Essential reading for network defenders: CircleCI's report into its recent breach, which began when malware infected an engineer's laptop. After stealing "a valid, 2FA-backed" single sign-on session cookie, attackers stole customers' secrets and gained unauthorized access to third-party systems.
The total amount of ransom payments being sent by victims to ransomware groups appears to have taken a big dip, declining by 40% from $766 million in 2021 to $457 million in 2022 due to victims simply being unwilling to pay, blockchain intelligence firm Chainalysis reports.

In 2023, we'll see ransomware groups exploring new methods to get money from the same victims and entering the "the fifth generation of ransomware." Cybereason field CISO Greg Day shares his predictions for cybersecurity trends this year, from cloud security to deepfake scams.
The prolific ransomware group LockBit has been tied to the recent disruption of Britain's national postal system, as Royal Mail reports it remains unable to send international letters or parcels. While LockBit has enjoyed unusual longevity, could this attack be its undoing?

Anytime critical infrastructure gets disrupted, the first question inevitably seems to be: Was a cyberattack to blame? So it went Wednesday when the Federal Aviation Administration announced a "ground stop," prohibiting all U.S. flights from taking off, due to an overnight system failure.
Researchers have found that Kinsing malware gained access to Kubernetes servers by exploiting misconfigured and exposed PostgreSQL servers. The threat actors gained access by exploiting weakly configured PostgreSQL containers and vulnerable container images.
"If we look at all of the types of issues with cloud breaches, it always comes down to misconfiguration," says Troy Leach of Cloud Security Alliance. "The challenge is: People try to treat cloud environments the same as they've always done on-premises, and that is unfair for both environments."
In the latest weekly update, ISMG editors discuss how collaboration platform Zoom has strengthened its security features, the implications of a new law on medical device security for patient safety, and details on how a zero-day exploit enabled the ransomware hit on cloud computing firm Rackspace.
Hosting giant Rackspace says the recent ransomware attack resulted in Microsoft Exchange data for 27 customer organizations being accessed by attackers. But it says a digital forensic investigation has found "no evidence" that attackers "viewed, obtained, misused or disseminated emails or data."
Netskope has taken on more than $400 million in debt to further develop its SASE platform and expand its go-to-market activities. The convertible notes will allow Netskope to capitalize on being one of the only providers of single-vendor SASE and take advantage of a $36 billion market opportunity.
