US Govt Warns of Attacks on Unpatched Pulse VPN Servers

The US Cybersecurity and Infrastructure Security Agency (CISA) today alerted organizations to patch their Pulse Secure VPN servers as a defense against ongoing attacks trying to exploit a known remote code execution (RCE) vulnerability.

This warning follows another alert issued by CISA in October 2019, and others coming from the National Security Agency (NSA), the Canadian Centre for Cyber Security, and UK’s National Cyber Security Center (NCSC).

Pulse Secure reported the vulnerability tracked as CVE-2019–11510 and disclosed by Orange Tsai and Meh Chang from the DEVCORE research team, and by Jake Valletta from FireEye in an April 2019 out-of-cycle advisory.

Dunwoody becomes latest metro Atlanta government hit by cyber attack

Dunwoody officials said Thursday that no data was compromised during the ransomware attack, which was detected on Christmas Eve and is now under investigation by the FBI. The intrusion was quickly identified by staff, which worked with the city’s computer security contractors at InterDev to shut down servers and disconnect computers in order to limit the impact of the attack.

“As soon as we detected a problem, we took immediate steps to protect the city’s infrastructure,” Ashley Smith, InterDev’s director of government services, said in a news release. “Data back-ups were used to fully restore systems with no loss.”

Dunwoody police Chief Billy Grogan said the attackers demanded a ransom be paid in bitcoin, a digital currency. He declined to reveal the amount requested but said the city did not pay.
