Proofpoint has also reported a small increase in the use of HTML attachments to deliver malware. SEE: Password breach: Why pop culture and passwords don’t mix (free PDF) (TechRepublic) Container XLL files, a type of dynamic link library (DLL) file for Excel, have also seen a slight increase in use after Microsoft announced it would disable XL4 macros in 2021. Container files can obscure LNKs, DLLs or executable (.exe) files that lead to the installation of a malicious payload when opened. “When the document is extracted, the user will still have to enable macros for the malicious code to automatically execute, but the file system will not identify the document as coming from the web.”Īttackers can also use container files to distribute payloads directly, Proofpoint said. files will have the MOTW attribute because they were downloaded from the internet, but the document inside, such as a macro-enabled spreadsheet, will not,” Proofpoint said in a press release.

The problem is MOTW can be bypassed by using container file formats such as ISO (.iso), RAR (.rar), ZIP (.zip) and IMG (.img) to send macro-enabled documents. The program cant start because update.dll is. For instance, a faulty application, update.dll has been deleted or misplaced, corrupted by malicious software present on your PC or a damaged Windows registry. Microsoft blocks VBA macros based on a Mark of the Web (MOTW) attribute known as a zone identifier that shows if a file comes from the internet, a restricted source, and, therefore, if it can be trusted. Errors related to update.dll can arise for a few different different reasons.
“Bad actors send macros in Office files to end users who unknowingly enable them, malicious payloads are delivered, and the impact can be severe including malware, compromised identity, data loss, and remote access,” Microsoft said in a blog post addressing the issue. SEE: Mobile device security policy (TechRepublic Premium) Threat actors use social engineering tactics to get users to enable the macros, which are necessary to view the file’s content. XL4 macros are specific to the Excel application but can also be weaponized by threat actors, Proofpoint said.
