The site was intensively searched for vulnerabilities, according to CERT.LV - the official Information Technology Security Incident Response Institution of the Republic of Latvia.
According to CERT.LV, the security of the website uses the security solutions of the Radio and Television Center and the State Audit Office. The website continued working without interruption during the vulnerability scan.
Baiba Kaskina, a representative of CERT.LV, told the BNS newswire: "All indications suggest that the attack was carried out from resources in Russia."
The most famous example of a Russian-origin cyber-attack on the Baltic states came in 2007 when Estonia bore the brunt of a massive online onslaught from servers in Russia. Ironically, Estonia's ability to withstand the attack wound up cementing its reputation as a leader in IT security and ultimately led to the placing of NATO's cybersecurity center of excellence in the country.
