Russia has detained a South Korean national for the first time on cyber espionage charges and transferred from Vladivostok to Moscow for further investigation. The development was  first reported  by Russian news agency TASS. “During the investigation of an espionage case, a South Korean citizen Baek Won-soon was identified and detained in Vladivostok, and put into custody under a court order,” an unnamed source was quoted as saying. Won-soon has been accused of handing over classified “top secret” information to unnamed foreign intelligence agencies. According to the agency, Won-soon was detained in Vladivostok earlier this year and shifted to Moscow late last month. He is said to be currently at the Lefortovo pretrial detention center. His arrest has been extended for another three months, until June 15, 2024. The  detention center  is currently also the  place  where American journalist Evan Gershkovich is  being held , awaiting trial on susp...

Users in Brazil are the target of a new banking trojan known as  CHAVECLOAK  that's propagated via phishing emails bearing PDF attachments. "This intricate attack involves the PDF downloading a ZIP file and subsequently utilizing DLL side-loading techniques to execute the final malware," Fortinet FortiGuard Labs researcher Cara Lin  said . The attack chain involves the use of contract-themed DocuSign lures to trick users into opening PDF files containing a button to read and sign the documents. In reality, clicking the button leads to the retrieval of an installer file from a remote link that's shortened using the Goo.su URL shortening service. Present within the installer is an executable named "Lightshot.exe" that leverages DLL side-loading to load "Lightshot.dll," which is the CHAVECLOAK malware that facilitates the theft of sensitive information. This includes gathering system metadata and running checks to determine whether the compromis...

As the shift of IT infrastructure to cloud-based solutions celebrates its 10-year anniversary, it becomes clear that traditional on-premises approaches to data security are becoming obsolete. Rather than protecting the endpoint, DLP solutions need to refocus their efforts to where corporate data resides - in the browser. A new guide by LayerX titled "On-Prem is Dead. Have You Adjusted Your Web DLP Plan?" ( download here ) dives into this transition, detailing its root cause, possible solution paths forward and actionable implementation examples. After reading the guide, security and IT professionals will be equipped with the relevant information they need to update and upgrade their DLP solutions. Guide highlights include: Why DLP The guide commences with an explanation of the role of the DLP. DLPs protect data from unwanted exposure by classification, determining its sensitivity level, and enforcing protective action. This is supposed to allow organizations to detect an...

The threat actors behind the BianLian ransomware have been observed exploiting security flaws in JetBrains TeamCity software to conduct their extortion-only attacks. According to a  new report  from GuidePoint Security, which responded to a recent intrusion, the incident "began with the exploitation of a TeamCity server which resulted in the deployment of a PowerShell implementation of BianLian's Go backdoor." BianLian  emerged  in June 2022, and has since pivoted exclusively to exfiltration-based extortion following the  release of a decryptor  in January 2023. The attack chain observed by the cybersecurity firm entails the exploitation of a vulnerable TeamCity instance using  CVE-2024-27198  or  CVE-2023-42793  to gain initial access to the environment, followed by creating new users in the build server and executing malicious commands for post-exploitation and lateral movement. It's currently not clear which of the two flaws wer...

Technical specifics and a proof-of-concept (PoC) exploit have been made available for a recently disclosed critical security flaw in Progress Software OpenEdge Authentication Gateway and AdminServer, which could be potentially exploited to bypass authentication protections. Tracked as  CVE-2024-1403 , the vulnerability has a maximum severity rating of 10.0 on the CVSS scoring system. It impacts OpenEdge versions 11.7.18 and earlier, 12.2.13 and earlier, and 12.8.0.  “When the OpenEdge Authentication Gateway (OEAG) is configured with an OpenEdge Domain that uses the OS local authentication provider to grant user-id and password logins on operating platforms supported by active releases of OpenEdge, a vulnerability in the authentication routines may lead to unauthorized access on attempted logins,” the company  said  in an advisory released late last month. “Similarly, when an AdminServer connection is made by OpenEdge Explorer (OEE) and OpenEdge Management (OEM),...

A financially motivated threat actor called  Magnet Goblin  is swiftly adopting one-day security vulnerabilities into its arsenal in order to opportunistically breach edge devices and public-facing services and deploy malware on compromised hosts. “Threat actor group Magnet Goblin’s hallmark is its ability to swiftly leverage newly disclosed vulnerabilities, particularly targeting public-facing servers and edge devices,” Check Point  said . “In some cases, the deployment of the exploits is within 1 day after a [proof-of-concept] is published, significantly increasing the threat level posed by this actor.” Attacks mounted by the adversary have leveraged unpatched Ivanti Connect Secure VPN, Magento, Qlik Sense, and possibly Apache ActiveMQ servers as an initial infection vector to gain unauthorized access. The group is said to be active since at least January 2022. A successful exploitation is followed by the deployment of a cross-platform remote access trojan (RAT) d...
