Welcome to our weekly roundup, where we share what you need to know about the cybersecurity news and events that happened over the past few days. This week, learn about why Zoom has released an update for its Linux, Mac, and Windows apps that removes the meeting ID from the app’s title bar. Also, read about Trend Micro’s latest research on cloud-specific security, with examples of threats and risks that organizations could face when migrating to the cloud or using cloud services.
This week, Trend Micro released new research findings concerning cloud security, a major area of concern for enterprises of all sizes. The research confirms the role of both human errors and complex deployments in creating cloud-based cyber threats; above all, Trend Micro notes the dangers of cloud misconfiguration to cloud environments.
The National Cyber Security Alliance is hosting a series of webinars for small business owners, and Trend Micro is proud to support this effort with guest speakers sharing threat intelligence and security expertise. The topics will help small companies deal with the challenges of COVID-19, including sessions on telework, digital spring cleaning, e-commerce security, how to avoid COVID-19 scams and more.
An ongoing phishing campaign is reeling in victims with a recycled Cisco security advisory that warns of a critical vulnerability. The campaign urges victims to “update,” only to steal their credentials for Cisco’s Webex web conferencing platform instead. The campaign is looking to leverage the wave of remote workers who have come to rely on online conferencing tools like Webex and other platforms.
Cloud migrations are happening every day and analysts predict over 75% of mid-size to large enterprises will migrate a workload to the cloud by 2021 – but how can you make sure your workload is successful? In this multi-part blog series, Trend Micro explores best practices, forward thinking, and use cases around creating a successful cloud migration from multiple perspectives.
Trend Micro recently found a Coinminer bundled with the legitimate installer of video conferencing app Zoom, luring users who want to install the software but end up downloading a malicious file. The compromised files are assumed to come from fraudulent websites. Trend Micro has been working with Zoom to ensure that they are able to communicate this to their users appropriately.
Trend Micro’s Managed XDR (MxDR) and Incident Response (IR) teams recently investigated an incident involving a company that was hit by the Nefilim ransomware, which was initially discovered in March 2020. What makes Nefilim especially devious is that the threat actors behind the attack threaten to release the victim’s stolen data on an online leak site.
Video conferencing service Zoom has released an update for its Linux, Mac, and Windows apps that removes the meeting ID from the app’s title bar. The update comes after the company’s users have often leaked their meeting IDs, and even meeting passwords, when sharing screenshots of their meetings on social media.
A malicious Microsoft Excel 4.0 Macro sheet with a suspicious formula that is set as “Very Hidden” was submitted by a customer and further analyzed by Trend Micro researchers. The sheet is not readily accessible via the Microsoft Excel User Interface (UI) due to a feature documented in the Microsoft website that allows users to hide sheets. The compromised files were commonly used as an attachment in spam.
Attackers looking to exploit CVE-2020-0688, a critical Microsoft Exchange flaw patched by Microsoft in February 2020, don’t have to look hard to find a server they can attack: according to an internet-wide scan performed by Rapid7 researchers, there are at least 315,000 and possibly as many as 350,000 vulnerable on-premise Exchange servers (out of 433,464 total) out there.
A campaign that targets misconfigured Docker Daemon API ports through Kinsing malware was reported by security researchers from Aqua Security. The campaign exploited the ports to run an Ubuntu container. According to the researchers, Kinsing malware’s strings revealed that it is a Golang-based Linux agent.
Trend Micro researchers detected a new courier service-themed malicious spam campaign that uses ACE files as attachments. The samples were gathered from Trend Micro’s honeypot. The email poses as a shipment arrival notification with a fake receipt attached. It then convinces receivers to download the attachment by asking them to check if the address on the receipt is correct.blo
Trend Micro’s recent cloud research provides examples of threats and risks organizations could face when migrating to the cloud or using cloud services. No matter the cloud service or platform, the common theme is that misconfiguration continues to be one of the major pitfalls of cloud security, affecting both companies who subscribe to cloud services and users of software that are hosted on the cloud.
A researcher is sounding the alarm over what he believes could be a novel attack vector which allows a hacker to manipulate a PowerPoint file to download and begin the installation of malware, simply by hovering over a hypertext link. The technique does require a victim to accept one pop-up dialogue box to run or install a program. For those reasons, Microsoft does not consider this a vulnerability.
Lower costs, improved efficiencies and faster time to market are some of the primary benefits of transitioning to the cloud. However, it’s not done overnight. It can take years to move complete data centers and operational applications to the cloud and the benefits won’t be fully realized until most functional data have been transitioned.
A company advertising a remote access tool frequently used by criminals and nation-state hackers may be serving as a front for a Chinese hacking group, according to research published by BlackBerry Cylance. In a report on remote access trojans (RAT), researchers detail an Android malware variant, which they call PWNDROID4, that can be used to monitor targets’ phone calls, record audio, send and receive text messages, and track victims’ GPS location.
