You will, no doubt, have seen some of the horrific coverage of violence used against protesters this week that is indicative of what is suffered by many every week. You may feel detached or removed from events however the issues are systemic and pervasive even in a ‘modern’ field like cyber security. Whitelist/blacklists. Master/slave. The language we use is a powerful thing and it is an area where you can make a change. Use allow lists and block lists (instead of whitelists and blacklists), and primary and secondary (instead of master/slave). Be the change you want to see in the world. #BlackLivesMatter.
REvil launches auction site for ransomware files
The Maze ransomware group started releasing copies of files that their ransomware had encrypted at the end of 2019. That effectively turned ransomware attacks, that previously only impacted integrity and availability, into data breaches impacting confidentiality too. Thirteen groups now adopt the tactics, designed to put pressure on organisations to pay up.
This week the REvil (aka Sodinokibi) group took things a step further and added eBay like auction functionality to their site on the dark web. Previously the site had hosted samples and snippets of data to allow victims to confirm the authenticity of the request. If they didn’t pay, then copies of the data were released in full for anyone to download.
Now, rather than giving the information away for free if the victim doesn’t pay, the group are monetising the data and allowing people can bid on it.
Listings have a start price - in the case of a Canadian agricultural firm $50,000 - and a ‘Blitz,’ or buy it now, price double the starting price. To make a bid you must deposit 10% of the starting price in an apparent move to discourage time-wasters.
Ransomware has seen a shift over the last 12 months from automated ‘worm’ like infections that self-propagate, to manual operations that make use of compromised credentials and use the organisations own IT administration tools to deploy the malware.
Meanwhile, the Maze group has joined forces with ‘LockBit’ and another party to form an ‘extortion cartel’ pooling resources and infrastructure. The group are quoted in BleepingComputer as saying that “this cooperation [will lead the way] to mutual beneficial outcome, for both actor groups.”
Both developments indicate how bullish cybercriminals are feeling, while many businesses are struggling with the impact of the global Coronavirus pandemic. Making sure that multi-factor authentication is enabled on external accounts, and patching remote access products are two steps organisations can take to make themselves a more challenging target.
67% of users did not change their passwords after receiving a breach notification, of those who changed it… 42% changed it to a stronger password, according to Bhagavatula et. al ieee-security.org (PDF)
37% increase in mobile phishing attacks between end of 2019 and start of 2020, according to Lookout zdnet.com Smartphones and mobile device management solutions (vol. 3, iss. 18) are increasingly being targeted for onward access into organisations.
The best defense is a good offense, the old adage goes… “[Homeland Security’s] NCCIC, which is supposed to be the ‘Nation’s flagship cyber defense, incident response, and operational integration center,’ gets just one dollar for every 10 that goes to military offensive and defensive operations.”
“[DoD’s] cyber operations budget is higher than the budgets for the CISA, the FBI and the Department of Justice’s National Security Division combined ($3.7 billion compared to $2.21 billion)” lawfareblog.com
59% think that cyber risk assessment is more useful than cyber maturity assessment, according to respondents of my poll on linkedin.com

Inside a business email compromise scam
A plea agreement in the case of a fraudster is a good read into how scammers carry out Business Email Compromise (BEC), or ‘CEO impersonation’ frauds. Details of the how a construction firm and electrical appliance manufacturer Electrolux were tricked out of $500,000 also detail the ‘back office’ work of establishing bank accounts to receive funds, and attempts to cash-out the proceeds of crime. Over 50% of cyber losses reported to the FBI’s Internet Crime Complaint centre in 2019 stemmed from BEC schemes (vol. 3, iss. 7). These losses are typically 33x higher than data breaches and 17x higher than ransomware. Professional service firms that advise or process large financial transactions have been targeted in the past: a scheme last year targeted property conveyancers in Australia and a breach this week at the Chartered Professional Accountants of Canada (CPA) could provide useful details to embellish frauds in Canada. theregister.com, bleepingcomputer.com
Cyber attacks between Israel and Iran
An attack to increase the chlorine levels in water suppliers and another to disrupt a major port are cited in this report in the FT. They are the latest tit-for-tat hostilities between Israel and Iran that have been going on for over forty years. The idea of a military cyber attack can still seem far-fetched and this stuck out for me as a reminder as to how they are already firmly established part of military and diplomatic action. Work at the United Nations continues on establishing International ‘cyber-norms’ though is split between proposals from Russia and the U.S. Ominously the piece quotes the head of Israel’s National Cyber Directorate as saying ‘cyber winter is coming.’ ft.com
Penny for your thoughts…
Checking finances can be a daunting task, but for 8,000 customers of Australia’s Commonwealth Bank it was made worse by receiving disturbing messages in their transaction descriptions. The investigation spanned three months and found multiple low-value deposits using the 18 characters as a messaging service. Some were lighthearted jokes, whilst others were ‘clear references to domestic violence.’ It’s important to consider how platforms can be abused to cause harm when creating digital services. theregister.co.uk

Breach report email wipes IT ticket system
The logo for the popular data breach notification site Have I Been Pwnd? features some SQL injection characters, as a nod to early ways in which database are often tricked into giving up customer account details. A bug in the GLPi ticket system caused the string to be rendered and executed, wiping the contents of tickets for one company after they received a breach notification from the HIBP service. Turns out the issue had already been fixed and is another lesson in why it’s important to keep your software up to date :-) theregister.com
