The pace of online attacks hasn't slowed nearly halfway into the year. Fire up a digital security website in your browser, and you are sure to find a nearly endless list of digital break-ins and other crimes in the virtual realm. Let's shift the spotlight to some of the most newsworthy hacks and other digital attacks of the final week of May.

Ransomware Connection Highlighted

A supposed connection between different types of ransomware has been identified. The connection links Chaos, Onyx, Yashma, and other ransomware to one another. The digital criminals responsible for the forms of ransomware share a common thread in the ransomware building tool known as Chaos. The latest versions of ransomware have struck businesses, educational institutions, and organizations of just about every type and size.

PyPi Package Used to Steal AWS Keys

A PyPi package known as "CTX" has made it surprisingly easy for hackers to pilfer AWS keys. The package in question, along with another known as "Phpass," are used as trojans. The attack also uses maintainer email domains. Such domains that have lapsed are used for recreating new email maintainers with the goal of controlling packages. Those who buy domain names have the potential to connect them to email hosting services used to steal sensitive information and use it for manipulation or subsequent sale on the dark web. If you are not yet monitoring the dark web, now is the time to start.

ICS Flaws and RCE

ICS flaws have the potential to spur RCE. RCE, short for remote code execution, sets the stage for miscreants to control computers and networks from afar. Digital security researchers identified nearly ten susceptibilities with Cisco Talos. Two of the weaknesses are featured as the Open automation Software platform components. The vulnerabilities are extreme to the point that they allow online attackers to obtain login credentials, including usernames and passwords. Aside from adding network segmentation, updating the system to protect against the latest online threats will also help.

Microsoft Office Vulnerable as a Result of Follina Bug

A zero-day bug known as the "Follina bug" allows for older versions of Microsoft Office to prove susceptible to online aggression. The malware moves through remote servers and sets the stage for the malicious code to run on target computers. The code runs by way of remote features used on Microsoft Word templates. The aggression takes advantage of Microsoft Word's remote template. Stay tuned as a patch might soon be issued to offset or at least mitigate the potential damage caused by the Follina bug.

REvil Cyber Gang Returns

The REvil cyber criminal hacking collective has returned to little fanfare. The hacking collective is back on the offensive, launching DDoS attacks. At the moment, REvil is targeting Akamai and the organization's clients. The most powerful of the attacks were conducted in mid-May. The timing of the offensive is intriguing as REvil went silent about one year before its bombastic return. The latest REvil attack is of the Layer 7 variety. The attack attempts to convince the target into forking over an extortion payment, typically in the form of cryptocurrency.
