The websites of Sierra Leone Commerical Bank and the Federal Depository Library Program were hacked and replaced with pro-Iran messages on Sunday morning.
The Sierra Leone Commerical Bank's website was displayed as "H4ck3D IRANIAN HACKER" in Google search results. Screenshots posted on Twitter showed a drawing of former IRGC Quds Force commander Qasem Soleimani, who was killed in a US airstrike on Friday with the words "hacked by Iranian hacker, hacked by shield Iran."
The Federal Depository Library Program's website was hacked to display an image of President Donald Trump bleeding from his mouth with a fist hitting him, along with the words "Hacked by Iran Cyber Security Group HackerS," according to CNN.
Both sites are currently inaccessible as of 6:20 a.m. Israel time.
"We are aware the website of the Federal Depository Library Program (FDLP) was defaced with pro-Iranian, anti-US messaging," said Sara Sendek, a spokesperson for the Department of Homeland Security's Cybersecurity and Infrastructure Security Agency, according to CNN. "At this time, there is no confirmation that this was the action of Iranian state-sponsored actors. The website was taken off line and is no longer accessible. CISA is monitoring the situation with FDLP and our federal partners."

"The Iranian regime telling Iraq’s government what to do puts Iraqi patriots' lives at risk," warned Pompeo.US President Donald Trump warned in a tweet on Saturday night that if Iran targeted Americans or American assets, the US would strike a list of 52 Iranian targets "(representing the 52 American hostages taken by Iran many years ago), some at a very high level & important to Iran & the Iranian culture, and those targets, and Iran itself, WILL BE HIT VERY FAST AND VERY HARD. The USA wants no more threats!"
