**Hacker Pranks: Stryker Attack Mirrors Tactics Used in Iran-Aligned Hacks**

A recent cyberattack on medical technology company Stryker Corp. has raised concerns about the increasing sophistication of pro-Iranian hacking groups. The attack, which resulted in the deletion of data on some devices, is believed to have been carried out by the group Handala, which has been linked to Iran's Ministry of Intelligence and Security. This attack marks a significant escalation in the group's tactics, which have evolved from simple website defacement to more potent sabotage and well-timed politically motivated attacks.

**Handala's Rise to Prominence**

Handala, also known as the "shadowy pro-Iranian hacking group," has been making headlines in recent months for its brazen attacks on high-profile targets. The group's tactics have been described as a combination of hacktivist and nation-state-sponsored cyberespionage. According to Justin Moore, a senior manager of threat intelligence at Palo Alto Networks Inc., Handala operates as a state-directed front for Iran's Ministry of Intelligence and Security.

Handala's tradecraft has significantly evolved over the past two years, with a focus on disrupting organizations tied to Israel or the US military. The group has targeted high-profile Israeli politicians, including former Prime Minister Naftali Bennett, and has leaked sensitive personal information from his phone. In another incident, Handala targeted Israel's Soreq Nuclear Research Center, leaking photos from inside the facility and publishing a list of scientists who were allegedly working on a particle accelerator project.

**The Stryker Attack**

The Stryker attack is believed to have been carried out in retaliation for a US missile strike that allegedly hit an Iranian school. Handala claimed responsibility for the attack, saying it had targeted Stryker because of the company's connections to Israel. In 2019, Stryker acquired the Israeli company OrthoSpace, and the company has also previously worked with the US military, winning a $450 million contract to supply medical devices to the US Department of Defense.

The attack resulted in the deletion of data on some devices, and Stryker has stated that it expects the breach to continue disrupting operations. The company has not confirmed that pro-Iranian hackers were behind the breach, but Handala's involvement would mark its largest incursion yet.

**Wiper Attacks and State-Sponsored Cyberespionage**

Wiper attacks, which involve the deletion of data from affected devices, are a rare occurrence in the world of cyberattacks. However, they are often the work of state-sponsored cyberespionage groups. Russian hackers have used wiper attacks in the past, targeting Ukrainian targets in 2022, and North Korean hackers have also employed this tactic, targeting Sony Pictures in 2014.

**The Role of Pro-Iranian Hacking Groups**

Pro-Iranian hacking groups have been accused of combining disruptive attacks with propaganda and disinformation meant to overstate their prowess. Cybersecurity specialists have warned that these groups would play a significant role in any conflict, and that their tactics would align with Iran's broader approach to fighting the war.

The Islamic Revolutionary Guard Corps has launched missiles against targets throughout the Middle East, regardless of their level of direct involvement in the fighting. The Iranian state-linked media outlet Tasnim has published a list of US companies whose offices and products are considered legitimate targets in the conflict, including American technology firms.

**Conclusion**

The Stryker attack marks a significant escalation in the tactics of pro-Iranian hacking groups, and highlights the increasing sophistication of these groups. As the world becomes increasingly dependent on technology, the risk of cyberattacks continues to grow. It is essential that companies and governments take steps to protect themselves against these threats, and that cybersecurity specialists continue to monitor and analyze the tactics of these groups.
