US Government Bitcoin Ransomware Attack

5224

More than 20 municipalities in the US have been hit by ransomware attacks this year alone, the software has grown rapidly by an internet worm that spreads copies of itself by hacking into other computers on a network. These attacks can be expensive, costing not only the company, but the public time.  Especially if those targeted say they won’t pay. In 2018 hackers demanded the City of Atlanta to pay about $50,000 in bitcoin in ransomware, the city refused and the attack actually ended up costing the city about $17 million to fix the damages. These ransomware attacks have not only recently been in Atlanta but other local governments across the US demonstrate that as these attacks spread more common targets will include schools and hospitals. Can you imagine not being able to graduate or not being able to have your MRI results because all your patient files are being held by these attackers? That’s exactly what happened in Baltimore, May 7th 2019 hackers targeted and digitally seized 10,000 government computers and are demanding around $100,000 in Bitcoins to free them back up. Not only are government employees locked out and are un able to have access to their computers, files and emails, the cities public residents are effected. Services that are utilized for paying water bills are not able to be accessed, paying parking tickets, or property tax payments. Last year Baltimore’s 911 Operating System was down for about a day from a separate ransomware attack.
“Ransomware” attack, where hackers deploy malicious software to block access to or take over a computer system. The basic idea behind ransomware is simple: A criminal hacks into your computer, scrambles your files with unbreakable encryption, and then demands that you pay for the encryption key needed to unscramble the files until it forces the owner of that system to pay a ransom to get their own files back. If you have files that are very important on your computer, you might be willing to pay a lot or succumb to the demands to avoid losing them. The most effective way you can protect your computer from these ransomware attacks is to do regular backups, the malware can only encrypt and delete files that are on your computer. If you are implementing a regular backup of your files, either to an external hard drive or using an online service  and your computer is targeted then you can wipe your infected computer clean. Once clean simply reinstall its software and then restore your files from the backup copy you have. The unfortunate difficulty is most people don’t keep adequate and routine backups so they are more likely to be impacted by these attacks so negatively.

Google has uncovered a rare security flaw for Apple’s computer operating system MacOS…it was a bug that was known by Apple…they are aware and have been notified that it has to be fixed in the next 90 days.  The Google folks are calling the bug, “BuggyCow.”

The bug allows malware already running on a Mac, or a rogue logged-in user, to gain access to the more protected bits of their computer. The Mac would already need to be compromised in some way to actually exploited the bug.  Security is build in layers and in this case at an OS layer that is not the case with the current OS in production.
