The Week in Ransomware – November 3rd 2023 – Hive’s Back

Hive ransomware

Over the past couple of months, ransomware attacks have been escalating as new operations launch, old ones return, and existing operations continue to target the enterprise.

This week, the Toronto Public Library was attacked by the Black Basta ransomware gang, taking many of its online services offline.

Other attacks we learned about this week include ACE HardwareMr. Cooper, and the British Library. While these are not confirmed to be ransomware attacks, they share many signs usually associated with such attacks.

Due to the increasing number of attacks, an alliance of 40 countries will sign a pledge during the third annual International Counter-Ransomware Initiative summit in Washington, D.C., to stop paying ransom demanded.

However, this may be an empty pledge, as federal governments typically do not pay ransomware demands, and it does not prevent local governments from giving into extortion demands.

Microsoft also pledges to bolster security as part of its ‘Secure Future’ initiative by improving the built-in security of its products and platforms to better protect customers against escalating cybersecurity threats.

Finally, new research was released this week about ransomware, including:

Hive’s possible return is particularly interesting, as they were previously disrupted after the FBI hacked Hive’s servers and seized infrastructure.
