Threat actors associated with financially-motivated hacker groups combined multiple zero-day vulnerabilities and a new web shell to breach up to 100 companies using Accellion's legacy File Transfer Appliance and steal sensitive files. The attacks occurred in mid-December 2020 and involved the Clop ransomware gang and the FIN11 threat group. Unlike previous attacks by these groups, the Clop file-encrypting malware was not deployed.

Sneaky attackers are flipping backslashes in phishing email URLs to evade protections, researchers said. Researchers from GreatHorn report they have observed a nearly 6,000-percent jump in attacks using "malformed URL prefixes" to evade protections and deliver phishing emails that look legit. They look legit, that is, unless you look closely at the symbols used in the prefix before the URL. "The URLs are malformed, not utilizing the normal URL protocols, such as http:// or https://."

A previously undetected piece of malware found on almost 30,000 Macs worldwide is generating intrigue in security circles, and security researchers are still trying to understand precisely what it does and what purpose its self-destruct capability serves. Once an hour, infected Macs check a control server to see if there are any new commands the malware should run or binaries to execute. So far, however, researchers have yet to observe delivery of any payload on any of the infected 30,000 machines. READ MORE...
