Cyber Round-up for 18th February

Welcome to Ironshare’s Cyber Round-up, where we look back at the events of that last week and year to cover some of the news, posts, views, and highlights from the world of Security. 


In this week’s round-up:

Security News

Governments Cautious Of High Impact Ransomware Increase.

With ransomware attacks becoming more frequent and sophisticated in design it has required governments to act to protect organisations, businesses and individuals. A recent collaboration between United States’ Cybersecurity and Infrastructure Security Agency (CISA), the UK’s National Cyber Security Centre (NCSC), and the Australian Cyber Security Centre are allowing these organisations to better understand the methods and techniques being used by cyber criminals using ransomware to extort. The report produced by the collaboration concluded that cyber criminals seem to be:

  • Targeting poorly-defended cloud infrastructure to steal data, encrypt information, and – in some cases – deny access to backup systems.
  • Targeting managed service providers (MSPs), impacting all of an MSP’s clients at once.
  • Attacking industrial processes by either affecting connected business systems or developing code to interfere with critical infrastructure.
  • Attacking the software supply chain and using it as a method to access multiple victims through a single initial compromise.
  • Targeting organisations on holidays and weekends, where they might have more impact and there are fewer IT support personnel in place to handle emergencies.

Emotet New Attack Vector Infecting Businesses

A new attack method for the much unloved Emotet Malware has been reported by Unit42. Emotet has been recorded trying to infect devices through the use of malicious email attachments. Emotet can make this email seem more legitimate by thread hijacking that allows the creation of fake replies to emails that seem legitimate. This email contains an attachment to an excel document that contains a macro that users are asked to enable. If enabled it will download Emotet from an attacker owned server onto the device. The attachment in the email are often a zip file that contains a password protected excel sheet – the password will be noted in the email. This is an attempt to bypass email attachment scanning tools as it can’t be read. More detail are available in the above link.
