September's Patch Tuesday is here and it brings, among other things, fixes from Microsoft for one security bug that miscreants have used to fully take over Windows systems along with details of a second vulnerability that, while not yet under attack, has already been publicly disclosed. "Seeing as this vulnerability was reported to Microsoft by four different cybersecurity companies, it is highly likely that it is being leveraged extensively in the wild - specifically by APT groups and malware authors - to gain elevated privileges," Bharat Jogi, director of vulnerability and threat research at Qualys, told The Register.

Reports of such malicious events can come from a range of sources and those that are identified by security event and incident management and extended detection and response systems are automatically collected into alerts, which then become incidents.

Microsoft says an Iranian state-sponsored threat group it tracks as DEV-0270 has been abusing the BitLocker Windows feature in attacks to encrypt victims' systems.

Microsoft's threat intelligence division on Wednesday assessed that a subgroup of the Iranian threat actor tracked as Phosphorus is conducting ransomware attacks as a "Form of moonlighting" for personal gain. "DEV-0270 leverages exploits for high-severity vulnerabilities to gain access to devices and is known for the early adoption of newly disclosed vulnerabilities," Microsoft said.
Microsoft appears to have fixed a problem that saw its Defender antivirus program identify apps based on the Chromium browser engine and/or Electron JavaScript framework as malware, and suggest users remove them. Chat in Microsoft's forums, helped along by a volunteer expert, diagnosed the issue as a false positive produced by Windows Defender, possibly due to recent browser updates somehow confusing matters.
A bad Microsoft Defender signature update mistakenly detects Google Chrome, Microsoft Edge, Discord, and other Electron apps as 'Win32/Hive.
