Medieval castles stood as impregnable fortresses for centuries, thanks to their meticulous design. Fast forward to the digital age, and this medieval wisdom still echoes in cybersecurity. Like castles with strategic layouts to withstand attacks, the Defense-in-Depth strategy is the modern counterpart — a multi-layered approach with strategic redundancy and a blend of passive and active security controls.  However, the evolving cyber threat landscape can challenge even the most fortified defenses. Despite the widespread adoption of the Defense-in-Depth strategy, cyber threats persist. Fortunately, the Defense-in-Depth strategy can be augmented using Breach and Attack Simulation (BAS), an automated tool that assesses and improves every security control in each layer. Defense-in-Depth: False Sense of Security with Layers Also known as multi-layered defense, the defense-in-depth strategy has been widely adopted by organizations since the early 2000s. It's based on the assumption that a

A decryptor for the Tortilla variant of the Babuk ransomware has been  released  by Cisco Talos, allowing victims targeted by the malware to regain access to their files. The cybersecurity firm said the threat intelligence it shared with Dutch law enforcement authorities made it possible to arrest the threat actor behind the operations. The encryption key has also been shared with Avast, which had previously  released a decryptor  for Babuk ransomware after its  source code was leaked  in September 2021. The updated decryptor can be accessed  here  [EXE file]. "A single private key is used for all victims of the Tortilla threat actor," Avast  noted . "This makes the update to the decryptor especially useful, as all victims of the campaign can use it to decrypt their files." The Tortilla campaign was  first disclosed  by Talos in November 2021, with the attacks leveraging  ProxyShell flaws in Microsoft Exchange servers  to drop the ransomware within victim environments. Tortilla

Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or

Ransomware attacks  have become a significant and pervasive threat in the ever-evolving realm of cybersecurity. Among the various iterations of ransomware, one trend that has gained prominence is Ransomware-as-a-Service (RaaS). This alarming development has transformed the cybercrime landscape, enabling individuals with limited technical expertise to carry out devastating attacks. Traditional and double extortion ransomware attacks Traditionally, ransomware refers to a type of malware that encrypts the victim's files, effectively blocking access to data and applications until a ransom is paid to the attacker. However, more contemporary attackers often employ an additional strategy. The bad actors create copies of the compromised data and leverage the threat of publishing sensitive information online unless their demands for ransom are met. This dual approach adds an extra layer of complexity and potential harm to the victims. A new model for ransomware RaaS is the latest busin

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added three security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog based on evidence of active exploitation in the wild. The  vulnerabilities  are as follows - CVE-2023-36584  (CVSS score: 5.4) - Microsoft Windows Mark-of-the-Web (MotW) Security Feature Bypass Vulnerability CVE-2023-1671  (CVSS score: 9.8) - Sophos Web Appliance Command Injection Vulnerability CVE-2020-2551  (CVSS score: 9.8) - Oracle Fusion Middleware Unspecified Vulnerability CVE-2023-1671 relates to a critical  pre-auth command injection vulnerability  that allows for the execution of arbitrary code. CVE-2020-2551 is a  flaw  in the WLS Core Components that allows an unauthenticated attacker with network access to compromise the WebLogic Server. There are currently no public reports documenting in-the-wild attacks leveraging CVE-2023-1671, but Cybernews disclosed in July 2023 that it had identified a subdomain of t

Russian threat actors have been possibly linked to what's been described as the "largest cyber attack against Danish critical infrastructure," in which 22 companies associated with the operation of the country's energy sector were targeted in May 2023.  "22 simultaneous, successful cyberattacks against Danish critical infrastructure are not commonplace," Denmark's SektorCERT  said  [PDF]. "The attackers knew in advance who they were going to target and got it right every time. Not once did a shot miss the target." The agency said it found evidence connecting one or more attacks to Russia's GRU military intelligence agency, which is also tracked under the name  Sandworm  and has a track record of orchestrating disruptive cyber assaults on industrial control systems. This assessment is based on artifacts communicating with IP addresses that have been traced to the hacking crew. The unprecedented and coordinated cyber attacks took place on

Microsoft on Wednesday said that a user containment feature in Microsoft Defender for Endpoint helped thwart a "large-scale remote encryption attempt" made by  Akira ransomware actors  targeting an unknown industrial organization in early June 2023. The tech giant's threat intelligence team is tracking the operator as Storm-1567. The attack leveraged devices that were not onboarded to Microsoft Defender for Endpoint as a defense evasion tactic, while also conducting a series of reconnaissance and lateral movement activities prior to encrypting the devices using a compromised user account. But the new  automatic attack disruption capability  meant that the breached accounts are prevented from "accessing endpoints and other resources in the network, limiting attackers' ability to move laterally regardless of the account's Active Directory state or privilege level." In other words, the idea is to cut off all inbound and outbound communication and proh

The Computer Emergency Response Team of Ukraine (CERT-UA) has warned of cyber attacks targeting state bodies in the country as part of an espionage campaign. The  intrusion set , attributed to a threat actor tracked by the authority as UAC-0063 since 2021, leverages phishing lures to deploy a variety of malicious tools on infected systems. The origins of the hacking crew are presently unknown. In the attack chain described by the agency, the emails targeted an unspecified ministry and purported to be from the Embassy of Tajikistan in Ukraine. It's suspected that the messages were sent from a previously compromised mailbox. The emails come attached with a Microsoft Word document that, upon enabling macros, launches an encoded VBScript called HATVIBE, which is then used to drop additional malware. This includes a keylogger (LOGPIE), a Python-based backdoor capable of running commands sent from a remote server (CHERRYSPY), and a tool focused on exfiltrating files with specific e

The US government's $6 Billion firewall is nothing but a big blunder. Dubbed EINSTEIN , the nationwide firewall run by the US Department of Homeland Security (DHS) is not as smart as its name suggests. An audit conducted by the United States Government Accountability Office (GAO) has claimed that the firewall used by US government agencies is failing to fully meet its objectives and leaving the agencies open to zero-day attacks. EINSTEIN, which is officially known as the US' National Cybersecurity Protection System (NCPS) and has cost $5.7 Billion to develop, detects only 6 percent of today's most common security vulnerabilities and failed to detect the rest 94 percent. How bad is EINSTEIN Firewall in reality? In a series of tests conducted last year, Einstein only detected 29 out of 489 vulnerabilities across Flash, Office, Java, IE and Acrobat disclosed via CVE reports published in 2014, according to a report [ PDF ] released by the GAO late las

As organizations expand their IT infrastructure to match their evolving business models and meet changing regulatory requirements, they often find that their networks have become extremely complex and challenging to manage. A primary concern for many IT teams is detecting threats in the mountain of event data being generated every day. Even a relatively small network can generate hundreds or thousands of events per second, with every system, application, and service generating events. The sheer volume of data makes it virtually impossible to identify manually and link those few events that indicate a successful network breach and system compromise, before the exfiltration of data. The AlienVault Unified Security Management (USM) platform is a solution to help IT teams with limited resources overcome the challenge of detecting threats in their network. USM platform accelerates and simplifies your ability to detect, prioritize, and respond to the most critical

Simply put, threat intelligence is knowledge that helps you identify security threats and make informed decisions. Threat intelligence can help you solve the following problems: How do I keep up to date on the overwhelming amount of information on security threats…including bad actors, methods, vulnerabilities, targets, etc.? How do I get more proactive about future security threats? How do I inform my leaders about the dangers and repercussions of specific security threats? Threat Intelligence: What is it? Threat intelligence has received a lot of attention lately. While there are many different definitions, here are a few that get quoted often: Threat intelligence is evidence-based knowledge, including context, mechanisms, indicators, implications and actionable advice, about an existing or emerging menace or hazard to assets that can be used to inform decisions regarding the subject's response to that menace or hazard. – Gartner   The set of data collected, assessed and app
