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.
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.
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.
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.

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.
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.
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).
Netskope, CrowdStrike, Okta, and Proofpoint are joining together to help better safeguard organizations by delivering an integrated, Zero Trust security strategy that is designed to protect today’s dynamic and remote working environments at scale.
