Delaware County says June cyberattack disrupted services for Glenolden-area residents
By Brian Bateman
Delaware County officials said a sophisticated cybercriminal attack in late June disrupted county services used by residents in Glenolden and throughout the county. The county disclosed the incident on July 10, after unauthorized activity affected county network systems between late June and July 10.
Officials said attackers gained limited access to data maintained within the county network. The county also said several other attempts to gain unauthorized access were blocked.
What the incident means for Glenolden
Glenolden is a Delaware County municipality, but the available information describes an attack on Delaware County government systems—not a breach of Glenolden Borough’s municipal government.
Residents who use county offices or online county services could encounter delays, changed service procedures or follow-up notices as the county responds. The county has confirmed that services were disrupted, but it has not publicly identified all of the affected services in the available material.
The disclosure does not establish whether records specific to Glenolden residents were accessed. It also does not say that personal information was stolen. Officials have described access to county network data as limited, without publicly specifying which data was involved.
What is known about the timeline
The intrusion occurred in late June 2026. The incident window identified in the available material runs from June 26 through July 10, when the county’s disclosure was reported. The exact date on which the intrusion began has not been specified beyond that late-June timeframe.
During the response, county services were disrupted. At the same time, county officials said some unauthorized-access attempts were blocked, indicating that not every attempt succeeded. The county characterized the incident as part of a sophisticated cybercriminal attack.
What remains unanswered
The county has not publicly quantified the number of affected residents. The available information also does not identify whether any Glenolden-specific records were accessed, which categories of data were involved or whether any individual’s information was taken.
No further county deadline or next response step is identified in the approved material. For now, the confirmed public facts are limited to the network intrusion, the limited access to county data, blocked attempts and disruption to county services.
