Cyber Threat Report | June 2023

Looking back at the month of June, we continue to deliver the latest insights within the cybersecurity landscape. We turn special attention to the exploited MOVEit Transfer vulnerabilities that have targeted over fifty organizations worldwide.

On this note, AMATAS CEO, Marko Simeonov, reminded,

“Organizations need to be especially cautious when it comes down to their third-party service providers or vendors. It’s not enough anymore to have solely internal cybersecurity procedures. This exploited vulnerability should be your red light to reconsider your cybersecurity efforts to be more encompassing as to external communication.”

Apart from data breaches due to third-party service providers, this month, we observed:

  • Microsoft and iOS vulnerabilities;
  • politically-attributed spyware campaigns and the rise of a new, Russian state-sponsored group;
  • three years after EncroChat’s encryption.

Cybercrime Breaking News

The BBC, British Airways, and UK drugstore Boots were affected by a data breach at payroll provider, Zellis. Thousands of staff data may have been exposed as a result of a zero-day vulnerability that impacts a file-transfer tool that is used by Zellis – MOVEit Transfer. 

Other victims of the MOVEit vulnerability include several US federal government agencies, Shell, Gen (the cybersecurity giant behind Norton, Avast, and LifeLock), Siemens Energy, and more than fifty companies. 

The vulnerability, CVE-2023-34362, was added to Cybersecurity and Infrastructure Security Agency (CISA)’s website while patches were released. By the end of the month, two more MOVEit vulnerabilities were tracked (one of which is CVE-2023-35708). 

Writing to Reuters, the “cl0p team” claimed responsibility for the breaches and threatened to publish victim data on their website. The Microsoft Security Intelligence Team has also attributed the vulnerability, to Lace Tempest, the group running the Clop website. But, towards the end of June, Clop hackers to the BBC claiming that they aren’t behind the hack on Zellis, “We don’t have that data… We are an old group and have never deceived anyone if we say that we do not have information, then we do not have it”. 

At the beginning of the month, cybersecurity experts and MOVEit creators, Progress Software, warned that the vulnerability “could lead to escalated privileges and potential unauthorized access to the environment”.
