With single item recovery and mailbox retention, customers can recover items in a mailbox upon inadvertent or malicious premature deletion. Customers can rollback mail messages deleted within 14 days by default, configurable up to 30 days.
Additional customer configurations of these retention policies within the Exchange Online service allow for:. Exchange Online Protection scans incoming email and attachments in real-time both entering and exiting the system. This is enabled by default and has filtering customizations available. Messages containing ransomware or other known or suspected malware are deleted. You can configure admins to receive notifications when this occurs.
SharePoint Online and OneDrive for Business Protection have built in features that help protect against ransomware attacks. Versioning : As versioning retains a minimum of versions of a file by default and can be configured to retain more, if the ransomware edits and encrypts a file, a previous version of the file can be recovered.
Recycle bin : If the ransomware creates a new encrypted copy of the file, and deletes the old file, customers have 93 days to restore it from the recycle bin. Preservation Hold library : Files stored in SharePoint or OneDrive sites can be retained by applying retention settings. When a document with versions is subject to retention settings, versions get copied to the Preservation Hold library and exist as a separate item. If a user suspects their files have been compromised, they can investigate file changes by reviewing the retained copy.
File Restore can then be used to recover files within the last 30 days. Microsoft Teams data is protected by the controls and recovery mechanisms available in these services. The second domain is the people that make up Microsoft the organization, and the corporate infrastructure owned and controlled by Microsoft to execute the organizational functions of a business.
Microsoft's approach to securing its corporate estate is Zero Trust, implemented using our own products and services with defenses across our digital estate. Additional features in Microsoft extend the risk mitigations available in domain 1 to further protect the assets in this domain. Versioning : If ransomware encrypted a file in place, as an edit, the file can be recovered up to the initial file creation date using version history capabilities managed by Microsoft. Recycle bin : If the ransomware created a new encrypted copy of the file, and deleted the old file, customers have 93 days to restore it from the recycle bin.
After 93 days, there is a day window where Microsoft can still recover the data. After this window, the data is permanently deleted. Database availability groups DAG help provide protection against corruption of mailbox data in Exchange Online.

While these themed attacks are still higher than they were in early February and are likely to continue as long as COVID persists, this pattern of changing lures prove to be outliers, and the vast majority of the threat landscape falls into typical phishing and identity compromise patterns. Cybercriminals are adaptable and always looking for the best and easiest ways to gain new victims.
Commodity malware attacks, in particular, are looking for the biggest risk-versus-reward payouts. The industry sometimes focuses heavily on advanced attacks that exploit zero-day vulnerabilities, but every day the bigger risk for more people is being tricked into running unknown programs or Trojanized documents.
Likewise, defenders adapt and drive up the cost of successful attacks. Starting in April, we observed defenders greatly increasing phishing awareness and training for their enterprises, raising the cost and complexity barrier for cybercriminals targeting their employees. Cybercriminals are looking for the easiest point of compromise or entry. One way they do this is by ripping lures from the headlines and tailoring these lures to geographies and locations of their intended victims.
This is consistent with the plethora of phishing studies that show highly localized social engineering lures. In enterprise-focused phishing attacks this can look like expected documents arriving and asking the user to take action. During the COVID outbreak, cybercriminals closely mimicked the local developments of the crisis and the reactions to them. Here we can see the global trend of concern about the outbreak playing out with regional differences.
Below we take a deeper look at three countries and how local events landed in relation to observed attacks. Attacks targeting the United Kingdom initially followed a trajectory similar to the global data, but spiked early, appearing to be influenced by the news and concerns in the nation. Figure 4. Trend of COVID themed attacks in the United Kingdom showing unique encounters distinct malware files and total encounters number of times the files are detected.
In the latter half of March, the United Kingdom increased transparency and information to the public as outbreak protocols were implemented, including the closure of schools. The attacks dropped considerably all the way to April 5, when Queen Elizabeth II made a rare televised address to the nation. Data shows a corresponding increase in attacks until April 12, the day the Prime Minister was discharged from the hospital.
The level of themed attacks then plateaued at about 3, daily attacks until roughly the end of April. The UK government proclaimed the country had passed the peak of infections and began to restore a new normalcy.
Attacks took a notable drop to around 2, daily attacks.
