SOC Forum 2017: How I Learned to Stop Worrying and Love Massive Malware Attacks

Today I spoke at SOC Forum 2017 in Moscow. It was a great large-scale event about Security Operation Centers. 2,700 people registered. Lots of people in suits 😉 . And lots of my good fellows.

SOC Forum 2017 Alexander Leonov

The event was held in Radisson Royal Congress Park. There were three large halls for presentations and a huge space for exhibition/networking.

I would like to mention а stand of Positive Technologies. They have shown today their new PT Security Intelligence Portal with dashboards for executives and joint service with Solar Security for providing GosSOPKA functionality. Some stands were dedicated to Russian government Information Security initiatives: GosSOPKA, BDU FSTEC vulnerability database and FinCERT of the Central Bank of Russia.

During my presentation, I was talking how massive malware (ransomware) attacks can be useful for an organization. Quite a provocative topic, right? 😉 I meant it in the sense that all the hype around malware attack can help Information Security team to do the the following things:

  • Establish useful policies, like mandatory Windows host reboot after patch installation
  • Ban some convenient, but dangerous functionality, like smb file sharing between workstations
  • Implement useful processes, like system hardening (e.g. against mimikatz) or continuous processing of CERT (FinCERT) bulletins

Petya the Great and why *they* don’t patch vulnerabilities

I really like this. Just imagine. Quiet, routine, everyday Vulnerability Management process in organizations: scanning-patching, scanning-patching, scanning-patching… And then. Suddenly! PEEETYYA!!!

And at very same moment everything changes. People from different companies start to communicate with each other actively, reverse this new malware, share the data, write and share tools for detection and recovery. Security professional is a friend, a brother and a source of useful information for security professional. Real movement! Real community! =)

Petya ransomware

For example, my friends from Vulners.com created pretty popular gist about Petya (petrWrap, notPetya, GoldenEye) and updated in real time for several hours.

Vulners Petya gist

My former colleagues from Positive Technologies released detailed technical review of this ransomware (in Russian) few hours since the outbreak started, at 01:00 am . They also found a local kill switch, and probably were the first one. Simultaneously with Amit Serper from Cybereason.

PHDays VII: To Vulnerability Database and beyond

Last Tuesday and Wednesday, May 23-24, I attended PHDays VII conference in Moscow. I was talking there about vulnerability databases and the evolution process of vulnerability assessment tools, as far as I understand it.

To Vulnerability Database and beyond

But first of all, a few words about the conference itself. I can tell that since the last year the event got even better. I’ve seen lot of new faces. Some people I didn’t know, but they knew me by my blog and accounts in social networks. What a strange, strange time we live in! I was very pleased to see and to talk with you all, guys! 🙂

PHDays is one of the few events that truly brings all Russian community of security professionals together. I’ve seen people I have studied with in university, colleagues from the all places where I have been worked, and nearly all researchers and security practitioners that I follow. Big thanks for the organizers, Positive Technologies, for such an amazing opportunity!

It is also a truly international event. You can see speakers from all over the world. And all information is available both in Russian and English. Almost all slides are in English. Three parallel streams of reports, workshops and panel discussions were dubbed by professional simultaneous interpreters, like it is a United Nations sessions or something, recorded and broadcast live by the team of operators and directors. Final result looks really great.

Video of my presentation:

I was talking too fast and used some expressions that was hard to translate. The translator, however, did an awesome job. He is my hero! 🙂 If you didn’t understand something on video, I made a transcript bellow.

A version without translation for Russian-speakers is here.

Unfortunately gif animation is not working in the Slideshare viewer.

Today I would like to discuss vulnerability databases and how vulnerability assessment systems has been evolving. Prior to discussing vulnerability databases I need to say that any vulnerability is just a software error, a bug, that allowing hacker to do some cool things. Software developers and vendors post information about such vulnerabilities on their websites. And there are tons and tones of vendors, and websites, and software products, and vulnerabilities.

WannaCry about Vulnerability Management

Nearly all mainstream media wrote today about massive ransomware attacks around the world: 16 medical institutions in UK, strong rumours that huge companies in Russia, and even Russian Ministry of Internal Affairs suffered a damage.

At this moment Kaspersky recorded more than 45,000 attacks in 74 countries around the world, but mostly in Russia. During the attack WannaCry malware encrypts data with the extension “.WCRY” added to the filename – that’s why it is called this way.

WannaCry CryptoLocker

What I like in this WannaCry story, that it’s actually all about Vulnerability Management.
