He said surveillance systems were in place to monitor increased mosquito activity and shifting bird migration caused by warmer weather.

The hackers used a combination of techniques to gain access, the report said, including guessing passwords.Another method used is called spearphishing, where fake emails are targeted at specific people who have access to systems.

They are presented with a fake page where they enter their login details, or encouraged to click a link which then installs malicious software."The subjects of spearphishing emails were diverse and ranged from professional topics to adult themes," the report said.A vulnerability in Microsoft Outlook was also exploited to collect credentials "via specially crafted Outlook calendar appointment invitations".

These kinds of techniques have been "a staple tactic of this group for over a decade," Rafe Pilling, director of threat intelligence at Sophos Counter Threat Unit, said.Camera access "would assist in the understanding of what goods were being transported, when, in what volumes and support kinetic [weapons] targeting," he added.

Cyber security firm Dragos told the BBC it had been tracking hacking activity linked to that reported by the NCSC.

It's chief executive Robert M. Lee said that the hackers it followed were not only interested in gaining a foothold in corporate computer networks but would infiltrate industrial control systems where they would be able to "steal important intellectual property and insights for espionage, or position themselves for disruptive attacks".Ji Seok-bin, a 27-year-old who is a regular at Starbucks, said he thought the rule was "too trivial", though he said he understood the logic behind it given the country's heightened political tensions.

"After [Yoon's impeachment] I don't really talk about politics anymore. It feels like the ideological divide has grown so much that conversations often turn into arguments."Starbucks is not alone. The country's biggest search engine, Naver, has disabled autocomplete and related search suggestions for candidates, as it usually does during election season.

A search on Google for Lee, who is widely tipped to win the election, yields phrases like "Lee Jae-myung trial" - a reference to the fact that he is currently embroiled in several criminal trials.A search for the country's conservative presidential candidate Kim Moon-soo brings up a related suggestion for "conversion", as he is widely seen to have "converted" from being a fervent labour activist to a conservative politician.
