The president of London Drugs doesn91裸聊视频檛 know why the company was targeted in a cyber attack that forced it to close its stores for more than week, but Clint Mahlman says hackers with sophisticated methods are 91裸聊视频渃onstantly probing for weaknesses91裸聊视频� of online systems.

Mahlman said in an interview that the Richmond, B.C.-based pharmacy and retailer had been preparing for such a situation for years, and they shut down immediately after the cybersecurity breach was discovered April 28 in order to contain the threat.

Since then, Mahlman said London Drugs has been working with cybersecurity experts to 91裸聊视频渕ethodically go through every system91裸聊视频� and bring them back online in a secure way.

91裸聊视频淲e won91裸聊视频檛 reopen a system until we have the confidence that it is as good as we can possibly make it,91裸聊视频� he said.

He said the company has no evidence to suggest that customer data was compromised.

Mahlman said he has no knowledge if the breach might be connected to B.C. Premier David Eby91裸聊视频檚 announcement late Wednesday that the province had detected 91裸聊视频渟ophisticated cybersecurity incidents91裸聊视频� involving government networks.

Mahlman wouldn91裸聊视频檛 share 91裸聊视频渄etails of any interactions with the threat actors.91裸聊视频�

He said he91裸聊视频檚 sorry that the company couldn91裸聊视频檛 release more details in the days after the incident, but they didn91裸聊视频檛 want to give the attackers any leverage.

91裸聊视频淭he cybersecurity experts deal with these people all the time, and as such, they see certain behaviours from certain threat actors,91裸聊视频� he said.

Mahlman said hackers look at media reports about the cyber attacks, assessing whether the company is aware of the extent of the breach and its ability to recover.

91裸聊视频淭hey use that information to either sustain their attack or leverage in some sort of way against the company.91裸聊视频�

London Drugs will not knowingly give hackers that leverage, Mahlman said.

91裸聊视频淲e apologize to the media and our customers that we couldn91裸聊视频檛 have given more details that they want, but that91裸聊视频檚 our commitment to the safety and security of our systems and our customers.91裸聊视频�

London Drugs said on Tuesday that all 79 of its stores in B.C., Alberta, Saskatchewan, and Manitoba had reopened, and Mahlman said it was a 91裸聊视频渧ery big step91裸聊视频� to shut down its systems companywide to 91裸聊视频渃ontain and mitigate any potential damage.91裸聊视频�

91裸聊视频淭he level of sophistication and expertise of these international cyber threat actors is significant,91裸聊视频� Mahlman said.

In the B.C. government incident, Eby said provincial authorities were working with the Canadian Centre for Cyber Security and other agencies to determine the extent of the problem, but there was currently no evidence that sensitive information had been compromised.

Mahlman said the investigation was ongoing with the help of cybersecurity experts from across the continent, and more work needed to be done to determine what information could have been accessed.

91裸聊视频淲e91裸聊视频檝e never had to shut down all our stores before,91裸聊视频� Mahlman said. 91裸聊视频淚 think the public may be shocked to know, and this is far from unique to London Drugs.91裸聊视频�
