubbed " AutoWarp ," the issue affects all users of the Azure Automa...

Researchers have disclosed details of critical security vulnerabilities in TerraMaster network-attached storage (TNAS) devices that could be chained to attain unauthenticated remote code execution with the highest privileges. The issues reside in TOS, an abbreviation for TerraMaster Operating System, and "can grant unauthenticated attackers access to the victim's box simply by knowing the IP address," Ethiopian cyber security research firm Octagon Networks ' Paulos Yibelo said in a statement shared with The Hacker News. TOS is the  operating system  designed for TNAS appliances, enabling users to manage storage, install applications, and backup data. Following responsible disclosure, the flaws were patched in  TOS version 4.2.30  released last week on March 1, 2022. One of the issues, tracked as CVE-2022-24990, concerns a case of information leak in a component called "webNasIPS," resulting in the exposure of TOS firmware version, the default gateway in...

Cyber-attacks keep increasing and evolving but, regardless of the degree of complexity used by hackers to gain access, get a foothold, cloak their malware, execute their payload or exfiltrate data, their attack will begin with reconnaissance. They will do their utmost to uncover exposed assets and probe their target's attack surface for gaps that can be used as entry points. So, the first line of defense is to limit the potentially useful information available to a potential attacker as much as possible. As always, the tug of war between operational necessity and security concerns needs to be taken into account, which requires a better understanding of the type of information typically leveraged. What information are hackers looking for during recon? When running recon on an organization, hackers – whether white or black hats - are "casing a joint." To plan their attack, they will try and uncover as much information as possible about: Your infrastructure The types ...

Ukraine's Computer Emergency Response Team (CERT-UA) warned of new phishing attacks aimed at its citizens by leveraging compromised email accounts belonging to three different Indian entities with the goal of compromising their inboxes and stealing sensitive information. The agency  cautioned  that the emails arrive with the subject line "Увага" (meaning "Attention") and claim to be from a domestic email service called Ukr.net, when in actuality, the email address of the sender is "muthuprakash.b@tvsrubber[.]com." The messages purportedly warn the recipients of an unauthorized attempt to log in to their accounts from an IP address based out of the eastern Ukrainian city of Donetsk, further prompting them to click on a link to change their passwords with immediate effect. "After following the link and entering the password, it gets to the attackers," CERT-UA noted in a Facebook post over the weekend. "In this way, they gain access to ...

The threat actor behind a nascent Android banking trojan named  SharkBot  has managed to evade Google Play Store security barriers by masquerading as an antivirus app. SharkBot, like its malware counterparts  TeaBot ,  FluBot , and  Oscorp  (UBEL), belongs to a category of financial trojans capable of siphoning credentials to initiate money transfers from compromised devices by circumventing multi-factor authentication mechanisms. It first emerged on the scene in November 2021. Where SharkBot stands apart is in its ability to carry out the unauthorized transactions via Automatic Transfer Systems (ATS), which stands in contrast to TeaBot, which requires a live operator to interact with the infected devices to conduct the malicious activities. "The ATS features allow the malware to receive a list of events to be simulated, and they will be simulated in order to do the money transfers," Alberto Segura and Rolf Govers, malware analysts at cybersecurity fir...

Mozilla has pushed out-of-band  software updates  to its Firefox web browser to contain two high-impact security vulnerabilities, both of which it says are being actively exploited in the wild. Tracked as CVE-2022-26485 and CVE-2022-26486, the zero-day flaws have been described as  use-after-free issues  impacting the Extensible Stylesheet Language Transformations ( XSLT ) parameter processing and the  WebGPU  inter-process communication ( IPC ) Framework. XSLT is an XML-based language used for the conversion of XML documents into web pages or PDF documents, whereas WebGPU is an emerging web standard that's been billed as a successor to the current WebGL JavaScript graphics library. The description of the two flaws is below – CVE-2022-26485  – Removing an XSLT parameter during processing could lead to an exploitable use-after-free CVE-2022-26486  – An unexpected message in the WebGPU IPC framework could lead to a use-after-free and exploit...

Details have emerged about a now-patched high-severity vulnerability in the Linux kernel that could potentially be abused to escape a container in order to execute arbitrary commands on the container host. The shortcoming resides in a Linux kernel feature called  control groups , also referred to as cgroups version 1 (v1), which allows processes to be organized into hierarchical groups, thereby making it possible to limit and monitor the usage of resources such as CPU, memory, disk I/O, and network. Tracked as  CVE-2022-0492  (CVSS score: 7.0), the  issue   concerns  a  case  of  privilege escalation  in the cgroups v1 release_agent functionality, a script that's executed following the termination of any process in the cgroup. "The issue stands out as one of the simplest Linux privilege escalations discovered in recent times: The Linux kernel mistakenly exposed a privileged operation to unprivileged users," Unit 42 researcher Yuval A...
