In the wake of high-profile attacks on UK retailers Marks & Spencer and Co-op, Scattered Spider has been all over the media, with coverage spilling over into the mainstream news due to the severity of the disruption caused — currently looking like hundreds of millions in lost profits for M&S alone.  This coverage is extremely valuable for the cybersecurity community as it raises awareness of the battles that security teams are fighting every day. But it's also created a lot of noise that can make it tricky to understand the big picture.  The headline story from the recent campaign against UK retailers is the use of help desk scams. This typically involves the attacker calling up a company's help desk with some level of information — at minimum, PII that allows them to impersonate their victim, and sometimes a password, leaning heavily on their native English-speaking abilities to trick the help desk operator into giving them access to a user account.  Help Des...

The official site for RVTools has been hacked to serve a compromised installer for the popular VMware environment reporting utility. "Robware.net and RVTools.com are currently offline.

In 2024, ransomware attacks targeting VMware ESXi servers reached alarming levels, with the average ransom demand skyrocketing to $5 million. With approximately 8,000 ESXi hosts exposed directly to the internet (according to Shodan), the operational and business impact of these attacks is profound. Most of the Ransomware strands that are attacking ESXi servers nowadays, are variants of the infamous Babuk ransomware, adapted to avoid detection of security tools. Moreover, accessibility is becoming more widespread, as attackers monetize their entry points by selling Initial Access to other threat actors, including ransomware groups. As organizations are dealing with compounded threats on an ever-expanding front: new vulnerabilities, new entry points, monetized cyber-crime networks, and more, there is ever-growing urgency for enhanced security measures and vigilance. The architecture of ESXi Understanding how an attacker can gain control of the ESXi host begins with understanding the ...

Cybersecurity researchers have shed light on a Linux variant of a relatively new ransomware strain called Helldown, suggesting that the threat actors are broadening their attack focus. "Helldown deploys Windows ransomware derived from the LockBit 3.0 code," Sekoia said in a report shared with The Hacker News. "Given the recent development of ransomware targeting ESX, it appears that the group could be evolving its current operations to target virtualized infrastructures via VMware." Helldown was first publicly documented by Halcyon in mid-August 2024, describing it as an "aggressive ransomware group" that infiltrates target networks by exploiting security vulnerabilities. Some of the prominent sectors targeted by the cybercrime group include IT services, telecommunications, manufacturing, and healthcare. Like other ransomware crews, Helldown is known for leveraging data leak sites to pressure victims into paying ransoms by threatening to publish s...

Cybersecurity researchers have unpacked the inner workings of a new ransomware variant called Cicada3301 that shares similarities with the now-defunct BlackCat (aka ALPHV) operation. "It appears that Cicada3301 ransomware primarily targets small to medium-sized businesses (SMBs), likely through opportunistic attacks that exploit vulnerabilities as the initial access vector," cybersecurity company Morphisec said in a technical report shared with The Hacker News. Written in Rust and capable of targeting both Windows and Linux/ESXi hosts, Cicada3301 first emerged in June 2024, inviting potential affiliates to join their ransomware-as-a-service (RaaS) platform via an advertisement on the RAMP underground forum. A notable aspect of the ransomware is that the executable embeds the compromised user's credentials, which are then used to run PsExec , a legitimate tool that makes it possible to run programs remotely. Cicada3301's similarities with BlackCat also extend t...

The threat actors behind the BlackByte ransomware group have been observed likely exploiting a recently patched security flaw impacting VMware ESXi hypervisors, while also leveraging various vulnerable drivers to disarm security protections. "The BlackByte ransomware group continues to leverage tactics, techniques, and procedures (TTPs) that have formed the foundation of its tradecraft since its inception, continuously iterating its use of vulnerable drivers to bypass security protections and deploying a self-propagating, wormable ransomware encryptor," Cisco Talos said in a technical report shared with The Hacker News. The exploitation of CVE-2024-37085 , an authentication bypass vulnerability in VMware ESXi that has also been weaponized by other ransomware groups, is a sign that the e-crime group is pivoting from established approaches. BlackByte made its debut in the second half of 2021 and is purported to be one of the autonomous ransomware offshoots to have emerged...

A recently patched security flaw impacting VMware ESXi hypervisors has been actively exploited by "several" ransomware groups to gain elevated permissions and deploy file-encrypting malware. The attacks involve the exploitation of CVE-2024-37085 (CVSS score: 6.8), an Active Directory integration authentication bypass that allows an attacker to obtain administrative access to the host. "A malicious actor with sufficient Active Directory (AD) permissions can gain full access to an ESXi host that was previously configured to use AD for user management by re-creating the configured AD group ('ESXi Admins' by default) after it was deleted from AD," Broadcom-owned VMware noted in an advisory released in late June 2024. In other words, escalating privileges on ESXi to the administrator was as simple as creating a new AD group named "ESX Admins" and adding any user to it, or renaming any group in the domain to "ESX Admins" and adding a user...

Cisco has released patches to address a maximum-severity security flaw impacting Smart Software Manager On-Prem (Cisco SSM On-Prem) that could enable a remote, unauthenticated attacker to change the password of any users, including those belonging to administrative users. The vulnerability, tracked as CVE-2024-20419 , carries a CVSS score of 10.0. "This vulnerability is due to improper implementation of the password-change process," the company said in an advisory. "An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow an attacker to access the web UI or API with the privileges of the compromised user." The shortcoming affects Cisco SSM On-Prem versions 8-202206 and earlier. It has been fixed in version 8-202212. It's worth noting that version 9 is not susceptible to the flaw. Cisco said there are no workarounds that resolve the issue, and that it's not aware of any malicio...
