莱丹见解

Axetris专门从事微技术,并在自己的无尘室中制造红外源等。红外线源是医院中冠状病毒患者使用的呼吸器的一部分。

Unknown persons have registered the domain name us-leister.com in the last few days and thus send e-mails in the name of the Leister Group with fraudulent intentions. Furthermore, e-mails with a spoofed sender address (martin.zingg@leister.com) were sent, which contained very strange-looking requests in the text (CEO Fraud1)

For this reason, we recommend you the following measures:

  • Never respond with "Reply" to emails with such strange-looking content. Always make inquiries via the officially known contact details of the Leister Group. 
  • Checking2 the sender address on incoming emails.
    The correct return addresses for the Leister Group are as follows:
    xxxx.xxxxxx@leister.com
    xxxx.xxxxxx@Leister.in
    xxxx.xxxxxx@Leister.jp
    xxxx.xxxxxx@Leister.it
    xxxx.xxxxxx@Leister.nl
    xxxx.xxxxxx@Leister.be
    xxxx.xxxxxx@Leister.cn
  • Blocking the domain us-Leister.com on your firewalls, proxy servers and mail gateways.

We would like to apologize for any inconveniences caused and hope that this information will make a small contribution to the fight against cybercrime.

1 CEO Fraud is a fraud method in which attackers impersonate a CEO, manager or boss and ask recipients to transfer money to a spe-cific account, for example. If the attacker uses email as a means of communication, CEO fraud is a form of business email compro-mise (BEC).

2 Note: It is not possible to reliably check the email address in the sender line because this display can be falsified (address spoofing). The check must be done with a mouseover (up to Office 2016) and for newer versions via "File - Properties".
