Cybersecurity Agencies Sound Alarm on Rising TrueBot Malware Attacks

Cybersecurity Agencies Sound Alarm on Rising TrueBot Malware Attacks
Jul 07, 2023 Cyber Attack / Malware
Cybersecurity agencies have warned about the emergence of new variants of the TrueBot malware. This enhanced threat is now targeting companies in the U.S. and Canada with the intention of extracting confidential data from infiltrated systems. These sophisticated attacks exploit a critical vulnerability ( CVE-2022-31199 ) in the widely used Netwrix Auditor server and its associated agents. This vulnerability enables unauthorized attackers to execute malicious code with the SYSTEM user's privileges, granting them unrestricted access to compromised systems. The TrueBot malware , linked with cybercriminal collectives Silence and FIN11, is deployed to siphon off data and disseminate ransomware, jeopardising the safety of numerous infiltrated networks. The cybercriminals gain their initial foothold by exploiting the cited vulnerability, then proceed to install TrueBot. Once they have breached the networks, they install the FlawedGrace Remote Access Trojan (RAT) to escalate their p

Alarming Surge in TrueBot Activity Revealed with New Delivery Vectors

Alarming Surge in TrueBot Activity Revealed with New Delivery Vectors
Jun 05, 2023 Malware / Cyber Threat
A surge in TrueBot activity was observed in May 2023, cybersecurity researchers disclosed. "TrueBot is a downloader trojan botnet that uses command and control servers to collect information on compromised systems and uses that compromised system as a launching point for further attacks," VMware's Fae Carlisle  said . Active since at least 2017, TrueBot is linked to a group known as Silence that's believed to share overlaps with the notorious Russian cybercrime actor known as  Evil Corp . Recent  TrueBot infections  have leveraged a critical flaw in Netwrix Auditor ( CVE-2022-31199 , CVSS score: 9.8) as well as  Raspberry Robin  as delivery vectors. The attack chain documented by VMware, on the other hand, starts off with a drive-by-download of an executable named " update.exe " from Google Chrome, suggesting that users are lured into downloading the malware under the pretext of a software update. Once run, update.exe establishes connections with a k

New Analysis Reveals Raspberry Robin Can be Repurposed by Other Threat Actors

New Analysis Reveals Raspberry Robin Can be Repurposed by Other Threat Actors
Jan 11, 2023 Cyber Threat / Malware
A new analysis of Raspberry Robin's attack infrastructure has  revealed  that it's possible for other threat actors to repurpose the infections for their own malicious activities, making it an even more potent threat. Raspberry Robin (aka QNAP worm), attributed to a threat actor dubbed DEV-0856, is a malware that has  increasingly   come under the radar  for being used in attacks aimed at finance, government, insurance, and telecom entities. Given its use by multiple threat actors to drop a wide range of payloads such as SocGholish , Bumblebee ,  TrueBot ,  IcedID , and  LockBit  ransomware, it's believed to be a pay-per-install (PPI) botnet capable of serving next-stage malware. Raspberry Robin, notably, employs infected USB drives as a propagation mechanism and leverages breached QNAP network-attached storage (NAS) devices as first-level command-and-control (C2). Cybersecurity firm SEKOIA said it was able to identify at least eight virtual private servers (VPSs) hos

SHQ Response Platform and Risk Centre to Enable Management and Analysts Alike

SHQ Response Platform and Risk Centre to Enable Management and Analysts Alike
May 13, 2024Threat Detection / SoC / SIEM
In the last decade, there has been a growing disconnect between front-line analysts and senior management in IT and Cybersecurity. Well-documented challenges facing modern analysts revolve around a high volume of alerts, false positives, poor visibility of technical environments, and analysts spending too much time on manual tasks. The Impact of Alert Fatigue and False Positives  Analysts are overwhelmed with alerts. The knock-on effect of this is that fatigued analysts are at risk of missing key details in incidents, and often conduct time-consuming triaging tasks manually only to end up copying and pasting a generic closing comment into a false positive alert.  It is likely that there will always be false positives. And many would argue that a false positive is better than a false negative. But for proactive actions to be made, we must move closer to the heart of an incident. That requires diving into how analysts conduct the triage and investigation process. SHQ Response Platfo
