Pro-Iran group turns Ubuntu DDoS into shakedown

Summary

Pro-Iran crew turns DDoS into shakedown as Ubuntu.com stays down 313 Team tells Canonical: pay up or the packets keep coming Canonical says its web infrastructure is under attack after a pro-Iran hacktivist group instructed its members to target the open source giant. "I can confirm that Canonical's web infrastructure is under a sustained, cross-border Distributed Denial of Service (DDoS) attack" a Canonical spokesperson told The Register. "Our teams are working to restore full availability to all affected services. We will provide updates in our official channels as soon as we are able to." Known best for managing the development of Ubuntu, the distro's main website is down at the time of writing, and has been for several hours. The hacktivist group The Islamic Cyber Resistance in Iraq – 313 Team claimed repsonsibility for the 503 errors Ubuntu's website was returning on Thursday evening, announcing via its Telegram channel that the attack was scheduled to persist for four hours. More than 12 hours later, the attack continues to disrupt Ubuntu's main website and many of its subdomains, although some, including its Archive and Discourse pages, remain up and running. - Feds disrupt monster IoT botnets behind record-breaking DDoS attacks - Iran's cyberwar has begun - Polish cops bust alleged teen DDoS kit sellers – youngest just 12 - DDoS deluge: Brit biz battered as botnet blitzes break records 313 Team sent a follow-up message to its Telegram group, directed at Canonical, which indicates the group is veering away from hacktivism and toward full-on extortion: "There is a simple way out. We have emailed you with our Session Contact ID. If you fail to reach out, we will continue our assault. You are in an awful position, don't be foolish." The service disruption at Ubuntu means users cannot download any versions of its distros through the usual channels, nor can they log into their Canonical accounts. Canonical promised to provide regular updates when it has new information to share. 313 Team has claimed responsibility for similar DDoS atatcks on the likes of eBay's Japan and US divisions, as well as BlueSky in just the past month alone. Why the group is targeting London-based Canonical remains unclear and no reason was given via its Telegram channel. It is presumably because Ubuntu is one of the most popular Linux distros. ®

US and Iran trade strikes as tensions escalate amid renewed conflict - US Central Command has struck three Iranian oil tankers, including one near the Kharg Island export hub, after Iran's Islamic Revolutionary Guard Corps fired ballistic missiles at two US Navy vessels.

- Admiral Brad Cooper declared that the US would exact a higher economic cost for attacks on its ships, confirming that no American personnel were harmed during the strike. - Iran's Revolutionary Guard retaliated by threatening further attacks on US military ships, claiming to have targeted three US-linked vessels and three tankers navigating unauthorised routes in the Strait of Hormuz.

- The Iranian Red Crescent has requested an International Criminal Court investigation into a suspected US strike on an Iranian wedding that left at least five people dead, accusing Washington of war crimes. - The recent exchanges represent a dangerous deepening of the wider conflict between the US, Israel, and Iran, which has flared repeatedly since initial strikes in February.

Iran said its forces attacked a US naval drone trying to enter the Strait of Hormuz, hours after targeting ships in retaliation for American strikes on three oil tankers. The latest round of clashes, which began with US raids last week, comes amid a deadlock in their six-month war.

Iran has maintained its stranglehold on the strategic Strait of Hormuz while Washington continues a counter-blockade of Iranian ports. Washington is also seeking to choke Iran's economy, rolling out sanctions on entities with financial links to the Islamic republic in a bid to force it into submission.

The Islamic Revolutionary Guard Corps, the ideological arm of Iran's military, said today that it "attacked an American military unmanned surface vessel" attempting to enter the strait, according to a statement carried by state television. Hours earlier, the IRGC said its naval forces "targeted three oil tankers on the unauthorised route of the Strait of Hormuz and three vessels affiliated with the child-killing America in other areas".

It warned ships not to attempt to transit by unapproved routes. Yesterday, US Central Command (CENTCOM), which oversees American military operations in the region, said it struck tankers linked to the Iranian Guards, accusing the most powerful arm of the Iranian military of unsuccessfully firing at American warships.

"Following Iran's failed attacks, CENTCOM permanently disabled the IRGC crude oil carriers M/T Downy off the coast of Kharg Island and M/T Stark 1 near Jask," it said. "American forces also completely destroyed the unladen crude oil carrier M/T Kylo ...

in the Gulf of Oman, striking the vessel in multiple critical locations to render it inoperable after the crew was directed to abandon ship," he said. Video posted by CENTCOM showed large fireballs and billowing flames after projectiles slammed into the ships.

The three vessels were "part of a multibillion-dollar shadow network that funds the IRGC and its regional proxies", it said. 'Higher economic cost' The IRGC meanwhile claimed the two American warships they targeted had been "forced to retreat" after "suffering damage", but CENTCOM said those ships successfully evaded Iranian attacks.

CENTCOM commander Admiral Brad Cooper said after the operation: "If you shoot at two of our ships, we will impose an even higher economic cost - taking out three of yours." The Iranian foreign ministry hit out at Washington over the strikes on oil tankers, calling them "illegal and aggressive actions".

A correspondent for Iranian state TV in Jask in the southern province of Hormozgan said one of the tankers was empty and the second was carrying oil. The crews were transported to shore on lifeboats, they said. Another state TV correspondent on Kharg Island said the attack there caused no casualties.

Iran's Khatam-al Anbiya central military command warned that if the US continued its attacks, then Tehran's retaliation against US warships would be "more severe than before, and there is a possibility of their expansion". The administration of US President Donald Trump has tried to downplay the significance of the six-month conflict, which has proven increasingly unpopular at home as midterm elections near.

US Vice President JD Vance went so far as to say that he "wouldn't call it a war". Mr Trump reiterated that view on Friday, calling the war "small potatoes" for Washington. Iran's Security Chief Mohsen Rezaei warned this week that the Islamic republic had adopted a "new strategy" against Washington that "will shatter your foundations".

The US has been trying to step up pressure on Tehran in a bid to wrestle control of the Hormuz strait, through which one-fifth of world oil supplies previously flowed. A fragile ceasefire between the two sides collapsed in July after attacks on commercial ships in the strategic waterway.

Mr Trump has in recent weeks repeatedly threatened to claim sovereignty over the strait, even posting a map showing it as "new US territory". Mr Vance has insisted the US will not reopen talks with Iran until it ends attacks on commercial shipping in Hormuz.

CAIRO (AP) — Iran said Sunday it struck an unmanned U.S. vessel trying to enter the Strait of Hormuz, the latest salvo in a new flare-up of fighting between the two countries. The U.S. did not immediately confirm the purported attack, which came a day after the U.

S. military said forces struck three Iranian oil tankers in response to a missile attack on Navy warships. The war began with U.S. and Israeli attacks on Iran on Feb. 28. But since a ceasefire agreement was announced in June, on-and-off fighting has persisted with both sides trying to inflict military and economic pain as negotiations have collapsed.

Strikes come about a week after fighting resumed The U.S. and Iran resumed attacks last week, following a month of relative calm, with the Strait of Hormuz and Iranian communities along it again being targeted. At least five people were killed earlier in the week during a U.

S. bombardment of southern Iran. The Trump administration appears to have adopted a dual-prong approach to the conflict, responding militarily to attacks on the strait while going after foreign financial institutions that handle Iran’s money.

But Tehran's hard-line new senior leaders have signaled the willingness to dig in after weathering decades of sanctions. Iran has found ways over the years to circumvent sanctions, and now the U.S. blockade, and get its oil to buyers to help ease growing economic pressures.

That relies in part on a shadow fleet transporting its oil. Meanwhile, Iran's nuclear program, the issue that contributed to the outbreak of the war, was meant to be addressed in negotiations that fell apart soon after the U.S. and Iran signed a memorandum of understanding in mid-June.

Diplomats say the U.S., Britain, France and Germany seek to refer Iran to the U.N. Security Council for failure to comply with its nuclear nonproliferation obligations. Instead, Tehran's new leverage focuses on the Strait of Hormuz that is crucial to global oil and natural gas shipments and was seen as an international waterway before the war began.
