The FBI not too long ago printed a warning stating that ransomware gang OnePercent Group has been attacking corporations within the US since November 2020. This gang of cybercriminals targets people inside a corporation with social engineering ways designed to idiot them into opening a doc from a ZIP file connected to an e-mail. Ransomware is then downloaded and the breach is underway.
Ransomware assaults like those carried out by OnePercent Group have been crippling companies throughout the nation for the reason that FBI first reported a 37% uptick in cybercrime in 2018. The acceleration of digital transformation has additionally left corporations with much less transparency and fewer related safety insights because the implementation of a number of new providers and techniques led to widespread fragmentation.

OnePercent Group assaults
OnePercent makes use of a malicious file attachment by way of phishing e-mail. The group then features entry to a corporation’s community. They’ve been identified to make use of a Phrase or Excel doc inside a ZIP file.

The Cobalt Strike makes use of PowerShell remoting for lateral motion inside the focused community. After that, Rclone causes the organizations information to be exfiltrated, leaving the corporate’s entry to their information and community on the mercy of the hackers.
The ransomware gang then notifies the corporate that they’ve every week to pay them a sure greenback quantity. If the ransom just isn’t paid, then the OnePercent threatens to leak 1% of their information. If the businesses nonetheless refuse to pay, then OnePercent sells the info to the Sodinokibi Group to promote at public sale on the black market.
That is particularly harmful if you consider the truth that the FBI suspects that they is likely to be working with RaaS (ransomware as a service) suppliers like REvil, Maze and Egregor. Whereas the FBI didn’t explicitly point out that the OnePercent Group was working with any identified RaaS suppliers, there have been some signatures which have led professionals to imagine that the group may very well be linked to different hacker teams by way of this kind of service.
RaaS has gained loads of reputation. Identical to different “as a service” choices, hacker teams will provide RaaS software program to different hackers for a charge. However not solely do they supply cybercriminals with the technique of executing a excessive degree cyberattack, RaaS suppliers additionally provide consultations and coaching in order that the ransomware buyer can efficiently infiltrate and exploit one other group for cash, information, or each.

Implement common worker phishing coaching
Worker training is a vital aspect of phishing prevention and risk detection. A latest research signifies that phishing consciousness coaching have to be repeated a minimum of as soon as each six months to ensure that staff to retain the data. Higher degree administration needs to be required to attend these coaching periods as effectively, since these people usually tend to be focused on account of their larger degree credentials.
Frequently monitor the community for vulnerabilities
