Cybersecurity researchers are warning of publicly exposed Kubernetes configuration secrets that could put organizations at risk of supply chain attacks. “These encoded Kubernetes configuration secrets were uploaded to public repositories,” Aqua security researchers Yakir Kadkoda and Assaf Morag  said  in a new research published earlier this week. Some of those impacted include two top blockchain companies and various other fortune-500 companies, according to the cloud security firm, which leveraged the GitHub API to fetch all entries containing .dockerconfigjson and .dockercfg types that  store credentials  for accessing a container image registry. Of the 438 records that potentially held valid credentials for registries, 203 records – about 46% – contained valid credentials that provided access to the respective registries. Ninety-three of the passwords were manually set by individuals, as opposed to the 345 that were computer-generated. “In the majority of ...

A new phishing attack has been observed leveraging a Russian-language Microsoft Word document to deliver malware capable of harvesting sensitive information from compromised Windows hosts. The activity has been attributed to a threat actor called Konni , which is assessed to share overlaps with a North Korean cluster tracked as Kimsuky (aka APT43). "This campaign relies on a remote access trojan (RAT) capable of extracting information and executing commands on compromised devices," Fortinet FortiGuard Labs researcher Cara Lin  said  in an analysis published this week. The  cyber espionage   group  is notable for its  targeting of Russia , with the modus operandi involving the use of spear-phishing emails and malicious documents as entry points for their attacks. Recent attacks documented by Knowsec and ThreatMon have leveraged the  WinRAR vulnerability  (CVE-2023-38831) as well as obfuscated Visual Basic scripts to drop  Konni RAT ...

Delivery- and shipping-themed email messages are being used to deliver a sophisticated malware loader known as  WailingCrab . "The malware itself is split into multiple components, including a loader, injector, downloader and backdoor, and successful requests to C2-controlled servers are often necessary to retrieve the next stage," IBM X-Force researchers Charlotte Hammond, Ole Villadsen, and Kat Metrick  said . WailingCrab, also called WikiLoader, was  first documented  by Proofpoint in August 2023, detailing campaigns targeting Italian organizations that used the malware to ultimately deploy the Ursnif (aka Gozi) trojan. It was spotted in the wild in late December 2022. The malware is the handiwork of a threat actor known as TA544, which is also tracked as Bamboo Spider and Zeus Panda. IBM X-Force has named the cluster Hive0133. Actively maintained by its operators, the malware has been observed incorporating features that prioritize stealth and allows it to ...

Modern security tools continue to improve in their ability to defend organizations’ networks and endpoints against cybercriminals. But the bad actors still occasionally find a way in. Security teams must be able to stop threats and restore normal operations as quickly as possible. That’s why it’s essential that these teams not only have the right tools but also understand how to effectively respond to an incident. Resources like an  incident response template  can be customized to define a plan with roles and responsibilities, processes and an action item checklist. But preparations can’t stop there. Teams must continuously train to adapt as threats rapidly evolve. Every security incident must be harnessed as an educational opportunity to help the organization better prepare for — or even prevent — future incidents. SANS Institute defines a framework with six steps to a successful IR. Preparation Identification Containment Eradication Recovery Lessons learned Whil...

An active malware campaign is leveraging two zero-day vulnerabilities with remote code execution (RCE) functionality to rope routers and video recorders into a Mirai-based distributed denial-of-service (DDoS) botnet. “The payload targets routers and network video recorder (NVR) devices with default admin credentials and installs Mirai variants when successful,” Akamai  said  in an advisory published this week. Details of the flaws are currently under wraps to allow the two vendors to publish patches and prevent other threat actors from abusing them. The fixes for one of the vulnerabilities are expected to be shipped next month. The attacks were first discovered by the web infrastructure and security company against its honeypots in late October 2023. The perpetrators of the attacks have not been identified as yet. The botnet, which has been codenamed InfectedSlurs due to the use of racial and offensive language in the command-and-control (C2) servers and hard-coded strin...
