How Just Opening A Site In Safari Could Have Hacked Your Apple macOS.

Hacking apple macos exploit
Earlier this week Dropbox team unveiled details of three critical vulnerabilities in Apple macOS operating system, which altogether could allow a remote attacker to execute malicious code on a targeted Mac computer just by convincing a victim into visiting a malicious web page.
The reported vulnerabilities were originally discovered by Syndis, a cybersecurity firm hired by Dropbox to conduct simulated penetration testing attacks as Red Team on the company's IT infrastructure, including Apple software used by Dropbox.
The vulnerabilities were discovered and disclosed to Apple security team in February this year, which were then patched by Apple just over one month later with the release of its March security updates. DropBox applauded Apple for its quick response to its bug report.
According to DropBox, the vulnerabilities discovered by Syndis didn't just affect its macOS fleet, but also affected all Safari users running the latest version of the web browser and operating system at the time.

Here's the list of the three reported (then-zero-day) vulnerabilities:
The first flaw (CVE-2017-13890) that resided in CoreTypes component of macOS allowed Safari web browser to automatically download and mount a disk image on visitors’ system through a maliciously crafted web page.
The second flaw (CVE-2018-4176) resided in the way Disk Images handled .bundle files, which are applications packaged as directories. Exploiting the flaw could have allowed an attacker to launch a malicious application from mounted disk using a bootable volume utility called bless and its --openfolder argument.
The third vulnerability (CVE-2018-4175) involved a bypass of macOS Gatekeeper anti-malware, allowing a maliciously crafted application to bypass code signing enforcement and execute a modified version of Terminal app leading to arbitrary commands execution.
As shown in the proof-of-concept video demonstration, the researchers were able to create a two-stage attack by chaining together all the three vulnerabilities to take control of a Mac computer just by convincing a victim into visiting a malicious web page with Safari.
"The first stage includes a modified version of the Terminal app, which is registered as a handler for a new file extension (.workingpoc). In addition, it would contain a blank folder called "test.bundle" which would be set as the default "openfolder" which automatically would open /Applications/Terminal.app without prompt," DropBox says in its blog post.
"The second stage includes an unsigned shellscript with the extension ".workingpoc" which is then executed within the running Terminal application without prompt." Apple released security updates on March 29 that included the security fixes for the three vulnerabilities. So, you just need to make sure that you install all monthly security updates regularly in order to protect your systems against any threat.

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

By Editor
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...

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...

Okello lost his wife 20 years ago and decided to only focus on their Mateo, Yona and Yosefu. 20 years later, Okello had 7 acres of land, a successful poultry business, and sinotrucks for hire. Early this year, Okello got a call telling him that one of his trucks knocked a boda boda. Okello decided to rush to see if he could sort it out before police became involved. Unfortunately, he never made it, as he was entering the main road, another trailer rammed into him and killed him instantly.   After Okello had been laid to rest, his sons sat down and divided the property amongst themselves. However, of late, Yosefu the last born has started complaining that he was cheated, and he wants to be given something else because most of the chicken in the chicken business died of a fever.   Can ...
