Australian Dept. of Human Services Building Cyber Staff With New University Graduates

 (March 5, 2018)

Facing a significant shortage of qualified cybersecurity specialists, Australia's Department of Human Services (DHS) "made a conscious decision to hire straight from school and train them internally." DHS also hired people with more experience who are contracted to spend half their time as mentors to the trainees. The agency more than tripled its cybersecurity workforce in just 12 months. DHS estimates that it will know in two years if the new strategy is effective. DHS's new hiring approach was detailed in Microsoft's "Navigating the new cybersecurity threat landscape" report.


[Editor Comments]

[Murray] Sounds like normal procedure to me.  Someone hires and trains new grads.   If no one is doing it, that would account for the lack of experienced people in the market place.


[Paller]  The UK has taken this approach a step further by making sure students they hire have the aptitude and the basic technical mastery necessary for success and are ready for jobs in cybersecurity.  HMG CyberDiscovery Programme, a $25 million program that is transforming the UK cyberskills pipeline. https://www.joincyberdiscovery.com/resources


[Ullrich] Part of the skill shortage is that employers expect to hire individuals who already have all the skills they need for a given role. This may work for traditional jobs with a long history of training and recruiting. But cybersecurity roles are different. Even if you happen to find the odd candidate who actually has worked and is an expert using the exact security product you are using, chances are that this knowledge will be out of date in a couple years. It is much more effective to hire individuals who have been taught solid foundational skills and who are willing and have the ability to continue to learn.

Microsoft Reissuing Patches with Intel Firmware Fixes

(March 1 & 2, 2018)

Microsoft has begun reissuing patches that include Intel firmware fixes for the Meltdown and Spectre CPU flaws. Earlier versions of the patches caused problems for some users.


[Editor Comments]

[Neely] Test these patches before deploying, both for reliability and impact.

The SEC is Serious About Regulating Cryptocurrencies

(February 28 & March 1, 2018)

The US Securities and Exchange Commission (SEC) has signaled that it is getting serious about regulating cryptocurrencies. The SEC has issued subpoenas and information requests to financial technology (FinTech) companies that have made initial coin offerings (ICOs). The FinTech industry has by and large resisted the notion that cryptocurrencies are securities and therefore subject to federal regulation. (please note that the WSJ article is behind a paywall.)


[Editor Comments]

[Neely] No surprise here. With more companies participating in ICOs, cryptocurrency is moving to the mainstream; this is now on the regulators' radar. While lack of regulation was an appeal for cryptocurrency, malware mining and theft is driving the need for consumer protections.

Upgrade Available for Pivotal Spring Web App Platform Flaw

(March 5, 2018)

A critical flaw in the Pivotal Spring web development framework could be exploited to remotely execute arbitrary code. Users are urged to upgrade to Spring Data REST 2.5.12, 2.6.7, 3.0 RC3; Spring Boot 2.0.0.M4; and Spring Data release train Kay-RC3.


[Editor Comments]

[Ullrich] Note that the patch was released in September. I applaud the researchers at lgtm.com for delaying the more detailed release to give people some time to patch. But if you haven't patched yet: You better do so this week.

Windows Defender Can Detect FinFisher

(March 1 & 5, 2018)

Microsoft Windows Defender is now able to detect FinFisher spyware. FinFisher has proven difficult to reverse engineer because it employs "all kinds of tricks, ranging from junk instructions and 'spaghetti code' to multiple layers of virtual machines and several known and lesser-known anti-debug and defensive measures." FinFisher has typically been used by law enforcement agencies.


[Editor Comments]

[Pescatore] Great blog writeup on the forensic analysis of FinFisher but any AV software announcing it now stops "MalwareX" is like a mesh snow parka that now stops "SnowflakeX" but doesn't mention all those other snowflakes that get right through...

Facebook Adopts HSTS Preloading

(March 5, 2018)

On March 5, Facebook implemented HTTPS Strict Transport Security (HSTS) preloading. This means that if a user clicks on a link and an HTTPS-secured version of that link is available, Facebook will automatically direct the users there.


[Editor Comments]

[Neely] There are three components to HSTSa valid certificate, a redirect from HTTP to HTTPS, and the HSTS header which includes a max age setting directing the browser to not attempt HTTP connections for at least 1 year. HSTS is also designed to prevent HTTP downgrade attacks, and we all should be using it. When implementing HSTS, add the preload option last and start with shorter age settings while testing as changing data that is cached for a year can be problematic.

4G LTE Security Flaws

(March 2 & 5, 2018)

Vulnerabilities in the 4G LTE wireless telecommunications standard could be exploited to send phony emergency alert messages to mobile phones and launch at least nine other attacks. Researchers from Purdue University and the University of Iowa have published a paper describing tool they have developed to detect these security issues.


[Editor Comments]

[Neely] Some of the security in LTE depends on security by obscurity, including temporary random unique identifiers which turned out to be neither temporary or random. Expect carriers to jump on remedying that oversight.

Updated SEC Cybersecurity Guidance is Problematic

(February 26 & March 5, 2018)

Updated cybersecurity guidance from the US Securities and Exchange Commission (SEC) does not adequately address the quandary companies face when they are required to report a breach yet in some cases must not disclose the breach while law enforcement is investigating. In addition, the new guidance has been criticized for not going far enough to make sure that companies pay more attention to their cybersecurity.


[Editor Comments]

[Pescatore] The "we couldn't report the breach because of an ongoing law enforcement investigation" is a false strawman. Well over 95% of breaches that aren't reported in a timely manner where law enforcement is involved are due to the fact that the breached company didn't even notice they had a breach until notified by law enforcement! In the vast majority of incidents, there is no law enforcement involvement early enough to be any impediment to protecting customers by notifying them of the breach.

Authorities in Iceland Arrest Suspects in Bitcoin Server Thefts

(March 2, 2018)

Police in Iceland have arrested 11 people in connection with the theft of hundreds of servers along with graphics cards, processors, motherboards, and other equipment that were being used to mine cryptocurrency. The stolen machines have not been recovered. Authorities are asking ISPs, electricians, and storage units to report unusual spikes in energy consumption.     


[Editor Comments]

[Williams] Know how to get replacement hardware for your mission critical workloads in case of theft, damage, etc. Due to market demand and product scarcity, replacing the mining rigs probably isn't an option at all. This also demonstrates an interesting intersection between the digital and physical worlds, where electricians and utility records are the most likely methods to find the stolen goods.

UDP-Amplified DDoS Attacks Include Extortion

(March 2 & 5, 2018)

Some of the recent memcached amplified distributed denial of service (DDoS) attacks have been accompanied by demands for ransom paid in Monero cryptocurrency. The DDoS attacks have been the largest yet seen. An attack on GitHub last week topped out at 1.3 Tbps for eight minutes. And Arbor Networks recently reported a 1.7 Tbps attack against a service provider.


[Editor Comments]

[Ullrich] In this case, paying the ransom is absolutely useless. The extortion attempts seen so far all use the same Monero destination address for the ransom, so whoever is launching these attacks has no idea who is paying and they probably do not care as they will just continue their random attacks.
