Cybersecurity researchers have discovered a new Linux variant of a ransomware strain known as Play (aka Balloonfly and PlayCrypt) that's designed to target VMware ESXi environments. "This development suggests that the group could be broadening its attacks across the Linux platform, leading to an expanded victim pool and more successful ransom negotiations," Trend Micro researchers said in a report published Friday. Play, which arrived on the scene in June 2022, is known for its double extortion tactics, encrypting systems after exfiltrating sensitive data and demanding payment in exchange for a decryption key. According to estimates released by Australia and the U.S., as many as 300 organizations have been victimized by the ransomware group as of October 2023. Statistics shared by Trend Micro for the first seven months of 2024 show that the U.S. is the country with the highest number of victims, followed by Canada, Germany, the U.K., and the Netherlands.

Two Russian nationals have pleaded guilty in a U.S. court for their participation as affiliates in the LockBit ransomware scheme and helping facilitate ransomware attacks across the world. The defendants include Ruslan Magomedovich Astamirov, 21, of Chechen Republic, and Mikhail Vasiliev, 34, a dual Canadian and Russian national of Bradford, Ontario. Astamirov was arrested in Arizona by U.S. law enforcement agencies in May 2023. Vasiliev, who is already wanted for similar charges in Canada, was sentenced to nearly four years in jail. He was subsequently extradited to the U.S. last month. The development comes more than two months after the U.K. National Crime Agency (NCA) unmasked a 31-year-old Russian national named Dmitry Yuryevich Khoroshev as the administrator and developer of the LockBit ransomware operation. LockBit, which is estimated to have attacked over 2,500 entities since its appearance towards the end of 2019, raking in at least approximately $500 million in ranso

As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.

An emerging ransomware-as-a-service (RaaS) operation called Eldorado comes with locker variants to encrypt files on Windows and Linux systems. Eldorado first appeared on March 16, 2024, when an advertisement for the affiliate program was posted on the ransomware forum RAMP, Singapore-headquartered Group-IB said. The cybersecurity firm, which infiltrated the ransomware group, noted that its representative is a Russian speaker and that the malware does not overlap with previously leaked strains such as LockBit or Babuk. "The Eldorado ransomware uses Golang for cross-platform capabilities, employing Chacha20 for file encryption and Rivest Shamir Adleman-Optimal Asymmetric Encryption Padding (RSA-OAEP) for key encryption," researchers Nikolay Kichatov and Sharmine Low said . "It can encrypt files on shared networks using Server Message Block (SMB) protocol." The encryptor for Eldorado comes in four formats, namely esxi, esxi_64, win, and win_64, with its data leak

Threat actors with suspected ties to China and North Korea have been linked to ransomware and data encryption attacks targeting government and critical infrastructure sectors across the world between 2021 and 2023. While one cluster of activity has been associated with the ChamelGang (aka CamoFei), the second cluster overlaps with activity previously attributed to Chinese and North Korean state-sponsored groups, cybersecurity firms SentinelOne and Recorded Future said in a joint report shared with The Hacker News. This includes ChamelGang's attacks aimed at the All India Institute of Medical Sciences (AIIMS) and the Presidency of Brazil in 2022 using CatB ransomware , as well as those targeting a government entity in East Asia and an aviation organization in the Indian subcontinent in 2023. "Threat actors in the cyber espionage ecosystem are engaging in an increasingly disturbing trend of using ransomware as a final stage in their operations for the purposes of financia

Microsoft on Friday said it will disable its much-criticized artificial intelligence (AI)-powered Recall feature by default and make it an opt-in. Recall , currently in preview and coming exclusively to Copilot+ PCs on June 18, 2024, functions as an "explorable visual timeline" by capturing screenshots of what appears on users' screens every five seconds, which are subsequently analyzed and parsed to surface relevant information. But the feature, meant to serve as some sort of an AI-enabled photographic memory, was met with instantaneous backlash from the security and privacy community, which excoriated the company for having not thought through enough and implementing adequate safeguards that could prevent malicious actors from easily gaining a window into a victim's digital life. The recorded information could include screenshots of documents, emails, or messages containing sensitive details that may have been deleted or shared temporarily using disappearing

Google has announced plans to store Maps Timeline data locally on users' devices instead of their Google account effective December 1, 2024. The changes were originally announced by the tech giant in December 2023, alongside updates to the auto-delete control when enabling Location History by setting it to three months by default, down from the previous limit of 18 months. Google Maps Timeline , as the name implies, helps users track routes, trips, and places they have been to over time, assuming Location History and Web & App Activity settings are enabled. But with the latest change to host the data on users' devices, the company has also said that it's removing the ability to view them on the web. "Since the data shown on your Timeline comes directly from your device, Timeline won't be available on Maps on your computer after your data is moved to your phone," Google noted in a support document. The updates, it added, are gradually rolling out to

Researchers have discovered two novel attack methods targeting high-performance Intel CPUs that could be exploited to stage a key recovery attack against the Advanced Encryption Standard (AES) algorithm. The techniques have been collectively dubbed  Pathfinder  by a group of academics from the University of California San Diego, Purdue University, UNC Chapel Hill, Georgia Institute of Technology, and Google. "Pathfinder allows attackers to read and manipulate key components of the branch predictor, enabling two main types of attacks: reconstructing program control flow history and launching high-resolution Spectre attacks," Hosein Yavarzadeh, the lead author of the  paper , said in a statement shared with The Hacker News. "This includes extracting secret images from libraries like libjpeg and recovering encryption keys from AES through intermediate value extraction." Spectre is the name given to a  class of side-channel attacks  that exploit  branch prediction

Update: The U.K. National Crime Agency (NCA) has confirmed the takedown of LockBit infrastructure. Read here for more details . An international law enforcement operation has led to the seizure of multiple darknet domains operated by  LockBit , one of the most prolific ransomware groups, marking the latest in a long list of digital takedowns. While the full extent of the effort, codenamed  Operation Cronos , is presently unknown, visiting the group's .onion website displays a seizure banner containing the message "The site is now under the control of law enforcement." Authorities from 11 countries, Australia, Canada, Finland, France, Germany, Japan, the Netherlands, Sweden, Switzerland, the U.K., and the U.S., alongside Europol participated in the joint exercise. Malware research group VX-Underground, in a  message  posted on X (formerly Twitter), said the websites were taken down by exploiting a critical security flaw impacting PHP ( CVE-2023-3824 , CVSS score: 9.8

Efficient communication is a cornerstone of business success. Internally, making sure your team communicates seamlessly helps you avoid friction losses, misunderstandings, delays, and overlaps. Externally, frustration-free customer communication is directly correlated to a positive customer experience and higher satisfaction.  However, business communication channels are also a major target for cybercriminals. In recent years, especially since the pandemic, the number of cyberattacks has skyrocketed.  Statistics show  that last year alone, the number of hacks shot up by 38%. Worse, it still takes a business 277 days on average to identify a breach, causing a loss of $4.35 on average. So, how can businesses safeguard their communication channels against hackers, while still providing the best possible experience for customers and maintaining team productivity? Here's everything you need to know – and which  mistakes you need to avoid . Use Secure Platforms  To begin with, there is

With breaches making the headlines on an almost weekly basis, the cybersecurity challenges we face are becoming visible not only to large enterprises, who have built security capabilities over the years, but also to small to medium businesses and the broader public. While this is creating greater awareness among smaller businesses of the need to improve their security posture, SMBs are often left facing a gap in the market, unable to find security tooling that is both easy for them to use and which they can afford. When we consider the needs of SMBs, we need to focus both on the development of threat intelligence, which is necessary to understand and identify the threats being faced, as well  as the tools used to provide protection . NTTSH has built a pedigree of over 20 years' experience in the research and curation of threat intelligence as well as the development of capabilities and products which leverage its threat intelligence to protect customers. After many years of focus on

The ransomware industry surged in 2023 as it saw an alarming 55.5% increase in victims worldwide, reaching a staggering 4,368 cases.  Figure 1: Year over year victims per quarter The rollercoaster ride from explosive growth in 2021 to a momentary dip in 2022 was just a teaser—2023 roared back with the same fervor as 2021, propelling existing groups and ushering in a wave of formidable newcomers. Figure 2: 2020-2023 ransomware victim count LockBit 3.0 maintained its number one spot with 1047 victims achieved through the  Boeing  attack, the Royal Mail Attack, and more.  Alphv  and  Cl0p  achieved far less success, with 445 and 384 victims attributed to them, respectively, in 2023.  Figure 3: Top 3 active ransomware groups in 2023 These 3 groups were heavy contributors to the boom in ransomware attacks in 2023, but they were not the sole groups responsible. Many attacks came from emerging ransomware gangs such as  8Base , Rhysida, 3AM, Malaslocker,  BianLian , Play,  Akira , and o

A new Android backdoor has been discovered with potent capabilities to carry out a range of malicious actions on infected devices. Dubbed  Xamalicious  by the McAfee Mobile Research Team, the malware is so named for the fact that it's developed using an open-source mobile app framework called Xamarin and abuses the operating system's accessibility permissions to fulfill its objectives. It's also capable of gathering metadata about the compromised device and contacting a command-and-control (C2) server to fetch a second-stage payload, but only after determining if it fits the bill. The second stage is "dynamically injected as an assembly DLL at runtime level to take full control of the device and potentially perform fraudulent actions such as clicking on ads, installing apps, among other actions financially motivated without user consent," security researcher Fernando Ruiz  said . The cybersecurity firm said it identified 25 apps that come with this active thr
