Trouble with i3 Systems' CLOMO MDM, affecting DoCoMo's corporate mobile phones and vaccination record tablets

It was revealed on the 18th that a problem has occurred in the mobile device management system "CLOMO MDM" of i3 Systems. According to NTT DoCoMo, some of DoCoMo's corporate terminals are in an unusable state.

"CLOMO MDM" is a solution that can centrally manage smartphones and tablets introduced by companies. The provider, i3 Systems, announced that it had the largest market share in the domestic MDM market for 10 consecutive years from FY2011 to FY2020. It is said that it has been widely adopted by companies, medical institutions, government agencies, educational institutions, etc., such as Obayashi Corporation, Saga Prefectural Government, Tokio Marine & Nichido Fire Insurance, Noevir Holdings, and Jikei University School of Medicine.

I3 Systems has not yet announced the problem at 14:50 on the 18th. We will inform you later in this magazine as soon as the details become clear.

Although it is reported in some reports that "it cannot be used with DoCoMo's corporate mobile phones," CLOMO MDM claims to be carrier-free, and will be added as soon as the impact on KDDI terminals and Softbank terminals is known.

On the morning of the 18th, the official Twitter account of the government-operated vaccination recording system (VRS) displayed "Locked by CLOMO MDM" on some tablets provided by DoCoMo, indicating that it is in a situation where it can not be operated. .. In addition to canceling the remote on the DoCoMo side, it is tweeted that it can be recovered by restarting the terminal.

[Addition 2021/10/18 15:26] According to NTT DoCoMo, this event occurs when the Android device is under the control of CLOMO MDM and "local lock" is set. According to a report that DoCoMo received from i3 Systems, it affected up to 77 companies, and it also affected lines other than DoCoMo.

If the administrator unlocks it, it can be used again, and at 11:02 on the 18th, the unlock command has been sent from the i3 Systems side all at once.

[Addition 2021/10/18 17:41] According to KDDI, so far, the company's users have not reported any similar events.

[Addition 2021/10/18 18:02] SoftBank replied that the company's users did not report anything like this event.

[Addition 2021/10/18 17:49] According to i3 Systems, it was explained that this event occurred from 22:00 on the 17th to 7:00 on the 18th.

"CLOMO" is designed to be automatically locked when any problem is detected by Google's Android Enterprise function. This time, a problem was detected by the Android Enterprise function on the device of the "CLOMO" user, and an event occurred in which it was unintentionally forcibly locked. The cause is being investigated, including the possibility that it is caused by the services of i3 Systems and the services of other companies that cooperate with it.

In addition to DoCoMo lines, it is also occurring in terminals that subscribe to other carrier lines and terminals that support only Wi-Fi.
