Four Iranian Hackers Charged With Cyberattacks On American Firms

Four Iranian nationals charged with multi-year cyber campaign targeting US entities

The US authorities have charged four Iranian men for their alleged involvement in a multi-year hacking operation targeting government and private entities, including the US Department of Treasury and State, defense contractors, and several New York-based companies.

The accused were said to be part of a hacking organization that orchestrated coordinated computer intrusions from 2016 through April 2021. The group’s primary attack vectors included spearphishing and social engineering tactics, such as impersonation, to deceive and gain the trust of their victims, often impersonating individuals, particularly women, to deploy malware onto target computers and compromise accounts.

According to authorities, the hackers managed to compromise over 200,000 employee accounts in one instance and targeted 2,000 employee accounts in another. The four accused have been identified as Reza Kazemifar (he was tasked with testing tools for the group), Hossein Harooni (responsible for running the online network infrastructure used in the cyber intrusions), Komeil Baradaran Salmani (responsible for testing tools for spearphishing campaigns and maintaining infrastructure), and Alireza Shafie Nasab, whose role involved procuring infrastructure, including registering server and email accounts using false identities.

At present, all four defendants are on the loose. The US State Department has announced a reward of up to $10 million for information on the alleged hackers and two Iran-based front companies.

Ukrainian police bust a scam center that defrauded Czech citizens

Ukrainian law enforcement authorities have dismantled a fraudulent call center operating in Odessa, that targeted citizens of the Czech Republic, causing approximately 5.5 million hryvnias (~139,000) in losses.

The scammers used virtual telephony services, masking their numbers, and targeted victims, posing as officials from the state banking regulatory authority.

During the calls, they coerced victims into providing remote access to their phones or computers or divulging their bank card details, subsequently transferring funds to controlled accounts. The stolen funds were then converted into cryptocurrency or laundered to purchase luxury vehicles and real estate. The police conducted a series of raids, resulting in the arrest of nine suspects, the seizure of computers, and mobile phones containing evidence of criminal activity. The suspects were charged with large-scale fraud. They face up to twelve years of imprisonment, along with the confiscation of their assets.

In other news, a joint effort involving the Spanish police, Europol and the Spanish Attaché Office in Romania has dismantled an international criminal syndicate specializing in online scams.
