IT administrators are being warned a new backdoor has been discovered allowing a hacker to enter a system. The really bad news is that that can be installed on Windows, Linux and Mac servers. The alert comes from researchers at Intezer. Called Sysjoker, it isn’t clear how the backdoor gets loaded onto victims’ systems. One possibly is its an infected TypeScript file downloaded from an open-source library. A news report quotes another researcher saying the malware could have been hiding in a video transport stream. Whatever the source, IT administrators should use memory scanners to see if Sysjoker is hiding in memory, and leverage an endpoint detection or a security information and event management solution to search for indicators of compromise. In addition, all staff have to be reminded to only download files from trustworthy sources.
Another warning is going out to IT administrators with QNAP data storage systems. The hackers behind the Qlocker ransomware are again going after internet-connected QNAP network-attached storage devices, according to the Bleeping Computer news site. The new ransomware campaign started January 6th. Administrators are reminded that storage devices don’t have to be open to the internet.
Some people believe blockchain is the best thing since sliced bread. However, tight security has to be enforced for anything tied to a blockchain. Investors hoping to build an Ethereum blockchain-supported municipality called CityDAO in Wyoming found that out the hard way. According to Vice.com, investors lost over $100,000 in cryptocurrency after they were tricked into going to a phony website to buy land for the so-called digital city. They went there because a hacker took over the account of CityDAO on the Discord gaming chat platform, where messages about the digital city were posted. The crook made a fake screenshot suggesting the administrator of that Discord site was scamming people. Trying to show his innocence, the admin let the scammer see his Discord console. That enabled the scammer to get control of the Discord account even though it was protected with two-factor authentication. Then the crook published links to a fake website supposedly selling land for the digital city, where some investors deposited money. That money is now gone.
Finally, the COVID-19 pandemic has not only played havoc with the work of IT security teams. It’s also forced the cancellation of today’s opening session of a special United Nations committee meeting on cybercrime in New York. It was to start 10-days of meetings towards drafting an international treaty to help fight online crime. The final draft is scheduled to be presented the UN General Assembly in 2024. No date has been set yet for the start of the New York session. A second session is scheduled at the end of May in Vienna.
