Security News > 2024 > April > Microsoft: APT28 hackers exploit Windows flaw reported by NSA

Microsoft warns that the Russian APT28 threat group exploits a Windows Print Spooler vulnerability to escalate privileges and steal credentials and data using a previously unknown hacking tool called GooseEgg.

APT28 has been using this tool to exploit the CVE-2022-38028 vulnerability "Since at least June 2020 and possibly as early as April 2019.".

Redmond fixed the vulnerability reported by the U.S. National Security Agency during the Microsoft October 2022 Patch Tuesday but has yet to tag it as actively exploited in its advisory.

One year ago, U.S. and U.K. intelligence services warned about APT28 exploiting a Cisco router zero-day to deploy Jaguar Tooth malware, which allowed it to harvest sensitive information from targets in the U.S. and EU. More recently, in February, a joint advisory issued by the FBI, the NSA, and international partners warned that APT28 used hacked Ubiquiti EdgeRouters to evade detection in attacks.

Two years later, the U.S. charged APT28 members for their involvement in the DNC and DCCC attacks, while the Council of the European Union also sanctioned APT28 members in October 2020 for the German Federal Parliament hack.

Cisco discloses root escalation flaw with public exploit code.
