Russian Hackers Linked to 'Largest Ever Cyber Attack' on Danish Critical Infrastructure

Russian Hackers Linked to 'Largest Ever Cyber Attack' on Danish Critical Infrastructure

Nov 16, 2023 Cyber Warfare / Threat Intelligence
Russian threat actors have been possibly linked to what's been described as the "largest cyber attack against Danish critical infrastructure," in which 22 companies associated with the operation of the country's energy sector were targeted in May 2023.  "22 simultaneous, successful cyberattacks against Danish critical infrastructure are not commonplace," Denmark's SektorCERT  said  [PDF]. "The attackers knew in advance who they were going to target and got it right every time. Not once did a shot miss the target." The agency said it found evidence connecting one or more attacks to Russia's GRU military intelligence agency, which is also tracked under the name  Sandworm  and has a track record of orchestrating disruptive cyber assaults on industrial control systems. This assessment is based on artifacts communicating with IP addresses that have been traced to the hacking crew. The unprecedented and coordinated cyber attacks took place on
New PoC Exploit for Apache ActiveMQ Flaw Could Let Attackers Fly Under the Radar

New PoC Exploit for Apache ActiveMQ Flaw Could Let Attackers Fly Under the Radar

Nov 15, 2023 Ransomware / Vulnerability
Cybersecurity researchers have demonstrated a new technique that exploits a critical security flaw in Apache ActiveMQ to achieve arbitrary code execution in memory. Tracked as  CVE-2023-46604  (CVSS score: 10.0), the vulnerability is a remote code execution bug that could permit a threat actor to run arbitrary shell commands. It was patched by Apache in ActiveMQ versions 5.15.16, 5.16.7, 5.17.6, or 5.18.3 released late last month. The vulnerability has since  come under   active exploitation  by ransomware outfits to deploy ransomware such as HelloKitty and a strain that shares similarities with TellYouThePass as well as a remote access trojan called SparkRAT. According to  new findings  from VulnCheck, threat actors weaponizing the flaw are  relying  on a public proof-of-concept ( PoC ) exploit originally disclosed on October 25, 2023. The attacks have been found to use  ClassPathXmlApplicationContext , a class that's part of the Spring framework and available within Active

Hands-on Review: Cynomi AI-powered vCISO Platform

Apr 10, 2024vCISO / Risk Assessment
The need for vCISO services is growing. SMBs and SMEs are dealing with more third-party risks, tightening regulatory demands and stringent cyber insurance requirements than ever before. However, they often lack the resources and expertise to hire an in-house security executive team. By outsourcing security and compliance leadership to a vCISO, these organizations can more easily obtain cybersecurity expertise specialized for their industry and strengthen their cybersecurity posture. MSPs and MSSPs looking to meet this growing vCISO demand are often faced with the same challenge. The demand for cybersecurity talent far exceeds the supply. This has led to a competitive market where the costs of hiring and retaining skilled professionals can be prohibitive for MSSPs/MSPs as well. The need to maintain expertise of both security and compliance further exacerbates this challenge. Cynomi, the first AI-driven vCISO platform , can help. Cynomi enables you - MSPs, MSSPs and consulting firms

Nov 14, 2023 Cyber Attack / Vulnerability
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has given a November 17, 2023, deadline for federal agencies and organizations to apply mitigations to secure against a number of security flaws in Juniper Junos OS that came to light in August. The agency on Monday  added  five vulnerabilities to the Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation - CVE-2023-36844  (CVSS score: 5.3) - Juniper Junos OS EX Series PHP External Variable Modification Vulnerability CVE-2023-36845  (CVSS score: 5.3) - Juniper Junos OS EX Series and SRX Series PHP External Variable Modification Vulnerability CVE-2023-36846  (CVSS score: 5.3) - Juniper Junos OS SRX Series Missing Authentication for Critical Function Vulnerability CVE-2023-36847  (CVSS score: 5.3) - Juniper Junos OS EX Series Missing Authentication for Critical Function Vulnerability CVE-2023-36851  (CVSS score: 5.3) - Juniper Junos OS SRX Series Missing Authentication for Critical

New Ransomware Group Emerges with Hive's Source Code and Infrastructure

New Ransomware Group Emerges with Hive's Source Code and Infrastructure

Nov 13, 2023 Cyber Threat / Malware
The threat actors behind a new ransomware group called  Hunters International  have acquired the source code and infrastructure from the now-dismantled Hive operation to kick-start its own efforts in the threat landscape. "It appears that the leadership of the Hive group made the strategic decision to cease their operations and transfer their remaining assets to another group, Hunters International," Martin Zugec, technical solutions director at Bitdefender,  said  in a report published last week. Hive, once a prolific ransomware-as-a-service (RaaS) operation, was  taken down  as part of a coordinated law enforcement operation in January 2023. While it's common for ransomware actors to regroup, rebrand, or disband their activities following such seizures, what can also happen is that the core developers can pass on the source code and other infrastructure in their possession to another threat actor. Reports about Hunters International as a possible Hive rebrand  sur
Experts Expose Farnetwork's Ransomware-as-a-Service Business Model

Experts Expose Farnetwork's Ransomware-as-a-Service Business Model

Nov 08, 2023 Cyber Threat / Endpoint Security
Cybersecurity researchers have unmasked a prolific threat actor known as farnetwork, who has been linked to five different ransomware-as-a-service (RaaS) programs over the past four years in various capacities. Singapore-headquartered Group-IB, which attempted to infiltrate a private RaaS program that uses the  Nokoyawa   ransomware  strain, said it underwent a "job interview" process with the threat actor, learning several valuable insights into their background and role within those RaaS programs. "Throughout the threat actor's cybercriminal career, which began in 2019, farnetwork has been involved in several connected ransomware projects, including JSWORM, Nefilim, Karma, and Nemty, as part of which they helped develop ransomware and manage the RaaS programs before launching their own RaaS program based on Nokoyawa ransomware," Nikolay Kichatov, threat intelligence analyst at Group-IB,  said . The latest disclosure comes nearly six months after the cyber
