Messing with previously-known vulnerabilities for cyberattacks has never been out-of-fashion for threat actors. Throwing light on the growing threat, seven mobile browsers have been found to be impacted by an address spoofing vulnerability that can open the door for malware delivery, phishing, and disinformation campaigns. The affected browsers are Apple Safari, Opera Touch/Mini, Yandex, Bolt Browser, RITS Browser, and UC Browser.

Widespread phishing attacks designed to steal Microsoft Office 365 and Facebook credentials have also been observed in the last 24 hours. While the Office 365 operation has reached tens of thousands of emails by spoofing applications such as Microsoft Office, Microsoft Teams, and Zoom, the phishing on Facebook is launched via Messenger.

Moreover, the Nefilim ransomware gang made headlines for posting sensitive information stolen from eyecare giant Luxottica. The attack had occurred on September 18.

Top Malware Reported in the Last 24 Hours

Basecamp abused
Hackers have started using Basecamp project management solution to distribute malware or steal login credentials. In one instance, the product was used to distribute BazarLoader executables.

Top Scams Reported in the Last 24 Hours

Spoofed domains
The FBI has issued an alert to warn about the potential use of spoofed US Census Bureau domains for phishing attacks and credential thefts. So far, the FBI has observed 65 malicious domains registered similar to the US Census Bureau. Some of these spoofed websites are Censusburea[.]com or census-gov[.]us. Following the rise in this trend, the agency has provided a list of recommendations to detect legitimate-looking fake domains.

Phishing campaigns
Two massive phishing campaigns aimed at Microsoft Office 365 users and Facebook Messenger have been uncovered by researchers.
