This recent security alert highlights a wave of deceptive SMS messages that emerged on Tuesday night, causing confusion and alarm among recipients. Investigations by the National Cyber Directorate indicate these messages contain links designed to download malware onto victims' devices. It's believed that Iranian and pro-Palestinian hacker groups exploited a compromised SMS distribution service to send these messages.
If you've clicked a link but didn't download or install anything, you may be safe, but the investigation is ongoing. Some messages link to the Iranian group Anonymous Sudan, which has previously targeted Israel with Russian hacking tools. Recently, two members of this group were arrested at the request of the U.S., but it remains uncertain if they were the only ones involved, as there are concerns about Kremlin-sponsored hackers.
One particularly concerning message impersonated Home Front Command, urging users to download a new app "as soon as possible." Check Point's analysis confirmed it is a malicious scam, aimed at compromising user devices. The app can access sensitive information, including contacts and media files, and may operate without the user's knowledge, potentially silencing emergency alerts.
Another message, under the name "sinvar" (a misspelling of Hamas leader Yahya Sinwar), threatened retaliation, claiming "Sinwar's murder has opened the gates of hell for the Jews," linking to an Iranian group known for attacks on Israeli institutions.
The Cyber Directorate reported numerous citizen complaints about these impersonating messages and has disabled the harmful link. They advise that if you clicked the link without further action, your device is likely unaffected. It's crucial to only download apps from official stores and to remain vigilant, reporting any suspicious activity to the designated hotline.
Be aware that some malware can infiltrate devices without requiring downloads. Always exercise caution, and if your device shows signs of slowing down or other issues, consider seeking professional help.
