Legion Malware Upgraded to Target SSH Servers and AWS Credentials
May 24, 2023
Server Security / Malware
An updated version of the commodity malware called Legion comes with expanded features to compromise SSH servers and Amazon Web Services (AWS) credentials associated with DynamoDB and CloudWatch. "This recent update demonstrates a widening of scope, with new capabilities such the ability to compromise SSH servers and retrieve additional AWS-specific credentials from Laravel web applications," Cado Labs researcher Matt Muir said in a report shared with The Hacker News. "It's clear that the developer's targeting of cloud services is advancing with each iteration." Legion, a Python-based hack tool, was first documented last month by the cloud security firm, detailing its ability to breach vulnerable SMTP servers in order to harvest credentials. It's also known to exploit web servers running content management systems (CMS), leverage Telegram as a data exfiltration point, and send spam SMS messages to a list of dynamically-generated U.S. mobile num
New ShellBot DDoS Malware Variants Targeting Poorly Managed Linux Servers
Mar 21, 2023
Linux / Server Security
Poorly managed Linux SSH servers are being targeted as part of a new campaign that deploys different variants of a malware called ShellBot. "ShellBot, also known as PerlBot , is a DDoS Bot malware developed in Perl and characteristically uses IRC protocol to communicate with the C&C server," AhnLab Security Emergency response Center (ASEC) said in a report. ShellBot is installed on servers that have weak credentials, but only after threat actors make use of scanner malware to identify systems that have SSH port 22 open. A list of known SSH credentials is used to initiate a dictionary attack to breach the server and deploy the payload, after which it leverages the Internet Relay Chat ( IRC ) protocol to communicate with a remote server. This encompasses the ability to receive commands that allows ShellBot to carry out DDoS attacks and exfiltrate harvested information. ASEC said it identified three different ShellBot versions – LiGhT's Modded perlbot v2, DDoS

AI Solutions Are the New Shadow IT
Nov 22, 2023
AI Security / SaaS Security
Ambitious Employees Tout New AI Tools, Ignore Serious SaaS Security Risks Like the SaaS shadow IT of the past, AI is placing CISOs and cybersecurity teams in a tough but familiar spot. Employees are covertly using AI with little regard for established IT and cybersecurity review procedures. Considering ChatGPT's meteoric rise to 100 million users within 60 days of launch , especially with little sales and marketing fanfare, employee-driven demand for AI tools will only escalate. As new studies show some workers boost productivity by 40% using generative AI , the pressure for CISOs and their teams to fast-track AI adoption — and turn a blind eye to unsanctioned AI tool usage — is intensifying. But succumbing to these pressures can introduce serious SaaS data leakage and breach risks, particularly as employees flock to AI tools developed by small businesses, solopreneurs, and indie developers.

North Korean Hackers Spreading Trojanized Versions of PuTTY Client Application
Sep 16, 2022
A threat with a North Korea nexus has been found leveraging a "novel spear phish methodology" that involves making use of trojanized versions of the PuTTY SSH and Telnet client. Google-owned threat intelligence firm Mandiant attributed the new campaign to an emerging threat cluster it tracks under the name UNC4034 . "UNC4034 established communication with the victim over WhatsApp and lured them to download a malicious ISO package regarding a fake job offering that led to the deployment of the AIRDRY.V2 backdoor through a trojanized instance of the PuTTY utility," Mandiant researchers said . The utilization of fabricated job lures as a pathway for malware distribution is an oft-used tactic by North Korean state-sponsored actors, including the Lazarus Group, as part of an enduring campaign called Operation Dream Job . The entry point of the attack is an ISO file that masquerades as an Amazon Assessment as part of a potential job opportunity at the tech giant.
New Linux Malware Framework Lets Attackers Install Rootkit on Targeted Systems
Jul 21, 2022
A never-before-seen Linux malware has been dubbed a "Swiss Army Knife" for its modular architecture and its capability to install rootkits. This previously undetected Linux threat, called Lightning Framework by Intezer, is equipped with a plethora of features, making it one of the most intricate frameworks developed for targeting Linux systems. "The framework has both passive and active capabilities for communication with the threat actor, including opening up SSH on an infected machine, and a polymorphic malleable command and control configuration," Intezer researcher Ryan Robinson said in a new report published today. Central to the malware is a downloader ("kbioset") and a core ("kkdmflush") module, the former of which is engineered to retrieve at least seven different plugins from a remote server that are subsequently invoked by the core component. In addition, the downloader is also responsible for establishing the persistence of t
