Firefox browser has 45 such internal locally-hosted about pages , some of which are listed below that you might have noticed or used at some point: about:config — panel to modify Firefox preferences and critical settings. about:downloads — your recent downloads done within Firefox. about:memory — shows the memory usage of Firefox. about:newtab — the default new tab page. about:plugins — lists all your plugins as well as other useful information. about:privatebrowsing — open a new private window. about:networking — displays networking information.

Chinese Hackers Carried Out Country-Level Watering Hole Attack

June 14, 2018Swati Khandelwal
Cybersecurity researchers have uncovered an espionage campaign that has targeted a national data center of an unnamed central Asian country in order to conduct watering hole attacks. The campaign is believed to be active covertly since fall 2017 but was spotted in March by security researchers from Kaspersky Labs, who have attributed these attacks to a Chinese-speaking threat actor group called LuckyMouse . LuckyMouse, also known as Iron Tiger, EmissaryPanda, APT 27 and Threat Group-3390, is the same group of Chinese hackers who was found targeting Asian countries with Bitcoin mining malware early this year. The group has been active since at least 2010 and was behind many previous attack campaigns resulting in the theft of massive amounts of data from the directors and managers of US-based defense contractors. This time the group chose a national data center as its target from an unnamed country in Central Asia in an attempt to gain "access to a wide range of government

During the past week, the security teams at several unnamed Polish banks discovered malicious executables on the workstations of several banks. The KNF confirmed that their internal systems had been compromised by someone " from another country, " although no specifications were provided. After downloads of suspicious files that were infecting various banking systems had been discovered on the regulator's servers, the KNF decided to take down its entire system " in order to secure evidence.
