A hack-for-hire group that was  first exposed in 2019  has expanded its focus to set its sights on entities with business or political ties to Russia. Dubbed Void Balaur , the cyber mercenary collective has a history of launching cyberattacks against biotechnology and telecom companies since 2015. As many as 3,500 victims have been reported as of November 2021. "Void Balaur [...] primarily dabbles in cyber espionage and data theft, selling the stolen information to anyone willing to pay," Trend Micro  noted  at the time. Attacks conducted by the group are typically both generic and opportunistic and are aimed at gaining unauthorized access to widely-used email services, social media, messaging, and corporate accounts. Earlier this June, Google's Threat Analysis Group (TAG) took the wraps off a set of  credential theft attacks  targeting journalists, European politicians, and non-profit's mounted by the threat actor. "Void Balaur also goes after targ...

An SMS-based phishing campaign is targeting customers of Indian banks with information-stealing malware that masquerades as a rewards application. The Microsoft 365 Defender Research Team said that the messages contain links that redirect users to a sketchy website that triggers the download of the fake banking rewards app for ICICI Bank. "The malware's RAT capabilities allow the attacker to intercept important device notifications such as incoming messages, an apparent effort to catch two-factor authentication (2FA) messages often used by banking and financial institutions," researchers Shivang Desai, Abhishek Pustakala, and Harshita Tripathi  said . Additionally, the malware is equipped with the ability to steal SMSes, potentially enabling the attacker to swipe 2FA codes sent as text messages and gain unauthorized access to victim accounts. Like other social engineering attacks, familiar brand logos and names are used in the smishing message as well as the rogue a...

Microsoft on Thursday warned of a consumer-facing attack that made use of rogue OAuth applications deployed on compromised cloud tenants to ultimately seize control of Exchange servers and spread spam. "The threat actor launched credential stuffing attacks against high-risk accounts that didn't have multi-factor authentication (MFA) enabled and leveraged the unsecured administrator accounts to gain initial access," the Microsoft 365 Defender Research Team said. The unauthorized access to the cloud tenant permitted the adversary to register a malicious OAuth application and grant it elevated permissions, and eventually modify Exchange Server settings to allow inbound emails from specific IP addresses to be routed through the compromised email server. "These modifications to the Exchange server settings allowed the threat actor to perform their primary goal in the attack: sending out spam emails," Microsoft  said . "The spam emails were sent as part of a...

A new wave of a mobile surveillance campaign has been observed targeting the Uyghur community as part of a long-standing spyware operation active since at least 2015, cybersecurity researchers disclosed Thursday. The intrusions, originally attributed to a threat actor named  Scarlet Mimic  back in January 2016, is said to have encompassed 20 different variants of the Android malware, which were disguised as books, pictures, and an audio version of the Quran. The malware, while relatively unsophisticated from a technical standpoint, comes with extensive capabilities to steal sensitive data from an infected device, send SMS messages on the victim's behalf, make phone calls, and track their locations. Additionally, it allows the recording of incoming and outgoing phone calls as well as surrounding audio. "All this makes it a powerful and dangerous surveillance tool," Israeli cybersecurity firm Check Point  said  in a technical deepdive, calling the spyware  M...

A malicious NPM package has been found masquerading as the legitimate software library for Material Tailwind, once again indicating attempts on the part of threat actors to distribute malicious code in open source software repositories. Material Tailwind is a  CSS-based framework  advertised by its maintainers as an "easy to use components library for Tailwind CSS and Material Design." "The malicious Material Tailwind npm package, while posing as a helpful development tool, has an automatic post-install script," Karlo Zanki, security researcher at ReversingLabs,  said  in a report shared with The Hacker News. This script is engineered to download a password-protected ZIP archive file that contains a Windows executable capable of running PowerShell scripts. The now-removed rogue package, named  material-tailwindcss , has been downloaded 320 times to date, all of which occurred on or after September 15, 2022. In a tactic that's becoming increasingly common,...

Last month Tech Crunch reported that  payment terminal manufacturer Wiseasy had been hacked . Although Wiseasy might not be well known in North America, their Android-based payment terminals are widely used in the Asia Pacific region and hackers managed to steal passwords for 140,000 payment terminals. How Did the Wiseasy Hack Happen? Wiseasy employees use a cloud-based dashboard for remotely managing payment terminals. This dashboard allows the company to perform a variety of configuration and management tasks such as managing payment terminal users, adding or removing apps, and even locking the terminal.  Hackers were able to gain access to the Wiseasy dashboard by infecting employee's computers with malware. This allowed hackers to gain access to two different employee's dashboards, ultimately leading to a massive harvesting of payment terminal credentials once they gained access. Top Lessons Learned from the Wiseasy Hack 1 — Transparency isn't always the best policy...

Researchers have disclosed a new severe Oracle Cloud Infrastructure (OCI) vulnerability that could be exploited by users to access the virtual disks of other Oracle customers. "Each virtual disk in Oracle's cloud has a unique identifier called OCID," Shir Tamari, head of research at Wiz,  said  in a series of tweets. "This identifier is not considered secret, and organizations do not treat it as such." "Given the OCID of a victim's disk that is not currently attached to an active server or configured as shareable, an attacker could 'attach' to it and obtain read/write over it," Tamari added. The cloud security firm, which dubbed the tenant isolation vulnerability " AttachMe ," said Oracle  patched the issue  within 24 hours of responsible disclosure on June 9, 2022. Accessing a volume using the CLI without sufficient permissions At its core, the vulnerability is rooted in the fact that a disk could be attached to a compute ...

As many as 350,000 open source projects are believed to be potentially vulnerable to exploitation as a result of a security flaw in a Python module that has remained unpatched for 15 years. The open source repositories span a number of industry verticals, such as software development, artificial intelligence/machine learning, web development, media, security, and IT management. The shortcoming, tracked as  CVE-2007-4559  (CVSS score: 6.8), is rooted in the tarfile module, successful exploitation of which could lead to code execution from an arbitrary file write. "The vulnerability is a path traversal attack in the extract and extractall functions in the tarfile module that allow an attacker to overwrite arbitrary files by adding the '..' sequence to filenames in a TAR archive," Trellix security researcher Kasimir Schulz  said  in a writeup. Originally disclosed in August 2007, the bug has to do with how a specially crafted tar archive can be leveraged to overwr...

A now-patched critical security flaw affecting Atlassian Confluence Server that came to light a few months ago is being actively exploited for illicit cryptocurrency mining on unpatched installations. "If left unremedied and successfully exploited, this vulnerability could be used for multiple and more malicious attacks, such as a complete domain takeover of the infrastructure and the deployment information stealers, remote access trojans (RATs), and ransomware," Trend Micro threat researcher Sunil Bharti  said  in a report. The issue, tracked as  CVE-2022-26134  (CVSS score: 9.8), was addressed by the Australian software company in June 2022. In one of the infection chains observed by the cybersecurity company, the flaw was leveraged to download and run a shell script ("ro.sh") on the victim's machine, which, in turn, fetched a second shell script ("ap.sh"). The malicious code is designed to update the  PATH variable  to include additional paths...

An unknown attacker targeted tens of thousands of unauthenticated Redis servers exposed on the internet in an attempt to  install a cryptocurrency miner . It's not immediately known if all of these hosts were successfully compromised. Nonetheless, it was made possible by means of a "lesser-known technique" designed to trick the servers into writing data to arbitrary files – a case of  unauthorized access  that was first documented in September 2018. "The general idea behind this exploitation technique is to configure Redis to write its file-based database to a directory containing some method to authorize a user (like adding a key to '.ssh/authorized_keys'), or start a process (like adding a script to '/etc/cron.d')," Censys  said  in a new write-up. The attack surface management platform said it uncovered evidence (i.e., Redis commands) indicating efforts on part of the attacker to store malicious  crontab entries  into the file "/var/...

In what's the latest crypto heist to target the decentralized finance (DeFi) space, hackers have stolen digital assets worth around $160 million from crypto trading firm Wintermute . The hack involved a series of unauthorized transactions that transferred USD Coin, Binance USD, Tether USD, Wrapped ETH, and 66 other cryptocurrencies to the  attacker's wallet . The company said that its centralized finance (CeFi) and over-the-counter (OTC) operations have not been impacted by the security incident. It did not disclose when the hack took place. The digital asset market maker, which provides liquidity to more several exchanges and crypto platforms, warned of disruption to its services in the coming days, but stressed that it's "solvent with twice over that amount in equity left." "We are (still) open to treat[ing] this as a white hat, so if you are the attacker – get in touch," the company's founder and CEO, Evgeny Gaevoy,  said  in a tweet. Detai...

For cybersecurity professionals, it is a huge challenge to separate the "good guys" from the "villains". In the past, most cyberattacks could simply be traced to external cybercriminals, cyberterrorists, or rogue nation-states.  But not anymore . Threats from within organizations – also known as "insider threats" – are increasing and cybersecurity practitioners are feeling the pain.  Traditional perimeter defenses are not designed to prevent these attacks. They also struggle to keep  external  attackers out. Clever hackers continuously find ways in and "weaponize" their trusted status inside the network to compromise sensitive assets and orchestrate larger attacks. And an increasing number of enterprise resources – applications, devices, data, and even people – now live outside the perimeter. It's difficult to protect these assets with legacy approaches, much less fortify the perimeter to keep attackers out completely. How can you protect your organization in th...
