An image sent by DNC staffer Alexandra Chalupa shows a warning message she received from Yahoo Mail.
An e-mail message within the Wikileaks dump of Democratic National Committee data suggests that the Yahoo account of one DNC staffer may have been specifically targeted by Russian hackers.
The leaked message from DNC staffer Alexandra Chalupa includes a photo of a screen displaying a pop-up alert in Yahoo Mail warning, "We strongly suspect that your account has been the target of state-sponsored actors."
"Since I started digging into Trump campaign chairman Paul Manafort, these messages have been a daily occurrence on my Yahoo account despite changing my password often," Chalupa reported in the message.
Chalupa was looking into Manafort's work in Ukraine, where Manafort managed the campaign of former Ukraine President Viktor F. Yanukovych who fled to Russia after violent protests against his regime and worked with pro-Russian and Communist Party politicians forming an opposition block to the current government.
The detail, spotted by cybersecurity researcher Matt Tait and posted to the Twitter account @pwnallthethings, offers another hint at the scope of the campaign to collect intelligence on DNC operations by what appears to be Russia-based "actors" operating on the behalf of Russian intelligence.
