Iranian government hackers are using Telegram as a way to steal data from hacked dissidents, opposition groups, and journalists who oppose the regime around the world, according to an FBI alert published on Friday.

In the first stage of the attack, the hackers contact their targets and pretend to be a known contact or tech support, and are tricked into accepting a link to a malicious file masquerading as legitimate apps, such as Telegram and WhatsApp.

Once the target installs the malware, the second stage of the attack connects the infected victim with Telegram bots that allow the hackers to remotely command and control the victim’s computer. This allows the hackers to gain remote control of victims’ devices to steal files, take screenshots, and record Zoom calls, according to the FBI.

Using Telegram as a way to remotely control a victim’s device is a common technique by hackers to hide malicious activity among legitimate network traffic, which makes it harder for cybersecurity defenders and anti-malware products to identify.

According to the FBI, the hackers responsible for these attacks are allegedly working for Iran’s Ministry of Intelligence and Security (MOIS).

The FBI said these attacks are an example of Iranian government hackers’ attempts to push the regime’s “geopolitical agenda.

” In the alert, the FBI mentioned the pro-Iranian and pro-Palestinian fake hacktivist group Handala, although it’s not clear if the attacks referenced in the alert were carried out by this group.

Earlier this month, Handala claimed responsibility for an attack on medical tech giant Stryker, which resulted in wiping tens of thousands of employee devices.

In an 8-K filing with the U.

Securities and Exchange Commission on Monday, Stryker said it is still recovering from the hack. Justice Department accused Handala of being a front for Iran’s government, specifically the MOIS, and for being behind the Stryker hack. At the same time, the FBI took down and seized two websites linked to Handala, and two other sites linked to another Iranian hacktivist group called “Homeland Justice.

” In the recent FBI alert, the bureau said the two groups are linked and controlled by the MOIS.

An FBI spokesperson said in an email that the bureau “has nothing additional to add. ” Telegram’s spokesperson Remi Vaughn said that the platform’s “moderators routinely remove any accounts found to be involved with malware. ” Updated to include the FBI’s and Telegram’s response
