Updates to Cryptocurrency/Crypto-mining News and Resources
John Leyden for The Register: Criminal mastermind injects malicious script into Ethereum tracker. Their message? ‘1337’ – “The Etherscan incident could have been far worse. Rather than a cheeky pop-up, a more mendacious mind might just have easily used the same flaw to run a crypto-mining scam.”
SecureList (Kaspersky): A mining multitool – “Symbiosis of PowerShell and EternalBlue for cryptocurrency mining… The creators of PowerGhost … started using fileless techniques to establish the illegal miner within the victim system. It appears the growing popularity and rates of cryptocurrencies have convinced the bad guys of the need to invest in new mining techniques – as our data demonstrates, miners are gradually replacing ransomware Trojans.”
Graham Cluley: Mind your company’s old Twitter accounts, rather than allowing them to be hijacked by hackers – “DEFUNCT FOX TV SHOW HAS ITS TWITTER ACCOUNT COMPROMISED BY CRYPTOCURRENCY SCAMMERS.” “…it appears that hackers seized control of the moribund Twitter account and gave it a new lease of life promoting cryptocurrency scams.

ZDnet: US makes an example of Indian call center scam artists with stiff sentences – “The worst offenders have been thrown behind bars for up to 20 years… a number of call centers were established in Ahmedabad, India, in which operators impersonated the IRS and USCIS… in order to threaten US victims with arrest, prison, fines, and deportation unless they paid money they apparently owed.”
An excellent article has just been published by my ESET colleague Lysa Myers. Companies actually compound the phishing problem when they send poorly thought-out messages that are indistinguishable from phishing messages, both to their own staff and to customers (some banks are particularly culpable here). As a result, recipients of such messages are conditioned into accepting without suspicion messages that don’t conform to good practice, and are more susceptible to being taken in by phishing messages. Hook, line, and sinker: How to avoid looking ‘phish-y’ In addition, Lysa points out an issue I hadn’t really considered: “An increasingly common scenario is phishy-looking emails sent by Software as a Service (SaaS) apps like those for fax or shipping services, human resource or accounting portals, collaboration tools, newsletters or even party planners.”
Another colleague (and long-time friend), Bruce P. Burrell, expands on the story I referred to briefly here – Sextortion and leaked passwords – with this article: I saw what you did…or did I? – “It might seem legit but there are several reasons why you should not always hit the panic button when someone claims to have your email password.” Not just a rehash of the news story, but the precursor to what I expect to be a very useful second article with advice from a seasoned security researcher.
