At least 1,200 Redis database servers worldwide have been corralled into a botnet using an "elusive and severe threat" dubbed HeadCrab since early September 2021. "This advanced threat actor utilizes a state-of-the-art, custom-made malware that is undetectable by agentless and traditional anti-virus solutions to compromise a large number of Redis servers," Aqua security researcher Asaf Eitani  said  in a Wednesday report. A significant concentration of infections has been recorded in China, Malaysia, India, Germany, the U.K., and the U.S. to date. The origins of the threat actor are presently unknown. The findings come two months after the cloud security firm shed light on a Go-based malware codenamed  Redigo  that has been found compromising Redis servers. The attack is designed to target Redis servers that are exposed to the internet, followed by issuing a  SLAVEOF command  from another Redis server that's already under the adversary's control. In

Cybersecurity researchers have disclosed details of two security flaws in the open source  ImageMagick software  that could potentially lead to a denial-of-service (DoS) and information disclosure. The two issues, which were identified by Latin American cybersecurity firm Metabase Q in version 7.1.0-49, were  addressed  in ImageMagick  version 7.1.0-52 , released in November 2022. A brief description of the flaws is as follows - CVE-2022-44267  - A DoS vulnerability that arises when parsing a PNG image with a filename that's a single dash ("-") CVE-2022-44268  - An information disclosure vulnerability that could be exploited to read arbitrary files from a server when parsing an image That said, an attacker must be able to upload a malicious image to a website using ImageMagick so as to weaponize the flaws remotely. The specially crafted image, for its part, can be created by inserting a  text chunk  that specifies some metadata of the attacker's choice (e.g.,

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

A new attack campaign has been targeting the gaming and gambling sectors since at least September 2022, just as the ICE London 2023 gaming industry trade fair event is scheduled to kick off next week. Israeli cybersecurity company Security Joes is tracking the activity cluster under the name  Ice Breaker , stating the intrusions employ clever social engineering tactics to deploy a JavaScript backdoor. The attack sequence proceeds as follows: The threat actor poses as a customer while initiating a conversation with a support agent of a gaming company under the pretext of having account registration issues. The adversary then urges the individual on the other end to open a screenshot image hosted on Dropbox. Security Joes said that the threat actor is "well-aware of the fact that the customer service is human-operated." Clicking the purported screenshot link sent in the chat leads to the retrieval of an LNK payload or, alternatively, a VBScript file as a backup option,

A new exploit has been devised to "unenroll" enterprise- or school-managed Chromebooks from administrative control. Enrolling ChromeOS devices makes it possible to enforce device policies as set by the organization via the  Google Admin console , including the features that are available to users. "Each enrolled device complies with the policies you set until you wipe or deprovision it," Google  states  in its documentation. That's where the  exploit  – dubbed Shady Hacking 1nstrument Makes Machine Enrollment Retreat aka  SH1MMER  – comes in, allowing users to bypass these admin restrictions. The method is also a reference to shim, a Return Merchandise Authorization (RMA) disk image used by service center technicians to reinstall the operating system and run diagnosis and repair programs. The Google-signed  shim image  is a "combination of existing Chrome OS  factory bundle  components" – namely a release image, a toolkit, and the firmware, amon

Container technology has gained traction among businesses due to the increased efficiency it provides. In this regard, organizations widely use Kubernetes for deploying, scaling, and managing containerized applications. Organizations should audit Kubernetes to ensure compliance with regulations, find anomalies, and identify security risks. The Wazuh open source platform plays a critical role in monitoring Kubernetes and other components of an organization's infrastructure. What is Kubernetes? Kubernetes is an open source container management solution that automates the deployment and scaling of containers and also manages the life cycle of containers. It organizes containers into logical units for simple management and discovery. Kubernetes extends how we scale containerized applications so that we may use a truly persistent infrastructure. You can build cloud-native applications based on microservices with Kubernetes. Enthusiasts view Kubernetes as the cornerstone of application m

The Brazilian threat actors behind an advanced and modular point-of-sale (PoS) malware known as  Prilex  have reared their head once again with new updates that allow it to block contactless payment transactions. Russian cybersecurity firm Kaspersky  said  it detected three versions of Prilex (06.03.8080, 06.03.8072, and 06.03.8070) that are capable of targeting NFC-enabled credit cards, taking its criminal scheme a notch higher. Having evolved out of ATM-focused malware into PoS malware over the years since going operational in 2014, the threat actor has steadily incorporated new features that are designed to facilitate credit card fraud, including a technique called  GHOST transactions . While contactless payments have taken off in a big way, in part due to the COVID-19 pandemic, the underlying motive behind the new functionality is to disable the feature so as to force the user to insert the card into the PIN pad. To that end, the latest version of Prilex, which Kaspersky disc

Microsoft on Tuesday said it took steps to disable fake Microsoft Partner Network (MPN) accounts that were used for creating malicious  OAuth  applications as part of a phishing campaign designed to breach organizations' cloud environments and steal email. "The applications created by these fraudulent actors were then used in a consent phishing campaign, which tricked users into granting permissions to the fraudulent apps," the tech giant  said . "This phishing campaign targeted a subset of customers primarily based in the U.K. and Ireland." Consent phishing is a  social engineering attack  wherein users are tricked into granting permissions to malicious cloud applications, which can then be weaponized to gain access to legitimate cloud services and sensitive user data. The Windows maker said it became aware of the campaign on December 15, 2022. It has since alerted affected customers via email, with the company noting that the threat actors abused the conse

Two more supply chain security flaws have been disclosed in AMI MegaRAC Baseboard Management Controller (BMC) software, nearly two months after  three security vulnerabilities  were brought to light in the same product. Firmware security firm Eclypsium  said  the two shortcomings were held back until now to provide AMI additional time to engineer appropriate mitigations. The issues, collectively tracked as  BMC&C , could act as a springboard for cyber attacks, enabling threat actors to obtain remote code execution and unauthorized device access with superuser permissions. The two new flaws in question are as follows - CVE-2022-26872  (CVSS score: 8.3) - ​​Password reset interception via API CVE-2022-40258  (CVSS score: 5.3) - Weak password hashes for Redfish and API Specifically, MegaRAC has been found to use the MD5 hashing algorithm with a global salt for older devices, or  SHA-512 with per user salts  on newer appliances, potentially allowing a threat actor to crack th

Do you know where your secrets are? If not, I can tell you: you are not alone. Hundreds of CISOs, CSOs, and security leaders, whether from small or large companies, don't know either. No matter the organization's size, the certifications, tools, people, and processes: secrets are not visible in 99% of cases. It might sound ridiculous at first: keeping secrets is an obvious first thought when thinking about security in the development lifecycle. Whether in the cloud or on-premise, you know that your secrets are safely stored behind hard gates that few people can access. It is not just a matter of common sense since it's also an essential compliance requirement for security audits and certifications. Developers working in your organization are well-aware that secrets should be handled with special care. They have put in place specific tools and procedures to correctly create, communicate, and rotate human or machine credentials. Still, do you know where your secrets are?
