A new software security threat is currently being monitored, where malicious PDF files are sent around via email. For the moment, there is no automated protection available.
Please read on to understand how you can protect yourself and the infrastructure of SES against the malware:
Malicious PDF files may come from any source – attached to emails that you will identify as SPAM but also, what is more important and dangerous, attached to emails that seem legitimate and relevant (e.g. CVs sent as job applications). At present, there is no Anti-Virus software on the market which is able to detect the new malware.
The SES Security Team strongly encourages all SES users to proceed with extreme caution:
Do not open any PDF documents that you may have received since this morning. Instead, do not hesitate to send them to IT for examination.
