Introducing Cloudflare's 2023 phishing threats report

After shutting down a ‘phishing-as-a-service’ operation that impacted thousands of victims in 43 countries, INTERPOL recently noted, “Cyberattacks such as phishing may be borderless and virtual in nature, but their impact on victims is real and devastating.” Business email compromise (BEC), a type of malware-less attack that tricks recipients into transferring funds — for example — has cost victims worldwide more than $50 billion, according to the FBI.

It is estimated that 90% of successful cyber attacks start with email phishing, which continues to be very lucrative for attackers. There is not much today that can be done to stop phishing attempts. However, to prevent successful attacks, it is important to understand (and proactively address) evolving phishing trends — including the ways attackers cleverly exploit intended victims’ trust in “known” email senders. To that end, this week Cloudflare published its first Phishing Threats Report.

This report explores key phishing trends and related recommendations, based on email security data from May 2022 to May 2023. During that time, Cloudflare processed approximately 13 billion emails, which included blocking approximately 250 million malicious messages from reaching customers’ inboxes. The report is also informed by a Cloudflare-commissioned survey Continue reading

Free Subscription No Longer Needed to Watch the ipSpace.net Videos

I’m publishing a link to a free ipSpace.net video several times each month, usually with a notice saying you need free subscription to watch the video. I had to put that limitation in place when I was hosting videos on AWS S3 – unlimited streaming could explode my AWS bill.

Recently I moved the video storage to Cloudflare R2. Cloudflare claims they will never charge egress fees, and as long as that’s true (and they don’t start chasing me for generating too much traffic) I see no reason to bother you with registration and login procedures – starting immediately, you can watch the free ipSpace.net videos without an ipSpace.net account.

AWS CLIv2 on OpenBSD

The AWS CLI is a tool set that lets you manage your AWS resources. The CLI comes in two versions which, at the time of this writing, are developed concurrently: version 1 and version 2.

Internally, the AWS CLIv1 and v2 are quite different. Version 2 pulls in AWS libraries--libraries which are used across the AWS SDK ecosystem--rather than reinventing the wheel when it comes to common tasks, such as talking to Amazon S3. Running AWS CLIv2 on your operating system of choice requires building and installing these common AWS libraries.

I contributed changes to s2n-tls, aws-lc, the Python runtime, some build tooling, and various other libraries. As a result, the AWS CLIv2 now builds and runs on OpenBSD.

To make installation simple, I've created an OpenBSD port for CLIv2 and its dependencies. Instructions for installing the port are below.

Hybrid mesh firewall platforms gain interest as management challenges intensify

As enterprise networks get more complex, so do the firewall deployments.There are on-premises firewalls to manage, along with firewalls that are deployed in virtual machines and firewalls deployed in containers. There are firewalls for clouds and firewalls for data centers, firewalls for network perimeters, and firewalls for distributed offices. According to Gartner, by 2026, more than 60% of organizations will have more than one type of firewall deployment."A firewall used to be a box or a chasse with multiple cards," says Omdia analyst Fernando Montenegro. "Then we had a firewall in a virtual machine. And now we have a container form factor for a firewall because customers are deploying containers. And, oh, we need firewalls-as-a-service to support SASE."To read this article in full, please click here

Hybrid workforce demands change from network ops

The pandemic forced businesses to send employees home to work, but even in recovery, the workforce trend is going strong. Some remote work measures were considered a temporary fix, and now the hybrid work reality demands IT organizations reassess how they can deliver consistent support, service, and technology to employees wherever they decide to work.“There have been a lot of conversations about return to work, but it’s not really happening,” said Shamus McGillicuddy, vice president of research at Enterprise Management Associates, during a recent webinar.To read this article in full, please click here

Hiding from history on Linux

Linux shells like bash have a convenient way of remembering commands that you type, making it easy to run them again without having to retype them. Just use the history command (which is a bash built-in) and then use an exclamation point followed by the number shown in front of the command in the history command output that you want to rerun. Alternatively, you can back up to that command by pressing the up arrow key as many times as needed to reach that command and then press return. Don’t forget, though, that you can also set up commands you are likely to use often as aliases by adding a line like this to your ~/.bashrc file so that you don’t need to search for them in your command history. Here’s an example:To read this article in full, please click here

Backblaze sees rise in hard drive failure rates

The latest quarterly report from Backblaze on hard drive reliability reveals a rise in failures among certain drives.Backblaze is a pure storage provider; cloud storage is all they do, and they dig deep into the statistics of hard drive failure and share their data with the industry. The company currently has a massive inventory of 241,297 hard disk drives of varying capacities and from various brands. (In recent quarters, Backblaze has added SSD performance to its measurements, but SSDs are still early in their deployment lifecycle, so patterns over time have yet to fully emerge.)To read this article in full, please click here

Containerlab dashboard

The GitHub sflow-rt/containerlab project contains example network topologies for the Containerlab network emulation tool that demonstrate real-time streaming telemetry in realistic data center topologies and network configurations. The examples use the same FRRouting (FRR) engine that is part of SONiC, NVIDIA Cumulus Linux, and DENT network operating systems. Containerlab can be used to experiment before deploying solutions into production. Examples include: tracing ECMP flows in leaf and spine topologies, EVPN visibility, and automated DDoS mitigation using BGP Flowspec and RTBH controls.
