In a continuing sign that threat actors are adapting well to a  post-macro world , it has emerged that the use of Microsoft OneNote documents to deliver malware via phishing attacks is on the rise. Some of the notable malware families that are being distributed using this method include AsyncRAT,  RedLine Stealer , Agent Tesla,  DOUBLEBACK , Quasar RAT, XWorm,  Qakbot ,  BATLOADER , and  FormBook . Enterprise security firm Proofpoint said it detected over 50 campaigns leveraging OneNote attachments in the month of January 2023 alone. In some instances, the email phishing lures contain a OneNote file, which, in turn, embeds an HTA file that invokes a PowerShell script to retrieve a malicious binary from a remote server. Other scenarios entail the execution of a rogue VBScript that's embedded within the OneNote document and concealed behind an image that appears as a seemingly harmless button. The VBScript, for its part, is designed to drop a PowerShell script to run DOUBLEBACK

The Iranian nation-state hacking group known as  OilRig  has continued to target government organizations in the Middle East as part of a cyber espionage campaign that leverages a new backdoor to exfiltrate data. "The campaign abuses legitimate but compromised email accounts to send stolen data to external mail accounts controlled by the attackers," Trend Micro researchers Mohamed Fahmy, Sherif Magdy, and Mahmoud Zohdy  said . While the technique in itself is not unheard of, the development marks the first time OilRig has adopted it in its playbook, indicating the continued evolution of its methods to bypass security protections. The advanced persistent threat (APT) group, also referred to as APT34, Cobalt Gypsy, Europium, and Helix Kitten, has been  documented  for its targeted phishing attacks in the Middle East since at least 2014. Linked to Iran's Ministry of Intelligence and Security (MOIS), the group is known to use a diverse toolset in its operations, with re

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,

Cybersecurity is quickly becoming one of the most significant growth drivers for Managed Service Providers (MSPs). That's the main insight from a  recent study  from Lumu: in North America, more than 80% of MSPs cite cybersecurity as a primary growth driver of their business. Service providers have a huge opportunity to expand their business and win new customers by developing their cybersecurity offerings. This hardly comes as a surprise since the demand for cybersecurity is in full swing among SMBs and larger enterprises. According to  Gartner , "by 2025, 60% of organizations will use cybersecurity risk as a primary determinant in conducting third-party transactions and business engagements." This means that the perception around security is transforming: from liability, it's becoming a powerful business driver. Of course, cybersecurity continues to evolve at a very rapid pace, with threats emerging every day and the stakes getting higher. This alone can fuel the

Atlassian has released fixes to resolve a critical security flaw in Jira Service Management Server and Data Center that could be abused by an attacker to pass off as another user and gain unauthorized access to susceptible instances. The  vulnerability  is tracked as  CVE-2023-22501  (CVSS score: 9.4) and has been described as a case of broken authentication with low attack complexity. "An authentication vulnerability was discovered in Jira Service Management Server and Data Center which allows an attacker to impersonate another user and gain access to a Jira Service Management instance under certain circumstances," Atlassian  said . "With write access to a User Directory and outgoing email enabled on a Jira Service Management instance, an attacker could gain access to signup tokens sent to users with accounts that have never been logged into." The tokens, Atlassian noted, can be obtained in either of the two scenarios - If the attacker is included on Jira i

F5 has warned of a high-severity flaw impacting BIG-IP appliances that could lead to denial-of-service (DoS) or arbitrary code execution. The issue is rooted in the iControl Simple Object Access Protocol ( SOAP ) interface and affects the following versions of BIG-IP - 13.1.5 14.1.4.6 - 14.1.5 15.1.5.1 - 15.1.8 16.1.2.2 - 16.1.3, and 17.0.0 "A format string vulnerability exists in iControl SOAP that allows an authenticated attacker to crash the iControl SOAP CGI process or, potentially execute arbitrary code," the company  said  in an advisory. "In appliance mode BIG-IP, a successful exploit of this vulnerability can allow the attacker to cross a security boundary." Tracked as CVE-2023-22374 (CVSS score: 7.5/8.5), security researcher Ron Bowes of Rapid7 has been credited with discovering and reporting the flaw on December 6, 2022. Given that the iCOntrol SOAP interface runs as root, a successful exploit could permit a threat actor to remotely trigger co

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on February 2  added  two security flaws to its Known Exploited Vulnerabilities (KEV) Catalog, citing evidence of active exploitation. The first of the two vulnerabilities is  CVE-2022-21587  (CVSS score: 9.8), a critical issue impacting versions 12.2.3 to 12.2.11 of the Oracle Web Applications Desktop Integrator product. "Oracle E-Business Suite contains an unspecified vulnerability that allows an unauthenticated attacker with network access via HTTP to compromise Oracle Web Applications Desktop Integrator," CISA  said . The issue was addressed by Oracle as part of its Critical Patch Update released in October 2022. Not much is known about the nature of the attacks exploiting the vulnerability, but the development follows the publication of a proof-of-concept (PoC) by cybersecurity firm Viettel on January 16, 2023. The second security flaw to be added to the KEV catalog is  CVE-2023-22952  (CVSS score:

The State Cyber Protection Centre (SCPC) of Ukraine has called out the Russian state-sponsored threat actor known as  Gamaredon  for its targeted cyber attacks on public authorities and critical information infrastructure in the country. The advanced persistent threat, also known as Actinium, Armageddon, Iron Tilden, Primitive Bear, Shuckworm, Trident Ursa, and UAC-0010, has a  track record  of  striking   Ukrainian entities  dating as far back as 2013. "UAC-0010 group's ongoing activity is characterized by a multi-step download approach and executing payloads of the spyware used to maintain control over infected hosts," the SCPC  said . "For now, the UAC-0010 group uses  GammaLoad and GammaSteel  spyware in their campaigns." GammaLoad is a VBScript dropper malware engineered to download next-stage VBScript from a remote server. GammaSteel is a PowerShell script that's capable of conducting reconnaissance and executing additional commands. The goal of t

Over the past few years, cybersecurity has become a major concern for businesses around the globe.

A new intelligence gathering campaign linked to the prolific North Korean state-sponsored Lazarus Group leveraged known security flaws in unpatched Zimbra devices to compromise victim systems. That's according to Finnish cybersecurity company WithSecure (formerly F-Secure), which codenamed the incident No Pineapple in reference to an error message that's used in one of the backdoors. Targets of the malicious operation included a healthcare research organization in India, the chemical engineering department of a leading research university, as well as a manufacturer of technology used in the energy, research, defense, and healthcare sectors, suggesting an attempt to breach the supply chain. Roughly 100GB of data is estimated to have been exported by the hacking crew following the compromise of an unnamed customer, with the digital break-in likely taking place in the third quarter of 2022. "The threat actor gained access to the network by exploiting a vulnerable Zimbra

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.,

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
