28/9/19: Evidence of Systemic Risk from Major Cybersecurity Breaches

In our post for Columbia Law School's CLS Blue Sky Blog, myself and Shaen Corbet explain in non-technical terms our ground-breaking findings on systemic nature of cybersecurity risks in financial markets:

• Published paper: https://www.sciencedirect.com/science/article/pii/S1057521919300274.

Our study is the first in the literature showing evidence of systemic contagion from cyber attacks on one company to other companies and stock exchanges.

Based on these findings, we have a chapter forthcoming in an academic volume on the future of regulation, proposing a novel mechanism for regulatory detection, monitoring and enforcement of cybersecurity risks. We will post this chapter when it goes to print, so stay tuned.

20/9/19: New paper: Systematic risk contagion from cyber events

Our new paper, "What the hack: Systematic risk contagion from cyber events" is now available at International Review of Financial Analysis in pre-print version here: https://www.sciencedirect.com/science/article/pii/S1057521919300274.

Highlights include:

• We examine the impact of cybercrime and hacking events on equity market volatility across publicly traded corporations.
• The volatility generated due to cybercrime events is shown to be dependent on the number of clients exposed.
• Significantly large volatility effects are presented for companies who find themselves exposed to hacking events.
• Corporations with large data breaches are punished substantially in the form of stock market volatility and significantly reduced abnormal stock returns.
• Companies with lower levels of market capitalisation are found to be most susceptible to share price reductions.
• Minor data breaches appear to be relatively unpunished by the stock market.

19/4/18: Geopolitical Risk: Who Cares?..

Geo-political risks, geo-shmalitical risks... who cares... not the markets...

None of the geopolitical risks registered on S&P 500 companies reporting radar according to Factset in 1Q 2018 https://insight.factset.com/more-than-half-of-sp-500-companies-citing-positive-impact-from-fx-on-q1-earnings-calls.  This is not very surprising as majority of earnings for 1Q accumulated before any spikes in these, and as "Tariffs" category probably absorbed the 'China' effect. Notably, however, earnings were impacted adversely by trade conflict and cyber risks (total of 3/25 companies impacted).

15/4/17: Swift & Digital Money: Cybersecurity Questions

Swift, the interbank clearance system, has been the Constantinople of the financial world's fortresses for some time now. Last year, writing in the International Banker (see link here), I referenced one cybersecurity incident that involved Swift-linked banks, and came close to Swift itself, although it did not breach Swift own systems. The response from Swift was prompt, pointing out that there has never been a cybersecurity breach at Swift.

Well, it appears that the fortress is no more. Latest reports suggest that NSA (a state actor in cybersecurity world) has successfully breached Swift firewalls. Details are here:
http://www.reuters.com/article/us-usa-cyber-swift-idUSKBN17H0NX.

From financial services and economy perspective, this is huge. Take a macro view: for years we have been told that cash and physical gold and silver are not safe. And for years this argument has been juxtaposed by the alleged 'safety' of digital money (not the Bitcoin and other cryptos, which the Governments loath and are keen on declaring 'unsafe', but state-run Central-Banks-operated digital money). The very notion of e-finance or digital finance rests on the basic tenet of infallibility of Swift. That infallibility is now gone. Welcome to the brave new world where the Governments promise you safe digital money in exchange for privacy and liquidity, while delivering a holes-ridden dingy of a system that can and will be fully compromised by the various states' actors and private hackers.

Come here, doggie, doggie! Have a treat...

9/4/17: JTCI Article on Cybercrime & Financial Markets Contagion

Our paper on cybersecurity risks spillovers across financial markets was published in the JTCI: http://www.terrorismcyberinsurance.com/. You can access full paper here: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2892842.

24/2/17: Cybersecurity Threats: Business Survey

An interesting insight via https://www.bloomberg.com/politics/articles/2017-02-21/threat-of-cyber-attack-is-biggest-fear-for-businesses-survey on the rising importance of the cyber-security risks and changing business perceptions of the risk. Goes handily with our findings here: http://trueeconomics.blogspot.com/2017/01/23117-regulating-for-cybercrime-hacking.html.

2/2/17: FactSet on Five 'Notable' 2016 Corporate Data Breaches

In our recent working paper on the systemic effects of cyber risks expressed via financial markets, we have shown the first empirical evidence of systemic (cross exchanges and cross companies) contagion from cyber risks to share prices of the world’s largest corporates, starting with 2014. You can read the full paper here: http://trueeconomics.blogspot.com/2017/01/23117-regulating-for-cybercrime-hacking.html.

Some new evidence on the effects of cyber crime on corporate performance is now also presented in a recent FactSet analysis here.

In this article, FactSet look at the corporate performance effects arising from five “notable” 2016 data breaches, specifically focusing on the stock performance. The methodology in this analysis, unfortunately, is weak and does not lend itself to establishing any specific hypotheses, including those claimed.

Still, an interesting collection of factoids and illustrations of the shorter term impacts (or lags in such).

24/10/16: Hacktivism on the rise? Welcome to the well-predicted future

Given a rising prevalence and impact of the cyber attacks in recent weeks, here are some slides from my February 2016 course notes on ERM with warnings about the same back at the end 2015 - start of 2016:
