Microsoft disables 90% of computer network used by Russian hacker group

 Aided by a series of U.S. court orders and relations with technology providers in other countries, Microsoft said its week-long campaign against the group that runs the Trickbot network will avoid a possible source of interference in the November 3 election. .


"We have destroyed a large part of its infrastructure," said Microsoft corporate vice president Tom Burt in an interview. "The group's ability to infect targets has been significantly reduced."


The hackers responsible for Trickbot infected more than 1 million personal computers, including many within local governments, according to cybersecurity professionals. They then make deals with other groups to install ransomware and other programs on infected machines, security professionals say.


Although there is no evidence that the group has worked with foreign governments, Burt said that Microsoft aimed to reduce the capacity of Trickbot before the election, should Russian spy agencies try to use it to interfere in the American vote or cast doubts. on the election results through data manipulation.

Some security experts who saw little impact on Microsoft's initial efforts to combat Trickbot said this week that the new control servers brought online by the group were having access to the internet blocked, making it more difficult for the group to install new programs on infected computers. .


"Interrupt operations against Trickbot are currently global in nature and have been successful against Trickbot's infrastructure," said Intel 471 Chief Executive Mark Arena. "Despite this, there are still a small number of controllers working based in Brazil, Colombia, Indonesia and Kyrgyzstan who are still able to respond."


The Trickbot group is now asking others to install its software, Arena and others said, and it is hoped that they will be able to rebuild their infrastructure in other ways.


Burt said such efforts to adapt will at least reduce the group's ability to interfere in the US elections.

DDoS Can Mask Security Breaches

Cyber criminals launch low-threshold DDoS attacks— also known as “Dark DDoS”—because they are a cheap and easy way to infiltrate and map a network. Because the attacks are so short – typically less than five minutes in duration – they are usually not detected by security teams or traditional DDoS scrubbing solutions. Because these attacks typically require very little bandwidth to execute, they are nearly impossible to detect without an advanced in-line DDoS protection solution that has granular detection capabilities. Stop denial of service attack In cases where the IT security staff do notice a DDoS attack in progress, the attack often serves as a decoy to distract security staff while hackers stealthily find pathways and test for vulnerabilities within a network. Hackers may install malware to ex-filtrate sensitive data such as email addresses or credit card numbers or corporate intellectual property. In addition, hackers may “own” or “enslave” the network so it can later be ex

Algorithm for troubleshooting computer problems

If you encounter problems with your computer and its hardware, you must act correctly. If the problem is with the hardware, for example, the printer does not print, you should start looking for the problem from that device. First, you need to check the printer's electrical and computer connections. Perhaps this step will fix the problem. Secondly, you need to make sure that the printer is displayed and ready to use in the Device Manager on your computer. This indicates that the device is correctly installed and configured, connected to the mains. Thirdly, you need to check if the paper is jammed in the printer and if there is toner in the cartridge. If there are problems with connecting the device, paper jams or the toner in the cartridge has run out, then such problems are solved by quickly eliminating the cause of the malfunction (correcting the cable, removing the jammed paper, refilling the cartridge). If the problem is in the "Device Manager" , the computer does not

What does data science have in store for 2021?

 Data is everywhere. In an increasingly digital world, the science that brings them together and analyzes them is constantly increasing in importance. 2020 was a year that presented us with new Artificial Intelligence interfaces, the improvement of existing ones and brought up issues like LGPD and how the analysis of the information we leave on the networks is made. But what awaits us in 2021? Several factors are expected to influence the labor market.  Know more:  Managed Storage Services And one of them is on the date of arrival in the market of young native people, who already see the world with great familiarity in data analysis. As Lucy Kosturko, manager of social innovation at SAS, pointed out, these young people live in this ecosystem from the moment they eat until they go to sleep. This generation that has an understanding and tracking of data acquired in an innate way and certainly their actions will mark 2021. Faced with scenarios like this, I bring together the three trends
