Why Network Peering & Interconnections Matter

In previous blogs on the Netskope NewEdge network, we’ve discussed concepts including Secure Access Service Edge (SASE) architecture and why counting data centers alone is meaningless when trying to understand cloud service coverage. Now that we’ve laid the foundation it seems like a good time to get into what’s needed in terms of architecting the actual network and the connections required.

Migrating from On-prem Proxies to the Cloud

Recently, a Fortune 500 customer asked us to migrate 5 million lines of URL policies into our cloud solution. This configuration included frequently used websites like Office.com, Linkedin.com, and Box.com as well as hundreds of other URLs and domains that were no longer reachable or registered anymore. Our first question to the customer was, “Help us understand why you would want to do that?”, in the context of migrating their entire configuration.

Blogspot Serves as a COVID-19 Scamming Hotspot

Attackers were quick to exploit the COVID-19 pandemic, with coronavirus-themed phishing campaigns, Trojans delivering ransomware and backdoors, and other scams. Netskope Threat Labs have been keeping a close eye on the threat landscape and tracking COVID-related campaigns throughout this unprecedented time.

GCP OAuth Token Hijacking in Google Cloud-Part 2

Imagine you’ve protected your production Google Cloud environment from compromised credentials, using MFA and a hardware security key. However, you find that your GCP environment has been breached through the hijacking of OAuth session tokens cached by gcloud access. Tokens were exfiltrated and used to invoke API calls from another host. The tokens were refreshed by the attacker and did not require MFA. Detecting the breach via Stackdriver was confusing, slowing incident response.

The Impact of Lockdown Remote Working-A Conversation with the Law Firm Herbert Smith Freehills

Recently I participated in a webinar with Toks Oladuti (Netskope customer, and senior IT security manager at the international law firm Herbert Smith Freehills), and my colleague Neil Thacker (Netskope’s CISO EMEA). The conversation was hosted by Janet Day, a long-time technology consultant to the legal industry. During the webinar, we touched on a lot of topics and I was particularly interested to hear Toks’ stories of HSF’s journey to the cloud.

Tracking COVID-19's Effect on Remote Working by Industry and Geography

The COVID-19 pandemic caused an abrupt and dramatic shift to remote work that has lasted five months so far and is expected to continue into 2021 as companies like Google have extended their work from home policies through July 2021. In this blog, we examine how geography and industry effect who works remotely during the COVID-19 pandemic.

Leaky O365 Links: Accidental Exposure in O365 Link Sharing

Did you know that the default “copy link” option in O365 personal accounts generates a public shared link with edit permissions? In this edition, we will cover how link sharing in O365 can lead to the accidental internal and public exposure of sensitive data.

A Big Catch: Cloud Phishing from Google App Engine and Azure App Service

Threat actors are leveraging top tier cloud apps to host phishing baits. Netskope Threat Labs has identified an ongoing O365 phishing campaign hosted in Google App Engine with the credential harvester mostly hosted in Azure App Service. This phishing campaign typically targets O365 users via phishing emails with a direct link or attachment.

Netskope Threat Coverage: GuLoader

GuLoader is a sophisticated malware downloader that stores its payloads in Google Drive and Microsoft OneDrive. In addition to using popular cloud apps to evade network-based detection, it uses anti-VM techniques to evade sandbox analysis. Since it was first discovered in December 2019, GuLoader has become one of the top malware delivery mechanisms observed in the wild. It is used by multiple threat actors to deliver a variety of threats, most commonly remote access Trojans (RATs).
