netlab 1.6.4: Support for Multi-Lab Projects; More BGP Goodies

Features in netlab release 1.6.4 were driven primarily by the needs of my BGP labs project:

• bgp.session plugin (formerly known as ebgp.utils plugin) got support for BFD, passive BGP peers and remove-private-as option.
• bgp.policy plugin implements basic BGP routing policy tools, including per-neighbor weights, local preference and MED.
• You can enable external tools in user defaults and use default groups to create user- or project-wide groups in the defaults files.
• Version-specific lab topology files allow netlab to select a lab topology that is a best fit for the netlab release you’re running.

Numerous platforms already support the new BGP nerd knobs:

How Long Before AI Servers Take Over The Market?

When hyperscalers and cloud builders think about their infrastructure, they talk about megawatts and they think about the mix of serving and storage and the total capacity that is delivered in a megawatt of power. …

Setting up secure wifi

If you don’t set a password on your wifi, then not only can anyone connect, but it’s not even encrypted. This means that even when an open network gives you a captive portal, that could actually be an attacker giving you a fake portal. Even if the portal is HTTPS, because you may be connected to https://evil-fake-portal.com.

That is solved in WPA3, where even open networks become encrypted.

Of course, the attacker can just set up a fake access point, and you’ll connect, none the wiser. Even if the network has a password, the attacker only needs to know that password in order to fake it.

Before WPA3, passwords can easily be brute forced offline. A few years ago I calculated that it would cost about $70 to crack the default generated 8 character random passwords used by a popular ISP here in London, using some GPUs in Google Cloud. I’m sure it’s cheaper now.

That’s potentially years of free use of your neighbours wifi, for just the cost of a couple of months of paying for your own.

But that’s illegal, of course. This post is about protecting you against these attacks, not performing them.

Numeric operations on Linux

Linux systems provide numerous ways to work with numbers on the command line – from doing calculations to using commands that generate a range of numbers. This post details some of the more helpful commands and how they work.The expr command One of the most commonly used commands for doing calculations on Linux is expr. This command lets you use your terminal window as a calculator and to write scripts that include calculations of various types. Here are some examples:$ expr 10 + 11 + 12 33 $ expr 99 - 102 -3 $ expr 7 \* 21 147 Notice that the multiplication symbol  * in the command above requires a backslash to ensure the symbol isn’t interpreted as a wildcard.

Cyber attacks in the Israel-Hamas war

On October 7, 2023, at 03:30 GMT (06:30 AM local time), Hamas attacked Israeli cities and fired thousands of rockets toward populous locations in southern and central Israel, including Tel Aviv and Jerusalem. Air raid sirens began sounding, instructing civilians to take cover.

Approximately twelve minutes later, Cloudflare systems automatically detected and mitigated DDoS attacks that targeted websites that provide critical information and alerts to civilians on rocket attacks. The initial attack peaked at 100k requests per second (rps) and lasted ten minutes. Forty-five minutes later, a second much larger attack struck and peaked at 1M rps. It lasted six minutes. Additional smaller DDoS attacks continued hitting the websites in the next hours.

Not just DDoS attacks

Multiple Israeli websites and mobile apps have become targets of various pro-Palestinian hacktivist groups. According to Cybernews, one of those groups, AnonGhost, exploited a vulnerability in a mobile app that alerts Israeli civilians of incoming rockets, “Red Alert: Israel”. The exploit allowed them to intercept requests, expose servers and APIs, and send fake alerts to some app users, including a message that a “nuclear bomb is coming Continue reading

VPP IXP Gateway – Part 1

About this series

Ever since I first saw VPP - the Vector Packet Processor - I have been deeply impressed with its performance and versatility. For those of us who have used Cisco IOS/XR devices, like the classic ASR (aggregation service router), VPP will look and feel quite familiar as many of the approaches are shared between the two.

There’s some really fantastic features in VPP, some of which are lesser well known, and not always very well documented. In this article, I will describe a unique usecase in which I think VPP will excel, notably acting as a gateway for Internet Exchange Points.

In this first article, I’ll take a closer look at three things that would make such a gateway possible: bridge domains, MAC address filtering and traffic shaping.

Introduction

Internet Exchanges are typically L2 (ethernet) switch platforms that allow their connected members to exchange traffic amongst themselves. Not all members share physical locations with the Internet Exchange itself, for example the IXP may be at NTT Zurich, but the member may be present in Interxion Zurich. For smaller clubs, like IPng Networks, it’s not always financially feasible (or desirable) to order a dark fiber between two adjacent Continue reading

How Cloudflare mitigated yet another Okta compromise

On Wednesday, October 18, 2023, we discovered attacks on our system that we were able to trace back to Okta – threat actors were able to leverage an authentication token compromised at Okta to pivot into Cloudflare’s Okta instance. While this was a troubling security incident, our Security Incident Response Team’s (SIRT) real-time detection and prompt response enabled containment and minimized the impact to Cloudflare systems and data. We have verified that no Cloudflare customer information or systems were impacted by this event because of our rapid response. Okta has now released a public statement about this incident.

This is the second time Cloudflare has been impacted by a breach of Okta’s systems. In March 2022, we blogged about our investigation on how a breach of Okta affected Cloudflare. In that incident, we concluded that there was no access from the threat actor to any of our systems or data – Cloudflare’s use of hard keys for multi-factor authentication stopped this attack.  

The key to mitigating this week’s incident was our team’s early detection and immediate response. In fact, we contacted Okta about the breach of their systems before they had notified us. The attacker used an open Continue reading
