Raspberry Robin Malware Upgrades with Discord Spread and New Exploits

Raspberry Robin Malware Upgrades with Discord Spread and New Exploits

Feb 09, 2024 Malware / Dark Web
The operators of  Raspberry Robin  are now using two new one-day exploits to achieve local privilege escalation, even as the malware continues to be refined and improved to make it stealthier than before. This means that "Raspberry Robin has access to an exploit seller or its authors develop the exploits themselves in a short period of time," Check Point  said  in a report this week. Raspberry Robin (aka QNAP worm), first documented in 2021, is an  evasive malware family  that's known to act as one of the  top initial access facilitators  for other malicious payloads, including ransomware. Attributed to a threat actor named Storm-0856 (previously DEV-0856), it's propagated via several entry vectors, including infected USB drives, with Microsoft  describing  it as part of a "complex and interconnected malware ecosystem" with ties to other e-crime groups like  Evil Corp, Silence, and TA505 . Raspberry Robin's use of one-day exploits such as CVE-2020-

New Terrapin Flaw Could Let Attackers Downgrade SSH Protocol Security

Jan 01, 2024 Encryption / Network Security
Security researchers from Ruhr University Bochum have discovered a vulnerability in the Secure Shell ( SSH ) cryptographic network protocol that could allow an attacker to downgrade the connection's security by breaking the integrity of the secure channel. Called  Terrapin  ( CVE-2023-48795 , CVSS score: 5.9), the exploit has been described as the "first ever practically exploitable prefix truncation attack." "By carefully adjusting the sequence numbers during the handshake, an attacker can remove an arbitrary amount of messages sent by the client or server at the beginning of the secure channel without the client or server noticing it," researchers Fabian Bäumer, Marcus Brinkmann, and Jörg Schwenk  said . SSH is a  method  for securely sending commands to a computer over an unsecured network. It relies on cryptography to authenticate and encrypt connections between devices. This is accomplished by means of a handshake in which a client and server agree up

6 Steps to Accelerate Cybersecurity Incident Response

6 Steps to Accelerate Cybersecurity Incident Response

Nov 23, 2023 Incident Response / Endpoint Security
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 While these p

Alert: 'Effluence' Backdoor Persists Despite Patching Atlassian Confluence Servers

Nov 10, 2023 Cyber Attack / Threat Intelligence
Cybersecurity researchers have discovered a stealthy backdoor named  Effluence  that's deployed following the successful exploitation of a recently disclosed security flaw in Atlassian Confluence Data Center and Server. "The malware acts as a persistent backdoor and is not remediated by applying patches to Confluence," Aon's Stroz Friedberg Incident Response Services  said  in an analysis published earlier this week. "The backdoor provides capability for lateral movement to other network resources in addition to exfiltration of data from Confluence. Importantly, attackers can access the backdoor remotely without authenticating to Confluence." The attack chain documented by the cybersecurity entity entailed the exploitation of  CVE-2023-22515  (CVSS score: 10.0), a critical bug in Atlassian that could be abused to create unauthorized Confluence administrator accounts and access Confluence servers. Atlassian has since disclosed a second flaw known as  CV
The 4 Keys to Building Cloud Security Programs That Can Actually Shift Left

The 4 Keys to Building Cloud Security Programs That Can Actually Shift Left

Jul 27, 2023 Cloud Security / DevSecOps
As cloud applications are built, tested and updated, they wind their way through an ever-complex series of different tools and teams. Across hundreds or even thousands of technologies that make up the patchwork quilt of development and cloud environments, security processes are all too often applied in only the final phases of software development.  Placing security at the very end of the production pipeline puts both devs and security on the back foot. Developers want to build and ship secure apps; security teams want to support this process by strengthening application security. However, today's security processes are legacy approaches that once worked brilliantly for the tight constraints of on-prem production, but struggle in ever-shifting cloud environments. As a result, security is an afterthought, and any attempt to squeeze siloed security into agile SDLC can  swell the cost of patching by 600% . A new cloud security operating model is long overdue. Shift-left is an appro
