Information BlackMatter Strikes Iowa Farmers Cooperative, Demands $5.9M Ransom
Posted by: silversurfer - Yesterday, 14:20 - Forum: Privacy & Security News - No Replies

Quote:A ransomware group believed to be the latest incarnation of the infamous DarkSide cybergang is being blamed for taking out a farmers’ cooperative online network, with extortionists demanding $5.9 million in ransom.
 
The group BlackMatter is credited for the attack on an Iowa collective of farmers called NEW Cooperative. The incident occurred over the weekend, locking up computer systems. Threat actors behind the attack are demanding a $5.9 million ransom to provide a decryptor, which will increase to $11.9 million if not paid in five days, according to reports.
 
The Iowa-based organization is a feed and grain cooperative, with 50 locations. It provides a variety of digital and software services to its network of farmers. As a result of the attack, it had to shut down its operations and also faces the threat of BlackMatter leaking stolen data if it does not pay the ransom, according to reports. This method of double extortion is now common and a hallmark of the former DarkSide group, whose members are believed to now be running the show at BlackMatter.

New Cooperative took its systems offline as a mitigation tactic, a representative told BleepingComputer, according to a published report.

Information Amazon Driver-Surveillance Cameras Roll Out, Sparking Debate
Posted by: silversurfer - Yesterday, 14:17 - Forum: Privacy & Security News - No Replies

Quote:Drivers working for Amazon Delivery Service Partners (DSPs) are increasingly under constant surveillance for safe driving, monitored by artificial intelligence which awards them a score and generates voice reminders for safe driving. That score is used to award bonuses, promotions and more.
 
Drivers who spoke to Vice’s Motherboard complained the tech is too sensitive, often wrong and making their jobs miserable — and not to mention, taking money out of their paycheck. But Amazon spokeswoman Alexandra Miller told Threatpost if the choice is between a few unhappy drivers and improved safety, it’s an easy call — safety wins.
 
Earlier this year, Amazon rolled out the pilot program for its DSPs using video surveillance and AI tech from Netradyne. The company says that so far, about half of its delivery fleet has the technology, and since the program launched it has experienced a 48-percent decrease in accidents. Also, drivers running stop signs and red lights fell by 77 percent; and distracted driving went down 75 percent.

Information Europol Breaks Open Extensive Mafia Cybercrime Ring
Posted by: silversurfer - Yesterday, 14:16 - Forum: Privacy & Security News - No Replies

Quote:International law enforcement has busted up an extensive cybercrime operation run by a gang with ties to the Italian Mafia.
 
The group allegedly used phishing attacks to defraud hundreds of victims. The suspects used various lures to convince victims (mostly Italian nationals but also Spanish, English, German and Irish targets) to wire money to bank accounts controlled by the criminal network, according to Europol.
 
“The group, using hackers specialized in latest-generation phishing and vishing attacks and in the use of social-engineering techniques, had taken possession of the home banking credentials of victims… arranging bank transfers for thousands of Euro,” according to an announcement from the Italian National Police (Polizia di Stato).
 
The gang also engaged in other types of online fraud such as SIM swapping and business email compromise (BEC), Europol said. In all cases, the attackers laundered the money through a wide network of money mules and shell companies.
 
“The stolen sums were later recycled through the purchase of cryptocurrency or reinvested in further criminal activities, such as prostitution, drug production and trafficking, and arms trafficking,” according to the Polizia di Stato.

Information Payment API Bungling Exposes Millions of Users’ Payment Data
Posted by: silversurfer - Yesterday, 14:14 - Forum: Privacy & Security News - No Replies

Quote:App developers have once again been accused of having butterfingers when it comes to API keys, leaving millions of mobile app users at risk of exposing their personal and payment data.
 
CloudSEK, maker of artificial intelligence- (AI-) enabled digital threat protection, reported last week that the mobile ecosystem is reeking with hard-coded API keys: Keys that should never be exposed in endpoint apps.
 
Misconfigured APIs make any app risky, but when you’re talking about financial apps, it’s about handing ne’er-do-wells the power to turn victims’ pockets inside-out.
 
“While the rampant exposure of API keys is hazardous for any app, it is especially critical when it comes to apps that handle payment information such as bank details, credit card information and UPI transactions, in addition to user [personally identifiable information, or PII],” according to CloudSEK’s writeup.
 
APIs – application programming interfaces – are the veins and arteries of the mobile ecosystem, enabling apps to communicate with multiple sources and to move data in and out of those apps. It’s an “integral” part of how an app works, CloudSEK said, which means that app developers need to handle them with kid gloves in order to avoid leaking customer data: “Any systematic mishandling of API keys among app developers can cause threat to the app’s business,” researchers maintained.

Spotlight on Security: AV-Comparatives offers advice on choosing Android AV apps

This blogpost offers users assistance in selecting a suitable antivirus product for the Android platform. Eight of this year’s products qualified for certification, by reaching a malware protection rate of at least 99%, with less than 10 false positives, and a battery drain of less than 8%. In the Android 2021 test report, AV-Comparatives gives an overview of the general security-related components, which are summarised in the additional feature list. 
 
Anti Malware: includes a function to scan against malicious apps 

This feature is the only one required for AV-Comparatives‘ certification. When using and storing apps and files on external storage (e.g. SD card), it is recommended to make sure that the AV product supports scanning of external media. It should also be noted that with some AV products, scanning requires an active Internet connection. AV products may also support stalkerware detection. More information on stalkerware detection on Android can be found here (PDF).

Anti-Theft: includes remote functions in case the smartphone is lost or stolen 

An anti-theft function with location tracking is already built into current versions of the Android operating system, but is also additionally offered by AV products.

The anti-theft function makes it possible to reset the smartphone. The alarm function, for locating the smartphone or deterring a thief, should ideally only be controllable remotely. Optional is the activation of the front camera, and the automatic locking of the smartphone when the SIM card is changed. 

Safe Browsing: includes a web-filter function to block dangerous websites 

The anti-malware and anti-phishing protection features are often only implemented for certain browsers. Each AV product has its preferences as to which browser apps are supported. 

App Audit: contains functions for controlling installed apps 

The app audit feature, which provides information about permissions, mobile data usage, usage time, battery consumption and memory usage of individual apps, can be easier to use in AV products than in the operating system itself. 

App Lock: contains a function to prevent unauthorised access to installed apps 

An app-lock function for directly locking apps is helpful to protect sensitive app content or system settings from unauthorised access. 

The right AV product for each person’s own smartphone should reflect the user’s own demands and technical requirements. If these are met, a trial version can often be used to test the product before purchase. Independent tests by AV-Comparatives provide useful guidance for selecting certified products.

Lightbulb Antivirus won’t let you run a program? Here’s what to do
Posted by: harlan4096 - Yesterday, 07:19 - Forum: Kaspersky Security Blog - No Replies

Here’s how to open a program if your antivirus app blocks it.

The purpose of any security solution is to protect the system and inform users about threats. But what if your antivirus utility flags a harmless program as malware, or sounds the alarm during scanning, seemingly for no reason? There’s a name for that: false positive.

As independent tests show, our solutions rarely cry wolf, but sometimes caution does prevail. If that happens to you, don’t disable protection — it’ll only put your computer at risk. Instead, designate the app as trusted or add it to the exclusions list. If you’re using a Kaspersky solution for home users, here’s what you should know.

What’s the difference between trusted applications and adding programs to the exclusions list

We want our programs to be easy to use. Therefore, the process for configuring exclusions is the same across our most popular solutions — Kaspersky Internet Security, Kaspersky Total Security, and Kaspersky Security Cloud. But before proceeding to our detailed guide, let’s shed some light on what it is you are about to do.

Modern security solutions employ a comprehensive approach to protection, not only checking for malicious items in program code by scanning programs before they run, but also monitoring installed programs for suspicious activity.

The reason for such additional checks is that cybercriminals, trying to bypass protection, sometimes begin an attack with otherwise completely harmless apps that later download more dangerous programs onto victims’ computers. Some also create malware that lies low in the system for a long time before wreaking havoc.

That’s why our developers separated the settings into two categories:
  • To prevent the antivirus app from blocking a program when you’re trying to run it, make the blocked program a trusted application;
  • To stop the antivirus app from flagging a program during a regular scan, add it as an exclusion.
Now, here’s a detailed look at how and where to configure both options in Kaspersky Internet Security, Kaspersky Total Security, and Kaspersky Security Cloud.

What to do if the antivirus app blocks a program

As a rule, antivirus apps prevent other programs from starting if they see potentially dangerous behavior. If you’re completely sure an app is safe, use exclusions settings to add it to the trusted list:
  • Open Kaspersky Internet Security’s (or Kaspersky Security Cloud’s) settings;
  • Select Threats and Exclusions;
  • Scroll down and click Specify trusted applications;
  • Specify the path to the program you want to run;
  • Select which program actions the security solution should ignore.
The general rule here is simple: the fewer the check marks, the better. We recommend experimenting with enabling and disabling the following three:
  • Do not scan files before opening,
  • Do not monitor application activity,
  • Do not scan encrypted traffic.
Well-behaved applications don’t need to interact with the solution interface, so don’t allow it.

What to do if the antivirus app flags a program during a scan

If a program prompts questions from the antivirus during scanning, or you added it to the trusted list but that didn’t help, you can try creating a scan exclusion. Here’s how to do that:
  • Open Kaspersky Internet Security’s (or Kaspersky Security Cloud’s) settings;
  • Select Threats and Exclusions;
  • Scroll down and click Manage exclusions;
  • In the window that opens, click Add;
  • Click Browse…;
  • Select the file you want to add as an exclusion;
  • Select the components you want ignored during scanning. Start by checking Scan and File Anti-Virus. If that doesn’t help, experiment with the other checkboxes, but don’t select all of them at once.
Conclusion

Now you know how to customize your antivirus utility so it won’t interfere with your work, but keep in mind that its purpose is to protect your computer. Don’t go wild and overuse the exclusions list or you might let a genuine threat slip through.

Information AMD's EPYC CPUs Push Netflix Server Bandwidth To 400 Gbps

It's all about the (EPYC) bandwidth.

Netflix has been serving up to 200 Gbps of TLS-encrypted video from a single server since 2020. Nonetheless, the company aims to double the bandwidth to 400 Gbps. During his presentation at the EuroBSD 2021 conference (via HardwareLuxx), Andrew Gallatin, Senior Software Engineer at Netflix, detailed the challenges of pushing the bandwidth envelope on its FreeBSD-based servers.

Netflix turned to AMD's EPYC Rome processors to achieve its goal. The company equipped its server with the EPYC 7502P, which wields 32 Zen 2 cores with a 2.5 GHz base clock and 3.35 GHz boost clock. More importantly, the 32-core beast offers up to 128 PCIe 4.0 lanes, good for about 250 GBps of bandwidth or around 2 Tbps in networking units. Netflix paired the EPYC 7502P with 256GB of DDR4-3200 memory, with a total memory bandwidth of up to 150 GBps, or 1.2 Tbps in networking units.

For storage, Netflix's AMD-powered server utilizes 18 Western Digital WD SN720 2TB NVMe SSDs. It's also equipped with a pair of Nvidia's Mellanox ConnectX-6 Dx network adapters that communicate through a PCIe 4.0 x16 interface. Initially, Netflix was only getting 240 Gbps out of the server, primarily due to the limitation on the memory.

Netflix experimented with different NUMA (Non Uniform Memory Architecture) configurations to maximize the bandwidth. AMD's EPYC processors support different NUMA nodes per socket, which can either be 1, 2 or 4. Naturally, the processor dictates which modes are available or not. The EPYC 7502P, which is the SKU used in Netflix's server, supports all three NUMA modes. According to Gallatin's slide, a single NUMA node configuration delivers up to 240 Gbps, while a setup with four NUMA nodes bumps the value up to 280 Gbps.

In an attempt to optimize the performance and avoid hardware bottlenecks, Netflix tested offloading the TLS encryption to the Mellanox ConnectX-6 Dx, instead of the EPYC 7502P. With a bit of tinkering with the software and some firmware updates, Netflix managed to squeeze 190 Gbps per Mellanox ConnectX-6 Dx adapter or 380 Gbps with two network adapters. The encryption no longer passes through the processor, so it helps free up resources and cuts memory bandwidth by half. The results showed 50% processor utilization, with four NUMA nodes and around 60% without NUMA.

Nvidia released updated Game Ready and Studio drivers for the final version of Microsoft's Windows 11 operating system today. The company did release its first Windows 11 ready drivers back in July, but the drivers released today are designed for the final version of Windows 11, which Microsoft plans to release on October 5, 2021.

Nvidia customers who plan on upgrading their devices to Windows 11 the moment the new operating system is released, or purchasing a new gaming PC or laptop in the first week of general availability, can point their browsers to the official GeForce Game Ready driver download page or the Nvidia Studio driver download page to download the latest drivers to the system for installation.

Windows 11 includes several new gaming related features. Three core features are DirectX 12 Ultimate, Auto HDR and DirectStorage.

Auto HDR is designed to bring High Dynamic Range to games that don't support it. It requires compatible hardware, a monitor with HDR support, and a simple flip of a preference to enable the feature on Windows 11.

Windows 11 users find the setting under Settings > System > Display > Windows HD Color Setting (link). Use HDR needs to be enabled on the page that opens, and Auto HDR as well.

DirectStorage is another new feature, albeit not exclusive to Windows 11 as Microsoft's Windows 10 operating system supports the technology as well. It requires compatible hardware as well, a fast NVMe SSD to be precise on the Windows PC, and games that support the new API. Microsoft promises faster loading times of games and and improved gaming experience.

DirectX 12 Ultimate finally "codifies several RTX graphics rendering innovations such as Raytracing, Variable Rate Shading, Sampler Feedback, and Mesh Shaders to help developers make bigger, better worlds with faster performance" according to Nvidia.

Nvidia Studio customers get a new driver and access to new features on Windows 11 as well. Nvidia lists the following three specifically:
 
Quote:Faster NVIDIA Broadcast Performance: NVIDIA Broadcast is the industry’s leading video and audio enhancement app, using the power of AI and our GPU’s Tensor Cores to make audio clearer, eliminate background noise, and improve video quality. In Windows 11, GPU-accelerated hardware scheduling receives numerous improvements and is enabled by default, enabling users to use NVIDIA Broadcast while they livestream and run a game or 3D app seamlessly.

Windows Enhance Audio: A new Sound panel enables Windows 11 users to improve and enhance the audio coming out of their speakers and headphones, making dialog clearer.

Integrated Microsoft Teams: Chat, call and conference via Microsoft Teams, which is now integrated into the taskbar, providing a faster way to connect to colleagues, friends, and family. And with our Windows 11 drivers, GPU acceleration is fully supported, and via the Teams options you can route your audio and video via NVIDIA Broadcast to enhance calls and video conferences.

You can read the official announcement on the Nvidia blog.

Now You: do you plan to upgrade to Windows 11?
