GitHub Actions and Azure virtual machines (VMs) are being leveraged for cloud-based cryptocurrency mining, indicating sustained attempts on the part of malicious actors to target cloud resources for illicit purposes. "Attackers can abuse the  runners  or servers provided by GitHub to run an organization's pipelines and automation by maliciously downloading and installing their own cryptocurrency miners to gain profit easily," Trend Micro researcher Magno Logan  said  in a report last week. GitHub Actions ( GHAs ) is a continuous integration and continuous delivery (CI/CD) platform that allows users to automate the software build, test, and deployment pipeline. Developers can leverage the feature to create workflows that build and test every pull request to a code repository, or deploy merged pull requests to production. Both Linux and Windows runners are hosted on  Standard_DS2_v2  virtual machines on Azure and come with two vCPUs and 7GB of memory. T...

It's not a new concept that Office 365, Salesforce, Slack, Google Workspace or Zoom, etc., are amazing for enabling the hybrid workforce and hyper-productivity in businesses today. However, there are three main challenges that have arisen stemming from this evolution: (1) While SaaS apps include a host of native security settings, they need to be hardened by the security team of the organization. (2) Employees are granting 3rd party app access to core SaaS apps that pose potential threats to the company. (3) These SaaS apps are accessed by different devices without their device hygiene score even being checked.  1 — Misconfiguration Management It's not an easy task to have every app setting properly configured — at all times. The challenge lies within how burdensome this responsibility is — each app has tens or hundreds of security settings to configure, in addition to thousands of user roles and permission in a typical enterprise, compounded by the many compliance industry...

The $540 million hack of Axie Infinity's  Ronin Bridge  in late March 2022 was the consequence of one of its former employees getting tricked by a fraudulent job offer on LinkedIn, it has emerged.  According to a report from  The Block  published last week citing two people familiar with the matter, a senior engineer at the company was duped into applying for a job at a non-existent company, causing the individual to download a fake offer document disguised as a PDF. "After what one source described as multiple rounds of interviews, a Sky Mavis engineer was offered a job with an extremely generous compensation package," the Block reported. The offer document subsequently acted as a conduit to deploy malware designed to breach Ronin's network, ultimately facilitating one of the crypto sector's biggest hacks to date. "Sky Mavis employees are under constant advanced spear-phishing attacks on various social channels and one employee was compromised," t...

The maintainers of the official third-party software repository for Python have begun imposing a new two-factor authentication (2FA) condition for projects deemed "critical." "We've begun rolling out a 2FA requirement: soon, maintainers of critical projects must have 2FA enabled to publish, update, or modify them," Python Package Index (PyPI)  said  in a tweet last week. "Any maintainer of a critical project (both 'Maintainers' and 'Owners') are included in the 2FA requirement," it  added . Additionally, the developers of critical projects who have not previously turned on 2FA on PyPi are being offered free hardware security keys from the Google Open Source Security Team. PyPI, which is run by the Python Software Foundation, houses more than 350,000 projects, of which over  3,500 projects  are said to be tagged with a "critical" designation. According to the repository maintainers, any project accounting for the top 1% ...

A newly observed phishing campaign is leveraging the recently disclosed Follina security vulnerability to distribute a previously undocumented backdoor on Windows systems. "Rozena is a backdoor malware that is capable of injecting a remote shell connection back to the attacker's machine," Fortinet FortiGuard Labs researcher Cara Lin  said  in a report this week. Tracked as  CVE-2022-30190 , the now-patched Microsoft Windows Support Diagnostic Tool (MSDT) remote code execution vulnerability has come under heavy exploitation in recent weeks ever since it came to light in late May 2022. The starting point for the latest attack chain observed by Fortinet is a weaponized  Office document  that, when opened, connects to a  Discord CDN URL  to retrieve an HTML file (" index.htm ") that, in turn, invokes the diagnostic utility using a PowerShell command to download next-stage payloads from the same CDN attachment space. This includes the Rozena implant (...

Cybersecurity researchers are drawing attention to an ongoing wave of attacks linked to a threat cluster tracked as Raspberry Robin that's behind a Windows malware with worm-like capabilities.  Describing it as a "persistent" and "spreading" threat, Cybereason  said  it observed a number of victims in Europe. The infections involve a worm that propagates over removable USB devices containing malicious a .LNK file and leverages compromised QNAP network-attached storage (NAS) devices for command-and-control. It was  first documented  by researchers from Red Canary in May 2022. Also codenamed  QNAP worm  by Sekoia, the malware leverages a legitimate Windows installer binary called "msiexec.exe" to download and execute a malicious shared library (DLL) from a compromised QNAP NAS appliance. "To make it harder to detect, Raspberry Robin leverages process injections in three legitimate Windows system processes," Cybereason researcher Loïc Cast...

LockBit ransomware attacks are constantly evolving by making use of a wide range of techniques to infect targets while also taking steps to disable endpoint security solutions. "The affiliates that use LockBit's services conduct their attacks according to their preference and use different tools and techniques to achieve their goal," Cybereason security analysts Loïc Castel and Gal Romano  said . "As the attack progresses further along the kill chain, the activities from different cases tend to converge to similar activities." LockBit, which operates on a ransomware-as-a-service (RaaS) model like most groups, was first observed in September 2019 and has since emerged as the most dominant ransomware strain this year, surpassing other well-known groups like  Conti ,  Hive , and  BlackCat . This involves the malware authors licensing access to affiliates, who execute the attacks in exchange for using their tools and infrastructure and earn as much as 80% of ea...
