Security Awareness – Current Phishing Campaign Leverages Fake Outlook Web App

A new phishing scam is using the likeness of Microsoft Outlook Web App to steal credentials. Researchers at Mailguard observed a recent phishing campaign from an unknown group of cyber criminals seeking to gain access to user credentials. The email asks users to ‘validate your account’ by clicking on a nefarious link and entering your password. After clicking the link, victims are directed to a mimicked version of the Outlook Web App login page and asked to provide their username and password.

FBI FLASH: APT Group Exploiting 0-day in FatPipe WARP, MPVPN, and IPVPN Software

The FBI has published a TLP:WHITE FLASH examining the activities of an APT group exploiting a zero-day in FatPipe WARP, MPVPN, and IPVPN software. According to the FLASH, APT actors have been observed exploiting this vulnerability going back to at least May 2021. The vulnerability allowed the threat actors “to gain access to an unrestricted file upload function to drop a webshell for exploitation activity with root access, leading to elevated privileges and potential follow-on activity.” The FLASH includes further technical details regarding this activity and lists recommended mitigations.

The Top Domains that Threat Actors Prefer

Amidst thousands of top-level domains (TLD) available, researchers at Palo Alto Networks have identified the most widely exploited TLDs by threat actors. The researchers discovered threat actors prefer a small group of 25 TLDs, accounting for 90 percent of all malicious websites. Threat actors prefer exploiting .com and .net TLDs because they appear more legitimate to victims and thus improve success rates. The TLDs that spread the most malware include .ga, .xyz, .cf, ,tk, .org, and .ml.

CISA Publishes Cybersecurity Incident and Vulnerability Response Playbooks

The Cybersecurity and Infrastructure Security Agency (CISA) just released two playbooks for federal executive branch agencies to serve as guides on how “to respond to vulnerabilities and incidents” impacting their networks. The playbooks provide operational guidelines for planning and conducting cybersecurity incident and vulnerability response activities. Illustrated decision trees and step by step instructions for both incident and vulnerability response are also included. The new operational procedures fulfill the directives issued to CISA by the White House’s Executive Order 14028.

FBI Portal Suffers Compromise

The notion that every organization is vulnerable to a cyber attack gained further credence this weekend when the FBI suffered a breach to one of its email servers. On Friday, a threat actor exploited a software vulnerability in the FBI’s Law Enforcement Enterprise Portal (LEEP), which is used for communication with state and local law enforcement partners, disseminating over 100,000 fraudulent emails. The adversary discovered the misconfiguration in the LEEP portal’s registration process, allowing them to send out emails from an fbi.gov address.

Threat Actor Provided APT and Ransomware Gangs Initial Access to Australian Businesses, according to BlackBerry Report

A recent report from security researchers at Blackberry has discovered an initial access broker, identified as Zebra2104, with links to cyber criminal groups and advanced persistent threat (APT) actors involved in ransomware and phishing activities. The report notes that after Zebra2104 gained initial access to a victim’s device or network and established a reliable backdoor into the network. The actor then advertised their access to these compromised systems on the Dark Web. Zebra2104 provided access to ransomware groups such as MountLocker and Phobos as well as the StrongPity APT.
