Multiple vulnerabilities have been disclosed in Checkmk IT Infrastructure monitoring software that could be chained together by an unauthenticated, remote attacker to fully take over affected servers.  "These vulnerabilities can be chained together by an unauthenticated, remote attacker to gain code execution on the server running Checkmk version 2.1.0p10 and lower," SonarSource researcher Stefan Schiller  said  in a technical analysis. Checkmk's open source edition of the monitoring tool is based on  Nagios Core  and offers integrations with  NagVis  for the visualization and generation of topological maps of infrastructures, servers, ports, and processes. According to its Munich-based developer tribe29 GmbH, its Enterprise and Raw editions are used by  over 2,000 customers , including Airbus, Adobe, NASA, Siemens, Vodafone, and others. The four vulnerabilities, which consist of two Critical and two Medium severity bugs, are as follows - ...

A set of four Android apps released by the same developer has been discovered directing victims to malicious websites as part of an adware and information-stealing campaign. The apps, published by a developer named  Mobile apps Group  and currently available on the Play Store, have been collectively downloaded over one million times. According to  Malwarebytes , the websites are designed to generate revenues through pay-per-click ads, and worse, prompt users to install cleaner apps on their phones with the goal of deploying additional malware. The list of apps is as follows - Bluetooth App Sender (com.bluetooth.share.app) - 50,000+ downloads Bluetooth Auto Connect (com.bluetooth.autoconnect.anybtdevices) - 1,000,000+ downloads Driver: Bluetooth, Wi-Fi, USB (com.driver.finder.bluetooth.wifi.usb) - 10,000+ downloads Mobile transfer: smart switch (com.mobile.faster.transfer.smart.switch) - 1,000+ downloads It's no surprise that malicious apps have  devised ...

Raccoon Stealer is back on the news again. US officials arrested Mark Sokolovsky, one of the malware actors behind this program. In July 2022, after several months of the shutdown, a Raccoon Stealer V2 went viral. Last week, the Department of Justice's press release stated that the malware collected 50 million credentials. This article will give a quick guide to the latest info stealer's version. What is Raccoon infostealer V2? Raccoon Stealer  is a kind of malware that steals various data from an infected computer. It's quite a basic malware, but hackers have made Raccoon popular with excellent service and simple navigation.  In 2019, Raccoon infostealer was one of the most discussed malware. In exchange for $75 per week and $200 per month, cybercriminals sold this simple but versatile info stealer as a MaaS. The malware was successful in attacking a number of systems. In March 2022, however, threat authors ceased to operate.  An updated version of this malware was...

A previously undocumented Android spyware campaign has been found striking Persian-speaking individuals by masquerading as a seemingly harmless VPN application. Russian cybersecurity firm Kaspersky is tracking the campaign under the moniker  SandStrike . It has not been attributed to any particular threat group. "SandStrike is distributed as a means to access resources about the  Bahá'í religion  that are banned in Iran," the company noted in its  APT trends report  for the third quarter of 2022. While the app is ostensibly designed to provide victims with a VPN connection to bypass the ban, it's also configured to covertly siphon data from the victims' devices, such as call logs, contacts, and even connect to a remote server to fetch additional commands. The booby-trapped VPN service, while fully functional, is said to be distributed via a Telegram channel controlled by the adversary. Links to the channel are also advertised on fabricated social media ac...

File hosting service Dropbox on Tuesday disclosed that it was the victim of a phishing campaign that allowed unidentified threat actors to gain unauthorized access to 130 of its source code repositories on GitHub. "These repositories included our own copies of third-party libraries slightly modified for use by Dropbox, internal prototypes, and some tools and configuration files used by the security team," the company  revealed  in an advisory. The breach resulted in the access of some API keys used by Dropbox developers as well as "a few thousand names and email addresses belonging to Dropbox employees, current and past customers, sales leads, and vendors." It, however, stressed that the repositories did not contain source code related to its core apps or infrastructure. Dropbox, which offers cloud storage, data backup, and document signing services, among others, has over 17.37 million paying users and 700 million registered users as of  August 2022 . The di...

The OpenSSL project has rolled out fixes to contain two high-severity flaws in its widely used cryptography library that could result in a denial-of-service (DoS) and remote code execution. The issues, tracked as  CVE-2022-3602 and CVE-2022-3786 , have been described as buffer overrun vulnerabilities that can be triggered during X.509 certificate verification by supplying a specially-crafted email address. "In a TLS client, this can be triggered by connecting to a malicious server," OpenSSL said in an advisory for CVE-2022-3786. "In a TLS server, this can be triggered if the server requests client authentication and a malicious client connects." OpenSSL is an  open source implementation  of the SSL and TLS protocols used for secure communication and is baked into several operating systems and a wide range of software . Versions 3.0.0 through 3.0.6 of the library are affected by the new flaws, which has been remediated in version 3.0.7. It's worth noting tha...

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. Successful exploitatio...
