I’ve been hacked

This week-end, our server ( VPS @OVH ) has been hacked ( brute force root login ).
I noticed that I was unable to log in through ssh as usual ( using RSA or ED25519 keys ) but need a password.

After successfully logging in, I found out that my authorized_keys file has been change with only one RSA key ( all others have been overwritten ) having the comment mdrfckr.

After a little Googling, I find the following article : Outlaw is Back, a New Crypto-Botnet…

Even if my version was not exactly identical, I did get me on the right path to clean it :

  1. Erased the authorized_keys file
  2. Killed the rsync process
  3. Looked at the crontab for user root ( crontab -l ) – get a bunch of stuff :
    1. 1 1 */2 * * /root/.configrc/a/upd>/dev/null 2>&1
      @reboot /root/.configrc/a/upd>/dev/null 2>&1
      5 8 * * 0 /root/.configrc/b/sync>/dev/null 2>&1
      @reboot /root/.configrc/b/sync>/dev/null 2>&1
      0 0 */3 * * /tmp/.X25-unix/.rsync/c/aptitude>/dev/null 2>&1
  4. Deleted the crontab for user root ( crontab -d ). (As you can see, on reboot it will reinstall itself otherwise )
  5. Deleted the directory : rm -fR /root/.configrc and anything in /tmp that seems suspicious.
  6. Find out through top that a process was grabbing 99% of the CPU ( mine was named kswapd0 )
  7. killed this process
  8. did a find / -name kswapd0 to find where this code was : it was not in /.rsync as in the article but in /root/.configrc so  already cleaned ( step 5 )
  9. reboot the server.
  10. Everything seems OK == according to the link above, this hack is just a crypto bot so I didn’t bother to re install the whole server even it is a best practices

Hopes it will help somebody somewhere 😉

Engine Oil, what a pollution !


A sea of soil – “Une mer d’huile”

Even without being a sailor, everyone knows the expression “a sea of oil”: One thus characterizes the surface of the water of a sea, a lake or a pond which is perfectly flat, smooth as a mirror, because nothing disturbs its surface. This pictorial expression comes in fact from a very concrete observation known since the dawn of time by all the sailors of the world: The oil calms the sea.

An efficient solution

We are extremely proud to have been awarded the #efficientSolution label from the Solar Impulse foundation. This is a welcome acknowledgment of our vision and pragmatic approach, demonstrating that it is possible to provide an economically interesting response to an urgent environmental challenge .

nitiFilter®, un filtre qui a reçu le label Efficient Solution de la fondation Solar Impulse

nitiFilter®, the future of filtration

the nitiFilter® is the present and the future of engine oil filtration : offering a permanent and maintenance-free oil filter that allows drain intervals to be spaced out is unrelenting – we simply can no longer afford to waste our resources and pollute without an afterthought.

There is a need : lubricate the hundreds of millions engines around the world

And three evidences that impose themselves on society:

  • Earth resources are limited.
  • The environment is in danger.
  • Service outweighs possession.

The staggering cost of a drain

Lubricating means using oil in astronomical quantities (almost 300 000 000L per year in France alone) AND using mountains of oil filters (probably more than 30 000 000 per year) to maintain oil as clean as possible in the engines.

Bad luck, these worn filters are contaminated in depth so are not recyclable: in the best case they are burnt, especially in cement plants. Sold as low cost fuel, they supersede clean energy.

As to the oil, it is not better: even clean it is dirty! The ancestral expression “a sea of oil” comes directly from its frightening capacity to cover huge surfaces – 1L of oil spreads over 1km2 of water!

a big challenge

Our challenge is therefore to provide a solution that avoids generating mountains of non-recyclable waste, ie replace the disposable filters by our permanent filter , and drastically limit oil consumption , ie to space drains intervals (*)

And for a challenge, it’s a hell of a it: Solar Impulse evaluation indicates a relatively modest economic impact. We totally agree with this assessment – given our marketing difficulties, it would be very pretentious and naive to say the opposite. We are clearly facing a closed market where the various actors (car and engine makers, repairers) are hiding behind various tricks, which range from delirious piece diversity (and without any technical justification ..) to the sacrosanct guarantee even when it does not apply.

However, we continue to argue that disposable and non-recyclable solutions are an aberration and that basically nothing limits the use of nitiFilter® to intensive conditions : our product simply is a smarter and more efficient answer to the requirement of oil filtration function to maintain optimum engine lubrication. It is therefore inexorable that permanent sustainable filtration will prevail on the market … this solution will happen anyway.

In addition, we are confident that the automotive industry will break out of its current schizophrenia , which is to cling to its old model of selling parts and services , while systematizing flat-rate offer . They will therefore necessarily switch to sustainable solutions to avoid having to do so unnecessary work. On the other hand, current and future (r) evolutions of mobility tend to focus on the availability (mobility as a service) for which it is interesting to improve the usage times by limiting outages and maintenance . This last point is obviously critical for all professionals who have a sustained use of their equipment (tractors, construction equipment, trucks, buses, dumpsters, sweepers, generator)

In our current market conditions (modest volume), and without even accounting for all direct and indirect costs of an oil change , the nitiFilter® has a payback of around three oil changes. So it’s a cost effective solution for anyone who moves from a short-term mindset to a long-term management (TCO management for example). Here too we are at a tipping point and are therefore convinced that the future for systems such as ours will be fruitful.

XFP is making its COP21 commitment through its revolutionary oil filter: the nitiFilter®

filtre nitifilter®

Worldwide oil consumption stands today at almost 20 billion liters. Even in the best-case scenario, 20% of used oil is released into nature, polluting the equivalent of 8 times the surface of the earth. The time has come to raise awareness of this problem, which has been ignored for to long, and to stop such useless waste.

As part of the COP21 conference, XFP is proud to present a concrete solution that can be rolled out immediately: the nitiFilter®. This revolutionary product allows the driver to consume 10 times less motor oil, and to thereby reduce CO2 emissions by a factor of 10, i.e. by 90%. Read more

NitiFilter® carbon footprint: emits less than a standard filter after the second oil change

Against the backdrop of climate issues, which have become more and more important, and at the same time as the COP21 world climate conference, we have decided to study and promote our nitiFilter® automotive filtration solution’s comparable advantage when it comes to reducing greenhouse gas emissions. It’s important to remember that in France, the transportation sector is responsible for a third of total final energy consumption (second only to the construction sector) as well as for almost 30% of greenhouse gas emissions, 95% of which come from road transportation alone. Reducing greenhouse gas emissions in this sector is therefore an absolute priority. How is the nitiFilter® a solution? What is it’s carbon impact compared to a standard filter? More reliable than a traditional oil filter, it is also greener, and its carbon footprint shows that it dramatically reduces carbon emissions.  Read more

Why is the nitiFilter® more reliable than a standard filter?

Have you ever asked yourself if your oil filter is reliable? I would guess you haven’t… But oil quality depends on the quality of the filter!

Oil filters remove contaminants from the oil before they can damage engine components. Standard filters are made from paper impregnated with phenolic resin. The nitiFilter® is made from high-quality aluminum, with a stainless steel filtration medium. But that’s not the only difference between the two. So, what makes the nitiFilter® more reliable than the paper filters you can buy for €10 from any corner mechanic? Learn more from the rest of this article. Read more

Oil filter comparison: should I chose a standard filter or a lifetime filter?

Every good driver knows how important lubrication is to their vehicle’s lifespan and proper functioning. Oil can only do its work correctly if it has been properly filtered. That’s what an oil filter does! The oil filter is responsible for removing the pollutants that build up in the oil as the engine runs. Standard “paper” filters (Purflux etc.), lifetime filters, cleanable filters, green filters… there are so many choices! But what are the differences between all of these kinds of filters, and how is the nitiFilter different from the other lifetime filters already on the market? Here is a comparison of the oil filters available on the market. Read more
