A number of websites belonging to the Israeli government were felled in a distributed denial-of-service (DDoS) attack on Monday, rendering the portals inaccessible for a short period of time.
“In the past few hours, a DDoS attack against a communications provider was identified,” the Israel National Cyber Directorate (INCD) said in a tweet. “As a result, access to several websites, among them government websites, was denied for a short time. All websites are now back to normal. “
A distributed denial of service attack (or DDoS) is an attempt to block normal traffic from a target server or service. It involves flooding the infrastructure and victim with junk traffic, using compromised computers and IoT devices.
The development comes after internet watchdog NetBlocks reported “significant disruptions” registered on multiple networks supplied by Israel’s telecom providers Bezeq and Cellcom.
The INCD has not pinned the attacks to a specific threat actor, but Jerusalem Post alluded to the possibility that the incident could have been the work of an Iranian-affiliated hacker group in retaliation for alleged attempted sabotage of the nation’s Fordow nuclear enrichment plant.
This isn’t the first DDoS attack on government IT infrastructure. The ongoing Russo–Ukrainian conflict has opened the door to a number of DDoS campaign campaigns.
On top of that, a vulnerability in Mitel MiCollab and MiVoice Business Express collaboration systems was recently weaponized to carry out sustained distributed denial-of-service (DDoS) attacks for up to 14 hours with a record-breaking amplification ratio of 4. 3 billion to 1.
