Investigators from Microsoft's Digital Crimes Unit (DCU) have disrupted the network behind the dangerous RaccoonO365 infostealer malware that targeted the usernames and credentials of Office 365 users after being granted a court order in the Southern District of New York. The operation saw a total of 338 websites linked to the popular malware seized and its technical infrastructure disrupted, severing RaccoonO365 users' access to their victims.

According to Charlie Eriksen, malware researcher at Aikido, the attacker appears to be the same one who targeted Nx at the end of August - a campaign in which developers' secrets, such as credentials, were posted to public GitHub pages. Socket and Step Security first reported the latest round of attacks on September 15, with 40 packages affected, but Eriksen has since seen 147 additional packages compromised through similar means, including those from security giant CrowdStrike.

As enterprises continue to shift their operations to the browser, security teams face a growing set of cyber challenges. In fact, over 80% of security incidents now originate from web applications accessed via Chrome, Edge, Firefox, and other browsers. One particularly fast-evolving adversary, Scattered Spider, has made it their mission to wreak havoc on enterprises by specifically targeting sensitive data on these browsers.

To manipulate targets into engaging and downloading ScreenConnect, the attackers employ advanced deception techniques built around impressive impersonations and familiar business contexts, effectively creating workflows that align with end-user expectations,

Popular password manager plugins for web browsers have been found susceptible to clickjacking security vulnerabilities that could be exploited to steal account credentials, two-factor authentication (2FA) codes, and credit card details under certain conditions. The technique has been dubbed Document Object Model ( DOM)-based extension clickjacking by independent security researcher Marek Tóth, who presented the findings at the DEF CON 33 security conference earlier this month.

The phishing attack bypasses a multifactor authentication scheme based on FIDO, the standard considered immune to credential phishing attacks, leading to unauthorized access.

"The threat actor added code in the installed binaries of the fake NetExtender so that information related to VPN configuration is stolen and sent to a remote server," Ganachari said.
