We’re excited to invite our community of infosec analysts and engineers to the second annual InfoSec Jupyterthon taking place on December 2-3, 2021. This is an online event organized by Open Threat Research Forge together with Microsoft Threat Intelligence Center (MSTIC).
Microsoft has observed multiple Iranian threat actors targeting the IT services sector in attacks that aim to steal sign-in credentials belonging to downstream customer networks to enable further attacks.
Sophisticated cyberattacks are on the rise, with email phishing as the most common attack vector. Microsoft has been working hard to understand these types of attacks and create solutions that help prevent, detect, and remediate vulnerability at the most basic point of attack, the user.
Over the past year, the Microsoft Threat Intelligence Center (MSTIC) has observed a gradual evolution of the tools, techniques, and procedures employed by malicious network operators based in Iran.
We developed a cloud-based machine learning system that, when queried by a device, intelligently predicts if it is at risk, then automatically issues a more aggressive blocking verdict to protect the device, thwarting an attacker’s next steps.
HTML smuggling, a highly evasive malware delivery technique that leverages legitimate HTML5 and JavaScript features, is increasingly used in email campaigns that deploy banking malware, remote access Trojans (RATs), and other payloads related to targeted attacks.
Microsoft has detected exploits being used to compromise systems running the ZOHO ManageEngine ADSelfService Plus software versions vulnerable to CVE-2021-40539 in a targeted campaign. Microsoft Threat Intelligence Center (MSTIC) attributes this campaign with high confidence to DEV-0322.
Microsoft found a vulnerability (CVE-2021-30892) that could allow an attacker to bypass System Integrity Protection (SIP) in macOS. We shared our findings with Apple via coordinated vulnerability disclosure, and a fix was released October 26.
The Microsoft Threat Intelligence Center (MSTIC) has detected nation-state activity associated with the threat actor tracked as NOBELIUM, attempting to gain access to downstream customers of multiple cloud service providers (CSP), managed service providers (MSP), and other IT services organizations.
A phishing kit built using pieces of code copied from other kits, some available for sale through publicly accessible scam sellers or are reused and repackaged by other kit resellers, provides rich insight into the state of the economy that drives phishing and email threats today.
MSTIC has observed DEV-0343 conducting extensive password spraying against more than 250 Office 365 tenants, with a focus on United States and Israeli defense technology companies, Persian Gulf ports of entry, or global maritime transportation companies with business presence in the Middle East.
In-depth analysis of newly detected NOBELIUM malware: a post-exploitation backdoor that Microsoft Threat Intelligence Center (MSTIC) refers to as FoggyWeb. NOBELIUM uses FoggyWeb to remotely exfiltrate the configuration database of compromised AD FS servers, decrypted token-signing certificate, and token-decryption certificate, as well as to download and execute additional components.
