Horrible Call Quality With Samsung Galaxy s10 Lineup

The Samsung Galaxy s10 lineup of phones are great machines, the specs are great and the hard within them are amazing. However what in the world is going on with the call quality of these phones?

People have mentioned that it could be a carrier issue with ATT, however others like myself have Version and are experiencing the same issue.

Troubleshooting the issue:

What I have experienced during phone calls with people and they make some sort of high pitched tone the phone would magnify and focus on that high pitched sound, background noise would also be enhanced with ear piercing sounds which would cause me move my phone away from my ear. After some research I have found … Read the rest

Microsofts April 9th security update impacts some antivirus software vendors

People have been noticing that Microsoft’s recent April 9th security update is causing some problems with a few antivirus vendors like Sophos, Avira, Avast, McAfee and some others. 

Microsoft has stated that the the Security Update is causing end user computers to have very slow startup times bad performance and be unresponsive and even causing systems to fail to boot.

“Microsoft is working on a resolution and will provide an update in an upcoming release,” according to Microsoft.

Currently the root cause of the issue by the April 9th security patch is unclear. But both McAfee and Avast suggest that the problems are tied to the change Microsoft made within the Windows Client-Server Runtime Subsystem (csrss.exe). This CSRSS process is a vital part of Windows and is responsible for many windows functions.

Currently there is no fix for this issue.

Microsoft Outlook.com Email Accounts Breached By Hackers

Many users received a notification from Microsoft Outlook.com letting them know about accounts being breached by hackers. 

A Motherboard report said that the breach is “much worse” than what was reported. The hackers were able to access emails and attachments and that the hackers were able to access a large number of Outlook, MSN and Hotmail email accounts.

“We addressed this scheme, which affected a limited subset of consumer accounts, by disabling the compromised credentials and blocking the perpetrators’ access,” a Microsoft spokesperson meanwhile said in a statement.

“Upon awareness of this issue, Microsoft immediately disabled the compromised credentials, prohibiting their use for any further unauthorized access,” Microsoft said. “Our data indicates that account-related information (but not the content of any emails) could have been viewed, but Microsoft has no indication why that information was viewed or how it may have been used.”

Windows Zero-Day Exploit

Windows has recently released a patch for a vulnerability exploit in the windows operating system which was unknown to many people until last week. The vulnerability would allow a hacker to open a door for full system control.

Discovered by Vasily Berdnikov and Boris Larin of Kaspersky Lab on St. Patrick’s Day this year, the flaw (CVE-2019-0859) is a use-after-free issue in the Windows kernel that allows local privilege escalation (LPE). It’s being used in advanced persistent threat (APT) campaigns targeting 64-bit versions of Windows (from Windows 7 to older builds of Windows 10).

TrickBot phishing scams for 2019 tax season

Hackers are once again using the TrickBot banking trojan to exploit the tax season by pushing malicious Microsoft Excel spreadsheet documents via spam campaigns. IBM noticed a few different types of phishing emails are pretending to be from ADP and Paychex which are malicious emails spreading the TrickBot trojan.

“Taxpayers should be on constant guard for these phishing schemes, which can be tricky and cleverly disguised to look like it’s the IRS,” said IRS Commissioner Chuck Rettig. “Watch out for emails and other scams posing as the IRS, promising a big refund or personally threatening people. Don’t open attachments and click on links in emails. Don’t fall victim to phishing or other common scams.”

An IBM security person mentioned:

“Once TrickBot is installed on a potentially vulnerable device and can reach other devices on the network, it can further spread and pivot,” researchers with IBM X-Force warned in a Monday
