Amir Hossein Golshan, 25, of Los Angeles, was recently sentenced to 96 months in prison for perpetrating multiple cybercrime schemes, including one involving SIM swapping.  Between April 2019 and February 2023, Golshan caused roughly $740,000 in losses to hundreds of victims as a result of various online scams and unauthorized access to digital accounts.  According to the Department of Justice (DoJ), Golshan took over victims’ social media accounts, impersonated Apple support, and engaged in Zelle payment fraud schemes.

Researchers have discovered a case of "forced authentication" that threat actors could exploit to leak a Windows user's NT LAN Manager (NTLM) tokens by tricking the victim into opening a specially crafted Microsoft Access file. The attack exploits a legitimate database management system solution feature that enables users to link to external data sources such as a remote SQL Server table. NTLM, a challenge-response authentication protocol introduced by Microsoft in 1993, is used to authenticate users during sign-in.
