Microsoft on Tuesday said it addressed an authentication bypass vulnerability in  Jupyter Notebooks  for Azure Cosmos DB that enabled full read and write access. The tech giant said the problem was introduced on August 12, 2022, and rectified worldwide on October 6, 2022, two days after responsible disclosure from Orca Security, which dubbed the flaw  CosMiss . "In short, if an attacker had knowledge of a Notebook's 'forwardingId,' which is the UUID of the Notebook Workspace, they would have had full permissions on the Notebook without having to authenticate, including read and write access, and the ability to modify the file system of the container running the notebook," researchers Lidor Ben Shitrit and Roee Sagi said. This container modification could ultimately pave the way for obtaining remote code execution in the Notebook container by overwriting a Python file associated with the  Cosmos DB Explorer  to spawn a reverse shell.

The Chinese state-sponsored threat actor known as Stone Panda has been observed employing a new stealthy infection chain in its attacks aimed at Japanese entities. Targets include media, diplomatic, governmental and public sector organizations, and think-tanks in Japan, according to  twin   reports  published by Kaspersky. Stone Panda , also called  APT10 , Bronze Riverside, Cicada, and Potassium, is a cyber  espionage group  known for its intrusions against organizations identified as strategically significant to China. The threat actor is believed to have been active since at least 2009. The group has also been linked to attacks using malware families like SigLoader, SodaMaster , and a web shell called Jackpot against multiple Japanese domestic organizations since April 2021, per cybersecurity firm Trend Micro, which is tracking the group under the name Earth Tengshe . The latest set of attacks, observed between March and June 2022, involve the use...

Linus Torvalds, the creator of Linux and Git, has his own law in software development, and it goes like this: " given enough eyeballs, all bugs are shallow ." This phrase puts the finger on the very principle of open source: the more, the merrier - if the code is easily available for anyone and everyone to fix bugs, it's pretty safe. But is it? Or is the saying "all bugs are shallow" only true for  shallow  bugs and not ones that lie deeper? It turns out that security flaws in open source can be harder to find than we thought. Emil Wåreus, Head of R&D at  Debricked , took it upon himself to look deeper into the community's performance. As the data scientist he is, he, of course, asked the data:  how good is the open source community at finding vulnerabilities in a timely manner ? The thrill of the (vulnerability) hunt Finding open source vulnerabilities is typically done by the maintainers of the open source project, users, auditors, or external secur...

IT service management software platform ConnectWise has released Software patches for a critical security vulnerability in Recover and R1Soft Server Backup Manager (SBM). The issue,  characterized  as a "neutralization of Special Elements in Output Used by a Downstream Component," could be abused to result in the execution of remote code or disclosure of sensitive information. ConnectWise's advisory notes that the flaw affects Recover v2.9.7 and earlier, as well as R1Soft SBM v6.16.3 and earlier, are impacted by the critical flaw. At its core, the issue is tied to an upstream authentication bypass vulnerability in the ZK open source Ajax web application framework ( CVE-2022-36537 ), which was initially patched in May 2022. "Affected ConnectWise Recover SBMs have automatically been updated to the latest version of Recover (v2.9.9)," the company  said , urging customers to upgrade to  SBM v6.16.4  shipped on October 28, 2022. Cybersecurity firm Huntress...

The threat actor behind the Fodcha distributed denial-of-service (DDoS) botnet has resurfaced with new capabilities, researchers reveal. This includes changes to its communication protocol and the ability to extort cryptocurrency payments in exchange for stopping the DDoS attack against a target, Qihoo 360's Network Security Research Lab  said  in a report published last week. Fodcha  first came to light  earlier this April, with the malware propagating through known vulnerabilities in Android and IoT devices as well as weak Telnet or SSH passwords. The cybersecurity company said that Fodcha has evolved into a large-scale botnet with over 60,000 active nodes and 40 command-and-control (C2) domains that can "easily generate more than 1 Tbps traffic." Peak activity is said to have occurred on October 11, 2022, when the malware targeted 1,396 devices in a single day. The top countries singled out by the botnet since late June 2022 comprises China, the U.S., Singa...
