Cyberattack disrupts credit card payments across Israel’s largest clearing network

Shva, the leading provider of transaction infrastructure and financial information solutions in Israel, has confirmed that a cyberattack caused the credit card processing disruptions that occurred during the morning hours on Tuesday. In a statement issued to the stock exchange, the company explained that "starting at approximately 7:00 a.m., entities connected to the company via the Internet experienced disruptions in processing debit card transactions for approval due to a denial-of-service attack. However, the company's operations as the national payment system continued as normal." Shva further added that "actions were taken to prevent the attack, and full service was restored by 9:50 a.m."

Earlier today, Calcalist revealed that in response to the credit card payment malfunctions, Shva sent a message to the IT teams at credit card companies, stating: "For your information, we are seeing disruptions in communication, and some requests for approval are failing to reach the system. This issue is under investigation." The problem was resolved within two hours.

Shva is Israel's largest provider of communication and computing services for local banking, with its primary focus on clearing credit card transactions. This is not the first incident of its kind this year: in July, Visa Cal cardholders reported unauthorized charges due to a technical glitch at Shva.
