Netskope Threat Labs publishes a monthly summary blog post of the top threats we are tracking on the Netskope platform. The purpose of this post is to provide strategic, actionable intelligence on active threats against enterprise users worldwide.
A now fixed zero-day elevation of privilege (EoP) vulnerability in Microsoft Outlook (CVE-2023-23397) allows attackers to send craft emails to exploit Outlook. The vulnerability does not require user interaction to be exploited and runs even before the email is visualized in the preview pane of Outlook, which makes this vulnerability even more dangerous.
Late last year, the EU Parliament formally adopted a new Directive, NIS2, updating and superseding the existing NIS Directive which helped the organisations responsible for Europe’s critical national infrastructure to better understand, manage, and reduce their cybersecurity risk.
The Netskope Security team is happy to announce the official release of our newest Cloud Threat Exchange plugin built in-house, which now allows users to pull threat data discovered by SecLytics. This integration leverages the SecLytics Bulk API to allow users to pull identified URL, IP, and CIDR block indicators of behavior (IoBs) into Cloud Exchange.
BlackSnake is a ransomware-as-a-service (RaaS) group that first appeared in a hacking forum in August 2022, where the operators were seeking affiliates and stating that they would take 15% of the profit, which is below the typical average of 20-30%. On February 28, 2023, a new variant of BlackSnake was spotted, and is notable for having a clipper module that targets cryptocurrency users.
Today, Netskope partnered with the Cloud Security Alliance to release the Data Loss Prevention (DLP) and Data Security Survey Report, a survey focused on data protection needs in cloud and hybrid work environments. Unsurprisingly, the report found that the biggest pain point organizations identify with trying to modernize their data protection strategy is that current DLP deployments show limitations when it comes to cloud and remote work use cases, and they are a nightmare to manage.
Another day, another cyber espionage campaign exploiting two legitimate and well-known cloud services to deliver the malicious payload. Once again, this campaign was unearthed by researchers at Sentinel One, and it is aimed to distribute the Remcos Remote Access Tool (yet another example of a remote control tool used for malicious purposes) through the DBatLoader to target predominantly organizations in Eastern Europe.
Innovation and regulation are two important factors that have a significant impact on the growth of any industry, including information security. The question of whether regulation inhibits or inspires innovation is a contentious one, and there are compelling arguments on both sides.
When I talk to customers and partners about Cloud Threat Exchange (CTE), I immediately say, “I’m not in marketing, and didn’t see the future—so I misnamed the module. I should have named it Cloud Data Exchange.” Why do I say this? Because, as Netskope and Cloud Exchange have matured, the number of use cases the module can fulfill has naturally grown beyond the initial vision. How so?
Netskope Threat Labs is tracking a 17x increase in traffic to malicious web pages hosted on DigitalOcean in the last six months. This increase is attributed to new campaigns of a known tech support scam that mimics Windows Defender and tries to deceive users into believing that their computer is infected.
