SystemBC | Breaking Cybersecurity News | The Hacker News

Ukrainian entities based in Finland have been targeted as part of a malicious campaign distributing a commercial remote access trojan known as Remcos RAT using a malware loader called IDAT Loader. The attack has been attributed to a threat actor tracked by the Computer Emergency Response Team of Ukraine (CERT-UA) under the moniker UAC-0184. "The attack, as part of the IDAT Loader, used steganography as a technique," Morphisec researcher Michael Dereviashkin said in a report shared with The Hacker News. "While steganographic, or 'Stego' techniques are well-known, it is important to understand their roles in defense evasion, to better understand how to defend against such tactics." IDAT Loader , which overlaps with another loader family called Hijack Loader, has been used to serve additional payloads like DanaBot, SystemBC, and RedLine Stealer in recent months. It has also been used by a threat actor tracked as TA544 to distribute Remcos RAT and SystemBC...

Cybersecurity researchers have shed light on the command-and-control (C2) server workings of a known malware family called  SystemBC . "SystemBC can be purchased on underground marketplaces and is supplied in an archive containing the implant, a command-and-control (C2) server, and a web administration portal written in PHP," Kroll  said  in an analysis published last week. The risk and financial advisory solutions provider said it has witnessed an increase in the use of malware throughout Q2 and Q3 2023. SystemBC,  first observed  in the wild in 2018, allows threat actors to remote control a compromised host and deliver additional payloads, including trojans, Cobalt Strike, and ransomware. It also features support for launching ancillary modules on the fly to expand on its core functionality. A standout aspect of the malware revolves around its use of SOCKS5 proxies to mask network traffic to and from C2 infrastructure, acting as a persistent access mecha...

The Gootkit malware is prominently going after healthcare and finance organizations in the U.S., U.K., and Australia, according to new findings from Cybereason. The cybersecurity firm said it investigated a Gootkit incident in December 2022 that adopted a new method of deployment, with the actors abusing the foothold to deliver  Cobalt Strike  and  SystemBC  for post-exploitation. "The threat actor displayed fast-moving behaviors, quickly heading to control the network it infected, and getting elevated privileges in less than four hours," Cybereason  said  in an analysis published February 8, 2023. Gootkit, also called Gootloader, is exclusively attributed to a threat actor tracked by Mandiant as UNC2565. Starting its life in 2014 as a banking trojan, the malware has since morphed into a loader capable of delivering next-stage payloads. The shift in tactics was  first uncovered  by Sophos in March 2021. Gootloader takes the form of heavily-o...

Not every security vulnerability is high risk on its own - but in the hands of an advanced attacker, even small weaknesses can escalate into major breaches. These five real vulnerabilities, uncovered by Intruder's bug-hunting team, reveal how attackers turn overlooked flaws into serious security incidents. 1. Stealing AWS Credentials with a Redirect Server-Side Request Forgery (SSRF) is a common vulnerability that can have a significant impact, especially in cloud-hosted applications. If a web application fetches resources from user-supplied URLs, care should be taken to ensure attackers can't manipulate requests to access unintended resources. While assessing a home-moving app running in AWS, our team tested common SSRF bypass techniques. The attack chain was as follows: the app sent a webhook request to the attacker's web server, which responded with a 302 redirect to AWS's metadata service. The app followed the redirect and logged the response, which exposed sensitive metadat...

Cybercriminals are increasingly outsourcing the task of deploying ransomware to affiliates using commodity malware and attack tools, according to new research. In a new analysis published by Sophos today and shared with The Hacker News, recent deployments of  Ryuk  and  Egregor  ransomware have involved the use of  SystemBC  backdoor to laterally move across the network and fetch additional payloads for further exploitation. Affiliates are typically threat actors responsible for gaining an initial foothold in a target network. "SystemBC is a regular part of recent ransomware attackers' toolkits," said Sophos senior threat researcher and former Ars Technica national security editor Sean Gallagher. "The backdoor can be used in combination with other scripts and malware to perform discovery, exfiltration and lateral movement in an automated way across multiple targets. These SystemBC capabilities were originally intended for mass exploitation, but they h...
