Netdata is a daemon that collects data in realtime (per second) and presents a web site to view and analyze them. The presentation is also real-time and full of interactive charts that precisely render all collected values.

It has been designed to be installed on every system, without disrupting the applications running on it:

It will just use some spare CPU cycles (check Performance).
It will use the memory you want it have (check Memory Requirements).
Once started and while running, it does not use any disk I/O, apart its logging (check Log Files). Of course it saves its DB to disk when it exits and loads it back when it starts.

You can use it to monitor all your systems and applications. It will run on Linux PCs, servers or embedded devices.

Out of the box, it comes with plugins that collect key system metrics and metrics of popular applications.

Really wanted to share this with all, but image upload doesnt seems to be working.

Have you see this type of cabling? Visited one office and found that this cable is connected from wall jack to an airport extreme, one end to the internet port and the second to the lan port! I have no clue why and how this worked. Something really new to me!

Feeling lucky!
Got a call from the vendor and he mentioned that there was some confusion about my machine, apparently the mobo and processor replacement was for another customer, and for my machine, it was just adding thermal paste as it was overheating. Got the machine back spending only $40 for checking for 2 days and fixing the issue Much better than spending around $500+ for the change. Thank god, machine works fine now, will update my xen and start working on few things.

Researchers crack new version of CryptXXX ransomware. An updated decryptor tool can help users recover files affected by the CryptXXX ransomware program.

Their updated tool is called RannohDecryptor and can be downloaded from the company's support website @ https://support.kaspersky.com/viruses/utility#rannohdecryptor

Just saw this on another site, not sure if shared already!

Just read this topic on Spiceworks.

Was curious and tried it on my home machine, and happy to see that webroot caught that as soon as the program started and passed all tests!

"A hacker going by the handle BuggiCorp is selling a zero-day vulnerability affecting all Windows OS versions that can allow an attacker to elevate privileges for software processes to the highest level available in Windows, known as SYSTEM," writes Softpedia. The zero-day is up for sale on a Russian underground hacking forum, and is currently available for $90,000 -- after it was initially up for $95,000. The hacker is saying he'll sell the zero-day to one person only, who'll receive its source code and a working demo. Two videos are available, one showing the hacker exploit Windows 10 with the May 2016 security patch, and another one bypassing all EMET features. While security experts think the zero-day may be overpriced, they think the hacker will find a buyer regardless.

DNS record will help prevent unauthorized SSL certificates. Starting in September, certificate authorities will be required to honor a new DNS record that specifies who is authorized to issue certificates for a domain.

In a few months, publicly trusted certificate authorities will have to start honoring a special Domain Name System (DNS) record that allows domain owners to specify who is allowed to issue SSL certificates for their domains.

The Certification Authority Authorization (CAA) DNS record became a standard in 2013 but didn't have much of a real-world impact because certificate authorities (CAs) were under no obligation to conform to them.

The record allows a domain owner to list the CAs that are allowed to issue SSL/TLS certificates for that domain. The reason for this is to limit cases of unauthorized certificate issuance, which can be accidental or intentional, if a CA is compromised or has a rogue employee.

Under existing industry rules created by the CA/Browser Forum, an organization that combines major browser vendors and CAs, certificate authorities must validate that requests for SSL certificates originate from domain owners themselves or from someone in control of those domains.

This ownership verification is typically automated and involves asking the domain owner to create a DNS TXT record with a specific value or to upload authorization codes at a specific location in their site's structure, thus proving their control over the domain.

However, hacking into a website could also give an attacker the ability to pass such verifications and request a valid certificate for the compromised domain from any certificate authority. Such a certificate could later be used to launch man-in-the-middle attacks against users or to direct them to phishing pages.
