Iranian hacker group Handala claimed on March 11 it had carried out a major cyber operation against Stryker Corporation, the US-listed medical technology company, saying the attack was carried out in retaliation for a strike on a school in Minab and ongoing cyber assaults against what it called the "Resistance Axis" infrastructure.

The group said the operation was "fully successful," claiming it had affected more than 200,000 systems, servers and mobile devices and extracted 50 terabytes of data, according to WANA News on March 11.

Handala claimed Stryker had been forced to close offices in 79 countries as a result of the attack. The group described the company as "deeply rooted in Zionism" and alleged links to what it termed the "New Epstein network," claims that could not be independently verified.

The group said the extracted data was intended to "expose injustice and corruption" and had been passed to what it described as the "free people of the world."

Handala described the operation as "only the beginning of a new chapter in the cyber war," and warned that the period of what it called hit-and-run attacks against Resistance Axis infrastructure was over.

Stryker Corporation had not issued a public statement in response to the claims at the time of publication. The extent of any verified disruption to the company's operations has not been independently confirmed.

According to the Irish Examiner, multiple sources have said that systems in the Cork headquarters have been “shut down” and that Stryker devices held by employees have been wiped out.

The company's login pages coming up on these devices have been defaced with the Handala logo.
