The cyber security firm Symantec, makers of Norton antivirus software, which uncovered the cyber espionage group’s existence, has dubbed it “Leafminer”. It said the group has been active since the beginning of 2017, but has “significantly ramped up its activities” in 2018 and is currently involved in dozens of ongoing attacks.

In a report published on Wednesday, Symantec said that its security experts managed to obtain what appears to be Leafminer’s master list of targets. The list is written in the Farsi language and contains just over 800 organizations, which according to Symantec researchers is “an ambitious goal” for any cyber espionage group. The organizations listed on the target sheet come from a variety of sectors, including government, transportation, the financial sector, energy and telecommunications. But the majority of the group’s targets appear to be in the petrochemical and government sectors. Additionally, virtually all of Leafminer’s targets are located in the Middle East and North Africa, in countries such as Israel, Egypt, Bahrain, Qatar, Kuwait and the United Arab Emirates. Some of the group’s targets are located in Afghanistan and Azerbaijan.

Symantec said its researchers observed the Leafminer hackers execute attacks in real time on at least 40 targets in the Middle East, including on the website of an intelligence agency in Lebanon. According to the cyber security company, Leafminer uses a variety of hacking tools, including custom-designed malware and some publicly available software. The group’s operational sophistication is also varied, and ranges from complex, multilayered attacks to brute-force login attempts. Symantec said it concluded that the cyber espionage group originates from Iran because its master target list is written in Farsi and because Iran is virtually the only country in the Middle East that is missing from the target list. However, it said that it did not have sufficient evidence to link Leafminer to the Iranian government. In a separate development, Germany’s domestic intelligence agency, the Federal Office for the Protection of the Constitution (BfV), said this week in its annual report that the government of Iran has significantly expanded its cyber warfare capabilities and “poses a danger to German companies and research institutions”.
