Interim Democratic National Committee Chair Donna Brazile warned against perusing the documents released in the latest DNC hack, alleging that they could have viruses which damage your computer.

Brazile urged caution for anyone attempting to download the documents, “given the potential malware risks.” At the same time, she said the hack was carried out by the Russians, particularly the infamous hacker Guccifer 2.0, the same hacker who released DNC documents right before the Democratic National Convention in July, leading to the resignation of Chairwoman Debbie Wasserman Schultz.

The DNC is the victim of a crime — an illegal cyberattack by Russian state-sponsored agents who seek to harm the Democratic Party and progressive groups in an effort to influence the presidential election,” Brazile declared in a statement Tuesday. “We have been anticipating that an additional batch of documents stolen by Russian agents would be released.”

She also cast aspersions at the Republican nominee. “There’s one person who stands to benefit from these criminal acts, and that’s Donald Trump,” Brazile said. “Not only has Trump embraced Putin, he publicly encouraged further Russian espionage to help his campaign.”

Brazile also suggested that the released documents might be forgeries: “Our legal team is now in the process of reviewing these private documents, and attempting to confirm their authenticity, as it is common for Russian hackers to forge documents.”

The release of hacked documents was announced at a London cybersecurity conference on Tuesday. Guccifer 2.0 was listed in the conference lineup and a person who spoke on behalf of the hacker told the crowd of security experts about the breach.
