CHINESE HACKERS CARRIED OUT COUNTRY-LEVEL WATERING HOLE ATTACK. 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 resources at one fell swoop." According to the researchers, the group injected malicious JavaScript code into the official government websites associated with the data center in order to conduct watering hole attacks. Although LuckyMouse has been spotted using a widely used Microsoft office Vulnerability (CVE-2017-11882) to weaponize Office documents in the past, researchers have no proofs of this technique being used in this particular attack against the data center. The initial attack vector used in the attack against the data center is unclear, but researchers believe LuckyMouse possibly had conducted watering hole or phishing attacks to compromise accounts belonging to employees at the national data center. The attack against the data center eventually infected the targeted system with a piece of malware called HyperBro, a Remote Access Trojan (RAT) deployed to maintain persistence in the targeted system and for remote administration. "There were traces of HyperBro in the infected data center from mid-November 2017. Shortly after that different users in the country started being redirected to the malicious domain update.iaacstudio[.]com as a result of the waterholing of government websites," the researchers said in a blog post published on Thursday 14 June 2018. "These events suggest that the data center infected with HyperBro and the waterholing campaign are connected." As a result of the waterholing attack, the compromised government websites redirected the country's visitors to either penetration testing suite Browser Exploitation Framework (BeEF) that focuses on the web browser, or the ScanBox reconnaissance framework, which perform the same tasks as a keylogger. The main command and control (C&C) server used in this attack is hosted on an IP address which belongs to a Ukrainian ISP, specifically to a MikroTik router running a firmware version released in March 2016. Researchers believe the Mikrotik router was explicitly hacked for the campaign in order to process the HyperBro malware's HTTP requests without detection.

UGANDA ELECTORAL COMMISSION TO ELIMINATE NATIONAL IDENTIFICATION CARDS (IDs) FOR 2021 GENERAL ELECTIONS.

The elimination of using National IDs (Ndagamuntu) for the 2021 elections should not have come as a surprise. One would be very NAIVE to think that Bobi Wine has not prepared for this in his Business Plan under the RISK section. It is public knowledge that our EC is not independent.  It is also public knowledge that Military Dictator Yoweri Museveni will never lose an election. What stunned us this morning is when we noticed that on social media, people were mocking Bobi with his "get your Ndagamuntu".  We are on record for saying to all Our readers that the National ID is like Apartheid in South Africa. Students of History would know how those IDs were being used to arrest people, deny them jobs, deny them basic services. Consequently, Bobi was not wrong and will never be wrong on the Ndagamuntu. Except the ones attacking him and mocking him forget that in Uganda, now, no National ID (Ndagamuntu), no service.  If you have not been denied registering your child i...

Here is Why Our Utterances For Praying Jesus And God To Come Liberate Ugandans, May Be Misplaced. This Phrase is like inform of a Letter To Some Categorized Section Of Ugandans.

https://m.facebook.com/yusufosuta/photos/a.1896701010557789/2070383359856219/?type=3 OPEN LETTER TO NRM SUPPORTERS - NATIONAL ROBBERS MOVEMENT. .................................................................................. Last week of March, a friend told me to pray for Uganda.  I told him that he was an Idiot and we have prayed for too long and we are still hungry and sick and Jesus is not coming soon to liberate us. He then ignored the STUPID and sent me a picture we all now know.  It got me totally messed up.  This guy was telling me to pray then sends a picture of men bowing down in blood.  He might have meant guns but I blocked him because his utterances of praying for Uganda were misplaced. I unblocked him 3 weeks later and asked him about praying and assassinations.  His reply "eithrr prayers or guns or both". I hate violence with a passion.  So he is now blocked in like FOREVER. Do you feel safe?  Do not feel safe. Uganda regim...
