A cyber criminal group has posted what it claims are documents stolen from Hackney Council in a ransomware attack.
The publication on the dark web of the personal details of council staff and residents follows "a serious cyber-attack" on the council in October.
Experts said the data was "limited" and "not visible through search engines".
Officials continue to work with the UK National Cyber Security Centre and National Crime Agency to investigate the hack, the council said.
Hackney Council's cabinet member for planning, Guy Nicholson, said the hack had affected services residents relied on, including by disrupting the ability of the council to process land search requests for those buying property.
The council said the vast majority of sensitive or personal information held by the council remained unaffected.
It added that it would support any directly affected people.
