Hackers Can Exploit Samsung Pre-Installed Apps to Spy On Users.




Multiple critical security flaws have been disclosed in Samsung's pre-installed Android apps, which, if successfully exploited, could have allowed adversaries access to personal data without users' consent and take control of the devices.
"The impact of these bugs could have allowed an attacker to access and edit the victim's contacts, calls, SMS/MMS, install arbitrary apps with device administrator rights, or read and write arbitrary files on behalf of a system user which could change the device's settings," Sergey Toshin, founder of mobile security startup Oversecured, said in an analysis published Thursday.
Toshin reported the flaws to Samsung in February 2021, following which patches were issued by the manufacturer as part of its monthly security updates for April and May. The list of the seven vulnerabilities is as follows -

CVE-2021-25356 - third-party authentication bypass in Managed Provisioning

CVE-2021-25388 - Arbitrary app installation vulnerability in Knox Core

CVE-2021-25390 - Intent redirection in PhotoTable

CVE-2021-25391 - Intent redirection in Secure Folder

CVE-2021-25392 - Possible to access notification policy file of DeX

CVE-2021-25393 - Possible to read/write access to arbitrary files as a system user (affects the Settings app)

CVE-2021-25397 - Arbitrary file write in TelephonyUI

The impact of these flaws means they could be exploited to install arbitrary third-party apps, grant the device admin privileges to delete other installed applications or steal sensitive files, read or write arbitrary files as a system user, and even execute privileged actions.
In a proof-of-concept (PoC) demo, Oversecured established that it was possible to leverage the intent redirection flaws in PhotoTable and Secure Folder to hijack the apps' permissions to access the SD card and read contacts stored in the phone. Likewise, by exploiting CVE-2021-25397 and CVE-2021-25392, an attacker could overwrite the file storing SMS/MMS messages with malicious content and steal data from user notifications.
Samsung device owners are recommended to apply the latest firmware updates from the company to avoid any potential security risks.

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.

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 ...
