Microsoft says that Windows 10 updates released in late September are causing Windows taskbar flicker issues and app instability. "After installing updates released September 20, 2022 or later, taskbar elements might flicker and cause system instability," Microsoft said in a new issue added to the Windows health dashboard on Friday.

Ivanti worked with cybersecurity experts and surveyed 6,500 executive leaders, cybersecurity professionals, and office workers to understand the perception of today's cybersecurity threats and find out how companies are preparing for yet-unknown future threats. The report revealed that despite 97% of leaders and security professionals reporting their organization is as prepared or more prepared to defend against cybersecurity attacks than they were a year ago, one in five wouldn't bet a chocolate bar they could prevent a damaging breach.

A previously undocumented data wiper named CryWiper is masquerading as ransomware, but in reality, destroys data beyond recovery in attacks against Russian mayor's offices and courts. "In the fall of 2022, our solutions detected attempts by a previously unknown Trojan, which we named CryWiper, to attack an organization's network in the Russian Federation," explains the new report by Kaspersky.

New research has disclosed what's being called a security vulnerability in Microsoft 365 that could be exploited to infer message contents due to the use of a broken cryptographic algorithm. Office 365 Message Encryption is a security mechanism used to send and receive encrypted email messages between users inside and outside an organization without revealing anything about the communications themselves.

Microsoft Office 365 Message Encryption claims to offer a way "To send and receive encrypted email messages between people inside and outside your organization." Office 365 Message Encryption relies on a strong cipher, AES, but WithSecure says that's irrelevant because ECB is weak and vulnerable to cryptanalysis regardless of the cipher used.

We're not quite sure what to call it right now, so we referred to it in the headline by the hybrid name Microsoft Office 365. The web-based versions of the Office tools don't have the same feature set as the full apps, so any results we might obtain are unlikely to align with how most business users of Office, ah, 365 have configured Word, Excel, Outlook and friends on their Windows laptops.

WithSecure researchers are warning organizations of a security weakness in Microsoft Office 365 Message Encryption that could be exploited by attackers to obtain sensitive information. OME, which is used by organizations to send encrypted emails internally and externally, utilizes the Electronic Codebook implementation - a mode of operation known to leak certain structural information about messages.

Security researchers at WithSecure, previously F-Secure Business, found that it is possible to partially or fully infer the contents of encrypted messages sent through Microsoft Office 365 due to the use of a weak block cipher mode of operation. Organizations use Office 365 Message Encryption to send or receive emails, both external and internal, to ensure confidentiality of the content from destination to source.

Microsoft has begun to kill off the Microsoft Office brand, with plans to rebrand its Office.com and Office cloud-based apps to Microsoft 365 in the near future. In 2020, Microsoft rebranded Office 365 to Microsoft 365 and started to heavily push the subscription-based productivity suite to both the enterprise and consumers.
