How to Protect Against Office 365 Takeovers local Iran time, with Microsoft observing peak password-spray activity between 7:30 a.m. вЂњMicrosoft assesses this targeting supports Iranian government tracking of adversary security services and maritime shipping in the Middle East to enhance their contingency plansвЂ¦Gaining access to commercial satellite imagery and proprietary shipping plans and logs could help Iran compensate for its developing satellite program.вЂќДЄlso, the group is most active between Sunday and Thursday between 7:30 a.m. вЂњThis activity likely supports the national interests of the Islamic Republic of Iran based on pattern-of-life analysis, extensive crossover in geographic and sectoral targeting with Iranian actors, and alignment of techniques and targets with another actor originating in Iran,вЂќ the company noted. That dovetails with IranвЂ™s past attacks against shipping and maritime targets and overall goals, according to Microsoft. For instance, the attacks have specifically gone after companies that make military-grade radars, drone technology, satellite systems, emergency response communication systems, geographic information systems (GIS) and spatial analytics, Microsoft said, along with the ports and transportation companies. Once more is known about the attackers, Microsoft will give it a permanent name.ДЇor now though, thereвЂ™s evidence that points to the threat actors being Iranian, it said. The groupвЂ™s вЂњDEVвЂќ-based name is just MicrosoftвЂ™s temporary designation standing for a cluster of developing activity. вЂњThis allows DEV-0343 to validate active accounts and passwords, and further refine their password-spray activity.вЂќ Alleged Links to Iran вЂњThe operators typically target two Exchange endpoints вЂ“ Autodiscover and ActiveSync вЂ“ as a feature of the enumeration/password spray tool they use,вЂќ according to Microsoft.

Emulation of FireFox (most common) or Chrome browsers in password spray campaigns.

Extensive inbound traffic from Tor IP addresses for password spray campaigns.

This use of the proxy addresses makes developing indicators or compromise (IoCs) difficult, but the patterns that Microsoft has observed in the attacks include: These services are often enabled through malicious browser plugins.вЂќ This technique has been enabled by the emergence of services providing huge numbers of residential IP addresses.

вЂњOften, threat groups randomize the user agent they are using as well as IP address. вЂњChanging the IP address for every password attempt is becoming a more common technique among sophisticated threat groups,вЂќ according to the writeup. On average, each attack uses between 150 and 1,000+ unique addresses, Microsoft said, in an elaborate effort to obfuscate the operational infrastructure. The attacks for now are being carried out using an emulated Firefox or Chrome browser, and rotating IP addresses hosted on a Tor proxy network, according to the analysis. However, вЂњDEV-0343 continues to evolve their techniques to refine its attacks,вЂќ the computing giant warned. So far, the campaign has targeted about 250 specific organizations that use MicrosoftвЂ™s cloud-based Office suite, with less than 20 of them suffering compromise, according to the company. In this case, the attackers typically mount attacks on вЂњdozens to hundreds of accountsвЂќ within each targeted organization, Microsoft said, and have been seen trying thousands of credential combinations against each account.

Password-spraying is the process of trying a list of user names and a series of different passwords against online accounts in hopes of finding a match and gaining access to password-protected accounts. It stated cyberattackers are вЂњconducting extensive password sprayingвЂќ against Office 365 accounts. Microsoft, which began tracking the activity in late July 2021, detailed the attacks in an alert released Monday, adding that the culprits appear to be bent on espionage and have ties to Iran. The threat actorвЂ™s goal is Microsoft Office 365 account takeovers. and Israeli defense technology companies, Persian Gulf ports of entry and global maritime transportation companies with ties to the Middle East. A new threat actor, dubbed DEV-0343, has been spotted attacking U.S.
