2 min read

eSentire Threat Intelligence is aware of a recently discovered code execution technique affecting hosts running the Windows 10 operating system [1]. The Threat Intelligence team assesses with medium confidence that this technique does not pose an immediate threat to customers. Public samples examined by the eSentire Threat Intelligence team showed that antivirus solutions such as Windows Defender have released signatures to detect and block the DeepLink technique. At this time, eSentire has not observed threats employing this technique against eSentire customers. Should this change, eSentire Threat Intelligence will reassess the severity of this threat.
