Canadian IoT device manufacturer Sierra Wireless reported Tuesday it had suffered a ransomware attack over the weekend, forcing it to halt production. The attack has disrupted its website and some internal operations.
Attackers are exploiting a critical remote code vulnerability in F5 Networks' BIG-IP server network traffic security management platform, for which the company released patches on March 10. The vulnerability is considered highly critical.
There has been a spike in web shells being detected as ransomware gangs and other attackers increasingly target vulnerable on-premises Microsoft Exchange servers following publication of proof-of-concept attack code for ProxyLogon, which is one of four zero-day flaws patched by Microsoft in early March.
A Swiss national who recently highlighted flaws in Verkada surveillance cameras has been charged with criminal hacking by a U.S. federal grand jury and accused of illegally accessing and leaking data from numerous organizations, apparently including Intel, Nissan and the U.S. National Reconnaissance Office.
This edition of the ISMG Security Report features an analysis of the Microsoft Exchange on-premises server hacks – from who might have leaked the vulnerability exploits to how ransomware gangs are taking advantage of the flaws.

As the Biden administration makes final preparations to respond to the attacks against SolarWinds, it's been confronted by a second major cyberthreat: the hacking of Microsoft Exchange servers throughout the U.S. The response to this incident, however, will likely be much different.
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.
Computer security researchers have acquired an enormous list of compromised email servers from the perpetrators of the mass Microsoft Exchange compromises. But a big question looms: How bad is this situation going to get?
Nearly four years after the WannaCry ransomware hit the world, targeting the EternalBlue vulnerability in Microsoft SMB version 1, security firms say the malware continues to be a top threat detected in the wild by endpoint security products. Why won't WannaCry just die?
Just days after Microsoft disclosed four serious flaws in Microsoft Exchange email servers, attackers are going on a wide hunt for vulnerable machines, some security experts say. The flaws could be exploited for creating backdoors for email accounts or installing ransomware and cryptominers.
An aviation IT company that says it serves 90% of the world's airlines has been breached in what appears to be a coordinated supply chain attack. Customers of at least four companies - Malaysia Airlines, Singapore Airlines, Finnair Airlines and Air New Zealand - may have been affected by the incident.
This edition of the ISMG Security Report features an analysis of key takeaways from the breaches tied to flaws in the Accellion File Transfer appliance. Also featured: Equifax CISO Jamil Farshchi on transforming supply chain security, plus an analysis of how "work from anywhere" is affecting cybersecurity.
Researchers with Microsoft and FireEye are disclosing additional malware used by the hacking group that targeted SolarWinds last December. These second-stage malware variants appear to have been deployed after organizations downloaded the "Sunburst" backdoor hidden in a software update.
Qualys has confirmed that its Accellion File Transfer Appliance software was breached by zero-day-wielding attackers after stolen customer data appeared on the Clop ransomware gang's data leaks site. The security firm's public breach notification comes more than two months after the firm first learned it had been...
