Australia's data regulator says organizations hit by ransomware may be underreporting data breaches because they haven't thoroughly figured out if data was taken. But an "absence of evidence" of a data breach in a ransomware attack isn't sufficient to declare that no data was taken.
Threat intelligence researchers are looking closely at REvil, the ransomware gang that infected up to 1,500 companies in a single swoop. A look at the group's online infrastructure shows clear lines to Russian and U.K. service providers that, in theory, could help law enforcement agencies but don't appear eager to...
The saga around how scores of aging Western Digital NAS devices were remotely erased has deepened with the discovery of a new, unknown software vulnerability. The situation underscores the problems of still-used devices that have been abandoned by manufacturers.
Bitcoin has enabled fast payments to cybercriminals pushing ransomware. How to deal with bitcoin is the subject of a spirited debate, with some arguing to restrict it.

It has been an open question as to how a half-dozen hacking groups began exploiting Exchange servers in an automated fashion in the days leading up to Microsoft's patches. But there are strong signs that the exploit code leaked, and the question now is: Who leaked it?
Tales of poorly secured internet-connected cameras come along regularly. But the latest installment seems especially egregious because it involves Verkada, a widely used "surveillance camera as a service" startup, and led to remote hackers being able to spy on customers via their own cameras.
SonicWall was recently attacked via a zero-day flaw in one of its own products. Curiously, SonicWall hasn't said much about the extent and damage of the breach since its announcement. But there are strong indications it may have been targeted by an extortion attempt.
Bloomberg has stood firm on its controversial story from two years ago asserting that China implanted a tiny chip on motherboards made by Supermicro. But rather than proving its contention in a follow-up, it may have inflicted more reputational damage upon itself.
The Florida city that experienced a breach of its water treatment system used now-unsupported Windows 7 machines, shared the same password for remote access and had no firewall. The incident is likely to raise questions about the vulnerability of critical infrastructure in small towns on slim IT security budgets.
Several data breaches stemming from unpatched vulnerabilities in Accellion's File Transfer Appliance have been revealed. What went wrong? Where does the fault lie? And what can organizations do about it?
MAXEX, a company that develops a digital trading platform for the secondary mortgage market in the U.S., leaked 9 GB of internal documentation as well as full mortgage applications for 23 individuals. The data was released by a Swiss-based developer who apparently was unaware it was sensitive.
