Preventing Insider Threats in Your Active Directory

Preventing Insider Threats in Your Active Directory

Mar 22, 2023 Password Security / Active Directory
Active Directory (AD) is a powerful authentication and directory service used by organizations worldwide. With this ubiquity and power comes the potential for abuse. Insider threats offer some of the most potentials for destruction. Many internal users have over-provisioned access and visibility into the internal network. Insiders' level of access and trust in a network leads to unique vulnerabilities. Network security often focuses on keeping a threat actor out, not on existing users' security and potential vulnerabilities. Staying on top of potential threats means protecting against inside and outside threats. Active Directory Vulnerabilities From the outside, a properly configured AD domain offers a secure authentication and authorization solution. But with complex social engineering and phishing email attacks, an existing AD user can become compromised. Once inside, threat actors have many options to attack Active Directory.

Rogue NuGet Packages Infect .NET Developers with Crypto-Stealing Malware

Rogue NuGet Packages Infect .NET Developers with Crypto-Stealing Malware

Mar 22, 2023 DevOpsSec / Malware
The  NuGet  repository is the target of a new "sophisticated and highly-malicious attack" aiming to infect .NET developer systems with cryptocurrency stealer malware. The 13 rogue packages, which were downloaded more than 160,000 times over the past month, have since been taken down. "The packages contained a PowerShell script that would execute upon installation and trigger a download of a 'second stage' payload, which could be remotely executed," JFrog researchers Natan Nehorai and Brian Moussalli  said . While NuGet packages have been in the past found to  contain vulnerabilities  and be abused to  propagate phishing links , the development marks the first-ever discovery of packages with malicious code. Three of the most downloaded packages – Coinbase.Core, Anarchy.Wrapper.Net, and DiscordRichPresence.API – alone accounted for 166,000 downloads, although it's also possible that the threat actors artificially inflated the download counts using bo

Navigating the Threat Landscape: Understanding Exposure Management, Pentesting, Red Teaming and RBVM

Apr 29, 2024Exposure Management / Attack Surface
It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

NAPLISTENER: New Malware in REF2924 Group's Arsenal for Bypassing Detection

Mar 22, 2023 Network Security / Cyber Threat
The threat group tracked as  REF2924  has been observed deploying previously unseen malware in its attacks aimed at entities in South and Southeast Asia. The malware, dubbed  NAPLISTENER  by Elastic Security Labs, is an HTTP listener programmed in C# and is designed to evade "network-based forms of detection." REF2924  is the moniker assigned to an activity cluster linked to attacks against an entity in Afghanistan as well as the Foreign Affairs Office of an ASEAN member in 2022. The threat actor's modus operandi suggests overlaps with another hacking group dubbed  ChamelGang , which was documented by Russian cybersecurity company Positive Technologies in October 2021. Attacks orchestrated by the group are said to have exploited internet-exposed Microsoft Exchange servers to  deploy backdoors  such as DOORME, SIESTAGRAPH, and ShadowPad. DOORME, an Internet Information Services ( IIS ) backdoor module, provides remote access to a contested network and executes addit

BreachForums Administrator Baphomet Shuts Down Infamous Hacking Forum

BreachForums Administrator Baphomet Shuts Down Infamous Hacking Forum

Mar 22, 2023 Cyber Crime / Hacking
In a sudden turn of events, Baphomet, the current administrator of BreachForums, said in an update on March 21, 2023, that the hacking forum has been officially taken down but emphasized that "it's not the end." "You are allowed to hate me, and disagree with my decision but I promise what is to come will be better for us all," Baphomet noted in a message posted on the BreachForums Telegram channel. The  shutdown  is suspected to have been prompted by suspicions that law enforcement may have obtained access to the site's configurations, source code, and information about the forum's users. The development follows the  arrest of its administrator  Conor Brian Fitzpatrick (aka "pompompurin"), who has been charged with a single count of conspiracy to commit access device fraud. Over the past few months, BreachForums filled the void left by RaidForums last year, becoming a lucrative destination to purchase and sell stolen databases from variou
New 'Bad Magic' Cyber Threat Disrupts Ukraine's Key Sectors Amid War

New 'Bad Magic' Cyber Threat Disrupts Ukraine's Key Sectors Amid War

Mar 21, 2023 Cyber War / Cyber Threat
Amid the  ongoing war  between Russia and Ukraine, government, agriculture, and transportation organizations located in Donetsk, Lugansk, and Crimea have been attacked as part of an active campaign that drops a previously unseen, modular framework dubbed  CommonMagic . "Although the initial vector of compromise is unclear, the details of the next stage imply the use of spear phishing or similar methods," Kaspersky  said  in a new report. The Russian cybersecurity company, which detected the attacks in October 2022, is tracking the activity cluster under the name "Bad Magic." Attack chains entail the use of booby-trapped URLS pointing to a ZIP archive hosted on a malicious web server. The file, when opened, contains a decoy document and a malicious LNK file that culminates in the deployment of a backdoor named PowerMagic. Written in PowerShell, PowerMagic establishes contact with a remote server and executes arbitrary commands, the results of which are exfiltra

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

H0lyGh0st, Magecart, and a slew of state-sponsored hacker groups are diversifying their tactics and shifting their focus to… You. That is, if you're in charge of cybersecurity for a small-to-midsize enterprise (SME). Why? Bad actors know that SMEs typically have a smaller security budget, less infosec manpower, and possibly weak or missing security controls to protect their data and infrastructure. So, how can you prepare for the imminent onslaught from new and emerging threat groups?  You need a plan. Start with the NIST Cyber Security Framework The good news is you don't have to create your security strategy from scratch. The National Institute of Standards and Technology Cyber Security Framework (NIST CSF) is one of the most respected and widely used standards in the world. While originally designed for critical infrastructure industries, the NIST CSF is flexible enough for organizations of all sizes, sectors, and maturities to use in large part because the framewor
From Ransomware to Cyber Espionage: 55 Zero-Day Vulnerabilities Weaponized in 2022

From Ransomware to Cyber Espionage: 55 Zero-Day Vulnerabilities Weaponized in 2022

Mar 21, 2023 Cyber Threat Intel / Vulnerability
As many as 55 zero-day vulnerabilities were exploited in the wild in 2022, with most of the flaws discovered in software from Microsoft, Google, and Apple. While this figure represents a decrease from the year before, when a staggering 81 zero-days were weaponized, it still represents a significant uptick in recent years of threat actors leveraging unknown security flaws to their advantage. The  findings  come from threat intelligence firm Mandiant, which noted that desktop operating systems (19), web browsers (11), IT and network management products (10), and mobile operating systems (six) accounted for the most exploited product types. Of the 55 zero-day bugs, 13 are estimated to have been abused by cyber espionage groups, with four others exploited by financially motivated threat actors for ransomware-related operations. Commercial spyware vendors were linked to the exploitation of three zero-days. Among state-sponsored groups, those attributed to China have emerged as the most

Hackers Steal Over $1.6 Million in Crypto from General Bytes Bitcoin ATMs Using Zero-Day Flaw

Mar 21, 2023 Cryptocurrency / Hacking
Bitcoin ATM maker General Bytes disclosed that unidentified threat actors stole cryptocurrency from hot wallets by exploiting a zero-day security flaw in its software. "The attacker was able to upload his own java application remotely via the master service interface used by terminals to upload videos and run it using 'batm' user privileges," the company  said  in an advisory published over the weekend. "The attacker scanned the Digital Ocean cloud hosting IP address space and identified running CAS services on ports 7741, including the General Bytes Cloud service and other GB ATM operators running their servers on Digital Ocean," it further added. The company said that the server to which the malicious Java application was uploaded was by default configured to start applications present in the deployment folder ("/batm/app/admin/standalone/deployments/"). In doing so, the attack allowed the threat actor to access the database; read and decry
