United We Stand, Divided We Fall.

By Dudu Mimran | December 12, 2016September 29, 2020 by Dudu Mimran

If I had to single out an individual development that elevated the sophistication of cybercrime by order of magnitude, it would be sharing. Codesharing, vulnerabilities sharing, knowledge sharing, stolen passwords, and anything else one can think of. Attackers that once worked in silos, in essence competing, have discovered and fully embraced the power of cooperation and collaboration. I was honored to present a high-level overview on the topic of cyber collaboration a couple of weeks…

Rent my Brain and Just Leave me Alone

By Dudu Mimran | August 20, 2016September 29, 2020 by Dudu Mimran

Until AI is intelligent enough to replace humans in complex tasks there will be an interim stage, and that is the era of human brain rental. People have diverse intelligence capabilities, and many times these are not optimally exploited due to living circumstances. Other people and corporations which know how to make money many times lack the brainpower required to scale their business. Hiring more people into a company is complicated, and the efficiency level…

Right and Wrong in AI

By Dudu Mimran | August 8, 2016September 29, 2020 by Dudu Mimran

Background The DARPA Cyber Grand Challenge (CGC) 2016 competition has captured the imagination of many with its AI challenge. In a nutshell, it is a contest where seven highly capable computers compete, and a team owns each computer. Each group creates a piece of software that can autonomously identify flaws in their computer and fix them and identify flaws in the other six computers and hack them. A game inspired by the Catch The Flag…

Is Chatbots a Passing Episode or Here to Stay?

By Dudu Mimran | July 9, 2016September 29, 2020 by Dudu Mimran

Chatbots are everywhere. It feels like the early days of mobile apps where you either knew someone who is building an app or many others planning to do so. Chatbots have their magic. It?s a frictionless interface allowing you to chat with someone naturally. The main difference is that on the other side there is a machine and not a person. Still, one as old as I got to think whether it is the end…

Cyber-Evil Getting Ever More Personal

By Dudu Mimran | April 25, 2016September 29, 2020 by Dudu Mimran

Smartphones will soon become the target of choice for cyber attackers?making cyber warfare a personal matter. The emergence of mobile threats is nothing new, though until now, it has mainly been a phase of testing the waters and building an arms arsenal. Evil-doers are always on the lookout for weaknesses?the easiest to exploit and the most profitable. Now, it is mobile’s turn. We are witnessing a historic shift in focus from personal computers, the long-time…

Is It GAME OVER?

By Dudu Mimran | May 6, 2015September 29, 2020 by Dudu Mimran

Targeted attacks take many forms, though there is one common tactic most of them share: Exploitation. To achieve their goal, they need to penetrate different systems on-the-go. The way this is done is by exploiting unpatched or unknown vulnerabilities. More common forms of exploitation happen via a malicious document that exploits vulnerabilities in Adobe Reader or a malicious URL that exploits the browser in order to set a foothold inside the end-point computer. Zero-Day is…

Exploit in the Wild, Caught Red-Handed

By Dudu Mimran | April 29, 2015September 29, 2020 by Dudu Mimran

Imagine a futuristic security technology that can stop any exploit at the exact moment of exploitation?regardless of the way the exploit was built, its evasion techniques, or any mutation it might have or was possibly imagined to have. This technology is truly agnostic for any form of attack. An attack prevented with its attacker captured and caught red-handed at the exact point in time of the exploit…Sounds dreamy, no?

Time to Re-think Vulnerabilities Disclosure

By Dudu Mimran | April 14, 2015September 29, 2020 by Dudu Mimran

Public disclosure of vulnerabilities has always bothered me and I wasn’t able to put a finger on the reason until now. As a person who has been involved personally in vulnerabilities disclosure, I am highly appreciative of the contribution security researchers on awareness and it is very hard to imagine what would the world be like without disclosures. Still, the way attacks are being crafted today and their links to such disclosures got me into…

No One is Liable for My Stolen Personal Information

The main victims of any data breach are actually the people, the customers, whom their personal information has been stolen and oddly?they don?t get the deserved attention. Questions like what was the impact of the theft on me as a customer, what can I do about it?and whether I deserve some compensation are rarely dealt with publicly.

The exhibition hall was split into three sections: the booths of the established companies, the startups pavilion and the Cyber Spark arena. It was like examining an x-ray of the emerging cyber industry in Israel, where on one hand you have the grown-ups whom are the established players, the startups/sprouts seeking opportunities for growth, and an engine which generates such…

Back then, security?which was not yet referred to as cybersecurity?was one of the…

Distributed Cyber Warfare

By Dudu Mimran | March 8, 2015September 29, 2020 by Dudu Mimran

One of the core problems with cybercriminals and attackers is the lack of a clear target. Cyber attacks are digital in nature and as such, they are not tied to specific geography, organization, and or person – finding the traces to the source is non-deterministic and ambiguous. In a way, it reminds me of real-life terrorism as an effective distributed warfare model which is also difficult to mitigate. The known military doctrines always assumed a…

Taming The Security Weakest Link(s)

By Dudu Mimran | February 26, 2015September 29, 2020 by Dudu Mimran

Overview The security level of a computerized system is as good as the security level of its weakest links. If one part is secure and tightened properly and other parts are compromised, then your whole system is compromised, and the compromised ones become your weakest links. The weakest link fits well with attackers? mindset which always looks for the least resistant path to their goal. Third parties in computers present an intrinsic security risk for…

To Disclose or Not to Disclose, That is The Security Researcher Question

Microsoft and Google are?bashing each other on the zero-day exploit in Windows 8.1 that was disclosed by Google last week following a 90 days grace period.

There is a big difference between just telling the world…

Google Project Zero has debuted with the aim of solving the vulnerabilities problem by identifying zero-day vulnerabilities, notifying the company which owns the software, and giving them 90 days to solve the problem. After 90 days they publish the exploit. And they just did it to Microsoft. I remember quite a while ago when we decided at the cyber labs at Ben-Gurion University to adopt such a policy following our discovery of a vulnerability in…

Counter Attacks – Random Thoughts

The surging amount of cyber attacks against companies and their dear consequences pushes companies to the edge. Defensive measures can go only so far in terms of effectiveness, assuming they are fully deployed which is also far from being the common case. Companies are too slow to react to this new threat which is caused by a fast-paced acceleration in the level of sophistication of attackers. Today companies are at a weak point. From a…

Cutting Down North Korea’s Internet

Could be interesting to understand whether cutting down North Korea from the internet was a defensive measure due to a huge amount of ongoing attacks or was it just a preventive measure. Definitely cutting down the internet has become another weapon in the war chest of the US. The question is now: do other countries have such power of cutting down areas? The net infrastructure should be evaluated for such attack vector.

Consumers to Enterprise – The Investment Rationale Cycle

One of the main problems with Android for app developers contemplating on Android vs. iOs is the fact it is highly fragmented.
