Microsoft has opened the lid on a large-scale phishing-as-a-service (PHaaS) operation that's involved in selling phishing kits and email templates as well as providing hosting and automated services at a low cost, thus enabling cyber actors to purchase phishing campaigns and deploy them with minimal efforts. "With over 100 available phishing templates that mimic known brands and services, the BulletProofLink operation is responsible for many of the phishing campaigns that impact enterprises today," Microsoft 365 Defender Threat Intelligence Team  said  in a Tuesday report. "BulletProofLink (also referred to as BulletProftLink or Anthrax by its operators in various websites, ads, and other promotional materials) is used by multiple attacker groups in either one-off or monthly subscription-based business models, creating a steady revenue stream for its operators." The tech giant said it uncovered the operation during its investigation of a credential phishing...

As many as 11 security vulnerabilities have been disclosed in Nagios network management systems, some of which could be chained to achieve pre-authenticated remote code execution with the highest privileges, as well as lead to credential theft and phishing attacks.  Industrial cybersecurity firm Claroty, which discovered the flaws, said flaws in tools such as Nagios make them an attractive target owing to their "oversight of core servers, devices, and other critical components in the enterprise network." The issues have since been fixed in updates released in August with Nagios XI 5.8.5 or above, Nagios XI Switch Wizard 2.5.7 or above, Nagios XI Docker Wizard 1.13 or above, and Nagios XI WatchGuard 1.4.8 or above. " SolarWinds  and  Kaseya  were likely targeted not only because of their large and influential customer bases, but also because of their respective technologies' access to enterprise networks, whether it was managing IT, operational technology (OT), or ...

One of the determining factors of how much damage a cyber-attack cause is how fast organizations can respond to it. Time to response is critical for security teams, and it is a major hurdle for leaner teams. To help improve this metric and enhance organizations' ability to respond to attacks quickly, many endpoint detection and response (EDR) and extended detection and response (XDR) vendors have started including some form of automation in their platforms to reduce the need for manual intervention. XDR provider Cynet claims that they go beyond existing solutions when it comes to security automation. More than automating individual components, the Cynet 360 platform ( see a live demo here ) offers automation across every phase of incident response – from detection through remediation. The company uses a variety of tools and techniques to keep organizations safe and quickly respond to any emerging threat. How Cynet removes the guesswork from Incident Response  Cynet fully auto...

The U.S. Treasury Department on Tuesday imposed sanctions on Russian cryptocurrency exchange Suex for helping facilitate and launder transactions from at least eight ransomware variants as part of the government's efforts to crack down on a surge in ransomware incidents and make it difficult for bad actors to profit from such attacks using digital currencies. "Virtual currency exchanges such as SUEX are critical to the profitability of ransomware attacks, which help fund additional cybercriminal activity," the department  said  in a press release. "Analysis of known SUEX transactions shows that over 40% of SUEX's known transaction history is associated with illicit actors. SUEX is being designated pursuant to  Executive Order 13694 , as amended, for providing material support to the threat posed by criminal ransomware actors." According to blockchain analytics firm  Chainalysis , SUEX is legally registered in the Czech Republic and operates out of office...

Over the last several years, there have been numerous high-profile security breaches. These breaches have underscored the fact that traditional cyber defenses have become woefully inadequate and that stronger defenses are needed. As such, many organizations have transitioned toward a zero trust security model. A zero trust security model is based on the idea that no IT resource should be trusted implicitly. Prior to the introduction of zero trust security, a user who authenticated into a network was trustworthy for the duration of their session, as was the user's device. In a zero trust model, a user is no longer considered to be trustworthy just because they entered a password at the beginning of their session. Instead, the user's identity is verified through multi-factor authentication, and the user may be prompted to re-authenticate if they attempt to access resources that are particularly sensitive or if the user attempts to do something out of the ordinary. How Complic...

Networking equipment company Netgear has released patches to remediate a high-severity remote code execution vulnerability affecting multiple routers that could be exploited by remote attackers to take control of an affected system. Traced as  CVE-2021-40847  (CVSS score: 8.1), the security weakness impacts the following models - R6400v2 (fixed in firmware version 1.0.4.120) R6700 (fixed in firmware version 1.0.2.26) R6700v3 (fixed in firmware version 1.0.4.120) R6900 (fixed in firmware version 1.0.2.26) R6900P (fixed in firmware version 3.3.142_HOTFIX) R7000 (fixed in firmware version 1.0.11.128) R7000P (fixed in firmware version 1.3.3.142_HOTFIX) R7850 (fixed in firmware version 1.0.5.76) R7900 (fixed in firmware version 1.0.4.46) R8000 (fixed in firmware version 1.0.4.76) RS400 (fixed in firmware version 1.5.1.80) According to GRIMM security researcher Adam Nichols, the vulnerability resides within Circle , a third-party component included in the firmware t...

VMware on Tuesday published a new bulletin warning of as many as 19 vulnerabilities in vCenter Server and Cloud Foundation appliances that a remote attacker could exploit to take control of an affected system. The most urgent among them is an arbitrary file upload vulnerability in the Analytics service (CVE-2021-22005) that impacts vCenter Server 6.7 and 7.0 deployments. "A malicious actor with network access to port 443 on vCenter Server may exploit this issue to execute code on vCenter Server by uploading a specially crafted file," the company  noted ,  adding  "this vulnerability can be used by anyone who can reach vCenter Server over the network to gain access, regardless of the configuration settings of vCenter Server." Although VMware has published  workarounds  for the flaw, the company cautioned that they are "meant to be a temporary solution until updates […] can be deployed." The complete list of flaws patched by the virtualization services ...
