New research reveals just how quickly sensitive data stolen and sold online by cyber criminals can be put to nefarious use, good information to know given the recent escalation in tactics by some ransomware gangs. Specifically, a researcher conducted an experiment in which he lumped real credit card data in with dummy credit card data and dumped the whole thing onto multiple sites. It took just two hours for criminals to respond, initially “nibbling on” the data with bots and scripts.
The FBI’s Portland, Oregon office has published an advisory on building a digital defense during holiday travel, when many people will be connected to networks other than those at their homes or offices and/or have visitors join theirs. For these situations, the FBI recommends not allowing phones, computers, or other devices to auto-connect to free WiFi networks and to set up separate WiFi accounts for guests to segregate any of their vulnerabilities from your sensitive data.
Microsoft has released out-of-band security updates to address a vulnerability in SharePoint Server. An attacker could exploit this vulnerability to obtain sensitive information.

GE produced and released Version 07A04, which fixes the vulnerability. CISA also recommends a series of measures to mitigate the vulnerability. Read the advisory at CISA.
One of the most high-profile ransomware attacks in 2019 was against Norsk Hydro, which is among the world’s leading aluminum production companies.
In the last few days, the cyber criminals behind the Maze ransomware created a public website where they identify their victims who have chosen to rebuild their operations rather than yield to the ransom demands. The move is part of the criminals’ signaling that they will publish the data stolen from their victims if they don’t pay. “For years, ransomware developers and affiliates have been telling victims that they must pay the ransom or stolen data would be publicly released,” said cybersecurity researcher and BleepingComputer founder Lawrence Adams.
CISA has published an advisory on an improper restriction of excessive authentication attempts vulnerability in Omron PLC CJ, CS and NJ. All versions of all three products are affected.
