European Union member states have drafted a diplomatic document which states serious cyber-attacks by a foreign nation could be construed as an act of war.
The document developed as a deterrent to provocations by nation states like Russia and North Korea, will declare that member states may respond to online attacks with conventional weapons “in the gravest circumstances.”
This framework on a joint EU diplomatic response to malicious cyber activities would seem to raise the stakes significantly on state-sponsored attacks, especially those focused on critical infrastructure.
UK security minister Ben Wallace claimed last week that the UK government is “as sure as possible” that North Korea was behind the WannaCry ransomware attacks in May that crippled over a third of NHS England, forcing the cancellation of thousands of operations and appointments.
The problem is that definitive attribution in cyberspace is very difficult, making the framework appear largely symbolic.
It brings the EU in line with NATO policy in the past, establishing cyber as a legitimate military domain, meaning an online attack could theoretically trigger Article 5, the part of its treaty related to collective defense, which states that an attack on one member is an attack on all 29 allies.
McAfee chief scientist, Raj Samani, claimed the move was unsurprising considering WannaCry and the likely state-backed attacks on French and German elections.
“While it is important to define cyber-attacks that are used for espionage or disruption as they would be when committed by physical actors, the greatest challenge that countries have will be in identifying and proving that the malicious actors that caused the cyber-attack have direct links to governmental organizations – something that these groups will be even more keen to conceal going forward,” he added.”
I’m expecting the USA to follow with a similar statement, to function as an additional deterrent against the recent spate of Russian and North Korean incursions.
The vast majority of Russia’s attacks start with social engineering and spear phishing attacks. However, current investigations show that they also have been running paid propaganda campaigns through Facebook.

2018 Is Likely to Be a Worse Year for Ransomware Than 2017
Sophos released their 2018 malware forecast this week. Their predictions would make any IT Pro concerned, link to a PDF of their report below. Read on for your executive summary.
Ransomware Mutations Running Amok
You have seen a lot in this blog this year about the WannaCry and NotPetya ransomware strains. Both attacks exploited the EternalBlue Windows SMB vulnerability, and both did not have workable decryption mechanisms for the few organizations desperate enough to try to pay the ransom.
Both incidents make one thing clear: WannaCry and NotPetya appear to be the work of military cyber warfare divisions. Their authors aren’t script kiddies, but professional Dev teams using sophisticated techniques. Nation states are fighting a cold cyber war, and both commercial and non-profit organizations are the collateral damage worldwide.
RaaS Is for Newbie Cyber Crims
There is an area where amateur cyber “crims” do come in, and that’s Ransomware as a Service, aka RaaS. Newbies without l33t skills simply buy the code on the dark web including easy how-to videos.
Sophos says that RaaS is growing in popularity on the Dark Web, and this year’s Cerber ransomware is their example of a worrisome trend. Here’s some of what it says in the report that specifically pertains to RaaS:
“Ransomware is big business on the Dark Web. Its creators realized they could make more money not just by extorting currency from their victims, but by selling kits buyers could use to make and distribute their own. We’ve seen a number of different services and pricing models in the past year, and expect to see many more in 2018.
One of the biggest examples, as mentioned above, is Cerber. Other examples include Satan, malicious software that once opened in a Windows system, encrypts all the files and demands a ransom for the decryption tools, and Philadelphia. The latter was notable for its marketing technique, which included a slick YouTube video advertisement on the open web.”
New “Marketing” Techniques
Sophos reports on an additional ransomware trend they found in a malware strain called Spora. Instead of demanding one ransom to decrypt an entire encrypted drive or partition, some ransomware offers victims multiple options. The options seen in Spora are:
- Decrypt two files for nothing
- Decrypt a selection of files for 30.00 dollars
- Have the ransomware itself removed for 20.00 dollars
- Buy what they call immunity for 50.00 dollars
- Get everything on the computer restored for 120.00 dollars
Ransomware Is Now Targeting Non-Win OSen
September 2013 was when CryptoLocker reared its ugly head as the first weapons-grade ransomware that exclusively targeted Windows, which remains Target No. 1.
But Sophos notices a trend of ransomware targeting non-Windows operating systems. I would not be surprised if in 2018 a worldwide MacOS or Linux distro ransomware pandemic broke out.
Ransomware is also growing rapidly on Android. Sophos reported that the prevalence of Android ransomware has grown almost every month in 2017; 30.4% of the Android malware researched in September 2017 by Sophos was ransomware, and they expect that 45% of all Android malware in October was ransomware.
One of the biggest Android ransomware stories broke this October: DoubleLocker. Looks like Android ransomware is going to be a bigger problem in 2018.
Healthcare Continues to Be a Target.
Many cyber criminals are specifically targeting the healthcare industry. Sophos states this trend started in 2016. Healthcare is the single most targeted industry because they are the victims who are most likely to pay ransoms. The Sophos report shows that critical infrastructure, education and small businesses also are often targeted for ransomware attacks, as they’re more likely to pay up as well.
Between April 1st and October 3rd, Sophos notes that the top four countries for ransomware victims are the United States (17.2%), Great Britain (11.1%), Belgium (8.6%), and Singapore (6.5%.) And of course neither Ukraine or Russia even show up in the Top 16, because that’s where these organized cyber crime gangs are, and they know that FSB (KGB) swat teams will knock down their doors if they target these countries.
